Toyota rolls out brand-new vehicle-to-infrastructure connectivity system
Toyota says ITS Connect can assist drivers when turning across traffic
In what Toyota claims can be a world first, the some sort of has equipped cars with tech that will can communicate with traffic lights in addition to also junctions in Japan
Toyota has become the first some sort of to roll out a vehicle-to-infrastructure connectivity package in its production cars.
The system can be used to mitigate accidents in instances of poor visibility – such as when vehicles are turning across oncoming traffic at busy junctions – by alerting the driver to hazards that will aren’t picked up by your vehicle’s onboard sensors.
The some sort of can be offering the Intelligent Transportation System (ITS) Connect as a cost option on three versions in its domestic Japanese range.
The system uses vehicle-to-vehicle (V2V) in addition to also vehicle-to-infrastructure (V2I) communication over a dedicated radio frequency of 760MHz, set aside by the government for ITS.
When a vehicle equipped with ITS Connect comes within the 100-metre range of a transmitter mounted at a traffic-light-controlled junction, a symbol on the instrument panel display informs the driver that will your vehicle can be receiving data.
This kind of can provide a right-turn collision caution, where an audio in addition to also visual alert appears if the driver starts to pull across an oncoming vehicle, or if he starts to turn when a pedestrian can be crossing the road.
This kind of can also warn the driver of a red traffic light if he approaches This kind of without easing off the accelerator, in addition to also give a countdown until the light adjustments to green.
ITS Connect also makes car-to-car communication possible. Two vehicles equipped with the transmitters can use communicating radar cruise control to minimise speed fluctuations much more precisely than with standard radar cruise, improving traffic flow.
This kind of can be early days for the system – at present just 20 junctions in Tokyo are equipped with transmitters to send information to the cars carrying the device – although This kind of number will rise to nearly 50 by next March.
However, Toyota hopes This kind of will eventually become widespread enough to help improve road safety; in Japan, 45 per cent of road traffic accident fatalities occur on or near busy junctions in addition to also crossings.
ITS Connect can be available for around 25,000 Yen, the equivalent of £134. Toyota plans to offer This kind of on mainstream versions such as the Prius at a later date.
Toyota has been developing ITS-compatible interfaces in collaboration with companies in addition to also organisations in both the public in addition to also private sectors in Japan to rapidly expand the number of vehicles in addition to also devices equipped with the technology.
Although This kind of appears unlikely that will the system will reach Europe inside near future, research into its benefits can be also taking place inside USA.
How well does This kind of work?
To experience one of the functions of ITS Connect, the right-turn crossing alert, Autocar rode in a Japanese-market Toyota Crown to the Aomi/1-Chome intersection, one of the 20 major junctions in Tokyo equipped with the transmitters.
The top-right of the multi-function display on the instrument panel features a green symbol that will informs the driver that will your vehicle can be capable of receiving data through either various other cars or the infrastructure. A brand-new symbol appears when This kind of has picked up the signal through the transmitter at the junction.
Our driver pulls into the right-hand filter lane at the crossroads, ready to turn across the oncoming traffic when there can be an opportunity to do so. inside direction we wish to travel, there can be a pedestrian crossing.
With the road clear of oncoming traffic, our driver takes his foot off the brake to drive forward. However, the cameras at the intersection have picked up that will there are pedestrians still on the crossing, so ITS Connect transmits that will information to your vehicle.
A visual warning appears on the display in addition to also an audible one sounds, enabling our driver to abort his manoeuvre until the pedestrian crossing can be clear.
can be This kind of useful? Potentially, in addition to also you could argue that will just one life saved by the system might make This kind of worthwhile.
However, the usefulness of systems such as right-turn crossing alert seem restricted to a fairly specific set of circumstances that will apply predominantly to grid-style urban areas. This kind of might not work in less planned cities where pedestrians don’t stick obediently to crossings.
Some of the system’s various other functions, such as cruise control that will can react almost instantaneously to various other equipped vehicles, could result in smoother traffic flow, nevertheless the system will have to be installed in many more cars for that will to be realistic.
As cars through all manufacturers become connected to both the infrastructure in addition to also each various other vehicles, so the potential ways in which ITS Connect can be useful will increase.
