[0010] Embodiments of a vehicle recording control device and a vehicle recording control method according to the present disclosure will be described in detail below with reference to the accompanying drawings. Note that the present invention is not limited by the following embodiments.

[0011] [First Embodiment] (Vehicle Recording Device) FIG. 1 is a block diagram showing a configuration example of a vehicle recording device having a vehicle recording control device according to the first embodiment. The vehicle recording device 10 is a so-called drive recorder that records video data obtained by photographing the surroundings of the vehicle.

[0012] While the engine is running from start to stop, that is, while the vehicle is operating rather than in a parked state, the vehicle recording device 10 always records video, performs so-called loop recording, and detects events.

[0013] The vehicle recording device 10 has a parking monitoring function. When the accessory power is OFF, in other words, when the vehicle is parked and the vehicle recording device 10 operates using a dedicated battery of the vehicle recording device 10 or a vehicle's always-on power supply (battery), if an event based on acceleration is detected, the vehicle recording device 10 performs video shooting and recording. In a mechanical parking lot, when the vehicle recording device 10 detects movement by the machinery of the mechanical parking lot, the recording function is restricted.

[0014] In addition to being mounted on the vehicle, the vehicle recording device 10 may be a portable device that can be used in the vehicle. Further, the vehicle recording device 10 may be realized including functions or configurations of a device pre-installed in the vehicle, a navigation device, or the like. The vehicle recording device 10 includes a camera unit (imaging unit) 210, a recording unit 220, an operation unit 230, a display unit 240, an acceleration sensor 250, a GNSS (Global Navigation Satellite System) reception unit 260, and a vehicle recording control device 100.

[0015] The camera unit 210 has a plurality of cameras that photograph the surroundings of the vehicle. The plurality of cameras photograph in different directions with respect to the vehicle. In the present embodiment, the camera unit 210 has a front camera 211 that can photograph the front and a rear camera 212 that can photograph the rear. The front camera 211 is disposed, for example, in front of the passenger compartment of the vehicle. The rear camera 212 is disposed, for example, behind the passenger compartment of the vehicle. In the following description, when it is not necessary to distinguish between the plurality of cameras, the description will be made with respect to the camera unit 210. The camera unit 210 outputs the photographed video data to the video data acquisition unit 120 of the vehicle recording control device 100. The video data is, for example, a moving image composed of images at 30 frames per second.

[0016] Although the camera unit 210 has been described as including a plurality of cameras, one camera may be used.

[0017] The recording unit 220 is used for temporarily storing data in the vehicle recording device 10. The recording unit 220 is, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a recording unit such as a memory card. Alternatively, it may be an external recording unit wirelessly connected via a communication device (not shown). The recording unit 220 records loop recording video data or stores event recording data based on a control signal output from the recording function control unit 123 of the vehicle recording control device 100.

[0018] The operation unit 230 can receive various operations on the vehicle recording device 10. For example, the operation unit 230 can receive an operation of manually storing the photographed video data as event recording data in the recording unit 220. For example, the operation unit 230 can receive an operation of playing back the loop recording video data recorded in the recording unit 220 or the saved event recording data. For example, the operation unit 230 can receive an operation of deleting the event recording data saved in the recording unit 220. For example, the operation unit 230 can receive an operation of ending the loop recording. The operation unit 230 outputs operation information to the operation control unit 125 of the vehicle recording control device 100.

[0019] The display unit 240 is, for example, a display device unique to the vehicle recording device 10, or a display device shared with another system including a navigation system. The display unit 240 may be integrally formed with the camera unit 210. The display unit 240 is a display including, for example, a liquid crystal display or an organic EL (Electro-Luminescence) display. The display unit 240 displays an image based on the video signal output from the display control unit 126 of the vehicle recording control device 100. The display unit 240 displays the image captured by the camera unit 210, or the image recorded in the recording unit 220 or the like.

[0020] The acceleration sensor 250 is a sensor that detects the acceleration generated on the vehicle. The acceleration sensor 250 outputs the detection result to the event detection unit 127 of the vehicle recording control device 100. The acceleration sensor 250 is a sensor that detects, for example, the acceleration in three axial directions. The three axial directions are the longitudinal direction, the lateral direction, and the vertical direction of the vehicle.

[0021] The GNSS receiving unit 260 is composed of a GNSS receiver that receives GNSS signals from GNSS satellites. The GNSS receiving unit 260 outputs the received GNSS signals to the position information acquisition unit 128.

