Germany has filed an application for a new standardization project (NWIP): ”Road vehicles – Application profile for CAN-based network – Framework for special-purpose cars”.
This application profile specifies the CAN physical layer as well as application configuration and diagnostic parameters for the add-on devices used in special-purpose passenger cars such as taximeter, roof bar, etc. This document (also known as CiA447) specifies the physical layer, the data link layer and related communication services, the general system architecture and power management.
We believe that the creation of a new international standard would lead to further adoption and benefits for vehicle manufacturers and customizers. If there is sufficient interest we understand this project will be developed within the ISO working group TC22 SC31 WG3 “Road vehicles – Data communication – In-vehicle networks”.
If you would like to see this happen please contact Sarah Follert at CAN-in-Automation for details on who to contact in your country. Her email address is at the end of this article regarding the push for international standardization for car add-on devices.
