Abstract

Procedimiento para controlar un sistema de transmisión mecánica de cambio de engranajes semiautomática (10) comprendiendo un motor controlado por acelerador y combustible (14) provisto de una velocidad libre conocida (ESIDLE), una transmisión mecánica de cambio de engranajes de múltiples velocidades (12), un embrague maestro de fricción (16) interpuesto entre el motor y la transmisión, una palanca de selección del cambio accionada manualmente (1) desplazable en una primera dirección desde una posición centrada para seleccionar cambios hacia arriba y en una segunda dirección desde dicha posición centrada para seleccionar cambios hacia abajo desde la relación de transmisión actualmente acoplada, una unidad central de proceso (38) para recibir entradas indicativas de la relación de transmisión acoplada de la velocidad del motor (ES), de la velocidad del árbol de salida de la transmisión (OS) y del funcionamiento de dicha palanca manual de selección del cambio y para procesar las mismas de acuerdo con reglas lógicas predeterminadas para emitir señales de salida de mandato a los accionamientos no controlados manualmente incluyendo un accionamiento del embrague (30), un accionamiento del control del acelerador y combustible (26) y un accionamiento de la transmisión (34), dicho procedimiento caracterizado porque si dicha transmisión está en neutro (GR=N) y dicha velocidad del vehículo excede de un valor de referencia mínimo (OS>REF), automáticamente selecciona el funcionamiento en un modo de funcionamiento de arranque de la rodadura, en el que un único movimiento de dicha palanca de selección del cambio en la dirección de cambio hacia arriba es interpretado como una selección del operario de un cambio directo desde neutro a una relación de transmisión adecuada de arranque de la rodadura (GRRS), dicha relación de transmisión apropiada de arranque de la rodadura determinada como una función de la velocidad actual del vehículo y del gradiente de la misma.
