Claims

[Claims for Utility Model Registration] A master cylinder that applies hydraulic pressure to the wheel cylinders of each wheel via the brake pipe, and a proportioning valve that is installed in the middle of the rear wheel brake pipe to prevent the rear wheels from locking up. In a hydraulic brake system for a vehicle, a hydraulic pressure detection means for sensing changes in brake fluid pressure during braking is installed in the middle of the brake pipe on the front wheel side, and a hydraulic pressure detection means is installed at an arbitrary position on the vehicle body. A control circuit means is provided for generating an output signal having a phase that cancels the fluid pressure fluctuation of the brake fluid based on the detection signal of the fluid pressure detection means, and a control circuit means for generating an output signal having a phase that cancels the fluid pressure fluctuation of the brake fluid based on the detection signal of the fluid pressure detection means, and based on the output signal of the control circuit means, A hydraulic brake device for a vehicle characterized by being equipped with an actuator that excites hydraulic pressure.
