  • Patent number: 8365579
    Abstract: An apparatus for furnishing an amplified sensor signal of a knock sensor, encompassing an analog amplifier for amplifying the sensor signal in accordance with a first definable gain factor; an analog/digital converter for digitizing the amplified sensor signal into a digitized sensor signal; a digital amplifier for amplifying the digitized sensor signal in accordance with a second definable gain factor; and a control unit in order to furnish the first and the second gain factor as a function of a baseline sound level of the sensor signal, the baseline sound level corresponding to the component of the solid-borne sound signal generated in normal operation without knocking.
    Type: Grant
    Filed: September 24, 2008
    Date of Patent: February 5, 2013
    Assignee: Robert Bosch GmbH
    Inventors: Kai Dierssen, Stefan Kempf, Jochen Goebels, Federico Buganza, Anton Kantschar, Frédéric Gabel, Carsten Kluth, Oskar Torno, Werner Haeming, Robert Sloboda, Jan Boettger, Rudi Eichhorn, Andreas Meinken

  • Patent number: 7051712
    Abstract: A method for computing an ignition angle of an internal combustion engine as a function of the operating conditions of the engine and knock signals K, which indicate knocking combustion in the engine. If knock occurs, the ignition angle is retarded. If knock stops for a first period, the ignition angle is advanced again. Advance of the ignition angle is limited on the basis of the first period. If knock stops for a second period, which exceeds the first period, the ignition angle is further advanced.
