ABSTRACT:
The invention is related to capacitive sensing and detection systems and methods. In one embodiment, a capacitive sensor system comprises a first electrode and a second electrode forming a first capacitive sensor mounted to a vehicle and configured to create a first electric field directed outward from the vehicle, and a control unit coupled to the first and second electrodes and configured to measure a change in the first electric field. In another embodiment, a method comprises capacitively sensing an object relative to a vehicle and communicating information related to the object. In yet another embodiment, a method comprises configuring a capacitive sensor to sense an object relative to a vehicle, and providing a path to communicate information from the capacitive sensor.
