Patent number: 8930777Abstract: A method for operating an electronic device that is supplied with electric power by a continuous energy accumulator. A predetermined ending of the first program is monitored in a program step by a second program. If the first program is not switched off as predetermined, the second program generates an error message which is displayed immediately when the device is switched on again.Type: GrantFiled: November 6, 2008Date of Patent: January 6, 2015Assignee: Continental Automotive GmbHInventors: Wolfgang Bay, Michael Henninger

Patent number: 7609021Abstract: The invention relates to a method and to an arrangement for monitoring signals which are guided to a multi-phase motor by an end stage and the pulse width thereof is controlled by a controller. The total of the pulse widths of the signals of each phase is measured by, respectively, a counter, respectively for a predetermined program flow in the controller. The meter reading is read by a counter according to a predetermined period of time and an error signal is produced if the total amount of time exceeds a predetermined tolerance range.Type: GrantFiled: June 13, 2006Date of Patent: October 27, 2009Assignee: Siemens VDO Automotive AGInventors: Wolfgang Bay, Michael Henninger, Sven Kretschmar

Publication number: 20080255745Abstract: In a method for controlling an electromechanical brake of a vehicle, the electromechanical brake having a braking element (12), an electric actuator (14) and a pressing element (18), the pressing element is arranged and is coupled to the electric actuator (14) so that it can be pressed against the braking element (12) by the electric actuator (14). An actual value of a linear acceleration (A_ACT) of the vehicle is determined and the actuator (14) is triggered as a function of the actual value of the linear acceleration (A_ACT) of the vehicle.Type: ApplicationFiled: August 21, 2006Publication date: October 16, 2008Inventors: Wolfgang Bay, Mathias Fernengel, Frank Sader

Patent number: 7242244Abstract: An arrangement for testing a power output stage, with the power output stage includes at least one half bridge with an upper semiconductor switch and a lower semiconductor switch connected in series and to which an operating voltage is applied. A junction point between the semiconductor switches of the at least one half bridge forms an output. A control device performs a test to determine whether the voltage at the output is within a predetermined central tolerance band when the semiconductor switches are not switched on, a test to determine whether the voltage at the output is within a predetermined upper tolerance band when the upper semiconductor switch is switched on, and a test to determine whether the voltage at the output is within a predetermined lower tolerance band when the lower semiconductor switch is switched on. The power output stage is identified as being sound when all of the output voltages are within the respective tolerance bands.Type: GrantFiled: May 10, 2004Date of Patent: July 10, 2007Assignee: Siemens AktiengesellschaftInventors: Wolfgang Bay, Patrick Fischer, Michael Henninger

Patent number: 6584792Abstract: In a method for driving an output stage by pulse-width modulation, which driving serves to supply a unit cooling the output stage during operation, at a higher temperature of the output stage a style of driving is performed which results in a low power loss in the output stage. At a lower temperature of the output stage driving is performed in such a way that the power loss is higher.Type: GrantFiled: April 9, 2001Date of Patent: July 1, 2003Assignee: Mannesmann VDO AGInventor: Wolfgang Bay
