Method for operating automatic transmission in motor car, involves displacing shifting up points temporarily toward higher running speed as function of acceleration of motor car if acceleration of car exceeds acceleration threshold value

摘要

The method involves determining shifting up points between gears by using coordinate values in a map, where a parameter assigned by running speed of dependent parameters over a drive torque of a prime mover or vice versa is applied in the map. The shifting up points are displaced at a slope portion in relation to a basic program such that the motor car is traveled in a plane. The shifting up points are displaced as a function of an acceleration of the motor car temporarily towards higher running speed if the acceleration (a) of the motor car exceeds an acceleration threshold value (a1).
