FIG. 7 shows an exchange with the car navigation device 101 until the reservation program 5021 of the parking lot reservation server 107 receives a reservation request for the parking lot from the car navigation device 101 and performs a reservation process and then reaches the reserved parking lot. FIG.
The driver of the vehicle equipped with the car navigation device 101 designates the destination on the map displayed on the display 308 at the departure point. For example, the position of “Tokyo Tower” is designated as the destination. Then, the car navigation device 101 event processing unit 402 receives the destination designated by the user and passes it to the route search processing unit 404 (step 701).
The route search processing unit 404 searches for an optimum route to the destination = “Tokyo Tower” based on the road network information in the database 406, and displays the search result on the map displayed on the display 308.
The driver operates the operation buttons of the operation button group 307 and uses the user ID and the estimated arrival time to the destination (if the estimated arrival time can be automatically acquired by the car navigation device 101, it is used. ) And “parking type information that the vehicle can park” is set, and an event processing unit of the car navigation device 101 is operated when an operation of reserving the nearest parking lot near the destination = “Tokyo Tower” is performed. Reference numeral 402 denotes, via the communication unit 401 and the mobile phone 202, the parking reservation request information to which the route information searched by the route search processing unit 404 is added together with the user ID, the parking type information, and the estimated arrival time to the destination. (Step 702).
The parking lot type distinguishes the parking space according to the size of the vehicle such as a small car, a large car, a truck, and a bus, a parking fee, and the presence or absence of a roof.

When the parking reservation server 107 receives the reservation request information to which the user ID, the desired parking type, the estimated arrival time to the destination, etc. are added from the car navigation device 101 (step 703), the reservation is made at the estimated arrival time. A parking lot 110 around a possible destination is searched from the parking lot reservation DB 106, and if there is a reservationable parking lot of the parking type desired by the user, the reservation processing is performed and registered in the reservation DB 106 (step 704). ). Then, the name and position information of the reserved parking lot are returned to the car navigation apparatus 101 as a reservation completion notice (step 705).
When the optimal parking lot 110 does not exist at the present time, the parking lot search is repeated until just before the estimated arrival time at the destination. When an empty space is made by the estimated arrival time and a reservation is made, a reservation completion notice is returned to the car navigation device 101.
Here, when searching for the parking lot 110 from the parking lot reservation DB 106, the parking lot 110 where there is an empty vehicle space that can secure a predetermined parking time (for example, 2 hours) from the parking lot type, the vicinity of the destination, and the estimated arrival time. Search for.

Upon receiving the reservation completion notification, the event processing unit 402 of the navigation device 101 automatically resets the position of the parking lot using the reserved parking lot position information as a new destination of the route search processing unit 404 (step 706). The route search processing unit 404 re-searches the route to the new destination, the display processing unit 403 displays the route to the destination on the display 308, and the guidance guidance is started (step 707).
The car navigation apparatus 101 periodically detects the latitude and longitude of the vehicle position from the received radio wave from the GPS receiver 102, and sends the latitude and longitude information of the vehicle position and the route information of the re-search result to the parking lot reservation server 107. It is transmitted at any time (step 708).

