Green Eco Routing, Navigation and your car computer

Some intelligent forward thinking researchers over at Hitachi, Xanavi, and Nissan have collected some data on ecological green routing that claims a 9% fuel cost savings on a test route. This technology is still in its infancy, but this is a perfect example of where a car computer can be used to accelerate development and deployment of technology. Implementing ecorouting will require Intense processing on the client or cloud for the complicated routing algorithms that factor in all the newly available data points:

Traffic & Flow speeds

Elevation changes and altitude

Road quality (smooth vs. rough)

Wind (eventually)

The cloud or development computer can also be used to coach the driver into more efficient acceleration and braking techniques which a lot of hyper milers are already using.

Eventually I imagine this type of data would help local governments prioritize road resurfacings and traffic control timings to help their citizenry become greener.

It seems like one of the key pieces to making this work would be accurate elevation Data. The paper I mentioned above used 50m resolution data from the government. One of the key data providers for elevation data seems to be intermap with 5m horizontal resolution and +/1 1m vertical. Check out their comparison chart to NASA data.

Decided to idle-necro here to cover this as someone who has been closely looking at Ford's implementation and ultimately passed on the idea of a custom built CarPC in favor of their OEM implementation.

With the latest 2010 models with 911 assist, vehicle health reporting, and whatnot, the non-navigation vehicles that call out via cell to the automated voice response number DO offer real turn by turn directions. The cars come with built in GPS even without the navigation system. Ford has licensed tech from Airbiquity which basically acts as a modem over the cellphone voice channel so once you have went through the voice prompts and determined a destination it will mute the audio and go into the data transfer mode (capable of 800 baud, good enough for the nav data Sync needs). This is noticeable when the voice switches over to the Sync prompt saying 'Downloading'. Once the data is downloaded it will disconnect the call and then the Sync interface in the car will do the navigation by audio and through the minimalist character display on the radio. So you don't need an expensive nav system, just a bluetooth phone and enough voice minutes.

Those vehicles with Navigation systems of course do the work internally (other data such as sports scores and gas prices are provided via Satellite through Sirius. Known as the Travel Link option.).

There's a few videos on youtube that actually demonstrate this functionality with the turn by turn directions provided via phone.

Honestly if your driving on the road anyways, why would you even look at the display? Its already speaking to you!

I just dont think that SYNC is any type of big deal. The Car PC is just way ahead. We have plugins that can easily do what the sync does. I am sure someone will create a plugin that tells you scores on the phone and then displays it on the screen. I mean most of use voice control, I am sure that someone will make something that we simply go to a sports site, then tell the PC to read it aloud for us. There are just so many routes the PC can go.