[0022] (Vehicle recording control device) The vehicle recording control device 100 is an arithmetic processing device (control device) composed of, for example, a CPU (Central Processing Unit). The vehicle recording control device 100 loads the stored program into the memory and executes the instructions included in the program. The vehicle recording control device 100 controls a vehicle recording device 10 that records video data obtained by photographing the surroundings of the vehicle. The vehicle recording control device 100 includes an internal memory (not shown), and the internal memory is used for temporarily storing data in the vehicle recording control device 100. The vehicle recording control device 100 is connected to a bus 110 and includes a video data acquisition unit 120, a buffer memory 121, a video data processing unit 122, a recording function control unit 123, a playback control unit 124, an operation control unit 125, a display control unit 126, an event detection unit 127, a position information acquisition unit 128, a power state detection unit 130, and a mechanical parking lot detection unit 131.

[0023] When a mechanical parking lot is detected, the vehicle recording control device 100 includes a function control unit that controls to limit the recording function related to event detection of the vehicle recording device 10. The function control unit will be described later.

[0024] The video data acquisition unit 120 acquires video data obtained by photographing the surroundings of the vehicle. More specifically, the video data acquisition unit 120 acquires the video data output by the camera unit 210 and outputs it to the buffer memory 121.

[0025] The buffer memory 121 is an internal memory included in the vehicle recording control device 100, and is a memory that temporarily stores the video data for a certain period of time acquired by the video data acquisition unit 120 while updating it.

[0026] The video data processing unit 122 converts the video data temporarily stored in the buffer memory 121 into an arbitrary file format such as the MP4 format, encoded with an arbitrary codec such as H.264 or MPEG-4 (Moving Picture Experts Group). The video data processing unit 122 generates video data in the form of a file for a certain period of time from the video data temporarily stored in the buffer memory 121. As a specific example, the video data processing unit 122 generates video data for 60 seconds as a file from the video data temporarily stored in the buffer memory 121 in the recording order. The video data processing unit 122 outputs the generated video data to the recording function control unit 123. Also, the video data processing unit 122 outputs the generated video data to the display control unit 126. Although the period of the video data generated as a file is, for example, 60 seconds as an example, it is not limited to this.

[0027] The recording function control unit 123 performs control to cause the recording unit 220 to record the video data formed into a file by the video data processing unit 122. The recording function control unit 123 records the video data formed into a file by the video data processing unit 122 as overwritable video data in the recording unit 220 during a period when loop recording processing is executed, such as when the accessory power supply of the vehicle is ON. More specifically, the recording function control unit 123 continuously records the video data generated by the video data processing unit 122 in the recording unit 220 during a period when loop recording processing is executed, and when the capacity of the recording unit 220 is full, overwrites and records the new video data on the oldest video data.

[0028] Furthermore, the recording function control unit 123 stores, in the recording unit 220, the video data for a predetermined period in the video data generated by the video data processing unit 122 as event recording data with overwriting prohibited, when the event detection unit 127 detects an event during a period when loop recording processing is executed, such as when the accessory power supply of the vehicle is ON.

[0029] When the accessory power supply of the vehicle is OFF, in other words, when the vehicle is parked, the recording function control unit 123 operates the parking monitoring function and stores the video data captured by the camera unit 210. In the present embodiment, the parking monitoring function starts the camera unit 210 and stores the video data after detecting an event.

[0030] The event recording data that the recording function control unit 123 stores in the recording unit 220 stores, as event recording data, the video data for a predetermined period of about 10 seconds or more and 60 seconds or less before and after the time when the event is detected during the period of executing the loop recording process (constant recording process).

[0031] The event recording data that the recording function control unit 123 stores in the recording unit 220, when the accessory power supply is OFF, in other words, when starting shooting after an event is detected, stores, as event recording data, the video data for a predetermined period of about 10 seconds or more and 60 seconds or less after the event is detected and shooting is started.

[0032] The playback control unit 124 controls to play back the loop recording video data or the stored event recording data recorded in the recording unit 220 based on the playback operation control signal output from the operation control unit 125.

