Description

Technical Field

[0001] The present invention relates to a method for recording a sudden acceleration of a vehicle using a pedal black box and an apparatus for performing such a method.

Background Art

[0002] Recently, in many automobile accidents, there have been accident videos and situations suspected of sudden acceleration, and the driver claims sudden acceleration of the automobile. However, there is no reliable method to prove whether a suspected sudden acceleration accident is an actual sudden acceleration. Therefore, only legal approaches regarding who is responsible for the cause investigation in society are being discussed.

[0003] Automobiles have black boxes that record accident situations in video. However, the black box does not record the situation of the driver's automobile operation. In addition, it is difficult to grasp the situation of the driver's automobile operation from other things such as the CCTV on the road at the time of the accident. Therefore, at the time of a suspected sudden acceleration accident, the stored video of the black box of another automobile at the accident scene may be used to check whether the driver was stepping on the brake or whether the taillight of the accident automobile was lit.

[0004] However, in fact, it is difficult to ensure a record that can confirm whether the automobile operated as intended by the driver.

[0005] Therefore, as a solution to the above-mentioned social safety problems, recently, pedal black boxes that photograph and record the brake pedal and the accelerator pedal have been gradually popularized.

[0006] Conventional pedal black boxes photographed all moments during driving and stored them in an internal storage device. However, the photographed video of the pedal black box is often not properly stored in the internal storage device for reasons such as not being stored due to an error in the internal storage device or the internal storage device being separated from the pedal black box due to the impact of an accident.

[0007] When the video taken by the pedal black box is not properly stored in the internal storage device, it is very difficult to prove the fact of sudden acceleration. If the driver cannot properly present evidence for a sudden acceleration accident of the vehicle, there is a problem that the driver cannot substantially receive damages for the sudden acceleration accident of the vehicle. Summary of the Invention Problems to be Solved by the Invention

[0008] One of the various problems of the present invention is that when a situation where sudden acceleration is suspected occurs, by storing all the video data in the storage unit and the external storage device, the disappearance of the video data can be prevented. Means for Solving the Problems

[0009] A method for recording sudden acceleration of a vehicle using a pedal black box including a camera unit, a communication unit, a control unit, a storage unit, and a sudden acceleration determination unit according to an exemplary embodiment of the present invention, comprising: obtaining video data of a periphery of a pedal unit of the vehicle by the camera unit; performing, by the control unit, a first mode of storing the video data in at least one of the storage unit or an external storage device provided independently of the pedal black box; determining, by the sudden acceleration determination unit, whether there is a sudden acceleration situation of the vehicle; and when it is determined in the determination step of whether there is a sudden acceleration situation of the vehicle that the vehicle is in a sudden acceleration situation, ending, by the control unit, the first mode and performing a second mode of storing all the video data in the storage unit and the external storage device.

[0010] The determination step of whether there is a sudden acceleration situation of the vehicle may include receiving vehicle information from the vehicle by the communication unit.

[0011] The vehicle information can include a first speed indicating the real-time driving speed of the vehicle, a second speed indicating the real-time GPS (Global Positioning System) speed of the vehicle, a first acceleration indicating the real-time acceleration of the vehicle, the foot position state of the driver, and the real-time acceleration duration of the vehicle.

[0012] The step of determining whether there is a sudden acceleration situation of the vehicle can further include a step of comparing the first acceleration received by the communication unit with a preset second acceleration to determine whether there is a sudden acceleration situation of the vehicle.

[0013] In the step of determining whether there is a sudden acceleration situation of the vehicle, when the first acceleration is greater than or equal to the second acceleration, the sudden acceleration determination unit can determine that the vehicle is in a sudden acceleration situation.

[0014] The step of determining whether there is a sudden acceleration situation of the vehicle can further include a step of comparing the value of the difference between the first speed and the second speed received by the communication unit with a preset value to determine whether there is a sudden acceleration situation of the vehicle.

[0015] In the step of determining whether there is a sudden acceleration situation of the vehicle, when the value of the difference between the first speed and the second speed is greater than or equal to the preset value, the sudden acceleration determination unit can determine that the vehicle is in a sudden acceleration situation.

