<p>The present invention relates to a motor vehicle with a clutch (3) and an automated transmission (9) between the engine and the drive wheels of the vehicle. The vehicle has a first electronic control unit (48) for controlling the engine, a second electronic control unit (45) for controlling the transmission, depending on a set position of a manual gear selector (46). The second control unit, with the gear selector in position for automatic shifting, selects a gear for starting off or under way, which is determined by the gear selection strategy stored in the second control unit as a function of various parameters fed into the second control unit. The invention is characterized in that the second control unit is disposed, at starting off or under way, to continuously perform computer simulations, at least on the basis of information on road incline and throttle opening position, of the future travel of the vehicle, for a set of different combinations of shift rpm:s and shift increments. This is in accordance with a criterion selected automatically or manually by the driver, using a switch. The second control unit selects out a shifting schedule which will be optimal in accordance with the selected criterion.</p> |
