Abstract
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 control elements (45,48) for engine function and transmission function depending on a set position of an electronic gear selector (46). The control elements, with the gear selector in its position for automatic shifting, selects a gear for starting off or under way, which is determined by the gear selection strategy stored in the control means as a function of various parameters fed into the control elements. The control elements, are arranged to perform, firstly, a simulation process related to the gear selection strategy with at least one alternative set of parameters (U2-UN) and, secondly; a comparative analysis based on a first set of control parameters (U1).
