Actuating device for a motor vehicle locking system and method for indicating the conditions of operation

摘要

The proximity or touch sensor for a road vehicle (7) locking system is mounted in a handle (6) in the door (71) and is connected (9) to an evaluation circuit (8). It has an outer conducting sensor (2) and an inner conducting sensor (3). The sensor pieces may be squeezed into contact with a conducting wire with an active haptic signal generator (5). The evaluation circuit has a connection to a radio receiver (41) tuned to a radio key or a radio frequency identity card (42).
