Claims

A navigation device that guides a route from a departure point to a destination to a user, and a guidance plan generation device that generates guidance plan information used by the navigation device to present candidate route points that are candidates for the user to stop by. In the computer system,
The guidance plan generation device includes:
Storing information on the candidate route points;
Calculating a movement range of the navigation device;
Refer to the information on the route candidate point, select a route candidate point existing in the calculated movement range,
The navigation device generates determination information for determining whether to present the selected route candidate point to the user based on the current time,
Generating the guidance plan information including the route candidate points existing in the movement range and the determination information of each route candidate point;
The navigation device
Obtaining the guidance plan information generated by the guidance plan generation device;
Of the route candidate points included in the acquired guidance plan information, select a route candidate point existing within a predetermined range from the current position of the navigation device as a route candidate point that can be presented,
The determination information of the selected via candidate point that can be presented is acquired as a candidate route via presentation, via candidate point that matches the current time,
A computer system characterized by presenting a user with the obtained via-presentation candidate point and a route from the current position to the via-presentation candidate point.

The guidance plan generation device stores the type of goods or services provided at the route candidate point as information on the route candidate point,
The determination information includes the type of product or service provided at the candidate route point,
The guidance plan generation device acquires, as the presentation via candidate point, the via candidate point that matches the current time with the type of product or service contained in the determination information among the via candidate points included in the guidance plan information. The computer system according to claim 1, wherein:

When the guide plan generating device receives a request for referring to the information on the candidate route point stored in the guide plan generating device from the user, the guide plan generating device uses the information on the candidate route point that has received the request for reference. To present
The determination information includes the number of times the request for reference has been received,
2. The computer system according to claim 1, wherein the navigation device preferentially presents a route candidate point with a large number of receptions of the reference request to a user.

The guidance plan generation device includes:
Stores link information that divides roads into links that connect two intersections,
A link connected to the selected link is selected by referring to a cost indicating the time required to move the link connected to the departure place or the distance indicating the distance of the link and selecting the link with the minimum cost. The cumulative cost is calculated by adding the cost from the starting point to the selected link to the cost of the above, and the process of selecting the link that minimizes the calculated cumulative cost is repeated until the destination Run,
The computer system according to claim 1, wherein a link whose cost is referred to select a link having a minimum accumulated cost is calculated as a movement range of the navigation device.

The computer system further includes a point information providing device that provides information about a candidate route point to a user,
The point information providing device includes:
Transmitting information on the route candidate point for which provision of information is requested to the guidance plan generating device;
The guidance plan generation device includes a route candidate point existing in the calculated movement range among the route candidate points requested to provide the information transmitted from the point information providing device, and the calculated movement range. The computer system according to claim 1, wherein the guidance plan information including determination information of each via candidate point existing is generated.

The guidance plan generation device includes:
In the movement range, calculate a plurality of route candidates from the starting point to the destination,
Select a route candidate point located on the calculated route candidate route,
Generating route plan points including route candidate points located on the route candidate route, determination information of each route candidate point, and route route candidates;
The navigation device
Select a route that can be traveled from the current position among the route candidates that are included in the guidance plan information,
The determination information of the route candidate point located on the route selected as the route that can be entered from the current position, the route candidate point that matches the current time is acquired as the route candidate point for presentation,
The computer system according to claim 1, wherein a route selected as a route that can be entered from the current position and the obtained via-presentation candidate point are presented to a user.

A navigation device that guides a user from a departure point to a destination while presenting a route candidate point where the user stops, and a guidance plan generation device that generates guidance plan information used by the navigation device to guide the route In a route guidance method in a computer system comprising:
The guidance plan generation device includes:
Storing information on the candidate route points;
Calculating a movement range of the navigation device;
Refer to the information on the route candidate point, select a route candidate point existing in the calculated movement range,
The navigation device generates determination information for determining whether to present the selected route candidate point to the user based on the current time,
Generating the guidance plan information including the route candidate points existing in the movement range and the determination information of each route candidate point;
The navigation device
Obtaining the guidance plan information generated by the guidance plan generation device;
Of the route candidate points included in the acquired guidance plan information, select a route candidate point existing within a predetermined range from the current position of the navigation device as a route candidate point that can be presented,
The determination information of the selected via candidate point that can be presented is acquired as a candidate route via presentation, via candidate point that matches the current time,
A route guidance method comprising presenting the acquired candidate route for presentation and a route from the current position to the candidate point for presentation via a user.
