    摘要： The invention relates to a device for operating a particle sensor in the exhaust gas duct of an internal combustion engine, the particle sensor comprising an interdigital electrode for determining the particles contained in the exhaust gas and a heater for regenerating said particle sensor and an engine management system being associated with the internal combustion engine. Provision is thereby made for a probe control unit to be connected to said particle sensor, for the probe control unit to be disposed in a separate assembly between said particle sensor and the engine management system and for said probe control unit to be connected to said engine management system via a digital bus or an analog interface. The invention relates further to a corresponding method. Device and method allow for the autonomous operation of a particle sensor without the engine management system having to be configured for the operation of said particle sensor.

    摘要： A method is described for diagnosing an exhaust gas sensor which is situated in the exhaust gas area of an internal combustion engine for the purpose of detecting at least one exhaust gas component, which is heated with the aid of a sensor heater and whose temperature is detected. A device for carrying out the method is also described. The exhaust gas sensor is heated to a diagnosis starting temperature which is higher than the exhaust gas temperature; the heat output of the sensor heater is reduced or the sensor heater is completely turned off at least to the extent that the sensor temperature is able to decrease; the decreasing sensor temperature is detected; a measure for the temperature drop in relation to time is ascertained; this measure is compared with a first temperature gradient threshold value; and an error signal is provided if the temperature drop is too slow and therefore the ascertained measure for the temperature drop in relation to time does not exceed the first temperature gradient threshold value.

    摘要： In a method for determining the reset time in a pressure sensor that detects the pressure in a combustion chamber of an internal combustion engine and emits a corresponding pressure signal, with the pressure curve in the combustion chamber having at least one high-pressure region the reset time is determined as a function of at least one pressure value detected in the high-pressure phase, so that it is possible, within the sensor, to determine a favorable time at which to reset the drift, based on the pressure range In the method according to the invention, information about the auxiliary rotation speed is determined based on the pressure curve of the compression phase and is then used to generate the reset time, the method entails only slight circuitry-related expense and can therefore be implemented even in an ASIC without complex signal processing, and it functions in almost all known engine operating states.
