Abstract

According to the invention, vehicular electronic equipment provides an antenna located in the lower portion of the window. Electronic and mechanical accessories of the vehicle are controlled by a control unit which is controlled or actuated in accordance with information received through the antenna. One end of the antenna is formed for an interface contact. The control unit and the antenna are coupled via interface contacts. Preferably the coupling is so controlled that the two contacts thereof are kept open while the window is moving, and in a closed position when the window is stationary. The control unit analyzes whether all doors are locked and the results of such analysis is outputted to the outside of the vehicle through the antenna. This assists in preventing theft.
