A method for transmitting one or more data elements from a vehicle to a server via a communication channel between the vehicle and the server includes the vehicle determining a first event, and transmitting the first event from the vehicle to the server via the communication channel. The server receives the first event and determines a relevance parameter of the first event. Responsive to the relevance parameter indicating that the first event is relevant to the server, a message is transmitted requesting a first data element associated with the first event from the server to the vehicle via the communication channel. The vehicle receives the message for requesting the first data element and determines the first data element associated with the first event. The first data element is transmitted from the vehicle to the server via the communication channel on the basis of a communication-channel-specific parameter of the communication channel.

A method determines a quality characteristic, in which the quality characteristic is representative for the procurement of a vehicle-specific friction coefficient of a vehicle and a standardized friction coefficient of a friction coefficient map. The friction coefficient data are received, the friction coefficient data being representative for a friction coefficient measured depending upon the position of a vehicle and a quality characteristic representative for the vehicle. The friction coefficient map is provided, the friction coefficient being representative for standardized friction coefficients of a vehicle fleet of a route network. Depending upon the friction coefficient data and the friction coefficient map, the quality characteristic is determined again and transmitted to the vehicle.