[0033] The operation control unit 125 acquires the operation information of the operation received by the operation unit 230. For example, the operation control unit 125 acquires the save operation information indicating the manual save operation of the video data, the playback operation information indicating the playback operation, or the delete operation information indicating the delete operation of the video data and outputs a control signal. For example, the operation control unit 125 acquires the end operation information indicating the operation to end the loop recording and outputs a control signal.

[0034] The display control unit 126 controls the display of video data on the display unit 240. The display control unit 126 outputs a video signal for causing the display unit 240 to output the video data. More specifically, the display control unit 126 outputs a video signal for displaying the video captured by the camera unit 210, or the loop recording video data recorded in the recording unit 220 or the event recording data saved, by playing back the same.

[0035] The event detection unit 127 detects an event with respect to the vehicle based on the detection result of the acceleration sensor 250. More specifically, the event detection unit 127 detects an event when an acceleration equal to or greater than a threshold value in the acceleration detected by the acceleration sensor 250 is detected. The threshold value for detecting an event during parking recording may be set to a smaller value than the threshold value for detecting an event during driving. For example, when the threshold value of the acceleration for detecting an event during driving is about 1G, the threshold value of the acceleration for detecting an event during parking recording may be set to about 0.3G.

[0036] The position information acquisition unit 128 acquires position information indicating the current position of the vehicle. The position information acquisition unit 128 calculates the current position information of the vehicle by a known method based on, for example, the GNSS signal from the GNSS reception unit 260.

[0037] The power state detection unit 130 detects the power state of the accessory power supply of the vehicle based on the information acquired from the vehicle. The power state detection unit 130 detects that the accessory power supply of the vehicle is OFF.

[0038] The mechanical parking lot detection unit 131 detects a mechanical parking lot as the location where the vehicle is positioned. In the present embodiment, the mechanical parking lot detection unit 131 detects a mechanical parking lot based on the acceleration applied to the vehicle. Specifically, when the acceleration applied to the vehicle continues in the left - right direction, front - rear direction, or up - down direction for a predetermined time, for example, about 2 seconds or more, the mechanical parking lot detection unit 131 detects the movement by the machine of the mechanical parking lot. In the present embodiment, when the acceleration applied to the vehicle continues in the rotational direction for a predetermined time or more within a plane parallel to the ground contact surface, the mechanical parking lot detection unit 131 may detect the movement by the machine of the mechanical parking lot.

[0039] In the present embodiment, the function control unit is the recording function control unit 123 that controls the storage of the video data captured by the camera unit 210 in the recording unit 220 corresponding to the event detected by the event detection unit 127.

[0040] When an event is detected by the event detection unit 127, it is detected that the accessory power is OFF by the power state detection unit 130, and the movement by the machine of the mechanical parking lot is detected by the mechanical parking lot detection unit 131, the recording function control unit 123 does not store the event recording data in the recording unit 220. In this case, the recording function control unit 123 does not perform the shooting by the camera unit 210.

[0041] When an event is detected by the event detection unit 127, it is detected that the accessory power is OFF by the power state detection unit 130, and the movement by the machine of the mechanical parking lot is not detected by the mechanical parking lot detection unit 131, the recording function control unit 123 controls to store the video data captured by the camera unit 210 in the recording unit 220 corresponding to the event detected by the event detection unit 127.

[0042] (Parking monitoring process in the vehicle recording control device) Next, with reference to FIG. 2, the flow of the parking monitoring process in the vehicle recording control device 100 will be described. Note that the description of the event detection and recording process during the operation of the vehicle will be omitted. FIG. 2 is a flowchart showing the flow of the parking monitoring process in the vehicle recording control device according to the first embodiment. In FIG. 2, the flow of the process of starting the camera and saving the video data after detecting an event will be described.

[0043] When the vehicle is in a parked state, the vehicle recording control device 100 executes the parking monitoring process of the flowchart shown in FIG. 2.

[0044] During the execution of the parking monitoring process, the vehicle recording control device 100 detects an acceleration equal to or greater than a threshold value by the acceleration sensor 250 and outputs the detection result to the event detection unit 127 of the vehicle recording control device 100.

[0045] The vehicle recording control device 100 determines whether an acceleration equal to or greater than the threshold value has been detected (step S101). More specifically, when the event detection unit 127 of the vehicle recording control device 100 detects an acceleration equal to or greater than the threshold value, the vehicle recording control device 100 determines that an event has been detected (Yes in step S101) and proceeds to step S102. When the event detection unit 127 of the vehicle recording control device 100 does not detect an acceleration equal to or greater than the threshold value, the vehicle recording control device 100 determines that no event has been detected (No in step S101) and proceeds to step S106.

