[Figure 3] FIG. 2 is a diagram showing a processing flow of a vehicle according to an embodiment of the present invention. [Figure 4] FIG. 2 is a diagram showing a processing flow of a vehicle according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0010] <Embodiment> A vehicle 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG.

[0011] <Vehicle 10 Configuration> As shown in FIG. 1, a vehicle 10 according to this embodiment includes a controller 100, a camera 200, and an alarm device 300. The detailed configuration of the controller 100 will be described later.

[0012] The camera 200 captures images of the interior of the vehicle 10 . In this embodiment, for example, when an imaging start request is input from the controller 100, the camera 200 starts imaging the interior of the vehicle 10 (for example, the camera is powered on and imaging starts). In this embodiment, at least one camera 200 is installed in the vehicle 10, and captures images of, for example, the dashboard, driver's seat, passenger seat, rear seat, and cargo compartment such as the trunk or luggage space of the vehicle 10. In this embodiment, the camera 200 is only required to acquire image information for determining whether or not there is any luggage or the like left behind in the vehicle cabin, and may therefore be configured to take additional images of, for example, the area at the feet of each seat or under the seats. In this embodiment, the camera 200 outputs captured image information to the controller 100, which will be described later. In this embodiment, for example, when a request to stop capturing images is input from the controller 100, the camera 200 stops capturing images of the interior of the vehicle 10 (for example, the camera is powered off to stop capturing images).

[0013] In this embodiment, the notification device 300 is, for example, a speaker that outputs sound to the outside of the cabin of the vehicle 10, and outputs sound information output from the controller 100, which will be described later. In this embodiment, the notification device 300 outputs a door lock sound when, for example, an occupant of the vehicle 10 performs an operation to lock the doors. In this embodiment, the notification device 300 outputs a sound to, for example, inform an occupant who has exited the vehicle 10 and locked the doors that there is something left behind in the vehicle compartment. The voice that notifies the driver that an item has been left behind in the vehicle will be described later.

[0014] <Configuration of controller 100> The controller 100 includes one or more processors and one or more memories communicatively connected to the one or more processors. As shown in FIG. 2, in this embodiment, the controller 100 includes a processor 110 and a memory 120. The configuration of the processor 110 will be described later.

[0015] The memory 120 includes a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, which are not shown. The memory 120 stores, for example, a control program and various data input from the processor 110. In this embodiment, the memory 120 stores, in advance, for example, location information of the home of the driver who owns the vehicle 10. Examples of home location information include location information of the driver's home and location information of a parking lot where the driver parks the vehicle 10 when he or she returns home.

[0016] <Configuration of the processor 110> As shown in FIG. 2, the processor 110 includes a position information acquisition unit 111, a door lock information acquisition unit 112, a door lock determination unit 113, a movement amount calculation unit 114, an image acquisition unit 115, a determination unit 116, and a control unit 117. Each unit of the processor 110 and the memory 120 input and output various types of information via the bus line BL.

[0017] The position information acquisition unit 111 acquires the position information of the current location of the vehicle 10 by receiving radio waves emitted from a satellite positioning system. In this embodiment, the location information acquisition unit 111 acquires location information of the vehicle 10 based on radio waves received from GPS (Global Positioning System) satellites, for example. In this embodiment, the position information acquisition unit 111 outputs the acquired position information to a door lock determination unit 113, a movement amount calculation unit 114, and a control unit 117, which will be described later, for example, via the bus line BL.

[0018] The door lock information acquisition unit 112 acquires information relating to the lock state of the doors of the vehicle 10. In this embodiment, the door lock information acquisition unit 112 acquires whether the doors of the vehicle 10 are unlocked or locked based on the output from a switch or the like (not shown) that detects the unlocked / locked state of the doors of the vehicle 10. In this embodiment, the door lock information acquisition unit 112 outputs the acquired information on the locked state of the doors to a door lock determination unit 113 and a control unit 117, which will be described later, via the bus line BL, for example.

[0019] In this embodiment, the door lock determination unit 113 determines whether the vehicle 10 is located at home and the doors of the vehicle 10 are locked. In this embodiment, the door lock determination unit 113 determines whether the vehicle 10 is located at home and the doors of the vehicle 10 are locked, for example, based on the location information of the vehicle 10 acquired from the location information acquisition unit 111 and information regarding the locking status of the doors of the vehicle 10 acquired from the door lock information acquisition unit 112. In this embodiment, the door lock determination unit 113 determines whether the vehicle 10 is located at home, for example, based on the location information of the vehicle 10 acquired by the location information acquisition unit 111 and the location information of the home stored in the memory 120. In this embodiment, for example, if the location of the vehicle 10 is within a predetermined distance (for example, within 100 m) from the location of the home, the door lock determination unit 113 determines that the vehicle 10 is located at the home. In this embodiment, the door lock determination unit 113 determines that the doors of the vehicle 10 are locked, for example, when the door lock state acquired from the door lock information acquisition unit 112 changes from an unlocked state to a locked state. In this embodiment, the door lock determination unit 113 determines that the vehicle 10 is located at home, and when it determines that the doors of the vehicle 10 are locked, it outputs the determination result that the doors are locked at home to the movement amount calculation unit 114 and the control unit 117 described later via the bus line BL.

