ABSTRACT:
The invention relates to an electronically regulatable vehicle brake system with traction control, in which a master cylinder is connected indirectly via a hydraulic unit to at least one wheel brake. The hydraulic unit has electromagnet valves and an externally triggerable pressure generator, for modulating the wheel brake pressure, optionally independently of the driver. For preventing wheel slip, the pressure generator is connected by its intake side to an intake conduit, among other things, that is controllable by an intake valve. To enhance the dynamics and improve the regulatability of a vehicle brake system, a self-aspirating pressure fluid storage unit is connected to the intake conduit and makes an aspiration volume available to the pressure generator.
