Motor vehicle having an automated transmission
First Claim
1. A motor vehicle with a clutch (3) and automated transmission (9) between the engine and the drive wheels of the vehicle, comprising control means (45,48) for controlling the engine and for controlling the transmission in accordance with a selected position for an electronic gear selector (46), where the control means, with the gear selector in its position for automatic shifting, upon movement, selects a gear which is determined by a gear setting preference, stored in the control means, as a function of various driving preference parameters fed into the control means, the control means comprising:
- a first simulation of an intended path of the vehicle in response to measured and sensed information (360, 330, 320, 350) for a set of different shift schedules, and select an optimal shift schedule from said set of shift schedules with regards to a first set of weighted driving preference parameters (U1) derived from a weight assigned to each driving preference of the set of the various driving preferences,a second simulation of the intended path of the vehicle in response to said measured and sensed information (360, 330, 320, 350) for a set of different shift schedules and select a shift schedule from said set of shift schedules which is optimal with regard to at least one alternative set of weighted driving preference parameters (U2-UN) and,a comparative analysis of results (R1-RN) of the first simulation and the second simulation in order to identify the optimal set of the weighted driving preference parameters and an optimal selected shift schedule.

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).
