Abstract
A hydraulic vehicle brake system includes at least one brake circuit, at least one wheel brake, and a pressure-generating unit. The pressure-generating unit is configured to supply the wheel brake with pressure medium under brake pressure, or to adapt the brake pressure to slip conditions of a wheel assigned to the wheel brake. A feed volume of the pressure medium of the pressure-generating unit is controllable according to a pressure medium volume demand. The pressure-generating unit includes at least two pumps that feed into a common pressure line, and an electronically actuated mechanism configured to control a pressure medium connection from the pressure line and a suction side of at least one of the pumps as a function of the demand.
Claims7
An electronically slip-controlled vehicle brake system comprising:
- one or more brake circuits;
- at least one wheel brake connected to each of the one or more brake circuits;
- and
- a respective drivable pressure-generating unit for each of the one or more brake circuits, the respective drivable pressure-generating unit configured to (i) supply the at least one wheel brake (4-6) connected to each brake circuit with pressure medium under a brake pressure or (ii) adapt the brake pressure to the slip conditions of a wheel assigned to the at least one wheel brake connected to each brake circuit, and the respective drivable pressure-generating unit including:
- at least two pumps configured to deliver pressure medium into a shared pressure line, and
- an electronically controllable mechanism configured to control a pressure medium connection from the shared pressure line to a suction side of at least one of the pumps depending on the as a function of a pressure medium volume demand of the at least one wheel brake connected to each brake circuit.
