The invention provides a brake redundancy control motor controller and an electronic mechanical brake system.The motor controller is connected with a driving motor of a vehicle and controls the driving motor to output torque, and the motor controller is connected with a brake pedal sensor and receives a brake pedal signal from the brake pedal sensor; the brake pedal signal is used for indicating the motion state of a brake pedal, the motor controller is connected with the central controller and the four wheel end brake devices, the central controller is used for controlling the four wheel end brake devices to output braking force to a brake disc of the vehicle, and the motor controller responds to the failure of the central controller and controls the brake disc to brake. And controlling the four wheel end braking devices to output braking force according to the indication of the brake pedal signal. Thus, even if the central controller responsible for controlling the wheel end braking devices in the electronic mechanical braking system fails, the motor controller can control the four wheel end braking devices to output the braking force, the situation that the wheel end braking devices are out of control is avoided, and therefore the braking reliability and safety of the vehicle are improved.
本申请提供一种制动冗余控制的电机控制器及电子机械制动系统,电机控制器连接车辆的驱动电机并控制驱动电机输出扭矩,电机控制器连接制动踏板传感器并接收来自制动踏板传感器的制动踏板信号,制动踏板信号用于指示制动踏板的运动状态,电机控制器连接中央控制器以及四个轮端制动装置,中央控制器用于控制四个轮端制动装置向车辆的刹车盘输出制动力,电机控制器响应于中央控制器失效,根据制动踏板信号的指示控制四个轮端制动装置输出制动力。如此,即使电子机械制动系统中负责控制轮端制动装置的中央控制器失效,电机控制器也可以控制四个轮端制动装置输出制动力,避免轮端制动装置失去控制,从而提高车辆的制动可靠性与安全性。
