Abstract
A circuit arrangement for a brake system having anti-lock control (ABS) and traction slip control by brake management (BASR) which has an electromotively driven hydraulic pump for the auxiliary pressure supply in the ABS mode and BASR mode, sensors to determine the wheel rotational behavior, and an electronic circuit for analyzing the sensor signals and generating braking pressure control signals. The hydraulic pump, in the BASR mode, is activated by a pulse train (at least temporarily), and the flow rate of the pump is adjusted to the requirements by modulating the pulse train, the requirements being determined by analyzing the traction slip and the instantaneous rotational speed of the hydraulic pump. Pulse patterns in the form of pulse trains with predetermined pulse times and times of pulse break serve to activate the pump.
