- the at least one data connection parameter can include a signal strength of the transmission network. Furthermore, the at least one data connection parameter can include a signal quality of the transmission network.
- the threshold value given for a respective data connection parameter can be fixed.
- the threshold value can also be dependent on the data to be transmitted.
- the threshold value can be dependent on a data size, a data volume, a data type and / or a category of the data to be transmitted.
- a further data link parameter can be determined for another, alternative transmission network. Furthermore, the condition as to whether the further data transmission parameter is above the specified threshold value for a specified time interval can be checked.

- a wireless data connection for data transmission can be established and / or removed from the vehicle with the external unit without checking.
- the data connection can be established when data to be transmitted is present.
- the vehicle preferably sets up a data connection with the external unit. It is also useful if the vehicle starts a data transmission to the external unit when the data connection is established. If the check shows, for example, that no condition is met, it is expedient for no data connection to be established. In this way, the data to be transmitted cannot usefully be transmitted. If the test shows that no condition is met, the data to be transmitted are preferably stored within the vehicle.
- the data connection can be set up at a later point in time when at least one of the conditions is met. Then, especially when the data connection is established, the transfer of the stored data can begin / take place.
- the establishment of the data connection can depend on the result of the test of the condition.
