In step 18, a call is made from the vehicle-side telephone 4 to the receiving telephone 14 on the information center side. This call is made continuously or intermittently for a predetermined time.

The telephone control unit 15 on the information center side checks in step 4 whether or not there is an incoming call from the vehicle-side telephone 4 to the receiving telephone 14, and proceeds to step 5 if there is an incoming call. At this time, no incoming call is made in response to the incoming call.
In step 5, the caller number is input from the receiving telephone set 14, and the process proceeds to step 6, where the telephone number stored in the RAM 15c is compared with the caller number when calling the vehicle side telephone set 4. If the caller number matches the storage number of the calling time in step 7, it is determined that the remote operation in the vehicle of the operation request destination has been completed, and the process proceeds to step 8.

When the completion of the remote operation is confirmed, the completion of the operation is reported to the user who has requested the remote operation in step 8. This operation completion report may be made manually via an operator of the information center or automatically.

When there is no incoming call from the vehicle to complete the operation, the information center may repeat the above-mentioned remote operation request call to the vehicle a plurality of times at predetermined time intervals.

In this embodiment, a dedicated telephone 1 for receiving an operation completion report from the vehicle at the information center is provided.
4, the operation completion report may be received from the vehicle by the telephone that has actually made the call out of the telephones 11 to 13 that call the vehicle for remote control. .
