What are the three braking principles of automatic transmission cars?

The three braking principles of automatic transmission vehicles are:

First, the foot brake:

A wheel or disc is fixed on the high-speed shaft of the machine, and the corresponding brake shoe, belt or disc is installed on the base to make it produce braking torque under the action of external force.

Second, the handbrake:

Parking brake is controlled by the friction between brake disc and brake pad, but the control mode is changed from manipulator brake lever to electronic button.

Third, P braking:

The purpose of fixing the vehicle is achieved by mechanically locking the output shaft of the transmission, and its function is to brake after parking and prevent the vehicle from moving.

The specific operation steps of using these three braking methods are as follows:

1, step on the brake pedal to slow down the vehicle.

2. Park the vehicle on a safe road.

Put the gear lever of the car in P position, which is the parking position.

4. Pull up the electronic handbrake switch of the car.

5. Press the one-button start button of the car to turn off the car.
