Description

Technical Field

[0001] The present invention relates to a technology for reducing the current consumption in the parking recording mode by using a motion sensing function.

Background Art

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

[0003] The driving video recording system can be installed in various vehicles such as taxis, buses, and patrol cars. Generally, it can be composed of a camera that shoots the inside and outside of the vehicle, a memory that stores the shot videos, a GPS module that records and tracks the position of the vehicle, and a display that can view the videos in real time.

[0004] Such a driving video recording system includes a driving recording mode that is activated in the driving situation of the vehicle and records the situations occurring during the driving of the vehicle, and a parking recording mode that is activated in the parking situation of the vehicle and records the situations occurring during the parking of the vehicle.

[0005] Even when the driving video recording system enters the parking recording mode, it consumes a current of several tens of mA to several hundreds of mA for continuous video recording. Due to this current, problems such as a reduction in the battery life or discharge may occur.

[0006] To improve this, the driving video recording system suspends all functions in the parking recording mode, waits while performing only some necessary operations, and when an interrupt occurs due to sensing by the event sensing sensor, a technology is added to wake up all functions and record and store videos. Here, as the event sensing sensor, a G-Sensor for sensing external impacts, a radar sensor for sensing external objects, etc. are used, and the event sensing sensor is incorporated into the main body and can be easily controlled.

[0007] Since the event sensing sensor is incorporated into the main body or connected via an FPCB (Flexible Printed Circuit Board) or a board-to-board connector, a signal line that directly receives power supply, senses events, and transfers interrupts is assigned, and it can be easily controlled.

[0008] On the other hand, among the main body and the camera that are physically configured separately from each other, when an event sensing sensor is incorporated into the camera, the camera receives power supply from the main body in a POC (Power Over Coax) method or a PODL (Power Over Data Line) method that applies power to the video signal line, and this power becomes the main power supply for the shooting unit of the camera and the event sensing sensor. Here, through the combination of the serializer of the camera and the deserializer of the main body (hereinafter generally referred to as SERDES), the camera transfers videos and data to the main body, and for this purpose, power must always be applied to the camera.

[0009] Also, the event sensing sensor incorporated into the camera also transfers the object sensing signal to the main body via the SERDES. However, when the event sensing sensor senses an object and tries to transfer an interrupt to the main body in the parking recording mode, the SERDES must be operating, and for this reason, there is a problem of consuming a large amount of current. Summary of the Invention

Problems to be Solved by the Invention

[0010] The present invention has been derived from the above-mentioned necessity, and an object of the present invention is to provide a method for minimizing power consumption in a traveling video recording system including a main body physically separately configured from each other and a camera incorporating a motion sensor.

Means for Solving the Problems

[0011] A traveling video recording system according to an exemplary embodiment of the present invention includes a camera including a photographing unit that photographs a video, an event sensing unit that senses an event, and a camera connector for an interface with the main body, an image processing unit that receives and processes the video photographed by the photographing unit, a power supply unit that supplies power for the operation of the traveling video recording system, a control unit that controls the operation of the power supply unit, and a main body including a main body connector for an interface with the camera. In the parking recording mode, the control unit controls to turn off the power supply to the photographing unit and turn on the power supply to the event sensing unit among the configurations of the camera, and turn off the power supply to the image processing unit and turn on the power supply to the power supply unit among the configurations of the main body.

[0012] The event sensing unit may include at least one of a shock event sensing sensor and a motion event sensing sensor.

[0013] The event sensing unit may further include a voltage control unit for converting a voltage transmitted to the main body based on an interrupt signal generated from at least one of the shock event sensing sensor and the motion event sensing sensor, and the voltage control unit may operate to increase or decrease the voltage when the occurrence of shock or motion is sensed by at least one of the shock event sensing sensor and the motion event sensing sensor.

[0014] The main body may further include a voltage sensing unit that senses a voltage change of the camera. When the control unit senses a voltage change by the voltage sensing unit, the control unit can control the imaging unit and the image processing unit to turn on the power supply respectively.

[0015] The voltage control unit may be composed of transistors. If the control unit does not sense the occurrence of the impact or motion, the control unit turns on the power supply of the transistors by the power supply unit. When the occurrence of the impact or motion is sensed, the control unit turns off the power supply of the transistors by the power supply unit and can control to reduce the normal voltage in the parking recording mode.

[0016] The voltage control unit may be composed of a DC / DC converter. When the control unit senses the occurrence of the impact or motion, the control unit can control the DC / DC converter to increase the normal voltage in the parking recording mode.

[0017] The event sensing unit may further include a current control unit for converting a current transmitted to the main body based on an interrupt signal generated from at least one of the impact event sensing sensor and the motion event sensing sensor. When the occurrence of an impact or motion is sensed by at least one of the impact event sensing sensor and the motion event sensing sensor, the current control unit can operate to increase or decrease the current.

[0018] The main body may further include a current sensing unit that senses a current change of the camera. When the control unit senses a current change by the current sensing unit, the control unit can control the imaging unit and the image processing unit to turn on the power supply respectively.

[0019] The current control unit can be composed of a FET (Field-Effect Transistor). If no impact or motion is detected, the control unit turns on the power supply to the FET by the power supply unit. When an impact or motion is detected, the control unit turns off the power supply to the FET by the power supply unit, and can control to reduce the normal current in the parking recording mode.

[0020] The current control unit can be composed of a load circuit. When an impact or motion is detected, the control unit can control to increase the normal current in the parking recording mode by activating the load circuit.

[0021] The current control unit can be composed of a transmission power supply unit for outputting transmission power to the main body connector according to a preset value in the parking recording mode, and a transmission power conversion unit for changing the period or amplitude of the transmission power. When an impact or motion is detected, the control unit can control to generate a peak current in the parking recording mode by increasing or decreasing the period or amplitude of the transmission power by the transmission power conversion unit.

[0022] The main body can further include a current sensing unit for sensing a current change of the camera. When the generation of the peak current is sensed by the current sensing unit, the control unit can control to turn on the power supply to the imaging unit and the image processing unit, respectively.

[0023] The event sensing unit may further include a voltage / current control unit for converting at least one of the normal voltage and the normal current in the parking recording mode based on an interrupt signal generated from at least one of the impact event sensing sensor and the motion event sensing sensor. When the generation of an impact or motion is sensed by at least one of the impact event sensing sensor and the motion event sensing sensor, the voltage / current control unit can be operated to increase or decrease at least one of the normal voltage and the normal current.

[0024] The main body may further include a status pin whose voltage changes in response to a change in the state of the power line supplied by the power supply unit, and a status pin voltage confirmation unit for sensing the voltage of the status pin. When it is sensed that at least one of the voltage and the current received from the camera is smaller or larger than a preset value, the status pin can be operated to increase or decrease its voltage.

[0025] When the control unit senses a voltage change of the status pin by the status pin voltage confirmation unit, it can control the imaging unit and the image processing unit to turn on the power supply, respectively.

[0026] In a method for reducing the power consumption of a driving video recording system according to an exemplary embodiment of the present invention, the driving video recording system may include a photographing unit that photographs a driving video, an event sensing unit that senses an event during parking and generates an interrupt signal when the event is sensed, a camera including a camera connector for connection to a main body, an image processing unit that receives and processes the video photographed by the photographing unit, a power supply unit that supplies power for the operation of the driving video recording system, a control unit that controls the operation of the power supply unit, and a main body including a main body connector for an interface with the camera. The method for reducing the power consumption may include controlling the power supply unit to turn off the power supply to the photographing unit and turn on the power supply to the event sensing sensor in a parking recording mode; controlling the control unit to change the state of a power line when the interrupt signal is sensed from the event sensing unit; and controlling the control unit to turn on the power supply to the photographing unit and the image processing unit, respectively, when the change in the state of the power line is sensed.

[0027] The change in the state of the power line can be performed by increasing or decreasing at least one of a normal voltage and a normal current in the parking recording mode.

[0028] The change in the state of the power line can be performed by changing a period or an amplitude of transmission power transmitted from the camera to the main body according to a preset value in the parking recording mode.

