Description

[Technical field]

[0001] The present disclosure relates to a vehicle security device and a vehicle security system. [Background technology]

[0002] Criminal acts may be committed against parked vehicles. Criminal acts include vehicle theft, break-ins, vandalism, etc. Patent Document 1 discloses a vehicle recording device. The vehicle recording device is a device intended to record images of criminal acts. When a moving object is detected around the vehicle by an anomaly detection sensor, the vehicle recording device starts recording with a CCD camera. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5316995 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional vehicle recording devices, even if a non-criminal pedestrian passes around the vehicle, the abnormality detection sensor detects the pedestrian and the CCD camera starts recording, resulting in the vehicle recording device recording unnecessary images.

[0005] In one aspect of the present disclosure, it is preferable to provide a vehicle security device and a vehicle security system that can suppress image recording and notification to those around the vehicle when there is little need for such recording. [Means for solving the problem]

[0006] One aspect of the present disclosure is a vehicle security device (3) including a moving object detection unit (9) configured to perform a process of detecting a moving object around a vehicle (7) using a sensor (15), a moving object judgment unit (11, 13) configured to determine whether the moving object detected by the moving object detection unit satisfies a preset response condition, a response unit (11) that performs at least one of recording an image of the moving object and notifying those around the vehicle when the moving object judgment unit determines that the moving object satisfies the response condition, and an information transmission unit (11) configured to transmit information related to the recording or the notification to a cloud.

[0007] A vehicle security device according to one aspect of the present disclosure determines whether a detected moving object meets a preset response condition. When a detected moving object meets the preset response condition, the vehicle security device performs at least one of recording an image and notifying the surroundings of the vehicle. Even if a moving object is detected, the vehicle security device according to one aspect of the present disclosure does not record an image or notify the surroundings of the vehicle if the moving object does not meet the preset response condition. Therefore, the vehicle security device according to one aspect of the present disclosure can suppress recording an image or notifying the surroundings of the vehicle when there is little need. [Brief description of the drawings]

[0008] [Figure 1] 1 is a block diagram showing a configuration of a vehicle security system. [Diagram 2] 4 is a flowchart showing a process executed by the vehicle security device. [Diagram 3] FIG. 2 is an explanatory diagram showing ranges A and B. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] First Embodiment 1. Configuration of vehicle security system 1 The configuration of the vehicle security system 1 will be described with reference to Fig. 1. The vehicle security system 1 includes a vehicle security device 3 and a cloud 5.

[0010] The vehicle security device 3 is mounted on a vehicle 7. The vehicle security device 3 is an ECU. The vehicle security device 3 includes a first control unit 9, a second control unit 11, an image processor 13, and a recording unit 14. The first control unit 9, the second control unit 11, and the image processor 13 have the function of executing "processing executed by the vehicle security device 3" described below. The first control unit 9, the second control unit 11, and the image processor 13 each have a CPU and a semiconductor memory (hereinafter, referred to as memory) such as a RAM or a ROM. The functions of the first control unit 9, the second control unit 11, and the image processor 13 are realized by the CPU executing a program stored in the memory. Furthermore, the execution of this program results in the execution of a method corresponding to the program. The recording unit 14 can record information. The first control unit 9 corresponds to a moving object detection unit and a starting unit, and the second control unit 11 corresponds to a moving object determination unit, a response unit and an information transmission unit.

[0011] The vehicle security device 3 is connected to the sensor 15, the camera 17, the communication unit 19, the headlight 21, the horn 23, and the speaker 25 so as to be capable of transmitting and receiving signals. The sensor 15, the camera 17, the communication unit 19, the headlight 21, the horn 23, and the speaker 25 are each attached to the vehicle 7.

[0012] The sensor 15 is installed, for example, in the passenger compartment of the vehicle 7. The sensor 15 is capable of detecting a moving object around the vehicle 7. The sensor 15 is, for example, a millimeter wave radar or a LiDAR. The device using the sensor 15 may be only the vehicle security device 3, or may be multiple devices including the vehicle security device 3. For example, the power consumption of the sensor 15 is less than the power consumption of the camera 17.

[0013] The camera 17 is installed, for example, in the passenger compartment of the vehicle 7. The camera 17 can capture the scenery around the vehicle 7 and generate an image. The device that uses the camera 17 may be only the vehicle security device 3, or may be multiple devices including the vehicle security device 3.

