Ford is working with MIT, Stanford to build “common sense” into self-driving cars

Ford Motor Company is teaming up with the Massachusetts Institute of Technology and Stanford University to research the future brains of its autonomous cars. Projects like Ford’s research vehicles are putting the sensors and computing power into cars that would allow them to read and analyze their surroundings, but these two universities are developing the technology that will allow them to make driving decisions from that data.
“Our goal is to provide the vehicle with common sense,” Ford Research global manager for driver assistance and active safety Greg Stevens said in a statement. “Drivers are good at using the cues around them to predict what will happen next, and they know that what you can’t see is often as important as what you can see. Our goal in working with MIT and Stanford is to bring a similar type of intuition to the vehicle.”
In December, Ford unveiled its latest research vehicle, a Ford Fusion Hybrid equipped with Lidar (laser-radar) rigs, cameras and other sensor arrays, all intended to generate a real-time representation of the world around the car. Such a car can “see” in all directions, allowing it not only to take in far more stimuli than even the most alert driver, but also to react to that information far more quickly. That’s where Stanford and MIT come in.

MIT is developing algorithms that will allow an autonomous driving system to predict the future locations of cars, pedestrians and other obstacles. It’s not good enough for a car to merely sense the location of nearby vehicles when it switches lanes or swerves to avoid an accident. It has to know where those vehicles will be a split-second later. Otherwise the car will avoid one accident only to cause another.
That means not only measuring other vehicles’ current speed and trajectory but anticipating how their drivers – or their autonomous vehicle systems – will react to the situation. Basically MIT is trying to create a vehicle brain smart enough to assess risks and outcomes and navigate its course accordingly.
Stanford is doing something a bit different. It’s trying to extend the sensory field of the car by helping it see around obstacles so it can react to dangers the driver can’t immediately see. Stanford and Ford didn’t offer any specifics on just how they would accomplish that feat, by my bet is it has to do with Ford and the automotive industry’s work on inter-vehicle networking.
Cohda Wireless autonomous car
Future autonomous cars won’t just be able to sense their surroundings, they’ll be able to communicate with other vehicles using a secure form of Wi-Fi. For instance, Australian startup Cohda Wireless is developing to vehicle-to-vehicle networking technology that would allow two cars to let each other know they’re approaching one another at a blind intersection.
Ford and other major automakers are working with the University of Michigan and the National Highway Traffic Safety Administration to build vehicle-to-infrastructure grids that would allow cars to tap into highway sensors, giving them a kind of omniscient view of the overall road. With such technology other cars could reveal their intentions before they even take action, making other connected vehicles much more responsive. They could also share their sensor data, so even if only one of the cars far ahead of you is connected to the vehicle grid, that lone vehicle could still tell you what the other cars around it are doing.
While every major automaker is working on autonomous driving technology, Ford has been particularly aggressive. In a recent interview, executive chairman Bill Ford told me how the automaker is trying to use connected vehicle technology to propel the company into a new golden age of automotive innovation.

BT trials new network tech for ‘Internet of Things’

BT
BT has begun trialling a new technology from tech company Neul on machine-to-machine (M2M) communications using ‘white space’ technology.
These tests involve sending traffic information to and from moving vehicles via gaps – or ‘white spaces’ – in the frequencies bands used for digital TV broadcasting.
White space networking could enable up to 50 billion devices to be connected wirelessly to the internet by 2020, say BT.
“The internet of things market has huge potential, but existing short-range and cellular networking technologies are unable to meet the requirements of many applications we see,” Mark Harrop, director of mobile strategy at BT, said. “A networking technology that can provide deep indoor coverage, last for many years from a single battery, is simple to use, and comes at the right price point is essential for realizing the true potential of the internet of things.”

Bins that ask to be emptied

BT has been conducting these trials since late last year, but now they are using the new NeulNET system. The NeulNET system provides two-way, wide area M2M networking that Neul claims “far outreaches today’s GPRS, 3G, CDMA and LTE WAN solutions”.
The NeulNET system uses an antenna-equipped base station that can provide wireless coverage in a radius of up to five kilometers, along with terminal modules that can run for up to 15 years on two AA batteries and can communicate from deep within buildings or underground.
The system, delivered by Neul as a cloud-based managed communication service, can operate in either licensed or unlicensed spectrum, and across a wide range of frequency bands.
Neul adds that it expects to announce further deployments of its NeulNET technology throughout 2014. It says the system could enable smart-city applications ranging from waste-disposal bins that “ask to be emptied” to green-belt areas and farms that are monitored and watered efficiently.
