Route guidance device, route guidance method, and route guidance program

Abstract

[Problem] To provide a route guidance device, a route guidance method, and a route guidance program capable of improving route guidance optimization and user convenience when a route guidance device is mounted on or removed from an on-board device. [Solution] A route guidance device (10), configured to be freely mounted on or removed from an on-board device (1), comprises a route acquisition unit (21) which acquires a vehicle route that was found on the basis of map data for a vehicle and acquires a walking route that was found on the basis of map data for walking, and a display (13) which outputs the vehicle route and the walking route acquired with the route acquisition unit (21). When the route guidance device (10) is removed from the on-board device (1), the route acquisition unit (21) acquires a walking route found on the basis of a destination that had been set for acquisition of a vehicle route before the route guidance device (10) was removed, or when the route guidance device (10) is mounted to the on-board device (1), the route guidance device (10) acquires a vehicle route found on the basis of a destination that had been set for acquisition of a walking route before the route guidance device (10) was mounted.

Description

technical field [0001] The present invention relates to a path guidance device, a path guidance method and a path guidance program. Background technique [0002] Conventionally, a route guidance device has been proposed that searches and guides a route from a departure point to a destination, and is configured to be attachable and detachable to an in-vehicle device mounted on a vehicle. For example, Patent Document 1 discloses a navigation device including a GPS receiving unit, a display unit, a map memory unit, and the like. In the case where the navigation device is mounted on a gantry in the vehicle, the navigation device performs route guidance for the vehicle by displaying the current position on map information including facilities facing the vehicle and traffic restrictions, and then the navigation device is accessed from the When the pedestal in the car is removed, the route guidance displayed for the vehicle can be changed for the route guidance displayed for the v...

AI Technical Summary

Problems solved by technology

[0006] However, in the conventional navigation device described in Patent Document 1, when the navigation device is detached from the pedestal in the vehicle, although the map display range is changed or specific display information is deleted, there is no Search the route again, and use the search result when the navigation device is installed on the gantry in the car to guide the route directly

Therefore, by making the map data for vehicles and the map data for walking different from each other, or by making the search method for vehicles and the search method for walking different from each other, it is possible to guide a route more suitable for each purpose. , and such path guidance cannot be performed, so there is room for improvement in terms of path guidance optimization

[0007] In addition, in the conventional navigation device described in Patent Document 2, when the portable unit is detached from the vehicle-mounted unit, the portable unit cannot be detached until the preprocessing is completed, so the user cannot immediately remove the portable unit after parking the vehicle. There is room for improvement in terms of user convenience by detaching the unit from the vehicle-mounted unit and getting off the vehicle
