Optimizing shift strategies through driving simulation
First Claim
1. A method for optimizing the shifting of transmission gears (gear ratios) in a motor vehicle for a given route along which the motor vehicle is being driven, comprising:
- conducting a plurality of simulations of driving the motor vehicle along the given route for a period of time extending into the future, wherein a different, non-previously-assigned or non-previously-fixed gear-shifting strategy comprising one or more combinations of engine speed and from/to gear-shift sequence according to which the motor vehicle potentially could be operated while being driven along the given route for the period of time extending into the future is tested or gamed out in each of the simulations;
selecting from among the various gear-shifting strategies that have been tested or gamed out one which is specifically tailored to the given route to optimize a preselected driving-related criterion; and
implementing the selected gear-shifting strategy while the motor vehicle is being driven along the given route.

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.
