ABSTRACT:
An electronic parking brake device for a vehicle including a slope sensor adapted to sense the slope of a road on which the vehicle is parked, and a parking brake control unit adapted to automatically carry out a control for a brake unit in response to the sensing operation of the slope sensor. The electronic parking brake device also includes a movement sensor adapted to sense a movement of the parked vehicle to achieve a secondary parking brake control. By this arrangement, the electronic parking brake device can prevent its brake control unit from malfunctioning due to electronic noise. Accordingly, it provides a safety and convenience to the driver. In particular, the electronic parking brake device of the present invention operates automatically to firmly prevent the vehicle from freely moving on a road with a slope. Accordingly, it is possible not only to provide an improvement in the security of passengers, but also to surely prevent the vehicle from being damaged.
