Sports mode in the car. How to use an automatic transmission correctly. Driving on the highway

The active development of the automotive industry continues today thanks to the introduction the latest technologies in the industry. The manufacturer invests a large margin in modern cars in terms of dynamic and power characteristics, improves the level of equipment, safety, etc.

At the same time, a lot can depend on the quality of the implementation of a particular technical solution, including the life and health of the driver, passengers, and other road users.

Note that taking into account the great popularity, the "S" (Sport) mode is designed to fully feel the "drive" from driving. Also, this mode is able to help the driver in a difficult situation. In this article we will look at what "S" transmission is on the machine, why this mode is needed and how to use it.

Automatic transmission modes

Let's start with what the automatic transmission has. The main and lowering modes include:

Drive "D" (movement) - the movement of the car, the box automatically selects the necessary gear.
Reverse "R" ( reverse) - movement of the car backward.
Parking "P" (parking) - blocking of the output shaft and, accordingly, of the driving wheels (the selector can only be moved after a complete stop of the car, remembering to turn on the handbrake).
Neutral "N" - idle operation of the engine (it is recommended to turn on the mode only during long stops).

Reducing modes include:

"3" - the automatic transmission works only in the first three gears.
"2" - the automatic transmission works only in the first two gears.
"1" or "L" - the movement of the car only in the first gear.

We add that until recently, most drivers were extremely skeptical of cars equipped with automatic transmissions. Many believed and still believe that the automatic machine does not allow you to fully control the process of driving.

It is in order to change the algorithm of work in conjunction with automatic transmission and to make it sharper, faster, responsive, etc., manufacturers began to actively use it, added the "Sport" function (S, automatic transmission sport mode).

Mode "S" on the machine: what it means and what is it for

In modern automatic transmissions, in addition to the main and lowering modes of operation, there are also additional ones, the use of which depends on the operating conditions of the car, driving style, etc. The modes are switched on through the software commands prescribed in.

One of these modes is "S", "Power" or "PWR" (sports) mode. The S position on the automatic transmission can be different - in one case, this solution is implemented by means of a button, in the other case, by means of an additional position.

In Sport mode, upshifts are carried out at maximum engine speed. Compared to normal driving, when the "S" mode is turned on, the driver will be able to feel the difference, the car begins to react faster to pressing the accelerator pedal, picks up speed more intensively, on many cars steering becomes "sharp".

Driving in Sport mode is maximized by the Stability Control (ESP). It allows the minimum controlled drift of the car axle, allowing the driver to feel like driving a sports car.

At the same time, the exchange rate stability system, although it allows you to drive the car more aggressively, is nothing more. In other words, the complete safety of the driver and vehicle no electronics is capable of providing.

Some manufacturers, making it as easy as possible to drive a car, install an adaptive system that adjusts to the driver. The system recognizes up to ten predicted situations:

uniform movement along the highway,
acceleration, acceleration or braking on a bend, etc .;

Depending on the current situation, if the driver did not make adjustments to the ECU operation algorithm in time, the system will automatically turn on or off the sport mode.

Where and when to use "S" transmission on the machine

The sport mode is especially indispensable outside the city with an active change of the speed mode. Sometimes it is used while driving in city traffic.

Let's summarize

The presence of the "S" (sport) mode in cars equipped with automatic transmissions will allow many fans of active drive to transfer their views from to automatic. In this case, the owner gets a double benefit.

The first is the ease of driving a vehicle with automatic transmission in everyday modes, and the second is the ability to get the most out of the engine and gearbox when necessary, as well as experience the pleasure of extreme driving.

Auxiliary modes

Modern cars use assisted modes for an automatic transmission. Most often, their switching is carried out using an additional rotator on the instrument panel or closer to the RVD, which is fixed in one of the preset positions.

"N" - normal driving mode. Used for normal non-extreme control.

"E" - economy mode. Used for smooth gear changes and while driving.

"S" - sport mode. While driving in this mode, the automatics use the maximum power characteristics of the car. Thanks to such operation, faster switching between stages is carried out, acceleration is accelerated. Consumables fuel characteristics rise significantly.

