Abstract

Motor-driven cargo vehicle with an automated clutch (33) and gearbox (39) between the engine (31) and the vehicle drive wheels. The gearbox and the clutch are controlled by an electronic control unit (19) depending on a set position of a manual gear selector (53). The control unit is arranged, when starting off with the gear selector in the position for automatic shifting, to select the highest gear speed which makes starting off of the vehicle possible with the available torque at engine idle speed, introducing an amount of energy from the engine to the clutch which at most amounts to a predetermined maximum value.
