Description

[Technical field]

[0001] The present invention relates to a technique for reducing current consumption of a driving video recording system in a parked recording mode. [Background technology]

[0002] DVRS (Digital Video Recording System) is a product that performs the DVR (Digital Video Recording) function required in a vehicle. It is a driving video recording system that is installed in a vehicle and records videos that occur while the vehicle is parked or driving.

[0003] The driving video recording system can be installed in various vehicles such as taxis, buses, and patrol cars, and generally consists of a camera that captures the interior and exterior of the vehicle, a memory that stores the captured video, a GPS module that records and tracks the vehicle's position, and a display that allows the video to be viewed in real time.

[0004] Such a driving video recording system includes a driving recording mode that is activated when the vehicle is driving and records the situation that occurs while the vehicle is being driven, and a parking recording mode that is activated when the vehicle is parked and records the situation that occurs while the vehicle is parked.

[0005] Even when the driving video recording system enters the parking recording mode, it consumes a current of several tens to several hundreds of mA for continuous video recording, and this current causes a problem of shortening the battery life or discharging the battery.

[0006] To improve this, there is a trend to add technology to driving video recording systems that suspends all functions in parking recording mode, waits while performing only some necessary operations, and wakes up all functions when an interrupt occurs due to sensing by an event detection sensor, and records and stores video. Here, the event detection sensor uses a G-sensor for detecting external impacts and a radar sensor for detecting external objects, and the event detection sensor is built into the main unit and can be easily controlled.

[0007] Event detection sensors are built into the main body or connected via a Flexible Printed Circuit Board (FPCB) or a Board to Board Connector, so they receive power directly, detect events, and have signal lines assigned to them to transfer interrupts, making them easy to control.

[0008] Meanwhile, when an event detection sensor is built into a camera, which is physically separate from the main body, the camera receives power from the main body using the POC (Power Over Coax) or PODL (Power Over Data Line) method, which applies power to the video signal line, and this power becomes the main power source for the camera's shooting section and the event detection sensor. Here, the camera transfers video and data to the main body through a combination of the camera's serializer and the main body's deserializer (hereinafter referred to as SERDES), and for this to happen, the camera must be constantly powered on.

[0009] In addition, the event detection sensor built into the camera also transmits an object detection signal to the main unit via the SERDES. However, when the event detection sensor detects an object in the parking recording mode and transmits an interrupt to the main unit, the SERDES must be operating, which consumes a large amount of current. Summary of the Invention [Problem to be solved by the invention]

[0010] The present invention has been derived from the above-mentioned need, and aims to provide a method for minimizing current consumption in a driving video recording system including a main body and a camera incorporating a motion detection sensor that are physically separate from each other. [Means for solving the problem]

[0019] In addition, in the parking recording mode, the control unit controls the power supply unit to turn off the power supply from the first power supply unit and turn on the power supply from the second power supply unit, and the event detection sensor can operate by receiving power from the second power supply unit through the second camera connector of the camera connector and the second main body connector of the main body connector.

[0020] In addition, the power supply to the photographing unit and the image processing unit can be cut off by the first camera connector of the camera connector and the first main body connector of the main body connector, so that the photographing unit and the image processing unit do not operate.

[0021] In addition, when an event is detected by the operating event detection sensor, the event detection sensor transfers an interrupt to the control unit via the second camera connector and the second main body connector, and the control unit, having received the interrupt, can control the power supply unit to turn on the power supply from the first power supply unit.

[0022] In addition, the photographing unit and the image processing unit are supplied with power from the first power supply unit via the first camera connector of the camera connector and the first main body connector of the main body connector, and the photographing unit and the image processing unit can wake up and operate.

[0023] Furthermore, when the operations of the photographing unit and the image processing unit are completed, the control unit can control the power supply unit to turn off the power supply from the first power supply unit.

[0025] In addition, the power supply unit may include a first power supply unit and a second power supply unit, and the first power supply unit and the second power supply unit may further include a step of receiving power from a battery of a vehicle in which the traveling video recording system is installed.

[0026] In addition, the controlling step may include a step of controlling the power supply unit to turn off the power supply by the first power supply unit and turn on the power supply by the second power supply unit, and the event detection sensor may further include a step of operating by receiving power supply from the second power supply unit through a second camera connector of the camera connector and a second main body connector of the main body connector.

[0027] In addition, the photographing unit and the image processing unit may further include a step in which the power supply from the first power supply unit is cut off by a first camera connector of the camera connector and a first main body connector of the main body connector, so that the photographing unit and the image processing unit do not operate.

[0028] The method may further include a step in which, when an event is detected by the operating event detection sensor, the event detection sensor transfers an interrupt to the control unit via the second camera connector and the second body connector, and the control unit, upon receiving the interrupt, controls the power supply unit to turn on the power supply from the first power supply unit.

[0029] Meanwhile, in order to achieve the above object, a computer-readable recording medium according to an embodiment of the present invention may have a program recorded thereon for executing the method for reducing current consumption in the driving video recording system described above.

[0033] Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] 1 is a block diagram showing a driving video recording system according to an embodiment of the present invention. Referring to FIG 1, the driving video recording system 1000 is a system that is installed in a vehicle, captures videos during vehicle driving, stopping, parking, etc., and stores the captured videos, and includes a camera 100 and a main body 200.

[0035] Here, the camera 100 and the main body 200 can be physically separated from each other and constructed individually.

