Abstract
A technique to indicate a different-diameter wheel such as a temporary tire and to accurately correct the wheel speed of the different-diameter wheel is determined. Wheel speeds of a pair of left and right driven wheels are detected by wheel speed sensors and wheel speeds of a pair of left and right follower wheels are detected by wheel speed sensors. Yaw rates are calculated from the wheel speeds of the left and right wheels, and yaw rates are calculated from the wheel speeds of the wheels located diagonally. Which wheel of the four wheels is a different-diameter wheel is determined based on the magnitudes of the four yaw rates and the wheel speed of the different-diameter wheel is corrected based on a ratio in wheel speed between the different-diameter wheel and the other wheels.