[0046] When an acceleration equal to or greater than the threshold value is detected (Yes in step S101), the vehicle recording control device 100 detects that the accessory power supply of the vehicle is OFF by the power state detection unit 130 (step S102). The vehicle recording control device 100 proceeds to step S103.

[0047] When it is detected that the accessory power supply of the vehicle is OFF, the vehicle recording control device 100 determines whether the mechanical parking lot detection unit 131 has detected movement by the machine in the mechanical parking lot from the acceleration (step S103). When the vehicle recording control device 100 determines, based on the mechanical parking lot detection unit 131, that movement by the machine in the mechanical parking lot has been detected from the acceleration (Yes in step S103), it proceeds to step S106. The case of Yes in step S103 is, for example, when the vehicle is parked in a mechanical parking lot and an impact is applied to the vehicle by the operation of the machine in the mechanical parking lot. In this case, the camera unit 210 does not perform shooting. When the vehicle recording control device 100 determines, based on the mechanical parking lot detection unit 131, that movement by the machine in the mechanical parking lot has not been detected from the acceleration (No in step S103), it proceeds to step S104. The case of No in step S103 is, for example, when an impact is applied to the vehicle due to an object contacting the vehicle during parking.

[0048] The vehicle recording control device 100 causes the camera of the camera unit 210 to start shooting by the recording function control unit 123 (step S104) and proceeds to step S105.

[0049] The vehicle recording control device 100 causes the recording unit 220 to store the video data captured by the camera of the camera unit 210 as event recording data by the recording function control unit 123 (step S105) and proceeds to step S106. The event recording data stored in step S105 is the video data during the period from when shooting is started in step S104 until it is determined that a predetermined period has elapsed and shooting ends.

[0050] The vehicle recording control device 100 determines whether to end the parking monitoring function (step S106). The end of the parking monitoring function is determined, for example, by the accessory power supply being turned on or the parking monitoring function being stopped by an operation on the operation unit 230. When the vehicle recording control device 100 determines to end the parking monitoring function (Yes in step S106), it ends the processing of this flowchart. When the vehicle recording control device 100 does not determine to end the parking monitoring function (No in step S106), it executes the processing of step S101 again.

[0051] (Effect) As described above, in this embodiment, when a mechanical parking lot is detected, it is possible to control so as to limit the recording function regarding event detection of the vehicle recording device 10. According to this embodiment, in a mechanical parking lot, appropriate parking monitoring can be performed.

[0052] In this embodiment, when it is detected that the accessory power supply is OFF and movement by the machine in the mechanical parking lot is detected, it is possible not to save the video data corresponding to the event. According to this embodiment, in a mechanical parking lot, when an impact caused by the operation of the machine is detected, event recording data is not saved, so power consumption can be reduced and the parking monitoring time can be lengthened. In this embodiment, since shooting by the camera is not performed at a location where there is no problem even if vibration is detected during parking, the load on the battery can be reduced. In this embodiment, since unnecessary event recording is not performed, the capacity of the video data stored in the recording unit 220 can be reduced.

[0053] In this embodiment, when the acceleration applied to the vehicle continues in the left - right direction, front - rear direction, or up - down direction for a predetermined time or more, movement by the machine in the mechanical parking lot is detected. According to this embodiment, movement by the machine in the mechanical parking lot can be appropriately detected from the acceleration.

[0054] This embodiment can perform the above - described control without requiring a setting operation for the user to set that it is a mechanical parking lot during parking.

[0055] [Second Embodiment] With reference to FIGS. 3 and 4, the vehicle recording device 10A according to the present embodiment will be described. FIG. 3 is a block diagram showing a configuration example of a vehicle recording device having a vehicle recording control device according to the second embodiment. FIG. 4 is a flowchart showing the flow of parking monitoring processing in the vehicle recording control device according to the second embodiment. The basic configuration of the vehicle recording device 10A is the same as that of the vehicle recording device 10 in the first embodiment. In the following description, the same components as those of the vehicle recording device 10 are denoted by the same reference numerals or corresponding reference numerals, and detailed description thereof is omitted. The vehicle recording device 10A differs from the first embodiment in that it includes an acceleration setting unit 132A and a function control unit.

