    • A method is proposed for improving the control characteristics ofa brake pressure regulation system for vehicles and involves the following: the turning characteristics of the individual vehicle wheels are determined with wheel sensors, a vehicle reference speed (approximately equal to the vehicle speed) and vehicle reference acceleration are determined by logical connection and evaluation of the sensor signals, a brake pressure control signal is formed and brake pressure control signals are generated in accordance with a predetermined regulation mode, and vehicle acceleration sensors are used to determine vehicle body acceleration. The difference between the vehicle reference acceleration (aref; 13) and car body acceleration (aKar; 14) is determined and evaluated to ascertain the road conditions at a given moment. The regulation mode or algorithm is then varied in accordance with the difference signal ( DELTA ; 16).

    • The invention concerns a drive slip-controlled hydraulic braking system comprising an active braking device and provided with an inlet pressure generator (17) which builds up inlet pressure in a brake circuit via a connection (5) to the reservoir of the master cylinder (1). To this end, disposed at a reservoir connection (5) is a valve which comprises a valve chamber (7) with a vertically rectilinear wall (11), inside which a valve body (12) is disposed so as to be axially displaceable. Above the valve body (12), the valve chamber (7) has an opening (13) to a reservoir space (6) in the pressurized medium reservoir (2). Below the valve body (12) a tube (16), which is connected to the delivery side of a pre-charging pump (17), leads into the valve chamber (7). The upper end (9) and the lower end (10) of the valve chamber (7) are connected by a bypass (8) in front of which the valve body (12) is displaced when the pre-charging pump (17) is operating, the valve body (12) simultaneously closing the opening (13) to the reservoir space (6). Thus, the pre-charging pump (17) can build up inlet pressure below the valve body (12) in the valve chamber (7), the inlet pressure spreading into the associated braking circuit via the reservoir port (3) and the master cylinder (1), whilst a pump in the braking circuit can automatically draw pressurized medium out of the reservoir space (6) via the bypass (8).