[0016] The step of determining whether there is a sudden acceleration situation of the vehicle can further include a step of checking the foot position state information of the driver of the vehicle received by the communication unit and a step of comparing the real-time acceleration duration of the vehicle received by the communication unit with a preset first critical time to determine whether there is a sudden acceleration situation of the vehicle.

[0017] The foot position state of the driver of the vehicle can include a first state in which the driver's foot is separated from the brake by a predetermined interval and a second state in which the driver's foot is pressing the brake.

[0018] In the step of determining whether there is a sudden acceleration situation of the vehicle, when the foot position state of the driver of the vehicle is in the first state and the real-time acceleration duration of the vehicle is equal to or longer than the first critical time, the sudden acceleration determination unit can determine that the vehicle is in a sudden acceleration situation.

[0019] The step of checking the foot position state information of the driver of the vehicle and the step of determining whether there is a sudden acceleration situation of the vehicle can be performed in sequence.

[0020] The step of determining whether there is a sudden acceleration situation of the vehicle can further include a step of comparing the first speed received by the communication unit with a preset third speed.

[0021] In the step of comparing the first speed with the preset third speed, when the first speed is equal to or higher than the third speed, the sudden acceleration determination unit can determine whether there is sudden acceleration of the vehicle based on the duration of the first speed.

[0022] When the first speed is equal to or higher than the third speed and the duration of the first speed is equal to or longer than a preset second critical time, the sudden acceleration determination unit can determine that the vehicle is in a sudden acceleration situation.

[0023] The step of determining whether there is a sudden acceleration situation of the vehicle can further include a step of determining whether a preset command word is included in an audio signal generated based on the conversations of the driver and passengers input by the input unit.

[0024] In the step of determining whether the preset command word is included in the audio signal, when the command word is included in the audio signal, the sudden acceleration determination unit can compare the decibel value of the audio signal with a preset decibel value to determine whether there is sudden acceleration of the vehicle.

[0025] When the voice command is included in the voice signal and the decibel value of the voice signal is equal to or greater than the preset decibel value, the rapid acceleration determination unit can determine that the vehicle is in a rapid acceleration situation.

[0026] In a pedal black box for recording rapid acceleration of a vehicle according to an exemplary embodiment of the present invention, a camera unit that captures the periphery of the pedal unit of the vehicle to generate video data, a storage unit including a first storage unit that stores the video data generated by the camera unit, a communication unit that is communicably provided with an external device and receives vehicle information from the vehicle, a rapid acceleration determination unit that determines the presence or absence of a rapid acceleration situation of the vehicle based on the vehicle information received by the communication unit, and a control unit that selects and performs at least one of a first mode and a second mode based on a signal from the rapid acceleration determination unit, wherein in the second mode, the communication unit can store all of the video data in an external storage device provided independently of the storage unit and the pedal black box.

[0027] A program stored in a computer-readable recording medium including program code for executing a method for recording rapid acceleration of a vehicle according to an exemplary embodiment of the present invention can be provided.

[0028] A computer-readable recording medium including program code for executing a method for recording rapid acceleration of a vehicle according to an exemplary embodiment of the present invention can be provided.

[0034] Hereinafter, with reference to the drawings, specific embodiments of the present invention will be described. The following detailed description is provided to facilitate a comprehensive understanding of the methods, apparatuses, and / or systems described herein. However, this is merely illustrative and the present invention is not limited thereto.

[0035] In describing embodiments of the present invention, if it is determined that a specific description of known technologies related to the present invention may obscure the gist of the present invention, the detailed description thereof will be omitted. Also, the terms described below are terms defined in consideration of the functions in the present invention, and these may vary depending on the intentions or conventions of users, operators, etc. Therefore, the definitions should be made based on the content throughout this specification. The terms used in the detailed description are merely for describing embodiments of the present invention and should never be restrictive. Unless otherwise clearly stated, the singular form of the expression includes the meaning of the plural form. In this description, expressions such as "including" or "comprising" are for indicating a certain characteristic, number, step, operation, element, part thereof, or combination, and should not be construed as excluding the existence or possibility of one or more other characteristics, numbers, steps, operations, elements, part thereof, or combinations other than those described.

