Vehicle skid plate sensor system and methods of use
A vehicle assembly includes, among other things, a bumper assembly, a skid plate, and a capacitive sensor system of the skid plate. A sensing method for a vehicle includes using a capacitive sensing system to detect a proximity of a vehicle to an object. The capacitive sensing system is incorporated into a skid plate that is vertically beneath a portion of a bumper assembly of the vehicle.
