DENSO to Begin Vehicle-to-Vehicle and Vehicle-to-Infrastructure Technology Field Tests in China

DENSO is globally researching and developing V2X technology

DENSO Corporation, 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, 2012. While this is DENSO’s first V2X technology field test on public roads in China, the company 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 & 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 Field Test in China: Emergency Vehicles

V2X technology will be used to wirelessly communicate the vehicle position and speed of emergency vehicles – like 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 and V2X Technology

DENSO has been globally researching and developing V2X technology since 2003. One of our central focus points is Dedicated Short-range Communications (DSRC), which is the primary enabling component of V2X communications.

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 is globally committed to helping bring V2X technology to market in an effort to greatly improve safety, improve traffic flow and reduce CO2 emissions.
