The recording device 1 is not limited to the electric vehicle, and may be mounted on a bicycle or a motorcycle having two tires as long as it has a battery for driving.

The imaging unit 10 is a camera used in a vehicle equipped with a recording device 1, and photographs an arbitrary range inside and outside the vehicle interior of the vehicle. The imaging unit 10 may be, for example, a camera that photographs the front of the vehicle, a camera that captures the rear of the vehicle, a camera that captures the side of the vehicle, or a combination thereof, and photographs the surroundings of the vehicle. It may be a camera unit including a plurality of cameras or an all-sky camera. It may also include a camera that photographs the interior of the vehicle. The imaging unit 10 outputs the photographing data photographed by the camera used in the vehicle to the photographing data acquisition unit 120.

The recording unit 20 records various data such as event recording data recorded when an event is detected. The recording unit 20 stores, for example, shooting data for a predetermined period based on the detection of an event as event recording data. The recording unit 20 records, for example, shooting data constantly shot while the vehicle is parked. The recording unit 20 can be realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory (Flash Memory), or a storage device such as a hard disk or a solid state drive. The recording unit 20 may be composed of a plurality of different memories or the like.

The communication unit 30 performs information communication with another external device via a wireless network. The communication unit 30 performs information communication with another external device, for example, under the control of the communication control unit 126. The communication unit 30 transmits the imaging data photographed by the imaging unit 10 to another external device, for example, under the control of the communication control unit 126. The other external device is a device set in advance by a user or the like. There are no particular restrictions on other external devices, such as a user's smartphone.

The operation unit 40 receives various operations on the control unit 100. The various operations include operations such as starting playback of event recorded data and starting saving of event recorded data. The operation unit 40 outputs an operation signal corresponding to the received operation to the operation control unit 127. The operation unit 40 can be realized by, for example, a physical switch or a touch panel provided on the display unit 50.

The display unit 50 displays various images. The display unit 50 displays, for example, the event recording data recorded by the recording unit 20. The display unit 50 is a display including, for example, a liquid crystal display (LCD) or an organic EL (Organic Electro-Luminescence) display.

The sensor 60 detects various information caused by the occurrence of an event for the vehicle. The sensor 60 is, for example, an acceleration sensor, which detects the acceleration applied to the vehicle. The sensor 60 is, for example, a gyro sensor, which detects information about the posture of the vehicle. The sensor 60 outputs the detection result to the sensor information acquisition unit 129.

The GPS receiving unit 70 is composed of a GPS receiving circuit, a GPS receiving antenna, and the like, and receives GPS signals. The GPS receiving unit 70 outputs the received GPS signal to the position information acquisition unit 130.

The CAN interface 80 is an interface for acquiring various vehicle information via CAN. The vehicle information includes, for example, information on the operating status of the engine, the traveling status of the vehicle, and the like.

The power supply 90 supplies electric power to the recording device 1. The power supply 90 is a dedicated battery of the recording device 1 connected to the recording device 1. The power supply 90 may be a battery that supplies power to the recording device 1 from the outside of the recording device 1 without being included in the configuration of the recording device 1. The power supply 90 is, for example, a battery provided in a vehicle on which the recording device 1 is mounted, an external battery connected to the recording device 1, or the like.

The control unit 100 includes a shooting data acquisition unit 120, a buffer memory 121, a shooting data processing unit 122, a recording control unit 123, a reproduction control unit 124, an event detection unit 125, a communication control unit 126, and operation control. It includes a unit 127, a display control unit 128, a sensor information acquisition unit 129, a position information acquisition unit 130, a vehicle information acquisition unit 131, a parking detection unit 132, and a power supply state detection unit 133. The control unit 100 can be realized by, for example, an electronic circuit including a CPU (Central Processing Unit), and a program for realizing each part of the control unit 100 is stored in an internal memory or the like included in the CPU. There is. In this case, the control unit 100 realizes the functions of each unit by expanding and executing the program stored in the internal memory or the like. In FIG. 1, each unit realized by the control unit 100 is described as being connected to each other via a bus 110 for easy understanding.

The shooting data acquisition unit 120 acquires various shooting data from the outside. The shooting data acquisition unit 120 acquires, for example, the shooting data taken by the imaging unit 10 from the imaging unit 10. The shooting data acquisition unit 120 outputs, for example, the shooting data acquired from the imaging unit 10 to the buffer memory 121 and the display control unit 128. The shooting data acquisition unit 120 may acquire the video data shot by the imaging unit 10 as shooting data, and in addition to the video data, audio data acquired by the imaging unit 10 or a microphone (not shown) arranged at another position. The shooting data including the above may be acquired.

