Hereinafter, the process for preventing the forgotten thing of this embodiment is demonstrated according to the flowchart of FIG.

  First, in step S10, it is detected that the door of the vehicle 1 has been released so that the user can get into the vehicle 1, and then in step S11, it is detected that the door has been opened.

  Next, in step S12, it is determined whether or not the belongings provided with Chip 3 have been brought into the passenger compartment. Specifically, the control circuit 10 determines whether or not a communication line has been established by a near field communication method such as Chip 3 and Bluetooth (registered trademark, hereinafter omitted). Note that the communication range of the near field communication is set so that the communication line is established only in the passenger compartment. Here, when the communication line between the control circuit 10 and Chip 3 is established (affirmative determination), the process proceeds to step S13. On the other hand, when the communication line between the control circuit 10 and Chip 3 cannot be established (No determination), the process proceeds to step S14. By this determination, the control circuit 10 can grasp whether or not the belongings provided with the Chip 3 such as valuables are brought into the vehicle 1. FIG. 3 shows a situation in which when the two valuables 2a and 2b are brought into the vehicle 1, the control circuit 10 and the chips 3a and 3b provided in the valuables 2a and 2b communicate with each other.

  In step S <b> 13, information specific to Chip 3 is stored in the storage unit 40. Specifically, the communication unit of Chip 3 reads out the unique information stored in the storage unit and transmits it to the control circuit 10 via the antenna 50.

Similar to step S12, this can be confirmed by checking whether or not the communication line with Chip 3 has been established. FIG. 4 shows a situation in which the valuables 2a are forgotten in the passenger compartment. Next, in step S20, when the belongings provided with Chip 3 in the vehicle interior are forgotten, the information stored in the storage device 40 is updated based on the information relating to the belongings. In the case of FIG. 4, the information stored in the storage device 40 is updated from the information related to the valuables 2a and 2b to the information related to the valuables 2a. Thereafter, in step S21, it is grasped by detecting that the user has exited the vehicle by closing the door.

  Next, in step S22, based on the processing result in step S19, it is determined whether there is something left behind in the passenger compartment. Here, when there is no forgotten thing (determination determination), it is not necessary to notify, so it is detected that the user has locked the door (step S25), and the processing according to this flowchart ends.

  On the other hand, if there is something left behind in the vehicle interior in step S22 (affirmative determination), the horn 200 is sounded and the light 300 is blinked in step S23. As a result, the user can grasp that the valuable items have been forgotten in the vehicle 1. Thereafter, in step S24, it is determined whether or not the door has been opened. This is performed in order to determine whether or not the user has returned to pick up the leftover when there is leftover in the passenger compartment. If the door is opened (affirmative determination), the process returns to step S18 again. At this time, since the information stored in the storage device 40 is only information related to the forgotten item (according to step S20), in step S18, information related to the lost item is notified by voice or screen display. In the case of FIG. 4, the fact that the valuables 2a are forgotten is notified. Thus, the user can grasp what is forgotten. Thereafter, the above-described steps S19 to S25 are performed.

  On the other hand, if it is not detected in step S24 that the door has been opened (negative determination), it is detected that the user has locked the door (step S25), and the process of this flowchart is terminated. . In this case, even though there is a leftover in the vehicle 1, the user has not returned to pick up the leftover. For example, the user may immediately return to the vehicle 1 or may go to a place where the vehicle 1 can be easily viewed.

  As described above, in the present embodiment, when a user gets on the vehicle, it is determined by wireless communication whether there is a belonging equipped with a chip having a communication function.
