What's the difference between electronic handbrake and ordinary handbrake? When starting automatically, the electronic parking brake must be released manually. It is not excluded that some high-profile models can be automatically released by ECU to judge the depth of accelerator pedal. However, compared with most brands of electronic parking brakes on the market, they are all released manually!

Different from mechanical parking brake, electronic parking brake can be used at any time, while mechanical parking brake is very dangerous when driving at high speed, and electronic parking brake has no hidden dangers when driving! This feeling! EPB and ESP can form a relatively complete system, and the car with ESP may not have this EPB.

But cars equipped with EPB must be equipped with ESP. They are good friends! According to different technologies, automatic parking brake can be divided into electronic parking brake by wire and electronic parking brake with integrated pliers. The first one consists of control button (P key), pull rope similar to ordinary hand brake, braking mechanism and return spring.

When in use, the driver presses the P key, and the motor applies the pulling force instead of manually pulling the rope, so as to tighten the brake pad and hold the brake disc to achieve the purpose of braking. If you stop for a short time, such as waiting for a traffic light, the manual release of the handbrake depends on the vehicle configuration.

If the vehicle does not stop automatically, the driver must release the parking brake manually, and then release the parking brake manually when restarting. If there is an automatic parking setting, the parking brake will start and release automatically as long as the brake is depressed deeply after opening.

When starting again, just touch the throttle and the parking brake will be released automatically, without manual release, making it easier to start. It can be seen that although the electronic parking brake has the word "electronic", the manual release of the brake before driving depends on the setting. Due to the different configuration of each car, it is recommended to read more vehicle manuals.

However, for the comfort of driving, I suggest not to let the automatic refueling release become the normal state, because the automatic release needs power to operate, so once released, the car will run very fast by power and driving comfort, and the elderly and children will not like this feeling, and the manual release will be smoother.

In addition, it is worth noting that the electronic parking brake cannot be released electrically under special circumstances when the vehicle cannot be started, but there are reasons to do so, such as traction. At this time, the parking brake needs to be released manually. Follow the instructions to find the place where the emergency unlocking is forced to open the cover, and there will be a forced unlocking device.

There are still potential safety hazards when vehicles slip downhill; If a strong man pulls the handbrake harder and then a weak woman wants to drive, it may be difficult to release the handbrake. Electronic parking brake only uses electronic components to realize parking, and parking brake can be completed by pressing a button.

In addition, most electronic parking brakes will be released automatically after stepping on the accelerator, and there is no need to cancel the parking brake manually, which also avoids the damage to the vehicle caused by the driver forgetting to step on the accelerator. Release the parking brake. Once the electronic handbrake breaks down, the owner often can't handle it by himself, because its structure is electronic equipment, once a component is damaged. It will cause irreversible damage to the whole parking system. When there is a serious power failure or no power at all, most cars cannot operate the electronic parking brake. Compared with cheap mechanical parking brake, it will be more complicated to replace electronic parking brake with more control modules and actuator motors. In the event of failure or damage, the maintenance cost will naturally be higher.

Advantages of ordinary handbrake: Unlike the traditional lever handbrake, the electronic handbrake will automatically unlock, and when you control the vehicle to move forward or backward, the brake caliper will automatically release. As long as the wear of brake pads is within the normal range, the locking effect of electronic parking brake is basically the same as that of lever handle.

Many cars equipped with electronic parking brakes often have hillhold function, which can slide uphill, and the slope is maintained by electronic parking brakes, which is a bit like the relationship between ESP and ABS. When the mechanical parking brake stops and starts, there is no need to pull the brake lever up and down.

In addition, the mechanical brakes on some cars are difficult to pull, and it will be very difficult for girls with little strength to use them. Especially when parking on uphill and downhill sections, if the parking brake is not set, the car is likely to slide downhill, which poses a safety hazard.