[0036] Also, when describing the components of embodiments of the present invention, terms such as first, second, A, B, (a), (b), etc. can be used. 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, with reference to the drawings, a method for recording a sudden acceleration of a vehicle using a pedal black box and an apparatus for performing such a method will be described in detail.

[0038] FIG. 1 is a diagram showing the configuration of a vehicle 2000 to which a pedal black box according to an exemplary embodiment of the present invention is mounted, and FIG. 2 is a diagram showing the configuration of a control device 2100 of the vehicle of FIG. 1.

[0039] Referring to FIGS. 1 and 2, in the vehicle 2000 according to an exemplary embodiment, a pedal black box 1 and a digital rearview mirror can be mounted, and the vehicle 2000 can include a control device 2100 for controlling the digital rearview mirror.

[0040] Here, the vehicle 2000 can be an autonomous vehicle. However, the present invention is not necessarily limited thereto, and the vehicle 2000 can include all means of transportation defined by Article 2 of the Road Traffic Act ( "Automobile" means a tool manufactured for the purpose of moving on land by a prime mover or a tool manufactured for the purpose of moving on land by towing with this. However, those defined by a presidential decree are excluded).

[0041] The control device 2100 can control a digital rearview mirror that displays various information according to the situation and can improve the driving convenience and safety of the driver.

[0042] In some embodiments, at least one component of the pedal black box 1 can be integrated with at least one component of the control device 2100.

[0043] The control device 2100 can include a controller 2120 including a memory 2122 and a processor 2124, a sensor 2110, a wireless communication device 2130, a LIDAR 2140, and a camera module 2150.

[0044] The controller 2120 can be configured by the vehicle manufacturer at the time of manufacture or further configured for performing the function of autonomous driving after manufacture. Or, the configuration for performing continuous additional functions can be included by upgrading the controller 2120 configured at the time of manufacture.

[0045] The controller 2120 can transmit control signals to the sensor 2110, engine 2006, user interface (UI) 2008, wireless communication device 2130, LIDAR 2140, camera module 2150, and pedal black box 1, which are included as other components within the vehicle. Although not shown in the figure, control signals can also be transmitted to an acceleration device, braking system, steering device, or navigation device related to the running of the vehicle.

[0046] The controller 2120 can control the engine 2006. For example, when the vehicle 2000 senses the speed limit of the road during driving, it can control the engine 2006 so that the driving speed does not exceed the speed limit, or within the range not exceeding the speed limit, it can control the engine 2006 to accelerate the driving speed of the vehicle 2000. Additionally, when the environmental sensing modules 2004a, 2004b, 2004c, 2004d sense the external environment of the vehicle and transmit it to the sensor 2110, the controller 2120 can receive information about the external environment, generate a signal to control the engine 2006 or the steering device (not shown), and control the running of the vehicle.

[0047] When there is another vehicle or an obstacle in front of the vehicle, the controller 2120 can control the engine 2006 or the braking system to decelerate the running vehicle, and in addition to the speed, it can also control the trajectory, running route, and steering angle. Alternatively, the controller 2120 can generate necessary control signals according to the recognition information of other external environments such as the driving lane and driving signal of the vehicle, and control the running of the vehicle.

[0048] In addition to generating its own control signals, the controller 2120 can also communicate with surrounding vehicles or a central server, and transfer commands for controlling peripheral devices based on the received information, thereby making it possible to control the running of the vehicle.

[0049] In addition, when the position of the camera module 2150 is changed or the viewing angle is changed, the controller 2120 may generate a control signal to control the calibration of the camera module 2150 in order to prevent the accurate recognition of the vehicle or the lane from being difficult. Therefore, the controller 2120 can continuously maintain the normal mounting position, direction, viewing angle, etc. of the camera module 2150 by generating a calibration control signal for the camera module 2150, even if the mounting position of the camera module 2150 is changed due to vibrations or impacts generated during the movement of the vehicle 2000. The controller 2120 can generate a control signal to perform calibration of the camera module 2150 when the initial mounting position, direction, viewing angle information of the camera module 2150 stored in advance and the initial mounting position, direction, viewing angle information of the camera module 2150 measured during the running of the vehicle 2000 change by more than a critical value.

