  • Patent number: 5995896
    Abstract: A method for the control of shifting processes in a vehicle transmission from an initial gear to the next higher target gear includes the steps of continuously determining the vehicle acceleration (a) and the driven rpm (n.sub.2) behind the vehicle transmission. A shifting process is triggered when the acceleration value (a) and the essentially simultaneously recorded driven rpm value (n.sub.2) fall on a shifting point which lies on a shifting characteristic (n.sub.2 (a)) in an acceleration-driven rpm diagram, where the shifting characteristic (n.sub.2 (a)) has a stepped course with at least two break points (a.sub.-- max; a.sub.-- min) and the slope of the shifting characteristic for acceleration values a.sub.-- min<a<a.sub.-- max is always smaller than or equal to the slope of the shifting characteristic for acceleration values a.ltoreq.a.sub.-- min or a.gtoreq.a.sub.-- max. In other words, the following applies:.linevert split.n.sub.2 (a.sub.1).linevert split..ltoreq..linevert split.n.sub.2 (a.sub.
