Method for activating functions of a tachograph
First Claim
1. A method for enabling at least one function of at least one tachograph that comprises a control unit and an interface connected to the control unit, wherein the control unit is enabled by programming to perform a first group of functions, the method comprising:
- connecting an external storage medium to the interface of the at least one tachograph, wherein the external storage medium includes at least one instruction that can be read by the control unit to enable a function;
performing authentication between the external storage medium and the control unit;
enabling the function associated with the at least one instruction;
associating the function with the first group; and
breaking the connection between the external storage medium and the interface of the at least one tachograph, wherein the at least one instruction comprises another function, wherein the another function enables an available further interface of the tachograph,wherein the function can be enabled on a number of tachographs, the number of tachographs determined by a magnitude of a difference between a number stipulated by the external storage medium stored on the external storage medium and a number of enabling operations already performed by the external storage medium.

Abstract
A method for activating functions of at least one tachograph having a control unit and an interface. The control unit is activated by a program to perform a first group of functions. First, a connection of an external storage medium to the interface of the at least one tachograph is established. The storage medium has at least one instruction for activating a function, which can be read out by the control unit. An authentication between the external storage medium and the control unit also takes place. The function associated with the at least one instruction is activated in such a way that the function is associated with the first group of the control unit. Next, the connection between the external storage medium and the interface of the at least one tachograph is released.
