Audi uses high-res map to improve fuel efficiency

Audi predictive efficiency assistant

Audi has announced the company is developing a new high-resolution map that will feed data into its predictive efficiency assistant system that in turn leads to better fuel economy.

A current example of the potential of this data is the predictive efficiency assistant in the new Audi Q7. It utilises information about the topography to get the car to its destination with greater efficiency and convenience. High-resolution maps will also play a key role in piloted driving.

“The importance of high-resolution, three-dimensional maps will continue to grow in the future,” explains Prof. Dr. Ulrich Hackenberg, Audi Head of Development.

“Here we primarily use the data in situations in which a precise prediction is crucial – for example, data on expressway interchanges, road splits and entrance and exit ramps.”

Audi is working on the navigation map of the future with strategic partners such as Dutch map and navigation supplier TomTom – utilising various technology platforms in the process. The next generation of the Audi A8 will be a front-runner in piloted driving technology and the use of high-resolution maps.

Today, Audi customers can already realise significant benefits from precise map materials. The predictive efficiency assistant in the new Audi Q7 already utilises highly precise route data that includes information on elevation profiles – it works with this data even while the driver is not actively using navigation. If desired, the system can also be used to help economise on fuel. It offers practical fuel-saving tips to drivers in situations in which reducing speed makes sense.

The predictive efficiency assistant recognises curves, roundabouts and intersections, descents and ascents, as well as municipality border signs and speed limit signs – often before the driver even sees them. Audi claims drivers who fully utilise these features can reduce fuel consumption by up to ten percent.
