Abstract
An apparatus for determining wheel slippage which may be utilized for traction control of an automotive vehicle is provided. This apparatus determines a compliance wheel speed difference between right and left compliance wheels. When the compliance wheel speed difference is smaller than a preselected threshold value, a compliance wheel reference speed is determined by averaging right and left compliance wheel speeds, when it is greater than the preselected threshold value, the compliance wheel reference speed is determined based on a greater one of the right and left compliance wheel speeds. The apparatus determines a degree of the wheel slippage based on a difference between the compliance wheel reference wheel and a driven wheel speed.
