2. Description of the Related Art Conventionally, a system for guiding an automobile to a parking lot is disclosed in, for example, Japanese Patent Application Laid-Open No. 10-122886.
The technology described in "Provision of car parking guidance information and parking management system" is known. FIG. 33 is a schematic diagram of a conventional parking guidance system. Parking Management Center 3
The parking status management device 3205 in 200 receives information on whether there is a vacancy in the parking lots 3201a to 3201c under its control (that is, whether or not parking is possible),
We keep track of which parking lots are available. The driver of the car 3203 is the on-board parking guidance device 320 in the car.
When an instruction to search for a parking lot is issued to 6, the in-vehicle parking guidance device 3206 acquires the current position of the vehicle using a signal from a satellite 3204 or the like, and the parking management center 3200 that controls the area to which the current position belongs. Parking status management device 3
An inquiry is made to 205 regarding a parking lot that is close to the current position and has an empty space. The parking status management device 3205 specifies a parking lot that satisfies such a condition,
At 06, the specified parking lot is notified. In-vehicle parking guidance device 3
206 displays the notified parking lot. Car 320
When the third driver instructs the in-vehicle parking guidance device 3206 in the car to request a parking reservation, the in-vehicle parking guidance device 320
6 transmits a reservation request to the parking status management device 3205 and displays a route to the parking lot.

[0003] As a result, the driver of the car can park the car in a vacant parking lot near the current position, so that it takes more labor than searching for a vacant parking lot by himself. Can be reduced.

[0004]

However, in the conventional system as described above, the vehicle is guided to a vacant parking lot, but the parking position in the parking lot is
There is the inconvenience that the driver of the car has to search for himself. In addition, the driver of the car does not actually travel to the parking position to determine whether a parking position suitable for the size of the vehicle, for example, if the vehicle is a large vehicle, whether a parking position for a large vehicle is available or not. I did not know. When the inside of the parking lot is congested, traveling cannot be continued, and it takes much time and effort to park at an appropriate position.

On the other hand, in order to assist in determining a parking position in a parking lot, Japanese Patent Application Laid-Open No. Hei 5-33516, "Vehicle Guidance Device in Parking Lot", describes a method for making a vehicle enter a parking lot.

Therefore, it may not be possible to park at the parking lot. In such a case, it is troublesome to search for another parking lot. Further, when the parking lot is large, the driver may park at a parking position that is far from the place where the driver of the car is going to walk (such as a store or facility). In addition, there is a problem that it takes time to enter and exit due to the delivery of the parking ticket at the time of entry and the settlement process at the time of exit.

As described above, the conventional system has a problem that not only the convenience of the driver of the car is lost but also the efficiency of using the parking lot is impaired. The present invention has been made in view of such a problem, and an object of the present invention is to improve the convenience of a driver of a car and the efficiency of using the parking lot in guiding a car to a parking lot.