[0056] In this embodiment, it is suppressed that an impact due to vibration generated during the movement of the machine in the mechanical parking lot is detected as an event.

[0057] In this embodiment, the function control unit is an acceleration setting unit 132A that increases the threshold value of the acceleration detected as an event in the event detection unit 127.

[0058] When an event is detected by the event detection unit 127, the accessory power is detected as OFF by the power state detection unit 130, and the movement by the machine in the mechanical parking lot is detected by the mechanical parking lot detection unit 131, the acceleration setting unit 132A sets the threshold value of the acceleration for detecting an event in the event detection unit 127 to a second threshold value larger than a first threshold value for detecting an event during normal parking recording. For example, the second threshold value may be set to be about the same as the threshold value when event detection is performed during traveling.

[0059] Next, with reference to FIG. 4, the flow of parking monitoring processing in the vehicle recording control device 100A will be described. The processing from step S111 to step S115 and step S117 performs the same processing as steps S101 to S105 and step S106 in FIG. 2.

[0060] When the vehicle enters the parking state, the vehicle recording control device 100A executes the parking monitoring process of the flowchart shown in FIG. 4.

[0061] When it is determined that the movement by the machine in the mechanical parking lot is detected from the acceleration (Yes in step S113), the vehicle recording control device 100A increases the acceleration threshold value (step S116). More specifically, the vehicle recording control device 100A sets, by the acceleration setting unit 132A, the acceleration threshold value for detecting an event in the event detection unit 127 to a second threshold value larger than the first threshold value. The vehicle recording control device 100A proceeds to step S117.

[0062] As described above, in the present embodiment, when it is detected that the accessory power supply is OFF and the movement by the machine in the mechanical parking lot is detected, the acceleration threshold value for detecting an event is increased. Thereby, according to the present embodiment, it is possible to make it difficult to detect an event. In the present embodiment, it is possible to suppress the frequent operation of the impact detection during parking in a place where there is no problem even if vibration is detected during parking.

[0063] [Third Embodiment] The vehicle recording device 10B according to the present embodiment will be described with reference to FIGS. 5 and 6. FIG. 5 is a block diagram showing a configuration example of a vehicle recording device having a vehicle recording control device according to the third embodiment. FIG. 6 is a flowchart showing the flow of the parking monitoring process in the vehicle recording control device according to the third embodiment. The vehicle recording device 10B is different from the first embodiment in that it includes a communication unit 270B and a notification control unit 133B, and the function control unit.

[0064] In the present embodiment, when the vibration generated during the movement by the machine in the mechanical parking lot is detected as an event, unnecessary notifications are suppressed.

[0065] In the present embodiment, the function control unit is a notification control unit 133B that suppresses notifications corresponding to events detected by the event detection unit.

[0066] The communication unit 270B is a communication unit. The communication unit 270B communicates using a communication method such as Wi-Fi or a mobile phone line, and is connected to an intranet or the Internet. The communication unit 270B is controlled by the notification control unit 133B for communication. The communication unit 270B performs communication for notifying, for example, an external device such as a user's information terminal device or an insurance company's server device that an event has been detected.

[0067] When an event is detected by the event detection unit 127 and it is detected by the power state detection unit 130 that the accessory power is ON, or when an event is detected by the event detection unit 127, the accessory power is detected by the power state detection unit 130 to be OFF, and the mechanical parking lot detection unit 131 does not detect movement by the machine in the mechanical parking lot, the notification control unit 133B controls the communication unit 270B to notify an external device that an event has been detected.

[0068] When an event is detected by the event detection unit 127, it is detected by the power state detection unit 130 that the accessory power is OFF, and the mechanical parking lot detection unit 131 detects movement by the machine in the mechanical parking lot, the notification control unit 133B does not notify the external device.

[0069] Next, with reference to FIG. 6, the flow of the parking monitoring process in the vehicle recording control device 100B will be described. The processes of steps S121 to S125 and step S129 perform the same processes as steps S101 to S105 and step S106 in FIG. 2.

[0070] When the vehicle is in a parked state, the vehicle recording control device 100B executes the parking monitoring process of the flowchart shown in FIG. 6.

[0071] The vehicle recording control device 100B notifies of event detection (step S126). More specifically, the vehicle recording control device 100B controls the communication unit 270B by the notification control unit 133B to notify an external device that an event has been detected. The vehicle recording control device 100B proceeds to step S129.