The buffer memory 121 is an internal memory of the control unit 100 that temporarily stores the shooting data acquired by the shooting data acquisition unit 120. Specifically, the buffer memory 121 temporarily stores the shooting data for a certain period of time acquired by the shooting data acquisition unit 120 while updating it.

The shooting data processing unit 122 executes various processes on the shooting data temporarily stored in the buffer memory 121. The shooting data acquisition unit 120 converts, for example, the shooting data temporarily stored in the buffer memory 121 into an arbitrary file format such as the MP4 format. The shooting data processing unit 122 generates, for example, shooting data as a data file for a certain period of time from the shooting data temporarily stored in the buffer memory 121. Specifically, the shooting data processing unit 122 generates shooting data for 60 seconds as a data file from the shooting data temporarily stored in the buffer memory 121. The shooting data processing unit 122 outputs the generated shooting data to the recording control unit 123. Further, the shooting data processing unit 122 outputs the generated shooting data to the display control unit 128. The period of the shooting data generated as a data file is set to 60 seconds as an example, but the period is not limited to this.

The recording control unit 123 records various data in the recording unit 20. The recording control unit 123 controls, for example, the recording unit 20 to record the shooting data filed by the shooting data processing unit 122.

The recording control unit 123 changes the recording control process according to the state of the power supply available when the vehicle monitors parking. The state of the power supply is detected by the power supply state detection unit 133. Examples of the power source that can be used when monitoring the parking of the vehicle include a battery mounted on the vehicle, a dedicated battery of the recording device 1 built in or connected to the recording device 1, and the like. Specifically, the recording control unit 123 switches between the first parking record and the second parking record according to the state of the available power supply. The first parking record is a record that starts recording of shooting data when an event is detected. Therefore, in the first parking record, the shooting data for a predetermined period in which the recording is started when the event is detected is stored in the recording unit 20 as the event recording data. The second parking record is a record that constantly records the shooting data in the recording unit 20. Therefore, in the second parking record, when the event is detected, the shooting data for a predetermined period before and after the event detection is stored as the event recording data from the shooting data that is constantly recorded.

For example, when the vehicle starts parking, the recording control unit 123 switches between the first parking record and the second parking record according to the state of the power supply available while the vehicle is parked. Further, the recording control unit 123 sets the first parking record and the second parking record as the available power supply states depending on whether or not the value indicating the capacity of the power supply exceeds a predetermined threshold value (capacity threshold value). You may switch.

Specifically, when the power source used for parking monitoring is a vehicle battery, for example, if the voltage of the 12V battery is less than 11.5V, the recording control unit 123 performs the first parking recording from the start of parking. In this case, if the battery voltage is 11.5V or higher, the recording control unit 123 performs the second parking recording from the start of parking. The recording control unit 123 switches to the first parking record when the battery voltage becomes less than 11.5 V during the parking monitoring even when the second parking record is executed at the start of parking.

Further, when the recording control unit 123 is a dedicated power source for the recording device 1 used for parking monitoring, for example, if the remaining capacity of the battery is less than 80%, the first parking recording is performed from the start of parking. In this case, the recording control unit 123 performs the second parking record from the start of parking if the remaining capacity of the battery is 80% or more. Even when the second parking record is executed at the start of parking, the record control unit 123 switches to the first parking record when the remaining capacity of the battery becomes less than 80% during the parking monitoring.

The reproduction control unit 124 reproduces various data recorded in the recording unit 20. The reproduction control unit 124 reproduces, for example, the shooting data recorded as a data file in the recording unit 20. The reproduction control unit 124 reproduces, for example, the event recording data stored in the recording unit 20. The reproduction control unit 124 reproduces, for example, the event recording data of the first parking record recorded by the recording control unit 123. The reproduction control unit 124 reproduces, for example, the event recording data of the second parking record recorded by the recording control unit 123. Specifically, the reproduction control unit 124 reproduces arbitrary shooting data according to the control signal corresponding to the operation of the operation unit 40 output from the operation control unit 127.

