Abstract
A method for inhibiting automatic actuation of an electric parking brake (EPB) system of a motor vehicle is disclosed. The vehicle has an ignition switch for receiving an ignition key so as to mobilize or immobilize the vehicle. The EPB system includes an EPB mechanism for applying an actuating force to a park brake of the vehicle, an EPB control module for automatically applying the force when at least the ignition key is detected as removed from the ignition switch and an EPB control switch. The EPB control switch can be moved towards two instable positions from a neutral position respectively a brake release position and a brake apply position so as to apply or release the park brake. To inhibit the automatic actuation of the park brake, the driver has to complete within a specific time period the cycle of turning the ignition from off to on to off, pressing and maintaining the EPB control switch into the brake release position, removing the ignition key and releasing the EPB control switch after at least a predetermined time period. Such cycle of actions will be interpreted by the EPB control module as a wish to not apply the park brake.
