Abstract
A rotational speed Vof a left front wheel T, a rotational speed Vof a right front wheel T, a rotational speed Vof a left rear wheel T, and a rotational speed Vof a right rear wheel Tare detected by rotational speed sensors S-S, respectively. A front-wheel yaw rate γF arising due to a rotational speed difference between the front wheels T, Tand a rear-wheel yaw rate γR arising due to a rotational speed difference between the rear wheels T, Tare monitored. When a significant disparity between the both rotational speed differences is observed, it is determined that tire inflation pressure of any of the wheels T-Thas decreased. Upon detection, correction is made to an apparent yaw rate that would be observed in the properly inflated wheel as a result of steering for correction by a driver, thereby improving detection accuracy of underinflation of the tires.
