Abstract
An electrohydraulic brake for a vehicle, which includes an electronic controller having an implemented regulation function, which is carried out during a braking operation as needed in at least one regulating cycle, wherein during the regulating cycle, at least one brake pressure reduction and at least one brake pressure build-up take place in at least one hydraulic brake actuator. The electrohydraulic brake includes a hydraulic fluid reservoir, a pump, and at least one pressure accumulator. The electronic controller controls at least the drive machine for the pump and/or the valve device.
Claims17
An electrohydraulic brake for a vehicle, comprising:
- a) an electronic controller having an implemented regulation function, which is carried out during a braking operation as needed in at least one regulating cycle, wherein during the regulating cycle, at least one brake pressure reduction and at least one brake pressure build-up take place in at least one hydraulic brake actuator,
- b) the at least one hydraulic brake actuator, which generates a braking force depending on the introduced brake pressure,
- c) a hydraulic fluid reservoir for depressurized storage of hydraulic fluid,
- d) a pump and a drive machine for the pump,
- e) at least one pressure accumulator for pressurized storage of hydraulic fluid which originates from the hydraulic fluid reservoir,
- f) flow connections between the at least one brake actuator, the hydraulic fluid reservoir, the pump, and the pressure accumulator, wherein
- g) in at least one flow connection, a valve device at least partially controllable by the electronic controller is arranged, which controls a flow of hydraulic fluid in the at least one flow connection, wherein
- h) the electronic controller controls at least the drive machine for the pump and/or the valve device such that during the at least one regulating cycle, hydraulic fluid flows back and forth or is conveyed back and forth between the at least one brake actuator and the pressure accumulator.
