Patent ID: 8200402

Claim:
A method of carrying out a shift of gears of an automatic transmission of a motor vehicle when driving either with or without utilization of a clutch, the vehicle having a drive train with a drive motor, the automatic transmission having several fixed transmission ratios, an automatic shifting clutch being arranged between the drive motor and the automatic transmission, and a shift control device for controlling a change in a transmission ratio of the automatic transmission according to at least one of a driver input and an automatic gear selector device which performs the change in the transmission ratio of the automatic transmission, after a decision by a decision device, either with or without disengaging the clutch, the method comprising the steps of: disengaging a starting gear, with the decision device, in the presence of certain basic conditions without disengaging the clutch; reading data into the decision device about a size and a progression of a measure which closely correlates with a rotational speed of an output shaft of the automatic transmission; and determining, via the decision device, a shifting mode for engaging a target gear, either with or without disengaging the clutch, which depends at least on the data read into the decision device.