[0029] On the other hand, a computer-readable recording medium according to an embodiment of the present invention for achieving the above object may record a program for executing the method for reducing the power consumption of the driving video recording system described above.

[0030] Also, a computer program according to an embodiment of the present invention for achieving the above object may include program code for executing a method for reducing the power consumption of a driving video recording system.

Advantages of the Invention

[0031] According to the present invention, in a driving video recording system including a camera in which a main body physically separately configured from each other and a motion sensing sensor are incorporated, the power consumption can be minimized.

[0032] In addition, the camera in the present invention can be controlled to change the voltage, current, transmission power (TX Power), etc. transmitted to the main body based on an interrupt signal generated from an event sensing sensor for realizing a motion sensing function. The main body can be controlled so that power is supplied to the imaging unit only when an event occurs by sensing the changed voltage, current, transmission power, etc. Thereby, in the parking recording mode, the power consumption of the driving video recording system can be minimized, and thereby, the effects of increasing the recording time and battery life in the parking recording mode can be maximized.

However, this is merely an example and the present invention is not limited thereto.

These terms are for distinguishing the components from other components, and the essence, procedure, order, etc. of the components are not limited by these terms.

[0037] Hereinafter, various embodiments of the present invention will be described in detail with reference to the drawings.

[0038] FIG. 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 provided in a vehicle, captures video in situations such as the vehicle's driving, stopping, and parking, and stores the captured video, and can include a camera 100 and a main body 200.

[0039] Here, the camera 100 and the main body 200 can be physically separated from each other and configured individually.

[0040] In the present invention, the 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 according to the present invention can include various movable objects such as a vehicle, a person, a bicycle, a ship, a train, and the like. Hereinafter, for convenience of explanation, the case where the moving body is a vehicle will be described as an example.

[0041] Also, in this specification, an act of triggering 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, and the like. Here, the driving video recording system 1000 can include all or part of a front shooting device that shoots the front of the vehicle, a rear shooting device that shoots the rear, a side shooting device that shoots the left and right sides, a shooting device that shoots the face of the vehicle driver, and an in-vehicle shooting device that shoots the interior of the vehicle.

[0042] An in-vehicle infrared camera, an in-vehicle black box, a car dash cam, or a car video recorder are other expressions of the driving video recording system 1000, and all can mean the same thing.

[0043] Referring to FIG. 1, the camera 100 includes a shooting unit 110, an event sensing unit 120, and a camera connector 130.

[0044] The imaging unit 110 can capture the surrounding video of the moving body. Here, the video is a video captured in at least one situation during the parking, stopping, and driving of the vehicle, and can include at least one of the videos of the front, rear, side, and inside of the vehicle. Here, the imaging unit 110 may include an infrared camera capable of monitoring the face or pupils of the driver, and the control unit 220 can determine the state of the driver, including whether the driver is dozing off, by monitoring the face or pupils of the driver through the infrared camera.

[0045] Such an imaging unit 110 can include a lens unit, an image sensor, an image signal processor (ISP), a serializer, and the like.

[0046] The event sensing unit 120 is a sensor for sensing events, and can include a shock event sensing sensor for sensing the shock applied to the vehicle and / or a motion event sensing sensor for sensing objects such as people, vehicles, and animals approaching the vehicle. However, it is not limited to this, and the event sensing unit 120 can be a concept including sensors for sensing various events that trigger the operation of the driving video recording system 1000. In one embodiment, the event sensing unit 120 can include at least one of a shock event sensing sensor and a motion event sensing sensor.

[0047] The camera connector 130 can perform the interface function between the camera 100 and the main body 200, such as receiving the power supply of the main body 200 and performing data communication.

[0048] On the other hand, the main body 200 includes an image processing unit 210, a control unit 220, a main body connector 230, and a power supply unit 240.

[0049] The image processing unit 210 can receive, process, and store in a memory (not shown) the video captured by the imaging unit 110. As an example, the image processing unit 210 can analyze the video received from the camera 100 and perform an analysis to determine whether an advanced driving assistance system (ADAS) is required for the driver of the vehicle. Here, the driving assistance function can include sensing the start of a vehicle located in front of the vehicle and guiding the driver on whether a forward vehicle start alarm (FVSA) is required, sensing the presence or absence of a signal change and guiding the driver on whether a traffic light change alarm (TLCA) is required, sensing the presence or absence of the vehicle leaving the lane and guiding the driver on whether a lane departure warning system (LDWS) is required, sensing the risk of collision with a vehicle in front of the vehicle and guiding the driver on whether a forward collision warning system (FCWS) is required, and so on.

[0050] The control unit 220 can control the overall operation of the driving video recording system 1000. Specifically, the control unit 220 can set the recording mode of the driving video recording system 1000 based on, for example, the presence or absence of vehicle startup, the measurement result of the vehicle battery voltage, the necessity of the vehicle driving assistance function, the event sensing result of the event sensing unit 120, and so on.

[0051] Here, the recording mode 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 when the vehicle engine is running, and the parking recording mode can be a recording mode when the vehicle engine is stopped.

[0052] Also, the driving recording mode can include a continuous recording mode, an event recording mode, and a manual recording mode.

[0053] The continuous recording mode is a mode that is executed when the vehicle engine is started and driving begins, and can be maintained while the vehicle is in motion. In the continuous recording mode, the driving video recording system 1000 can record in a predetermined time unit (for example, 1 to 5 minutes). In the present invention, the continuous recording mode and the continuous mode can be used interchangeably.

[0054] The event recording mode may mean a mode that is activated when an impact event is detected by the event detection unit 120 or an ADAS (Advanced Driving Assistance System) event is detected during vehicle driving. In the event recording mode, the driving video recording system 1000 can record for a period of time from a predetermined time before the event occurs to a predetermined time after the event occurs (for example, recording from 10 seconds before the event occurs to 10 seconds after the event occurs).

[0055] The manual recording mode may mean a mode that is activated when the user manually inputs a recording during vehicle driving. In the manual recording mode, the driving video recording system 1000 can record for a period of time from a predetermined time before the user's manual recording request occurs to a predetermined time after the request occurs (for example, recording from 10 seconds before the event occurs to 10 seconds after the event occurs).

[0056] The parking recording mode may mean a mode that operates in a parked state when the vehicle engine stops or the battery supply for vehicle driving is interrupted. In the parking recording mode, the driving video recording system 1000 can record when an event is detected by the event detection unit 120 during parking. As an example, the control unit 220 can control the camera 100 to record a predetermined section from a predetermined time before the impact event occurs and / or the thing approaching event occurs to a predetermined time after the event occurs (for example, recording from 10 seconds before the event occurs to 10 seconds after the event occurs).

[0057] In addition, the control unit 220 can control the power supply of the power supply unit 240 according to the recording mode of the video recording system 1000.

[0058] In particular, the control unit 220 can control the power supply of the power supply unit 240 so that the current consumption of the driving video recording system 1000 is minimized in the parking recording mode. As an example, the control unit 220 can control the power supply unit 240 so as to turn off the power supply to the imaging unit 110 and turn on the power supply to the event detection unit 120 in the parking recording mode.

[0059] 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.

[0060] The power supply unit 240 receives power supply from the battery of the vehicle in which the driving video recording system 1000 is installed, and can supply power for the operation of the system 100 to the driving video recording system 1000 according to the control of the control unit 220.

[0061] Here, the battery that supplies power to the power supply unit 240 can include at least one of the main battery for the vehicle and the auxiliary battery for the vehicle in which the driving video recording system 1000 is installed.

[0062] The main battery for the vehicle is a device that supplies power necessary for starting all the electronic devices in the vehicle, and generally, it can start the vehicle engine, maintain the electrical system in the vehicle, and provide the necessary power during driving.

[0063] The auxiliary battery for the vehicle can be a device that supplies power separately from the main battery for the vehicle so that the driving video recording system 1000 continues to operate when the vehicle engine is stopped.

[0064] On one hand, the camera connector 130 and the main body connector 230 can be connected to each other via a cable connecting them. The camera connector 131 and the main body connector 230 can be connected to each other via a coaxial cable. However, it is not limited thereto, and the signal (power signal and data signal) lines of the photographing unit 110 that captures video and the signal (power signal and data signal) lines of the event sensing unit 120 that senses events in the parking recording mode can be configured separately from each other, and the control unit 220 can separate and control each line. In the present invention, an embodiment in which the camera connector 130 and the main body connector 230 are connected via a coaxial cable will be described in detail.