[0020] The movement distance calculation unit 114 calculates the movement distance from one home to another based on the position information acquired by the position information acquisition unit 111 . In other words, the travel distance calculation unit 114 calculates, for example, the distance traveled by the vehicle 10 from when it departs from home until it returns to home. In this embodiment, the movement amount calculation unit 114 calculates, for example, the distance traveled by the vehicle 10 during the period from when the door lock determination unit 113 inputs a determination result that the doors are locked at home until the door lock determination unit 113 inputs another determination result that the doors are locked at home. In this embodiment, the movement amount calculation unit 114 outputs the calculation result to the control unit 117, which will be described later, via, for example, the bus line BL.

[0021] In this embodiment, the image acquisition unit 115 acquires image information of the interior of the vehicle captured by the camera 200, for example, at a timing instructed by the control unit 117, which will be described later. In this embodiment, when a first image acquisition request is input from the control unit 117 described later, the image acquisition unit 115 acquires image information of the interior of the vehicle captured by the camera 200 as a first image, and stores the acquired first image information in the memory 120 via the bus line BL. In this embodiment, when a second image acquisition request is input from the control unit 117 described later, the image acquisition unit 115 acquires image information of the interior of the vehicle captured by the camera 200 as a second image, and stores the acquired second image information in the memory 120 via the bus line BL. For example, when a plurality of cameras 200 are installed in the vehicle 10, the image acquisition unit 115 acquires image information of the interior of the vehicle input from all of the cameras 200 as the first image or the second image. The timing at which the image acquisition unit 115 acquires the first image and the second image will be described later.

[0022] In this embodiment, the determination unit 116 determines whether or not there is any item left behind in the vehicle compartment based on the first image and the second image stored in the memory 120, for example. In this embodiment, when a determination request is input from the control unit 117 (described later) via the bus line BL, the determination unit 116 determines whether or not there is any article left behind in the vehicle compartment. In this embodiment, the determination unit 116 performs, for example, image analysis or difference analysis of the first image and the second image to determine whether or not there is any article left behind in the vehicle compartment. In this embodiment, the determination unit 116 performs, for example, image analysis of the first image and the second image, and recognizes an object placed inside the vehicle compartment. In this embodiment, for example, if an object that cannot be recognized by image analysis of the first image is included among the objects recognized by image analysis of the second image, the determination unit 116 determines that there is an item left behind in the vehicle cabin. In this embodiment, for example, if a tissue box has been moved from the back seat to the passenger seat, the determination unit 116 can recognize the tissue box in both the image analysis of the first image and the second image, and therefore determines that there is no item left behind in the vehicle cabin. The determination unit 116 is not limited to the above-described determination method as long as it can determine whether or not there is an item left behind in the vehicle compartment based on the first image and the second image. In this embodiment, the determination unit 116 outputs the determination result to the control unit 117, which will be described later, via, for example, the bus line BL.

[0023] In this embodiment, the control unit 117 controls the overall processing of the vehicle 10 in accordance with a control program stored in the memory 120 .

[0024] When the control unit 117 determines that the location information of the vehicle 10 indicates that the vehicle 10 is at home and that the doors of the vehicle 10 are locked, the control unit 117 causes the image acquisition unit 115 to acquire a first image. In this embodiment, for example, when the control unit 117 receives a determination result from the door lock determination unit 113 that the door at home is locked, the control unit 117 outputs a request to the camera 200 to start capturing images and outputs a request to the image acquisition unit 115 to acquire the first image.

[0025] When the control unit 117 determines that the location information of the vehicle 10 indicates that the vehicle is located at home, the doors are locked, and the amount of movement acquired from the movement amount calculation unit 114 exceeds a predetermined amount of movement, the control unit 117 causes the image acquisition unit 115 to acquire a second image. In this embodiment, for example, when the control unit 117 receives a determination result from the door lock determination unit 113 that the door at home is locked, the control unit 117 determines whether the movement amount obtained from the movement amount calculation unit 114 exceeds a predetermined movement amount. In this embodiment, when the control unit 117 obtains a determination result from the door lock determination unit 113 that the door at home is locked and determines that the movement amount obtained from the movement amount calculation unit 114 exceeds a predetermined movement amount (e.g., 500 m), the control unit 117 outputs a request to obtain a second image to the image acquisition unit 115 via the bus line BL and also outputs a determination request to the determination unit 116. In this embodiment, for example, when the control unit 117 acquires a determination result from the determination unit 116, it outputs a request to the camera 200 to stop capturing images.

