Advanced Driver Assistance Systems (ADAS) driver assistance systems. What is ADAS in a DVR

ADAS stands for (Advanced Driver Assistance Systems) modern systems driver assistance.
These are various devices designed to increase the safety of driving.

Typically, these devices include:
- Short range and long range radars
- External and internal video cameras
- parking radar(front and rear ultrasonic sensors)
- Laser rangefinders ( LIDAR- Light Identification Detection and Ranging - light detection and range determination)
These devices are combined into a single whole using a control unit.

Vehicles equipped with ADAS are an intermediate link between ordinary cars driver-controlled and unmanned vehicles.

It is gratifying to note that UAZ has become one of the "pioneers" of the domestic implementation of ADAS systems:
In July 2016 Ulyanovsk car factory held a demonstration of the UAZ PATRIOT car with an electronic system all-round view and driver assistance (ADAS Vision).

The new system combines Surround View cameras and ultrasonic parking sensors. At the same time, the car acquires a new consumer property - it combines the visualization of dangerous obstacles and an audible warning signal.

The developer of the electronic system was the company Abiks-Technology, one of the leaders in the Russian market for the creation and implementation of automotive electronic security systems and driver assistance.

Features new system also is the use of an ADAS camera with lane change warning functions ( LDW- line Departure Warning) and detect obstacles in front of the car ( FCW- Forward Collision Warning). In the future, as part of the development of the ADAS system in the UAZ PATRIOT platform, it is planned to use a 4-channel video recorder, as well as to implement the traffic sign recognition function (Traffic Sign Recognition, TSR), automatic switching high and low beam (Light Assist) and dynamic parking lines(superimposition of the trajectory of the car on the video image before and during the movement).

The Ulyanovsk Automobile Plant presented a demo UAZ PATRIOT car with a working model of the Vision-ADAS system at the 96th International Scientific and Technical Conference of the Association automotive engineers"Prospects for the development of cars", which was held on September 14-15, 2016 in Togliatti.

As part of the conference, participants were able to take a test drive in a car equipped with the latest version of the system. Testing took place both in the city highway mode and at a specially prepared training ground.

Side cameras are located below the exterior mirrors

The camera inside the cabin is responsible for reading the signs.

Thus, the capabilities of the updated system were demonstrated: traffic sign recognition, warning of an involuntary lane change, detection of obstacles in front of the car while driving, a surround view system, visualization of obstacles detected by the security system, as well as assistance in parking the vehicle.
It is also worth noting that in new version visualization of dangerous obstacles and audible warnings are combined.

According to Sergey Shpilev, Project Manager of the Engineering Center of the Scientific and Technical Center of UAZ LLC, the system has undergone significant changes compared to last year's version of Vision-ADAS. “We have significantly expanded the functionality in terms of traffic sign recognition, marking recognition, as well as the detection of obstacles in the form of vehicles in front (Forward Collision Warning, Forward Collision Warning, FCW) , which eliminates dangerous collisions.

You can safely add to driver assistance systems automotive thermal imagers.

Their cost is falling every year and soon they will be used not only in the segment premium cars but also in everyday life.
Today, automotive thermal imagers use a special matrix that reacts to the heat generated by any object. Unlike the first models of thermal imagers, they are not afraid of illumination, and they do not need light in principle.

The image that is displayed on the screen is completely formed based on the heat generated by the object.
Most important parameters for thermal imagers are: refresh rate and lens size.
The frame refresh rate is responsible for how smoothly the picture will be displayed on the screen at high speeds.

Modern thermal imagers for a car see at a distance of up to 300-400 meters, in latest models so-called DSP modules are installed, which can highlight people, animals and cars on the screen, plus signal a dangerous approach.

The ancestor of such thermal imagers to the masses is FLIR, which released the PathfindIR model, it is installed regularly in some trim levels BMW and AUDI.
The second generation of PathfindIR II already has a DSP module that identifies people and animals.

There is already experience in using PathfindIR in UAZ. Such a system was equipped with the Helios mobile searchlight complex.
Moreover, the camera was placed in place of the standard fog lamp.


