Patent number: 8843264Abstract: For operation of a motor vehicle (2) having a propulsion system (4), when a critical operating state (STATE_CRIT) occurs and/or an operating error (ERROR) of the motor vehicle (2) and/or of the propulsion system (4) of the motor vehicle (2) occurs, the critical operating state (STATE_CRIT) and/or the operating error (ERROR) are signalled to a driver of the motor vehicle (2) by a reaction of the propulsion system (4) and/or by a reaction of the motor vehicle (2) which can be perceived by the driver.Type: GrantFiled: September 28, 2007Date of Patent: September 23, 2014Assignee: Continental Automotive GmbHInventors: Johannes Feder, Björn Kattentidt, Stefan Maier, Martin Prenninger

Patent number: 8359137Abstract: For the operation of a motor vehicle (2), when a critical (CRIT) operation state (STATE) of the motor vehicle (2) and/or a drive system (4) of the motor vehicle (2) is detected in which an operation error (ERROR) can occur, a driver of the motor vehicle (2) is signaled (SIG) that there is a critical (CRIT) operation state (STATE). When the operation error (ERROR) occurs, the system is switched into a limited operation (LIMIT) of the drive system (4).Type: GrantFiled: January 16, 2008Date of Patent: January 22, 2013Assignee: Continental Automotive GmbHInventors: Johannes Feder, Björn Kattentidt, Stefan Maier, Martin Prenninger

Patent number: 8200387Abstract: In a method for controlling the operation of an internal combustion engine, a target torque to be produced is determined in several steps: In a first step a torque requested by a user is determined and modified in subsequent steps by different functions, which reproduce the influences of at least one continuously determined working and/or operating parameter of the engine on the torque that is actually produced, in such a way that at the end of the steps the target torque required during the engine operation is defined and the engine operation and the determination of the working and/or operating parameter are monitored for errors. If errors occur, diagnostic values that describe or indicate the errors are generated and used to modify, in particular limit the target torque. The diagnostic values are individually assigned to the individual steps to modify the determination or modification of the torque performed in each step.Type: GrantFiled: May 20, 2008Date of Patent: June 12, 2012Assignee: Continental Automotive GmbHInventors: Stefan Maier, Martin Prenninger

Patent number: 7222046Abstract: Devices and methods are used for ascertaining wheel positions of wheels on a wheeled vehicle. Separate wheel units are connected to each other via a vehicle bus and via an additional supply lead, so that for the purposes of learning the separate wheel units, the separate wheel units are connected to the supply lead successively in a predetermined sequence and provided with a new, individual identity code, or subjected to a wheel-unit-specific dc voltage potential as an identity code by using at least one additional connection.Type: GrantFiled: April 19, 2005Date of Patent: May 22, 2007Assignee: Siemens AktiengesellschaftInventors: Martin Fischer, Manfred Fröhler, Franz Hillenmayer, Matthias Münch, Martin Prenninger, Dieter Wagner, Gero Wuttke

Patent number: 7130768Abstract: In control systems (5) for internal combustion engines (14) in motor vehicles it is known that fault diagnoses are carried out to ensure the functional reliability of the internal combustion engine (14) or the motor vehicle even in the event of a fault. If a fault symptom (1) occurs, the cause of the fault is determined and a diagnosis manager (3) is used as a rule to deactivate the defective control system (5) completely or to initiate an emergency operation function. It is proposed that all information relating to fault symptoms should be listed, the actual cause should be determined by comparison with stored fault profiles and as a result only the smallest possible restriction of the functions of the relevant control systems (5) should be initiated. This has the advantage that the control system (5) can as a rule continue to be operated despite their restricted functional scope.Type: GrantFiled: October 18, 2004Date of Patent: October 31, 2006Assignee: Siemens AktiengesellschaftInventors: Carl-Eike Hofmeister, Michael Käsbauer, Martin Prenninger

Patent number: 7024318Abstract: In a tire pressure measurement system a display indicating whether a tire (1) has an inadmissible or incorrect tire pressure and which tire (1) has inadequate tire pressure, is only activated when the driver stops to refuel. One or more sensors (6) are located near to the tank for this purpose and these identify a fuel stop.Type: GrantFiled: September 10, 2002Date of Patent: April 4, 2006Assignee: Siemens AktiengesellschaftInventors: Frank Fischer, Dominik Fuessel, Martin Prenninger, Martin Fischer, Franz Hillenmayer

Patent number: 6980099Abstract: The arrangement for monitoring at least one parameter for a number of motor vehicle wheels uses at least one receiver antenna that features a directional characteristic such that at least the signals which are transmitted by detector units located at two different vehicle wheels can be uniquely assigned to the relevant wheel positions as a result of the different receive level. The use of a number of receiver antennas allows either the number of distinguishable detector units to be increased or a redundancy to be created to improve the reliability of the detection.Type: GrantFiled: June 25, 2003Date of Patent: December 27, 2005Assignee: Siemens AktiengesellschaftInventors: Johannes Kroitzsch, Jürgen Spotka, Martin Prenninger

Patent number: 6748799Abstract: A method of monitoring a tire pressure, comprises the steps: measuring at least one parameter that influences the tire pressure, calculating the optimum tire pressure &rgr;opt on the basis of the at least one measured parameter, comparing a measured tire pressure p with the optimum tire pressure &rgr;opt in order to generate a deviation signal in the event of a predetermined deviation.Type: GrantFiled: September 10, 2002Date of Patent: June 15, 2004Assignee: Siemens AktiengesellschaftInventors: Frank Fischer, Dominik Fuessel, Martin Prenninger, Martin Fischer, Franz Hillenmayer

Patent number: 6690271Abstract: A device for monitoring at least one parameter for vehicle wheels includes, on each wheel, a detector unit having a transmitter unit that respectively transmits a phase-modulated or frequency-modulated signal to a central evaluation and control unit. Each detector unit transmits, at specific time intervals, a brief signal that contains a uniquely defined identifier. After a wheel is changed, a renewed assignment of the detector unit to the respective wheel positions can be carried out in an assignment mode of the detector unit and of the control unit, by registering a profile of the mean reception power for each detector unit as a function of the angular position of the respective wheel and comparing such signature profile with stored signature information. The comparison can be carried out by cross-correlating the two respectively decisive curves, or by comparing individual values or specific characteristic variables of the profiles.Type: GrantFiled: July 24, 2002Date of Patent: February 10, 2004Assignee: Siemens AktiengesellschaftInventors: Martin Fischer, Dominik Füssel, Martin Prenninger

Publication number: 20040021562Abstract: Tire modules (3) are assigned to wheel positions when the wheel speed is above a threshold value. Each tire module (3) transmits a number of signals together with at least one tire-specific identifier over a predetermined period. An antenna (5) positioned asymmetrically in respect of the wheel positions receives the intensity patterns based on wheel rotation and compares these intensity patterns with reference models. In the case of at least broad correspondence with a specific reference model the respective intensity pattern and the associated identifier are assigned to a wheel position.Type: ApplicationFiled: May 23, 2003Publication date: February 5, 2004Inventor: Martin Prenninger
