Claim 3:
4. A system for controlling a rate of deceleration of a vehicle comprising:
a vehicle speed indicator providing vehicle speed data;
a wheel torque indicator providing a wheel torque value;
a controller programmed with a data table including the vehicle speed data, and wheel torque data, wherein when an accelerator pedal is in a tip-out position the controller generates a first deceleration rate value based upon the wheel torque data, the vehicle speed data, and the data table;
commanding an 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.
