automobile industry goes to the V2X technology that essentially allows vehicles to communicate with each other and all devices on the road to a time and a particular place and sharing information with each other on the road. It is expected that at the end of the day, it will improve the efficiency and safety of all road users. The V2X technology includes V2V (vehicle), V2I (Vehicle Infrastructure) and V2P (Vehicle Pedestrian).
General Motors is the first automaker to bring this technology to market with its 2017 Cadillac CTS. However, before the technology can work as intended it to be, an infrastructure must be built. Outside of Europe and the United States, China is the next location that the automaker plans to promote technology.
Before building a complete V2X technology, General Motors encourages communication dedicated short range communication (DSRC) in China as a start. According to Dr. Hariharan Krishnan, GM Global R & D and electric controls Technical Research Fellow, during his recent visit to Shanghai, to move to the world of V2X, it is essential for China to allocate spectrum for connected vehicles intelligent. He added that focusing on the development of connected vehicle systems based on DSRC in other markets would save time and money in China.
spectrum dedicated DSRC technology has already been allocated by United States Federal Communications Commission (FC) in 1999. It aims to provide benefits such as fast acquisition of the network, low latency and high reliability, priority for security applications, interoperability, security and privacy. The standard maturity of DSRC was developed in the US and Europe. If used in conjunction with GPS, DSRC is able to accurately determine the position and movement of other vehicles to reach 300 meters.
