  • Method for verifying the plausibility of a measuring device for determining the quality of an aqueous urea solution in a reservoir of an SCR catalyst system
    Patent number: 9239320
    Abstract: A method for verifying the plausibility of a measuring device for determining a quality of an aqueous urea solution in a reservoir of an SCR catalyst system comprises determining whether a filling of the reservoir has taken place, determining the quality of the aqueous urea solution in the reservoir and detecting whether an error of the measuring device is present or whether the reservoir was filled with an aqueous urea solution, the quality of which deviates from a default value consisting of a filling status of the reservoir and the quality of the aqueous urea solution in said reservoir.
    Type: Grant
    Filed: May 31, 2013
    Date of Patent: January 19, 2016
    Assignee: Robert Bosch GmbH
    Inventors: Wolfgang Klenk, Matthias Burger, Reinold Weinmann, Wilhelm Dueck
  • Method for checking the plausibility of the signals of a tank filling level sensor
    Patent number: 8649934
    Abstract: A method for checking the plausibility of the signals of a tank filling level sensor of a motor vehicle (120) is characterized in that the roadway inclination of the roadway (130) which is traveled on by the motor vehicle (120) is determined, and definitive information about the possibility of using the signals of the tank filling level sensor is obtained as a function of the roadway inclination (N).
