とを特徴とする車両用ブレーキ制御装置。 Forward/forward switching means for switching the running direction of the vehicle;
A negative parking brake device releases braking force by supplying pressure from a pressure source and applies braking force to the vehicle by discharging the pressure, and a negative parking brake device releases braking force from the pressure source by external operation. In a vehicle brake control device comprising a parking brake valve that supplies and discharges pressure to the parking brake device, the parking brake valve is an electromagnetic switching valve that is switched between a pressure supply position and a pressure discharge position by an external operating means. Accordingly, the forward/reverse switching means is provided with neutral position detecting means for detecting whether or not the forward/reverse switching means has been switched to a neutral position to stop the vehicle, and the detecting means detects the neutral position. A brake control device for a vehicle, characterized in that the electromagnetic switching valve is sometimes switched to a discharging position regardless of the operating position of the external operating means.
