  • Publication number: 20140246897
    Abstract: A vehicle brake device includes a hydraulic pressure generating device, a valve device, a pump and an accumulation section forming an accumulation chamber connected to a fluid passage between the valve device and the hydraulic pressure generating device or to a master chamber. A dead band is set in which the change of force of the magnitude corresponding to the hydraulic pressure in the master chamber does not substantially act on a brake operating member. A characteristic representing the relation between the pressure and the brake fluid quantity in the accumulation chamber is set based on a characteristic representing the relation between the pressure and the brake fluid quantity in a wheel cylinder and the dead band so that, when brake fluid is flowing into and from the accumulation chamber, a force of the magnitude corresponding to the master chamber hydraulic pressure does not act on the brake operating member.

  • Patent number: 7669942
    Abstract: A brake system and a brake device for use with automobiles is provided in which braking energy stored in an auxiliary pressure source can be effectively used for braking, even if an electrical system fails. The vehicle brake system includes a proportional pressure control valve for generating braking liquid pressure by adjusting the braking energy stored in the auxiliary pressure source. A passage transmits the liquid pressure generated by a brake pedal stroke, a switching valve opens the passage in the powered condition and closes the passage in the off-powered condition, and an auxiliary control portion activates the proportional pressure control valve. Even in the off-powered condition, the high pressure accumulated in the auxiliary pressure source can be used to adjust the required braking liquid pressure at the proportional pressure control valve.
