Abstract: A method for documenting an update of software of a component of a vehicle includes receiving in a backend a request message transmitted by the vehicle, the request message comprising system parameters of the vehicle. In response to the request message, a check is carried out at the backend using the system parameters in order to determine whether an update of the software of the component is required and, if so, transmitting an update message by the backend to the vehicle. The update message includes at least one text module which in each case describes a change relating to existing software of the component. A respective text module is assigned in each case to a component. In response to the update message, the at least one text module is provided on an output unit assigned to the vehicle.
