VEHICLE NAVIGATION DEVICE, A METHOD FOR NAVIGATING AND A NON-TRANSITORY COMPUTER READABLE MEDIUM

摘要

A vehicle navigation device for use on a vehicle includes a user interface that receives information on a first place and a destination, a GPS sensor that detects a position of the vehicle navigation device, and a memory that stores navigation rules information. The vehicle navigation device also includes circuitry that calculate a plurality of routes from the position of the vehicle to the destination, extracts different navigation rules, which are different from navigation rules of the first place, from navigation rules in the routes, categorizes the different navigation rules into at least two groups of first rules and second rules, determines a route from the plurality of routes, and controls the user interface to output information on the first rules before the vehicle starts driving, output navigation information on the route, and output information on the second rules when the vehicle is where the second rule is applicable.

主权项

1. A vehicle navigation device comprising:
a user interface that receives information on a first place and information on a destination; a GPS sensor that detects a position of the vehicle navigation device; a memory that stores navigation rules information; and circuitry configured to:
calculate a plurality of routes from the position of the vehicle to the destination;extract, from the memory, different navigation rules, which are different from navigation rules of the first place, from navigation rules of places included in the routes;categorize the different navigation rules into at least two groups of first rules and second rules, the first rules being navigation rules which are applicable regardless of location of the vehicle within the plurality of routes from the position of the vehicle to the destination, and the second rules being navigation rules which are applicable only at certain locations on the route;determine a route from the plurality of routes based on a total weight of the different traffic rules and at least one of a total estimated distance and a total estimated time from the position of the vehicle to the destination; andcontrol the user interface to display information on the first rules only before the vehicle starts driving, output navigation information on the route, and output information on the second rules in response to the vehicle being within a certain distance from a location where at least one of the second rules is applicable while the vehicle is driving, in a different way from outputting the navigation information, wherein the total weight of the different navigation rules is calculated based on the number of locations where the second rules are applicable.
