[0002] Automobile brakes refer to the components that generate force (braking force) that hinders the movement or movement tendency of the vehicle, including the buffer device in the auxiliary braking system. At present, automobile brakes are generally controlled by hydraulic systems, that is, by using hydraulic pressure to press the pads Relying on discs for braking reliability, or using pneumatic systems for braking, electromechanical brakes (EMB) have a fairly simple structure and good braking, so EMB has been widely used, EMB directly converts motor power into linear However, the structure of the electromechanical brake is relatively complicated, there are many links in the intermediate connection process, the failure rate is relatively high, and the braking speed and braking effect are relatively poor, and the response time of the whole vehicle is long, which affects the safety of driving. safety

The invention discloses an electronic wedge brake system, which comprises a central controller, an electronic wedge braker which is arranged on each wheel and a motor driver which is electrically connected with central controller, wherein the electronic wedge braker of each wheel is electrically connected with the motor driver; and an electronic braking pedal and a parking emergent braking controller are connected to the central controller. According to the electronic wedge brake system, the conventional air brake system and anti-lock brake system (ABS) are integrated, so that a structure of the conventional brake system can be simplified greatly, is electronized and automated completely and is reasonable in design; due to the adoption of the connection of wiring harnesses, the wiring is convenient; the central controller is used as a processing center, so the intelligentized degree is high; and the motor driver is electrically connected with the central controller, so that the electronic wedge brakers can be controlled accurately in time.