The competitor of PathfindIR II is the Guide N-Driver of the Chinese manufacturer Guide and the Russian Pergam Driver

In December 2016, UAZ presented a test version of the car UAZ PATRIOT with telematic services

The presentation featured a UAZ PATRIOT vehicle with a comprehensive solution that includes elements of information security and combines the work of a driver assistance system, an ERA-GLONASS system with a telematics platform, a dispatch center and a mobile application on the iOS and Android platforms.

The functionality of the integrated solution allows customers to automate services for multi-user control of access to the car, control of the driving style, compliance with the route and traffic rules by vehicle drivers. The system makes it possible to timely control fuel consumption, plan maintenance and repair of vehicles based on the information received about the condition of vehicles.

The operation of the complex is carried out due to the telematics unit installed in the UAZ PATRIOT vehicle, connected to the electronic system of the vehicle, receiving the navigation signal from the satellite, which collects information about the state of the vehicle and transmits it via a cellular communication network to the server of the telematics platform. Further, the information is processed and systematized on the server and transmitted to the dispatcher for analysis and further interaction with the driver or directly with the car by sending commands.

At the same time, the integration of driver assistance systems into telematic services allows the dispatcher to timely detect the presence of absent-mindedness, fatigue, drowsiness or aggressiveness in the driver and, thereby, to take preventive measures to improve driving safety.

A feature of the presented solution is the presence in the UAZ PATRIOT of the “SERVICE” button, with one click of which the driver can contact the dispatcher at any time, who sees the position of the car on the map, received from signals from GLONASS satellites. The presence of such a button allows you to solve a lot of operational issues, such as calling an ambulance, technical or legal assistance right on the road, etc.

This solution allows integration with information systems corporate clients, which can significantly improve the safety of driving vehicles and achieve significant savings in operating costs. Using the system enables customers to save on average 15% on fuel consumption due to the termination of drains and deviations from routes, reduce the distortion of vehicle mileage, reduce vehicle downtime for maintenance and receive additional discounts on vehicle fleet insurance. Simultaneously mobile app(platforms iOS, Android) will allow you to timely receive the information required for prompt management decisions.

Deputy CEO development director scientific and technical center UAZ LLC Evgeny Galkin noted: “UAZ is the first company in the Russian market presented a comprehensive solution in the field of telematic services with elements of information security, which can be serially installed on a car directly at the automaker's enterprise and customized to the needs of a particular client. We are convinced that this decision will be most in demand among corporate customers, since the use of telematic functions in practice can significantly increase driving safety and achieve significant cost savings in the operation and maintenance of the company's vehicle fleet.

The fewer distractions you have from driving, the more fun you get. That is why the BMW 3 Series takes over independent execution many tasks. The Driving Assistant warns you of potential dangers in good time, the Navigation System Professional guarantees you a trip without unpleasant surprises even in unfamiliar terrain, and whole line onboard assistants make the parking process as easy and comfortable as possible.

Driving assistant.

The Driving Assistant package includes a range of camera-based systems, such as Lane Departure Warning or Collision and Pedestrian Warning with City Braking.
Lane Tracking System controls road markings and warns the driver with a slight vibration of the steering wheel in the event of an inadvertent departure from the lane at speeds above about 70 km/h. The warning is not given if the lane change is intentional - that is, if the corresponding turn signal has been turned on.
Collision and Pedestrian Warning with City Brake function reacts to other vehicles and monitors pedestrians. If the vehicle in front brakes hard, the BMW 3 Series immediately reacts by activating the collision warning system. It works in three stages: first, the warning indicator lights up, then the indicator flashes and the system beeps, and finally the system gently applies the vehicle's brakes (when driving at speeds up to 60 km / h). The Pedestrian Collision Warning System operates at speeds between 10 and 60 km/h and gives a warning signal in the event of a critical danger. At the moment when a warning signal is given, the vehicle's brake system is automatically activated, providing a minimum response time to pressing the pedal. The effectiveness of this function may be limited by dark time day or during fog.

ACTIVE CRUISE CONTROL WITH STOP&GO.

