登録請求の範囲第１項記載の制動液圧制御装置。[Scope of Claim for Utility Model Registration] (1) The depression force of the brake pedal is supplied as hydraulic pressure to the hydraulic pressure control valve section through the master cylinder,
Braking in which hydraulic pressure from a hydraulic source is controlled by changing the port opening of a valve body of the hydraulic pressure control valve section that is moved by the hydraulic pressure, and the controlled hydraulic pressure is applied as a braking output to each wheel cylinder of the front and rear wheels. The hydraulic pressure control device includes a power piston that has a plurality of pressure receiving parts and presses and moves the valve body when hydraulic pressure from the master cylinder acts on these parts, and a power piston that acts on each of the pressure receiving parts. a switching means that switches to change the hydraulic pressure from the master cylinder; a load detection means that is installed between the sprung portion and the unsprung portion of the vehicle body to detect the weight of the vehicle; and a load detection device that is installed on the brake pedal and is actuated by pressing the brake pedal. Calculates the amount of operation of the switching means based on the detection signal from the pedal operation detection means and the load detection means, and when the detection signal from the pedal operation detection means is input, the amount of operation of the switching means is calculated based on the calculation of the amount of operation. A brake hydraulic pressure control device comprising: a control unit that outputs a switching control signal to the switching means. (2) The switching means is configured to include a plurality of pairs of normally-closed and normally-open solenoid valves that operate synchronously, and the pairs of valves are sequentially operated in stages corresponding to the amount of operation. A brake hydraulic pressure control device according to claim 1, characterized in that:
