Claim 0:
1. A method of controlling deceleration of an electric vehicle comprising:
providing a controller that is programmed with a data table to command an electric motor;
providing the controller with position data indicating that an accelerator pedal is in a tip-out position;
providing the controller with wheel torque data;
providing the controller with vehicle speed data when the accelerator pedal is in the tip-out position, wherein the controller generates a first deceleration rate value based upon the wheel torque data, the vehicle speed data, and the data table;
commanding the electric motor based on the first deceleration rate value to set a first wheel torque output rate for a first time period;
providing the controller with the wheel torque data, and the vehicle speed data after the first time period with the accelerator pedal in the tip-out position, wherein the controller generates a second deceleration rate value based upon the wheel torque data, the vehicle speed data, and the data table; and
commanding the electric motor based on the second deceleration rate value to set a second wheel torque output rate for a second time period, wherein the second wheel torque output rate is less than the first wheel torque output rate.