"W" - winter mode operation is in demand during the start at slippery road... The beginning of the movement usually occurs from the second gear.

It is also necessary to clarify that the owners of automatic transmissions who have moved from the "mechanics" are offered a complete set of transmissions with the possibility of an independent manual mode of gear shifting. This feature first appeared on Porsche vehicles and is now called Tiptronic.

Subsequently, this name was picked up by car owners, and it became a household name for all such nodes. For self-switching, the lever is moved to the zone limited by "+" and "-". Paddle shifters can also be used.

Car operation with automatic transmission

Before starting the movement, squeeze the brake all the way. Next, you need to move the lever from the set "neutral" or "parking" to the "Forward" or "Backward" zone and lower the handbrake. The brake is released smoothly with the right foot, and the car smoothly begins to drive. You need to accelerate the car with smooth pressing of the right foot on the accelerator pedal.

You need to know that only the right leg is involved in controlling the pedals of a car with an automatic transmission, and the left one stands in the place reserved for it.

In order for the car to gradually slow down, the driver must slowly raise the foot, returning the pedal to the upper position. During this process, the gearbox will shift gears down. You can speed up the process by pressing the brake pedal.

It is also possible to re-move from a place without additional switching of the handle, only by pressing the gas pedal. It turns out that it is enough to turn on the "D" mode, and adjust the speed with both pedals.

Important! When driving a car with automatic transmission, it is necessary to avoid sudden changes in speed, because such operation causes significant wear on the transmission.

Improper use of the "automatic" will unbalance the work of the clutches, increasing the distance between the discs. This leads to the fact that the car begins to twitch during the gear change.

Automatic transmission operation in winter

The most problematic time of operation of the "machine" is considered the period with icy and snowy road surface. This happens for several reasons:

slipping while starting to move on a slippery surface, if the car is stuck;
subzero temperatures negatively affect the operation and resource of the automatic transmission.

It will be possible to reduce the negative impact on performance if you adhere to some rules.

Visual inspection is carried out ATF oils... In the presence of significant darkening or metal inclusions in the liquid, it is imperative to replace it. When the vehicle's mileage on one ATF reaches 30 thousand km, then it also needs to be replaced.

During freezing temperatures and, especially, open storage of the car, it will be necessary to warm up the engine before driving.

You need to know that in the working temperature regime A car with an automatic transmission leaves in 5-8 minutes at an ambient temperature of -20 C.

If the car has additional modes "D1", "D2" or "D3", then it is better to start driving in winter with "D1", depressing the pedal by a third or half of the stroke, and after 100 meters, increase the gear.

In the presence of auxiliary winter modes such as "SNOW", "*", "W", "WINTER", "HOLD", it is worth activating them with the help of the additional rotator or buttons.

The stuck car must be removed from the snowdrifts on their own using reduced modes. If there are none, then you do not need to abuse the "swing method" for a long time.

Slippery roads lead to drifts. To maintain control of the car, you must not release the accelerator pedal, this applies to front-wheel drive cars. To enter corners, you will need to switch to lower stages so as not to drop rpm and power.

Undesirable actions

Do not overload a car with automatic transmission if it is not yet well warmed up. This also applies to the warm season, during the start of the movement, you must observe a moderate speed limit without jerks and sudden changes in speed.

"Automatic" does not like off-road and possible slippage. Also, do not install trailers on vehicles with automatic transmission in order to reduce wear on the unit. It is not advisable to start the car by pushing when the battery is dead.

Winter mode "automatic" Depending on the manufacturer, it can have different markings: Winter, icon * , Snow, W etc. The main purpose of the winter mode is to minimize slipping, for which activation of the first gear is excluded. For the start, the second stage is used, which allows for a more smooth transmission of torque to the wheels, which is very important on slippery surfaces. Any gear change takes place at a reduced engine speed, thereby ensuring smooth operation of the gearbox and almost completely eliminating the possibility of a skid. When the ambient temperature is warm, it is strictly forbidden to activate this algorithm.

