This part of ISO 13400 describes the general use cases and communication scenarios which are covered by an Internet Protocol-based vehicle communication standard. Each use case drives specifc communication capabilities of the vehicle communication interface, for instance in order to be interoperable in an existing computer network.
The diagnostic communication over Internet Protocol (DoIP) protocol supports the standardized service primitive interface as specifed in ISO 14229-2.
The descriptions in this part of ISO 13400 cover different application layer implementations, such as:
- enhanced vehicle diagnostics (system diagnostics beyond legislated functionality, non-emissions-related system diagnostics);
- WWH-OBD as specifed in ISO 27145-2 and ISO 27145-3.
