Abstract
A motor vehicle includes a clutch and an automated transmission between the engine and the drive wheels of the vehicle. A method for shift control in the motor vehicle when starting off or under way includes continuously performing computer simulations of the future driving of the vehicle, at least in response to information on road incline and throttle opening position, for a set of different shift schedules with combinations of engine speeds when shifting and shift steps, and selecting a shift schedule from the set of shift schedules which is optimal with regard to a selected criterion.
