Abstract
A device and a method for storing and/or analyzing data in a memory in a motor vehicle is described, the data being transmitted in the vehicle over a data bus to which are or can be connected components such as vehicle systems, sensors, actuators and other vehicle components. The memory is designed as a central memory medium for the components connected to the data bus, and it is also connected to the data bus in the vehicle. The data is stored permanently in the memory medium for the entire service life of the vehicle. In addition, the data is interpreted by analyzing arrangements connectable to the memory medium, preferably in such a manner that a measure of the usage and/or wear of the vehicle and/or its components is obtained.