First of all, it should be remembered that automatic transmissions do not like sharp accelerations and prolonged wheel slip - this leads to their overheating of the "automatic machines". If it is impossible to move in any direction, do not feverishly move the wings in the selector groove, but it is better to seek outside help and push or tow the car. The general process of driving a car and using the automatic transmission is as follows. To start using the automatic box you need:

Parking mode automatic transmission

To begin with, I want to say right away to those who assure us that you cannot put on this mode in the parking lot! Guys, that's not true. The word "Parking" is originally English, if translated, it means - "parking". Thus, manufacturers hint that when you stop, you need to turn on this particular mode. It's kind of putting the car in gear when compared to mechanics.

Physically, this is implemented as follows - a special lock washer is put on the working gear of the automatic transmission, from one end it is put on a special lock washer (it sits rigidly on the gear), it is made by protrusions or "teeth", when "parking" a special lever enters it, which stops these teeth - blocking the gear ...

How to use an automatic transmission correctly

Automatic transmissions are divided into hydraulic and electronic (depending on the type of control). Please note that if the automatic transmission does not have additional buttons (such as PWR, SNOW, OD), this is a conventional hydraulic box. Otherwise, you are dealing with an electronic hydraulic design.

Automatic transmission provides automatic selection gear ratio suitable for the riding conditions. Due to this, the driver does not need to make unnecessary movements. Despite the ease of use of an automatic transmission, there are some important nuances of its operation. Every driver should know about them. First, let's take a look at the types and operating modes of the automatic transmission.

How to use automatic transmission? Operating modes, Management

The mechanical part of such a box is indistinguishable from a conventional automatic box, only the automatic control and the selector lever have been changed. Such automatic transmissions are characterized by a cutout for moving the selector lever in the form of the letter H, and the symbols, +, and, -,. Nevertheless, such a mode (AUTOSTICK) is more semi-automatic than manual, since the transmission computer monitors the driver's activity and will not allow him to select a gear exceeding the permissible engine speed or will not let him start from top gear. The rest gives the impression of using a manual gearbox. If such a desire arises, then you can easily return to the normal automatic transmission mode by putting the speed mode switch in position D, so rather it driving on automatic transmission rather than "poking" with a pen.

In the automatic gearboxes of later models, where there are more operating ranges, there are additional modes of operation. In the automatic transmission control system, they are present in the form of switch buttons. An experienced driver knows how to use automatic transmission modes so let's go over it ourselves.

How to use automatic transmission correctly

"D2"- "automatic" operates in the interval of two gears. Often this lever position creates comfortable operation when traveling at speeds below 50 km / h. Drivers are advised to drive it on forest roads, mountain serpentines, on snow-covered road surfaces when a low speed is required.

Automatic transmission sport mode

PWR mode is a sport (active) mode, activation occurs using a button near the selector. Another, in other words, is the active driving mode. In this mode, in comparison with the D mode, there are differences: switching to the next gear will occur when more high revs(provided that the gas pedal is at the same level).

Mode 2 is the driving mode in low gears. The car starts moving from the first gear, then the movement continues only in the second gear (not higher). At higher speeds, switching simply does not occur. Compared with mode D, then, in mode 2, the torque converter is made more rigid, namely, the connection between the wheel and the engine is more rigid.

Automatic transmission

For example, the variator has no shifting 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 diameter of the shafts, which changes the output speed without power loss and jerks. The robot, on the other hand, is essentially a high-quality manual transmission with an effective electronic control... Lovers of mechanics can always switch to their favorite mode.

