Abstract
In a vehicle behavior control system, a failure of a wheel speed sensor is detected by a wheel speed sensor failure detecting device based on the mutual comparison of wheel speeds detected by wheel speed sensors, respectively. When the failure of the wheel speed sensor is detected, a preselected fail-safe operation is carried out by a fail-safe device. A fail-safe operation prohibiting signal is output only for a predetermined time from the establishment of a state in which the operation of a parking brake is detected by a parking brake operation detecting device and a during-traveling signal is output from a during-traveling signal generated device. When the fail-safe operation prohibiting signal is output, the fail-safe operation by the fail-safe device is prohibited by a fail-safe operation prohibiting device.
