Method for evaluating the state of a soot sensor in a motor vehicle |
摘要 |
A method for performing on-board functional diagnostics on a soot sensor of a vehicle and/or for detecting further components in the soot in a motor vehicle having an internal combustion engine. The soot sensor is electrically connected to an evaluation circuit with is permanently installed in the motor vehicle. In order to specify a method for performing functional diagnostics on a soot sensor and/or for detecting further components in the soot, with which method it is possible to detect a faulty soot sensor and/or further components in the soot in a cost-effective way, the evaluation circuit measures the temperature coefficient of the soot sensor and detects the defectiveness of the soot sensor and/or the presence of further components in the soot on the basis of the temperature coefficient of the soot sensor. |
