Will pulling the electronic parking brake hurt the car while driving?

Pulling the electronic handbrake while driving can cause damage to the vehicle's braking system.

For vehicles equipped with electronic parking brakes, when the electronic parking brake is pulled up during driving, in addition to activating the electronic parking brake function and having an alarm prompt on the dashboard, the vehicle will not flick its tail and roll over. When the electronic parking brake is continuously pulled, the vehicle will naturally slow down and stop without changing its driving trajectory, but it is not recommended to use the electronic parking brake to brake frequently.

As a vehicle equipped with an electronic parking brake, when the electronic parking brake is pulled during driving, the wheels will not lock directly due to the sudden braking due to the automatic intervention of ABS. And when the driver keeps pulling the electronic parking brake and does not let go, it is equivalent to stepping on the brake all the time, although the speed drop is more linear, but there is still a danger.

Imagine that the car is driving on the highway, suddenly pull up the electronic handbrake brake, its braking effect is much stronger than the foot brake, at this time this unsafe operation, it is very easy to bring the brake to the rear car is not urgent and cause a rear-end accident, it is not a good thing for yourself and others!

Manual transmission models

When equipped with a common mechanical handbrake, when the handbrake is pulled during driving, the car will have a tail-flicking phenomenon, which will cause the vehicle to lose control and roll over in serious cases. The reason is very easy to understand, mainly after pulling the handbrake, the rear wheels of the car will lock up, so that the vehicle does not have a linear deceleration and causes an accident.

If you are not a professional driver, you will not be able to control the steering wheel of the vehicle, which means that when the foot brake fails, you should not quickly pull up the vehicle's handbrake.

A normal car with a sharp pull on the handbrake does not stop the car at all, it only reduces the speed of the car. Many car owners believe that in high-speed driving or sharp turns, in the event of a sudden crisis, you can directly pull the handbrake to slow down, in an emergency, the handbrake can replace the foot brake, so that the car immediately stops moving forward, in fact, this approach is wrong and very dangerous. If the owner pulls the handbrake at high speed, it will be easy to lock the rear wheels, the cable will be broken, and the phenomenon of side slip and rollover will occur.

At the same time, when driving in sharp turns or rain, ice and snow, do not use the handbrake in a hurry, otherwise the ABS system will fail, and the rear wheel has no speed signal at all, which is prone to deviation and tail flicking. 1. The professional name of the handbrake is the auxiliary brake, which is different from the principle of the brake, which is connected to the rear brake shoe by using a steel wire to brake the car. Long-term use of the handbrake will cause plastic deformation of the wire, and since this deformation is irreversible, long-term use will reduce the utility, and the travel of the handbrake will also increase.

The handbrake is complemented by a recovery spring. When the handbrake is pulled up, the spring is elongated; The handbrake is released, and the spring returns to its original length. When the handbrake is used for a long time, the spring will also deform accordingly.

Second, the working principle of the handbrake for small cars, there is a brake disc after the gearbox, and the transmission shaft is connected to the place, similar to the disc brake (of course, there are also drum types), and then through the steel cable, the pull force is transmitted there, so as to achieve the parking brake. After pulling the handbrake, it uses a hydraulic auxiliary cylinder to push the hydraulic cylinder under the car to move, and then drive the air valve, (the reason why it is so designed is that the cab does not hear the sound of those air), and then after the air valve action, brake the transmission shaft, the car only brakes the transmission shaft with the handbrake, when the brake transmission shaft is completed, if it is an ordinary truck, the steel cable of the handbrake lever is used to pull and pull to achieve long-term braking, if it is a relatively high-end truck, such as Volvo's, then use electric control, Above, when you push the handbrake, there is actually an electric tractor that has been activated, and after the air braking is completed, it pulls the steel cable close and locks, of course, there is also a direct pull of the brake. 3. Precautions Handbrake is a system with a high usage rate, reasonable and correct use can make the future use smoother, especially for the largest number of mechanical handbrakes, better in accordance with the correct way to use, don't pull up the handbrake before the car stops, this practice is really not necessary.

It is important for safety to save some use and ensure good use effect, and it can also extend its adjustment cycle and reduce the cost of maintenance and replacement.

Pulling the electronic handbrake while driving will cause a lot of damage to the vehicle's braking system, so it is best not to try the emergency braking function at random in non-emergency situations.

1. Pull the electronic handbrake at a speed below 8km h, and the vehicle will stop;

2. When the speed exceeds 8km h, pull the electronic parking brake, and the instrument will light up the warning light but will not stop;

3. When the speed exceeds 8km h, keep holding the electronic handbrake, then the vehicle will start braking and finally stop.

Many models equipped with electronic parking brakes use this control method to avoid accidental touches or to cope with the failure of the foot brake. Therefore, when the electronic handbrake is pulled during low-speed driving, the vehicle will stop; Pull the electronic handbrake at high speed, pull it will give a warning prompt to prevent accidental touch, and pull it all the time to activate the emergency brake to stop the vehicle.

What happens when the electronic parking brake is pulled on while the vehicle is moving?

Hello, if it's an electronic handbrake, it's not a big problem. If the electronic parking brake is pulled by mistake, the system will default to the incorrect operation and will not brake.