Active cruise control with Stop&Go function, including radar collision warning system with braking to a standstill function, ensures maximum comfort and traffic safety. The system automatically maintains the speed set by the driver and the distance to the vehicle in front. The car accelerates and decelerates automatically until it comes to a complete stop, controlling the distance even in heavy traffic and traffic jams. If the vehicle begins to approach the vehicle in front, or if another vehicle changes lanes between it and the vehicle in front, the system accurately adjusts the speed to match the changing traffic situation. The system can be activated at speeds up to 210 km/h.
The Stop&Go function not only provides automatic deceleration to a complete stop, but also independently accelerates the car to set speed, if the traffic situation allows it again within a certain time interval.
If the vehicle in front brakes sharply, bmw car instantly reacts to this by activating the collision warning system. It works in three stages: first, the warning light comes on, then the light starts to flash and the system beeps, and finally the system applies the vehicle's brakes hard.

HEAD-UP DISPLAY BMW.

The BMW full color head-up display allows you to display the entire important information directly in the driver's field of vision, allowing him to fully concentrate on driving. This information includes current speed data, as well as, depending on equipment, navigation prompts, a speed limit indicator with no-overtaking zones, a phone book, multimedia system playlists, as well as data and warnings. various systems assistance to the driver.
Symbols on windshield displayed in full color and high resolution. virtual image projection display located approximately 2.3 m ahead of the vehicle. In combination with optimal positioning in relation to the driver's seat, this ensures the fastest and most convenient reading of information without unnecessary distractions.
The brightness of the head-up display is automatically adjusted according to the external lighting. In addition, the display provides two display modes: for light and for dark time of the day. The image height can also be adjusted. And to top it off, the driver can also customize what information, in addition to the current speed and driver assistance systems warning indicators, is displayed on the head-up display.

Parking assistance systems.

The BMW 3 Series Sedan can be equipped with a range of intelligent systems designed to make it easier to maneuver in narrow parking spaces. Helpful assistants such as the reversing camera, the parking assistant or the surround view system significantly increase comfort in all parking situations - especially in tight spaces or in situations where visibility is limited.

  • Rear View Camera

    The rear view camera allows the driver to display an image of the space behind the vehicle on the Control Display when parking or maneuvering. It allows you to significantly improve visibility when reversing at speeds up to 15 km / h.
    The control display will also show hints, marker lines and obstacles in different colors to help the driver determine if the parking space is large enough to park the car. When turning the steering wheel to extreme position red heading lines and green heading lines appear on the display to indicate the vehicle's path depending on the steering angle.
    The rear view camera is automatically turned off when driving forward for ten meters or at speeds above 15 km/h. In combination with towing device The camera greatly simplifies the process of attaching a trailer thanks to the practical zoom function.

  • Parking assistant

    The parking assistant allows you to significantly simplify both parallel and perpendicular parking car. Regardless of the current status, the system automatically measures potential parking spaces - including bottlenecks for parallel parking - when the car is moving at a distance. high speed(up to 35 km/h) and at a distance of no more than 1.5 m from parked cars. When a large enough space is detected, the driver simply needs to turn on the turn signal, and the parking assistant takes steering on itself - the driver only needs to shift gears and press the accelerator and brake pedals, taking into account the system prompts on the control display and acoustic signals.
    When approaching an obstacle at low speed, the parking assistant is activated automatically thanks to the "Auto PDC" mode. The extended functionality of the system also provides assistance to the driver when parking perpendicular to the direction of travel. The parking distance warning sounds when the vehicle approaches an obstacle from either side too close. Thanks to this, the parking process becomes even more calm and safe for the driver.

  • Surround View System

    The Surround View System includes camera-based top view and side view functions, as well as a rear view camera. Cameras located in the exterior mirrors and at the rear of the vehicle provide a 270° view around the vehicle.
    The top view allows you to control the areas on the sides of the car, making it easier to maneuver. The side view provides the safest way to overcome difficult areas, such as exiting adjacent roads or passing difficult intersections with obstructed visibility. Two digital cameras located in the front of the car on the left and right right side, track traffic situation in front of the car. They allow early detection of approaching vehicles and therefore give the driver more time to react. The side view function is deactivated automatically at speeds over 15 km/h. Of the three possible view modes - rear view camera, side view or top view - only one can be selected for display at a time.
    Camera-based systems are activated when reverse gear is engaged or when the PDC button or side view button is pressed. Images from the cameras are displayed on the control display.

