Car-to-car & Car-to-X communication


Car 2 Car communication

Technology that would allow cars to talk to each other—to help prevent accidents and improve traffic flow.


Many high-end cars already come with sensors capable of spotting a vehicle in a driver’s blind spot, or warning that the car is drifting out of lane. However, these technologies, which use radar, laser, or video sensors, have a limited view. Car-to-car communications could provide even more sophisticated earlier warnings—for example, when a car several vehicles ahead brakes suddenly.

Thanks to technologies such as Intel’s M2M (Machine-to-Machine), they’ll be able to share data with other cars on the road and warn drivers of accidents, as well as figure out alternate routes based on real-time information — which in turn will help cut down on traffic and increase safety on the road.

Car 2 X Communication 

There’s some overlap between car-to-car and car-to-X technology. BMW prefers car-to-X, as they’re looking into designing a system that allows cars to communicate with other systems outside of those in vehicles.





In Germany, the simTD research project (Safe Intelligent Mobility - test field Germany) is examining the everyday practicality of Car-to-X communication under the direction of Daimler. simTD uses wireless technology based on the conventional WLAN standard and integrates UMTS and GPRS mobile technologies to enable any vehicle to generate and transmit important information for the traffic on the road.

This research project is known as PROTON-PLATA (programmable telematics onboard radio).
The PROTON-PLATA project is researching whether SDR (software defined radio) is the possible answer — technology which will allow all of these systems to be implemented in a single hardware unit.




Twirling battery

Twirling battery offers emergency power

An innovative design for a 'twirling' battery could help get you out of a fix the next time your mobile runs out of power, although sadly the team behind it has yet to produce a working prototype.



The design, developed by Song Teaho and Hyejin 





Providing around two minutes of talk time for a 130 twirls - which shouldn't take too long to complete - the system is designed to provide a way of getting power to the mobile for a last call, such as when you need a taxi after a long night out. Alternatively, if you're waiting for an important text, a hundred and thirty twirls will get you around twenty five minutes of standby time.



We are really happy to see these new concepts and we hope that won’t remain just a useful design but will become a reality.
