GM Demonstrates China Connected Vehicle V2X Tech in Shanghai
During this week’s 2016 SAE-China Congress & Exhibition in Shanghai, General Motors China is demonstrating the interoperability of China connected vehicle (V2X) application layer standard for the first time. To do so, GM has partnered with the China Academy of Information and Communications Technology (CAICT), Tsinghua University, Chang’an Auto, Yanfeng Visteon, and Shanghai International Auto City.
The presentation included demonstrations of Blind Spot/Lane Change Warning, Forward Collision Warning, Intersection Movement Assist, and Special Vehicle Avoid Notification.
GM and its collaborators are working to create a set of communication standards that will underpin any intelligent transportation system (ITS) that uses connected vehicles.
A working group composed of people from GM, Tsinghua University, and Chang’an Auto are developing the V2X application layer standard, with the support of SAE-China and C-ITS. After first completing a definition and demand analysis of the applications, the group is now working to define the required message set dictionary and data exchange standards.

The required message set dictionary stipulates the content, format, and coding methods for data exchange at the application layer, while the data exchange standards stipulate the time, frequency, data requirements, and interface definition needed for data exchange.
GM China says that the working group’s demonstration in Shanghai improved and verified the required message set dictionary and data exchange standards at the V2X application layer. It also generated important reference data to bolster China’s continued research into intelligent and connected vehicles (ICVs) as the country looks towards future deployment.
“V2X has the potential to mitigate many traffic collisions and improve traffic congestion by sending and receiving basic safety information such as location, speed and direction of travel between vehicles,” said Dr. John Du, director of GM China’s Science Lab.
“For this type of cooperative technology to work, it is essential that common standards and a security framework be established,” he added. “We are pleased to bring to China the expertise that we have gained from developing and promoting V2X technology in North America and Europe to drive ICV development in China.”
