Patent number: 9205789Abstract: A method for avoiding error messages due to maintenance work on a vehicle, which are generated by a monitoring unit if one or multiple operating parameters of a monitored vehicle system are outside of a predefined, admissible value range. Accordingly, the general driving operation is monitored with the aid of a vehicle's own sensor system with respect to a maintenance state and, if a maintenance state is established, the admissible value range be automatically extended or at least one operating parameter is ignored during monitoring.Type: GrantFiled: January 11, 2011Date of Patent: December 8, 2015Assignee: ROBERT BOSCH GMBHInventors: Gebhard Wuerth, Michael Kunz, Ralf Kinder, Thilo Stephan

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: 6149251Abstract: A device and a process for controlling the braking force at at least one wheel of a vehicle include at least a first arrangement for determining a criterion which describes and/or influences the vehicle movement, a second arrangement for determining a variable which describes the wheel dynamics of the wheel in question, and a third arrangement with which it is determined, at least as a function of the criterion which was determined, whether a driver-independent brake intervention at a wheel is foreseeable. Furthermore, the device and the process contain a fourth arrangement with which a slight activation of the actuators assigned to the wheel, with variable duration, can be performed if the requirement of a foreseeable driver-independent brake intervention is met, this activation occurring before this driver-independent brake intervention. The duration of the slight activation of the actuators is determined at least as a function of the variables which describe the wheel dynamics of the wheel in question.Type: GrantFiled: March 4, 1998Date of Patent: November 21, 2000Assignee: Robert Bosch GmbHInventors: Gebhard Wuerth, Elmar Mueller, Frank Leibeling, Dieter Schuetz
