Accordingly, there is no waiting time until the map information 111 is displayed on the screen display unit 3a, leading to an improvement in operability.

  By the way, for example, when the vehicle is out of the radio wave range where the radio wave from the information center 5 cannot be received, the state of the vehicle device before going out of the radio wave range is displayed on the vehicle state confirmation screen 100 instead of the final vehicle device state. .

  Therefore, when the vehicle device state information is information that has passed a predetermined time or more because the vehicle is out of the radio wave range (when a predetermined time or more has passed since the last vehicle state update time), the vehicle state confirmation screen 100 As shown in FIG. 3, it may be displayed that the state information 101 of the vehicle device is information that has passed a predetermined time or longer (for example, “the vehicle state is 10 minutes or more ago”). As a result, the user can grasp in advance that there is a possibility that the displayed state information 101 of the vehicle device and the current state information of the vehicle device do not match, and therefore can take appropriate measures.

  FIG. 4 is a flowchart showing a processing flow in a case where the state information of the vehicle device is information that has passed a predetermined time or more.

  First, the portable information terminal 3 requests the information center 5 to provide a vehicle state confirmation screen to the information center 5, or a remote operation request screen is transmitted to the information center 5 (S100).

  Next, the information center 5 determines whether or not the state information of the vehicle equipment acquired from the remote operation device 7 is information that has passed for a predetermined time (S110).

  When the information center 5 determines that the state information of the vehicle device is information that has passed a predetermined time or more, the information center 5 indicates that the state information of the vehicle device described above is information that has passed a predetermined time or more. Is transmitted to the portable information terminal 3. The portable information terminal 3 displays a vehicle state confirmation screen (FIG. 3, 100) in which information 106 indicating that the state information of the vehicle device has passed a predetermined time or more is added to the state information of the vehicle device (S120).

  On the other hand, when the information center 5 determines that the state information of the vehicle device is not information that has passed a predetermined time or more, the information center 5 transmits a vehicle state confirmation screen 100 displaying only the state information of the vehicle device and the like to the portable information terminal 3. The portable information terminal 3 displays a vehicle state confirmation screen (FIG. 2A, 100) displaying only the state information of the vehicle device (S130).

  As described above, the current position information 103 of the vehicle and the state information 101 of the vehicle equipment are displayed on the vehicle state confirmation screen 100 displayed on the portable information terminal 3 according to the present embodiment. Thereby, when the same vehicle is used by a plurality of people, the user of the portable information terminal 3 can easily grasp the vehicle position (current position of the vehicle) where the end user has stopped and the state of the vehicle device. Accordingly, the user can appropriately remotely control the vehicle device according to the current position of the vehicle and the state of the vehicle device.
