Treating traffic like a system
Carol de Vries, vice president of automotive R&D at NXP, said that cars are already heavily networked internally with Flexray for safety critical applications being augmented by automotive Ethernet.
NXP already developed the ATOP module (Automotive Telematics On-Board Unit Platform) which was used in an eCall trial in 2011. The eCall initiative, expected to be Europe wide by 2015, aims to deploy a device installed in all vehicles that will automatically dial 112 in the event of a serious road accident, and wirelessly send airbag deployment and impact sensor information, as well as GPS coordinates to local emergency agencies.
The NXP ATOP module can be either embedded in auto electronics or mounted as an aftermarket solution. Besides the eCall duties it can be extended for a variety of services including road-pricing, stolen vehicle tracking, pay-as-you-drive, eco-navigation. Helping with driving patterns can significantly improve fuel consumption and reduce CO2 emissions. "Co-operative driving can prevent 35 percent of 'shockwave' traffic jams, said de Vries.
An example of how automotive IoT could roll out is provided by the Smart-in-Car project. This projectinvolves 200 cars around Eindhoven equipped with ATOP modules. These modules are able to upload the vehicles' universal CAN networking data to the cloud where it can be sifted and compiled.

Treating a city's traffic like a swarming system can bring economic benefits, says NXP
The trial, begun in May 2011 with a budget of 1.5 million euro (about $2
million) and just about to end, was conducted by NXP with IBM, Beijer
Automotive, Nokia, the Technical University of Eindoven and the Dutch
government and local authorities, amongst others.
