Abstract

A navigation apparatus is provided which displays an own-vehicle driving condition without making it difficult to view a map display. The navigation apparatus includes own-vehicle location determination means 1 that determines a location of an own vehicle; a map database 11 having map data recorded therein; vehicle data acquisition means 6 that acquires vehicle data; a displaying means 5 that displays on the map data an own-vehicle mark indicating the location of the own-vehicle; and data processing means 13 that determines a driving condition using the vehicle data, to thereby vary the own vehicle mark, wherein the vehicle driving condition is represented by means of the own vehicle mark.

Claims

1. A navigation apparatus comprising:

an own-vehicle location determination unit that determines a location of an own vehicle;

a map database having map data recorded therein;

a vehicle data acquisition unit that acquires vehicle data;

a display unit that displays on the map data an own-vehicle mark indicating the location of the own vehicle; and

a data processor that determines a driving condition using the vehicle data, to thereby vary the own-vehicle mark,

wherein a traveling condition is represented by manipulation of the own vehicle mark.

3. The navigation apparatus as recited in claim 1, wherein the data processor determines the driving condition using, as the vehicle data, at least one of an amount of fuel consumed and a traveled distance, fuel consumption rate data, acceleration data, a degree of depression of an accelerator pedal and a degree of braking action, a vehicle roll and pitch angle, and differential elevation data.

4. The navigation apparatus as recited in claim 3, wherein the data processor calculates a fuel consumption rate from the vehicle data, to determine a condition of an energy-saving driving of the vehicle from the fuel consumption rate.

5. The navigation apparatus as recited in claim 1, further comprising a data entering unit;

and a vehicle database that records a history of the vehicle data, wherein, if the own-vehicle mark is selected using the data entering unit, the data processor reads the history of the vehicle data from the vehicle database, and then displays, as the travel information, on the display unit the history of the vehicle data or a cost amount converted from a fuel consumption rate calculated from the history thereof, the history and the cost amount corresponding to a traveled time or a traveled distance.

6. The navigation apparatus as recited in claim 5, further comprising a history database that records the history of the vehicle data, wherein, if the travel information is selected using the data entering unit, the data processor calculates from the history database a past own-vehicle location that corresponds to a selected portion of the travel information, to acquire map data of the past own-vehicle location from the map database and then display the map data thereof onto the display unit.