Navigation system Professional.

The navigation system Professional is distinguished by its elegant design and impressive functionality. It provides a convenient and easy-to-use navigation experience, perfectly integrated with BMW features like iDrive control concept or iDrive touch controller. The system includes a USB hands-free module with voice control, a BMW Professional audio system with DVD player, and HDD 20 GB for storing audio files. The system greatly simplifies the use of the Online Traffic Information (RTTI) function. The built-in 8.8" LCD color display with 1280 x 480 pixels resolution and multi-window function (main and sub screen) ensures optimal readability and maximum convenience.

The scientific and technological revolution began its run in the middle of the twentieth century, and still cannot stop. This is especially noticeable when looking under the hood. modern car: vehicles today have become real fortresses on wheels that can protect the driver from many troubles. And not the last role in this whole story with the guarantee of a successful trip is played by car security systems.

Every day, the designers of automobile concerns complicate the drawings of cars, making them more intricate and incomprehensible to the average user. Today the ball is ruled intelligent systems safety, as well as various means to ensure comfortable driving. And given that the situation on the roads of the world, to put it mildly, is far from ideal, then a car that is not equipped with modern means passive and active safety, it is more and more difficult to “break through” to the buyer.

ABS - anti-lock braking system

Task ABS(anti-lock braking system) is to prevent the braking vehicle's wheels from locking up, as well as to maintain its controllability and exchange rate stability.

When the wheels are blocked, and the car seems to be about to break into a skid, the electronics begin to methodically “release” and “press” brake pads which allows the wheels to turn. Efficiency ABS systems depends primarily on how well it is configured. If, for example, it works too early, the braking distance can be significantly increased.

Operating principle

The way ABS works is quite simple. Wheel rotation sensors emit signals that are sent to a computer that analyzes them. There is an imitation of actions professional driver, which uses the intermittent braking method.

How effective is this system? It should be noted right away that since its appearance, disputes have not ceased over whether it is more beneficial or still harmful. But be that as it may, even the opponents of ABS cannot ignore such useful qualities as a significant reduction stopping distance, as well as maintaining control over a multi-ton car during emergency braking. Yes, when the ABS is activated, it is very difficult to calculate the length of the braking distance, but it is better to stop in complete ignorance for no one knows how many meters before the lamppost than to “kiss” it, knowing exactly how long the car will stretch during braking. Two opposing camps decided to agree that ABS will come in handy Not experienced drivers, and Schumachers will always be able to beat the system. But we are talking about revolutionary scientific thought, so today we can safely say that in the battle “ABS is an experienced driver”, of course, electronics will win an unconditional victory.

Modern multi-channel ABS allows you to get rid of even the vibration of the brake pedal when the system is on. Once upon a time, the cause of traffic accidents was the abrupt operation of the ABS: the pedal began to vibrate, and the car began to moan, so inexperienced motorists were frightened and released the brake. Today, you need to be extremely sensitive to feel how the ABS, which is part of standard equipment almost all cars. At the same time, it serves as the basis for other more complex electronic security systems.

ASR - traction control

At the system ASR(anti slip regulation) there are many names, the most common of which are TRC, or " traction control», STC, ASC+T And TRACS. This active vehicle safety system works in close conjunction with ABS and EBD and is designed to prevent wheel spin, regardless of the condition of the road surface and the force applied to press the gas pedal. As we said above, many security systems work on the basis of ABS. So ASR uses sensors anti-lock braking system, fixing the slipping of the driving wheels, reduces the engine speed and, if necessary, brakes the wheels, providing an effective set of speed. In other words, even if you "drown" the gas pedal to the floor, ASR will not burn rubber and grind asphalt.


Today, cars are even equipped with night vision devices.

Photo

The main purpose of ASR is to ensure the stability of the car when abrupt start or when driving uphill on which road. "Scrolling" of the wheels is leveled due to the redistribution of the torque of the power plant to those wheels, which in this moment have better grip with the road surface. ASR is subject to certain restrictions. For example, it works exclusively at speeds not exceeding 40 km / h.

Flaws

It is impossible not to mention some of the shortcomings of this system. So, ASR will greatly interfere with experienced drivers trying to pull out a stuck car “in buildup”. The system will slow down and release gas out of place and out of time. There are cases when the traction control system “strangled” the engine so much that the car could not move at all.

