1. A method for operating an automatic transmission (3) comprising the steps of:
- generating a command automatically or by manual input in a manual shifting mode, to change a current ratio of the automatic transmission (3) when achieving a preset operating state of the vehicle, an activated shifting mode being preferred to the manual shifting mode; and
ending the manual shifting mode when a current vehicle speed is less than a threshold value and ending the manual shifting mode when at least one of the three following criteria are met;
a longitudinal acceleration of the vehicle is within a defined range;
a lateral acceleration of the vehicle is less than the threshold value; and
a driver type evaluation counter is less than a limiting value.

Abstract
A method is described for operating an automatic transmission in which a command for changing a current ratio of the automatic transmission is generated when achieving preset operating states of the vehicle automatically or by manual input in a manual shifting mode, the activated manual shifting mode being preferred to an automatic shifting mode. The manual shifting mode is quit when a current vehicle speed is less than a threshold value, or when a longitudinal acceleration of the vehicle is within a defined range, a lateral acceleration is less than a threshold value and a driver type evaluation counter is less than a limiting value.

14. A method for operating an automatic transmission (3) comprising the steps of:
-
generating a command automatically or by manual input in a manual shifting mode, to change a current ratio of the automatic transmission (3) when achieving a preset operating state of the vehicle, the activated shifting mode being preferred to the manual shifting mode; and encing the manual shifting mode when a current vehicle speed is less than a threshold value or when the three following criteria are met; a longitudinal acceleration of the vehicle is within a defined range; a lateral acceleration of the vehicle is less than the threshold value; and a driver type evaluation counter is less than a limiting value, and activating a shift program coordinated with the actual driver type evaluation counter during a change to the automatic shifting mode. - View Dependent Claims (15, 16, 17, 18, 19, 20)
