Automatic circuit with theft prevention and control methods

With the present invention a method for controlling an automatic gear change of a vehicle, a control apparatus in which such a process runs as well as a vehicle having such a control device is claimed. It is provided that an efficient mode is provided for controlling the automatic transmission, wherein the gear shift or translation of the gear shift is chosen such depending on the environment and / or operating parameters that an energy-optimal in the essential propulsion of the vehicle is made possible. It is immaterial whether the time spent on the driving power from a motor and / or a mechanically applied force, such as the stepping force of a bicyclist comes. The essence of the invention consists in the fact that the control of the gear shift in response to a safety signal which represents the securing the vehicle against unauthorized movement or theft, further performs the further operation of the gear change takes place in the efficient mode in an inefficient mode.
