How to operate the automatic harvester box. Additional modes of automatic transmission

The advent of the automobile gave rise to an ongoing race to improve all the systems and mechanisms of this vehicle. From methods and materials for the body to high-tech control methods. Karl Benz came up with the first device that allows in several modes to transfer engine forces to the running system.

The progressive thought of several generations of designers and inventors brought this device to the gearbox known to us today. But car manufacturers were not going to stop there, and already at the beginning of the last century, attempts began to automate this process. By the 30s of the XX century, manufacturers came close to solving the problem. But neither technologically nor economically mass production it was impossible to establish, although it was possible to create successful prototypes.

the first stock car with an automatic transmission is consideredBuickRoadmaster released in 1947. The first model had only two gears, but a few years later a three-speed automatic transmission was launched into the series, which has not fundamentally changed to this day, although modern transmission became several orders of magnitude more precise and more complex.

How automatic transmission works and its types

There is no clutch pedal on machines with an automatic, except for those models where it is possible to switch to manual control. This essential role performs automatic transmission. The energy of the engine through a complex mechanism, which will be discussed below, is transferred to the transmission. The device of the system is designed in such a way that the switching of modes is regulated by automation. How this happens can be understood by understanding the operation algorithm and the main components of the automatic transmission:

• torque converter. Represents the evolution of a clutch developed back in 1903. The place where torque is transferred from the engine to the output shaft. The principle is simple. A pumping turbine connected to the engine accelerates the oil inside the housing, which transfers energy to the blades of the gearbox mechanism. Thus, there is no rigid mechanical connection between the input and output shafts. In this case, the transformation of the torque does not occur. Provides her additional element called a rotor. It is located between the turbines and the special design of the blades gives additional torque. power plant. The force is transferred to the mechanism directly responsible for the change gear ratio;
• planetary reductor. The main part of the automatic transmission. A complex mechanism assembled from a central or sun gear, a crown or a large central gear and a set of satellites mounted on a part called a carrier. changing position individual elements Automatic transmission along the axis, several combinations are formed that output several speeds of rotation of the central shaft. The number of options is commonly referred to as transmissions.. A direct analogue with a manual transmission, but the circuit does not need a clutch, the function of which is performed by a fluid coupling. Similar system needs accurate and complex management. It is impossible to ensure efficient switching of such a complex mechanism in manual mode;
• control system. Two types of devices are possible. The first is hydraulic mechanisms. Today, this type is mainly used in budget cars. Cars of the middle class and above are equipped with automatic transmission with electronic control. In the first case, the sensors, reacting to a change in oil pressure in the system, actuate hydraulic pushers. They actuate a complex combination of clutches and brakes by mechanically shifting gears. The system is set up in such a way that it is impossible to “jump over” the transmission. Switching is possible only sequential. Electronic system management more efficiently. Sensors collect over full information about the operation of the automatic transmission. This is the temperature of the liquid, and the speed of rotation of each axis. The control unit gives a signal to the actuators. The triggering algorithm for a whole group of parts at once is under the control of electronics. Clutches, brakes and solenoid valves, often referred to as solenoids, are almost constantly in motion while riding;
• selector lever. This is the "handle" located in the cabin. All over the world, the marking of the selector positions common to all automatic transmissions has been adopted.R- reverse. N - neutral gear.D - the main position of the selector when driving, from start to stop.P - Parking.S - sport mode. Some manufacturers of elite and executive cars supply the switch block with additional provisions. For example, Tiptronic has the ability to switch from automatic mode to mechanical control Checkpoint.

The scheme discussed above refers to the classical version. The principle of operation of variators and robots is different. The difference in price is also significant.

Well-established technologies, large production volumes classic automatic transmission make it more accessible and variator, and robotic box, which, however, have some advantages.

For example, the variator does not have switching stages at all, and the gear ratio changes are carried out by a mechanism resembling two conical pulleys. The moving belt simultaneously changes the input and output shaft diameters, which changes the output speed without power loss and jerks. The robot is essentially a high-quality manual transmission with efficient electronic control. Fans of mechanics can always switch to their favorite mode.