[0072] When it is determined that movement by the machine in the mechanical parking lot is detected from the acceleration (Yes in step S123), the vehicle recording control device 100B causes the camera of the camera unit 210 to start shooting by the recording function control unit 123 (step S127), and proceeds to step S128.

[0073] The vehicle recording control device 100B causes the recording unit 220 to store the video data captured by the camera of the camera unit 210 as event recording data by the recording function control unit 123 (step S128), and proceeds to step S129. The event recording data stored in step S128 is the video data during the period from when shooting starts in step S127 until it is determined that a predetermined period has elapsed and shooting ends.

[0074] As described above, in this embodiment, when it is detected that the accessory power supply is OFF and movement by the machine in the mechanical parking lot is detected, notification corresponding to the event can be suppressed. In this embodiment, even when vibration is detected during parking, unnecessary notifications can be suppressed from frequently arriving due to impact detection during parking at a location where there is no problem.

[0075] [Fourth Embodiment] The vehicle recording device 10 according to this embodiment will be described with reference to FIG. 7. FIG. 7 is a flowchart showing the flow of parking monitoring processing in the vehicle recording control device according to the fourth embodiment. The vehicle recording device 10 differs from the first embodiment in the processing of the function control unit and the mechanical parking lot detection unit 131.

[0076] In this embodiment, the function control unit controls to stop the parking monitoring function. More specifically, the function control unit controls the recording function control unit 123 to stop the shooting by the camera and controls the event detection unit 127 to stop event detection. In this embodiment, the function control unit is the recording function control unit 123 and the event detection unit 127.

[0077] The mechanical parking lot detection unit 131 detects a mechanical parking lot from the video data captured by the camera unit 210. The mechanical parking lot detection unit 131 performs image recognition processing on the video data to recognize various facilities such as a pallet for loading vehicles in the mechanical parking lot, a turntable, an operation panel, a gate, a fence, and a door, and detects the mechanical parking lot. The mechanical parking lot detection unit 131 may perform image recognition processing on the video data to recognize, for example, that the road surface under the vehicle is a metal plate and a rut-like shape is formed, and detect the mechanical parking lot. The image recognition processing can use a known method and is not limited.

[0078] The mechanical parking lot detection unit 131 detects a mechanical parking lot from the video data captured before the vehicle parks in the mechanical parking lot and before the accessory power supply is turned off. The mechanical parking lot detection unit 131 detects the mechanical parking lot from the video data captured, for example, when the vehicle enters the pallet of the mechanical parking lot by the driving operation of the driver.

[0079] When the mechanical parking lot detection unit 131 detects a mechanical parking lot and the power supply state detection unit 130 detects that the accessory power supply is OFF, the recording function control unit 123 controls to stop the shooting by the camera unit 210. In this case, the recording function control unit 123 controls to resume shooting when the accessory power supply is turned on next.

[0080] When the mechanical parking lot is detected by the mechanical parking lot detector 131 and it is detected by the power state detector 130 that the accessory power supply is OFF, the event detector 127 controls to stop event detection. In this case, when the accessory power supply is turned on next, the event detector 127 controls to resume event detection.

[0081] Next, with reference to FIG. 7, the flow of the parking monitoring process in the vehicle recording control device 100 will be described. The processes of step S202 and step S204 perform the same processes as step S102 and step S106 in FIG. 2.

[0082] When the vehicle is in a parked state, the vehicle recording control device 100 executes the parking monitoring process of the flowchart shown in FIG. 7.

[0083] The vehicle recording control device 100 determines whether a mechanical parking lot is detected from the video data by the mechanical parking lot detector 131 (step S201). When the vehicle recording control device 100 determines that a mechanical parking lot is detected from the video data by the mechanical parking lot detector 131 (Yes in step S201), it proceeds to step S202. When the vehicle recording control device 100 determines that a mechanical parking lot is not detected from the video data by the mechanical parking lot detector 131 (No in step S201), it proceeds to step S204.

[0084] When it is detected that the accessory power supply of the vehicle is OFF, the vehicle recording control device 100 stops parking monitoring (step S203). More specifically, the vehicle recording control device 100 controls the recording function control unit 123 to stop the shooting by the camera unit 210. The vehicle recording control device 100 controls the event detector 127 to stop event detection. The vehicle recording control device 100 proceeds to step S204.