The event detection unit 125 receives the detection result from the sensor 60. The event detection unit 125 detects an event based on the received detection result. The event detection unit 125 acquires, for example, acceleration information regarding acceleration as a detection result. In this case, the event detection unit 125 detects the event based on the acceleration information. When the event detection unit 125 detects an event, the event detection unit 125 outputs a control signal indicating information indicating that the event has been detected to the recording control unit 123. The detection of the event by the event detection unit 125 is not limited to the detection of the event based on the acceleration information, and is arbitrary. The event detection unit 125 may detect an event based on a moving object detection based on the video data acquired by the shooting data acquisition unit 120, a detection result of a proximity sensor or the like (not shown), or a combination of a plurality of sensor information.

The communication control unit 126 controls the communication unit 30 to perform information communication between the recording device 1 and another external device. The communication control unit 126 uses the communication unit 30, for example, under the control of the recording control unit 123, to transmit the photography data acquired by the imaging data acquisition unit 120 from the imaging unit 10 to another external device. The communication method between the communication control unit 126 and the other device is arbitrary, and various methods such as Wi-Fi (registered trademark) and a mobile phone line can be applied.

The operation control unit 127 receives an operation signal related to the operation received from the user or the like from the operation unit 40. The operation control unit 127 receives operation signals related to operations such as the start of reproduction of shooting data and the start of recording of shooting data. The operation control unit 127 outputs a control signal corresponding to the received operation signal to the recording control unit 123 or the reproduction control unit 124. In this case, the recording control unit 123 and the reproduction control unit 124 execute the operation according to the control signal.

The display control unit 128 displays various images on the display unit 50. Specifically, by outputting a video signal to the display control unit 128 and the display unit 50, the video is displayed on the display unit 50. The display control unit 128 displays the shooting data on the display unit 50 by outputting the video signal related to the shooting data recorded in the recording unit 20 to the display unit 50, for example.

The sensor information acquisition unit 129 acquires various detection results from the sensor 60. The sensor information acquisition unit 129 acquires the acceleration when the vehicle collides with another object such as another vehicle from the sensor 60. The sensor information acquisition unit 129 outputs the detection result from the acquired sensor 60 to the event detection unit 125.

The position information acquisition unit 130 receives a GPS signal from the GPS reception unit 70. The position information acquisition unit 130 calculates the current position information based on the GPS signal.

The vehicle information acquisition unit 131 acquires various vehicle information via the CAN from the CAN interface 80. The vehicle information acquisition unit 131 acquires, as vehicle information, information on the operation of the engine of the vehicle, information on whether or not the battery is charged, information on the operation of the electric power system of the vehicle such as the remaining capacity of the battery. The vehicle information acquisition unit 131 outputs the acquired vehicle information to the parking detection unit 132 and the recording control unit 123.

The parking detection unit 132 detects that the vehicle has parked. For example, based on the vehicle information received from the vehicle information acquisition unit 131, the parking detection unit 132 has selected the power of the vehicle engine or the like, the accessory power supply, and the parking gear. It detects conditions such as that the side brake has been activated and that the current position of the vehicle indicates a parking lot. The parking detection unit 132 may detect a combination of various conditions. The parking detection unit 132 detects that the vehicle has parked based on the detected conditions.

The power supply state detection unit 133 detects the state of the battery that drives the vehicle based on the vehicle information received from the vehicle information acquisition unit 131. The power supply state detection unit 133 acquires information on the remaining capacity of the battery from, for example, a control circuit that controls charging / discharging of the current or voltage of the battery that drives the vehicle. The power supply state detection unit 133 detects the state of the dedicated power supply 90 of the recording device 1 connected to the recording device 1. The power supply state detection unit 133 acquires information on the remaining capacity of the power supply 90 from a control circuit that controls charging / discharging of the current or voltage of the power supply 90.

First, the control unit 100 determines whether or not the vehicle is parked (step S101). If it is determined that the vehicle is parked (Yes in step S101), the control unit 100 proceeds to step S102. On the other hand, when it is determined that the vehicle is not parked (No in step S101), the control unit 100 ends the process of FIG. During the period when the process of FIG. 2 is not performed, the control unit 100 functions not as a parking monitoring mode but as a mode for detecting an event during operation of the vehicle such as while the vehicle is running. Further, the process of FIG. 2 may be started when the parking of the vehicle is detected and may be ended when the parking of the vehicle is completed.