Or, for example, active drivers. Im ASR puts spokes in the wheels when controlled skid, controlling this drift with traction. But this is nothing compared to the benefits that the system brings: it locks the differential, brakes the wheel loaded in the corner, and equalizes the speed of rotation of the wheels, allowing you to make the most efficient use of the torque of the "heart" of the car.

Many automakers today are forgetting about street racers and making ASR non-disableable. But can something stop our inventive drivers? They simply remove the fuse and indulge their racing ambitions. However, there is a “but” here: if you are sure that ASR will prevent you from putting speed on a leash, we remind you that this system used in Formula 1 cars.

EBD - distribute the braking force

EBD(electronic brake distribution), or EBV- This is an active car safety system responsible for the distribution of braking force between all wheels. Again, EBD always works in parallel with the underlying ABS.

It is noteworthy that EBD takes effect before the ABS reaction, or insures the latter if it is faulty. Since these systems are closely related and always work in pairs, the general abbreviation ABS + EBD can often be found in catalogs.

Thanks to EBD, we get optimal grip on the road, a significantly increased directional stability of the car during emergency braking, as well as a guarantee that control over the car will not be lost even in a critical situation. In addition, the system takes into account factors such as the vehicle's position relative to the road and the vehicle's load.

Brake assistant - safe braking

Brake Assist (BAS, DBS, PA, PABS) is an active vehicle security system that works in tandem with ABS and EBD. It turns on at the moment of emergency braking, when the driver does not press the brake pedal hard enough, but quite sharply. Brake Assist independently measures the force and speed of pressing the pedal and, if necessary, immediately increases the pressure level in brake line. This allows braking to be as efficient as possible and significantly reduce the braking distance.


Brake Assist

The system is able to distinguish the panic actions of drivers or those moments when they put pressure on the brake pedal for quite a long period of time. BAS will not come into operation when hard braking, which are included in the category of "predictable". Many believe that this system is an assistant mainly for the fairer sex, because lovely ladies sometimes simply do not have enough strength to carry out emergency braking. Therefore, in a critical situation, the Brake Assist system comes to their aid, which “squeezes” the brake to maximum deceleration.

EDL: blocking the differential

EDL(electronic differential lock), which is also called EDS, is the system responsible for the differential lock. This electronic assistant makes it possible to increase general security vehicle, improve its traction characteristics under adverse conditions, facilitate the starting moment, provide intensive acceleration, as well as hill climbing.


Photo

The differential lock system determines the angular velocity of each of the drive wheels and compares the results. If the angular speeds do not match, for example, when one of the wheels slips, the EDL slows down the slipping wheel until its rotation speed is equal to the speed of the other drive wheel. If the speed difference reaches 110 rpm, the system switches on automatically and operates without any restrictions at speeds up to 80 km/h.

HDC: traction control during descent

HDC(hill descent control), and DAC And DDS- electronic traction control system for descent from how many and steep slopes. The functioning of the system is carried out through the braking of the wheels and "suffocation" power unit, however, there is a fixed speed limit of 7 km/h (with reversing speed does not exceed 6.5 km/h). This passive system, which is turned on and off by the driver himself. The controlled downhill speed depends entirely on the initial speed of the vehicle, as well as on the gear engaged.


Photo

The speed control system allows you to take your mind off the brake pedal and focus solely on driving. This system is equipped with all four-wheel drive vehicles. HDC, in automatic mode which includes brake lights, turns off immediately after the vehicle speed exceeds 60 km / h.

HHC - light lifting

Unlike the HDC system, which helps drivers descend steep slopes, HHC(hill hold control) prevents the machine from rolling back when driving uphill. Alternative names for this security system are USS And HAC.


Photo

The moment the driver stops interacting with the brake pedal, HDC continues to hold high level pressure in the brake system. Only at the moment when the motorist presses the gas pedal hard enough, the pressure decreases, and the car starts moving from a place.

ACC: car cruise

ACC(active cruise control) is adaptive cruise control, used to maintain a given vehicle speed and control a safe distance. PBA(predictive brake assist) is a predictive braking system that works in conjunction with adaptive cruise control.


