Patent number: 10627440Abstract: A method for detecting arcs in a DC circuit, having a detection conductor, which is routed at least along a conductor of the DC circuit, which carries an electric voltage and is to be monitored. In this connection, a voltage signal that refers to a potential of the DC circuit is coupled into the detection conductor at an incoupling point via a series resistor, the voltage signal is coupled out again at an outcoupling point of the detection conductor, the voltage signal before the series resistor is compared to the voltage signal at the outcoupling point, and a conclusion is drawn that an arc has occurred when the voltage signal at the outcoupling point deviates from the voltage signal before the series resistor by more than a predetermined amount. This invention also relates to a device for carrying out the method. The method and the device permit a quick, reliable detection of an arc in a DC circuit.Type: GrantFiled: June 15, 2015Date of Patent: April 21, 2020Inventor: Peter Herges

Publication number: 20100308647Abstract: A power supply system for a vehicle has at least one control unit with two power supply terminals that are each protected against overload by a fuse. The first power supply terminal is connected to a voltage regulator for the microcomputer of the control unit and to the accumulator via the quiescent current switch, while the second power supply terminal is connected to the accumulator via a fuse. The first power supply terminal supplies the microcomputer with energy, while the second power supply terminal actuates one power switch per control unit in order to supply energy to the output stages of an actuator which is operated by the control unit. The on-board vehicle power system control unit activates the quiescent current switch in order to deactivate the microcomputer, while the power switches of the same control unit are supplied with power.Type: ApplicationFiled: August 30, 2007Publication date: December 9, 2010Applicant: Daimler AGInventors: Sven Fluhrer, Dieter Grohmann, Peter Herges, Frank Huebner, Alexander Lepple, Tobias Raithel

Patent number: 7495580Abstract: The invention relates to an apparatus for finding a parked vehicle again. According to the invention, a portable unit is provided with a pressure sensor whose signals can be evaluated by an evaluation and control unit in order to determine the current air pressure, with the evaluation and control unit evaluating the determined air pressure in order to determine altitude, and storing a first air pressure value as a reference value at a predeterminable first time, which reference value represents an instantaneous altitude of a geographic position of the parked vehicle, with the evaluation and control unit estimating a height difference between a current geographic position of the portable unit and the geographic position of the parked vehicle at a second time, and/or continuously from a pressure difference between the determined current air pressure value and the reference value.Type: GrantFiled: May 25, 2006Date of Patent: February 24, 2009Assignee: Daimler AGInventors: Stefan Albrecht, Roland Fischer, Peter Herges, Joerg Huber, Roland Roessler, David J. Skiff, John A. Wilke

Patent number: 4681185Abstract: Apparatus for the automatic engagement and disengagement of the drive components of a motor vehicle, particularly of the drive of at least one additional axle and/or of locks for auxiliary gear and/or differential gear. The apparatus has sensors for sensing the rotary speeds of the wheels and the steering angle of the vehicle and a control unit which activates the drive components individually, simultaneously or in a given sequence as a function of: The travelling speed; the vehicle acceleration; the slip of the wheels; and the movement condition of the vehicle as a function of the steering angle. The apparatus also has an adaptively operating matching electronic system for accounting for the rotary speeds of the wheels and for the steering angle. An advantage of this apparatus is the engaging of required drive components automatically with narrow limit values and tolerances in necessary situations.Type: GrantFiled: February 11, 1986Date of Patent: July 21, 1987Assignee: Daimler-Benz AktiengesellschaftInventors: Rudolf Hoernig, Peter Herges, Bernd Knoff, Karl-Heinz Richter, Karl-Heinz Buechle, Henning Wallentowitz
