GM demonstrates vehicle-to-vehicle (V2V) wireless communication
by Mike Adams, the Health Ranger, NaturalNews Editor
GM's V2V technology gives the driver visual and "sense of touch" feedback if there is an impending collision. Collisions are prevented by alerting the driver or by automatically stopping the vehicle.
On Thursday, General Motors demonstrated a vehicle-to-vehicle, or V2V, wireless communication system that alerts you when a collision is imminent.
The automaker equipped regular Cadillac STS sedans with wireless and Global Positioning System antennae and computer chips that allow the cars to communicate with other vehicles with similar equipment.
The wireless technology in one car detects the presence of the other two Cadillacs and avoids collisions by either alerting the driver of danger or by automatically stopping the vehicle in an emergency.
In terms of an alert, the driver's seat gives off a heavy vibration to the left leg if the driver signals to enter the left lane, unaware of a car in his or her blind spot.
Such a warning is an example of what, in the auto industry, is called "haptic feedback"--feedback related to the sense of touch.
"We're trying to standardize the wireless communication between cars, and we hope other car manufacturers will follow.
This would be the reinvention of the vehicle," said Priyantha Mudalige, senior research engineer at GM and one of the four engineers who built the wireless safety system.
That's because it will likely take that long to sign agreements with other manufacturers and with standards agencies like the Federal Communications Commission.
A wireless antenna on top of the vehicle also receives up to 100 different data points from the car's internal network, including information on speed, braking and the use of turn signals.
The car's software constantly calculates, in real time, other vehicles' positions and speeds.
GM's proprietary algorithm, called the "threat assessment algorithm," also processes data from the GPS and the car's computer network, along with messages from other cars, in order to fire off warnings and prevent collisions.