[0050] The controller 2120 can include a memory 2122 and a processor 2124. The processor 2124 can execute the software stored in the memory 2122 according to the control signal of the controller 2120. Specifically, the controller 2120 stores the data and instructions for detecting the field-of-view video from the rear video of the vehicle 2000 in the memory 2122, and the instructions can be executed by the processor 2124 to implement one or more of the methods disclosed herein.

[0051] Here, the memory 2122 can be stored in a non-volatile recording medium executable by the processor 2124. The memory 2122 can store software and data by an appropriate internal or external device. The memory 2122 can be composed of a RAM (random access memory), a ROM (read only memory), a hard disk, and a memory 2122 device connected to a dongle.

[0052] Memory 2122 can store at least an operating system (OS), user applications, and executable instructions. Memory 2122 can also store application data and array data structures.

[0053] Processor 2124 is a microprocessor or a suitable electronic processor and can be a controller, microcontroller, or state machine.

[0054] Processor 2124 can be realized by a combination of computing devices, and the computing devices can be digital signal processors, microprocessors, or a suitable combination thereof.

[0055] In addition, the control device 2100 can monitor the internal and external characteristics of the vehicle 2000 with at least one or more sensors 2110 and sense the state.

[0056] Sensor 2110 can be composed of at least one or more sensing modules 2004, and the sensing module 2004 can be realized at a specific position of the vehicle 2000 according to the purpose of sensing. It can be located at the lower part, rear end, front end, upper end, or side end of the vehicle 2000, and can also be located on internal components or tires of the vehicle.

[0057] Thereby, the sensing module 2004 can sense information related to driving, such as the engine 2006, tires, steering angle, speed, and vehicle weight, as internal information of the vehicle. In addition, at least one or more sensing modules 2004 can be composed of an acceleration sensor 2110, gyroscope, image sensor 2110, RADAR, ultrasonic sensor, LIDAR sensor, etc., and can sense the movement information of the vehicle 2000.

[0058] The sensing module 2004 can receive, as external information, specific data regarding the external environmental state such as the state information of the road on which the vehicle 2000 is located, information on surrounding vehicles, weather, etc., and can also sense vehicle parameters based on this. The sensed information can be stored in the memory 2122 temporarily or long - term according to the purpose.

[0059] The sensor 2110 can integrate and collect the information of the sensing module 2004 for collecting the information generated inside and outside the vehicle 2000.

[0060] The control device 2100 can further include a wireless communication device 2130.

[0061] The wireless communication device 2130 is configured to realize wireless communication between vehicles 2000. For example, it enables the vehicle 2000 to communicate with the user's mobile phone, or other wireless communication devices 2130, other vehicles, a central device (traffic control device), a server, etc. The wireless communication device 2130 can transmit and receive wireless signals according to the 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.

[0062] In addition, the vehicle 2000 can also realize communication between vehicles through the wireless communication device 2130. That is, the wireless communication device 2130 can communicate with other vehicles on the road through vehicle-to-vehicle (V2V) communication. The vehicle 2000 can transmit and receive information such as driving warnings and traffic information through vehicle-to-vehicle communication, and can also request information from other vehicles or receive requests. For example, the wireless communication device 2130 can perform V2V communication using a dedicated short-range communication (DSRC) device or a Cellular-V2V (C-V2V) device. In addition to communication between vehicles, communication between the vehicle and different things (such as electronic devices carried by pedestrians) (V2X, Vehicle to Everything communication) can also be realized by the wireless communication device 2130.

[0063] Moreover, the control device 2100 can include a LIDAR device 2140. The LIDAR device 2140 can detect objects around the vehicle 2000 during operation using data sensed by the LIDAR sensor. The LIDAR device 2140 transfers the detected information to the controller 2120, and the controller 2120 can operate the vehicle 2000 according to the detected information. For example, when the detected information indicates that there is a vehicle ahead traveling at a low speed, the controller 2120 can instruct the engine 2006 to reduce the speed of the vehicle. Or, it can instruct the vehicle to reduce the entering speed according to the curvature of the curve the vehicle is entering.

