System and method for controlling torque of electric vehicle

A method for controlling a torque of an electric vehicle, comprising:

• applying, by the controller, an offset torque, which is a parameter predetermined by a driver, to a basic creep torque line to set an offset torque line varied from the basic creep torque line in a negative (−) torque direction, when the predetermined offset torque is zero;
• calculating, by the controller, a driver creep torque depending on a speed of the electric vehicle based on the offset torque line when the predetermined offset torque is greater than zero;
• calculating, by the controller, a driver demand torque based on the speed of the electric vehicle and a position of an accelerator pedal;
• and
• summing, by the controller, the driver demand torque and the driver creep torque to determine a final torque of a motor.

A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

• program instructions that apply an offset torque, which is a parameter predetermined by a driver, to a basic creep torque line to set an offset torque line varied from the basic creep torque line in a negative (−) torque direction, when the predetermined offset torque is zero;
• program instructions that calculate a driver creep torque depending on a speed of an electric vehicle based on the offset torque line when the predetermined offset torque is greater than zero;
• program instructions that calculate a driver demand torque based on the speed of the electric vehicle and a position of an accelerator pedal;
• and
• program instructions that sum the driver demand torque and the driver creep torque to determine a final torque of a motor.
