The invention relates to a device for operating electrical or electromechanical devices ( 10 ) in a vehicle, whereby a sensor ( 40 ) is used, operating on proximity or contact. According to the invention, the device can distinguish whether operation of the sensor ( 40 ) is actually carried out by a human hand, or by erroneous objects, whereby, in an initial adjustment phase, the device records at least one set of data for each signal and stores the same in a memory, which occur at at least some defined timepoints during the signal time course of the corresponding sensor ( 40 ). A set of operationally-typical valid data and/or a set of error-typical invalid data is thus obtained. During the subsequent operational phase for the device, an actual data set of analogue signals for the corresponding sensor ( 40 ) is recorded during the time course at the same defined timepoints as for the adjustment phase. Said actual data set is compared by a controller with at least one of the stored data sets. Operation of the device ( 10 ) is thus only permitted by the controller ( 44 ), when the actual data set matches the valid data set and/or is not contained within the invalid data set. |