[0065] In an exemplary embodiment, the camera 100 can further include a conversion unit 115, and the conversion unit 115 can be composed of at least one or more of a voltage conversion unit 150, a current conversion unit 160, a transmission power supply unit 170, and a transmission power conversion unit 180. Here, the conversion unit 115 can also be a configuration included in the event sensing unit 120. Alternatively, it may not be a configuration included in the event sensing unit 120 but a configuration separately provided in the camera 100.

[0066] The voltage conversion unit 150 can be included in the event sensing unit 120 and may also be referred to as a DC-DC converter 122. The voltage conversion unit 150 is a device that converts a direct current (DC) voltage into another direct current (DC) voltage, and can convert the input direct current voltage into a lower or higher direct current voltage to supply power required for the event sensing module 121.

[0067] The camera 100 according to an exemplary embodiment of the present invention can further include a voltage control unit 151, a current control unit 161, and a voltage / current control unit 165.

[0068] The voltage control unit 151 can be configured to adjust the magnitude or intensity of the voltage of the power signal transferred sequentially via a POC filter 113, a DC / DC converter 122, and an event sensing module 121, which will be described later. The power signal having a voltage whose magnitude or intensity is adjusted by the voltage control unit 151 can be merged into the data transfer signal of a serializer 114, which will be described later, and transmitted to the main body 200. In an exemplary embodiment, the voltage control unit 151 can be controlled to adjust the normal voltage in the parking recording mode based on an interrupt signal generated from at least one of the impact event sensing sensor and the motion event sensing sensor described later.

[0069] For example, when the occurrence of an impact or motion is sensed by at least one of the impact event sensing sensor and the motion event sensing sensor, the voltage control unit 151 can operate to increase or decrease the voltage.

[0070] In one embodiment, the voltage control unit 151 can be composed of transistors. In this case, if the occurrence of an impact or motion is not sensed, the control unit 220 turns on the power supply to the transistors by the power supply unit 240. When the occurrence of an impact or motion is sensed, the control unit 220 turns off the power supply to the transistors by the power supply unit 240 and can control to decrease the normal voltage in the parking recording mode.

[0071] In another embodiment, the voltage control unit 151 can be configured by a DC / DC converter. In this case, when an impact or motion is detected, the control unit 220 can control the DC / DC converter to increase the normal voltage in the parking recording mode. Here, the DC / DC converter constituting the voltage control unit 151 may be provided as the same type of converter as the DC / DC converter 122 constituting the voltage conversion unit 150, or may be provided as a different type of converter. The main body 200 can further include a voltage sensing unit 250 that senses a voltage change of the camera 100. When the voltage change is sensed by the voltage sensing unit 250, the control unit 220 can control the imaging unit 110 and the image processing unit 210 to turn on the power supply, respectively.

[0072] The current control unit 161 can be a configuration for adjusting the magnitude or intensity of the current of the power signal transferred sequentially via the POC filter 113, the DC / DC converter 122, and the event sensing module 121, which will be described later. The power signal having a current whose magnitude or intensity is adjusted by the current control unit 161 can be merged into the data transfer signal of the serializer 114, which will be described later, and transmitted to the main body 200. In an exemplary embodiment, the current control unit 161 can be controlled to adjust the normal current in the parking recording mode based on an interrupt signal generated from at least one of the impact event sensing sensor and the motion event sensing sensor.

[0073] The current control unit 161 is included in the event sensing unit 120 and can be provided to convert the current transmitted to the main body based on an interrupt signal generated from at least one of the impact event sensing sensor and the motion event sensing sensor.

[0074] When the occurrence of an impact or motion is detected by at least one of the impact event detection sensor and the motion event detection sensor, the current control unit 161 can operate to increase or decrease the current.

[0075] In one embodiment, the current control unit 161 can be composed of a FET (Field-Effect Transistor). If the occurrence of an impact or motion is not detected, the control unit 220 turns on the power supply to the FET by the power supply unit 240. When the occurrence of an impact or motion is detected, the control unit turns off the power supply to the FET by the power supply unit, and can control to decrease the normal current in the parking recording mode.

[0076] In another embodiment, the current control unit 161 can be composed of a load circuit. When the occurrence of an impact or motion is detected, the control unit can control to increase the normal current in the parking recording mode by activating the load circuit.

[0077] On the one hand, the voltage / current control unit 165 can be configured to adjust the magnitude or intensity of the voltage and / or current of the power signal transferred sequentially via the POC filter 113, the DC / DC converter 122, and the event sensing module 121 described later. The power signal having the voltage and / or current whose magnitude or intensity has been adjusted by the voltage / current control unit 165 can be merged into the data transfer signal of the serializer 114 described later and transmitted to the main body 200. Here, the voltage / current control unit 165 can be configured by merging the above-described voltage control unit 151 and current control unit 161. However, the concept of the present invention is not necessarily limited thereto, and it may be provided as one configuration for controlling both voltage and current. In one embodiment, the power signal having the voltage and / or current whose magnitude or intensity has been adjusted by the voltage / current control unit 165 can be applied as a trigger for changing the voltage of the status pin 270. In an exemplary embodiment, the voltage / current control unit 165 is controlled to adjust at least one of the normal voltage and the normal current in the parking recording mode based on an interrupt signal generated from at least one of the impact event sensing sensor and the motion event sensing sensor.

[0078] The main body 200 can further include a current sensing unit 260 for sensing a current change of the camera 100. When the control unit 220 senses a current change by the current sensing unit 260, the control unit 220 can control the imaging unit 110 and the image processing unit 210 to turn on the power supply, respectively.

[0079] The transmission power supply unit 170 can be configured to output transmission power to the main body connector according to a value preset in the parking recording mode, and the transmission power conversion unit 180 can be configured to change the period or amplitude of the transmission power. Here, the transmission power supply unit 170 and the transmission power conversion unit 180 may be provided separately from the current conversion unit 160, or may be included in the current conversion unit 160.

[0080] When the control unit 220 senses the occurrence of an impact or motion, it can control the transmission power conversion unit 180 to increase or decrease the period or amplitude of the transmission power, thereby generating a peak current in the parking recording mode.

[0081] Here, the current sensing unit 260 included in the main body 200 can be operated to further sense the generation of the peak current. When the control unit 220 senses the generation of the peak current by the current sensing unit 260, it can control the imaging unit 110 and the image processing unit 210 to turn on the power supply respectively.

[0082] That is, when the voltage / current control unit 165 senses the occurrence of an impact or motion by at least one of the impact event sensing sensor and the motion event sensing sensor, it can operate to increase or decrease at least one of the normal voltage and the normal current.

[0083] In this case, the camera 100 can further include a state pin 270 whose voltage changes according to the change in the state of the power supply line supplied by the power supply unit 240. The main body 200 can further include a state pin voltage confirmation unit 280 for sensing the voltage of the state pin 270, but the concept of the present invention is not necessarily limited thereto. That is, the state pin 270 may be a configuration included in the main body 200 instead of a configuration included in the camera 100.

[0084] When the state pin 270 senses that at least one of the voltage and current received from the camera 100 is smaller or larger than a preset value, it can operate to increase or decrease the voltage. When the control unit 220 senses the voltage change of the state pin 270 through the state pin voltage confirmation unit 280, it can control the imaging unit 110 and the image processing unit 210 to turn on the power supply respectively.

[0085] The signal line according to the present invention will be described later with reference to FIGS. 3 to 6.

[0086] FIG. 2 is a block diagram specifically showing a traveling 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 realized to be connected to the main body 200. Here, each of the plurality of cameras 100-1, 100-2,... 100-n may include all or part of a front camera, a rear camera for shooting the rear, a side camera for shooting the left and right sides, a camera for shooting the face of the vehicle driver, and a camera for shooting the interior of the vehicle. The video shot by each shooting unit 110 can be transferred to the main body 200. The event sensed by each event sensing unit 120 can be transferred to the main body 200. Here, the plurality of cameras 100-1, 100-2,... 100-n and the main body 200 can communicate in a serial transfer method.

