[0002] Automobile braking system is the core safety system. Traditional automobiles use vacuum-assisted hydraulic braking system, and the engine provides a vacuum negative pressure source; electric vehicles do not have a vacuum source. Currently, the commonly used electric vacuum assist system method uses an electric vacuum pump to provide negative pressure. The method has the disadvantages that the vacuum pump needs to work all the time, the continuous braking effect is poor, the system noise is large, and the reliability is poor. Braking system, the brake-by-wire system can realize the decoupling of the motor brake and the mechanical brake of the driver's pedal, but once the wire-control system fails, it will be difficult to achieve braking, and the reliability is not high. Electric brake coupling, can not play the best effect of the system
