The present disclosure provides "brake assist during vehicle single pedal driving". The controller operates the friction brake to stop the vehicle in response to release of the accelerator pedal and a speed of the vehicle being less than a threshold during an absence of brake pedal engagement in the presence of an indication that available powertrain torque has decreased for at least a predetermined period of time. In the absence of the indication that available powertrain torque has decreased and brake pedal engagement, in response to release of an accelerator pedal and the speed being less than the threshold, the controller operates an electric machine instead of the friction brake to stop the vehicle.

    本公开提供了“车辆单踏板驾驶期间的制动辅助”。在不存在制动踏板接合期间,在至少预定时间段内存在有对可用动力传动系统扭矩已经减小的指示的情况下,响应于加速踏板的释放以及车辆的速度小于阈值,控制器操作摩擦制动器以使所述车辆停止。在不存在对可用动力传动系统扭矩已经减小的所述指示和制动踏板接合的情况下,响应于加速踏板的释放和所述速度小于所述阈值,所述控制器操作电机而不是所述摩擦制动器以使所述车辆停止。
