Claims

[Scope of utility model registration request]

a storage means for storing map data; a first input means for inputting departure/destination point data; a second input means for inputting unit time cost and vehicle fuel consumption cost data; a third input means for selecting at least one of the criteria and inputting the selected criterion; and a first search for searching for the shortest route using the storage means, the first input means, the second input means, and the third input means. a second means for searching for the shortest distance route using the storage means, the first input means, the second input means and the third input means;
a search means, a comparison means for comparing the total cost calculated when the first search means searches for the route with the total cost calculated when the second search means searches the route; and the first search means and the second search. A route guidance device for a vehicle, comprising: a determining means for determining an optimal route by using means and a comparing means; and a display means for displaying the data and route of each of the means as necessary.