It will damage the tires and braking system of the local car, especially the friction between the brake disc and brake pads, and reduce the service life of the brake disc and brake pads. However, some vehicles will be equipped with anti-mistouch power tong shielding energy, when the speed of the vehicle is greater than 8km h, pull the electronic handbrake Shihong will not brake the vehicle, only continue to pull the electronic handbrake The vehicle will stop, so accidentally pulling the handbrake when driving will not hurt the vehicle.

The electronic handbrake will not play any role in the process of driving, and some vehicles have two modes of electronic handbrake, one is the parking function, and the other is automatic parking, that is, when waiting for the red light, the vehicle will automatically pull up the handbrake, and when you step on the accelerator lightly, the handbrake will be automatically lifted.

Accidental touch of the electronic parking brake will not affect safety. Usually only the car is felt to emit it"Sudden protrusions"The sound, the body shakes very little and does not have the consequences of flipping or even rolling dangerously like a mechanical handbrake.

Hello car owner, the electronic handbrake will not play any role in the process of driving, some vehicles have two modes of electronic handbrake, one is the parking function, the other is automatic parking, that is, when waiting for the red light, the vehicle will automatically pull up the handbrake, and when you step on the accelerator lightly, the handbrake will be automatically lifted! I hope it can help you and I wish you a happy life. If it helps you, please adopt.

Hello, I need to confirm the car model.

Pulling the electronic parking brake while driving will hurt the car. The electronic handbrake system is equipped with an automatic protection function, and the handbrake is not released when it starts, and when the speed reaches a certain value, the electronic handbrake will be automatically lifted, so it will not cause any harm to the vehicle if the handbrake is not lifted.

Electronic parking brake is a technology that realizes parking brake by electronic control. Its working principle is the same as that of the mechanical handbrake, which is to control the parking brake through the friction generated by the brake disc and the brake pads, but the control mode has changed from the previous mechanical handbrake lever to an electronic button.

The principle of the electronic parking brake for automobiles:

1. Electronic parking brake is also an electronic parking brake system, and the electronic parking brake system (EPB: electricalparkbrake) refers to the technology that integrates the temporary braking in the driving process and the long-term braking function after parking, and realizes the parking brake by electronic control. The EPB system is manually operated by electronic buttons and is automatically controlled.

2. The electronic parking brake system is composed of the left and right rear brake calipers and the electronic control unit equipped with a planetary deceleration mechanism and a motor, and the electronic control unit of the system communicates with the vehicle controller local area network (CAN) to control the motor on the left and right rear calipers.

3. When the parking brake is required, the EPB button is pressed, and the button operation signal is fed back to the electronic control unit, and the electric control unit controls the motor and the planetary reduction gear mechanism to work, and brakes the left and right rear brake calipers.

4. There are two commonly used automatic control functions. One is that after the engine is turned off, the system controls the motor jointly with the electronic control unit of the vehicle CAN and the system to brake the left and right rear brake calipers. The other is the slope to drive away, on the slope, when the vehicle starts, the EPB electronic control unit controls the left and right rear wheel brake calipers to make them automatically release, and the vehicle automatically drives away.

Pulling up the electronic parking brake while driving will hurt the car, especially the wear and tear of the brake pads, which may cause the brake pads to break in serious cases. The electronic handbrake is to create friction between the brake disc and the brake pads, so as to have the effect of emergency braking, if the handbrake is pulled up to drive the vehicle forcibly, the brake disc and brake pads rotate, resulting in huge friction, which will cause damage to the braking system.

How to use the electronic parking brake correctly

1. Start the electronic parking brake. After stopping the vehicle, release the brake to find the button of the electronic parking brake, and gently break the button upwards to feel whether there is a brake sensation on the sole of your foot. If the electronic parking brake is working normally, the indicator light will also light up accordingly, if it does not work, consider whether there is a problem with the battery.

2. Turn off the electronic parking brake. Turning off the electronic parking brake is generally used before driving, and pressing the button of the electronic parking brake while lightly pressing the brake will also have a significant feeling of loose brakes under your feet. When the indicator light of the electronic parking brake is off, you can step on the brake and leave the gear.

3. Emergency braking method. In high-speed situations, it is best not to use electronic brakes for emergency braking, which is generally only suitable for slow speeds. When you need to brake suddenly, press and hold the electronic brake button for two seconds, but not every car has the handbrake emergency braking function.

Summary. There will be no direct damage to the vehicle, but pulling the electronic parking brake may affect the vehicle's handling. Some vehicles are equipped with a traction control system, which interrupts the connection between the tow wheel and the wheel when the handbrake is forced, resulting in impaired vehicle handling.

In addition, pulling the electronic parking brake will also cause the vehicle to be rented, thus increasing the risk of accidents. Therefore, try to avoid pulling the handbrake strongly while driving, so as not to cause damage to the vehicle.

Sorry I don't understand, can you elaborate on that?

There will be no direct damage to the vehicle, but pulling the electronic parking brake may affect the vehicle's handling. Some vehicles are equipped with traction control, and when the handbrake is forcefully pulled, the towing wheel will be disconnected from the wheel, resulting in a negative impact on the vehicle's handling performance. In addition, pulling the electronic parking brake will also cause the vehicle to be rented, thus increasing the risk of accidents.

Therefore, try to avoid pulling the handbrake strongly while driving, so as not to cause damage to the vehicle.
