Automotive and Aerospace Standards home
Controller Area Network (CAN) standards cover the CAN bus, designed and implemented to allow different components within a vehicle to communicate with each other without needing a host computer. As a textbook example of interoperability, standardization is critical to the functioning of the system as a whole, especially with the consideration that not all the cooperating parts will be made by the same manufacturer. Specified in ISO 11898, this series of standards has been implemented worldwide and the concepts within extend beyond their original design for automotive applications into other industrial fields.
Traffic and Travel Information standards go hand in hand with Intelligent Transport System standards, working together to further the goal of seamless integration between devices and data manipulation for integrated transport information, management, and control. Developed by SAE International and the International Organization for Standardization (ISO), these standards strive for interoperability across the world.
Intelligent Transport Systems (ITS) standards cover reference model architectures and data formatting. Because of the wide array of different technologies employed in intelligent transport systems, and the necessary smooth interaction between the vehicle, its parts, outside sensors, the network that draws information from those sensors, and the manipulations that occur later makes standardization a key component of the system as a whole.
