ABSTRACT:
A keyless entry touch pad system for a vehicle includes a substrate with a plurality of touch zones disposed on one surface of the substrate, and a plurality of electrode patterns disposed on the opposite surface. An inner electrode of each pattern is aligned with one of the touch zones. Each pattern is electrically coupled to an integrated control circuit, which outputs a signal to and energizes the electrodes of the pattern such that electric fields emanates therefrom. The electrode patterns may be capacitively coupled to the integrated control circuit. When the electric field of the inner electrode is disturbed by a stimulus proximate the corresponding touch zone, the component is activated. Upon activation of the components in a predetermined sequence, a controller causes the vehicle door to unlock. A method of unlocking a vehicle is also disclosed.
