Method and control unit for communicating with a vehicle

A computer program product comprising computer program code stored on a non-transitory computer-readable medium, said computer program product used for communicating with a vehicle, said vehicle comprising:

• at least one vehicle internal system;
• at least one add-on system, said add-on system being arranged in said vehicle after said vehicle is produced by a manufacturer;
• and at least one internal communication unit configured for communication with at least one vehicle external communication unit, said computer program code comprising computer instructions to cause one or more control units to perform the following operations:
• configuring an add-on interface, the add-on interface being arranged in said vehicle as an interface between the at least one vehicle internal system and the at least one add-on system, by defining:
• at least one function of said add-on interface, and at least a signaling format to be used by said at least one internal communication unit for said communication with said at least one vehicle external communication unit;
• creating an immutable and unique identifier ID related to the configuration of the add-on interface;
• and
• communicating, using said at least one internal communication unit and said immutable and unique identifier ID, with said at least one vehicle external communication unit.

A control unit arranged with a vehicle, said vehicle comprising:

• at least one vehicle internal system;
• at least one add-on system, said add-on system being arranged in said vehicle after said vehicle is produced by a manufacturer;
• and at least one internal communication unit configured for communication with at least one vehicle external communication unit;
• said control unit configured for:
• configuring an add-on interface, the add-on interface being arranged in said vehicle as an interface between the at least one vehicle internal system and the at least one add-on system, by defining:
• at least one function of said add-on interface;
• and at least a signaling format to be used by said at least one internal communication unit for said communication with said at least one vehicle external communication unit;
• creating, an immutable and unique identifier ID related to the configuration of the add-on interface;
• and
• communicating, using said at least one internal communication unit and said immutable and unique identifier ID, with said at least one vehicle external communication unit.
