Patent number: 10800388Abstract: A method for operating a motor vehicle brake installation. An electrically controllable pressure modulation device having a pump-valve arrangement is hydraulically arranged between the primary brake system and the front axle brakes. The pump-valve arrangement includes, for each front brake, a first valve, arranged between the inlet valve of the primary brake system and the brake, and an electrically activatable pump, with a suction and pressures ports. The pressure port is connected to the brake. In the presence of a predetermined condition of the primary brake system and of an actuation of the master brake cylinder by the driver, a build-up of brake pressure at the front axle brakes is performed by the pump-valve arrangement. The pressure set by the pump-valve arrangement is higher than the brake pressure in the master brake cylinder, whereas the brake pressure of the master brake cylinder prevails at the brakes of the rear axle.Type: GrantFiled: February 20, 2017Date of Patent: October 13, 2020Assignee: Continental Teves AG & Co. oHGInventors: Marco Besier, Georg Roll, Sascha Gröger, Andreas Neu, Cristiano Hoffmann

Patent number: 8577506Abstract: A control valve conditioning method in an electrohydraulic pressure control unit comprising at least one electrically triggered solenoid valve that is controlled in an analog manner. The solenoid valve is operated at a specific operating current according to a functional correlation or characteristic diagram between the valve current and the differential pressure characteristic curve when the pressure is controlled, said functional correlation or characteristic diagram being stored in the pressure control unit. The method comprises the following steps: a) temporarily applying at least one anti-hysteresis pulse to the solenoid valve during which a current is set far below or far above the operating current in the valve; b) applying the anti-hysteresis pulse at the desired operating current before or during controlled operation, and c) applying the anti-hysteresis pulse wherein the duration is limited in such a way that the anti-hysteresis pulse has largely no influence on the brake pressure.Type: GrantFiled: January 8, 2009Date of Patent: November 5, 2013Assignee: Continental Teves AG & Co. oHGInventors: Andreas Neu, Ralph Gronau, Holger Kollmann, Peter Leska, Jörg Berntheusel, Tobias Franke, Michel Wagner, Jusuf Muratoski, Artur Kost, Dieter Burkhard
