Abstract

A route guidance device configured so as to be freely attachable and detachable with respect to an in-vehicle device includes a route acquiring part that acquires a vehicle route calculated based on vehicle map data and acquires a pedestrian route calculated based on the pedestrian map data; and a display that outputs the vehicle route and the pedestrian route acquired by the route acquiring part. The route acquiring part, when the route guidance device has been detached from the in-vehicle device, acquires a pedestrian route calculated based on a destination having been set to acquire the vehicle route before detachment, or when the route guidance device has been attached to the in-vehicle device, acquires a vehicle route calculated based on a destination having been set to acquire the pedestrian route before attachment.

Claims

1. A route guidance device that acquires a route from a departure point to a destination and provides guidance on the acquired route, the route guidance device being configured so as to be freely attachable and detachable with respect to a vehicle, comprising:

a route acquiring module for acquiring a vehicle route calculated based on vehicle map data and acquires a pedestrian route calculated based on pedestrian map data; and

a route outputting module for outputting the vehicle route and the pedestrian route acquired by the route acquiring module, wherein

the route acquiring module,

when the route guidance device has been detached from the vehicle, acquires a pedestrian route calculated based on the destination having been set to acquire the vehicle route before the detachment, or

when the route guidance device has been attached to the vehicle, acquires a vehicle route calculated based on the destination having been set to acquire the pedestrian route before the attachment.

2. The route guidance device according to claim 1, wherein:

the route acquiring module includes vehicle route acquiring module for acquiring a vehicle route and a pedestrian route acquiring module for acquiring a pedestrian route; and

the pedestrian route acquiring module, when the route guidance device has been detached from the vehicle, acquires a pedestrian route calculated based on the destination having been set by the vehicle route acquiring module before the detachment, or

the vehicle route acquiring module, when the route guidance device has been attached to the vehicle, acquires a vehicle route calculated based on the destination having been set by the pedestrian route acquiring module before the attachment.

3. The route guidance device according to claim 1, comprising:

a map data storage unit for storing the vehicle map data and the pedestrian map data; and

a communication unit for receiving at least one of the vehicle map data and the pedestrian map data from a server outside the vehicle and stores the received map data in the map data storing unit.

6. The route guidance device according to claim 2, comprising:

a map data storage unit for storing the vehicle map data and the pedestrian map data; and

a communication unit for receiving at least one of the vehicle map data and the pedestrian map data from a server outside the vehicle and stores the received map data in the map data storage unit.

4. A route guidance method of acquiring a route from a departure point to a destination and providing guidance on the acquired route, the route guidance method of providing guidance on the acquired route through a route guidance device being configured so as to be freely attachable and detachable with respect to a vehicle, comprising:

route acquiring step of acquiring a vehicle route calculated based on vehicle map data and acquiring a pedestrian route calculated based on pedestrian map data; and

route outputting step of outputting the vehicle route and the pedestrian route acquired at the route acquiring step, wherein

at the route acquiring step,

when the route guidance device has been detached from the vehicle, a pedestrian route calculated based on the destination having been set to acquire the vehicle route before the detachment is acquired, or

when the route guidance device has been attached to the vehicle, a vehicle route calculated based on the destination having been set to acquire the pedestrian route before the attachment is acquired.

5. A route guidance program contained on a non-transistory computer readable medium for causing a computer to execute the method described in claim 4.