Cruise control

If the distance to the vehicle in front decreases, the system starts to slow down until the distance is restored to a predetermined level. If the vehicle in front begins to move away, ACC starts to pick up speed.

PDC - controlled parking

PDC(parking distance control), in common Parktronic- a system that uses ultrasonic sensors to determine the distance to an obstacle and allows you to control the distance when parking.


Parktronic

Photo

The driver is informed about how far is the distance to the nearest obstacle special signals, the frequency of which changes with a reduction in distance - the closer the car is to dangerous area, the shorter the pause between individual signals. After the obstacle remains 20 cm, the signal becomes continuous.

ESP - guarantee of exchange rate stability

At the system ESP(electronic stability program), probably the most alternative names in which the devil will break the neck of the thigh: ESC, VDC, DSTC, VSC, DSC, VSA, ATTS or Stabilitrac. This active safety system is responsible for vehicle stability and works in conjunction with ABS and EBD.

At the moment when the danger of skidding arises, ESP enters the scene. By analyzing wheel speed, brake line pressure, steering position, yaw rate and lateral acceleration, ESP calculates in just 20 milliseconds which wheels need to be braked and how much engine speed needs to be reduced in order to stabilize the car.

Electronic security systems do not at all turn our cars into highly intelligent robots that can do all the work for the driver. The cornerstone in this case is still the driver, who must be able to soberly assess traffic situation, their capabilities and the capabilities of their car. And, as you know, there is no more dangerous illusion than the illusion of one's own invulnerability.

In 2017, almost all premium DVR models, especially those made in Korea, are equipped with elements of the ADAS system. Although this functionality began to appear in DVRs much earlier, it was 2016-2017 that became the trend year for advanced ADAS functionality. What is hidden under this abbreviation and is it worth overpaying for these features?

ADAS (advanced driver-assistance systems) is a driver assistance system. It is a set of specific algorithms that varying degrees assist the driver in making quick decisions for safe and easy driving.

Foreign premium cars often have built-in ADAS system tools in on-board computers, for example, a system from NVIDIA can distinguish and identify Various types objects while moving. Or everyone known system safe braking from VOLVO when approaching an object (pedestrian or car), in fact, is also an element of the ADAS system.

But what to do if your car does not have even the simplest ADAS systems? And you suddenly heard that they are in the video recorders? Is it worth it to buy devices that already have some security features?

In car DVRs, everything is much simpler so far, since computing power is generally limited, and programmers are in no hurry to write scripts for such a narrow market.

The most advanced DVR models are usually Korean production Thinkware, Iroad, BlackVue, VicoVation, etc. , have a certain set of elements of the ADAS system, but they are designed only for the identification of objects using a video camera. Let's take a look at the most common ones:

  • FCWS(uFCWS) Forward Collision Warning System is an element of the collision warning system. If there is a rapid approach to the object at a speed of up to 30 km per hour, the DVR warns of danger sound signal and the picture on the screen
  • LDWS Lane Departure Warning System is an element of the lane departure control system. If there are lane markings on the road, the DVR monitors them and warns the driver with a sound effect and on the screen if the car starts to leave it. This function is enabled only when a speed limit is set, for example, more than 60 or 100 km per hour to separate the city from the highway
  • FVSA Forward Vehicle Stop Alarm - a warning about the beginning of the movement of the object ahead. If you are in a traffic jam and the car in front of you has moved forward, and at that time you are looking at your mobile, the system will issue a warning that it is time to move
  • PDW Pedestrian Detection Warning System element of the pedestrian detection system at a certain speed, warns of the appearance of objects in front of the car seconds before the collision. Requires the installation of a special camera with narrow optics
  • BSD Blind Spot Detection is an element of the blind spot monitoring system. Signals about the object in the blind zones, requires additional cameras or sensors, in addition to the standard DVR with 2 cameras.
  • moving car detection- a dangerous start of the car, the uncontrolled movement of the car is monitored and a warning is issued about it. This refers to the movement of the car when the surface is tilted (uphill)
  • over speed- in the presence of GPS module and the corresponding settings on the screen and sound, the driver is warned about exceeding the set speed limit
  • rear view camera- works similarly to a parking camera in 2-channel systems, when moving backwards, a picture with rear camera
  • emergency call or SOS button - a panic button or an automatic trigger that, when a G-sensor of a certain strength is triggered (as if an accident had occurred), reports via the Internet or via SMS from your phone about the event to the emergency services

Don't understand how it all works? Watch the video from Thinkware, which shows live the various elements of the ADAS system, and everything will become clear to you right away.

