Claims

[Scope of Claim for Utility Model Registration] In a hydraulic brake system for a vehicle that supplies brake fluid from a hydraulic pressure source to the braking device of each wheel in conjunction with a brake pedal, the brake operation detection means detects the depression operation of the brake pedal. a vehicle speed detection means for detecting the speed of the vehicle; a hydraulic pressure control means for supplying brake fluid to the braking device of each wheel from a hydraulic pressure source provided separately from the hydraulic pressure source; the brake operation detection means; Upon receiving a signal from the vehicle speed detection means, when the vehicle is stopped and the brake pedal is depressed, brake fluid is supplied to the braking device, and when the vehicle is stopped and the brake pedal is not depressed, the brake fluid is supplied to the braking device. 1. A hydraulic brake system for a vehicle, comprising: a controller for canceling the supply of brake fluid to the brake system.