In step S102, the control unit 100 determines whether or not the remaining capacity of the power source used by the vehicle while parked satisfies a predetermined criterion (step S102). When it is determined that the remaining capacity of the power supply satisfies the predetermined criterion (Yes in step S102), the control unit 100 proceeds to step S103. On the other hand, when it is determined that the remaining capacity of the power supply does not satisfy the predetermined standard (No in step S102), the control unit 100 proceeds to step S104. In step S102, the determination as to whether or not the remaining capacity of the power source satisfies the predetermined standard is such that the remaining capacity does not hinder the running after parking by performing the second parking record while the vehicle is parked. That is, it is determined whether or not the remaining capacity of the power supply is equal to or greater than a predetermined threshold value.

In step S103, the control unit 100 starts the second parking record (step S103). Details of the processing of the second parking record will be described later. Then, the control unit 100 proceeds to step S105.

In step S104, the control unit 100 starts the first parking record (step S104), and the details of the processing of the first parking record will be described later. Then, the control unit 100 proceeds to step S105.

In step S105, the control unit 100 determines whether or not parking is completed (step S105). Specifically, the control unit 100 determines whether parking has ended or the parking monitoring mode has ended. When it is determined that parking is not completed (No in step S105), the control unit 100 proceeds to step S102 and executes the above-mentioned process. On the other hand, when it is determined that parking is completed (Yes in step S105), the control unit 100 ends the process of FIG.

Next, the processing of the first parking record according to the first embodiment of the present invention will be described with reference to FIG. FIG. 3 is a flowchart showing an example of the flow of processing of the first parking record according to the first embodiment of the present invention.

The control unit 100 determines whether or not an event has been detected (step S202). If it is determined that the event has been detected (Yes in step S202), the control unit 100 proceeds to step S203. On the other hand, if it is determined that the event is not detected (No in step S202), the control unit 100 proceeds to step S206.

In step S203, the control unit 100 starts the operation of the imaging unit 10 (step S203). Then, the control unit 100 proceeds to step S204.

The control unit 100 determines whether or not a predetermined period has elapsed since the event was detected (step S204). When it is determined that the predetermined period has not elapsed (No in step S204), the control unit 100 repeats the process of step S204. On the other hand, if it is determined that the predetermined period has elapsed (Yes in step S204), the process proceeds to step S205.

After a predetermined period of time has elapsed from the start of recording the shooting data, the control unit 100 ends the shooting of the imaging unit 10 and saves the shooting data of the predetermined period as event recording data in the recording unit 20 (step S205). Then, the control unit 100 proceeds to step S206.

In step S206, the control unit 100 determines whether or not the first parking record has been completed (step S206). When it is determined that the first parking record is completed (Yes in step S206), the control unit 100 ends the process of FIG. On the other hand, when it is determined that the first parking record has not been completed (No in step S206), the control unit 100 proceeds to step S202 and executes the above-mentioned process.

Next, the processing of the second parking record according to the first embodiment of the present invention will be described with reference to FIG. FIG. 4 is a flowchart showing an example of the flow of processing of the second parking record according to the first embodiment of the present invention.

First, the control unit 100 starts the event detection process by the event detection unit 125, the photographing of the imaging unit 10, and the loop recording processing of the photographing data photographed by the imaging unit 10 (step S301). Then, the control unit 100 proceeds to step S302.

The control unit 100 determines whether or not an event has been detected (step S302). If it is determined that the event has been detected (Yes in step S302), the control unit 100 proceeds to step S303. On the other hand, if it is determined that the event is not detected (No in step S302), the control unit 100 proceeds to step S305.

In step S303, the control unit 100 determines whether or not a predetermined period of time has elapsed since the event was detected (step S303). If it is determined that the predetermined period has not elapsed (No in step S303), the control unit 100 repeats the process of step S303. On the other hand, if it is determined that the predetermined period has elapsed (Yes in step S303), the process proceeds to step S304.

The control unit 100 saves the shooting data for a predetermined period before and after the event detection in the recording unit (step S304). Then, the control unit 100 proceeds to step S305.

In step S305, the control unit 100 determines whether or not the second parking record has been completed (step S305). When it is determined that the second parking record is completed (Yes in step S305), the control unit 100 ends the process of FIG. On the other hand, if it is determined that the second parking record has not been completed (No in step S305), the control unit 100 proceeds to step S302 and executes the above-mentioned process.

As described above, in the present embodiment, the event recording is performed by switching between the first parking record that records the data at the time of event detection according to the state of the power supply used while the vehicle is parked and the second parking record that constantly records. Data can be saved. As a result, the present embodiment can appropriately record an image while the vehicle is parked. Specifically, if the capacity of the power supply exceeds the predetermined standard, the second parking record is executed, and if the capacity of the power supply does not meet the predetermined standard, the first parking record is executed, so that the capacity of the power supply is small. Even in this case, the event record data can be appropriately saved.

