Zusammenfassung:The present disclosure provides "inefficient electric motor operation during charge limiting vehicle operation". A driveline includes an electric machine, an inverter, and a controller. For a given operating point of the electric machine, the controller may schedule a commutation method of a switch of the inverter during the presence of a negative wheel torque request according to a charge rate corresponding to the negative wheel torque request, a temperature of the electric machine and/or the inverter, and/or a battery state of charge. 本公开提供了"在充电限制车辆操作期间的低效电动马达操作"。一种传动系包括电机、逆变器和控制器。对于电机的给定操作点,控制器可以根据对应于负车轮扭矩请求的充电速率、电机和/或逆变器的温度和/或电池荷电状态,在存在负车轮扭矩请求期间调度逆变器的开关的换向方法。
