Why don't some automatic cars have handbrake?

No matter what kind of car has a handbrake, there are two kinds of handbrake. The traditional mechanical hand brake is now used in ordinary cars, but some are pulled by cars, some are stepped on by the left foot, and some are electronic hand brakes that are just a button, and the principle is the same as the former.

1. Electronic handbrake is a technology to realize parking braking through electronic control. Its working principle is the same as that of the manipulator brake. The parking brake is controlled by the friction between the brake disc and the brake pad, but the control mode is changed from the previous manipulator brake lever to the electronic button.

2. The working principle of the electronic parking system is the same as that of the manual mechanical parking brake system. Parking is realized by the friction clamping between the brake shoe and the brake hub or between the friction plate and the brake disc, but the original manual operation and mechanical linkage are replaced by electronic buttons and motor actions, so the system is called electronic control mechanical parking brake system.

Extended data:

The electronic parking brake system has the following advantages:

1. The parking brake handle is cancelled in the carriage, which provides more space for the design of the interior shape of the whole vehicle.

2. The parking brake uses the key instead of the driver to pull the parking brake handle hard, which is simple and labor-saving, and reduces the operation intensity of the driver, especially the female driver.

3. With the development of automobile electronic parking control technology, the system can not only realize basic functions such as static parking, static release (off) and automatic release (off), but also add auxiliary functions such as automatic parking and dynamic parking.
