Now, the owner and the manager of the vehicle 2 input the planned position range at the scheduled time from the input device 35 before using the vehicle 2. In addition, in the following description, it is assumed that the owner of the vehicle 2 performs the input operation. First, the input device 35 is operated to bring it into a state in which the planned position range at the scheduled time can be input (a state in which the identification ID code / scheduled date / time setting screen is displayed on the display of the input device 35) (step (hereinafter referred to as “S”) ) 1). Then, it is determined whether or not the owner inputs the identification ID code and the scheduled date and time (that is, the scheduled time) by the interrupt process executed at every predetermined timing (S2). The scheduled time input here is the time when the vehicle 2 should be positioned in the scheduled position range set in the subsequent processing.

When it is determined that the identification ID code and the scheduled date and time have been input by the owner (YES in S2), the control device 36 displays the coordinate input selection screen on the display of the input device 35 and uses the longitude and latitude. The owner is made to select whether to input the planned position range by coordinates (S3). Further, the control device 36 repeats the determination of S2 when the identification ID code and the scheduled date and time are not input.
