<p>The invention relates to a method for controlling a dual-clutch gearbox of an automobile, characterised in that said method comprises the following steps: defining a currently engaged gear ratio (R1) and a desired final gear ratio (RF), the gear ratios being distributed in two halves of the gearbox, a first half of the gearbox comprising even-numbered gear ratios and a second half of the gearbox comprising odd-numbered gear ratios. Each gear ratio comprises a first pinion, solidly connected to one of two gearbox input shafts, said first pinion being meshed by a second pinion freely mounted on a secondary shaft and solidly connected by means of a synchroniser; a variation of the speed of the input shaft biased for synchronisation of the final ratio (RF) is defined; when the speed of the input shaft increases, one or more synchronisers of ratios higher than the desired final gear ratio (RF) of the half gearbox are sequentially biased in decreasing order, after shifting the engaged gear ratio (R1), and when the speed of the input shaft drops, one or more synchronisers of ratios lower than the desired final gear ratio (RF) of the half gearbox are sequentially biased in rising order, after shifting the engaged gear ratio (R1).</p> |
