Abstract: A process for determining the wheel radius ratios of a vehicle equipped with an anti-lock braking system uses the rotational speeds of the vehicle wheels to determine a vehicle drive slip value. This drive slip value and the driving force of the vehicle drive wheels are combined in a Kalman filter to compute the wheel radius ratio data. When traveling around curves, however, the drive slip value calculation can become inaccurate, thereby corrupting the computed wheel radius ratio data. To correct for this curve travel effect, the inventive process includes the yawing rate of the vehicle in its computations. As a result, the corrected wheel radius ratios can be more reliably used for detecting tire pressure problems.
