Abstract
A vehicle includes a controller programmed to generate a command to an electric machine to reduce a torque output rate after an accelerator pedal is tipped out based upon a vehicle speed value and a wheel acceleration torque value. The torque output rate is initially reduced at a first rate, and is then reduced at a second rate slower than the first rate when the wheel acceleration torque value is greater than 0 Nm.