[0087] FIGS. 3 to 6 are block diagrams specifically showing a traveling video recording system according to an embodiment of the present invention.

[0088] Referring to FIG. 3, the shooting unit 110 may include a lens unit 111, an image sensor 112, an image signal processor ISP, a serializer 114, and the like. The lens unit 111 can perform a function of condensing an optical signal, and the optical signal transmitted through the lens unit 111 reaches the imaging region of the image sensor 112 to form an optical image. Here, as the image sensor 112, a CCD (Charge Coupled Device), a CIS (Complementary Metal Oxide Semiconductor Image Sensor), or a high-speed image sensor that converts an optical signal into an electrical signal can be used.

[0089] The image sensor 112 can include an Image Signal Processor (ISP) that processes the raw video data collected from the image sensor. The image signal processing unit can perform functions such as noise removal, white balance adjustment, gamma correction, color filter correction, and tone mapping.

[0090] The serializer 114 functions to convert a plurality of parallel data into one serial data. The serializer 114 can transfer the converted data to the deserializer 211 of the image processing unit 210 of the main body 200 via the first camera connector 131 of the camera connector 130, the first main body connector 231 of the main body connector 230, and a single cable connecting them.

[0091] The imaging unit 110 can further include a POC (Power Over Coax) filter, and when transmitting power and data signals simultaneously via a single coaxial cable, the imaging unit 110 can function to separate them so that the power supply and data signals do not mix. That is, when supplying power to the imaging unit 110 and transferring a high-resolution video signal via the coaxial cable, the power signal and the data signal may interfere, but the POC filter can prevent this.

[0092] Also, the imaging unit 110 can include a PMIC (Power Management IC), and the PMIC can be a power management integrated circuit that efficiently supplies and manages power to the imaging unit 110.

[0093] In addition, the photographing unit 110 can further include an indicator 118, and the indicator 118 can mean an LED display lamp or a notification device that visually notifies the user of the state and operation of the driving video recording system 1000 described later. As an example, the indicator 118 can provide information such as whether the driving video recording system 1000 is operating normally, whether recording is being performed well, or whether an error has occurred, and can help the user easily grasp the state of the driving video recording system 1000. The indicator 118 can provide notification information to the user through various hues and blinking patterns, etc.

[0094] The event sensing unit 120 can include all or part of the event sensing module 121, the DC-DC converter 122, and the voltage control unit 151.

[0095] The event sensing module 121 can include a shock event sensing module and a motion event sensing module. The shock event sensing module can be realized as a G-Sensor for sensing shock and acceleration, and the motion event sensing module can be realized as a radar sensor.

[0096] The voltage control unit 151 can be a configuration for adjusting the magnitude or intensity of the voltage of the power supply signal transferred in sequence through the POC filter 113, the DC / DC converter 122, and the event sensing module 121. The power supply signal having a voltage whose magnitude or intensity is adjusted by the voltage control unit 151 can be merged into the data transfer signal of the serializer 114 described later and transmitted to the main body 200. In an exemplary embodiment, the voltage control unit 151 can be controlled to adjust the normal voltage in the parking recording mode based on an interrupt signal generated from at least one of the shock event sensing sensor and the motion event sensing sensor.

[0097] Here, the main body 200 can further include a voltage sensing unit 250 that senses the voltage change of the camera 100. When the voltage change is sensed by the voltage sensing unit 250, the control unit 220 can control the imaging unit 110 and the image processing unit 210 to turn on the power supply, respectively.

[0098] The main body 200 can further include a deserializer 211 and an image processing unit 210.

[0099] The deserializer 211 can convert the serialized data back into the first parallel data and perform the function of restoring the data to its original form.

[0100] In an exemplary embodiment, the voltage sensing unit 250 can be provided to sense the voltage before the signal line received from the first main body connector 231 is transmitted to the deserializer 211. Thereby, the voltage in a state where the signal line is not adjusted or processed by other components can be accurately sensed.

[0101] The image processing unit 210 is a processor that processes and analyzes images, and can further process the basic video data processed by the image signal processing unit (ISP) through more complex operations. As an example, the image processing unit 210 can perform image recognition based on AI, object tracking, etc.

[0102] For example, the image processing unit 210 can analyze the captured video of the imaging unit 110 and determine whether the above-mentioned advanced driving assistance system (ADAS) is required.

[0103] On the one hand, according to the present invention, the signal (power signal and data signal) lines of the imaging unit 110 that captures videos and the signal (power signal and data signal) lines of the event sensing unit 120 that senses events in the parking recording mode can be merged into an integrated configuration, and the control unit 220 can merge and control the signal line of the imaging unit 110 and the signal line of the event sensing unit 120 into an integrated line.

[0104] Before the main body 200 transmits the integrated signal line received from the first main body connector 231 included in the main body connector 230 to the parallel converter 211, the main body 200 can further include a filter 242 that performs a function of separating the power supply and data signals included in the integrated signal line so that they do not mix. That is, when receiving a power signal from the imaging unit 110 via the coaxial cable and receiving a high-resolution video signal together, the power signal and the data signal may interfere with each other, but the filter 242 can prevent this.

[0105] On the other hand, the power supply unit 240 of the main body 200 can include a power line supply unit 241, and the power line supply unit 241 can supply power for the operations of the imaging unit 110, the image processing unit 210, and the filter 242.

[0106] The on / off of the power supply of such a power line supply unit 241 can be controlled by the control unit 220.

[0107] On the other hand, the camera connector 130 is formed on the camera 100 side and can include a first camera connector 131 that interfaces data communication between the imaging unit 110 and the image processing unit 210 and interfaces power supply between the imaging unit 110 and the power line supply unit 241.

[0108] Also, the main body connector 230 is formed on the main body 200 side and can include a first main body connector 231 that interfaces data communication between the imaging unit 110 and the image processing unit 210 and interfaces power supply between the imaging unit 110 and the power line supply unit 241.

[0109] For the "Conn." of the first camera connector 131 and the first main body connector 231, a single-pin FAKRA to which the POC (Power Over Coax) method is applied can be used, whereby data signals and power signals can be transmitted and received between the first camera connector 131 and the first main body connector 231.

[0110] On the other hand, the camera connector 130 and the main body connector 230 can be connected to each other via an integrated cable that connects them.

[0111] On the other hand, the control unit 220 can control the overall operation of the traveling video recording system 1000. Specifically, the control unit 220 can set the recording mode of the traveling video recording system 1000 based on, for example, whether the vehicle has started, the measurement result of the vehicle battery voltage, the necessity of the vehicle driving assistance function, and the detection result of the event detection unit 120. Here, the recording mode of the traveling video recording system 1000 can include a traveling recording mode and a parking recording mode.

[0112] In addition, the control unit 220 can control the power supply of the power supply unit 240 according to the recording mode of the traveling video recording system 1000. Specifically, the control unit 220 can control the power supply of the power supply unit 240 so that the current consumption of the traveling video recording system 1000 is minimized in the parking recording mode. That is, the control unit 220 can minimize the battery consumption of the vehicle by operating the traveling video recording system 1000 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.

[0113] Hereinafter, with reference to FIGS. 4 to 6, a driving video recording system according to an exemplary embodiment of the present invention will be described. The video recording system described with reference to FIGS. 4 to 6 is substantially the same or similar to the video recording system described with reference to FIG. 3, except for some configurations. Therefore, the same reference numerals are assigned to the same configurations, and repeated descriptions thereof are omitted.

[0114] Referring to FIG. 4, the event sensing unit 120 can include all or part of the event sensing module 121, the DC-DC converter 122, and the current control unit 161.

[0115] The current control unit 161 can be a configuration for adjusting the magnitude or intensity of the current of the power supply signal transferred sequentially via the POC filter 113, the DC / DC converter 122, and the event sensing module 121, which will be described later. The power supply signal having a current whose magnitude or intensity is adjusted by the current control unit 161 can be merged into the data transfer signal of the serializer 114, which will be described later, and transmitted to the main body 200. In an exemplary embodiment, the current control unit 161 can be controlled to adjust the normal current in the parking recording mode based on an interrupt signal generated from at least one of the impact event sensing sensor and the motion event sensing sensor.

