Abstract

La invención se refiere a un sistema para impulsar un elemento de ajuste (114, 116 y 118) en un vehículo motorizado con señal modulada con ancho de impulso (suPWM). Para impedir un enclavamiento de la señal (uPWM) después de una secuencia de tiempo opcional cuando menos entre dos frecuencias (f1 y f2), que provocan en el elemento de ajuste (114, 116 y 118) oscilaciones de diferente amplitud. Tanto la secuencia del cambio como también las frecuencias (f1, f2) pueden seleccionarse ó en forma libre, ó combustión (100). Al fin de evitar dentro de lo posible una afectación molesta de las señales del censor a raíz del elemento de ajuste en oscilación, se pueden tomar las siguientes medidas: Sobre la frecuencia (f2) que provoca en el elemento del ajuste (114, 116 y 118) las oscilaciones mas fuertes, solamente se cambia en las zonas operativas insensibles, ó bien se afectan las señales del censor durante la operación del elemento de ajuste (114, 11 y 118) en forma adicional y dirigida con esta frecuencia (f2).The invention relates to a system for driving an adjusting element (114, 116 and 118) in a motor vehicle with pulse width modulated signal (suPWM). To prevent a signal interlock (uPWM) after an optional time sequence between at least two frequencies (f1 and f2), which cause oscillations of different amplitudes in the adjustment element (114, 116 and 118). Both the sequence of change and also the frequencies (f1, f2) can be selected either freely, or combustion (100). In order to avoid as far as possible annoying affectation of the sensor signals due to the oscillating adjustment element, the following measures can be taken: On the frequency (f2) that it causes in the adjustment element (114, 116 and 118) the strongest oscillations are only changed in the insensitive operating zones, or the sensor signals are affected during the operation of the adjustment element (114, 11 and 118) in addition and directed with this frequency (f2).