Advantages and disadvantages

The advantages of automatic transmission are many. Managing mechanics requires a lot of learning and constant attention while driving. This problem does not apply to owners of cars with automatic equipment. Most of the time when driving, the box is in one position - D, which means movement or drive. But these are not all bonuses. The advantages are as follows:

1. Comfort and focus on traffic situation and not on appliances.
2. Saving engine life. The machine does not allow mechanics to work in critical modes, which prevents wear of the main parts and Supplies.
3. Safe driving in difficult climatic conditions. Together with other systems, the machine does not allow the driver to make critical mistakes in control.

However, not only the advantages are noted by specialists and ordinary car owners. There are also disadvantages:

1. Higher than manual transmission fuel consumption. The efficiency of the machine can be up to 12% lower than that of mechanics. However, this does not apply to last generation automatic transmission. Improving production technologies today reduces this difference to a minimum.
2. Dynamics. Auto mode does not allow the vehicle systems to work in extreme conditions, which deprives the driver to fully feel the full power and capabilities of the car. But for most city dwellers, this is not the case. In everyday life, where progress is complicated by traffic jams, crossings and traffic lights, the automatic machine is more of a blessing than a disadvantage.
3. Car cost. Models with automatic transmission are much more expensive than their counterparts with manual transmission.
4. Impossibility of towing. If the transmission breaks down, you have to call a tow truck. The ability to move the switched off machine is limited to a small distance of minimum speed, and then with experience and knowledge of how to do it safely for the mechanics of the car.
5. Repair. The complexity of the design and the high price of spare parts and maintenance, which includes more consumables, makes owners of cars with automatic transmission shell out.

How to drive a car with an automatic transmission

There are no difficulties in training and subsequent operation. Unlike mechanics, you do not need to look at the tachometer needle or determine the moment of switching by sound. The positions of the handle of the machine are as follows:

• Parking. Indicated by the letter P. In this position, the blocked output shaft prevents the vehicle from moving. On level ground, this is enough to maintain stability, but on an inclined surface, it is recommended to use the hand brake;
• The position of the handle N corresponds to the neutral gear on the manual transmission. With the control system turned off, the machine can be moved;
• Reverse is indicated by the letter R, which means reverse. In this position, it is impossible to start the engine, and when moving forward, a sharp shift of the selector to reverse will certainly disable the gearbox;
• The main position is marked on the selector with the letter D. Switching all gears forward, from the lowest to the highest, occur in this mode.
• Additional Provisions. These include the Sport mode, marked as S. This mode makes the most of the engine power. Acceleration dynamics is noticeably higher for vehicles with additional option kickdown. For uniform and economic movement overdrive function possible. Some models have a separate switch in winter mode. If the automatic transmission breaks down, the automation can block the mechanism in the current gear and go into emergency mode.

Features of operating a car with automatic transmission

The order of operations required to start moving on most machines with a machine gun is the same:

1. Insert the key and turn it to ignition mode.
2. Press the brake pedal.
3. Move the selector lever to the desired position. Either forward or backward.
4. Release the brake pedal.

The car will begin to move smoothly in the selected direction, without even pressing the pedal, using which you can accelerate the dynamics. The machine first of all reacts precisely to the operation of the accelerator. Drive mode is not switched during short stops, for example, at a traffic light. Only brakes are used. The "Parking" position is turned on for a longer stop.

• Off-road and uneven surfaces should be avoided. Slippage should ideally be avoided in general;
• You need to let the system warm up. Automatic transmission will reach the declared level only at a certain oil temperature. Therefore, even in summer time better first a few minutes of movement to avoid sharp accelerations and high speeds
• Do not overload. The machine has a more sensitive mechanics, which is designed for certain loads. It is strongly not recommended to overload the interior or pull a heavy trailer;
• You also need to pay attention to the documentation. Is it allowed to tow of this type automatic transmission. Some models are not subject to forced movement at all. Some species have strict speed and distance limits.

