  • Process for controlling an automatic gearbox
    Patent number: 5748472
    Abstract: A process is proposed for controlling an automatic transmission (3), in which at least one of the weighted values: selector lever activity, excess engine torque, curve radius and brake activity determines a first parameter (K1), the driving activity. Besides the first parameter (K1), a second parameter (K2) determines the selection of a shift characteristic field (31) among a plurality of shift characteristic fields. The second parameter (K2) is determined according to a driving state: city traffic (27), trailering (28) and mountain driving (29).