[0014] The communication unit 19 can perform wireless communication with the cloud 5. The headlight 21 can irradiate light ahead of the vehicle 7. The horn 23 and the speaker 25 can output sound around the vehicle 7. The horn 23 can output a sound louder than the speaker 25.

[0015] The cloud 5 includes a control unit 29, a communication unit 31, and a recording unit 33. The control unit 29 has a CPU and a memory such as a RAM or a ROM. The functions of the control unit 29 are realized by the CPU executing a program stored in the memory. Furthermore, the execution of this program results in the execution of a method corresponding to the program. The functions of the control unit 29 will be described later. The communication unit 31 can perform wireless communication between the communication unit 19 and a transfer destination 35. The recording unit 33 can record information. The transfer destination 35 is, for example, a mobile terminal owned by the user of the vehicle 7, a server of the police or a security company, etc.

[0016] 2. Processing Executed by Vehicle Security Device 3 The process executed by the vehicle security device 3 will be described with reference to Figs. 2 and 3. This process is executed, for example, when the vehicle 7 is parked. This process is executed, for example, when there is no occupant in the vehicle 7. When the vehicle 7 is parked, the state of the vehicle security device 3 is a sleep state. The sleep state is, for example, a state in which only the sensor 15 and the first control unit 9 are activated. Activated means, for example, that the power is on. The first control unit 9 and the sensor 15 are always activated even when the ignition power of the vehicle 7 is off, such as when the vehicle 7 is parked. Note that, if the sensor 15 has a processing circuit, the sleep state may be a state in which only the sensor 15 is activated. In step 1 of FIG. 2, the first control unit 9 monitors the surroundings of the vehicle 7 with the sensor 15. The process of monitoring the surroundings of the vehicle 7 is hereinafter referred to as a surroundings monitoring process. In the surroundings monitoring process, the first control unit 9 performs a process of detecting a moving object around the vehicle 7 using the sensor 15. A moving object is a moving target. Examples of targets include humans, animals, other vehicles, two-wheeled vehicles, bicycles, etc. The surroundings monitoring process continues, for example, until the driver gets into the vehicle 7.

[0017] In step 2, the first control unit 9 determines whether or not a moving object has been detected in range A by the surroundings monitoring process. Range A is a range that includes the vehicle 7 and the surroundings of the vehicle 7, as shown in FIG. 3. The vehicle 7 is, for example, located near the center of range A. Range A is a part of the range in which the sensor 15 can detect a moving object. If a moving object is detected in range A, the process proceeds to step 3. If a moving object is not detected in range A, the process returns to before step 1.

[0018] In step 3, the first control unit 9 starts up the second control unit 11, the image processor 13, and the camera 17. Note that the second control unit 11, the image processor 13, and the camera 17 are in a power-off state until a positive determination is made in step 2. Alternatively, the process of step 3 may be a process in which the first control unit 9 first activates the second control unit 11, and then the activated second control unit 11 activates the image processor 13 and the camera 17.

[0019] Moreover, the activated second control unit 11 starts capturing images of the surroundings of the vehicle 7 using the camera 17. The second control unit 11 records the images generated by the capturing in the recording unit 14. The capturing continues until this process ends or until a certain time has elapsed since the end of this process. Furthermore, the activated second control unit 11 performs image recognition on the image captured by the camera 17 using the image processor 13. Image recognition is a process for detecting a human being who is performing a specific behavior. The specific behavior is behavior characteristic of a human being who is likely to commit a criminal act against the vehicle 7. Criminal acts include, for example, theft of the vehicle 7, vehicle break-in, and vandalism. The specific behavior is, for example, the behavior of looking into the passenger compartment of the vehicle 7 from outside the vehicle 7.

[0020] The image recognition is, for example, image recognition using AI. The image processor 13 is provided with, for example, a trained model. The trained model is, for example, a model obtained by machine learning. The machine learning is, for example, deep learning. The image recognition is performed every time the camera 17 generates a new image. The image recognition continues until this process ends.

[0021] In step 4, the first control unit 9 determines whether or not a moving object has been detected in range B by the periphery monitoring process. Range B is a range that is included in range A and is narrower than range A, as shown in FIG. 3. Range B is a range that includes the vehicle 7 and the surroundings of the vehicle 7. The vehicle 7 is, for example, near the center of range B. Range B is part of the range in which the sensor 15 can detect a moving object. If a moving object is detected in range B, the process proceeds to step 5. If a moving object is not detected in range B, the process returns to before step 4.