The global trend today is, of course, cars with automatic transmission. Characteristics in many ways approached highly skilled driving on mechanics. Conveniences are undeniable and do not need additional advertising.

Driving a car equipped with an automatic transmission is quite simple, difficulties arise for beginners who are not familiar with the principle of operation of an automatic transmission and with its design features.

You drove a car with a manual transmission and do not belong to the "dummies"? Then, at first, driving an automatic transmission, watch the position of your left foot. The acquired habit of pressing the clutch pedal, which is absent on cars equipped with automatic transmission, can interfere with driving. Obviously, before driving a car equipped with a selector, learn to use only one foot - quickly move your right foot from the gas pedal to the brake, without remembering the clutch.

The gearshift lever in cars equipped with automatic transmission is called a selector, it is additionally equipped with an unlock button that prevents incorrect gear shifting. The main advantage of this type of gearbox is the possibility of selecting a gear ratio corresponding to the driving conditions by electronics, without the participation of the driver. There is no need to learn how to smoothly shift gears: the “smart” box copes with this task on its own.

Driving a car equipped with an automatic transmission begins with the study of the main operating modes of the unit, which have the appropriate designations:

1. "P" - parking, used to start the engine. The selector switches to this position when the vehicle is completely stopped or when using the handbrake. Some manufacturers of vehicles with automatic transmissions indicate in the instruction manual of the machine the need to use hand brake during the application of the "Parking" position.
2. "D" - move forward, allows the car to move forward. From the degree of pressing the "gas" pedal and the driving conditions of the vehicle, the gears will be selected automatically. When in this mode, the machine will not roll backward if the machine is on a slope unless the slope is too steep.
3. "R" - reverse, allows the car to move backward. This position is activated after the car has completely stopped, plus when the “brake” pedal is depressed.
4. "N" - neutral, used to warm up the engine in the cold season, it is not recommended to switch the selector to the specified position while the car is moving. Provides idle work power unit without transmitting torque to the wheels.
5. "D2" (or S) - downshift, used on descents, ascents. It will be more efficient to stop the car in this mode than in the “D” position. The box will use only two gears - first and second.
6. "D1" (or L) - the subsequent gear reduction range, used when roads are iced, mountain serpentine, in some cases can be used for engine braking. In this mode, the car will always move in first gear.

Switching the selector from position "D" to position "D3" (D2), "D2" (D1) is performed when the machine is moving. Advanced automatic transmissions have additional acceleration modes:

• economical - "E";
• normal - "N";
• sports - "S".

Practical lessons

Set the selector to the desired mode by doing the following:

1. Start the engine (you can only switch the lever when the engine is running).
2. Depress the brake pedal.
3. Click desired button mode located on the selector (if necessary).
4. Select the position that corresponds to the desired direction of movement of the machine: "D" - the vehicle will go forward, "N" - neutral, the car will stand still, or roll downhill, "R" - will go back. When you turn on the gear selected by the driver, the car will not start moving, and when you release the “brake” pedal, the car will go. Consider this nuance, do not take your foot off the “brake” ahead of time in order to avoid an accident.

Automatic boxes recognize the driver's commands by pressing the "gas" pedal: smooth acceleration, gradual gear shifting is provided by pressing with little effort. The intensive acceleration necessary for overtaking is achieved by pressing the “gas” pedal to the floor, while the automatic transmission will first shift into a lower gear, then the car will start to accelerate. Keep in mind: from the moment you press the “gas” pedal until the vehicle accelerates, there is a slight delay, about one second, this time is imperceptible when driving slowly, and in overtaking conditions can be fatal.

Having decided to stop the movement of the car, press the brake pedal. During a short stop, at a traffic light, do not move the selector from the “D” position - extend the resource internal mechanisms automatic transmission.

