Abstract
A system and method for determining backlash in a driving system of a vehicle are provided. The system includes a motor speed sensor that detects a motor speed and a wheel speed sensor that detects a wheel speed. A speed difference determination unit receives the detected motor and wheel speeds and determines a rotational speed difference of the driving system. A torsion speed determination unit receives the determined rotational speed difference and determines a reference torsion speed for backlash determination of the driving system. A backlash determination unit receives the determined rotational speed difference and the determined reference torsion speed, determines a backlash speed corresponding to a difference between the rotational speed difference and the reference torsion speed, and determines whether backlash in the driving system occurs using the determined backlash speed.
