特徴とする車両の駐車ブレーキ制御装置。 A brake drive circuit that operates or deactivates the parking brake by opening and closing an operating pressure passage connecting the operating pressure source and the parking brake, and a first driver's seat operation command means that opens and closes the operating loop of the brake drive circuit when operated. and a second driver's seat operation command means that opens and closes the operating loop of the brake drive circuit by turning on the second driver's seat key switch, and detects that the pressure of the operating pressure source has fallen below a set value. A low pressure switch, a first alarm circuit that forms an alarm buzzer operation loop by the on operation of the low pressure switch when the first driver's seat key switch is on, and a first driver's seat key switch when the first driver's seat key switch is off. a second alarm circuit that forms an activation loop for an alarm buzzer on the condition of an activation command of the activation command means; Forcibly interrupting the operation loop of a third alarm circuit forming an operation loop of an alarm buzzer and a brake drive circuit according to an operation command of the first operation command means for the driver's seat when the first key switch for the driver's seat is turned off. 1. A parking brake control device for a vehicle, comprising a blocking means.
