First Toyota cars to include V2V and V2I communication by the end of 2015

By the end of 2015, Toyota will make a new ITS safety package available on three models in Japan. This package uses V2V and V2I communication to provide drivers with the kind of safety information that cannot be picked up by onboard sensors. The new ITS safety package uses Japan’s standardized ITS frequency of 760 MHz to receive and share data transmitted by external infrastructure and other vehicles.

By the end of 2015, Toyota will make a new ITS (Intelligent Transportation System) safety package available on three models in Japan. The package, named ITS Connect, uses vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication to provide drivers with the kind of safety information that cannot be picked up by onboard sensors. This includes traffic signal information and information about the presence of vehicles and pedestrians in blind spots. ITS Connect uses Japan’s standardized ITS frequency of 760 MHz to receive and share data transmitted by external infrastructure and other vehicles. The company claims that equipping ITS Connect on these three models will make Toyota the world’s first automaker to bring a driver assist function that uses a dedicated ITS frequency to market. By steadily expanding the range of vehicles equipped with ITS Connect, Toyota hopes to help reduce the number of accidents that occur near intersections. In Japan, this kind of accident accounts for roughly 40 percent of all traffic accidents, according to statistics from Japan’s National Police Agency.

V2V communication implies the direct exchange of information among vehicles and includes Communicating Radar Cruise Control and Emergency Vehicle Notification. When communicating radar cruise control information, the system responds almost instantaneously to the acceleration and deceleration of other equipped vehicles. This allows two or more vehicles to maintain a safe distance and minimize speed fluctuations, making traffic flow smoother. When an ambulance implements Emergency Vehicle Notification and is sounding its siren nearby, the system notifies the driver with an audio alert, and displays the approximate location and distance of the emergency vehicle, as well as the direction in which it is moving.

V2I communication enables the exchange of information between vehicles and static infrastructure nodes and includes Right-Turn Collision Caution, Red Light Caution and Signal Change Advisory. With Right-Turn Collision Caution, drivers are warned by an audio and visual alert while waiting to turn right at an intersection fitted with the appropriate equipment under the following circumstances: if they take their foot off the brake and start to move forward when another car is approaching from the opposite direction, when a pedestrian is crossing the road to the right of the vehicle, or when there are other potential hazards the driver may not have noticed. With Red Light Caution, when approaching an intersection fitted with the appropriate equipment, if the signal is red and the driver does not ease off the accelerator, the system will warn the driver with an audio and visual alert. With Signal Change Advisory, when stopping at a red light at an intersection fitted with the appropriate equipment, a display counts down the remaining time until the traffic light changes.
