Here, the third party indicates a police station or a security company. The notification unit 230 of the present embodiment notifies the center server 30 of the vehicle information and that the vehicle 12 is in an abnormal situation, thereby notifying the police station or the security company of the vehicle information and that the vehicle 12 is in an abnormal situation. Further, in the present embodiment, when the reception unit 200 receives an abnormality notification and the inter-vehicle distance acquired by the acquisition unit 220 is less than a predetermined threshold value D1, the notification unit 230 notifies the center server 30 of the vehicle information and that the vehicle 12 is in an abnormal situation.

[0039] Note that the predetermined threshold value D1 may be determined for each positional relationship between the vehicle 12 and the surrounding vehicles. Specifically, when the surrounding vehicle is traveling in the left or right direction with respect to the vehicle 12, the predetermined threshold value D1 may be set smaller than when the surrounding vehicle is traveling in the front or rear direction with respect to the vehicle 12. Further, the predetermined threshold value D1 may be determined according to the traveling speed of the vehicle 12 or the surrounding vehicle, or the type of the vehicle 12 or the surrounding vehicle.

[0040] Further, not limited to whether the inter-vehicle distance acquired by the acquisition unit 220 is less than a predetermined threshold value D1, when the reception unit 200 receives an abnormality notification, the notification unit 230 may notify the center server 30 of the vehicle information and that the vehicle 12 is in an abnormal situation.

[0041] In addition, when the notification unit 230 receives a plurality of abnormality notifications continuously, it notifies the center server 30 of the vehicle information and that the vehicle 12 is in an abnormal situation. When the notification unit 230 receives only one abnormality notification, it may not notify the center server 30 of the vehicle information and that the vehicle 12 is in an abnormal situation.

[0042] Further, the vehicle information may include character information displayed on an identification label such as a license plate of a surrounding vehicle, the lighting state of the headlights of a surrounding vehicle, the lighting state of the turn signals of a surrounding vehicle, and the sounding state of the horn of a surrounding vehicle.

[0043] In addition, when the inter-vehicle distance acquired by the acquisition unit 220 is less than a predetermined threshold value D1 and the reception unit 200 has not received an abnormality notification, the notification unit 230 has a function of notifying the occupant to change the lane in which the vehicle 12 is traveling. In this embodiment, the notification unit 230 performs the above notification via the monitor 25 and the speaker 26.

[0044] In addition, when the reception unit 200 receives an abnormality notification, the notification unit 230 has a function of notifying the occupant to stop the vehicle 12 after changing the lane in which the vehicle 12 is traveling or to move further away from the surrounding vehicles. When the reception unit 200 receives an abnormality notification and the inter-vehicle distance acquired by the acquisition unit 220 is less than a predetermined threshold value D1, the notification unit 230 may perform the above notification.

[0045] (Flow of Control) The flow of the notification process executed in the in-vehicle device 20 of this embodiment will be described with reference to the flowchart of FIG. 5.

[0046] In step S1 of FIG. 5, the CPU 20A determines whether it has received an abnormality notification from the occupant via the input switch 24. When the CPU 20A receives an abnormality notification from the occupant (step S1: YES), it proceeds to step S2.

[0047] In step S2, the CPU 20A outputs a signal to at least one of the door lock ECU 22A and the window ECU 22B.

[0048] In step S3, the CPU 20A issues a promotion notification. Specifically, the CPU 20A notifies the occupant, via the monitor 25 and the speaker 26, to stop the vehicle 12 after changing the lane in which the vehicle 12 is traveling or to move further away from surrounding vehicles.

[0049] In step S4, the CPU 20A obtains the inter-vehicle distance from the sensor data acquired by the sensor 28.

[0050] In step S5, the CPU 20A determines whether the inter-vehicle distance is less than a predetermined threshold value D1. When the inter-vehicle distance is less than the predetermined threshold value D1 (step S5: YES), the CPU 20A proceeds to step S6. On the other hand, when the inter-vehicle distance is greater than or equal to the predetermined threshold value D1 (step S5: NO), the CPU 20A returns to step S1.

[0051] In step S6, the CPU 20A obtains the current position of the vehicle 12 measured by the GPS device 23 and stores the current position in the storage 20D as position information.

[0052] In step S7, the CPU 20A obtains an image of the surroundings of the vehicle 12 captured by the camera 27 and stores it in the storage 20D.

[0053] In step S8, the CPU 20A notifies the center server 30 of the vehicle information including the position information and the surrounding image of the vehicle 12 stored in the storage 20D, as well as the fact that the vehicle 12 is in an abnormal situation, and then returns to step S1.

[0054] On the other hand, when returning to step S1 and the CPU 20A has not received an abnormality notification from the occupant (step S1: NO), it proceeds to step S9. In step S9, the CPU 20A obtains the inter-vehicle distance from the sensor data acquired by the sensor 28.

[0055] In step S10, the CPU 20A determines whether the inter-vehicle distance is less than a predetermined threshold value D1. When the inter-vehicle distance is less than the predetermined threshold value D1 (step S10: YES), the CPU 20A proceeds to step S11. On the other hand, when the inter-vehicle distance is greater than or equal to the predetermined threshold value D1 (step S10: NO), it returns to step S1.

[0056] In step S11, the CPU 20A notifies the occupant via the monitor 25 and the speaker 26 to change the lane in which the vehicle 12 is traveling, and then returns to step S1.
