Abstract:
An electric vehicle comprising:a shift position sensing device for sensing a shift position of a transmission disposed between a motor and driving wheels; a vehicle speed sensing device for sensing a vehicle speed; an accelerator sensing device for sensing an accelerator control input; a creep torque setting device for setting creep torque in accordance with said vehicle speed sensed by a vehicle speed sensing device when said shift position sensing device senses a running shift position; an acceleration torque setting device for setting acceleration torque in accordance with the accelerator control input; a driving torque calculating device for calculating driving torque by adding the creep torque, which is set by said creep torque setting device, to the acceleration torque, which is set by said acceleration torque setting device; and a drive control device for running a motor in accordance with the driving torque calculated by said driving torque calculating device; wherein the creep torque setting device maintains the creep torque at a predetermined creep torque when the vehicle speed sensed by the vehicle speed sensing device is within a range between zero and a first predetermined vehicle speed; and wherein the creep torque setting device reduces the creep torque from the predetermined creep torque to zero as the vehicle speed sensed by the vehicle speed sensing device increases from the first predetermined vehicle speed to a second predetermined vehicle speed.
