STANDARDIZATION IN THE AUTOMOTIVE INDUSTRY

摘要

More than 25 years ago, Robert Bosch laid out the Controller Area Network (CAN) concept for the needs and requirements of the automotive industry. CAN is now extensively used in the automotive industry and every major international carmaker has adopted it for most of their product lines - almost every new car uses CAN. However, there is no standardized higher layer protocol in use so far. There are several attempts in standardization like OSEK (Offene Systeme und deren Schnittstellen fur die Elektronik in Kraftfahrzeugen; or in English: Open Systems and their Interfaces for the Electronics in Motor Vehicles), but they are not very widely adopted. Now, together with different carmakers, CAN in Automation (CiA) has developed one defined interface based on the international standardized higher layer protocol CANopen.
