Method for preparing or drawing route from starting point to target in information or navigation system in motor vehicle i.e. car, involves computing route guided to one of filling stations to preset target

摘要

The method involves transmitting current and valid fuel prices at various filling stations by a wireless communication medium to a motor vehicle. A route (5) is taken into account while choosing routes offered to a driver. The route guided to one of the stations is computed to a preset target, where the route offered to the driver is selected such that the energy costs calculated for total distances are minimized with simultaneous consideration of the respective energy prices and additional consumption connected with the associated detours to the respective filling stations. An independent claim is also included for an information or navigation system comprising a processing unit.
