1 Scope
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 specific 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 specified
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 specified in ISO 27145‑2 and ISO 27145‑3.