[0036] In the present invention, a vehicle is an example of a moving body, and the moving body of the present invention is not limited to a vehicle. The moving body of the present invention may include various objects that can move, such as a vehicle, a person, a bicycle, a ship, a train, etc. Hereinafter, for convenience of explanation, the moving body will be described as a vehicle.

[0037] In addition, in this specification, an action that triggers the operation of the driving video recording system 1000 is defined as an event. For example, the types of events may be an impact event, a motion event, a user gesture event, a user touch event, a remote control command reception event, etc. Here, the driving video recording system 1000 may include all or some of a front image capturing device that captures the front of the vehicle, a rear image capturing device that captures the rear, a side image capturing device that captures the left and right sides, an image capturing device that captures the face of the vehicle driver, and an interior image capturing device that captures the interior of the vehicle.

[0038] A vehicle infrared camera, a vehicle black box, a car dash cam or a car video recorder are other expressions of the driving video recording system 1000, and all of them may mean the same thing.

[0039] Referring to FIG. 1, a camera 100 includes a photographing unit 110, an event detection sensor 120, and a camera connector .

[0040] The photographing unit 110 can photograph a video of the surroundings of a moving body. Here, the video is a video photographed in at least one situation while the vehicle is parked, stopped, or running, and can include at least one video of the front, rear, side, and interior of the vehicle. Here, the photographing unit 110 can include an infrared camera that can monitor the face or pupils of the driver, and the control unit 220 can determine the driver's state, including whether the driver is drowsy at the wheel, by monitoring the face or pupils of the driver through the infrared camera.

[0041] The photographing unit 110 may include a lens unit, an image sensor, an image signal processor (ISP), a serializer, and the like.

[0042] The event detection sensor 120 is a sensor for detecting an event, and may include an impact event detection sensor for detecting an impact applied to the vehicle and / or a motion event detection sensor for detecting an object such as a person, a vehicle, an animal, etc. approaching the vehicle. However, without being limited thereto, the event detection sensor 120 may be a concept including a sensor for detecting various events that trigger the operation of the driving video recording system 1000.

[0043] The camera connector 130 receives power from the main body 200 and performs an interface function between the camera 100 and the main body 200, such as performing data communication.

[0044] Meanwhile, the main body 200 includes an image processor 210 , a controller 220 , a main body connector 230 and a power supply 240 .

[0045] The image processor 210 may receive and process the video captured by the camera 110 and store the video in a memory (not shown). For example, the image processor 210 may analyze the video received from the camera 100 to determine whether the driver of the vehicle needs a driving assistance function (Advanced driving assistance system: ADAS). Here, the driving assistance function may include detecting the departure of a vehicle located in front of the vehicle and informing the driver whether a Forward Vehicle Start Alarm (FVSA) is required, detecting whether a traffic light has changed and informing the driver whether a Traffic Light Change Alarm (TLCA) is required, detecting whether the vehicle has departed from its lane and informing the driver whether a Lane Departure Warning System (LDWS) is required, detecting a risk of collision with a vehicle ahead of the vehicle and informing the driver whether a Forward Collision Warning System (FCWS) is required, and the like.

[0046] The control unit 220 may control the overall operation of the driving video recording system 1000. Specifically, the control unit 220 may set a recording mode of the driving video recording system 1000 based on whether the vehicle has been started, a measurement result of the vehicle battery voltage, whether a vehicle driving assistance function is required, an event detection result of the event detection sensor 120, etc.

[0047] Here, the recording modes of the driving video recording system 1000 can include a driving recording mode and a parking recording mode. Here, the driving recording mode can be a recording mode in a state where the engine of the vehicle is running, and the parking recording mode can be a recording mode in a state where the engine of the vehicle is stopped.

[0048] Additionally, the driving recording mode may include a continuous recording mode, an event recording mode, and a manual recording mode.

[0049] The continuous recording mode is executed when the vehicle engine is started and the vehicle starts to run, and the continuous recording mode can be maintained while the vehicle continues to run. In the continuous recording mode, the running video recording system 1000 can record at a predetermined time interval (for example, 1 to 5 minutes). In the present invention, the continuous recording mode and the constant mode can be used interchangeably.

[0050] The event recording mode may refer to a mode that is activated when an impact event is detected by the event detection sensor 120 while the vehicle is running, or an ADAS (Advanced Driving Assistance System) event is detected. In the event recording mode, the driving video recording system 1000 may record from a predetermined time before to a predetermined time after the event occurs (for example, recording from 10 seconds before to 10 seconds after the event occurs).

[0051] The manual recording mode may refer to a mode in which a user manually inputs and operates a recording while the vehicle is running. In the manual recording mode, the driving video recording system 1000 may record from a predetermined time before to a predetermined time after the user's manual recording request (for example, recording from 10 seconds before to 10 seconds after an event occurs).

[0052] The parking recording mode may refer to a mode in which the vehicle operates in a parked state with the engine of the vehicle stopped or the supply of power from the battery for driving the vehicle interrupted. In the parking recording mode, the driving video recording system 1000 may record when an event is detected by the event detection sensor 120 while the vehicle is parked. For example, the control unit 220 may control the camera 100 to record a predetermined section from a predetermined time before to a predetermined time after the occurrence of an impact event and / or an event of detecting an object approaching the vehicle (for example, recording from 10 seconds before to 10 seconds after the event occurrence).

[0053] Furthermore, the control unit 220 can control the power supply from the power supply unit 240 in accordance with the recording mode of the moving image recording system 1000 .

