Starting method and device of driving motor system, vehicle and storage medium

The invention discloses a starting method and device of a driving motor system, a vehicle and a storage medium, and the method comprises the steps: reading an IGBT temperature signal of the driving motor system, and obtaining an actual IGBT temperature; when it is detected that the actual IGBT temperature is smaller than the preset low temperature, it is judged that the IGBT temperature signal is invalid, and a motor temperature signal of the driving motor system is obtained; and the current IGBT temperature of the driving motor system is determined according to the motor temperature signal replacing the IGBT temperature signal, and the driving motor system is started based on the current IGBT temperature, so that the vehicle enters the limping mode. Therefore, the problem that the driving motor system misreports faults under the low-temperature working condition is solved, and it is guaranteed that the driving motor system can stably and reliably work under the low-temperature working condition. 本申请公开了一种驱动电机
