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

Patent number: 6370471Abstract: The invention concerns a system for automatic following guidance, particularly for heavy-traffic automatic following guidance, of a motor vehicle (1), designed to ease the burden on the driver in heavy-traffic situations both by taking over lateral guidance by means of an automatic steering regulation system and by maintaining a set distance from a leading vehicle. The latter function requires an adaptive cruise and braking regulation system with “stop” and “go” function. According to the invention, selection and decision means (5, 6, 7, 8, 9) are provided that select both the regulating parameters and the types of controllers [sic], e.g., following guidance of the motor vehicle (1) on the basis of lane markings recognized by means of a video camera or on the basis of a recognized leading vehicle.Type: GrantFiled: January 8, 2001Date of Patent: April 9, 2002Assignee: Robert Bosch GmbHInventors: Herbert Lohner, Peter Dominke, Chi-Thuan Cao, Klaus-Dieter Leimbach, Werner Harter, Mathias Hommel

Patent number: 6219604Abstract: A steer-by-wire steering system comprised of an electronically regulated steering positioner mounted to the steering gear of the front axle or to both front wheels of a vehicle together with an electronic steering regulator and a feedback actuator. A sensor senses the driver's selected direction from the steering wheel. Road feedback can be relayed to the driver through a feedback actuator via the steering wheel. The loss of road feel caused by the absence of the steering column, which normally strongly influences the driver's directional wish, is recreated by the feedback actuator.Type: GrantFiled: December 28, 1999Date of Patent: April 17, 2001Assignee: Robert Bosch GmbHInventors: Elmar Dilger, Peter Ahner, Herbert Lohner, Peter Dominke, Chi-Thuan Cao, Ngoc-Thach Nguyen, Helmut Janetzke, Thorsten Allgeier, Wolfgang Pfeiffer, Bo Yuan, Bernd Muller, Klaus Ries-Mueller, Werner Harter, Thomas Sauer, Werner Hess, Peter Blessing

Patent number: 5448561Abstract: An improved method for exchange of data in data processing installations, especially Controller Areas Networks (CAN), permits acknowledged and segmented transmission of data strings, of arbitrarily long length, between at least two stations in the network or other data processing installation. The method includes the transmission of the messages associated with the data by means of frames; the frames contain a header field and a data field. In the event of contention between multiple stations of the data processing installation for access to the bus connection, which frame has priority is determined by evaluating the respective header fields. In the data field of the frame, there is a control information field (58, 95) containing a message code which serves to identify the message type. The message codes distinguish among activation messages (AR, AC), data messages (DT), and acknowledgement (AK) messages. This permits transmission of data strings, of limited length, with acknowledgement.Type: GrantFiled: September 16, 1992Date of Patent: September 5, 1995Assignee: Robert Bosch GmbHInventors: Karl-Heinz Kaiser, Herbert Lohner, Hans-Joerg Mathony, Jan Unruh, Uwe Zurmuehl, Udo Brunke, Juergen Glasser, Olaf Linne

Patent number: 5105441Abstract: A device for potential-free transmission of dominant and recessive data bits in a bus system operating with bit-by-bit arbitration includes a series connection of a modulator, a galvanic separation circuit, and a demodulator. Data bits to be transmitted are scanned in the modulator at equidistant time intervals and are divided into two intermediate trains of data bits wherein the dominant bits alternate with the recessive bits. The two intermediate trains are applied to two input terminals of a galvanic separating device, and a demodulation is effected on the output side of the separating device.Type: GrantFiled: March 7, 1989Date of Patent: April 14, 1992Assignee: Robert Bosch GmbHInventors: Wolfgang Borst, Wolfgang Botzenhardt, Siegfried Dais, Otto Karl, Uwe Kiencke, Martin Litschel, Herbert Lohner
