Patent number: 10533980Abstract: A measured value of a sensor element is obtained during repeatedly executed measuring periods for performing different measurements and for setting different operating states, the sensor element being electrically connected in a periodically alternating manner, in consecutive switching positions, in a predefined order, where at least one measurement for determining the measured value is performed repeatedly within a measuring period for determining individual values at predefined switching positions, the measured value being determined from the individual values. Using the switching position within the measuring period, the operating state of the sensor element preceding the individual measurement, and therefore, the influence of the preceding circuit configuration on the individual measured value, is known, and the individual values are correspondingly corrected. By correcting the individual values, the measured value determined from the individual values is also corrected.Type: GrantFiled: September 13, 2012Date of Patent: January 14, 2020Assignee: Robert Bosch GmbHInventors: Bernhard Ledermann, Ulrich Belzner, Thomas Steinert

Patent number: 7584642Abstract: A procedure for the calibration of the lambda measuring signal supplied by the wideband lambda sensor, which is disposed in the exhaust gas area of an internal combustion engine, and a device to implement the procedure are proposed. During the procedure, a correction value is used to ascertain a unit of measurement for the lambda actual value, whereby the correction value is ascertained during a specified operating state of the internal combustion engine, in which no fuel metering occurs and the engine rotational speed of the internal combustion engine lies above a threshold value. The correction value—is ascertained as a function of the sensor temperature of the wideband lambda sensor during a specified operating state.Type: GrantFiled: November 20, 2006Date of Patent: September 8, 2009Assignee: Robert Bosch GmbHInventors: Andreas Michalske, Thomas Steinert
