  • Method for diagnosing a differential pressure sensor situated in an air duct of an internal combustion engine
    Patent number: 9470600
    Abstract: A method for diagnosing a differential pressure sensor situated in an air duct of an internal combustion engine, including: selecting a tolerance range for an output signal of the differential pressure sensor, within which a predetermined pressure difference is to be interpreted; and ignoring an error, in which the output signal of the differential pressure sensor falls out of the tolerance range, if, first of all, a predetermined operating situation prevails, in which the predetermined pressure difference is considered to be applied to the differential pressure sensor, and secondly, a disturbance pressure is detected in the air duct.
    Type: Grant

    Date of Patent: October 18, 2016
    Assignee: ROBERT BOSCH GMBH

  • Method for correcting an offset for a pressure difference measured using a differential pressure sensor situated in an air duct
    Patent number: 9291519
    Abstract: A method for correcting an offset for a pressure difference measured using a differential pressure sensor situated in an air duct. The offset is computed using an output signal of a pressure sensor, including: transferring the air duct into a predetermined operating situation in which a predetermined pressure difference is considered to be applied to the differential pressure sensor, measuring a level of the output signal in the predetermined operating situation, and computing the offset based on the measured level of the output signal.
