摘要： A vehicle hydraulic brake apparatus includes a brake member, a master cylinder generating brake hydraulic pressure, and a master piston movable in response to operation of the brake member. A closed chamber is defined by the master piston and a power piston is disposed behind the master piston. A power chamber is defined by the power piston rearwardly of the power piston. An auxiliary hydraulic pressure source generates power hydraulic pressure and a pressure regulating device regulates the output power hydraulic pressure and feeds it to the power chamber. A reaction force member is disposed in a front end portion of the power piston and is exposed towards the closed chamber. A retaining device maintains the reaction force member exposed towards the closed chamber, with the rearward reaction force of the master piston being transmitted to a front end portion of the power piston while bypassing the reaction force member.

摘要： A hydraulic brake apparatus is provided for increasing a braking force with a brake feeling similar to that during a normal brake operation, even if a brake pedal is operated during an automatic brake operation. A valve device having a spool is placed in a power piston and is transferred between first and second positions depending on the operation of the brake pedal. At the first position, a power chamber is at atmospheric pressure level, while at the second position a fluid communication is established between the power chamber and an auxiliary hydraulic pressure source. The spool is driven independent of the operation of the brake pedal. When a hydraulic pressure is applied to the spool, the valve device is switched to the second position, urging the power piston to advance, without transmitting the resultant force to the brake operation member. The driving device, when applied with no hydraulic pressure, retains the valve device at the first position.

摘要： A hydraulic brake apparatus for a vehicle includes a supplementary hydraulic pressure source outputting a pressurized output hydraulic pressure and an electronic control apparatus that controls a hydraulic pump in the supplementary hydraulic pressure source. The electronic control apparatus judges whether the hydraulic pump satisfies a predetermined operating condition based on the output hydraulic pressure of the supplementary hydraulic pressure source or not. The electronic control apparatus compares the output hydraulic pressure with a minimum standard hydraulic pressure, detects a drop in the output hydraulic pressure when the output hydraulic pressure is less than a standard hydraulic pressure and determines that the hydraulic pump does not satisfy the predetermined operating condition.

摘要： A vehicle hydraulic brake control system includes a wheel brake for applying a hydraulic braking force to a wheel in response to a hydraulic pressure supplied to the wheel brake, a reservoir is which is stored brake fluid under the atmospheric pressure, a main hydraulic pressure source fluidly connected to the reservoir for generating a high hydraulic pressure in response to a force applied to an operating member of the vehicle, and an auxiliary hydraulic pressure source fluidly connected to the reservoir for generating another high hydraulic pressure. A control valve is fluidly connected to the main hydraulic pressure source, the auxiliary hydraulic pressure source, the wheel brake, and the reservoir for establishing a supply and drain of brake fluid under pressure to the wheel brake from either the main hydraulic pressure source or the auxiliary hydraulic pressure source. A fluid flow control device is provided in a passage connecting the auxiliary pressure source to a control valve to adjust the hydraulic pressure from the auxiliary pressure source to the control valve in two steps. When hydraulic pressure is supplied from the auxiliary pressure source to the wheel brake via the control valve, an increase rate of the hydraulic pressure in the wheel brake can be made quickly or slowly without operating the control valve on high cycles.

摘要： The present invention is directed to a hydraulic brake apparatus for applying braking force to each wheel of a vehicle in response to depression of a brake pedal. An auxiliary pressure source is provided for pressurizing the brake fluid in the reservoir to discharge power pressure. A control piston is slidably disposed in a cylinder body ahead of a master piston to be movable in response to movement thereof, so that a regulator chamber is defined ahead of the control piston, and a rear end thereof is exposed to a pressure chamber. A pressure increase valve is provided for communicating the regulator chamber with the auxiliary pressure source or cutting off the communication in response to movement of the control piston. A pressure decrease valve is provided for communicating the regulator chamber with the reservoir or cutting off the communication in response to movement of the control piston. A resilient member is disposed in the cylinder body for defining a counter-force chamber into which pressure is fed from one of the pressure chamber, auxiliary pressure source and power chamber. The resilient member is adapted to activate the pressure increase and decrease valves to move in a direction opposite to a direction thereof moved by the control piston. A pressure control valve is controlled in response to driving and/or braking conditions of the vehicle to vary the pressure in the counter-force chamber continuously thereby to be regulated into a predetermined pressure.
