ABSTRACT:
A device for calculating a correction factor for correcting an output of a rotational velocity detecting device for detecting the rotational velocities of right and left tires mounted on a vehicle. Discrimination between a state where the vehicle is traveling linearly and a state where the vehicle is traveling on a curved path is made on the basis of the output of the rotational velocity detecting device. Only when it is judged that the vehicle is traveling linearly, an initial correction factor for eliminating the effect of a difference in effective rolling radius between the tires, depending on an initial difference on the rotational velocities of the tires, is calculated.
