After the parking target information is transmitted to the mobile terminal 400 of the member by the processing as described above, the monitoring unit 190 of the present invention determines whether or not a vehicle is parked in the corresponding parking sector, and the parking target information of the parked vehicle. Whether or not the vehicle has been transmitted is monitored using the state information generated by the state information generating unit 120 (S640, S650).

When it is confirmed that the vehicle is parked in the corresponding parking sector (S640) and the parked vehicle is the corresponding vehicle to which the parking target information is guided, the intended purpose has been achieved, so the subsequent processing may not need to proceed any further.

However, when it is confirmed that the parked vehicle is parked in a vehicle other than the corresponding vehicle to which the parking target information is guided (S650), the main controller 140 of the present invention performs the second parking using the lower priority street information or the lower priority preferred parking information. Target information is generated (S660).

When the second parking target information is generated in this way, the information sharing unit 180 of the present invention transmits the second parking target information to the mobile terminal 400 of the corresponding member, and the transmitted second parking target information is the mobile terminal. In 400, it is expressed in a predetermined GUI environment, etc. (S680).

As such, the present invention monitors whether the vehicle to which the nth (n is a natural number greater than or equal to 1) parking target information actually arrives to the intended destination parking sector, and before the guided vehicle actually arrives at the location, other vehicles When the parking sector corresponding to the target location is changed to a sector in which parking is not possible by This can further enhance the completeness of the service that provides parking-related information.
