Abstract

In the case of a process for changing an electronic memory for use-related data of a vehicle, the changed new data and the old data maintained in the memory are sent to a comparator, in which case the comparator permits the taking-over or acceptance of the new data into the memory only if the new data have changed in comparison to the old data in a manner which conforms with the use of the data.