Keep the brake pedal depressed after stopping the machine in the following situations:

1. Long stops (traffic jams), the depressed brake pedal will allow the engine to rest, fuel will not be burned in vain, use the “N” position.
2. The machine is on a slope, the selector is not moved to the "P" position.

The above instructions for "dummies" will allow you to drive a car with an automatic transmission. Note: it is better to learn right away proper driving so as not to harm the automatic transmission. It is difficult to correct bad driving habits.

Additional Modes

Additional automatic transmission modes include:

1. Winter mode, has the designation "*", "W", "SNOW", "HOLD", "WINTER". According to it, slippage is excluded during gear shifting and when the vehicle starts moving. The machine starts moving from the second gear. Switching to other gears occurs at lower drive speeds - this allows you to eliminate drops in the operation of the box during acceleration, and reduces the likelihood of the car skidding. Experts clarify: you should not use this mode in the summer - you can get overheating of the box due to reaching maximum load to the unit.
2. The "D" position sub-modes limit acceleration beyond a certain gear range:

• "S" or "Z" - ensuring the inclusion of a gear no higher than third. These positions are used on sections of the road that require increased attention from the driver. When driving, use the "Z" mode, while watching the tachometer readings, its arrow should not fall into the red zone.
• "2" - the restriction of the inclusion of gears not higher than the second, the car moves at a speed of no more than 80 km / h. Used on steep slopes slippery roads.
• "1", "L" - used for difficult conditions machine operation: off-road driving, steep grades. Only transmission, speed not more than 40 km / h.

Additional Modes the operation of automatic gearboxes allows you to control the machine under adverse conditions. Please note: accidental activation of submodes "1", "2" when high speed will lead to a sharp slowdown in the movement of the car, provoke a skid of the vehicle.

The automatic transmission can be controlled inexperienced driver, the following recommendations will extend the life of the automatic transmission:

1. You can not give a large load on an unheated box. Transmission oil warms up more slowly motor fluid. When driving a machine with the specified gearbox type, drive a few kilometers at low speed.
2. Avoid wheel slip: do not press the "gas" sharply if the road surface is uneven.
3. Try not to tow trailers or other vehicles.
4. Refuse to turn on the neutral when the car is moving.

Proper operation automatic box allows you to enjoy driving and prevents premature failure of the unit, allowing the mechanism to work normally.

How to check gearbox oil The automatic transmission jerks the car when shifting gears

With a gun, you need to start it and warm up the engine. The colder it is outside, the longer it takes to wait before driving.

It is important to remember that starting a car with automatic transmission is possible only when the gear lever is in the neutral position N or P.

To be able to move, you must switch to the appropriate mode. To drive forward - put the lever in position D, back - R. Press the gas only after you feel a slight push, which means that the car has taken off the "neutral".

It is also important not to forget to remove the car from the handbrake.

How to drive a car with an automatic: pedals

In a car with automatic transmission, unlike a car with mechanical box There are two pedals: gas and brake. You need to control the machine with only one foot, keeping it on the gas pedal. The other leg at this time should be to the left of the brake on a special stand. Otherwise, if there is a danger on the road and it is necessary to brake, you can press the gas pedal by inertia. To slow down on an automatic transmission, you need to take your foot off the gas and press the brake pedal.

How to drive a car with an automatic transmission

The automatic transmission has several modes.

When the lever is in position P, the drive wheels and the shaft are blocked. This mode is used when parking and long stops. Switch to parking only after a complete stop. To move the lever to this position, you need to hold the brake. If you turn on P while driving a car with an automatic, the car may break down.

If the car is parked on a relatively flat surface, then the use of the handbrake may not be necessary. If the slope is steep, then to relieve the load on the mechanisms of the car, you can additionally use the handbrake.

To put a car with an automatic machine in P mode with a handbrake, proceed as follows:

Press the brake, pull the handbrake;

Release the brake (in this case, the car may jerk a little);

Press the brake and put the lever in P.

To remove the handbrake, you need to switch the box to the drive mode, and then release the handbrake while holding the brake.