[0116] Here, the main body 200 can include a current sensing unit 260 that senses a current change of the camera 100. When the current change is sensed by the current sensing unit 260, the control unit 220 can control the imaging unit 110 and the image processing unit 210 to turn on the power supply, respectively.

[0117] In an exemplary embodiment, the current sensing unit 260 can be provided to sense the current of the power signal supplied to or received by the filter 242 from the power line supply unit 241. That is, in the parking recording mode, the power line supply unit 241 maintains a state of supplying power only to the event sensing unit 120 while the connection between the photographing unit 110, the parallel converter 211 of the main body 200, and the image processing unit 210 is disconnected. Here, when an interrupt signal is generated due to the occurrence of an event by the event sensing unit 120, a power signal having a current whose magnitude or intensity is adjusted by the current control unit 161 is sensed by the current sensing unit 260. Based on the mechanism as described above, when the current sensing unit 260 senses a change in the current of the signal line, the control unit 220 can control the photographing unit 110 and the image processing unit 210 to turn on the power supply, respectively.

[0118] Referring to FIG. 5, the event sensing unit 120 includes an event sensing module 121 and a DC-DC converter 122, does not include the voltage control unit 151 or the current control unit 161, and may further include the transmission power supply unit 170 and the transmission power conversion unit 180 described with reference to FIG. 1.

[0119] Here, the transmission power supply unit 170 can be configured to output the transmission power to the main body connector according to a preset value in the parking recording mode, and the transmission power conversion unit 180 can be configured to change the period or amplitude of the transmission power.

[0120] When the control unit 220 senses the occurrence of an impact or motion, it can control the transmission power conversion unit 180 to increase or decrease the period or amplitude of the transmission power so as to generate a peak current in the parking recording mode.

[0121] Although not shown, the transmission power supply unit 170 and the transmission power conversion unit 180 can be configurations included in the event sensing unit 120, more specifically, configurations included in the event sensing module 121.

[0122] Here, the current sensing unit 260 included in the main body 200 can be operated to further sense the generation of the peak current. When the generation of the peak current is sensed by the current sensing unit 260, the control unit 220 can control the imaging unit 110 and the image processing unit 210 to turn on the power supply, respectively.

[0123] In an exemplary embodiment, the current sensing unit 260 can be provided to sense the peak current of the power signal supplied to or received by the filter 242 from the power line supply unit 241. That is, in the parking recording mode, the power line supply unit 241 maintains a state of supplying power only to the event sensing unit 120 while the connection between the imaging unit 110, the parallel converter 211 of the main body 200, and the image processing unit 210 is disconnected. Here, when an interrupt signal due to an event is generated by the event sensing unit 120, the transmission power supply unit 170 generates TX Power, and the transmission power conversion unit 180 is controlled to change the period or amplitude of the transmission power. As a result, the transmission power having the changed period or amplitude causes the generation of the peak current, and the current sensing unit 260 can be operated to sense the generation of the peak current.

[0124] Based on the mechanism as described above, when the generation of the peak current is sensed by the current sensing unit 260, the control unit 220 can control the imaging unit 110 and the image processing unit 210 to turn on the power supply, respectively.

[0125] Referring to FIG. 6, the event sensing unit 120 can include all or part of the event sensing module 121, the DC-DC converter 122, and the voltage / current control unit 165.

[0126] The voltage / current control unit 165 can be configured to adjust the magnitude or intensity of the voltage and / or current of the power signal transferred sequentially via the POC filter 113, the DC / DC converter 122, and the event sensing module 121. The power signal having the voltage and / or current whose magnitude or intensity is adjusted by the voltage / current control unit 165 can be merged into the data transfer signal of the serializer 114 and transmitted to the main body 200. The power signal having the voltage and / or current whose magnitude or intensity is adjusted by the voltage / current control unit 165 can be applied as a trigger for changing the voltage of the status pin 270.

[0127] Here, the main body 200 can further include a status pin voltage confirmation unit 280 that senses the voltage change of the status pin 270. When the control unit 220 senses a voltage change by the status pin voltage confirmation unit 280, the control unit 220 can control the imaging unit 110 and the image processing unit 210 to turn on the power supply, respectively.

[0128] FIGS. 7 to 8 are diagrams showing an embodiment of a traveling video recording system according to an embodiment of the present invention. Referring to FIG. 7, the camera 100 and the main body 200 can be physically configured separately from each other. Also, the camera 100 and the main body 200 can be realized to be removable from each other.

[0129] The main body 200 can include, in addition to the above, an image processing unit 210, a control unit 220, a main body connector 230, and a power supply unit 240, as well as having a frame function for installing the traveling video recording system 1000 in a vehicle.

[0130] Also, the camera 100 can be removably installed on the main body 200, and the camera 100 can include an imaging unit 110, an event sensing unit 120, and a camera connector 130.

[0131] Referring to FIG. 8, in a region of the main body 200, a first input unit 301 that receives power supply from the vehicle main battery and a second input unit 302 that supplies power from the vehicle auxiliary battery can be included. The power input by the first input unit 301 and the second input unit 302 can be supplied to the power supply unit 240 inside the main body 200.

[0132] FIGS. 9 to 16 are diagrams for explaining a method for reducing the consumption current according to an exemplary embodiment of the present invention. Specifically, FIGS. 9 and 10 are a flowchart and a conceptual diagram for explaining a method for reducing the consumption current based on a change in voltage due to the occurrence of an event, respectively. FIGS. 11 and 12 are a flowchart and a conceptual diagram for explaining a method for reducing the consumption current based on a change in current due to the occurrence of an event, respectively. FIGS. 13 and 14 are a flowchart and a conceptual diagram for explaining a method for reducing the consumption current based on a change in transmission power due to the occurrence of an event, respectively. FIGS. 15 and 16 are a flowchart and a conceptual diagram for explaining a method for reducing the consumption current based on a change in the voltage of the status pin due to the occurrence of an event, respectively.

[0133] Referring to FIG. 9, the method for reducing the consumption current according to an exemplary embodiment of the present invention can include a step of executing the parking recording mode (S10), a step of detecting the presence or absence of an event (S11), a step of detecting a change in voltage due to the generation of an interrupt signal (S12), a step of waking up and operating the imaging unit 110 and the image processing unit 210 (S13), a step of confirming the completion of the imaging operation (S14), and a step of cutting off the power supply to all components other than the event detection unit 120 and the control unit 220 (S15).

[0134] The parking recording mode execution step (S10) can be a mode that is performed when the vehicle's running stops and the engine is stopped. The control unit 220 can control the power supply of the power supply unit 240 so that the current consumption of the driving video recording system 1000 is minimized in the parking recording mode. As an example, the control unit 220 can control the power supply unit 240 so that in the parking recording mode, the power supply to the imaging unit 110 is turned off and the power supply to the event sensing unit 120 is turned on.

[0135] The step of detecting the presence or absence of an event (S11) can be performed by the event sensing unit 120. For example, it can be performed by a shock event sensing sensor that senses the impact applied to the vehicle and / or a motion event sensing sensor that senses an object such as a person, vehicle, or animal approaching the vehicle.

[0136] In the step of detecting the presence or absence of an event (S11), when an impact or movement is detected, an interrupt signal is generated by the event sensing unit 120. Based on the generation of the interrupt signal, a change in voltage can occur by the voltage conversion unit 150, and the change in voltage can be sensed by the voltage sensing unit 250 of the main body 200 (S12). If no impact or movement is detected in the step of detecting the presence or absence of an event (S11), the parking recording mode (S10) can be continuously maintained.

[0137] When the voltage sensing unit 250 senses a change in voltage, a step can be performed in which the control unit 220 wakes up (Wake-up) and operates the imaging unit 110 and the image processing unit 210 (S13).

[0138] Next, a step can be performed to confirm whether the shooting operations of the imaging unit 110 and the image processing unit 210 are completed (S14). The operation completion confirmation step (S14) can be performed by sensing that the generation of further interrupt signals from the shock event sensing sensor and the motion event sensing sensor is interrupted.

