Imagine a future where vehicles are able to
communicate with each other. This vehicle-to-vehicle
or V2V technology would provide drivers with
crucial information when they need it and
provide them with a warning of a potential
crash. V2V provides drivers with 360 degree
awareness of similarly equipped vehicles within
a range of approximately 300 meters or 984
feet. This secure system keeps personal information
anonymous and does not track your vehicle.
Drivers will receive warnings that inform
them of potential hazards through a visual
display, seat vibration or tone. These are
only warnings. The driver remains in control
of the vehicle at all times. These warnings
can help drivers respond quickly to avoid
potential crashes. For example, the Intersection
Movement Assist application warns drivers
when it's unsafe to enter an intersection.
The Do Not Pass application warns drivers
when it is not safe to pass a slower moving
vehicle. The Emergency Electronic Brake Light
application notifies the driver when an out-of-sight
vehicle several cars ahead is braking.
The Blind Spot Warning application allows drivers
to virtually see what's happening in his or
her blind spots. These are just a few of the
apps that may be available to help prevent
car crashes in the near future. So how does
V2V work? V2V uses a wireless protocol similar
to wifi called dedicated short range communications
or DSRC, for short. When DSRC is combined
with GPS technology the result is a low-cost
V2V communication system that provides a 360
degree view of similarly equipped vehicles
within communication range.
Transmitted messages common to all vehicles include: current GPS position,  vehicle speed acceleration and heading,
vehicle control information such as transmission
state, brake status, and steering wheel angle,
as well as the vehicle's path history and
path prediction. V2V does not include current
advanced technologies: navigation, internet
access, assistant services, rear-view cameras,
and other advanced technologies. Now it's
your turn.
Are you ready for V2V technology in your next vehicle?