[0026] When the determination unit 116 determines that an item has been left behind, the control unit 117 notifies the occupants of the vehicle 10 of information that an item has been left behind. In this embodiment, the control unit 117 changes the door lock sound output from the notification device 300 based on the determination result of the determination unit 116, for example. An example of the door lock sound is an answerback sound that indicates that the operation has been accepted when an occupant performs an operation to lock the door. In this embodiment, when the control unit 117 obtains a determination result from the determination unit 116 that an item has been left behind, the control unit 117 causes the alarm device 300 to output a door lock sound 1 (for example, a buzzer sound for 3 seconds), for example. In this embodiment, when the control unit 117 obtains a determination result from the determination unit 116 that no item has been left behind, the control unit 117 causes the alarm device 300 to output a door lock sound 2 (for example, a buzzer sound for 0.3 seconds), for example.

[0027] <Processing flow of the control unit 117> The processing flow of the control unit 117 will be described with reference to FIGS.

[0028] The control unit 117 determines whether or not a determination result indicating that the door is locked at home has been acquired from the door lock determination unit 113 (step S110). When the control unit 117 determines that the determination result indicating that the door is locked at home has not been acquired from the door lock determination unit 113 ("NO" in step S110), the control unit 117 returns the process to the standby state. When the control unit 117 determines that a determination result indicating that the doors at home are locked has been acquired from the door lock determination unit 113 ("YES" in step S110), the control unit 117 moves the process to step S120.

[0029] When the control unit 117 determines that it has received a determination result from the door lock determination unit 113 that the door at home is locked ("YES" in step S110), it causes the image acquisition unit 115 to acquire a first image (step S120) and transitions the processing to step S130.

[0030] The control unit 117 determines whether or not a determination result indicating that the door is locked at home has been acquired from the door lock determination unit 113 (step S130). When the control unit 117 determines that the determination result indicating that the door is locked at home has not been acquired from the door lock determination unit 113 ("NO" in step S130), the control unit 117 returns the process to the standby state. When control unit 117 determines that a determination result indicating that the doors at home are locked has been acquired from door lock determination unit 113 ("YES" in step S130), control unit 117 moves the process to step S140.

[0031] The control unit 117 determines whether or not the movement amount acquired from the movement amount calculation unit 114 exceeds a predetermined movement amount (for example, 500 m) (step S140). If the control unit 117 determines that the movement amount acquired from the movement amount calculation unit 114 does not exceed the predetermined movement amount, the control unit 117 returns the process to step S130 and continues the process. When the control unit 117 determines that the movement amount acquired from the movement amount calculation unit 114 exceeds the predetermined movement amount ("YES" in step S140), the control unit 117 moves the process to step S150 shown in FIG.

[0032] If the control unit 117 determines that the movement amount acquired from the movement amount calculation unit 114 exceeds the predetermined movement amount ("YES" in step S140), it causes the image acquisition unit 115 to acquire a second image (step S150) and transitions the processing to step S160.

[0033] The control unit 117 outputs a determination request to the determination unit 116, and causes the determination unit 116 to determine whether or not any items have been left behind based on the first image captured in step S120 and the second image captured in step S150 (step S160), and then causes the process to proceed to step S170.

[0034] The control unit 117 determines whether or not there is any item left behind in the vehicle compartment based on the determination result obtained from the determination unit 116 (step S170). When the control unit 117 receives a determination result from the determination unit 116 indicating that an item has been left behind in the vehicle cabin ("YES" in step S170), the control unit 117 causes the alarm device 300 to output a door lock sound 1 (e.g., a buzzer sound for 3 seconds) (step S180) and terminates the processing. If the control unit 117 obtains a determination result from the determination unit 116 that there is no item left behind in the vehicle cabin ("NO" in step S170), the control unit 117 causes the alarm device 300 to output door lock sound 2 (e.g., a buzzer sound for 0.3 seconds) (step S190) and terminates the processing.

