ABSTRACT:
An apparatus for detecting wheel speed in a motor vehicle. The apparatus includes first, second, and third sensors for outputting pulse signals in response to rotations of rotary shafts of front left and right wheels and a drive shaft, respectively, and a rotational angular velocity calculating member for calculating first, second, and third rotational angular velocities of the first and second rotary shafts and the drive shaft from the pulse signals, respectively. The apparatus also provides a front wheel speed calculating member for calculating first and second wheel speeds of the front left and right wheels from the first and second rotational angular velocities, an average front wheel speed calculating member for calculating an average front wheel speed from the first and second wheel speeds, a factor correcting member for correcting a conversion factor including a change gear ratio of a transmission mechanism and a wheel radius, and an average rear wheel speed calculating member for calculating an average rear wheel speed from the third rotational angular velocity and the conversion factor.