torque converter. Represents the evolution of a clutch developed back in 1903. The place where torque is transmitted from the engine to the output shaft. The principle is simple. A pumping turbine connected to the engine propels 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.... This does not transform the torque. It provides an additional element called the 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 changing the gear ratio;
planetary reductor. The main part of the automatic transmission. A complex mechanism assembled from a central or sun gear, a crown or large central gear and a set of satellites attached to a part called a carrier. By changing the position of the individual elements of the automatic transmission along the axis, several combinations are formed, transmitting several speeds of rotation of the central shaft at the output. The number of options is called transfers.... Direct analogue with manual transmission, but the circuit does not need a clutch, the function of which is performed by a fluid coupling. Such a system requires precise and complex control. It is impossible to provide effective 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 an electronically controlled automatic transmission. In the first case, the sensors, reacting to a change in the oil pressure in the system, activate the hydraulic pushers. They activate a complex combination of clutches and brakes by mechanically changing gears. The system is configured in such a way that it is impossible to "jump" over the transmission. Switching is only possible sequential. The electronic control system is more efficient. Sensors collect more complete information about the operation of the automatic transmission. This is both the temperature of the liquid and the rotational speed of each axis. The control unit gives a signal to the actuators. The operation algorithm of a whole group of parts at once is under the control of electronics. Clutches, brakes, and solenoids, often referred to as solenoids, are almost constantly in motion while driving;
selector lever. This is the "handle" in the cabin. All over the world, the marking of 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 luxury and executive cars provide the switching unit with additional positions. For example, Tiptronic has the ability to switch from automatic mode to mechanical control of the gearbox.

How to use an automatic transmission

The basic rule of using automatic transmission is to avoid sudden maneuvers. If you constantly do them, this will lead to an increase in the gap between the friction discs, and then in the differential. All this will lead to the fact that the car will jerk during each gear change.

Today, most drivers have no idea how they would drive a car that does not have an automatic transmission. Some newbies are horrified at the thought of having to constantly change gears manually. Many experienced drivers have also realized long ago that driving with an automatic transmission is much more convenient. Despite all this, people are tormented by the question - how to properly operate the automatic transmission? In this article, this is exactly what will be discussed.

How does an automatic transmission work: the principle of operation of an automatic transmission

The automatic transmission is a mechanical component that automatically changes the gear ratio without the need for intervention from the driver. This device transfers power to the wheels of the vehicle, allowing the engine to operate in a more productive range.

With the help of computer sensors, the car determines when to change the speed mode and gives a signal to engage or disengage the appropriate gear. The beauty of the automatic gearbox is the ability to change the acceleration using a small package of friction discs.

2) Let it warm up a little (it is advisable that the revolutions on the XX fall to 750. It is possible earlier, but then try not to drown the gas pedal before the temperature indicator reaches the operating range and generally keep the speed around 1500. The heat exchanger for the automatic transmission and the engine is common, so their temperatures are practically the same.)

Use the manual mode at your discretion. To do this, from position D, you move the selector to the side, there is an indicator of the current gear on the tidy. Well, then "+" - transfer up, "-" - transfer down. Do not be afraid to burn the box - the brains do not turn off in manual mode, in critical modes it will switch itself. But the need for manual mode in everyday driving is practically nil.

It's hard to imagine now modern car not equipped. However, not all modern drivers know how to use this unit correctly. They do not turn on the winter automatic transmission mode in cold weather and use other modes not in accordance with the needs of the car. The consequences of this are very dire - the automatic transmission may break.

The automatic transmission provides automatic selection of the gear ratio that matches the driving conditions. Due to this, the driver does not need to make unnecessary movements. Despite the ease of use, there are some important nuances of its operation. Every driver should know about them. First, let's take a look at the types and operating modes of the automatic transmission.

Types of automatic transmission

Depending on the number of gears, the units are divided into three- and four-stage. The latter have an additional mode called Over-drive. A 4-speed gearbox can be used as a 3-speed gearbox if the OD is switched off.

Modes of operation of the automatic box

There are those that differ from each other in design features. However, the main operating modes of the automatic transmission are present on all such units. Depending on the manufacturer, their designations may differ, but the essence is the same. Main modes:

Parking (P)- allows you to start the engine (can only be used after stopping the movement of the car and turning on the hand brake).
Movement (D)- activates the movement of the machine, automatically selecting the required gear.
Reverse (R)- activates the movement of the car backward (can be turned on only after stopping and by pressing the brake pedal).
Neutral (N)- provides idle work engine (can not be turned on while driving, applies to).
D3- used to downshift (must be started on small descents or ascents).
D2 (L)- also used for downshifting (used for heavy road conditions- on ice, mountain serpentine and so on).