[0139] When the photographing operation is completed, by also cutting off the power supply of all components other than the event detection unit 120 and the control unit 220 (S15), the process of reducing the current consumption can be completed.

[0140] FIG. 7 illustrates the process in which the normal voltage increases or decreases by the voltage conversion unit 150, and the process in which the voltage sensing unit 250 senses the change in the voltage to sense motion or movement (or impact).

[0141] In one embodiment, when the voltage conversion unit 150 is composed of a transistor, when the occurrence of an impact or motion is detected, the operation of the transistor becomes OFF, and the normal voltage in the parking recording mode can be decreased.

[0142] In another embodiment, when the voltage conversion unit 150 is composed of a DC / DC converter, when the occurrence of an impact or motion is detected, the DC / DC converter boosts the voltage, and the normal voltage in the parking recording mode can be increased.

[0143] Referring to FIG. 8, the method for reducing the current consumption according to an exemplary embodiment of the present invention may include a parking recording mode execution step (S20), an event occurrence detection step (S21), a step of detecting a change in current due to the generation of an interrupt signal (S22), a wake-up and operation step of the photographing unit 110 and the image processing unit 210 (S23), a step of confirming the completion of the photographing operation (S24), and a step of cutting off the power supply of all components other than the event detection unit 120 and the control unit 220 (S25). Here, the remaining steps other than the current change detection step (S22) are substantially the same or similar to the method described with reference to FIG. 9, and repeated descriptions of the same configuration are omitted.

[0144] When an impact or movement is detected in the event occurrence detection step (S21), an interrupt signal is generated by the event detection unit 120. Based on the generation of the interrupt signal, a change in current may occur by the current conversion unit 160, and the change in current can be detected by the current detection unit 260 of the main body 200 (S22). When no impact or movement is detected in the event occurrence detection step (S11), the parking recording mode (S10) can be continuously maintained.

[0145] When the current detection unit 260 detects a change in voltage, a step of waking up and operating the imaging unit 110 and the image processing unit 210 by the control unit 220 can be performed (S23).

[0146] FIG. 9 illustrates a process in which the normal current increases or decreases by the current conversion unit 160, and a process in which the current detection unit 260 detects the change in current to detect motion or movement (or impact).

[0147] In one embodiment, when the current conversion unit 160 is composed of a FET (Field-Effect Transistor), when the occurrence of an impact or motion is detected, the operation of the FET becomes OFF, and the normal current in the parking recording mode can be decreased.

[0148] In another embodiment, when the current conversion unit 160 is composed of a load circuit, when the occurrence of an impact or motion is detected, the normal voltage in the parking recording mode can be increased by activating the load circuit.

[0149] Referring to FIG. 10, a method for reducing power consumption according to an exemplary embodiment of the present invention may include a parking recording mode execution step (S30), an event occurrence detection step (S31), a step of detecting a change in transmission power due to the generation of an interrupt signal (S32), a wake-up and operation step of the imaging unit 110 and the image processing unit 210 (S33), a completion confirmation step of the shooting operation (S34), and a step of cutting off the power supply of all components other than the event detection unit 120 and the control unit 220 (S35). Here, the remaining steps other than the transmission power change detection step (S32) are substantially the same or similar to the methods described with reference to FIGS. 9 and 11, and repeated descriptions of the same configurations are omitted.

[0150] When an impact or movement is detected in the event occurrence detection step (S31), an interrupt signal is generated by the event detection unit 120, and based on the generation of the interrupt signal, a change in transmission power may occur by the current conversion unit 160, and the change in transmission power can be detected by the current detection unit 260 of the main body 200 (S32). Specifically, the change in transmission power can be performed by the transmission power conversion unit 180 changing the period or amplitude of the transmission power, thereby generating a peak current. On the other hand, when no impact or movement is detected in the event occurrence detection step (S31), the parking recording mode (S30) can be continuously maintained.

[0151] When the current detection unit 260 detects a change in transmission power, that is, the generation of a peak current, the control unit 220 can perform a step of waking up (Wake-up) and operating the imaging unit 110 and the image processing unit 210 (S33).

[0152] FIG. 11 illustrates the process in which the period or amplitude of the transmission power changes by the current conversion unit 160 or the transmission power conversion unit 180, and the process in which the current detection unit 260 detects a peak current generated by the change in the period or amplitude of the transmission power to detect motion or movement (or impact).

[0153] Referring to FIG. 12, the method for reducing the consumption current according to an exemplary embodiment of the present invention may include a parking recording mode execution step (S40), an event occurrence detection step (S41), a step of detecting a change in a status pin due to the generation of an interrupt signal (S42), a wake-up and operation step of the photographing unit 110 and the image processing unit 210 (S43), a completion confirmation step of the photographing operation (S44), and a power supply cut-off step of all components other than the event detection unit 120 and the control unit 220 (S45). Here, the remaining steps other than the step of detecting the change in the status pin (S42) are substantially the same or similar to the methods described with reference to FIGS. 9, 11, and 13, and repeated descriptions of the same configuration are omitted.

[0154] When an impact or movement is detected in the event occurrence detection step (S41), an interrupt signal is generated by the event detection unit 120, and based on the generation of the interrupt signal, a change in voltage or current may occur by the voltage / current conversion units 150 and 160, and the change in voltage or current may cause a voltage change in the status pin 270 provided in the main body 200. The change in the voltage of the status pin 270 can be detected by the status pin voltage confirmation unit 280 of the main body 200 (S42).

[0155] When the status pin voltage confirmation unit 280 detects a voltage change in the status pin 270, a step of waking up (Wake-up) and operating the photographing unit 110 and the image processing unit 210 can be performed by the control unit 220 (S43).

[0156] FIG. 13 illustrates a process in which the normal voltage and the normal current change by the voltage / current conversion units 150 and 160, and a process of detecting motion or movement (or impact) by detecting a voltage decrease in the status pin 270 based on the change in the normal voltage and the normal current.

In various embodiments, each element can be connected via various interfaces. For example, the sensor data sensed and output by the sensor 803 can be fed to the image pre-processor 805. The sensor data processed by the image pre-processor 805 can be fed to the deep learning network 807 run by the AI processor 809. The output of the deep learning network 807 run by the AI processor 809 can be fed to the vehicle control module 811. The intermediate result of the deep learning network 807 run by the AI processor 809 can be fed to the AI processor 809. In various embodiments, the network interface 813 transmits autonomous driving route information and / or autonomous driving control commands for the autonomous driving of the vehicle to the internal block configuration by communicating with electronic devices in the vehicle. In one embodiment, the network interface 813 can be used to transfer the sensor data acquired by the sensor 803 to an external server.

[0170] According to one embodiment, the autonomous driving system 800 illustrated in FIG. 17 may be composed of electronic devices of a vehicle. According to one 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 can be controlled to input autonomous driving cancellation event-related information as training set data of a deep learning network, thereby controlling the autonomous driving software of the vehicle to learn.

[0171] FIGS. 18 and 19 are diagrams illustrating an example of a block diagram showing an autonomous driving mobile body according to one embodiment. Referring to FIG. 18, the autonomous driving mobile body 900 according to this embodiment can include a control device 1000, sensing modules 904a, 904b, 904c, 904d, an engine 906, and a user interface 908.

[0172] The autonomous driving mobile body 900 can be provided with an autonomous driving mode or a manual mode. As an example, it can be switched from the manual mode to the autonomous driving mode or from the autonomous driving mode to the manual mode in response to user input received via the user interface 908.

[0173] When the mobile body 900 is operating in the autonomous driving mode, the autonomous driving mobile body 900 can operate under the control of the control device 1000.

[0174] In this embodiment, the control device 1000 can 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.

[0175] Here, the object detection device 1040 can perform all or part of the functions of a distance measurement device (for example, the electronic device 101).

[0176] That is, in this embodiment, the object detection device 1040 is a device for detecting an object located outside the moving body 900, and the object detection device 1040 can detect an object located outside the moving body 900 and generate object information based on the detection result.

[0177] The object information can include information on the presence or absence of an object, the position information of the object, the distance information between the moving body and the object, and the relative speed information between the moving body and the object.

