一种解耦式制动踏板端信号失效后的控制方法及控制系统

The invention discloses a control method and a control system for a decoupled brake pedal end signal after failure, and relates to the technical field of new energy automobiles, wherein the control method comprises the steps of switching an electronic parking brake switch from a threshold mode to a brake intention recognition mode when the brake pedal end signal fails; the method comprises the steps of obtaining a braking intention signal, determining a target vehicle braking force according to the braking intention signal and current vehicle state information, and controlling a braking system execution unit to brake a vehicle according to the target vehicle braking force. The problems that when a decoupled brake pedal end signal is abnormal, a driver cannot regulate and control the braking force, the EPB electronic parking switch can only be used for braking when a vehicle moves at a low speed, and the driver cannot brake the whole vehicle through the brake pedal can be solved, and the safety braking and parking of the vehicle are ensured.
