Abstract
PURPOSE:To save on the consumption of an electric current at what impresses a hold electric current on a motor which is to control the depressurization starting pressure of a brake liquid pressure control valve device, by changing the hold electric current according to the load of a spring which is operated on the basis of a command given to the motor. CONSTITUTION:A valve device 7 which is interveniently provided at a space between pipe passages 6, 8 which lead to the wheel cylinders of rear wheels 9a, 9b liquid pressure generated at a tandem master cylinder 1, is controlled by means of a pulse motor 10 provided in one body with this. The pulse motor 10 is controlled by means of a control pulse supplied by a controller 11 according to the carrying capacity of a vehicle and a hold electric current, by which a movable spring receiver 49 is displaced, and the spring load of a load spring 50 is made variable. Also, the hold electric current is impressed on the motor 10 for retaining a position, and in this instance, a spring load is operated on the basis of a command given to the motor 10, and a control is made so that the hold electric current may be changed according to its operation result.
