Abstract
The invention relates to a method for accelerating a vehicle with a continuously variable transmission () where a gear ratio of the transmission is at first larger than a gear ratio of a virtual fixed gear. While the vehicle is accelerating, the gear ratio of the transmission is increased to the gear ratio of the virtual fixed gear. The transmission is then operated with the gear ratio of the virtual fixed gear.
