Abstract:
1. A parking brake control device for executing a parking brake control by using a brake system including an electric parking brake and a service brake, the electric parking brake generating a parking pressing force for moving a first friction material toward a second friction material by rotating an electric motor in a first direction, the electric parking brake accordingly generating a brake force by using friction between the first friction material and the second friction material, the service brake operating based on operation to a brake pedal and generating a brake force by moving the first friction material to the second friction material, the parking brake control device comprising: a lock control section for executing a lock control, the lock control being for: a release control section for executing a release control for releasing the brake force generated by the lock control section, wherein the lock control section includes a target determination section for determining the target value so that the target value becomes smaller in the case that the service brake is operating than in the case that the service brake is not operating.