[0054] In particular, the control unit 220 may control the power supply of the power supply unit 240 in the parking recording mode to minimize the current consumption of the driving video recording system 1000. As an example, the control unit 220 may control the power supply unit 240 to turn off the power supply to the photographing unit 110 and turn on the power supply to the event detection sensor 120 in the parking recording mode.

[0055] The main body connector 230 can perform an interface function between the main body 200 and the camera 100, such as supplying power to the camera 100 and performing data communication.

[0056] The power supply unit 240 receives power from a battery of the vehicle in which the driving video recording system 1000 is installed, and can supply power to the driving video recording system 1000 for operation of the system 100 according to the control of the control unit 220.

[0057] Here, the battery supplying power to the power supply unit 240 may include at least one of a main battery for the vehicle in which the driving video recording system 1000 is installed and an auxiliary battery for the vehicle.

[0058] A vehicle main battery is a device that provides the power needed for all electronic devices and starting in a vehicle, and generally can start the vehicle's engine, maintain the electrical systems in the vehicle, and provide the power needed while driving.

[0059] The auxiliary vehicle battery can be a device that supplies power separately from the main vehicle battery so that the driving video recording system 1000 continues to operate when the vehicle engine is stopped.

[0060] Meanwhile, the camera connector 130 and the main body connector 230 may be connected to each other via a cable connecting them.

[0061] According to the present invention, the signal (power signal and data signal) lines of the photographing unit 110 that photographs videos and the signal (power signal and data signal) lines of the event detection sensor 120 that detects an event in the parking recording mode are configured separately from each other, and the control unit 220 controls each line separately, thereby minimizing the current consumption of the driving video recording system in the parking recording mode, and thus it is possible to expect the effect of increasing the recording time in the parking recording mode and extending the battery life.

[0062] Here, configuring the signal lines separately can include configuring each signal line physically separately from each other, but is not limited to this, and configuring the signal lines separately may be a concept including using the same physical configuration but configuring the signal lines separately by software signal transfer control.

[0063] Such a signal line according to the present invention will be described later with reference to FIG.

[0064] FIG. 2 is a block diagram specifically illustrating a driving video recording system according to another embodiment of the present invention. Referring to FIG. 2, a plurality of cameras 100-1, 100-2, ... 100-n may be connected to a main body 200. Here, each of the plurality of cameras 100-1, 100-2, ... 100-n may include all or some of a front camera, a rear camera for capturing the rear, a side camera for capturing the left and right sides, a camera for capturing the face of the vehicle driver, and a camera for capturing the interior of the vehicle. Videos captured by each of the capture units 110 may be transferred to the main body 200. Events detected by each of the event detection sensors 120 may be transferred to the main body 200. Here, the plurality of cameras 100-1, 100-2, ... 100-n and the main body 200 may communicate with each other in a serial transfer manner.

[0065] 3 is a block diagram specifically illustrating a driving video recording system according to an embodiment of the present invention. Referring to FIG. 3, the photographing unit 110 may include a lens unit 111, an image sensor 112, an image signal processor (ISP) 113, a serializer 114, and the like. The lens unit 111 may perform a function of collecting an optical signal, and the optical signal transmitted through the lens unit 111 reaches an imaging area of ​​the image sensor 112 to form an optical image. Here, the image sensor 112 may use a charge coupled device (CCD), a complementary metal oxide semiconductor image sensor (CIS), or a high-speed image sensor that converts an optical signal into an electrical signal.

[0066] The image sensor 112 may include an image signal processor (ISP) that processes raw data collected from the image sensor. The image signal processor may perform functions such as noise reduction, white balance adjustment, gamma correction, color filter correction, and tone mapping.

[0067] The serializer 114 converts a plurality of parallel data into one serial data, and transmits the converted data to a deserializer 211 of the image processor 210 of the main body 200 via a first camera connector 131 of the camera connector 130, a first main body connector 231 of the main body connector 230, and a cable connecting them.

[0068] Meanwhile, although not designated by a separate reference number, the photographing unit 110 may include a POC (Power Over Coax) filter, and when power and data signals are simultaneously transmitted through one coaxial cable, the photographing unit 110 can perform a function of separating the power supply and the data signal so that they are not mixed. That is, when power is supplied to the photographing unit 110 through a coaxial cable and a high-resolution video signal is transmitted, the power signal and the data signal may interfere with each other, but the POC filter can prevent this.

[0069] Furthermore, the image capture unit 110 may include a PMIC (Power Management IC), which may be a power management integrated circuit that efficiently supplies and manages power to the image capture unit 110.

[0070] The event detection sensor 120 may include all or some of an event sensing module 121 , an indicator 123 , and a DC-DC converter 122 .

[0071] The event sensing module 121 may include an impact event sensing module and a motion event sensing module. The impact event sensing module may be realized as a G-Sensor for sensing impact or acceleration, and the motion event sensing module may be realized as a radar sensor.

[0072] The DC-DC converter 122 is a device that converts a direct current (DC) voltage into another direct current (DC) voltage, and can convert the input DC voltage into a lower or higher DC voltage and supply the necessary power to the event sensing module 121.

[0073] The indicator 123 may be an LED indicator or a notification device that visually notifies a user of the status or operation of the driving video recording system 1000. For example, the indicator 123 may provide information such as whether the driving video recording system 1000 is operating normally, whether recording is being performed well, whether an error has occurred, etc., and may help a user easily grasp the status of the driving video recording system 1000. The indicator 123 may provide notification information to a user through various colors and blinking patterns.

[0074] The image processing unit 210 may include a deserializer 211 and an application processor 212 .

