Not be outdone by DaimlerChrysler, GM shows off its own communications system

It looks as though DaimlerChrysler isn't the only automotive company looking at car-to-car communications systems. General Motors has announced its new vehicle-to-vehicle (V2V) system which is currently being tested on Cadillac, Chevrolet, Opel and Saab models in Germany.

Like DaimlerChrysler's system, V2V uses Wireless LAN (WLAN) technology, GPS and a vehicle’s numerous computer controlled active safety systems to relay data back and forth between vehicles. The system is capable of relaying such data as Emergency Brake Warning, Blind Spot/Lane Change notification (with accompanying blinking LEDs in the side view mirror and vibrating driver's seat), Forward Collision Warning and Emergency Vehicle Warning (with location and direction of travel for the emergency vehicle).

"Driving is a very complex task. Knowing where the other guy is and where he’s headed can be as critical as being in control of your own vehicle," said GM's Hans-Georg Frischkorn. "With V2V technology, we intensify the driver’s awareness of his environment to improve road safety, without any distraction to him and certainly without reducing his level of control. This sixth sense lets drivers know what’s going on around them to help avoid accidents and improve traffic flow."

Whereas DaimlerChrysler's system will be employed in high-end Mercedes vehicles at first, GM is using off the shelf components to drive down costs and implement the system on as many vehicles as possible.

Another flawed execution

There are some nice safty advantages that could come out of this but until the auto companies talk to one another and come up with a unifide standard for communication, this is just for bragging rights.

For example your on some twisty road in a nice shiny benz, you go flying around a turn and slam into a tree that fell over on the road. The benz sends out a warning and the escalade behind it says "huh I dont understand your language" and then BAM everyones dead.

Good point! And its giving out indications that properly trained driving reflexes are not prepared to handle. Unless busy rich execs learn to drive in a box and learn to react to strobing LEDs and other stimuli (doesnt make a difference in your example of course). I dont want to be sharing a road with those fools. What happened to good old defensive driving, constant observation and proper anticipation? And what the hell is the vibrating seat supposed to indicate? "you've drifed onto the oncoming carriageway due an attention deficit caused by executive stress, so SAAB is giving you a complimentary butt massage before you get creamed"?

These are just prototype proof-of-concept systems, so at this point no standards are needed. The purpose of these systems is to gain a thorough understanding of requirements and to get some experience with developing these systems, before a real production system is developed.

The automotive industry has a good track record of developing vehicle communications standards and making devices interoperable, although we may not be aware of that at a consumer level. To develop V2V systems will require collaboration between automotive companies and governments (since these systems will also communicate with fixed infrastructure systems as well), probably under the guidance of organizations like SAE, ISO, etc. The market potential is large, and the need for interoperability is obvious to all parties - so standardization and commonization will happen.
