Vehicle assembly having a capacitive sensor
An illustrative assembly includes a panel and a capacitive sensor. The panel is movable between an opened position and a closed position relative to a closure of a vehicle body. The sensor is positioned on the panel such that at least a portion of the sensor is perpendicular to the closure of the vehicle body as the panel moves between the opened and closed positions. The sensor capacitively couples to an electrically conductive object proximal to the closure of the vehicle body such that capacitance of the sensor changes.
