An iso/dump control valve arrangement is associated with each wheel brake of the plurality of wheel brakes. A pump piston is associated with at least one wheel brake of the plurality of wheel brakes. The pump piston is driven by a second electric motor for selectively providing pressurized hydraulic fluid to the iso/dump control valve arrangement. At least one electric brake motor is operative to selectively drive a selected wheel brake. A first electronic control unit is operative to selectively control the first electric motor. A second electronic control unit is operative to selectively control the second electric motor. A third electronic control unit is operative to control the at least one electric brake motor.

摘要： When another pump is actuated while a pump is de-actuated, a pressure adjustment valve is brought into a valve-opened state after a shut-off valve is actuated in a valve-opening direction and the another pump is actuated.

摘要： A control device for a vehicle deceleration device of a vehicle including an electronics unit, with the aid of which a time curve of an input variable predefined by a driver of the vehicle with the aid of an actuation of the brake actuating element is evaluatable and the vehicle deceleration device is activatable taking into account the updated input variable and a characteristic curve, which specifies a relationship between the input variable and a setpoint variable with respect to a setpoint vehicle deceleration to be exerted on the vehicle with the aid of the vehicle deceleration device. The electronics unit detects at least one modulation and/or variation of the input variable triggered by the driver and reestablishes at least one subsection of the characteristic curve taking into account the at least one modulation and/or variation of the input variable (xinput) triggered by the driver.

摘要： A parking brake device includes a fluid unit including: a fluid pump that suctions brake fluid from a master cylinder using a first electric motor; and a pressure regulating valve that increases pressure of the brake fluid discharged by the fluid pump and supplies the increased pressure to a wheel cylinder as a brake fluid pressure, the fluid unit causing the brake fluid pressure to press a friction member against a rotating member fixed to vehicle wheels to generate a braking force, an electrically-powered unit that uses a second electric motor and generates the braking force on a parking wheel on which a parking brake is applied among the vehicle wheels, and a controller that controls the fluid unit and the electrically-powered unit. When the parking brake is actuated, the controller increases only the brake fluid pressure corresponding to the parking wheel in the wheel cylinder.

摘要： A hydraulic brake system of a motor vehicle includes a linear actuator as a driver-independent pressure provision device and a hydraulic valve arrangement between the linear actuator and wheel brakes. In the case of a reduced availability of the linear actuator, a holding mode is carried out, in which the hydraulic pressure in the wheel brakes is shut in with the valve arrangement and a power output of the linear actuator is reduced, the system pressure gradient in the holding mode is measured, and a transition from the holding mode into an alternative mode is carried out based on the system pressure gradient.

摘要： An electropneumatic rail brake system configured to provide emergency braking including an emergency magnet valve which controls air flow into an emergency regulator valve, which valve has an emergency back-up chamber. The emergency regulator provides an output pressure nominally equal to the variable load pressure and no lower than the tare back-up. The magnet valve is closed when energized and when de-energized, pressure is allowed into the emergency back-up chamber, Regulation of the brake cylinder pressure continues during an emergency application such that the brake cylinder pressure applied during an emergency stop does not drop below a predetermined level. In the event of power-loss during an emergency brake stop, the nominal emergency brake pressure is applied to the brake cylinders.
