Method for qualifying sensor measuring signal of sensor in exhaust gas system of internal combustion engine of motor vehicle, involves detecting sensor measuring signal and applying plausibility check on sensor measurement signal

摘要

The method (100) involves detecting a sensor measuring signal and applying a plausibility check on the sensor measurement signal. The plausibility check takes place in a period of time, which lies between an ignition-switching time of an ignition of an internal combustion engine and a sensor activating time. The result of the plausibility check influences a subsequent signal processing process of the sensor measuring signal. Independent claims are included for the following: (1) a device for qualifying a sensor measuring signal of a sensor in an exhaust gas system of an internal combustion engine of a motor vehicle; and (2) a motor vehicle with a controlling- or regulating unit.
