Abstract (en)
[origin: WO02064996A1] Drive unit for motor vehicles, comprising an internal combustion engine (1) and a gearbox (9) connected to the engine via an automated clutch (3), said gearbox (9) consisting of a non-synchronized stepped main group and thereafter a two-range synchronized range group with a free position between its range positions. The clutch and the gearbox are controlled by an electronic control unit (45), to which there are fed signals representing the selected gear from a gear selector (46) and signals representing various engine and vehicle data. The control unit is disposed, when the vehicle is standing still and the gear selector in the free position, to keep the clutch engaged and the range group in the free position. When a gear is selected, the clutch is first disengaged, whereafter the range group is moved to one of the engaged positions to brake the intermediate shaft and make possible engagement of the gear in the main group. After engagement in the main group, the clutch is engaged.
