The invention provides a single pedal driving method for controlling vehicle speed to stop. A controller operates an electric machine to provide a braking torque to a time profile according to a predetermined speed in response to an accelerator pedal release and a speed of a vehicle being less than a threshold, the predetermined speed-to-time profile defines a predetermined duration during which the speed becomes zero and a target speed at each time during the predetermined duration such that, for a given one of the times, the motor increases the braking torque in response to the speed being greater than the target speed, and reducing the braking torque in response to the speed being less than the target speed. 本公开提供了"将车辆速度控制到停止的单踏板驾驶方法"。一种控制器响应于加速踏板释放并且车辆的速度小于阈值而操作电机，以根据预定速度对时间配置文件来提供制动扭矩，所述预定速度对时间配置文件限定所述速度变为零的预定持续时间和在所述预定持续时间期间的每个时刻的目标速度，使得对于所述时刻中的给定时刻，所述电机响应于所述速度大于所述目标速度而增加所述制动扭矩，并且响应于所述速度小于所述目标速度而减小所述制动扭矩。
