Abstract
A system a vehicle having a wheel-driving motor is disclosed. The system includes wheel speed sensors for detecting speed of respective vehicle wheels, and a controller for controlling coast regenerative torque of the vehicle. The controller lowers coast regenerative torque based on wheel speed acquired detected using the wheel speed sensors. The controller is lowers coast regenerative torque based on speed difference among the wheels and based on change of wheel slip ratio.
