Bosch already supplies a system for several vehicles in the Nissan model range that takes ecological and economical aspects into account when selecting the best possible route. In the future, it will also be possible to analyze vehicle- and driver-specific profiles, which will make it possible to determine the choice of routes that use the least fuel.

In-company studies conducted by Bosch reveal that this can reduce fuel consumption by approximately seven percent so that the eco route gets the driver to the selected destination in the most economically and ecologically friendly way possible, using less fuel and producing fewer CO2 emissions.

Navigation systems offer vehicle drivers the choice between a number of different route options. When only one option is used to calculate the route, the results often display very specific characteristics.

The next step in development for the engineers in the Bosch Car Multimedia division plans to further improve this successful method by defining profiles that include different vehicle-specific data and driving behaviors.

In addition to the fuel required for the actual route, this method also takes the extra fuel required for the acceleration processes anticipated into account, including such parameters as the vehicle make and model – with its size, weight, average consumption and drive configuration – as well as the driver's driving style. Whether the driver prefers a more "racy" style with frequent acceleration or tends to strictly observe the recommended speed limits and drive more defensively in moving traffic – this data is processed accordingly and used to optimize the eco route.
