3. CAN-FD specifications
3.1 General
After 30 years of use in the automotive and industrial sectors, the CAN bus needed to evolve its characteristics: now it has, with CAN-FD (CAN flexible data rate). This technological evolution should extend the life of the CAN bus.
Without this development, it's likely that other buses would have replaced it in the automotive sector within a few years at least. Other communication buses have already entered the fray, but as deployment is not as straightforward, CAN-FD enables a smooth transition.
Today's automobiles are equipped with a host of communicating electronic devices (on-board systems). This equipment is multiplying as automakers focus on improving comfort and safety, as well as minimizing pollution and fuel consumption....

Websites
The international association CiA (CAN in Automation) was founded in 1992 to promote the use and development of the CAN network by providing information and expertise on its techniques, products and marketing. Annual membership costs €550 ex VAT for educational establishments, and varies according to the size of the company (€700 for less than 10 employees, up to €9,900 for more than 100,000).
Events
Conventions, trade shows, symposia and study days are generally listed on the website of the non-profit association CAN in Automation (CiA). CiA is the international organization of users and manufacturers that develops and supports CAN-based upper-layer protocols. CiA organizes webinars and publishes a newsletter with various technical, commercial and regulatory information on the CAN bus.
