Abstract
Sistema de control electrónico para vehículos con un sistema de propulsión de desplazamiento principal para determinadas ruedas de rodadura y un sistema de propulsión auxiliar para otras determinadas ruedas de rodadura, especialmente para vehículos con dos partes de vehículo unidas articuladamente entre si y asociadas en cada caso sólo con el sistema de propulsión principal o con el sistema de propulsión auxiliar, que consta de un circuito de entrada para una señal de entrada previamente establecida, un circuito perceptor para la generación de una señal de valor real, un circuito comparador para comparar ambas señales y para generar una señal de control con el fin de controlar el estado de funcionamiento del sistema de propulsión auxiliar, caracterizado porque el circuito de entrada tiene un perceptor para percibir la velocidad del sistema de propulsión principal o de las ruedas de rodadura propulsadas por éste, porque detrás del circuito de entrada está conectado un primer circuito de modificación que modifica la señal de entrada en un porcentaje previamente determinado del valor de velocidad, porque el circuito perceptor tiene un perceptor para percibir la velocidad del sistema de propulsión auxiliar, y porque en función de la señal de control y la señal de retroalimentación proporcional al valor real de la velocidad del sistema de propulsión auxiliar, el sistema de propulsión auxiliar es propulsado siempre on una velocidad diferente en un primer porcentaje previamente determinado con respecto al sistema de propulsión principal.
