ABSTRACT:
The invention provides a process for performing calibration of the wheel speeds of a motor vehicle by periodically calculating and applying correction factors. The instantaneous speed of each wheel is measured periodically, and a vehicle turning rate is determined based on the time derivative of the differential between left and right wheel speeds. Actuation of the vehicle brakes is also detected. According to the invention, a new correction factor is determined only after the following criteria have been satisfied concurrently for a predetermined time period: vehicle speed is above a specified minimum, acceleration is within a specified range, vehicle turning is below a specified limit and the brakes are not actuated. In a second embodiment, vehicle driving torque is used as a criteria in place of acceleration.
