Mercedes launching car-to-car communications

with one comment

Vehicle-to-vehicle communications are a fundamental pillar of autonomous, self-driving cars. Once vehicles can exchange data with each other and the greater driving infrastructure, they’ll be able to “see” and adapt to driving obstacles more completely, preventing accidents and delivering more efficient driving. Mercedes plans to be the first automaker to bring a Car-to-X vehicle-to-vehicle communications system to market.

When fully equipped with the latest technologies on offer, modern cars can already do much of the driving themselves. They can accelerate, maintain following distance and brake for traffic. They can help the driver maintain lanes. They can monitor hazards and obstacles such as pedestrians, rear cross traffic and blind spots. They do all these advanced activities with the help of onboard camera, sensor, laser and radar systems…

Vehicle-to-vehicle communications will serve to expand vehicles’ monitoring and autonomous driving capabilities, gaining a more comprehensive picture of surrounding road conditions like traffic and accidents. Being able to gather and send information about driving conditions will enable cars to analyze, adapt and navigate independently within road systems. Such communications can also make roadways more efficient, for instance transmitting real-time traffic pattern data with traffic lights…

When equipped with Car-to-X, the Mercedes vehicle is both a receiver and transmitter of data. It can gather information from other nearby Car-to-X-equipped cars and compatible broadcast systems. For instance, an emergency response vehicle involved in accident response could send information about the location of the accident and applicable road closures. Other examples include alerts about bad weather, animals on the road, wrong-way drivers and potholes.

Once the driver sees these notifications on his infotainment display, he can react accordingly, slowing down, taking a different route, etc. For now, the system still relies on the driver to react, but it’s easy to see how it could be used to power autonomous vehicle reactions in the future.

A Car-to-X-equipped vehicle can also serve as the initiation point for notifications. It can detect and transmit some warnings automatically and includes a push-button notification system so that the driver or passenger can warn other cars of hazards.

While being the first to market gives Mercedes bragging rights, it also means that Car-to-X technology will be very limited, as only other drivers of Mercedes vehicles equipped with the technology will be using it. To help deploy it faster, Driver Kit Plus hardware will be offered on both new vehicles and as an aftermarket option for older Mercedes models. Mercedes is also working with other auto manufacturers toward future car-to-car systems that allow vehicles of all makes and models to communicate. Along with automakers like Audi, BMW and Volvo, Daimler/Mercedes is part of the Car 2 Car Communications Consortium.

For the US market they’ll probably have to include a massive multiplayer version of Angry Birds.

  1. For the U.S. market? They should also provide verbal warnings that include the phrase “Hey! You aren’t the only car on the road!”
