Abstract: For connecting a diagnostic unit to a vehicle controller of a motor vehicle via a network connection, it is provided that, when the connection has been established between the diagnostic unit and the vehicle controller, a check is performed as to whether the diagnostic unit is directly connected to the vehicle controller. The diagnostic unit receives diagnostic data from the vehicle controller only when there is a direct connection.

Abstract: A method establishes a wireless communication connection between a vehicle communication unit of a vehicle and a charging station communication unit of a charging station. The method includes the transmission of a low-frequency signal via a LF transmission unit of the vehicle, wherein the LF request signal displays an identifier relating to the vehicle. The method also includes the receiving of the LF request signal via an LF receiving unit of the charging station. The method further includes the transmission of information relating to the identifier in a broadcast message via the charging station communication unit, as well as the receiving of the broadcast message via the vehicle communication unit. In addition, the method includes the checking of whether the broadcast message comprises the information relating to the identifier, and the establishing of a wireless communication connection between the vehicle communication unit and the charging station communication unit, if the broadcast message comprises the information relating to the identifier.

Abstract: A method for validating a time function in a network of a vehicle includes: ascertaining a receiving time of a sync message of a master; receiving a follow-up message of the master; ascertaining a receiving time of a further sync message of the master; receiving a further follow-up message of the master; determining a time function of the first client based on the receiving time of the sync message, the receiving time of the further sync message, the transmission time of the follow-up message, and the transmission time of the further follow-up message; ascertaining a synchronized transmission time of a path delay request message from the first client to the master; ascertaining a synchronized receiving time of a path delay response message from the master; receiving a path delay response follow-up message from the master by the first client; and validating a time function of the master.