[0075] The deserializer 211 can perform the function of converting serialized data back to the original parallel data and restoring the data to its original form.

[0076] The application processor (AP) 212 is a processor that processes and analyzes images, and can further process basic video data processed by the image signal processor (ISP) 113 through more complex calculations. For example, the application processor 212 can perform AI-based image recognition, object tracking, etc.

[0077] For example, the application processor 212 can analyze the video captured by the image capture unit 110 and determine whether the above-mentioned driving assistance function (Advanced Driving Assistance System: ADAS) is necessary.

[0078] Meanwhile, according to the present invention, the signal (power signal and data signal) lines of the photographing unit 110 that photographs videos and the signal (power signal and data signal) lines of the event detection sensor 120 that detects an event in the parking recording mode are configured separately from each other, and the control unit 220 can control each line separately.

[0079] To this end, the power supply unit 240 includes a first power supply unit 241 and a second power supply unit 242, and the first power supply unit 241 and the second power supply unit 242 can be supplied with power from a battery of a vehicle in which the driving video recording system 1000 is installed.

[0080] The first power supply unit 241 may supply power for the operation of the photographing unit 110 and the image processing unit 210. The second power supply unit 242 may supply power for the operation of the event detection sensor 210.

[0081] The power supply of the first power supply unit 241 and the second power supply unit 242 can be controlled by the control unit 230.

[0082] Meanwhile, the camera connector 130 is formed on the camera 100 side and may include a first camera connector 131 that interfaces data communication between the photographing unit 110 and the image processing unit 210 and interfaces power supply between the photographing unit 110 and the first power supply unit 241.

[0083] In addition, the camera connector 130 may include a second camera connector 132 formed on the camera 100 side, which interfaces the power supply between the event detection sensor 120 and the second power supply unit 242 and interfaces data communication between the event detection sensor 120 and the control unit.

[0084] In addition, the body connector 230 may include a first body connector 231 formed on the body 200 side, which interfaces data communication between the photographing unit 110 and the image processing unit 210, and interfaces power supply between the photographing unit 110 and the first power supply unit 241.

[0085] In addition, the body connector 230 may include a second body connector 232 formed on the body 100 side, which interfaces the power supply between the event detection sensor 120 and the second power supply unit 242 and interfaces data communication between the event detection sensor 120 and the control unit.

[0086] For the "Conn." between the first camera connector 131 and the first main body connector 231, a 1-pin FAKRA connector can be used in the POC (Power Over Coax) system, and a 2-pin connector can be used in the PODL (Power Over Data Line) system. This allows data signals and power signals to be transmitted and received between the first camera connector 131 and the first main body connector 231.

[0087] In addition, the second camera connector 132 and the second main body connector 232 can use 2-pin connectors for "PWR1" and "SIG1". This allows data signals and power signals to be transmitted and received between the second camera connector 132 and the second main body connector 232.

[0088] Meanwhile, the camera connector 130 and the main body connector 230 may be connected to each other via a cable connecting them.

[0089] Meanwhile, the control unit 220 may control the overall operation of the driving video recording system 1000. Specifically, the control unit 220 may set a recording mode of the driving video recording system 1000 based on whether the vehicle has been started, a measurement result of the vehicle battery voltage, whether a vehicle driving assistance function is required, and a detection result of the event detection sensor 120. Here, the recording mode of the driving video recording system 1000 may include a driving recording mode and a parking recording mode.

[0090] Furthermore, the control unit 220 can control the power supply of the power supply unit 240 according to the recording mode of the driving video recording system 1000. Specifically, the control unit 220 can control the power supply of the power supply unit 240 so as to minimize the current consumption of the driving video recording system 1000 in the parking recording mode. That is, the control unit 220 can minimize the battery consumption of the vehicle by making the driving video recording system 1000 operate in a low power mode in the parking recording mode. The operation of the control unit 220 will be described later with reference to Figs. 6 to 7.

[0091] 4 and 5 are diagrams showing an embodiment of a driving video recording system according to an embodiment of the present invention. Referring to Fig. 4, the camera 100 and the main body 200 may be physically configured separately from each other. Also, the camera 100 and the main body 200 may be realized so as to be detachable from each other.

[0092] The main body 200 not only functions as a frame for installing the driving video recording system 1000 in a vehicle, but also can include an image processing unit 210, a control unit 220, a main body connector 230, and a power supply unit 240 in addition to the above.

[0093] In addition, the camera 100 can be removably installed in the main body 200, and the camera 100 can include an image capturing unit 110, an event detection sensor 120, and a camera connector .

[0094] 5, one region of the main body 200 may include a first input unit 301 that receives power from a main battery for a vehicle, and a second input unit 302 that supplies power from an auxiliary battery for a vehicle. The power inputted through the first input unit 301 and the second input unit 302 may be supplied to a power supply unit 240 inside the main body 200.

[0095] 6 to 7 are flowcharts showing a method of reducing current consumption under the control of the control unit 220 according to an embodiment of the present invention.

[0096] 6 is a flowchart showing a power supply control process in a driving recording mode and a parking recording mode according to an embodiment of the present invention. Referring to FIG. 6, the control unit 220 can set a recording mode of the driving video recording system 1000 (S11). As an example, the control unit 220 can set the driving recording mode when the vehicle engine is running, and set the parking recording mode when the vehicle engine is stopped.

[0097] When the driving recording mode is set (S12), the control unit 220 can control the power supply unit 240 to turn on the power supply by the first power supply unit 241 and turn off the power supply by the second power supply unit 242 (S13).