To turn on the reverse gear on a car with an automatic, you need to completely stop the car, and while holding the brake, move the gear lever to position R.

There is a lot of controversy among those who do not know how to ride properly about the N position.

This mode is used to move the machine over short distances, for example, in a service, with the engine running. Many people think that when coasting down a hill, you can save gas, including neutral, but this is not the case. Since at the end of the slope it is necessary to turn on the engine again, and this gives an additional load on the box. Also, you should not put the car in N during stops, for example, at traffic lights.

To drive at any speed, you need to use mode D.

By bad road or when towing the car, you can turn the box to position 2. This will prevent the car from shifting to a gear higher than second.

If you are going to accelerate the car to 80 km / h, then using a gear limit is not recommended.

If road conditions do not allow driving at a speed of more than 15 km / h, then you can turn on the L mode, then the car will only drive in first gear.

In machines with an automatic machine, there may be a special overdrive mode(O/D). If this button is depressed, then the car can switch to fourth gear. This mode is needed for driving on long climbs and overtaking when fast acceleration is needed.

On cars with automatic transmission there is also a kick-down mode. It turns on if there is a sharp press on the gas pedal. Thanks to this, the car accelerates sharply, however, when starting off, it is not recommended to use this function.

In SNOW mode, it is convenient to ride in winter. Thanks to this mode, the machine starts moving from the second speed, which reduces slippage.

Thus, drive an automatic simple enough. The key to this is practice.

Every driver should know how to use an automatic transmission, regardless of what car and with what shift option (manual or automatic) he drives. Situations in life can be different, maybe someone will soon have to change the car, and it has an automatic transmission. It doesn't take long to retrain, because mechanical way considered more difficult.

Using an automatic transmission is much easier than operating a manual transmission. Even, provided that the automatic transmission has a lot more functions. Consider all the possible modes and functions of cars with an automatic transmission. So, the main and additional modes and functions:

• P-Park - this mode indicates parking (parking). When this mode is enabled, the internal blocker is activated. This function plays the role parking brake. The vehicle is stationary.
• R-Reverse - reverse, a function responsible for moving the car backwards.
• N-Neutral - neutral gear (before choosing the direction of travel). In this mode, the car can also be towed. It is not recommended to use very often.
• D-Drive - when selected this provision on the wings, the vehicle will move forward. Drive mode can only be entered when the brake pedal is depressed (but not at high speeds). In this mode, blocking is provided.
• "4-3-2-L" modes are special modes that are provided for different roads with different coverage. Each of these modes uses a different number (number) of gears. Such regimes are various conditions movement. For example, you need to move through a mountainous area, where there are not particularly normal roads. For this condition, you can use the "L" mode. In this mode, the car will keep one assigned speed, while not going beyond these limits. Also, this mode can be used to lift the vehicle up, since in this position the thrust increases (closer to the maximum).
  
• Mode D3 (S) - a gear in which it is better to control the car on uneven surfaces, especially when going up and downhill. This makes the brake work better.
• D2 - the transmission is similar to the "L" position, since it is - downshift, which allows the car to overcome very steep slopes and climbs, it works especially well on sand and on ice.
• Steptronik, tiptronik (steptronic, parking sensors) - in these modes, it becomes possible to shift gears manually. This increases the control over the driving of the car for a particularly hazardous areas tracks. This mode is not provided in every system, but if it is present, it usually has a cutout and is indicated by "+" and "-".
  
• Sport or Kick down - in this mode, it is possible to spin more engine and thus it is possible to generate smaller speed. It is this mode that allows the car to accelerate sharply (often used when overtaking or advancing). In this mode, the engine runs at maximum. Cannot be used for everyday use.
• You can also find additional modes that cars are equipped with. These are: normal (N), sport (S) and environmental modes (E).
• Very often, the box has functions for the winter period in its arsenal. That is, there is also an operating mode for winter. This mode can be designated differently (HOLD, SNOW, WINTER), but this gear has the same meaning - it insures the car when it is driving on a road with ice, mud, snow, etc. It is forbidden to use this functionality during the warm periods of the year, as the box will constantly overheat.
  
