PROBLEM TO BE SOLVED: To effectively prevent fixing of a brake pad and a disc rotor without especially modifying the existing structure of a brake and without increasing a cost and a weight.SOLUTION: Assuming that a "P" range is selected, a use history at a pre-set high temperature of brake pads 9RL and 9RR is available, and a road gradient &thetas;s does not exceed a pre-set threshold &thetas;c (for example, 5%), a parking brake control unit 31 repeats retaining one braking device 6RR (6RL) being of braking devices 6RL and 6RR of left and right rear wheels in an on state, bringing the other braking device 6RL (6RR) to an off state and thereafter to the on state, thereafter retaining the other braking device 6RL (6RR) in the on state, and bringing the one braking device 6RR (6RL) to the off state and thereafter to the one state, from the time when an electric parking brake system 30 is operated until a preset time Ta elapses. |
