CiA 602-2 version 1.1.0CAN FD for commercial vehicles – Part 2: Application layer
DescriptionThis series of documents specifies the in-vehicle communication between ECUs (electronic control units) for commercial vehicles based on the CAN FD data link layer as defined in ISO 11898-1. Commercial vehicles include trucks, heavy-duty trucks, buses as well as off-road and off-highway vehicles. The CAN FD for commercial vehicles specification series consists of the following parts: Part 1: Physical layer, Part 2: Application layer. This part specifies the application layer protocols based on the SAE J1939 surface vehicle recommended practice series. It includes Autosar compliant protocol data units, which comprises parameter groups as specified in SAE J1939-21 and SAE J1939-71 as well as an optional safety/security field.