And yet, is it worth buying a DVR just because it has a driver assistance system? We can only say unequivocally that this parameter should not be the main one when choosing a model. But the convenience that some elements will bring is obvious that it exists. But are all elements needed?

Eg, element LDWS will not work in snowy conditions where the markings are not visible. The same applies to roads without markings (which is not a wonder in Russian conditions even in big cities).

Element PDW works only with narrow optics and as standard, as well as the blind spot monitoring system BSD, never enters.

Speeding warnings are often issued by the navigator that many people use. And does anyone observe us speed mode up to 60 in the city?

A panic button with a shock sensor has been built into new cars since the beginning of 2017 by default, so it does not seem to be required additionally.

The element of the beginning of the movement of the picture from the rear camera can really come in handy for those who do not have it in the package. Also FCWS And FVSA can be useful when driving in traffic jams, where cases of driver distraction from vehicle control are not uncommon.

conclusions

In general, there is a sense in ADAS, although in DVRs it is for the most part a marketing component to attract attention, but some elements will not be superfluous either.

Relax and let your BMW drive. Traffic Jam Assist significantly reduces driver stress in monotonous situations on European and US highways. When moving in dense stream at speeds up to 60 km/h, it automatically adjusts the speed depending on the situation, allowing you to comfortably overcome any traffic jams. The system maintains a distance from the vehicle in front, independently regulates the speed (if necessary, slowing down to a complete stop) and engages the steering. Thus, in order for the car to move independently in its lane, you just need to keep at least one hand on the steering wheel.


A thruster assisted lane keeping system, incorporating a traffic jam assist system, can be used to assist the driver in monotonous driving conditions. At speeds from 0 to 210 km/h, it automatically corrects the direction of the car, keeping it in the center of the lane. The high-tech steering function uses data from multiple radar sensors and a stereoscopic camera. The system positions the vehicle in relation to the lane markings and the vehicle in front (if any). It automatically maintains a distance and actively controls the direction and speed of the car (if necessary, slowing down to a complete stop). The Steering Lane Keeping System represents the next step towards fully automated driving. Even though the system is actually capable of driving the car on its own, legal regulations still require the driver to keep both hands on the steering wheel while driving. If the driver violates this requirement, the system will record this with the help of sensors and, after a certain time, will give an audible warning. After that, it will go into standby mode. The system will also switch to standby mode if the lane change indicators are turned on, or if the requirements necessary for the operation of the system are no longer met (for example, the lane becomes too narrow).


Precisely reacts to any danger: in a critical situation, active safety systems take protective measures- the seat belts are pretensioned, the seats are moved to the upright position, the windows and sunroof are closed. After the incident function automatic braking brakes the car to a complete stop - this prevents or reduces the likelihood of repeated collisions. To prevent dangerous situations from developing at an early stage, the attention monitoring system evaluates the driver's behavior for any symptoms of fatigue.


Save your chosen course. The Lane Departure Warning system, including the Collision Warning function implemented by the camera system, monitors road markings at a distance of 50 m and a speed of approximately 70 km/h. As soon as you cross road markings to the left or right of your vehicle without turning on the appropriate turn signal, the system warns you by a slight vibration of the steering wheel after receiving the appropriate signal from the camera. With the help of a video camera, the Collision Warning feature detects vehicles in front and warns you if the distance is close dangerously or if a collision is imminent. Thanks to this, you can react in time and avoid an accident.


Your BMW is looked after for you. In cases where another vehicle is approaching at high speed or is in dead zone” and therefore invisible to you, it is often difficult to correctly assess the situation and the potential risks associated with it. If in the adjacent lane is vehicle, the radar sensors will warn you by displaying a special symbol on the side mirrors. If you turn on the turn signal at this time, the steering wheel will vibrate and the symbol will flash.
