A method of controlling an electric machine of a vehicle includes monitoring torque command signals from a vehicle system to the electric machine, each torque command signal configured to cause the electric machine to output a command torque, and monitoring a speed of the vehicle and an output torque of the electric machine, the output torque responsive to a drive signal generated based on the torque command signals. The method further includes modulating the drive signal between a first torque value and a second torque value less than the first torque value based on the output torque and a vehicle speed indicative of a low motor efficiency condition, the first torque value being greater than the commanded torque and selected to increase efficiency of the motor.

    一种控制车辆的电机的方法包括监控从车辆系统到电机的扭矩指令信号,每个扭矩指令信号被配置成使电机输出指令扭矩,以及监控车辆的速度和电机的输出扭矩,输出扭矩响应于基于扭矩指令信号产生的驱动信号。该方法还包括,基于输出扭矩和指示低电机效率状况的车速,在第一扭矩值和小于第一扭矩值的第二扭矩值之间调制驱动信号,第一扭矩值大于指令扭矩并被选择以增加电机的效率。
