DENSO Corp., in collaboration with Tongji University (Shanghai), will begin testing vehicle-to-vehicle and vehicle-to-infrastructure (V2X) technology on public roads in Taicang, Jiangsu Province, China on March 15. While this is DENSO's first V2X technology field test on public roads in China, the company says it has been conducting field tests in Japan, the United States and Europe for the past several years.
"Due to the rapid increase in vehicles on China's roads, chronic congestion and safety are the two largest issues, particularly in the larger cities," said Yasushi Yamanaka, DENSO's executive director in charge of the engineering research and development center. "V2X technology, which allows cars to wirelessly communicate with other cars and roadside infrastructure, such as traffic signals, is expected to help alleviate traffic congestion and help prevent collisions."
V2X technology will be used to wirelessly communicate the vehicle position and speed of emergency vehicles, such as ambulances and fire engines, to the surrounding vehicles and roadside infrastructure. When an emergency vehicle is approaching, the technology will change the traffic light at intersections and alert surrounding vehicles to switch lanes. The experiments are intended to give the right-of-way to authority vehicles in case of emergency and to help prevent vehicle collisions.
DENSO began globally researching and developing V2X technology in 2003. At its test track in Japan, DENSO has simulated an urban road environment to check the communication performance and to develop and evaluate applications with actual vehicles. The results have been used to develop in-vehicle devices, which have been provided to various demonstration experiments involving collaboration among automakers and government agencies in Japan, the U.S., and Europe.
DENSO is among the suppliers supporting the U.S. Department of Transportation's Connected Vehicle program
field-testing of V2X technology. The U.S. is due to make a decision 2013 whether to standardize it on future cars and trucks.
DENSO’s global V2X technology experts will be speaking at the Telematics V2X for Auto Safety and Mobility conference, which will bring industry experts together to discuss and investigate the full potential of vehicle-to-vehicle and vehicle-to-infrastructure (V2X) technology on March 20-21, at the Hotel Baronette in Novi, Mich.
DENSO V2X experts Roger Berg, vice president of Wireless Technologies at DENSO International America Inc., and Tim Leinmuller, chief engineer of Information and Safety Systems at DENSO Automotive Germany, will participate in four panel sessions on March 20: Exploring Today’s V2X Offerings; Desirable Business Models and Probe Data Opportunities; V2X and ADAS: Complementary Technologies to Improve Road Safety; and Learn Lessons from Europe: Partnership Opportunities to Implement V2I.
