Abstract:
The method for controlling a safety system (102-108) of a vehicle (10) determines a reference velocity from a first front wheel sensor (20A) and a second front wheel speed signal from a second front wheel sensor (20B). An axle speed sensor (20C) may be used to determine an axle speed signal. A first rear speed signal and a second rear speed signal are determined from the reference velocity, a slip effect and a yaw signal. The yaw signal may be determined from a yaw rate sensor (28). Safety system (102-108) may be controlled in response to the first rear wheel speed signal and the second rear wheel speed signal.
