The invention provides a power supply circuit, a motor controller and a vehicle, and the power supply circuit comprises a high-voltage auxiliary power supply, a low-voltage power supply, a logic circuit, and a trailer protection circuit. The trailer protection circuit is connected with the logic circuit, when the output end of the trailer protection circuit has voltage, the logic circuit outputs an ASC enable signal, and when the output end of the trailer protection circuit has no voltage, the logic circuit does not output the ASC enable signal; the trailer protection circuit comprises a first enabling unit, a second enabling unit and a switch unit, and the first enabling unit is used for outputting a conduction enabling signal to the switch unit when a low-voltage power supply is powered on; and the output end of the second enabling unit is connected with the input end of the switch unit, and the second enabling unit is used for inputting a conduction enabling signal to the switch unit based on the high-voltage auxiliary power supply. On the premise that the vehicle can normally trigger the ASC state in the normal driving process, the vehicle can be prevented from entering the ASC state in the vehicle dragging process.

    本申请提供一种电源电路、电机控制器和车辆,其中,电源电路包括:高压辅助电源、低压供电电源、逻辑电路和拖车保护电路;拖车保护电路与逻辑电路连接,拖车保护电路的输出端有电压时,逻辑电路输出ASC使能信号,拖车保护电路的输出端无电压时,逻辑电路不输出ASC使能信号;拖车保护电路包括第一使能单元、第二使能单元、开关单元,第一使能单元用于在低压供电电源上电时,向开关单元输出导通使能信号;第二使能单元的输出端与开关单元的输入端连接,第二使能单元用于基于高压辅助电源向开关单元输入导通使能信号。本申请能够在确保车辆正常行驶过程能够正常触发ASC状态这一前提下,防止在拖车过程中,车辆进入ASC状态。
