Abstract

A method for controlling vehicle creep includes controlling motor speed to produce the desired creep speed, if desired creep speed exceeds vehicle speed; controlling motor torque to produce the desired wheel torque, if desired wheel torque exceeds actual wheel torque; and controlling motor torque to decelerate the vehicle to creep speed, if vehicle speed is decreasing and exceeds the desired speed.