[0098] In this case, the photographing unit 110 and the image processing unit 210 can be supplied with power from the first power supply unit 241 through the first camera connector 131 and the first main body connector 231, and the photographing unit 110 and the image processing unit 210 can operate (S14). A moving image photographed by the photographing unit 110 according to the operation of the photographing unit 110 and the image processing unit 210 is transferred to the image processing unit 210, and the image processing unit 210 can process the moving image. However, since the power supply from the second power supply unit 242 to the event detection sensor 120 is cut off through the second camera connector 132 and the second main body connector 232, the event detection sensor 120 cannot operate (S15).

[0099] On the other hand, when the parking recording mode is set (S16), the control unit 220 can control the power supply unit 240 to turn off the power supply by the first power supply unit 241 and turn on the power supply by the second power supply unit 242 (S17).

[0100] In this case, the power supply from the first power supply unit 241 to the photographing unit 110 and the image processing unit 210 is cut off by the first camera connector 131 and the first main body connector 231, so that the photographing unit 110 and the image processing unit 210 do not operate any further (enter a shutdown state) (S18), and the photographing unit 110 and the image processing unit 210 no longer consume current.

[0101] Conversely, the event detection sensor 120 can operate since the supply of power from the second power supply unit 242 has started through the second camera connector 132 and the second main body connector 232 (S19).

[0102] Meanwhile, in step S19, a method of reducing current consumption of the driving video recording system 1000 when an impact or motion is detected outside the vehicle while the event detection sensor 120 is operating will be described with reference to FIG.

[0103] 7 is a flowchart illustrating a method for reducing current consumption of the driving video recording system 1000 when an event occurs outside the vehicle according to an embodiment of the present invention. Referring to FIG 7, during the parking recording mode, the event detection sensor 120 operates to detect an event in real time (S21).

[0104] For example, when at least one of an impact event and / or a motion event is detected (S21: Y), the event detection sensor 120 may generate an interrupt and transmit it to the control unit 220 (S22). Such an interrupt signal may be transmitted to the control unit 220 via the second camera connector 132 and the second body connector 232.

[0105] The control unit 220 that has received the interrupt can control the power supply unit 240 to turn on the power supply by the first power supply unit 241 (S24). In this case, the photographing unit 110 and the image processing unit 210 can be supplied with power from the first power supply unit 241 by the first camera connector 131 and the first main body connector 231, and the photographing unit 110 and the image processing unit 210 can wake up and operate (S25). Depending on the operation of the photographing unit 110 and the image processing unit 210, the moving image captured by the photographing unit 110 is transferred to the image processing unit 210, and the image processing unit 210 can process the moving image.

[0106] Meanwhile, when the work of the photographing unit 110 and the image processing unit 210 is completed (S26: Y), the control unit 220 may control the power supply unit 240 to turn off the power supply from the first power supply unit 241 (S27). Here, the completion of the work may include, for example, a state in which the event detection sensor 120 has finished detecting the event.

[0107] In this case, the power supply to all components other than the event detection sensor 120 and the control unit 220 is shut down, and current consumption can be minimized.

[0108] According to the present invention, the signal lines (power supply signal and data signal) of the photographing unit that photographs videos and the signal lines (power supply signal and data signal) of the event detection sensor that detects an event in parking recording mode are configured separately, and the control unit controls each line separately, thereby minimizing the current consumption of the driving video recording system in parking recording mode, and thus it is possible to expect the effects of increasing the recording time in parking recording mode and extending the battery life.

[0109] An autonomous driving system, an autonomous driving vehicle, and a user device using various information, data, videos, etc. collected by the driving video recording system 1000 according to the present invention will be described in more detail below with reference to Figs. 8 to 11.

[0122] According to an embodiment, the autonomous driving system 800 illustrated in Fig. 8 may be configured in an electronic device of a vehicle. According to an embodiment, when an autonomous driving cancellation event occurs from a user during autonomous driving of the vehicle, the AI ​​processor 809 of the autonomous driving system 800 may control the autonomous driving software of the vehicle to learn by controlling the input of information related to the autonomous driving cancellation event as training set data of the deep learning network.

[0123] 8 and 10 are diagrams illustrating an example of a block diagram showing an autonomous vehicle according to an embodiment. Referring to FIG. 9, an autonomous vehicle 900 according to the present embodiment may include a control device 1000, sensing modules 904a, 904b, 904c, and 904d, an engine 906, and a user interface 908.

[0124] The autonomous vehicle 900 may have an autonomous driving mode or a manual mode. For example, the autonomous vehicle 900 may be switched from the manual mode to the autonomous driving mode or from the autonomous driving mode to the manual mode in response to a user input received via the user interface 908.

[0125] When the vehicle 900 is operated in an autonomous driving mode, the autonomous driving vehicle 900 can operate under the control of the control device 1000.

[0126] In this embodiment, the control device 1000 may include a controller 1020 including a memory 1022 and a processor 1024 , a sensor 1010 , a communication device 1030 , and an object detection device 1040 .

[0127] Here, the object detection device 1040 can perform all or part of the functions of a distance measurement device (eg, the electronic device 101).

[0128] That is, in this embodiment, the object detection device 1040 is a device for detecting objects located outside the moving body 900, and the object detection device 1040 can detect objects located outside the moving body 900 and generate object information based on the detection results.

[0129] The object information can include information regarding the presence or absence of an object, position information of the object, distance information between the moving body and the object, and relative speed information between the moving body and the object.

