Abstract
The invention relates to a communication circuit which is used to connect, via a data bus, window-opening and -closing switches to the control circuits for the respective motors thereof and to the central vehicle controller. Said system can be used to control the sun roof and the passenger window from the driver's seat. The aforementioned switches can be: rotated, in order manually to adjust the degree that the window is opened; and moved, in order to activate the automatic and full opening or closing of the window.
Claims12
An advanced automobile window-opening operation device consisting of an electromechanical set that includes an activation switch and electronic switching circuitry that can operate on an electrical motor mechanically associated to the vehicle's window-opening mechanism (6), characterized because the mentioned switch operates on the window opening mechanism (6) by means of the aforementioned electronic switching circuitry, which includes a switching board (3) (“Door Switch Node”), provided with communication through a multi-signal channel (4) or bus to the electronic system of the vehicle and connected through another multi-signal channel or bus to the activation and control board (2) (“Smart Power Windows Motor”) of the electric motor (1) of the window-opening device (6), being these circuits connected to the vehicle's chassis (5).
