The Japanese car manufacturer Nissan announced its eco-drive support system, Eco-mode function and Navigation-linked speed control have won the ANRE (Agency for Natural Resources and Energy) Director-General’s award in the 20th annual Energy Conservation Prize.

Anybody can win this award as long as it brings important innovation to energy conservation. This includes the use of new energy- and resource-saving or high energy-efficient materials, equipment and systems for non-military use.

Nissan’s award winning system enables eco-driving at a low cost. In the future, the system will be found on a wider range of vehicles, so it is expected that it will contribute to serious energy conservation.

According to Nissan, “when a vehicle is starting, cruising and decelerating before going into a curve, this system where the engine, CVT and the navigation system are cooperated can enhance in-use fuel efficiency without any special driving skills.”

Each of the following technologies are employed in this system:

  • Smooth Acceleration Assist - assists soft acceleration which eco-drivers do with engine control.
  • Smart-rev Control - at the time of slow acceleration, identify flapping acceleration and maintain engine revolution constant to avoid uneven speed change and unnecessary fuel consumption.
  • Eco-mode Function - enhanced version of Smooth Acceleration Assist. A mode can be changed by a flip of a switch.
  • Navigation-linked Speed Control - the engine brake is optimized to reduce unnecessary fuel consumption by providing route-information via the on-board navigation system including information on the next curve and the distance to the next tollgate, in addition to information from the vehicle.