[0130] The object may include various objects located outside the moving body 900, such as a lane, another vehicle, a pedestrian, a traffic signal, a light, a road, a structure, a speed limiter, a topographical object, an animal, etc. Here, the traffic signal may be a concept including a traffic light, a traffic sign, and a pattern or text drawn on the road surface. Also, the light may be light generated from a lamp provided on another vehicle, light generated from a street lamp, or sunlight.

[0131] The structures may be objects that are fixed to the ground and are located around the road. For example, the structures may include street lights, roadside trees, buildings, utility poles, traffic lights, bridges, etc. The terrain objects may include mountains, hills, etc.

[0132] The object detection device 1040 may include a camera module. The controller 1020 may extract object information from an external image captured by the camera module and process the information.

[0133] The object detection device 1040 may further include an imaging device for recognizing the external environment. In addition to LIDAR, RADAR, GPS devices, odometry and other computer vision devices, ultrasonic sensors, and infrared sensors may be used, which may be selectively or simultaneously operated as needed to enable more precise sensing.

[0134] Meanwhile, a distance measuring device according to one embodiment of the present invention can calculate the distance between an autonomous vehicle 900 and an object, and control the operation of the vehicle based on the calculated distance in cooperation with a control device 1000 of the autonomous vehicle 900.

[0135] As an example, if there is a possibility of a collision depending on the distance between the autonomous traveling vehicle 900 and the object, the autonomous traveling vehicle 900 can control the brakes to reduce speed or stop. As another example, if the object is a moving object, the autonomous traveling vehicle 900 can control the traveling speed of the autonomous traveling vehicle 900 to maintain a predetermined distance or more from the object.

[0136] Such a distance measurement device according to an embodiment of the present invention can be configured as one module in the control device 1000 of the autonomous vehicle 900. That is, the memory 1022 and the processor 1024 of the control device 1000 can realize the collision prevention method according to the present invention in software form.

[0137] Also, the sensor 1010 can acquire various sensing information by connecting the internal / external environment of the moving object to the sensing modules 904a, 904b, 904c, and 904d. Here, the sensor 1010 can include an attitude sensor (e.g., a yaw sensor, a roll sensor, a pitch sensor, a collision sensor, a wheel sensor, a speed sensor, an inclination sensor, a weight detection sensor, a heading sensor, a gyro sensor, a position module, a moving object forward / backward sensor, a battery sensor, a fuel sensor, a tire sensor, a steering sensor based on the rotation of a steering wheel, a moving object internal temperature sensor, a moving object internal humidity sensor, an ultrasonic sensor, an illuminance sensor, an accelerator pedal position sensor, a brake pedal position sensor, etc.

[0138] This enables the sensor 1010 to acquire sensing signals relating to posture information of the moving body, collision information of the moving body, directional information of the moving body, position information (GPS information) of the moving body, angle information of the moving body, speed information of the moving body, acceleration information of the moving body, gradient information of the moving body, forward / reverse information of the moving body, battery information, fuel information, tire information, lamp information of the moving body, internal temperature information of the moving body, internal humidity information of the moving body, rotation angle of the steering wheel, external illuminance of the moving body, pressure applied to the accelerator pedal, pressure applied to the brake pedal, etc.

[0139] In addition, the sensor 1010 may further include an accelerator pedal sensor, a pressure sensor, an engine speed sensor, an air flow sensor (AFS), an intake temperature sensor (ATS), a water temperature sensor (WTS), a throttle position sensor (TPS), a TDC sensor, a crank angle sensor (CAS), and the like.

[0140] In this manner, the sensor 1010 can generate status information of the moving object based on the sensing data.

[0141] The wireless communication device 1030 is configured to realize wireless communication between the autonomous mobile bodies 900. For example, the autonomous mobile body 900 can communicate with a user's mobile phone, another wireless communication device 1030, another mobile body, a central device (traffic control device), a server, etc. The wireless communication device 1030 can transmit and receive wireless signals by an access wireless protocol. The wireless communication protocol can be Wi-Fi, Bluetooth, Long-Term Evolution (LTE), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Global Systems for Mobile Communications (GSM), and the communication protocol is not limited thereto.

[0142] In addition, in this embodiment, the autonomous traveling moving body 900 can also realize communication between moving bodies by the wireless communication device 1030. That is, the wireless communication device 1030 can communicate with other moving bodies on the road and other moving bodies by vehicle-to-vehicle (V2V) communication. The autonomous traveling moving body 900 can transmit and receive information such as driving warnings and traffic information by vehicle-to-vehicle communication, and can also request information from other moving bodies or receive requests. For example, the wireless communication device 1030 can perform V2V communication by a dedicated short-range communication (DSRC) device or a Cellular-V2V (C-V2V) device. In addition to communication between vehicles, communication between vehicles and other things (e.g., electronic devices carried by pedestrians, etc.) (V2X, Vehicle to Everything communication) can also be realized by the wireless communication device 1030.

[0143] In this embodiment, the controller 1020 is a unit that controls the overall operation of each unit in the moving body 900, and may be configured by the manufacturer of the moving body at the time of manufacture or may be additionally configured after manufacture to perform the function of autonomous driving. Alternatively, the controller 1020 configured at the time of manufacture may be upgraded to include a configuration for continuously performing additional functions. Such a controller 1020 may also be referred to as an ECU (Electronic Control Unit).

