摘要： A system for and a method of controlling driving of a continuously-operable electronic vacuum pump includes determining conditions for allowing and disallowing first and second electronic vacuum pumps to operate for each braking situation according to vehicle state information associated with braking. The first and second electronic vacuum pumps are driven individually or concurrently according to the determined braking situation. Thus, an optimal negative pressure optimal suitable for the vehicle state information is easily supplied to a booster.

摘要： A control device is provided with a flow rate derivation part for deriving a pressure-holding-valve flow rate on the basis of a pressure command value and a previous pressure command value; a differential pressure derivation part for deriving a differential-pressure-valve differential pressure value so that the differential-pressure-valve differential pressure value increases with an increase in the difference obtained by subtracting the pressure-holding-valve flow rate from a pump-discharge flow rate; and a pressure-holding-valve processing part for performing an aperture derivation process to derive a command aperture so that the command aperture decreases with an increase in the difference obtained by subtracting the pressure command value from the sum of an pressure value and the differential-pressure-valve differential pressure value, and driving a holding pressure valve at the command aperture.

The hydraulic control device includes a rear-side connection fluid path, a front-side connection fluid path, a first discharge fluid path, a first hydraulic source, a second discharge fluid path, a second hydraulic source, and a shutoff valve. The rear-side connection fluid path connects a master cylinder with a rear-side wheel cylinder. The front-side connection fluid path connects the master cylinder with a front-side wheel cylinder. The first discharge fluid path is connected to the rear-side connection fluid path and to the front-side connection fluid path. The first hydraulic source is configured to discharge a brake fluid to the first discharge fluid path. The second discharge fluid path is connected to the front-side connection fluid path at a position between a connecting position of the first discharge fluid path and the front-side wheel cylinder. The second hydraulic source is configured to discharge the brake fluid to the second discharge fluid path. The shutoff valve is placed between the connecting position of the first discharge fluid path and a connecting position of the second discharge fluid path in the front-side connection fluid path.

摘要： It is an object of the invention to provide a brake device capable of detecting a failure in each of components, by which booster control is performed, at an early stage even during vehicle running. The brake device is configured to discharge brake fluid into a communicating fluid path that connects a fluid path of a primary system and a fluid path of a secondary system, and to control a first communicating valve for restricting a flow of brake fluid from the communicating fluid path to the fluid path of the primary system and a second communicating valve for restricting a flow of brake fluid from the communicating fluid path to the fluid path of the secondary system in respective valve-closing directions, so as to check at least a state of the pump.

摘要： In a braking control apparatus, a plurality of pumps are driven by a common first motor. A brake supplies operating fluid to pipelines by operating the first motor, and controls opening/closing of a fluid pressure regulating valve so as to make the wheel cylinder pressure in the right front wheel approach the right front wheel target pressure, and controls opening closing of a fluid pressure regulating valve so as to make the wheel cylinder pressure in the left rear wheel approach the left rear wheel target pressure. In the case where the right front wheel target pressure is zero when the fluid pressure regulating valve is to be opened so as to make the wheel cylinder pressure in the left rear wheel approach the left rear wheel target pressure, the brake turns off the first motor.
