Patent ID: 8515703

Claim:
A method for calibrating a wheel speed detection system in a vehicle, the system comprising at least one wheel speed sensor which supplies a wheel speed sensor output signal, and at least one electronic control unit (ECU), the method comprising: determining, by the ECU, a sensed distance traveled by the vehicle based on the at least one wheel speed sensor output signal, setting, by the ECU, the traveled distance as a reference distance if the following two conditions are satisfied: a curvature of the traveled distance does not exceed a predefined curvature limit, the curvature calculated by the ECU based on at least one of satellite navigation information and steering angle information, and a negative acceleration or a positive acceleration of the vehicle over the traveled distance does not exceed a predefined acceleration limit; and calibrating, by the ECU, the wheel speed detection system based on a quotient computed between a navigation distance determined based on signals received by the vehicle, and the reference distance.
