Method for gear selection by automatic transmission of motor vehicle, involves selecting gears within ranges, in which driver through his driving behavior does not directly influence switching strategy, based on optimum efficiency targets

摘要

The method involves selecting gears within ranges, in which a driver through his driving behavior does not directly influence the switching strategy, based on optimum efficiency targets. The gear selection is performed based on a characteristic diagram of transmission efficiency as function of gear, temperature, load and/or speed. One gear is selected during motor braking in high speed, and is again left, when high prioritized requirements are required. A long roller is identified by Global Positioning System (GPS)based on route requirements.
