What is the letter of the automatic transmission electronic brake

There are six gears on a general automatic car, from top to bottom: P, R, N, D, 2, L. P – Parking.

When you don't use the park, the gear is here, and the wheels are in a mechanical holding state to prevent slipping. R – Peverse Gear, reverse. Used when reversing.

n - none, neutral. Use this gear when stopping temporarily (e.g. at a red light). Note that this gear indicates neutral, and to prevent the vehicle from slipping on slopes, be sure to apply the brakes.

D - Forward gear, also known as drive gear. Needless to say, this gear is used when moving forward. 2 - low gear, when going up a large slope, or when starting on a relatively inclined slope, you can use this gear to start and move forward.

The principle is that by hanging the gear here, you can limit the gear of the car to automatically switch only in the low gear (equivalent to the first and second gears of the manual transmission car) to ensure that the car gets the maximum forward momentum. L-Low, low gear. When going downhill or down a long-distance slope, hang the gear here, which can limit the gear of the car to automatically only be in the lowest gear (equivalent to the first gear of the manual transmission car), which can make the car use engine power to brake when going downhill, and the driver does not need to step on the brakes for a long time to cause the brake pads to overheat and cause danger.

Generally, motor vehicles will have a handbrake! The electronic parking system is abbreviated as "EPB" is the abbreviation of electrical park brake, which is to put it bluntly, it is the electronic parking brake button that replaces the traditional trolley handbrake. It is safer than the traditional trolley handbrake and does not change the braking effect due to the driver's strength, turning the traditional trolley handbrake into a button within reach.

Hello, the electronic parking brake switch button is marked with a P word in the circle.

The automatic transmission model has the brake on the left, the accelerator on the right, and only two pedals.

The driving difficulty of automatic transmission cars is much lower than that of manual transmission, and the very friendly driving style has won the love of the majority of young people, especially for female drivers. Before starting the automatic transmission, you first need to know some basic car functions and buttons, among which the brake pedal on the left is the accelerator pedal on the right.

Precautions for automatic transmission brakes.

If you use the engine brake while driving on a long downhill section and use the brake for a long time, the braking system will heat up and affect the braking performance. Therefore, according to the road conditions, the transmission can be selected in 3rd gear, 2nd gear, L gear (automatic wave) or 3rd gear, 2nd gear, 1st gear (hand wave), and the engine brake can be used to control the speed of the vehicle without pressing the accelerator pedal.

In the case of good road conditions, such as a traffic light at the intersection ahead, the ideal braking state is that there is no impact on the passengers. To do this, you must first make a judgment based on the road conditions ahead. If the distance is sufficient, there is no need to apply the brakes first, so that the vehicle inertia can maintain low-speed coasting to save fuel economy; If it's not enough, start applying the brakes gently after the oil is drained and decelerate smoothly.

Left brake, right throttle.

Automatic transmission: Automatic transmission, as the name suggests, does not require the driver to manually change gears, and the vehicle will automatically select the appropriate gear according to the speed and traffic conditions. There are six gears on a typical automatic car, from top to bottom:

p、r、n、d、s、l。

Automatic Transmission Throttle Taboo:

It is not allowed to press the accelerator too hard while still on the brakes, or even before releasing the handbrake.

It is not allowed to press the throttle first and then shift the gear into P or N.

It is not allowed to move the gear pull while stepping on the accelerator.

Automatic Ignition Method:

When parking, you must put the P gear in gear and pull the handbrake. Parking here refers to parking for a longer period of time when a person may leave the vehicle.

The engine can only be ignited in two gears, P and N. And, because of the first point, when restarting after parking, it must be in P gear. Generally, the engine cannot be put on other gears before ignition.

The automatic car brake pedal is located on the left side of the accelerator pedal.

Here's a closer look at the automatic brakes:

Automatic models have brakes on the left and accelerator on the right, with only two pedals. You should brake in advance, be careful not to get too close to the car, keep a safe distance from the car, and brake in advance to anticipate the road conditions ahead. Long downhill braking should be assisted by engine braking, otherwise the brake pad temperature will be too high.

When braking in a corner, the vehicle should brake and slow down in advance before entering the corner, and then refuel after taxiing into the corner. Point braking should be used when braking in rainy weather or on sandy roads to avoid vehicle skidding.

Braking, also known as braking, refers to the action of stopping or reducing the speed of a moving locomotive, rolling stock, and other means of transport or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, and install the corresponding brake shoe, belt or disc on the base of the machine, so that it can generate braking torque under the action of external force. A braking device is also a mechanical braking device that can slow down the speed of a vehicle, also known as a reducer.

In the vast majority of emergency situations, the brakes are your best first choice. For cars traveling at high speeds, emergency braking is the safest option. If you choose to steer, it is likely to have serious consequences due to loss of control.

If you brake suddenly, you will take steering or other measures at the same time as the speed of the vehicle is reduced, which will greatly increase safety.