[0035] <Actions and Effects> As described above, the vehicle 10 of this embodiment is equipped with a camera 200 that captures images of the interior of the vehicle 10, a location information acquisition unit 111 that receives and acquires location information of the vehicle 10 by receiving radio waves emitted from a satellite positioning system, a door lock information acquisition unit 112 that acquires information regarding the lock status of the doors of the vehicle 10, a movement amount calculation unit 114 that calculates the amount of movement from home to home based on the location information, a determination unit 116 that determines whether or not there is an item left behind in the vehicle interior based on a first image captured by the camera 200 when the location information of the vehicle 10 indicates that the vehicle is located at home and the doors are locked, and a second image captured by the camera 200 when the location information of the vehicle 10 indicates that the vehicle is located at home and the doors are locked and the amount of movement exceeds a predetermined amount of movement, and a control unit 117 that, if the determination unit 116 determines that there is an item left behind, notifies the occupants of the vehicle 10 of the fact that there is an item left behind. For example, when the vehicle 10 is located in a parking lot at home and the doors of the vehicle 10 are locked, the vehicle 10 acquires a first image capturing the interior of the vehicle 10. For example, when the vehicle 10 is located in a parking lot at home and the doors of the vehicle 10 are locked, the amount of movement of the vehicle 10 from the last time the vehicle 10 was parked in the parking lot at home until the current time the vehicle 10 is parked in the parking lot at home is checked, and if the amount of movement exceeds a predetermined amount of movement, a second image capturing the interior of the vehicle 10 is acquired. That is, for example, if the vehicle 10 repeatedly unlocks and locks the doors to load luggage immediately before the departure of a trip, the vehicle 10 is not moving, and therefore does not acquire the second image. Therefore, the vehicle 10 does not detect, for example, luggage loaded for a trip as lost property. For example, if the doors of the vehicle 10 are locked at an inn at a travel destination, the vehicle 10 does not acquire the second image. Therefore, the vehicle 10 does not detect, for example, luggage loaded for a trip as lost property. This allows the vehicle 10 to determine with high accuracy whether any items have been left behind inside the vehicle.

[0036] In the vehicle 10 according to this embodiment, when the determining unit 116 determines that an article has been left behind in the vehicle compartment, the vehicle 10 notifies the occupants of the vehicle 10 of the fact that an article has been left behind. This allows the occupants of the vehicle 10 to prevent leaving their luggage behind.

[0037] The control unit 117 of the vehicle 10 according to this embodiment changes the door lock sound based on the determination result of the determination unit 116 to notify the occupants of the vehicle 10 that they have left something behind. In this embodiment, when the control unit 117 obtains a determination result from the determination unit 116 that an item has been left behind, the control unit 117 causes the alarm device 300 to output a door lock sound 1 (for example, a buzzer sound for 3 seconds), for example. In this embodiment, when the control unit 117 obtains a determination result from the determination unit 116 that no item has been left behind, the control unit 117 causes the alarm device 300 to output a door lock sound 2 (for example, a buzzer sound for 0.3 seconds), for example. In other words, if an item is left behind in the vehicle cabin, the vehicle 10 will output a long buzzer sound from the alarm device 300, for example, so that the occupants of the vehicle 10 can be made aware that an item has been left behind in the vehicle cabin. This allows the occupants of the vehicle 10 to determine whether they have left anything behind by the door locking sound, thereby preventing them from leaving their luggage behind.

[0038] <Variation 1> When the vehicle 10 described above determines that an item has been left behind in the vehicle cabin, it notifies the occupants of the vehicle 10 of this by making a door lock sound, but it may also be configured to notify the occupants of the vehicle 10 of the fact that an item has been left behind via a mobile device such as a smartphone carried by the occupants of the vehicle 10. When the vehicle 10 determines that there is an article left behind in the vehicle compartment, the vehicle 10 transmits, for example, information that there is an article left behind in the vehicle compartment and a second image of the article to the mobile terminal. This allows the occupant of the vehicle 10 to confirm what the detected lost item is, even if the occupant of the vehicle 10 moves to a location away from the vehicle 10.

[0039] The vehicle 10 of the present invention can be realized by recording the processing of the above-mentioned judgment unit 116 and control unit 117 on a recording medium readable by a computer system, reading the program recorded on this recording medium into memory, and executing it. The computer system here includes the OS and hardware such as peripheral devices.

[0040] If the above computer system uses a WWW (World Wide Web) system, it also includes the homepage providing environment (or display environment). The above program may be transmitted from a computer system in which the program is stored in a storage device or the like to another computer system via a transmission medium or by transmission waves in the transmission medium. The transmission medium for transmitting the above-mentioned program refers to a medium having a function for transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line.

[0041] The above program may be for realizing part of the above-mentioned functions. The above program may be a so-called differential file (differential program) that can realize the above-mentioned functions in combination with a program already recorded in the computer system.
