Abstract:
A sensor-controlled key system for a motor vehicle for releasing an access authorization and for actuating auxiliary functions includes a control device having an electronic key device. The key system further includes at least one optical sensor device with at least one optical sensor element. The optical sensor element has a beam path that defines at least two observation regions B1, B2, Bn. The control device has a switching function that switches observation regions B1, B2, Bn on and off in dependence on a verified or non-verified access authorization.