Rules for operating the gearbox in accordance with the modes used

To use automatic transmission correctly, you must follow certain rules when using a particular mode:

Parking... Stopping on steep ascents or descents, you should use the "handbrake" to reduce the load on the elements of the parking mechanism. You need to tighten the handbrake before setting the mode, and remove it after switching the selector to another position. It is possible to switch from "parking" only if the button on the lever is pressed and the brake pedal is depressed.
Reverse... You can not move the selector to this position in the process of moving forward. Otherwise, the transmission or its individual components may break down. It is possible to engage reverse gear only when the lever button is pressed and the brake pedal is depressed. After choosing this mode, do not start driving immediately. Wait a second until you feel the jolt of the automatic transmission.
Neutral. Do not move the selector to the "neutral" position if the car is moving by inertia. You cannot turn on neutral if you are standing at a traffic light. Transfer the car to this mode only if you need to move it freely, and so that it works at the same time. For example, neutral is ideal if the car is being repaired.
D. This mode should be used under normal driving conditions. When switching to D from P / R mode, it is recommended to press the brake and the lever button and wait 1 second until the automatic transmission is turned on. Only then can you start moving. Maximum speed can only be developed when the lever is on the D button.
2. The mode is recommended to be used when driving on poor quality roads, as well as on frequently alternating descents and ascents. With frequent braking, this mode saves fuel. Do not turn on the "two" if the car is moving at a speed of more than 80-100 kilometers per hour (depending on the type of transmission). Do not switch to mode from position D if the driving speed is more than 80-100 kilometers per hour.
L. Can only be used when climbing stairs, driving into a garage, and so on. It cannot be turned on without pressing the lever button, when starting it, you cannot drive at high speed.

Using additional modes

Additional modes make it possible to use the capabilities more widely. They are used depending on the road surface, the mood of the motorist, the situation on the road. As a rule, they are implemented using electronics that control hydraulic system unit.

There are three main additional modes. These are NORM (or ECON), PWR (or SPORT), SNOW (or WINTER). It is very important to use each of them for their intended purpose.

NORM

Provides minimal gas mileage when driving. Gear shifting is carried out at medium engine speeds. At the same time, the car moves calmly and smoothly.

PWR

Uses engine power to the maximum. In this regard, upshifts are carried out at maximum revs. Due to this, the car accelerates with high acceleration. The "sport" automatic transmission mode is used with the appropriate driving style.

SNOW

Designed to facilitate movement in winter period... Due to it, the start-up of the car is carried out from the second gear. In addition, it allows you to easily navigate hard-surface slides or asphalt elevations. Effective when driving on wet grass. In cold weather, this mode will work effectively only if you combine it with high-quality winter tires.

Manual mode

Basically, the manual automatic transmission mode is used when driving off-road, in the mountains or when overtaking. When it starts, the driver independently changes gears. For its operation, it is necessary that it be equipped with electronic system management.

The video shows the use of automatic transmission in manual mode:

Manual control is carried out by electronic pulses. In this position of the selector, the gearbox can "adapt" to the driving style of the motorist. Not all manual transmissions are equipped with the SNOW function.

If the transmission is in emergency mode

If the transmission is used incorrectly, it can go into the so-called emergency mode Automatic transmission. The self-monitoring system of an automatic transmission allows detecting violations of its operation without the intervention of a motorist. The car will notify the driver of the transition to the emergency gang using a special indicator on the dashboard.

The causes of automatic transmission malfunctions may be:

electronics malfunction;
inconsistency of the amount of oil in the box with the one required in the instructions;
mechanical problems.

In order to avoid damage to the automatic transmission, carefully study the modes of its operation. Learn to use them correctly depending on the traffic conditions and road surface. Then your automatic transmission will last a long time and without failures.
