Brake equipment comprising a hydraulic, single- or multi-circuit braking system of a land vehicle having an electric drive for executing a regenerative braking of the land vehicle by means of at least one electric machine in or on the drive train of the vehicle and also a braking of the land vehicle by means of at least one wheel brake. A brake pedal and at least one sensor are used to detect a braking requirement of the driver. A master cylinder is used to supply pressurized hydraulic fluid into at least one brake circuit that supplies at least one wheel brake in accordance with the braking requirement. Associated with at least one brake circuit is an electrohydraulic control unit comprising at least a first connection for hydraulic fluid and at least a second connection for hydraulic fluid. An electronic control unit controls components of the electrohydraulic control unit such as a hydraulic pump and switching valves as a function of a braking requirement and/or sensor signals that represent ambient quantities or characteristic quantities coming from the braking system. A regenerative brake unit has at least a first connection for hydraulic fluid and at least a second connection for hydraulic fluid and is hydraulically coupled into at least one of the brake circuits between the master cylinder and at least one of the wheel brakes. The regenerative brake unit is actuated by the electronic control unit to bring about the effect that, in the event of a regenerative braking operation, the volume of hydraulic fluid corresponding to the braking requirement is not supplied into the wheel brakes, but is stored. |