[Second Embodiment]

As shown in FIG. 5, the recording device 1A is different from the recording device 1 shown in FIG. 1 in that the control unit 100A includes the parking time estimation unit 134.

In the present embodiment, the parking detection unit 132 outputs a detection result indicating whether or not the vehicle is parked to the parking time estimation unit 134. In this case, the parking time estimation unit 134 acquires the current position information, which is the parking position information, from the position information acquisition unit 130.

The parking time estimation unit 134 refers to the parking information P based on the parking position information acquired from the position information acquisition unit 130, and acquires the estimated parking time.

In the present embodiment, the parking information P is information stored in a storage unit (not shown) of the recording device 1, an available navigation device, another server device, or the like. Specifically, the parking information P includes, for example, the tendency information of the vehicle equipped with the recording device 1 and the tendency information corresponding to the facility information.

The tendency information of the vehicle equipped with the recording device 1 includes that the current parking position is home (for example, average parking time is 8 hours or more), work place (for example, average parking time is 9 hours or more), and the like. Includes information about locations that tend to park for a relatively long time at all times. In addition, the tendency information of the vehicle equipped with the recording device 1 includes information such as a supermarket (for example, an average parking time of 20 minutes) and a convenience store (for example, an average parking time of 5 minutes) where the current parking position often goes. Contains information about locations that tend to park for a relatively short period of time.

The trend information corresponding to the facility information includes information on the facility at the parking position and the general average parking time on parking. For example, a public facility A (for example, an average parking time of 50 minutes), a shopping mall B (for example, an average parking time of 3 hours), and a convenience store C (for example, an average parking time of 6 minutes).

The recording control unit 123 switches between the first parking record and the second parking record based on the estimated parking time acquired by the parking time estimation unit 134. The recording control unit 123 switches between the first parking record and the second parking record depending on whether or not the assumed parking time exceeds a predetermined threshold value (time threshold value). The recording control unit 123 switches between the first parking record and the second parking record based on the assumed parking time acquired by the parking time estimation unit 134 in addition to the state of the power supply available when the vehicle monitors parking.

[Processing of the second embodiment]
The processing of the control unit 100A of the recording device 1A according to the second embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing an example of the processing flow of the control unit 100A.

Since steps S401 and steps S404 to S406 are the same as steps S101 and S103 to S104 shown in FIG. 2, respectively, description thereof will be omitted.

When it is determined that the vehicle is parked (Yes in step S401), the control unit 100A proceeds to step S402 and determines whether or not the current position is a parking position that tends to park for a relatively long time. (Step S402). When it is determined that the parking position tends to be parked for a relatively long time (Yes in step S402), the control unit 100A proceeds to step S405. On the other hand, if it is determined that the parking position is not a parking position that tends to park for a relatively long time (No in step S402), the control unit 100A proceeds to step S403.

In step S403, it is determined whether or not the control unit 100A and the power supply capacity satisfy a predetermined standard (step S403). When it is determined that the power supply capacity satisfies the predetermined criterion (Yes in step S403), the control unit 100A proceeds to step S404. On the other hand, when it is determined that the power supply capacity does not satisfy the predetermined standard (No in step S403), the control unit 100A proceeds to step S405.

As described above, the present embodiment can switch between the first parking record and the second parking record based on the assumed parking time. Specifically, in the present embodiment, the first parking record can be executed when it is assumed that the vehicle is parked for a relatively long time. As a result, the present embodiment can appropriately record the event recording data even when the vehicle is parked for a relatively long time.

Further, in the present embodiment, when it is assumed that the parking is performed for a relatively short time, the first parking record and the second parking record can be switched based on the power supply capacity. As a result, when parking is assumed to be performed for a short time and the power supply capacity is equal to or larger than a predetermined standard, the event record data can be appropriately saved by performing the second parking record. Further, when the parking is assumed to be for a short time and the power supply capacity does not meet the predetermined standard, the event record data can be appropriately saved by performing the first parking record.

Although the embodiments of the present invention have been described above, the embodiments are not limited by the contents of these embodiments. Further, the above-mentioned components include those that can be easily assumed by those skilled in the art, those that are substantially the same, that is, those having a so-called equal range. Furthermore, the components described above can be combined as appropriate. Further, various omissions, replacements or changes of components can be made without departing from the gist of the above-described embodiment.
