Become. Moreover, the probe center 3 provides the information regarding the detected parking lot with respect to another vehicle (S13), and the other vehicle which is looking for a parking lot discovers a parking space rapidly based on the provided information. It is possible to improve convenience.
In addition, when an event such as a concert or a baseball game is held in the area around the current position of the own vehicle when the ignition of the own vehicle is turned off, a parking lot where the current position can be used by other vehicles (S7), for example, it is possible to detect a parking lot that anyone can use without being limited to a specific user such as a temporary parking lot.
Furthermore, since the parking lot where the own vehicle is used or a parking lot where the frequency of use is a predetermined number of times or more is used as the parking lot used by the own vehicle, it is limited to specific users excluding the home or the monthly parking lot with a monthly contract. It becomes possible to detect a parking lot that anyone can use.

However, in the parking lot information providing system according to the second embodiment, when the destination is set by the navigation device, the current position of the host vehicle whose ignition is turned off in S8 is related to the set destination. The information is transmitted to the probe center. And the information regarding the destination set with the vehicle parked with the available parking lot information in said S13 is also delivered to the vehicle 4 together.
Thereby, in the parking lot information providing system according to the second embodiment, it is possible to provide information related to a parking lot that is optimal for parking with respect to another vehicle having the same destination set.

Note that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the scope of the present invention.
For example, in the first embodiment and the second embodiment, the navigation device 1 performs the process (S4 to S7) for detecting a parking lot that can be used by another vehicle. However, these processes are performed by the probe center 3. Anyway. However, in that case, it is necessary to transmit information about the current position coordinates when the ignition is turned off and the parking lot used by the host vehicle from the vehicle 4 to the probe center 3. Further, the processing (S4 to S7) may be performed by the navigation device 1 and the probe center 3 in a shared manner.

  Moreover, you may make it provide the information regarding the parking lot which can be utilized with the other vehicle which the navigation apparatus 1 detected to another vehicle by vehicle-to-vehicle communication, without passing through the probe center 3. FIG.

It is good also as determining also whether it is a done parking lot. And when it determines with it not being a use parking lot of the own vehicle and the parking lot memorize | stored in map information DB27, it transfers to S5. As a result, it is possible to detect a parking lot that can be used by other vehicles only for a temporary parking lot that is not stored in the map data or for a newly established parking lot.
Furthermore, you may make it update map information DB27 based on the information regarding the detected temporary parking lot or the newly established parking lot. As a result, it becomes possible to supplement the information related to the parking lot that the navigation device 1 has, and the parking lot once detected in S7 in the past is again detected as a temporary parking lot or a newly established parking lot by the same processing. This reduces the processing burden on the navigation ECU.

  Further, the size of the peripheral area for determining whether or not an event is being performed in S6 may be changed according to the type of event. For example, when targeting a large-scale event in which a shuttle bus to the event venue is operating, it is preferable to extend the peripheral area from within a radius of 1 km to within 5 km.
