Patent number: 7562946Abstract: A brake regulating system particularly suitable for stabilizing the motion of a commercial vehicle is described, in which a control unit outputs, as a function of a number of input variables, a predefined manipulated variable for the brake pressure of each wheel of a commercial vehicle and/or a predefined manipulated variable for an output variable of the drive engine. For detecting the input variables, the input of the control unit is connected to a steering angle sensor for detecting a steering angle predetermined by the driver, to a sensor system for determining the yaw rate of the commercial vehicle, and to a first acceleration sensor for detecting the transverse acceleration of the commercial vehicle.Type: GrantFiled: November 30, 2001Date of Patent: July 21, 2009Assignee: KNORR-BREMSE Systeme für Nutzfahrzeuge GmbHInventors: Klaus-Dieter Leimbach, Falk Hecker, Oliver Jundt, Herbert Schramm

Publication number: 20070256883Abstract: A toothed belt gearing includes a toothed pulley including pulley teeth having a first configuration and a toothed belt including belt teeth having a second configuration. The belt teeth are meshable with the pulley teeth, the first configuration and the second configuration being different from one another and being selected so as to minimize air present in tooth spaces between meshed ones of the belt and pulley teeth as compared to other toothed belt and pulley combinations which share a substantially same tooth configuration, thereby reducing noise radiation resulting from a resonance behavior of the toothed belt normally present in the other toothed belt and pulley combinations.Type: ApplicationFiled: November 10, 2005Publication date: November 8, 2007Inventors: Martin Budaker, Stefan Froehlich, Klaus-Dieter Leimbach, Wolfgang Reuter, Ralf Duschek, Detlef Beck, Andreas Lay, Torsten Hesse, Michael Yankonis

Patent number: 7249809Abstract: In a method and a device for monitoring a brake system, e.g., a wheel pressure sensor suite of a brake system of a motor vehicle, the fault detection is implemented on the basis of a differential threshold being exceeded by a signal that is representative for the difference of the brake pressures at the individual wheel brakes of a wheel axle. In the process, the differential threshold is set as a function of the averaged rate of increase of the individual pressures at the wheel brakes. Fault detection is carried out on the basis of a model, which takes the instantaneous operating state of the brake system into account.Type: GrantFiled: February 20, 2003Date of Patent: July 31, 2007Assignee: Robert Bosch GmbHInventors: Kai Weeber, Michael Knoop, Klaus-Dieter Leimbach

Patent number: 6871127Abstract: A device for controlling a steer-by-wire steering system in a vehicle, in which redundantly generated sensor signals for regulating a steering motor and for a feedback actuator that transfers the restoring torques from the road to the driver via the steering wheel are received by a control device and plausibility checks of the sensor signals are performed therein and in an operatively associated monitoring module. Microcomputer module and monitoring module monitor each other reciprocally. An auxiliary level for the SbW steering system is monitored by the control device which, in the case of error, switches to this auxiliary level or a mechanical auxiliary level. To further increase safety, the steering wheel motor is triggered via control signals for its phase currents and by a steering wheel motor enable signal, and the steering motor is triggered via control signals for its phase currents and via a steering motor enable signal.Type: GrantFiled: September 29, 2001Date of Patent: March 22, 2005Assignees: Robert Bosch GmbH, ZF Lenksysteme GmbHInventors: Peter Dominke, Chi-Thuan Cao, Wolfgang Pfeiffer, Bo Yuan, Klaus-Dieter Leimbach, Bernd Mueller, Werner Harter, Peter Blessing, Juergen Schuele, Herbert Lohner
