A sensor array for the detection of movement gestures on a motor vehicle includes two elongated sensor electrode arrays offset from each other on the motor vehicle. At least one control and evaluation device is coupled to the arrays and detects a change in their capacitance. A longer array is deformed in the direction of a shorter array where the longer array protrudes over the shorter array. The control and evaluation device is designed to detect a time sequence of capacitance values for each of the arrays. The times when each array responds and stops responding are recorded, as is the time difference between the times when the arrays respond (response time difference), and the time difference between the times when the arrays stop responding (drop-out time difference). These are compared when assessing whether an actuation event has been recorded by the control and evaluation device. |
