New car GPS Navigator can reduce the energy consumption of electric vehicle in twice

Recently, researchers from the University of California riverside College of engineering announced the development of a new navigation tool that will reduce the energy consumption of electric cars by as much as 51 percent.

The new instrument navigation system "eco-routing" – takes into account a wide variety of data, including traffic information and other traffic conditions, received in real time, the type of road, class of road etc. First, the system was tested on the electric vehicle Nissan Leaf sample 2013 100 journeys on three routes of varying length (from 30 to 37.3 km) around the College campus in riverside. Here are some of the results of these tests:

— on the route that the navigation system determined as being the minimum time, the energy savings amounted to 25 to 51 percent. The route length was increased from 3 to 19 percent;

— on the shortest route the consumption decreased by 5 to 25 percent. However, it increased the travel time of the route – from 8 to 96 percent.

The researchers then incorporated the data road tests in the algorithm of the navigation system eco-routing and spent more than 4000 trips on the same routes, but with the use of numerical simulation. According to project Manager, researcher Guoyuan Wu, significant savings in energy consumption new system of eco-routing compared to conventional navigation tools, shows considerable potential for commercialization of this technology.