[0022] In step 5, the second control unit 11 issues a first notification. The first notification is a notification to those around the vehicle 7. The first notification is a warning to people who are likely to commit a crime. The first notification is, for example, a notification that outputs a sound using the speaker 25. The content of the sound is, for example, "Crime prevention recording in progress."

[0023] In step 6, the second control unit 11 transmits the first information to the cloud 5 using the communication unit 19. The contents of the first information include, for example, an image captured by the camera 17, detection of a moving object in range B, the position of the moving object, the time when the moving object was detected, the position of the vehicle 7, and the fact that the first notification was made. Note that the first information corresponds to information related to recording or notification.

[0024] In step 7, the second control unit 11 judges whether or not the moving object detected in the range B corresponds to a "person performing a specific behavior" based on the result of the image recognition. Note that the "person performing a specific behavior" corresponds to a preset corresponding condition.

[0025] If the moving object detected in range B corresponds to a "human performing a specific behavior", this process proceeds to step 8. If the moving object detected in range B does not correspond to a "human performing a specific behavior", this process returns to before step 7.

[0026] In step 8, the second control unit 11 transmits the second information to the cloud 5 using the communication unit 19. The content of the second information includes, for example, an image captured by the camera 17, the detection of a "human performing a specific behavior" in range B, the position of the moving object, the time when the moving object was detected, the position of the vehicle 7, the fact that a second notification is scheduled to be made, etc. The second information corresponds to information related to recording or notification.

[0027] In step 9, the second control unit 11 issues a second notification. The second notification is a notification to those around the vehicle 7. The second notification is a warning to people who are likely to commit a crime. The warning is a stronger notification than the first notification, which is a warning to call attention. The second notification is, for example, a notification that outputs a voice using the horn 23 and the speaker 25. The content of the voice output by the speaker 25 is, for example, "I will notify security." The second notification may be a notification that turns on the headlights 21 in addition to or instead of the above notification. For example, the second notification is a notification that is easier for people around the vehicle 7 to recognize than the first notification.

[0028] 3. Processing performed by Cloud 5 The control unit 29 receives the first information and the second information transmitted by the vehicle security device 3 using the communication unit 31 and records it in the recording unit 33. The control unit 29 transfers the first information and the second information recorded in the recording unit 33 to the transfer destination 35 using the communication unit 31. The timing for transferring the first information and the second information can be selected appropriately. For example, the control unit 29 can transfer the first information and the second information when a transfer request is received from the transfer destination 35. The control unit 29 corresponds to an information receiving unit, an information recording unit, and an information transferring unit.

[0029] 4. Effects of the vehicle security device 3 and the vehicle security system 1 (1A) The vehicle security device 3 determines whether or not the moving object detected in range B corresponds to a "person performing a specific behavior." The vehicle security device 3 issues a second alert if the moving object detected in range B corresponds to a "person performing a specific behavior." Even if the vehicle security device 3 detects a moving object in range B, it does not issue a second alert if the moving object does not correspond to a "person performing a specific behavior." Therefore, the vehicle security device 3 can refrain from issuing a second alert when it is not necessary to issue a second alert.

[0030] (1B) The vehicle security device 3 issues a first notification when it detects a moving object in range B, and issues a second notification when the moving object detected in range B corresponds to a "person performing a specific behavior." Therefore, criminal acts against the vehicle 7 can be further suppressed compared to when the notification is issued only once.

[0031] (1C) The first and second notifications are notifications by light or sound. Light or sound is easily recognized by people around the vehicle 7. Therefore, criminal acts against the vehicle 7 can be further suppressed. (1D) When the vehicle security device 3 detects a moving object in range A, it activates the second control unit 11, the image processor 13, and the camera 17. Therefore, the power supply of the second control unit 11, the image processor 13, and the camera 17 can be turned off until a moving object is detected in range A. As a result, the power consumption of the vehicle security device 3 and the camera 17 can be reduced compared to when the power supply of the second control unit 11, the image processor 13, and the camera 17 is always turned on.

