Abstract

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.
