The conduction switch (2) 620 has a structure that moves following the conduction switch (1) 618 after the conduction switch (2) 620 enters the conduction state. Therefore, when the elastic body 624 is contracted and a predetermined operating force is applied, the operating force exceeds the elastic force of the elastic body 624, and the conduction switch (1) 618 is turned on. At this time, the horn (1) is generated by the horn A630. In this manner, the horn A 630 and the horn B 632 generate the horn (1) and the horn (2) according to the operation force. Note that a relay circuit or the like may be provided between the circuits of the horn A630 and the horn B632 so that when the horn A630 and the power source 628 are in a conductive state, the horn B632 and the power source 628 are in an interrupted state. In this way, the horn (1) and the horn (2) can be used properly by properly using the operation force in one operation switch 642.

  The continuity switch (3) 622 is connected to the horn B632 in parallel to the continuity switch (2) 620. The conduction switch (3) 622 is controlled to either a conduction state or a cutoff state in accordance with a control signal from the control device 612.

  The human sensing device 614 detects a person around the vehicle 1000 based on a detection signal from the information acquisition device 616. For example, the information acquisition device 616 is a camera that is provided around the vehicle 1000 and acquires a surrounding image. The human sensing device 614 analyzes the image acquired by the information acquisition device 616 to determine the shape of the object. Or you may make it detect a person based on a motion. Alternatively, the information acquisition device 616 is an infrared sensor, and the human sensing device 614 may detect a person by detecting the shape or temperature distribution of the object based on a detection signal received from the information acquisition device. Well, it is not particularly limited to these.

  Sound generator 634 includes a speaker (not shown) provided in the interior of vehicle 1000. The sound generation device 634 generates a sound of a predetermined mode from the speaker in response to a control signal from the control device 612.

Then, it is characterized in that the alarm device 610 is controlled to generate an alarm.

  Hereinafter, with reference to FIG. 3, a control structure of a program executed by control device 612 of vehicle alarm device 610 according to the present embodiment will be described.

  In step (hereinafter, step is described as S) 1000, control device 612 determines whether or not the IG switch is turned on. Control device 612 determines whether or not IG switch 670 is turned on based on the ON signal of IG switch 670 received from HV-ECU 600. If IG switch 670 is turned on (YES in S1000), the process proceeds to S1100. If not (NO in S1000), the process returns to S1000.

  In S1100, control device 612 determines whether a person is detected around the vehicle. For example, control device 612 detects a person within a range that needs to call attention from vehicle 1000 to a predetermined distance. If it is determined that a person has been detected around vehicle 1000 (YES in S1100), the process proceeds to S1200. If not (NO in S1100), the process proceeds to S1300.

  At S1200, control device 612 generates an alarm. Specifically, the control device 612 generates a warning sound by controlling the conduction switch (3) 622 to be in a conduction state. The control device 612 may stop the generation of the alarm sound when a predetermined time elapses, or may stop the generation of the alarm sound when no person is detected. The method for stopping the alarm is not particularly limited.

  In S1300, control device 612 determines whether or not vehicle 1000 is traveling. For example, control device 612 determines whether vehicle 1000 is traveling based on a vehicle speed signal received from HV-ECU 600, but is not particularly limited. If it is determined that vehicle 1000 is traveling (YES in S1300), the process ends. If not (NO in S1300), the process returns to S1100.

  An operation of control device 612 of vehicle alarm device 610 according to the present embodiment based on the above-described structure and flowchart will be described.

  When vehicle 1000 stops, the driver turns on IG switch 670 and MG (2) 500 becomes operable (YES in S1000), and when a person is detected around vehicle 1000 (in S1100) YES), an alarm is generated (S1200). If vehicle 1000 does not start (NO in S1300), as long as a person is detected (YES in S1100), an alarm is generated (S1200).

  If IG switch 670 is turned on (YES in S1000) and no person is detected around vehicle 1000 (NO in S1100), no alarm is generated.
