The invention discloses an all-terrain vehicle emergency mode control method and device, and the method comprises the following steps: an accelerator pedal inputs a signal, the signal is recognized by an engine ECM, and after the signal is recognized, the signal is fed back to a vehicle control unit through a CAN bus; when an emergency situation occurs, the vehicle control unit receives an emergency signal and sends the emergency signal to an instrument panel through a CAN bus, at the moment, a DO port, corresponding to the main pump electromagnetic valve, of the vehicle control unit forbids output, and the vehicle cannot run; and after stopping, the vehicle control unit enters an emergency mode when recognizing a forward signal of a gear switch for five times within 10s, in the emergency mode, the vehicle control unit limits the output of a DO port of a main pump solenoid valve, the maximum output current value is limited to be 25% of the maximum current in a normal driving state, and the vehicle can slowly drive to a safe area for maintenance.

    本发明公开了一种全地形车应急模式控制方法及装置,方法包括以下步骤:油门踏板输入信号并由发动机ECM识别,识别信号后通过CAN总线将该信号反馈至整车控制器→整车控制器判断踏板输入信号,输出相对应电流值至主泵电磁阀使整车行驶→出现紧急情况,整车控制器接收到紧急信号并由CAN总线将紧急信号发送至仪表盘,此时整车控制器对应主泵电磁阀DO端口禁止输出,车辆无法行驶→车辆进入应急模式,停下后整车控制器在10s内识别到档位开关前进信号5次时,进入应急模式→应急模式下,整车控制器对应主泵电磁阀DO端口输出进行限制,输出最大电流值限定为正常行驶状态时最大电流的25%,车辆能缓慢行驶至安全区域进行检修。
