- step S1335 if it is determined that there is not a “stepped-over” point, that is, a point “unstepped” remains (NO in step S1335), the point of variable P is the starting point, A section whose end point is one of them is selected from the combinations for which the entire route has not been calculated (step S1336), and the process returns to step S1333.
- step S1335 determines whether all have been “taken over” (YES in step S1335). If it is determined in step S1335 that all have been “taken over” (YES in step S1335), a section starting from the point of variable P and ending at the new destination is selected (step S1337).
- step S1338) all the selected sections are connected in order to construct the entire route, and the sum of each selected section is set as the cost of the constructed entire route.
- step S1339 it is determined whether or not the entire route has been calculated based on the combination of all sections. If it is determined that the calculation has been completed, the process ends (YES in step S1339) and has not been calculated. (NO in step S1339), the process returns to step S1331.

- the current position specifying unit 84 current position specifying means
- a route calculation unit 85 (route calculation unit) that calculates a route
- an output unit 83 output unit that outputs the optimum route calculated by the route calculation unit 85 to an external terminal.
- a control unit 88 which controls the overall operation of the components of the server device 8.
- the server device 8 is connected to a communication device 9 for transmitting information transmitted from the output unit 83 to an external terminal.
- Each component of the server device 8 realizes each function by reading and writing necessary information to and from the RAM 87.
- Information received by the terminal information receiving unit 82 includes a vehicle speed sensor that measures the moving speed of the terminal connected to an external terminal, a GPS receiving antenna that receives a signal from a GPS satellite, and the direction of the external terminal. Information (sensor information) from the angular velocity sensor that measures the change is included. In addition, the search condition input to the external terminal by the user's operation and the waypoint status (whether it is a mandatory transit point or a non-essential transit point) are also included. That is, the terminal information receiving unit 82 (terminal information receiving means) determines whether the transit point is a mandatory transit point that is a transit point that requires a stop, or a transit point that does not require a stop. Receives information (predetermined point information) that specifies whether it is the ground.
- the current position specifying unit 84 specifies the current position of the external terminal based on the information from the vehicle speed sensor, the angular velocity sensor, and the GPS receiving antenna obtained by the terminal information receiving unit 82, and the map stored in the HDD 81. Based on the information, the most likely position on the map where an external terminal exists is calculated.
- the map information stored in the HDD 81 is expressed in a graph structure in which intersections are nodes and roads between intersections are links.
- information such as cost information necessary for passing through a road corresponding to the link, link travel distance, and whether it is a toll road is set for each link.
- the route calculation unit 85 uses the cost information set for each link included in the map information, and calculates a route with the minimum accumulated cost as an optimal route by a known search method (for example, Dijkstra method).
- the route calculation unit 116 selects a condition received by the terminal information receiving unit 82 from a plurality of predetermined search conditions prepared in advance, and based on the selected search condition
- the cost of each link can be adjusted. For example, when three search conditions such as “recommended mode”, “paid road avoidance mode”, and “distance priority mode” are prepared and “recommended mode” is selected, only cost information set for the link is displayed. To calculate the optimal route.
- cost information for a link for which a toll road is set is predetermined based on information indicating whether the toll road is set for the link.
- the optimal route is calculated by adding the penalty cost.
- “distance priority mode” an optimal route is calculated based on the travel distance of the link instead of the cost information.
- the selected search condition can be applied to the entire route or can be applied to each section.
- the route calculation unit 85 determines a predetermined value for the section of the current route when the section included in the current route (existing route) is also included in the new route at the time of recalculation of the new route. Is applied to the section of the new route, and when a section included in the current route is not included in the new route, a predetermined calculation condition determined in advance is applied to the section of the new route.
- the route calculation unit 85 re-calculates a new route by newly receiving information on a predetermined point while the current route (existing route) to the destination (existing destination) has already been calculated. In this case, the predetermined condition set when calculating the current route is also applied when recalculating the new route.
- a traveling order fixing unit 86 (a traveling order fixing unit) that fixes the absolute traveling order of a predetermined waypoint or destination among the destinations and waypoints (existing waypoints) in the current route is provided.
- the calculation unit 85 applies the cyclic order fixed by the cyclic order fixing unit 86 to the recalculation of the new route with the predetermined condition as a predetermined condition. Further, the route calculation unit 85 does not use the non-essential transit point based on the information received by the terminal information receiving unit 82 when recalculating the new route.
- the server device 8 may include a cyclic relative order fixing unit (not shown) instead of the cyclic order fixing unit 86.
- the cyclic order is fixed to fix the relative order of the given waypoints and destinations.
- the route calculation section applies the cyclic order fixed by the cyclic relative order fixing section to the recalculation of the new path as a predetermined condition.
- the server device when a new point (new destination or waypoint) is added after the route to the destination is set by the external terminal, the current route If the user has the intention to specify the order of circulation for a part of the waypoint or destination (existing waypoint or destination), the server device optimizes the route after reflecting that intention. can do. Further, when calculating a new route, the search conditions set by the user when calculating the current route can be taken over. That is, according to the fifth embodiment, it is possible to calculate an optimum route reflecting the user's intention.
- the server device 8 includes the current position specifying unit 84 and calculates the current position of the terminal based on various sensor information received from the external terminal.
- the current position is specified by the terminal itself, and the terminal information receiving unit 82 of the server apparatus 8 receives the information on the current position calculated by the terminal itself, and the server apparatus 8 only performs route calculation.
- the server device receives a terminal information receiving unit (terminal information) that receives information about the terminal including information on the current position of the external terminal and information on a predetermined point including the destination and waypoint set by the terminal.
- Receiving means a route calculating part (route calculating means) for calculating a route from the current position received by the terminal information receiving part to a predetermined point, and outputting the route calculated by the route calculating part to the terminal
- An output unit output means
- the route calculation unit is a state where a current route (existing route) to a destination (existing destination) has already been calculated, and a new predetermined point (destination or destination)
- the predetermined condition set when the current route is calculated may be applied also when the new route is recalculated.
