Abstract
Sensor adaptable del ángulo de dirección absoluto para la determinación absoluta de un ángulo de giro, especialmente para la determinación del ángulo de la dirección en un automóvil por medio de un código (2) aplicado sobre una región angular de 360º para la determinación del ángulo, donde el código (2) y una disposición de detector (7) están dispuestos de forma giratoria entre sí, donde se realiza una determinación absoluta del ángulo a través de la lectura de la información de contraste por medio de un microprocesador (8), que determina tanto la posición angular del código como también la resolución fina del ángulo a través de la posición relativa del código reconocido para la reproducción sobre la disposición de fotodetector y donde al mismo tiempo, con cada medición, se verifica y se adapta la función total del sistema, caracterizado porque el código se determina por medio de una disposición de fotodetector colocada en un único lugar y se utiliza para la determinación del ángulo, porqueun segmento contiguo de la pista del código se reproduce sobre al menos una línea de fotodetectores (7), donde al menos se detecta una palabra de código, a la que corresponde un ángulo predeterminado, porque se mide la posición de la palabra de código con respecto a la posición fija de la línea de fotodetectores (7), porque el código es reproducido a través de una óptica (6) sobre la línea de fotodetectores (7) de tal manera que con un ciclo de lectura de la matriz lineal tanto se determina la información absoluta del ángulo como también se verifica y se adapta la función total del sistema, y porque para la supervisión de las funciones del sistema se proyecta al menos una imagen de sombra de referencias sobre la matriz lineal de fotodetectores (7).
