<p>In a brake-slip controlled brake system for automotive vehicles, each front wheel is paired with a rear wheel and assigned to a different braking pressure control channel (6, 8; 7, 9). Sensors (S1 to S4) for determining the wheel rotational behaviour are provided one for each wheel. After their electronic combination and processing, the sensor signals serve to govern braking pressure modulators, e.g. solenoid switching valves (6 to 9). In the presence of sufficient friction, i.e. grip, between the front wheels (VR, VL) and the roadway, brake slip control of all the wheels is dependent on the rotational behaviour of the front wheels. In the event of too low friction, brake slip control is switched over to be dependent on the rotational behaviour of at least one of the rear wheels (HR, HL), preferably to the rear wheel having least deceleration which thereby takes the lead as regards the control of the further braking pressure variation. <IMAGE></p> |