[0085] As described above, in the present embodiment, when a mechanical parking lot is detected by the mechanical parking lot detection unit 131 and it is detected by the power supply state detection unit 130 that the accessory power supply is OFF, event detection can be stopped. According to the present embodiment, it is possible to suppress operation in a situation where the parking monitoring function is not required.

[0086] In the present embodiment, a mechanical parking lot can be detected from the captured video data. According to the present embodiment, before parking in a mechanical parking lot, when the mechanical parking lot is detected and the accessory power supply is turned OFF, event detection can be stopped.

[0087] [Fifth Embodiment] The vehicle recording device 10 according to the present embodiment will be described with reference to FIG. 8. FIG. 8 is a flowchart showing the flow of parking monitoring processing in the vehicle recording control device according to the fifth embodiment.

[0088] In the present embodiment, the parking monitoring function detects an event and stores video data using loop recording processing.

[0089] In the present embodiment, when the accessory power supply of the vehicle recording device 10 is OFF, in other words, when the vehicle is parked, power is supplied to the vehicle recording device 10 from the vehicle battery in addition to the accessory power supply.

[0090] Next, with reference to FIG. 8, the flow of parking monitoring processing in the vehicle recording control device 100 will be described. The processes of steps S302 to S304, step S305, and step S306 perform the same processes as steps S101 to S103, step S105, and step S106 in FIG. 2.

[0091] When the vehicle is in a parked state, the vehicle recording control device 100 executes the parking monitoring processing of the flowchart shown in FIG. 8.

[0092] The vehicle recording control device 100 starts continuous recording by the camera of the camera unit 210 (step S301). More specifically, the vehicle recording control device 100 starts loop recording processing using the video data captured by the camera unit 210 by the recording function control unit 123, and starts detecting events based on the output of the acceleration sensor 250, and proceeds to step S302.

[0093] As described above, in this embodiment, even when loop recording processing is being performed, appropriate parking monitoring can be performed in the same manner as in the above embodiment. In this embodiment, when it is detected that the accessory power is OFF and movement by the machine in the mechanical parking lot is detected, the captured video data is not saved, so that video data corresponding to unnecessary events can be prevented from being saved.

[0094] [Sixth Embodiment] The vehicle recording device 10 according to this embodiment will be described with reference to FIG. 9. FIG. 9 is a flowchart showing the flow of parking monitoring processing in the vehicle recording control device according to the sixth embodiment.

[0095] When the vehicle is in a parked state, the vehicle recording control device 100 executes the parking monitoring processing of the flowchart shown in FIG. 9.

[0096] Next, the flow of the parking monitoring processing in the vehicle recording control device 100 will be described with reference to FIG. 9. The processing of steps S311 to S313, step S315, and step S316 performs the same processing as steps S301 to S303, step S305, and step S306 in FIG. 8.

[0097] When it is detected that the accessory power supply of the vehicle is OFF, the vehicle recording control device 100 determines whether a mechanical parking lot is detected from the video data by the mechanical parking lot detection unit 131 (step S314). When the vehicle recording control device 100 determines that the mechanical parking lot detection unit 131 has detected a mechanical parking lot from the video (Yes in step S314), it proceeds to step S316. When the vehicle recording control device 100 does not determine that the mechanical parking lot detection unit 131 has detected a mechanical parking lot from the video (No in step S314), it proceeds to step S315.

[0098] As described above, in the present embodiment, when performing loop recording processing, it is possible to determine whether the position where the vehicle is parked from the video is a mechanical parking lot.

[0099] The vehicle recording device according to the present disclosure may be implemented in various different forms other than the above-described embodiments.

[0100] Each component of the illustrated vehicle recording device is functionally conceptual and does not necessarily have to be physically configured as shown in the figure. That is, the specific form of each device is not limited to that shown in the figure, and all or part of it may be functionally or physically dispersed or integrated in any unit according to the processing load and usage status of each device.

[0101] The configuration of the vehicle recording device is realized, for example, as software by a program loaded into a memory or the like. In the above embodiment, it has been described as a functional block realized by the cooperation of these hardware or software. That is, these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

[0102] The above-described components include those that can be easily assumed by those skilled in the art and substantially the same ones. Furthermore, the above-described configurations can be combined as appropriate. Also, various omissions, substitutions, or changes in the configuration are possible without departing from the gist of the present invention.
