Patent number: 10000191Abstract: A brake system for a vehicle having a master brake cylinder, which provides a pressure signal, having a brake-medium reservoir connected to the master brake cylinder, and a first brake circuit, which is coupled by a first input to the master brake cylinder and by a second input to the brake-medium reservoir, and having at least one first wheel-brake cylinder, which is mounted at a first wheel, in order to exert a force corresponding to the pressure signal onto the first wheel, and having a separator valve, which is configured between the first input and the first wheel-brake cylinder, to prevent further transmission of the pressure signal upon receipt of a supplied closing signal; and having a control valve, which is configured between the first input and the first wheel-brake cylinder; in order to control an inflow of a brake medium from brake-medium reservoir to the first wheel-brake cylinder. In addition, a method for controlling a corresponding brake system is also described.Type: GrantFiled: March 20, 2017Date of Patent: June 19, 2018Assignee: ROBERT BOSCH GMBHInventors: Gebhard Wuerth, Volker Mehl, Michael Kunz, Matthias Leiblein, Werner Quirant

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: 8770673Abstract: In a brake device for a motor vehicle having a first and a second hydraulic brake circuit, the second brake circuit is decoupled from the main brake cylinder in partial braking operations, and is operated with the aid of a pressure accumulator controlled by a control device, which takes an additional deceleration effect due to an active power component, e.g., a generator, into account.Type: GrantFiled: April 21, 2009Date of Patent: July 8, 2014Assignee: Robert Bosch GmbHInventors: Gebhard Wuerth, Volker Mehl, Michael Kunz, Matthias Leiblein, Werner Quirant

Patent number: 8651586Abstract: In a braking device for a motor vehicle having a first group and a second group of brake circuits, each brake circuit being associated with one group of wheels, and at least the first group of brake circuit being implemented as hydraulic brake circuits, at least one group of wheels being connected to at least one operating unit, which may cause a deceleration of the wheels, the task of a comfortable connection of recuperation brake applications to conventional brake applications is achieved in that a control unit controls the brake application of the brake circuit or circuits of the second group and optionally the deceleration effect of the operating unit or assemblies, the first group of brake circuits being activatable directly by the driver using a brake operating unit.Type: GrantFiled: May 25, 2009Date of Patent: February 18, 2014Assignee: Robert Bosch GmbHInventors: Gebhard Wuerth, Volker Mehl, Michael Kunz, Matthias Leiblein, Werner Quirant

Publication number: 20110272228Abstract: A brake system for a motor vehicle having an at least single-circuit brake cylinder with the aid of which a brake force may be applied to at least one wheel of the motor vehicle when actuated. The brake cylinder is mechanically operatively connected to a booster cylinder, which is decoupled from brake setpoint detector and is hydraulically triggerable for actuation of the brake cylinder corresponding to the driver's intent as detected with the aid of the brake setpoint detector. A motor vehicle having a brake system is also described.Type: ApplicationFiled: October 16, 2009Publication date: November 10, 2011Inventors: Michael Kunz, Matthias Leiblein, Werner Quirant, Jens Kolarsky