Automotive electronic parking brake system, abbreviated as EPB (electrical park brake), commonly known as automotive electronic brake, automatic parking, etc., the system shows us, is to replace the traditional trolley hand brake (hand brake) of the electronic hand brake button, safer than the traditional trolley hand brake, will not change the braking effect due to the driver's strength, the traditional trolley hand brake into a button at your fingertips. The microprocessor control module (ECU) comprehensively processes, and the longitudinal accelerometer sensor calculates the slope, so that the sliding force generated by gravity on the slope of the vehicle can be calculated, and the controller applies braking force to the rear wheel or four wheels through the servo motor to balance the sliding force, so that the vehicle can stop on the slope; When the vehicle starts, the controller calculates the braking force that needs to be applied through the displacement sensor on the clutch pedal and the displacement of the accelerator pedal, and at the same time obtains the information of engine torque and traction through the communication with the engine control module (ECU) through the bus (CAN), and the controller automatically calculates the increase of engine traction and reduces the braking force accordingly. When the traction force is sufficient to overcome the sliding force, the servo drive motor is instructed to release the brakes, so that the vehicle can start smoothly.

The system automatically realizes thermal compensation, if the car is parked after forced movement, the brake disc will produce a gap with the friction plate due to the temperature drop, and the servo motor will automatically drive the compression nut to compensate for the gap caused by the temperature drop to ensure a reliable parking effect. Different manufacturers and different models have different names and names, and the basic functions are the same; The function of the system is mainly reflected in the following three aspects: 1. In case of a short stop such as a red light during driving, the system will automatically brake the wheels after the vehicle is stopped to prevent rolling.

In this way, the driver does not always want to pull the hand brake (handbrake); When the light is green, press the accelerator pedal directly to start, and the system will automatically release the wheels. 2. When parking on the slope, the system will automatically brake to prevent the vehicle from sliding, and when the traction force of the start on the slope reaches the degree that it can go forward on the slope or is greater than the sliding force, the system will automatically release the brake wheels and move forward directly. 3. The parking lock does not need to pull the hand brake, and the system will automatically brake the wheels at this time.

However, the third function is not available in some models, and the car needs to be manually braked by hand, and the different functions of different models of manufacturers are slightly different. @2019

Automatic models have brakes on the left and accelerators on the right, with only two pedals; The manual transmission model has three pedals, with the clutch on the far left, the brake in the middle, and the accelerator on the far right.

About automatic transmissions:

Automatic transmission means that the driver does not need to change gears manually, but there will be a computer in the car to automatically help you shift gears according to road conditions and vehicle conditions. Generally, there are five gears on automatic transmission cars, the order is: P, R, N, D, S, and some cars also add manual mode to the automatic transmission, that is, manual gear change can be achieved without clutch, which adds a little driving fun.

Car braking tips.

1.Brake slowly, being careful not to brake suddenly, or the vehicle will nod its head.

2.Brake in advance, be careful not to get too close to the car, keep a certain safe distance when following the car, and brake in advance for the road conditions ahead.

3.Long downhill braking should be assisted by engine braking, otherwise the brake pad temperature will be too high.

5.Use "point brake" when braking in rainy weather or on gravel roads to avoid vehicle skidding.

1.The automatic transmission model has the brake on the left, the accelerator on the right, and only the plate; The manual transmission has the clutch and brake on the far left, and the throttle with a plate on the far right.

2.About automatic transmissions:

3.Automatic transmission is the driver's manual shift, but there will be a computer in the car that automatically shifts gears for you according to the road conditions and the source of the positive vehicle conditions. There are a total of 10 gears in the automatic transmission car, the order is P, R, N, D, S, and some cars also add a manual mode to the basic Hu Crack hand of the automatic transmission, that is, the clutch can realize the human gear, increasing the driving performance.

5.Slow down and pay attention to braking hard, otherwise the vehicle will nod its head.

6.Braking in advance, be careful not to get too close to the car, keep a safe distance when following the car, make a prediction of the road conditions ahead, and brake in advance.

7.As for long-term braking, you need to use engine brakes as an assist, otherwise there will be a problem of excessive brake pad temperature.

9.When braking in rainy weather or gravel roads, use "point braking" to avoid side skidding.

Summary. Hello car owner, the car automatically hooks into the n gear will not, but the automatic brake is there, this is called the brake assist function, for example, after you open this function, for example, when you are waiting for the traffic light to hang in the d gear, you can release the accelerator, the brake is released, the car will not go, when you step on the accelerator, the back of the handbrake can be automatically released, and then the car can go, which greatly relaxes the driver's feet.

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Hello owner, the car automatically hung into the n gear will not, Shantong but the automatic brake is there, this is called the brake assist function, for example, after you open this function, for example, when you are waiting for the traffic light to hang in the D gear, you can release the accelerator, the brake is loose, the car will not go, when you step on the accelerator, the back of the handbrake can be automatically released, and then the car can go, which greatly relaxes the driver's foot.

I was in the automatic car washing machine when the n automatic brake, there is no way to lift.

Do you mean that you can't lift it after you put n gear in the stupid calm car wash? You want to check whether the automatic car washing machine has allowed your liquid vertical car to enter the water when washing the car, resulting in a line fault with a rough burial.

The left side of the automatic transmission car is the brake. Whether it is a manual transmission or an automatic transmission, the only difference under the foot is whether there is a clutch or not, and the left foot position of the automatic transmission has no clutch, and the left foot is free. The brake is the same as the accelerator, the right is the accelerator and the left is the brake.

There are only two pedals for the accelerator and brake in the automatic transmission, of which the left is the brake and the right is the accelerator, and this order must be remembered. Start by pressing the brake pedal on the left before starting the car.

Left brake, right throttle.