[0144] The controller 1020 can collect various data from the connected sensor 1010, the object detection device 1040, the communication device 1030, etc., and transmit control signals based on the collected data to the sensor 1010, the engine 906, the user interface 908, the communication device 1030, and the object detection device 1040 included as other components in the vehicle. In addition, although not shown, the controller 1020 can also transmit control signals to an acceleration device, a braking system, a steering device, or a navigation device related to the running of the vehicle.

[0145] In this embodiment, the controller 1020 can control the engine 906, for example, by detecting the speed limit of the road on which the autonomous vehicle 900 is traveling and controlling the engine 906 so that the traveling speed does not exceed the speed limit, or by controlling the engine 906 to accelerate the traveling speed of the autonomous vehicle 900 within a range that does not exceed the speed limit.

[0146] In addition, when the autonomous traveling mobile body 900 approaches a lane or departs from a lane during the traveling of the autonomous traveling mobile body 900, the controller 1020 can control the engine 906 to determine whether such approach and departure from the lane are due to a normal traveling situation or due to other traveling situations, and control the traveling of the mobile body according to the determination result. Specifically, the autonomous traveling mobile body 900 can detect lanes formed on both sides of the road on which the mobile body is traveling. In this case, the controller 1020 can determine whether the autonomous traveling mobile body 900 approaches a lane or departs from the lane, and, for example, when it is determined that the autonomous traveling mobile body 900 approaches a lane or departs from the lane, it can determine whether such traveling is due to a correct traveling situation or due to other traveling situations. Here, an example of a normal traveling situation can be a situation in which a lane change of the mobile body is required. In addition, an example of a traveling situation in which a lane change of the mobile body is not required can be. For example, when the controller 1020 determines that the autonomously driving vehicle 900 is approaching a lane or leaving a lane in a situation where the vehicle does not need to change lanes, the controller 1020 can control the driving of the autonomously driving vehicle 900 so that the autonomously driving vehicle 900 does not leave the lane and drives normally.

[0147] If there is another moving object or an obstacle ahead of the moving object, the engine 906 or the braking system can be controlled to decelerate the moving object, and the trajectory, driving route, steering angle, and other information other than the speed can be controlled. Alternatively, the controller 1020 can generate necessary control signals according to other external environment recognition information such as the lane the moving object is traveling in, driving signals, and the like, to control the traveling of the moving object.

[0148] In addition to generating its own control signals, the controller 1020 can also control the movement of the mobile object by communicating with surrounding mobile objects or a central server and transferring commands to control peripheral devices based on the information received.

[0149] In addition, when the position or angle of view of the camera module 1050 is changed, accurate recognition of the moving body or lane according to the present embodiment may be difficult. To prevent this, the controller 1020 may generate a control signal to control the camera module 1050 to perform calibration. Therefore, in the present embodiment, the controller 1020 generates a calibration control signal to the camera module 1050, so that the normal mounting position, direction, angle of view, etc. of the camera module 1050 can be continuously maintained even if the mounting position of the camera module 1050 is changed due to vibration or impact generated according to the movement of the autonomous traveling moving body 900. The controller 1020 may generate a control signal to perform calibration of the camera module 1050 when the initial mounting position, direction, angle of view information of the camera module 1050 stored in advance and the initial mounting position, direction, angle of view information of the camera module 1050 measured during the traveling of the autonomous traveling moving body 900 change by more than a critical value.

[0150] In this embodiment, the controller 1020 may include a memory 1022 and a processor 1024. The processor 1024 may execute software stored in the memory 1022 in response to control signals from the controller 1020. In particular, the controller 1020 may store data and instructions for performing a lane detection method in accordance with the present invention in the memory 1022, and the instructions may be executed by the processor 1024 to implement one or more of the methods disclosed herein.

[0151] Here, the memory 1022 may be stored in a non-volatile recording medium executable by the processor 1024. The memory 1022 may store software and data in an appropriate internal or external device. The memory 1022 may be configured as a random access memory (RAM), a read only memory (ROM), a hard disk, or a memory 1022 device connected to a dongle.

[0152] The memory 1022 may store at least an operating system (OS), user applications, and executable instructions. The memory 1022 may also store application data and array data structures.

[0153] The processor 1024 is a microprocessor or any suitable electronic processor, and can be a controller, microcontroller, or a state machine.

[0154] The processor 1024 may be implemented by a combination of computing devices, which may be digital signal processors, microprocessors, or any suitable combination thereof.

[0155] Meanwhile, the autonomous vehicle 900 may further include a user interface 908 for user input to the control device 1000 described above. The user interface 908 may allow the user to input information through appropriate interaction. For example, the user interface 908 may be realized by a touch screen, a keypad, an operation button, or the like. The user interface 908 may transfer the input or command to the controller 1020, and the controller 1020 may perform a control operation of the vehicle in response to the input or command.

[0156] The user interface 908 is a device external to the autonomous vehicle 900 and can communicate with the autonomous vehicle 900 via the wireless communication device 1030. For example, the user interface 908 can be linked to a mobile phone, a tablet, or other computer device.

[0157] Furthermore, in this embodiment, the autonomous vehicle 900 is described as including the engine 906, but may include other types of propulsion systems. For example, the vehicle may be powered by electric energy, hydrogen energy, or a hybrid system that combines these. Thus, the controller 1020 may include the propulsion mechanisms of the propulsion system of the autonomous vehicle 900 and provide control signals to the configuration of each propulsion mechanism.

[0158] Hereinafter, the detailed configuration of the control device 1000 according to the present embodiment will be described in more detail with reference to FIG.

