    摘要: The invention relates to a method for the voltage-controlled performance regulation of the heating of an exhaust-gas probe in the exhaust system of an internal combustion engine. The aim of the invention is to provide a method in which the operating temperature of the probe is achieved in the shortest possible time without damage to the probe. To achieve this, the heating voltage during the heating phase of the probe is rapidly brought up to a high temperature in a start phase in relation to a subsequent phase, or a dramatic leap in temperature is achieved, preferably up to the full operating voltage and the heating voltage is then continuously or quasi-continuously reduced.

    摘要: In a method for detecting a level of contamination of a particle sensor provided with two electrodes situated on an insulator material for generating an electrical field, the insulator material is heated to above a limiting temperature of the insulator material at which the insulator material begins to become conductive. The insulator material is modulated by heating or cooling, the modulation being carried out at a lower temperature and an upper temperature which are each above the limiting temperature. The variation over time of a measuring signal which may be picked up between electrodes is measured during the modulation. The measured variation over time of the measuring signal is compensated using a theoretical variation over time of the measuring signal in a contamination-free state of the particle sensor in order to obtain a variation over time of a differential signal.
