    摘要: A method of determining the size of a gear interval from a currently engaged gear to a target gear in a transmission. The method includes the steps of, for each current gear and for each possible gear interval from the current gear, recording a limit value for an acceleration or a deceleration in the target gear corresponding to the current gear and the respective gear interval used; for the current gear, starting with the smallest gear interval, applying a loop with successive increases of the gear interval to determine, depending on the current driving situation and characteristic parameters of the vehicle, the acceleration or the acceleration theoretically obtainable in the target gear produced by using the gear interval, which is compared with the respective recorded limit value until the acceleration or the deceleration theoretically obtainable no longer contravenes the limit value. The gear interval is then selected for a gearshift.
