The invention provides a motor controller and a power assembly, relates to the field of new energy automobiles, and can be applied to a double-drive electric vehicle or a hybrid vehicle. The motor controller is used for the vehicle and used for receiving power supplied by a power battery and outputting driving current to a driving motor so that the driving motor can output torque. In the process that the motor controller outputs the driving current, the motor controller is used for responding to the fault of the motor controller, outputting a first fault signal and stopping outputting the driving current to the driving motor, and the first fault signal is used for indicating another motor controller of the vehicle to control another driving motor of the vehicle to increase torque output. According to the scheme, when one motor controller breaks down, the normal motor controller controls the driving motor to output the torque, it can be guaranteed that the power of the whole vehicle is not lost, and the safety of the vehicle is improved.
本申请提供一种电机控制器和动力总成,涉及新能源汽车领域,可应用于双驱电动车或混动车辆。电机控制器用于车辆,电机控制器用于接收动力电池供电并向驱动电机输出驱动电流以使驱动电机输出扭矩;在电机控制器输出驱动电流过程中,电机控制器用于响应于电机控制器故障,输出第一故障信号并停止向驱动电机输出驱动电流,第一故障信号用于指示车辆的另一个电机控制器控制车辆的另一个驱动电机增大扭矩输出。根据本申请的方案,当一个电机控制器发生故障,由正常的电机控制器控制驱动电机输出扭矩,可以保障整车动力不丢失,提高车辆的安全性。
