TORONTO, ON. – Starting next year, some of Toyota Motor Corporation's new models will be compatible with advanced vehicle-infrastructure cooperative systems that use a wireless frequency reserved for intelligent transport systems (ITS).
The automaker says this compatibility will be offered as an option for the “Toyota Safety Sense P” active safety package that will be made available in 2015 on select new models sold in Japan.
The systems will use the dedicated ITS frequency of 760 MHz for road-to-vehicle and vehicle-to-vehicle communication to gather information that cannot be obtained by onboard sensors.
At intersections with poor visibility, information about oncoming vehicles and pedestrians detected by sensors above the road will be relayed via road-to-vehicle communication; information about approaching vehicles will also be relayed via vehicle-to-vehicle communication, with audio and visual alerts warning drivers when necessary.
In addition, Toyota says its newly developed communicating radar cruise control (CRCC) feature lets vehicles in front and to the rear keep safe distances between one another on highways.
CRCC uses Toyota's existing forward-facing, millimeter-wave radar to detect distances and speeds between vehicles.
“The addition of acceleration and deceleration information from preceding vehicles (obtained via vehicle-to-vehicle communication) significantly enhances tracking performance. In addition to making highway driving safer, this helps reduce traffic congestion and enables more fuel-efficient driving,” the automaker says.
Toyota develops ITS-compatible interfaces with government ministries and agencies and private companies with the aim of launching them as soon as practically possible.
In 2013, the automaker says it participated in the ITS Green Safety public-private collaborative demonstration project to assess the effects of such systems. It will participate in the ITS Connect Promotion Consortium to support the development and smooth introduction of such systems and their widespread adoption.
“Toyota believes that the ultimate goal of a society that values mobility is to eliminate traffic fatalities and injuries.
“Toyota is firmly committed to a wide range of initiatives addressing traffic safety, ranging from the development of ever-safer vehicles and technologies to helping create a safe traffic environment and engaging in educational activities.”
