Resumen
The present invention relates to an electronic system based on a microcontroller for the electrical connection of trailers, semi-trailers or caravans to vehicles, more specifically for powering the various light-signalling electric circuits, being automatically adapted to the electrical characteristics of the actual vehicle. The object of the invention is to provide a system that allows the connection of trailers to vehicles in a manner compatible with self-checking systems, which systems increasing numbers of vehicles incorporate, including those that are different from one another and that do not function correctly when a trailer equipped with light signalling is coupled to said vehicles. Furthermore, it also makes it possible to inhibit the parking sensor of vehicles that incorporate such a sensor when said trailer is connected to the vehicle, with a view to eliminating false proximity alarms.