• The Shift function is a button that provides a service call. It serves to complete shutdown power, it was possible to disable the lock lever of the automatic gearbox. Its use is extremely rare.

All (old and new) functions and modes of automatic transmission are described above, but the automotive industry does not stand still, experts are trying to come up with something new every day. Perhaps the automatic transmission will also undergo some changes in the future.

Terms of use

For someone who wants to learn how to use an automatic transmission and properly operate a vehicle with such a box, I will tell you the basic rules.

The main rule is that the use of slip is prohibited. The mechanical version does not tolerate various slips at all. This rule is quite relevant for driving in winter period when there is snow and ice on the roadway. Under such conditions, it is necessary to be extremely careful not to overload the operation of the box, and indeed the entire system. It is also not recommended to resort to slipping in the warm seasons.
Often modern cars equipped with automatic gearbox additional features such as anti slip. This feature must be turned off in situations where your vehicle is stuck. Such a maneuver will allow you to safely leave on a normal surface. Since it is impossible to completely disable this system, its performance can be minimized.

It is not recommended to switch to the neutral gear position while driving, without any special reason. This mode is mainly intended for driving in " service mode”, that is, in this position, you can only move when the engine is off (when towing). Otherwise, with frequent use of this mode, there may be undesirable consequences in the operation of the automatic transmission.

In addition to these rules, it is also necessary to remember that automatic view boxes are pretty complex mechanism, which requires timely diagnosis, warranty service and changing the transmission fluid. It is important to remember that service maintenance should be carried out strictly according to the schedule, this is especially true when driving on our roads.

Use in the winter: As a rule, special difficulties in driving, when the car has an automatic gearbox, arise precisely in the winter. Therefore, this time is considered the most dangerous for drivers. In order not to break under the influence weather conditions, you need to know what are the features of driving in the winter.

It should be remembered that in the case, the higher the load, the more allocation occurs. warm air in the hydrotransformer. Therefore, it is necessary to take some measures, provided that you often use the trailer. To provide normal operation you need to think about the option with an additional radiator, so that the box is additionally cooled. When towing a trailer for a long time, it is not advisable to use overdrive(tow at 2-3 speeds). Before using the trailer, keep in mind that the automatic transmission resource is developed faster when towing, that is, some elements of the system may become unusable very soon.

How not to use

There are some requirements and rules that warn drivers against improper operation of the vehicle on which the automatic transmission is installed.

Important to remember:

I wish you success in mastering a new type of vehicle control.

Video “The nuances of driving a car with automatic transmission”

The post will talk about correct use automatic transmission and about the opportunities that will open up for you while driving a car with automatic transmission. By watching the video, you will also learn a lot useful nuances associated with automatic transmission.

Now many newly minted motorists decide for themselves which car to choose. The most, perhaps, important criterion it's the choice of transmission - and as sales statistics tell us - automatic transmission is growing exponentially. It is understandable in the city is very convenient. However, on many automatic transmissions, there is a so-called “manual mode” when you change gears in a physical way, usually this is a plus and minus on the lever (made with a button like mine) or shifting the gear lever. BUT WHY is there a manual mode on the machine? Are we taking a fully automated process? Today will figure out...

To be honest, such a solution is correctly implemented - only on torque converters and on robots, that is, you physically shift gears, for example, such a solution is also present on the variator, but there it is a purely software feature, because the variator gearbox is stepless, that is, it has no physical transfers.

Oh well, in general - there is a presence on almost any automatic transmission, but for what ??? Such mechanical mode many are brain-teasing — it seems to be moving away from mechanics, but it is here again, it turns out “rubbish”!

It absolutely does not require special skills, it turns on - elementary. Personally, on my machine, it’s enough to move the lever to the “M” position, you will see a speed gradation on the instrument panel, “M1”, “M2”, “M3”, etc., for example, I have six steps, which means top gear "M6".

