The invention provides a vehicle brake backup method for EMB system failure, which is based on a central controller and four wheel end EMB controllers and brakes connected with the central controller, and comprises the following steps: S1, collecting signals of a brake pedal, a power system and wheel speed; s2, setting control logic of a wheel end EMB controller relative to a brake pedal, a power system and a wheel speed signal; and S3, the wheel end EMB controller conducts brake clamping and brake releasing on the wheels according to the set control logic. Under the condition that the central controller of the EMB system fails, the driving and braking functions of the vehicle can still be achieved according to the braking intention of a driver, and the safety is improved. Reasonable control logic is set to control the braking speed and the braking torque of the wheel end EMB controller, the wheel anti-lock function is considered, the braking intention of a driver is matched, and the safety principle of emergency braking can also be followed.

    本发明提供了一种针对EMB系统失效的车辆制动备份方法,基于中央控制器以及与其连接的四个轮端EMB控制器和制动器,包括以下步骤:S1:采集制动踏板、动力系统、轮速的信号;S2:设置轮端EMB控制器相对于制动踏板、动力系统及轮速信号的控制逻辑;S3:轮端EMB控制器根据设置的控制逻辑来对车轮实现制动夹紧和解除制动。本发明在EMB系统发生中央控制器失效的情况下,仍能够按照驾驶者的制动意图,实现车辆的行驶、制动功能,提高安全性。本发明设置合理的控制逻辑控制轮端EMB控制器的制动速率和制动力矩,并且考虑车轮防抱死功能,不仅匹配了驾驶员的制动意图,也能遵循紧急制动的安全原则。
