The invention relates to a redundant motor driving circuit and a vehicle, the circuit comprises a motor driving module, a redundant control module and an energy feedback module, and the motor driving module is used for driving a motor to operate according to a driving signal sent by the redundant control module; when a first driving signal generation unit of the redundancy control module is in a non-fault state, the first driving signal generation unit generates a driving signal, when the first driving signal generation unit is in a fault state, a second driving signal generation unit generates a driving signal, and a first control unit is used for sending the driving signal to a motor driving module; and the energy feedback module is used for discharging the running energy of the motor when both the first driving signal generation unit and the second driving signal generation unit fail or the redundant motor driving circuit enters a power-off state. Therefore, the problem that when one control chip goes wrong, a motor driving loop is abnormal due to the fact that no safety mechanism exists is solved, and when the controller is abnormal, energy of the motor can be rapidly transmitted out.

    本申请涉及一种冗余电机驱动电路及车辆,该电路包括:电机驱动模块、冗余控制模块和馈能模块,电机驱动模块用于根据冗余控制模块发送的驱动信号驱动电机运转;冗余控制模块的第一驱动信号生成单元在未故障状态时,由第一驱动信号生成单元生成驱动信号,第一驱动信号生成单元在故障状态时,由第二驱动信号生成单元生成驱动信号,利用第一控制单元发送驱动信号至电机驱动模块;馈能模块,用于在第一驱动信号生成单元和第二驱动信号生成单元均故障时,或者冗余电机驱动电路进入下电状态时,泄放电机运转的能量。由此,解决了在一个控制芯片出现问题时,由于没有安全机制而导致电机驱动回路异常等问题,在控制器异常时,可以将电机的能量快速传出。
