Device for determining initial correction factor for correcting rotational velocity of tire
First Claim
1. A device for determining a correction factor for correcting an output of a rotational velocity detector, the detector for detecting the rotational angular velocities of four tires mounted on a vehicle, the device comprising:
- means for judging whether or not the vehicle is traveling linearly; and
means for calculating initial correction factors K1 and K2 when the linear travel judging means judges that the vehicle is traveling linearly, wherein the initial correction factor K1 is for eliminating an effect of a difference in effective rolling radius depending on an initial difference between right and left front tires on the rotational velocity of the tires and the initial correction factor K2 is for eliminating an effect of a difference in effective rolling radius depending on an initial difference between right and left rear tires on the rotational velocities of the tires on the basis of the output of the rotational velocity detector.

Abstract
A device for finding correction factors for correcting outputs of rotational velocity detectors used for detecting the rotational velocities of four tires mounted on a vehicle. The device judges whether or not the vehicle is traveling linearly. If the vehicle is traveling linearly, an initial correction factor K1 for eliminating the effect of a difference in effective rolling radius between the right and left front tires, and an initial correction factor K2 for eliminating the effect of a difference in effective rolling radius between the right and left rear tires, are calculated on the basis of the outputs of the rotational velocity detectors. When it is judged that the vehicle is coasting linearly, an initial correction factor K3 for eliminating the effect of a difference in effective rolling radius between the front tire and the rear tire is calculated.