[0032] (1E) When the vehicle security device 3 detects a moving object in range A, it activates the second control unit 11, the image processor 13, and the camera 17. When the vehicle security device 3 detects a moving object in range B, it determines whether or not the moving object corresponds to a "person performing a specific behavior."

[0033] Since range A is wider than range B, the timing to start up second control unit 11, image processor 13, and camera 17 is earlier than the timing to determine whether or not the moving object corresponds to a "human performing a specific behavior." As a result, second control unit 11, image processor 13, and camera 17 can be started earlier than the timing to determine whether or not the moving object corresponds to a "human performing a specific behavior."

[0034] (1F) The vehicle security system 1 includes the vehicle security device 3, and therefore can achieve the above-mentioned effects (1A) to (1E). (1G) The vehicle security system 1 includes a cloud 5. The cloud 5 receives the first information and second information transmitted by the vehicle security device 3. The cloud 5 records the received first information and second information. The cloud 5 transfers the recorded first information and second information to a transfer destination 35. Therefore, the vehicle security system 1 can record and transfer the first information and second information. <Other embodiments> Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments and can be implemented in various modified forms.

[0035] (1) In the first embodiment, the second notification is made in step 9. In step 9, in addition to or instead of the second notification, an image captured by the camera 17 may be recorded. The recorded image may be stored in the recording unit 14 of the vehicle security device 3, or may be transmitted to the cloud 5.

[0036] The vehicle security device 3 records an image when a moving object detected in range B corresponds to a "person performing a specific behavior." Even if a moving object is detected in range B, the vehicle security device 3 does not record an image if the moving object does not correspond to a "person performing a specific behavior." Therefore, the vehicle security device 3 can suppress image recording when it is not necessary to record an image.

[0037] (2) The sensor 15 may be a sensor other than a millimeter wave radar or a LIDAR. The sensor 15 may be, for example, a radio wave sensor. (3) The “specific behavior” in step 7 may be a behavior other than “the behavior of peering into the cabin of the vehicle 7 from outside the vehicle 7.” The “specific behavior” may be appropriately selected from among behaviors characteristic of a person who is likely to commit a criminal act against the vehicle 7.

[0038] (4) The vehicle security device 3 may transmit only one of the first information and the second information to the cloud 5. (5) The vehicle security device 3 may perform only one of the first and second alerts.

[0039] (6) The first and second notifications may be notifications by means of something other than light and sound. For example, the first and second notifications may be notifications by vibration, smell, or the like. (7) The method of determining whether or not a moving object detected in range B corresponds to a "human performing a specific behavior" may be a method other than image recognition. For example, the vehicle security device 3 stores in advance an image template corresponding to a "human performing a specific behavior." If the similarity between the moving object detected in range B and the template is equal to or greater than a threshold, the vehicle security device 3 determines that the moving object detected in range B corresponds to a "human performing a specific behavior."

[0040] (8) The vehicle security device 3 and the method thereof described in the present disclosure may be realized by a dedicated computer provided by configuring a processor and a memory programmed to execute one or more functions embodied in a computer program. Alternatively, the vehicle security device 3 and the method thereof described in the present disclosure may be realized by a dedicated computer provided by configuring a processor with one or more dedicated hardware logic circuits. Alternatively, the vehicle security device 3 and the method thereof described in the present disclosure may be realized by one or more dedicated computers configured by a combination of a processor and a memory programmed to execute one or more functions and a processor configured with one or more hardware logic circuits. In addition, the computer program may be stored in a computer-readable non-transient tangible recording medium as instructions executed by a computer. The method for realizing the functions of each part included in the vehicle security device 3 does not necessarily need to include software, and all of the functions may be realized using one or more hardware.

[0041] (9) Multiple functions possessed by one component in the above embodiments may be realized by multiple components, or one function possessed by one component may be realized by multiple components. Also, multiple functions possessed by multiple components may be realized by one component, or one function realized by multiple components may be realized by one component. Also, part of the configuration of the above embodiments may be omitted. Also, at least part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments.

[0042] (10) In addition to the vehicle security device 3 described above, the present disclosure can also be realized in various forms, such as a system including the vehicle security device 3 as a component, a program for causing a computer to function as the vehicle security device 3, a non-transient physical recording medium such as a semiconductor memory on which the program is recorded, an alarm method, an image recording method, etc. [Explanation of symbols]
