Patent number: 9132815Abstract: Disclosed is a brake actuation unit for actuating a ‘brake-by-wire’ type brake system for a motor vehicle. The brake system includes a brake booster operable via a brake pedal mounted on a shaft and via an electronic control unit depending on the driver's request, and an element to decouple a force-transmitting connection between the brake pedal and the brake booster in the ‘brake-by-wire’ operating mode. Also included are a device to detect a deceleration request of the driver, and a pedal travel simulator which interacts with the brake pedal and is formed of a simulator spring, which is arranged in terms of effect between a force-transmitting part connected to the brake pedal and a simulator housing, which is mounted on the shaft by means of two bearings. The simulator housing (22) includes a cylindrical area (26) for the accommodation of the two bearings (27, 28). This measure renders it possible to reduce the deformations that occur during actuation of the pedal travel simulator to a great extent.Type: GrantFiled: August 3, 2006Date of Patent: September 15, 2015Assignee: Continental Teves AG & CO., OHGInventors: Holger Von Hayn, Jurgen Schonlau, Manfred Ruffer, Thomas Sellinger, Torsten Queisser, Lazar Milisic

Publication number: 20130113271Abstract: Disclosed is a brake actuating unit for actuating a motor vehicle brake system of the ‘brake-by-wire’ type. The system includes a brake booster which is operable in response to the driver's wish both by a brake pedal and by an electronic control unit. A device is provided to decouple a force-transmitting connection between the brake pedal and the brake booster in the ‘brake-by-wire’ operating mode. A master brake cylinder connected downstream of the brake booster, a device to detect a deceleration request of the driver, and a pedal travel simulator which interacts with the brake pedal and due to which a resetting force acting on the brake pedal can be simulated in the ‘brake-by-wire’ operating mode independently of an actuation of the brake booster, and which can be enabled in the ‘brake-by-wire’ operating mode when the force-transmitting connection between the brake pedal and the brake booster is decoupled and can be disabled outside the ‘brake-by-wire’ operating mode.Type: ApplicationFiled: May 2, 2012Publication date: May 9, 2013Inventors: Holger von Hayn, Jürgen Schonlau, Manfred Rüffer, Wolfgang Ritter, Holger Kranlich, Jose Gonzalez, Thomas Sellinger, Milan Klimes, Torsten Queisser, Michael Haber

Patent number: 8392085Abstract: A motor vehicle includes an electrohydraulic brake system with driving dynamics control, a master brake cylinder (1), wheel brakes (75-78), and at least one pressure fluid supply device (94, 95) actuated by an electronic control unit. The pressure can be applied to the wheel brakes (75, 76, 77, 78) of the vehicle which are also connectable to the master brake cylinder (1) by way of a closable hydraulic connection (73, 74). A device for detecting a brake application includes a magnet (35) as a signal transmitter and a sensor element (36). The sensor element (36), upon piston movement of the master cylinder (1), senses a change in the magnetic field and outputs a digital signal and an analog signal. The two signals are passed on to an electronic control unit and are evaluated in the electronic control unit.Type: GrantFiled: December 8, 2004Date of Patent: March 5, 2013Assignee: Continental Teves AG & Co. oHGInventors: Jürgen Schonlau, Manfred Rüffer, Dieter Merkel, Oliver Kugland, Torsten Queisser, Thomas Voigtmann