When receiving the current position information and the route information from the car navigation device 101, the parking lot reservation server 107 determines whether the current position information is a parking lot position that is reserved and registered in the reservation DB 106 (step 709). If so, it means that the vehicle has arrived at the target parking lot, and the processing for the vehicle is terminated.
However, if the current position information is not the parking lot position that is reserved and registered in the reservation DB 106, it means that the vehicle has not yet arrived at the target parking lot. Based on the route information received from the traffic information distribution server 105, traffic information such as traffic jams on the route is acquired (step 710), and the estimated arrival time to the reserved parking lot 110 is predicted and calculated (step 711). .
The parking lot reservation server 107 compares the estimated arrival time calculated in step 711 with the estimated arrival time currently registered in the reservation DB 106, and determines whether the estimated arrival time is delayed or advanced (step 712). .
And according to the late arrival scheduled time, the empty space in the parking lot around the destination managed by the parking lot reservation server 107 is searched, and the reservation is changed to the optimum parking lot. Specifically, the parking lot currently registered in the reservation DB 106 is rewritten to a new parking lot, and the estimated arrival time at the parking lot is registered (step 713).
In this case, it may be another parking space in the same parking lot 110, but may be another parking lot 110 registered in the reservation DB 106.
When calculating the estimated arrival time, calculate the required time when traveling at the recommended speed, add the traffic time to the required time as the estimated required time, and add the estimated required time to the departure time Is calculated as the estimated arrival time. By correcting the recommended speed according to the average traveling speed detected by the vehicle speed sensor 204, the estimated arrival time reflecting the actual traveling speed can be calculated.
When the reservation is changed to another parking lot 110 in step 713, new position information (latitude and longitude) of the parking lot 110 serving as the destination is transmitted to the car navigation device 101.
On the car navigation device 101 side, the new position information is reset as the destination (step 706), and guidance to a new parking lot is performed.

  Through the above processing, the search for the optimal parking lot is repeatedly performed for all the parking lots around the destination according to the expected arrival time at the destination, and the result of the reservation change by the search is the result of the reservation change. Returned to the navigation device 101, it is surely guided to a parking lot having an empty space. During this time, the driver does not need to perform any operation for changing the parking reservation.

In the above procedure, the parking lot reservation server 107 predicts and calculates the estimated arrival time at the destination after reserving the parking lot. However, the route search processing unit 404 or the event processing unit 402 of the car navigation device 101 performs the calculation. Traffic congestion information on the optimum route is acquired, the vehicle position and the estimated arrival time to the destination are predicted, the result is transmitted to the parking lot reservation server 107 as needed, and the parking reservation server 107 receives the estimated arrival time. It is possible to make a reservation or change a reservation around a destination that can be reserved.
That is, in the car navigation device 101, if the user sets a destination, traffic information on the recommended route to the destination searched by the route search processing unit 404 is acquired, and a reservation target exists based on the traffic information. The estimated arrival time at the destination to be predicted is calculated, a request for reserving the reservation object at the estimated arrival time is transmitted to the reservation object management device, and the reservation object is reserved. Thereafter, the estimated arrival time at the reserved parking lot (destination) is continuously predicted and calculated as needed, and the calculated estimated arrival time is transmitted to the parking reservation server 107 as needed.
On the other hand, the parking lot reservation server 107 determines whether it is late with respect to the estimated arrival time based on the estimated arrival time at the destination transmitted from the car navigation device 101 as needed, and determines a reserved parking lot according to the delay. Change to another parking lot, return the position information of the reservation object after the change to the car navigation apparatus 101, and in the car navigation apparatus 101 that has received this, the position indicated by the position information after the change of the reservation object is newly set. The route search processing unit 404 is automatically reset as a destination, and a recommended route to the reservation target of the new destination is calculated and guided.
When configured in this manner, the parking lot reservation server 107 acquires the traffic jam information for each vehicle and reduces the load for calculating the estimated arrival time. Moreover, route information can be omitted from information transmitted from the car navigation device 101 to the parking lot reservation server 107.

In the above embodiment, an automobile is assumed as the moving body, but the present invention can be applied even when a person carrying the navigation device walks to the destination.
In addition, when the communication path between the parking lot reservation server 107 and the car navigation device 101 remains connected during the time-based or data-based charging method until reaching the destination, or the amount of transmitted / received data If there are many, it is expected that communication costs will increase. In response to this, the current position may be intermittently transmitted to the parking lot reservation server 107 according to the distance between the destination and the current location. That is, in a section where the distance between the destination and the current location is large, the current location is transmitted to the parking reservation server 107 at intervals of 10 minutes, for example, and if the difference between the current location and the destination is less than 2 km, for example, the current location in real time Is transmitted to the parking lot reservation server 107.
Thereby, an increase in communication costs can be suppressed.