As for switching - you can do it as from a parking lot, that is, start off in manual control, or already at speed, transfer the box to mechanics and adjust as needed! It can be done this way and that, no matter, for the automatic transmission it does no harm.

Why is this mode useful?

To be honest, some time ago, there were no such manual modes! In 85% of cases, a simple driver does not experience any discomfort from this, you quickly get used to the machine and adapt, then you don’t even notice how it works. However, the mechanical mode is often simply necessary, one cannot do without it, let's list:

• Wheel slip or off-road.
• Slide.
• Speed.
• Gear braking and cornering.
• Traffic jams.

Yes, yes, you heard right for these points and the manual mode is important, that is, it gives you more possibilities than the "brain" of the machine. Of course, it is possible to pass all these obstacles on the automatic transmission, but some points are simply unsolvable for him, as we say the first one. Let's go into more detail.

Slipping or off-road

IN our snowy homeland - oh, how necessary. If you do not put the automatic transmission in manual mode, then as the speed increases, it will try to switch to more high gear, thereby "choking" itself. I myself personally encountered this, for example, you start to slip, the car seems to make its way through the snow a little - and it bangs into the second or third, there are not enough revolutions and the car gets up. This is where the mechanical mode helps, turned on strictly the first one and “fights” snowdrifts (drifts will be in the video below).

The situation is absolutely the same with mud, because in fact the movements in these two environments do not differ, and here and there we skid, the gears that we have chosen are important to us, that is, we think for ourselves.

Slide

Here, manual control is also pleasing - when driving from a protracted hill, you ease the pressure on the gas pedal, the machine will try to switch to a lower gear after some time, which will indirectly stop the car! You can manually leave the overdrive until the hill is completed. Thus, you save fuel, because turn on.

Speed

Not always modern machines, smart. That is, the pressure on the gas pedal is not always adequately perceived. What if you need to accelerate sharply, and the automatic transmission does not understand this, of course, now almost everyone has KIK DOWN, they pressed the pedal to the floor and the engine quickly “spun up”! But here's what to do - if you need to get around a large truck or trucks, and you need to leave the overdrive for a long time? This is where the manual mode will help, just “lower” to desired gear, at speed, let's say it is “5” or even “4”, and we press “gas to the floor”, after driving around the trucks, we switch to auto mode.

Gear braking and cornering

• A controversial plus, but worth noting - this, if you like, came to us from the "mechanics" when you switched from high to low and stop the car - let's say on slippery roads. After all, the wheels are not blocked, braking is more effective. On the machine, now you can also do this, for example, you drive in 6th gear - there are obstacles in front, in the distance, and the road is icy, the car does not adequately behave when you press the gas pedal. Just mechanically downshift and the car will get up, slowly and confidently, then bring it to a complete stop with the brake pedal. As I said, this method is controversial, because now there are a lot of sensors and systems (ABS, EBD, ESP, etc.) that will help stop the car without the participation of the box, but God saves the safe.

• This is cornering if you go on high speed, then it is worth transferring to a lower gear manually, and you no longer need to use the brake, the speed drops, the turn is completed.

As you understand, this item, nevertheless, is for lovers of freedom of action who are experimenting with the "automatic" at speeds.

Traffic jams

Also a controversial point, but I met on many forums.

Many people use manual mode for driving in traffic jams. "How?" - you ask. Yes, simply, the machine will always jump from first to second, respectively, fuel consumption will increase. In order to somehow reduce it, you can choose a “pure” second gear and use it to overcome the traffic jam! However, it is worth noting that acceleration should not be sharp, yet second gear is not for starting a car.

In fact, these are all advantages. manual mode automatic transmission, I personally noted for myself and constantly use it - when slipping and when driving downhill, the rest is not so important!

Now watch the video lesson.

This concludes, read our AUTOBLOG, there will be much more useful.
