Vehicle standards for safety and emissions differ widely from one region to another. “Car manufacturers cannot develop one car and sell it across the world,” says Filip Sergeys, head of intelligent transport systems (ITS) government relations and regulations at Honda Motor Europe. “We have to develop a specific vehicle type for each region.” Now, the IoT is offering the automotive industry and government transport departments the opportunity to create global standards for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication, with the aim of reducing accidents and traffic congestion. It is still early days, but the progress so far looks promising.
In 2002 car manufacturers established the Car 2 Car Communication Consortium with the aim of creating open European standards for V2V and V2I communication. The consortium with its 60 members, consisting of car manufacturers, suppliers and research institutes, is now close to finalising the messaging standard, named the Co-operative Awareness Message (CAM), which allows vehicles to speak the same ‘language’.
Efforts to harmonise standards are also proceeding in other regions of the world. For example, the European Commission’s Directorate-General for Communications Networks, Content & Technology (“DG Connect”) is working with the US Department of Transport to bring the European CAM standard closer to the US Basic Safety Message (BSM) standard. Although the standards will not be identical, they will be close enough to make it feasible to use a single hardware platform for both. Honda has also been actively pushing to use the European standards in Japan. “It won’t be a global standard, but it will at least cover the three major automotive markets,” says Mr Sergeys.
Although the automotive industry is leading the effort to create harmonised IoT standards, government departments—including DG Connect, the US transport department and the Japanese Ministry of Land, Infrastructure, Transport and Tourism—are also playing a crucial role. “The efforts by the authorities to push this have been very instrumental and very helpful,” says Mr Sergeys.
