Method for operating an automatic gearbox on a motor vehicle
First Claim
1. Method for operating an automatic transmission (3) in which a command to change a current ratio of said automatic transmission (3) when achieving a preset operating state of the vehicle is generated automatically or by manual input in a manual shifting mode, the activated shifting mode being preferred to an automatic shifting mode and the manual shifting mode being quit when a current vehicle speed is less than a threshold value or alternatively the three following criteria are met:
- a longitudinal acceleration of the vehicle is within a defined range and a lateral acceleration of the vehicle is less than a 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.
