Patent number: 8950827Abstract: A brake device for motor vehicles has at least two hydraulic brake circuits which are directly connected to a master brake cylinder, as well as an additional brake circuit, which is able to be actuated via a control device, independently of the master brake cylinder. Because of the separate hydraulic brake circuits in the region of the front axle, redundancy is provided, while the third brake circuit, that is able to be actuated independently of the master brake cylinder and typically acts on the rear wheels, during automatic actuation, permits taking into account a braking effect by additional active assemblies, such as a driven generator.Type: GrantFiled: April 20, 2009Date of Patent: February 10, 2015Assignee: Robert Bosch GmbHInventors: Gebhard Wuerth, Volker Mehl, Michael Kunz, Matthias Leiblein, Werner Quirant

Patent number: 8870300Abstract: A method for actuating a hydraulic vehicle brake system, includes a master brake cylinder with a preferably electromechanical brake booster and a wheel slip control device. The master brake cylinder is actuated simultaneously with the brake booster, and hydraulic pumps of the wheel slip control device are driven by an electric motor. Pressure builds more quickly in the wheel brakes of the vehicle brake system for safety and assistance functions that require high pressure build-up dynamic. The method also increases the wheel brake pressure using the pressure that can be generated by actuating the master brake cylinder with the brake booster.Type: GrantFiled: June 25, 2010Date of Patent: October 28, 2014Assignee: Robert Bosch GmbHInventors: Herbert Vollert, Remy Garnier, Reinhard Weiberle, Timo Jahnz, Volker Mehl, Frank Kneip, Dirk Mahnkopf, Jens Kolarsky, Stephan Hoenle

Publication number: 20120161507Abstract: A method for operating a hydraulic vehicle braking system having an electromechanical brake booster is disclosed. A shut-off valve that is located between a brake master cylinder and wheel brakes is closed to maintain a wheel-brake pressure and thus a braking force. To maintain a constant braking force, no current must be applied to an electric motor of the brake booster. The vehicle braking system can be used as a parking brake. The shut-off valve is present if the vehicle braking system has an anti-lock control device.Type: ApplicationFiled: December 14, 2009Publication date: June 28, 2012Applicant: ROBERT BOSCH GMBHInventors: Herbert Vollert, Remy Gaarnier, Reinhard Weiberle, Time Jahnz, Volker Mehl, Frank Kneip, Dirk Mahnkopf, Jens Kolarsky, Stephan Hoenle
