Abstract
A particle sensor arranged in an exhaust duct such that particles from the exhaust-gas flow accumulate on and/or between at least two sensor electrodes when a voltage greater than a limit voltage is applied between the two sensor electrodes and substantially no particles accumulate if the voltage is lower than the limit voltage. During a first time period, a first voltage greater than the limit voltage is applied between the sensor electrodes. During a second time period, a second voltage, lower than the limit voltage, is applied between the sensor electrodes, and/or the particle sensor is heated to a predefined temperature, such that substantially no particles accumulate on and/or between the at least two sensor electrodes. Following the second time period, a third voltage greater than the limit voltage is applied between the sensor electrodes.