[0178] The object can include various objects located outside the moving body 900 such as a lane, other vehicles, pedestrians, traffic signals, light, roads, structures, speed bumps, terrain objects, animals, etc. Here, the traffic signal can be a concept including traffic lights, traffic signs, patterns or texts illustrated on the road surface. Also, the light can be light generated from a lamp provided on another vehicle, light generated from a street lamp, or sunlight.

[0179] Also, the structure can be an object located around the road and fixed to the ground. For example, the structure can include street lamps, street trees, buildings, utility poles, signal lights, bridges. The terrain object can include mountains, hills, etc.

[0180] Such an object detection device 1040 can include a camera module. The controller 1020 can extract object information from an external image captured by the camera module and cause the controller 1020 to process information related thereto.

[0181] In addition, the object detection device 1040 can 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 can be used, and these devices can operate selectively or simultaneously as needed to enable more precise sensing.

[0182] On the other hand, the distance measurement device according to an embodiment of the present invention can calculate the distance between the autonomous mobile body 900 and an object and control the operation of the mobile body based on the calculated distance in cooperation with the control device 1000 of the autonomous mobile body 900.

[0183] As an example, when there is a possibility of a collision according to the distance between the autonomous mobile body 900 and an object, the autonomous mobile body 900 can control the brakes to reduce speed or stop. As another example, when the object is a moving object, the autonomous mobile body 900 can control the traveling speed of the autonomous mobile body 900 to maintain a distance of a predetermined distance or more from the object.

[0184] The distance measurement device according to such an embodiment of the present invention can be configured by a module within the control device 1000 of the autonomous mobile body 900. That is, the memory 1022 and the processor 1024 of the control device 1000 can implement the collision prevention method according to the present invention in software.

[0185] In addition, the sensor 1010 can be connected to the sensing modules 904a, 904b, 904c, and 904d for sensing the internal / external environment of the moving object, and can obtain various sensing information. 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 sensing sensor, a heading sensor, a gyro sensor, a position module, a forward / backward movement sensor of the moving object, a battery sensor, a fuel sensor, a tire sensor, a steering sensor by handle rotation, an internal temperature sensor of the moving object, an internal humidity sensor of the moving object, an ultrasonic sensor, an illuminance sensor, an acceleration pedal position sensor, a brake pedal position sensor, etc.

[0186] Thereby, the sensor 1010 can obtain sensing signals regarding the attitude information of the moving object, the collision information of the moving object, the direction information of the moving object, the position information (GPS information) of the moving object, the angle information of the moving object, the speed information of the moving object, the acceleration information of the moving object, the gradient information of the moving object, the forward / backward movement information of the moving object, the battery information, the fuel information, the tire information, the lamp information of the moving object, the internal temperature information of the moving object, the internal humidity information of the moving object, the rotation angle of the steering wheel, the external illuminance of the moving object, the pressure applied to the acceleration pedal, the pressure applied to the brake pedal, etc.

[0187] In addition, the sensor 1010 can further include an acceleration pedal sensor, a pressure sensor, an engine speed sensor, an air flow sensor (AFS), an intake air temperature sensor (ATS), a water temperature sensor (WTS), a throttle position sensor (TPS), a TDC sensor, a crank angle sensor (CAS), etc.

[0188] In this way, the sensor 1010 can generate the state information of the moving object based on the sensing data.

[0189] The wireless communication device 1030 is configured to realize wireless communication between the autonomous driving vehicle 900. For example, the autonomous driving vehicle 900 can communicate with a user's mobile phone, another wireless communication device 1030, another vehicle, 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 to this.

[0190] Also, in the present embodiment, the autonomous driving vehicle 900 can also realize communication between vehicles by the wireless communication device 1030. That is, the wireless communication device 1030 can communicate with other vehicles and other vehicles on the road by vehicle-to-vehicle (V2V) communication. The autonomous driving vehicle 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 vehicles or receive requests. For example, the wireless communication device 1030 can perform V2V communication with a dedicated short-range communication (DSRC) device or a Cellular-V2V (C-V2V) device. In addition to vehicle-to-vehicle communication, communication between a vehicle and other things (for example, an electronic device carried by a pedestrian, etc.) (V2X, Vehicle to Everything communication) can also be realized by the wireless communication device 1030.

[0191] In this embodiment, the controller 1020 is a unit that controls the overall operation of each unit within the moving body 900, and can be configured during manufacturing or additionally configured after manufacturing for the performance of the autonomous driving function by the manufacturer of the moving body. Alternatively, the configuration for the continuous performance of additional functions can be included by upgrading the controller 1020 configured during manufacturing. Such a controller 1020 may also be referred to as an ECU (Electronic Control Unit).

[0192] The controller 1020 can collect various data from the connected sensor 1010, object detection device 1040, communication device 1030, etc., and based on the collected data, transmit a control signal to the sensor 1010, engine 906, user interface 908, communication device 1030, object detection device 1040 included as other components within the moving body. Also, although not shown, a control signal can also be transmitted to an acceleration device, braking system, steering device, or navigation device related to the driving of the moving body.

[0193] In this embodiment, the controller 1020 can control the engine 906. For example, when the autonomous driving moving body 900 senses the speed limit of the road during driving, the controller 1020 can control the engine 906 so that the driving speed does not exceed the speed limit, or control the engine 906 to accelerate the driving speed of the autonomous driving moving body 900 within a range not exceeding the speed limit.

[0194] Also, while the autonomous mobile body 900 is in motion, if the controller 1020 determines that the autonomous mobile body 900 is approaching or departing from a lane, it can control the engine 906 to control the movement of the mobile body according to whether such lane approach and departure are due to normal driving conditions or other driving conditions. Specifically, the autonomous 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 determines whether the autonomous mobile body 900 is approaching or departing from a lane. For example, if it is determined that the autonomous mobile body 900 is approaching or departing from a lane, it can be determined whether such driving is due to accurate driving conditions or other driving conditions. Here, an example of normal driving conditions can be a situation where a lane change of the mobile body is necessary. Also, an example of other driving conditions can be a situation where a lane change of the mobile body is not necessary. For example, if the controller 1020 determines that the autonomous mobile body 900 is approaching or departing from a lane in a situation where a lane change of the mobile body is not necessary, it can control the movement of the autonomous mobile body 900 so that the autonomous mobile body 900 does not depart from the lane and travels normally with the mobile body.

[0195] When there is another mobile body or an obstacle in front of the mobile body, the engine 906 or the braking system can be controlled to decelerate the moving mobile body, and in addition to the speed, the trajectory, the travel route, and the steering angle can also be controlled. Alternatively, the controller 1020 can generate necessary control signals according to the recognition information of other external environments such as the travel lane and the travel signal of the mobile body, and control the movement of the mobile body.

[0196] In addition to generating its own control signals, the controller 1020 can also communicate with surrounding mobile bodies or a central server, and transfer commands for controlling peripheral devices according to the received information, so as to control the movement of the mobile body.

[0197] In addition, when the position of the camera module 1050 is changed or the viewing angle is changed, the controller 1020 may generate a control signal to control the calibration of the camera module 1050 in order to prevent the accurate recognition of the moving object or the lane according to the present embodiment from being difficult. Therefore, in the present embodiment, the controller 1020 causes the camera module 1050 to generate a calibration control signal, so that even if the mounting position of the camera module 1050 is changed due to vibrations or impacts generated according to the movement of the autonomous driving vehicle 900, the normal mounting position, direction, viewing angle, etc. of the camera module 1050 can be continuously maintained. The controller 1020 may generate a control signal to perform calibration of the camera module 1050 when the initially stored mounting position, direction, viewing angle information of the camera module 1050 and the measured mounting position, direction, viewing angle information of the camera module 1050 during the travel of the autonomous driving vehicle 900 change by more than a critical value.

[0198] In the present embodiment, the controller 1020 may include a memory 1022 and a processor 1024. The processor 1024 can execute the software stored in the memory 1022 according to the control signal of the controller 1020. Specifically, the controller 1020 stores the data and instructions for executing the lane detection method according to the present invention in the memory 1022, and the instructions can be executed by the processor 1024 to implement one or more methods disclosed herein.

