Navigation system, method for guidance along guide route, and route guidance program

A navigation system for a vehicle, comprising:

• an input unit configured to receive an input corresponding to a destination;
• a determining unit configured to determine if the input destination corresponding to a route includes a water-based route or a rail-based route;
• a presenting unit configured to display a selection screen which allows a user to select a departure terminal or an arrival terminal of the route, when it is determined that the input destination is a location on the route;
• a modifying unit configured to modify the input destination to be the termination of a road linked to the selected departure terminal or arrival terminal when the user selects the departure terminal or the arrival terminal, respectively;
• and
• a route guidance unit configured to search for a guide route to the modified destination, and perform guidance along the guide route, wherein
• when the navigation system in the vehicle arrives at the termination of the road or the vicinity thereof, the route guidance unit determines that the vehicle has arrived at the destination.

A navigation system for a vehicle, comprising:

• an input unit configured to receive an input corresponding to a destination;
• a determining unit configured to determine if the input destination corresponds to a route that includes a water-based route or a rail-based route;
• and
• a route guidance unit configured to search for a guide route on the basis of the input destination, and performs guidance along the guide route, wherein
• when the navigation system in the vehicle arrives at the termination of a road linked to the route when it is determined that the input destination is a location on the route, the route guidance unit determines that the vehicle has arrived at a destination and presents a reference route from the termination to the input destination.

A method for guidance along a guide route for a navigation system in a vehicle, the method comprising the steps of:

• (a) inputting a destination;
• (b) determining whether the input destination corresponds to a location on a route that includes a water-based route or a rail-based route;
• (c) modifying the input destination to a modified destination that corresponds to the termination of a road linked to the route or the vicinity of an arrival terminal or a departure terminal of the route, when it is determined that the input destination corresponds to a location on the route;
• (d) searching for a guide route to the modified destination to perform guidance;
• and
• (e) when the navigation system in the vehicle arrives at the termination or the vicinity thereof, or when the vehicle is positioned in the vicinity of the terminal, and the navigation system is turned off, it is determined that the vehicle has arrived at the destination.

A route guidance program for a navigation system configured to perform guidance along a guide route, comprising the steps of:

• inputting a destination;
• determining whether the input destination corresponds to a route that includes a water-based route or a rail-based route;
• modifying the input destination to a modified destination that corresponds to the termination of a road linked to the route or the vicinity of an arrival terminal or a departure terminal of the route, when it is determined that the input destination corresponds to a location on the route;
• searching for a guide route to the modified destination to perform guidance along the guide route;
• and
• when navigation system in the vehicle arrives at the termination or the vicinity thereof, or when the vehicle is positioned in the vicinity of the terminal and the navigation system is turned off, determining that the vehicle has arrived at the destination.
