Abstract:
A keyless entry system for an automobile includes a capacitive touch screen having at least one drive line and at least one sense line, the drive and sense lines defining a plurality of touch detection nodes. The touch screen is associated with an exterior surface of the automobile. A control circuit coupled to the touch screen is configured to detect proximity of a stimulus to the touch detection nodes. The control circuit provides a control output to a lock or latch controller when the control circuit determines that the stimulus has been placed proximate the touch detection nodes according to predetermined criteria.
