The invention provides a gear switching control system, method and device with redundant design and a storage medium, the system comprises a vehicle control unit, switching circuits and a caliper motor, the switching circuits comprise a first switching circuit and a second switching circuit, the control ends of the first switching circuit and the second switching circuit are connected with the vehicle control unit, and the caliper motor is connected with the vehicle control unit. The input end is suitable for being connected with external current, and the output end is connected with a caliper motor; the vehicle control unit is used for controlling the first switching circuit to be closed to supply external current to the caliper motor when the vehicle state meets the parking condition under the abnormal condition of the electronic stability system of the vehicle, and the caliper motor is controlled by a hard wire to execute the clamping action. And meanwhile, the control circuit is also used for controlling the second switching circuit to be closed to supply external current to the caliper motor and controlling the caliper motor to execute release action by a hard wire after the vehicle state meets a driving-off condition under the abnormal condition of the automobile electronic stability system. According to the invention, gear switching control can be realized when a communication loss fault occurs in the key frame of the automotive electronic stability system.

    本发明提供一种冗余设计的挡位切换控制系统、方法、设备及存储介质,系统包括整车控制器、开关电路和卡钳电机,开关电路包括第一开关电路和第二开关电路,第一开关电路和第二开关电路的控制端与整车控制器连接,输入端适于与外接电流连接,输出端与卡钳电机连接;整车控制器用于汽车电子稳定系统异常情况下,在车辆状态符合驻车条件后,控制第一开关电路闭合将外接电流给到卡钳电机,硬线控制卡钳电机执行夹紧动作;同时还用于汽车电子稳定系统异常情况下,在车辆状态符合驶离条件后,控制第二开关电路闭合将外接电流给到卡钳电机,硬线控制卡钳电机执行释放动作。本申请能实现汽车电子稳定系统关键帧出现通讯丢失故障时的挡位切换控制。
