A navigation device includes: a position detecting means; a remaining energy level detecting means; a storage means for storing map information including position information of a charging point of a drive energy; an energy consumption amount calculation m...

According to the present invention, at least one route that satisfies a route search condition received from an information processing terminal and information distributor identification information for identifying an information distributor is created, gr...

An object of the invention is to predict energy consumptions of a vehicle, using geographic characteristic values which are independent from particular driving patterns and vehicle parameters and unique to respective links. A navigation server (1) predicts...

A car navigation system solves the problem that the emission test cycle fuel consumption rate indicates the energy consumption per unit distance covered following a prescribed emission test cycle procedure, and therefore, cannot produce a highly accurate p...

The method involves determining a route in a navigation system from a starting point to a destination, whereby the navigation system especially proposes a route for the user of the navigation system, whereby the a factor that influences the energy consumpt...

A vehicle fuel tank sensor (2) system (1) is connected to a GPS navigation system (4) and displays a route to a filling station and when the fuel level falls below a threshold with automatic route guidance activation and selection of a station on the road ...

The device has a navigation system (1-6) and a sensor (7) to determine the remaining fuel quantity in the vehicle. The navigation system detects and evaluates signals from the fuel sensor. When the fuel quantity drops below a minimum amount, the navigation...
