Abstract
A method of operation of an electronically controllable brake actuation system for anti-lock automotive vehicle brake systems employs a brake system which includes a master brake cylinder operable by an actuating pedal, braking pressure generators which are electromechanically operable by an electronic control unit. The braking pressure generators are directly connected to wheel brakes of a vehicle and are connectable to the master brake cylinder by way of hydraulic connections closable by valves that are electromagnetically operable by the electronic control unit. The system also includes at least one sensor device for identification of the driver wish for deceleration, and at least one simulator chamber interacting with the master brake cylinder. On commencement of a braking operation, a signal representative of the position of the master brake cylinder piston and a signal representative of the actuating speed occurring on the actuating pedal are produced. A length of the time delay, after which the valves are closed upon commencement of the braking operation, is determined by the electronic control unit responsive to at least one of the signals.
