Abstract
A method is disclosed for automatically shifting the subtransmission of a vehicle which is also equipped with a manual transmission operated by hand by the driver. When the driver shifts by hand to a certain gearing ratio, a vehicle operating parameter is detected, and, on the basis of this detected value, the procedure for shifting the sub-transmission is modified. Shift control of the sub-transmission is then performed in accordance with this modified sub-transmission shift procedure, while the manual transmission remains in this gearing ratio.
