The invention discloses a brake device with an electronic brake booster. The brake device is characterized by comprising a treading unit, a boosting unit and a wheel unit, the boosting unit comprises a main cylinder, a liquid storage tank for providing brake liquid for the main cylinder, a main cylinder piston arranged in the main cylinder and in transmission connection with a transmission mechanism, a boosting motor for driving the transmission mechanism, and an ECU; and the wheel unit comprises a first set of wheels with two wheels and a second set of wheels with two wheels, brakes of the first set of wheels are controlled by a first ECU, the first ECU is an ECU in the power assisting unit, brakes of the second set of wheels are controlled by a second ECU, and the second ECU is an ECU in the power assisting unit or an ECU in the electromechanical brake. The two sets of wheels are controlled through the at least two ECUs, when one ECU fails and the corresponding wheel cannot achieve braking, the other ECU can take over and control the other wheel to achieve braking, and vehicle safety is guaranteed.
本发明公开的是带电子制动助力器的制动装置,其特征在于,包括踩踏单元、助力单元和车轮单元,所述助力单元包括主缸、为主缸提供制动液的储液罐、设于主缸内与传动机构传动连接的主缸活塞、驱动传动机构的助力电机以及ECU,所述车轮单元包括具有两个车轮的第一组车轮和具有两个车轮的第二组车轮,第一组车轮的制动器由第一ECU控制,所述第一ECU为助力单元中的ECU,第二组车轮的制动器由第二ECU控制,所述第二ECU为助力单元中的ECU或电子机械制动器中的ECU。两组车轮通过至少两个ECU进行控制,当其中一个ECU失效,对应的车轮无法实现制动时,可由另外的ECU接管,控制另外车轮实现制动,保证车辆安全。