[0159] The controller 1000 includes a processor 1024. The processor 1024 may be a general purpose single or multi-chip microprocessor, a special purpose microprocessor, a microcontroller, a programmable gate array, etc. The processor may also be referred to as a central processing unit (CPU).

[0161] Data and instructions 1022a for performing the distance measuring method of the distance measuring device according to the present invention may be stored in memory 1022. When processor 1024 executes instructions 1022a, all or a part of instructions 1022a and data 1022b required to execute the instructions may be loaded onto processor 1024 as instructions 1024a and data 1024b.

The communication interface 1080 may allow a user and the control device 1000 to interact.

[0165] The various components of the controller 1000 may be coupled together by one or more buses 1090, which may include a power bus, a control signal bus, a status signal bus, a data bus, etc. Under the control of the processor 1024, the components may communicate information to each other via the bus 1090 to perform their intended functions.

[0166] Meanwhile, in various embodiments, the control device 1000 may be associated with a gateway for communication with the security cloud. For example, referring to FIG. 20, the control device 1000 may be associated with a gateway 1105 for providing information acquired from at least one of the components 1101 to 1104 of the vehicle 1100 to the security cloud 1106. For example, the gateway 1105 may be included in the control device 1000. As another example, the gateway 1105 may be configured as a separate device in the vehicle 1100 distinct from the control device 1000. The gateway 1105 communicatively connects the software management cloud 1109, the security cloud 1106, and the network in the vehicle 1100 secured by the in-vehicle security software 1110, which have different networks from each other.

[0167] For example, the component 1101 may be a sensor. For example, the sensor may be used to obtain information about at least one of a state of the vehicle 1100 or a state around the vehicle 1100. For example, the component 1101 may include a sensor 1410.

[0168] For example, the component 1102 may be an electronic control unit (ECU), which may be used, for example, to control an engine, a transmission, an airbag, or to manage tire pressure.

[0169] For example, the component 1103 may be an instrument cluster. For example, the instrument cluster may refer to a panel located in front of the driver's seat in a dashboard. For example, the instrument cluster may be configured to show information required for driving to a driver (or passenger). For example, the instrument cluster may be used to display at least one of a visual element for indicating the revolutions per minute (RPM, revolutions per minute or rotate per minute) of an engine, a visual element for indicating the speed of the vehicle 1100, a visual element for indicating the amount of remaining fuel, a visual element for indicating the state of the gear, or a visual element for indicating information obtained by the component 1101.

[0170] For example, the component 1104 may be a telematics device. For example, the telematics device may refer to a device that combines wireless communication technology and Global Positioning System (GPS) technology to provide various mobile communication services such as location information, safe driving, etc. in the vehicle 1100. For example, the telematics device may be used to connect the vehicle 1100 with a driver, a cloud (e.g., security cloud 1106), and / or the surrounding environment. For example, the telematics device may be configured to support high bandwidth and low latency for 5G NR standard technology (e.g., 5G NR V2X technology). For example, the telematics device may be configured to support autonomous driving of the vehicle 1100.

[0171] For example, the gateway 1105 may be used to connect a network in the vehicle 1100 with a software management cloud 1109 and a security cloud 1106, which are networks outside the vehicle. For example, the software management cloud 1109 may be used to update or manage at least one software required for running and managing the vehicle 1100. For example, the software management cloud 1109 may work with in-car security software 1110 installed in the vehicle. For example, the in-car security software 1110 may be used to provide a security function in the vehicle 1100. For example, the in-car security software 1110 may encrypt data transmitted and received via the in-vehicle network using an encryption key obtained from an external authorized server for encryption of the network in the vehicle. In various embodiments, the encryption key used by the in-vehicle security software 1110 may be generated in response to vehicle identification information (vehicle license plate, vehicle identification number (VIN)) or information uniquely assigned to each user (e.g., user identification information).

[0172] In various embodiments, the gateway 1105 can transmit data encrypted by the in-vehicle security software 1110 based on the encryption key to the software management cloud 1109 and / or the security cloud 1106. The software management cloud 1109 and / or the security cloud 1106 can identify which vehicle or which user the data is received from by decrypting the data using a decryption key that can decrypt the data encrypted by the encryption key of the in-vehicle security software 1110. For example, since the decryption key is a unique key corresponding to the encryption key, the software management cloud 1109 and / or the security cloud 1106 can identify the sender of the data (e.g., the vehicle or the user) based on the data decrypted by the decryption key.

[0173] For example, the gateway 1105 may be configured to support the in-vehicle security software 1110 and may be associated with the control device 1000. For example, the gateway 1105 may be associated with the control device 1000 to support the connection between the control device 1000 and a client device 1107 connected to the security cloud 1106. As another example, the gateway 1105 may be associated with the control device 1000 to support the connection between the control device 1000 and a third party cloud 1108 connected to the security cloud 1106. However, the present invention is not limited thereto.

[0174] In various embodiments, the gateway 1105 can be used to connect the vehicle 1100 to a software management cloud 1109 for managing the operating software of the vehicle 1100. For example, the software management cloud 1109 can monitor whether an update to the operating software of the vehicle 1100 is required, and provide data for updating the operating software of the vehicle 1100 via the gateway 1105 based on monitoring that an update to the operating software of the vehicle 1100 is required. As another example, the software management cloud 1109 can receive a user request for updating the operating software of the vehicle 1100 from the vehicle 1100 via the gateway 1105, and provide data for updating the operating software of the vehicle 1100 based on the reception. However, this is not limiting.
