Abstract

A method for detection of a control event by a sensor arrangement having at least one sensor element and a sensor controller is described. The sensor controller digitizes sensor signals into sensor measured values. An operator control event is produced by a user and a first coarse evaluation for a sign of operator control is performed and a predetermined number of sensor measured values are progressively buffer-stored in a buffer store wherein detection of a sign of operator control initiates a fine evaluation of the sensor measured values to verify the occurrence of an operator control event at an initiation time. The fine evaluation is based on the buffer-stored sensor measured values and on subsequent sensor measured values, so that the fine evaluation includes sensor measured values both before and after the initiation time.
