Verfahren und Vorrichtung zur Steuerung einer Getriebegruppe eines Kraftfahrzeuges

摘要

For a transmission group (2) comprising a gearbox (10) and an actuating group (24) coupled to the gearbox (10) for commanding engagement/disengagement of the gears, the method comprises the steps of generating at least one command signal (GEAR1, GEAR2) for the actuating group (24) having, during a first operating step of a gear change manoeuvre, a width the time pattern of which comprises at least one first section wherein the width of the command signal (GEAR1, GEAR2) increases in substantially linear fashion according to an increase coefficient ( mu ) from an initial value (IO) to an intermediate value (ILIM); and of calculating the increase coefficient ( mu ) and the initial and intermediate values (IO, ILIM) in relation to at least one first operative reference value representing the shift of gear to be effected during the gear change manoeuvre and a correction value (W) representing the style of driving the vehicle.