[0199] Here, the memory 1022 can be stored in a non-volatile recording medium executable by the processor 1024. The memory 1022 can store software and data by appropriate internal and external devices. The memory 1022 can be composed of a RAM (random access memory), a ROM (read only memory), a hard disk, and a memory 1022 device connected to a dongle.

[0200] Memory 1022 can store at least an operating system (OS), user applications, and executable instructions. Memory 1022 can also store application data and array data structures.

[0201] Processor 1024 is a microprocessor or a suitable electronic processor and can be a controller, microcontroller, or state machine.

[0202] Processor 1024 can be implemented by a combination of computing devices, and the computing devices can be digital signal processors, microprocessors, or a suitable combination thereof.

[0203] On the other hand, the autonomous mobile 900 can further include a user interface 908 for user input to the above-described control device 1000. The user interface 908 can enable the user to input information through appropriate interaction. For example, it can be realized by a touch screen, keypad, operation buttons, etc. The user interface 908 transfers the input or command to the controller 1020, and the controller 1020 can perform the control operation of the mobile based on the response to the input or command.

[0204] Also, the user interface 908 is a device external to the autonomous mobile 900 and can communicate with the autonomous mobile 900 via the wireless communication device 1030. For example, the user interface 908 can be made interoperable with a mobile phone, tablet, or other computer device.

[0205] Furthermore, in this embodiment, the autonomous driving vehicle 900 has been described as including the engine 906, but it is also possible to include other types of propulsion systems. For example, the vehicle can be powered by electric energy, hydrogen energy, or a hybrid system combining these. Therefore, the controller 1020 includes the propulsion mechanism of the propulsion system of the autonomous driving vehicle 900, and can provide control signals according to this to the configuration of each propulsion mechanism.

[0206] Hereinafter, with reference to FIG. 19, the detailed configuration of the control device 1000 according to this embodiment will be described in more detail.

[0207] The control device 1000 includes a processor 1024. The processor 1024 may be a general-purpose single or multi-chip microprocessor, a dedicated microprocessor, a microcontroller, a programmable gate array, or the like. The processor may also be referred to as a central processing unit (CPU). Also, the processor 1024 can be used as a combination of a plurality of processors.

[0208] The control device 1000 also includes a memory 1022. The memory 1022 may be any electronic component capable of storing electronic information. In addition to a single memory, the memory 1022 can also include a combination of memories 1022.

[0209] The data and instruction words 1022a for performing the distance measurement method of the distance measurement device according to the present invention may be stored in the memory 1022. When the processor 1024 executes the instruction words 1022a, all or part of the instruction words 1022a and the data 1022b necessary for the execution of the instructions may be loaded onto the processor 1024 as instruction words 1024a and data 1024b.

[0210] The control device 1000 may also include a transmitter 1030a, a receiver 1030b, or a transceiver 1030c for allowing transmission and reception of signals. One or more antennas 1032a, 1032b may be electrically connected to the transmitter 1030a, the receiver 1030b, or each transceiver 1030c, and may further include an antenna.

[0211] The control device 1000 may include a digital signal processor (DSP) 1070. The DSP 1070 can enable the mobile body to quickly process digital signals.

[0212] The control device 1000 may also include a communication interface 1080. The communication interface 1080 may include one or more ports and / or communication modules for connecting other devices to the control device 1000. The communication interface 1080 can enable interaction between the user and the control device 1000.

[0213] The various components of the control device 1000 may all be connected by one or more buses 1090. The buses 1090 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 can transmit mutual information via the buses 1090 to perform the intended functions.

[0214] On the one hand, in various embodiments, the control device 1000 can be associated with a gateway for communication with a security cloud. For example, referring to FIG. 20, the control device 1000 can be associated with a gateway 1105 for providing information obtained from at least one of the components 1101 - 1104 of the vehicle 1100 to the security cloud 1106. For example, the gateway 1105 can be included within the control device 1000. As another example, the gateway 1105 may be configured as another device within the vehicle 1100 distinct from the control device 1000. The gateway 1105 communicably connects the networks within the vehicle 1100 secured by the software management cloud 1109, the security cloud 1106, and the in-vehicle security software 1110, which have different networks from each other.

[0215] For example, the component 1101 may be a sensor. For example, the sensor can be used to obtain information regarding at least one of the state of the vehicle 1100 or the state around the vehicle 1100. For example, the component 1101 can include a sensor 1410.

[0216] For example, the component 1102 may be an ECU (electronic control unit). For example, the ECU can be used for engine control, transmission control, airbag control, and tire pressure management.

[0217] For example, component 1103 may be an instrument cluster. For example, the instrument cluster may mean a panel located in front of the driver's seat on the dashboard. For example, the instrument cluster can be configured to show the driver (or passenger) information necessary for driving. For example, the instrument cluster can be used to display at least one of a visual element for indicating the number of revolutions per minute (RPM) of the engine, a visual element for indicating the speed of the vehicle 1100, a visual element for indicating the remaining fuel level, a visual element for indicating the gear state, or a visual element for indicating the information acquired by component 1101.

[0218] For example, component 1104 may be a telematics device. For example, the telematics device may mean a device that combines wireless communication technology and GPS (Global Positioning System) technology to provide various mobile communication services such as location information and safe driving within the vehicle 1100. For example, the telematics device can be used to connect the driver, the cloud (e.g., security cloud 1106), and / or the surrounding environment to the vehicle 1100. For example, the telematics device can be configured to support high bandwidth and low latency for 5G NR standard technology (e.g., 5G NR's V2X technology). For example, the telematics device can be configured to support the autonomous driving of the vehicle 1100.

[0219] For example, the gateway 1105 can be used to connect the network within the vehicle 1100 to the software management cloud 1109 and the security cloud 1106, which are networks outside the vehicle. For example, the software management cloud 1109 can be used to update or manage at least one software necessary for the running and management of the vehicle 1100. For example, the software management cloud 1109 can interact with the in-car security software 1110 installed in the vehicle. For example, the in-car security software 1110 can be used to provide security functions within the vehicle 1100. For example, the in-car security software 1110 can encrypt data transmitted and received via the in-vehicle network using an encryption key obtained from an external authorized server for the encryption of the in-vehicle network. In various embodiments, the encryption key used by the in-car security software 1110 can be generated corresponding to the identification information of the vehicle (vehicle number plate, vehicle VIN (vehicle identification number)) or information uniquely assigned to each user (for example, user identification information).

[0220] In various embodiments, the gateway 1105 can transmit data encrypted by the in-vehicle security software 1110 to the software management cloud 1109 and / or the security cloud 1106 based on the encryption key. The software management cloud 1109 and / or the security cloud 1106 can identify from which vehicle or user the data is received by decrypting the data encrypted by the encryption key of the in-vehicle security software 1110 using a decryption key. 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.

[0221] For example, the gateway 1105 can be configured to assist the in-vehicle security software 1110 and can be associated with the control device 1000. For example, the gateway 1105 can be associated with the control device 1000 to assist in connecting the control device 1000 with a client device 1107 connected to the security cloud 1106. As another example, the gateway 1105 can be associated with the control device 1000 to assist in connecting the control device 1000 with a third-party cloud 1108 connected to the security cloud 1106. However, it is not limited thereto.

[0222] In various embodiments, the gateway 1105 can be used to connect the vehicle 1100 with 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 of the operating software of the vehicle 1100 is required, and based on monitoring that an update of the operating software of the vehicle 1100 is required, can provide data for updating the operating software of the vehicle 1100 by the gateway 1105. As another example, the software management cloud 1109 can receive a request from a user requesting an update of the operating software of the vehicle 1100 from the vehicle 1100 via the gateway 1105, and based on the received request, can provide data for updating the operating software of the vehicle 1100. However, it is not limited thereto.

[0223] As described above, the present invention has been described mainly with reference to its preferred embodiments. All the embodiments and conditional examples disclosed herein are described for the purpose of assisting those of ordinary skill in the art in the technical field of the present invention to understand the principles and concepts of the present invention. Those skilled in the art can understand that the present invention can be implemented in a modified form without departing from the essential characteristics of the present invention.