[0064] The control device 2100 can further include a camera module 2150. The controller 2120 can extract object information from the external image captured by the camera module 2150 and enable the controller 2120 to process the relevant information.

[0065] In addition, the control device 2100 can further include an imaging device for recognizing the external environment. In addition to the LIDAR 2140, RADAR, GPS devices, an odometry device, and other computer vision devices can be used, and these devices can operate selectively or simultaneously as necessary to enable more precise sensing.

[0066] The vehicle 2000 can further include a user interface 2008 for user input to the control device 2100 described above. The user interface 2008 can enable the user to input information through appropriate interaction. For example, it can be realized by a touch screen, a keypad, operation buttons, etc. The user interface 2008 transfers the input or command to the controller 2120, and the controller 2120 can perform the control operation of the vehicle in response to the input or command.

[0067] In addition, the user interface 2008 can enable the vehicle 2000 to communicate with a device outside the vehicle 2000 via the wireless communication device 2130. For example, the user interface 2008 can be made interoperable with a mobile phone, a tablet, or other computing devices.

[0068] Furthermore, although the vehicle 2000 has been described as including the engine 2006, it is also possible to include other types of propulsion systems. For example, the vehicle can be operated by electric energy, or by hydrogen energy or a hybrid system combining these. Therefore, the controller 2120 includes the propulsion mechanism of the vehicle 2000 and can provide control signals according to this to the configuration of each propulsion mechanism.

[0069] Hereinafter, with reference to FIG. 2, the detailed configuration of the control device 2100 that controls the digital rearview mirror of the vehicle 2000 will be described in more detail.

[0070] The control device 2100 includes a processor 2124. The processor 2124 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). Further, the processor 2124 may be used as a combination of a plurality of processors.

[0071] The control device 2100 also includes a memory 2122. The memory 2122 may be any electronic component capable of storing electronic information. In addition to a single memory, the memory 2122 may also include a combination of memories 2122.

[0072] According to various embodiments, the data and instruction words 2122a for detecting the field-of-view video 220 from the rear video 210 of the vehicle 2000 may be stored in the memory 2122. When the processor 2124 executes the instruction words 2122a, all or part of the instruction words 2122a and the data 2122b required for the execution of the instructions may be loaded onto the processor 2124 as instruction words 2124a and data 2124b.

[0073] The control device 2100 may include a transmitter 2130a, a receiver 2130b, or a transceiver 2130c for allowing the transmission and reception of signals. One or more antennas 2132a, 2132b may be electrically connected to the transmitter 2130a, the receiver 2130b, or each transceiver 2130c, and may further include an antenna.

[0074] The control device 2100 may also include a digital signal processor (DSP) 2170. The DSP 2170 can enable the vehicle to quickly process digital signals.

[0075] The control device 2100 may also include a communication interface 2180. The communication interface 2180 may include one or more ports and / or communication modules for connecting other devices to the control device 2100. The communication interface 2180 can enable interaction between the user and the control device 2100.

[0076] The various components of the control device 2100 may all be connected by one or more buses 2190, and the buses 2190 may include a power bus, a control signal bus, a status signal bus, a data bus, etc. According to the control of the processor 2124, the components can transmit mutual information via the buses 2190 and perform the intended functions.

[0077] The pedal black box 1 can be fixed to the lower end of the driver's seat so as to photograph a pedal portion including a brake pedal and an accelerator pedal of the vehicle.

[0078] The external storage device 2 is provided independently of the pedal black box 1 and can receive video data from the pedal black box 1 via a communication unit 40 of the pedal black box 1 described later. The external storage device 2 can store the video data received from the pedal black box 1 in a predetermined storage space.

[0079] Hereinafter, with reference to FIG. 3, the detailed configuration of the pedal black box 1 will be described in more detail.

[0080] FIG. 3 is a diagram showing the configuration of a pedal black box for performing a method of recording a sudden acceleration of a vehicle according to an exemplary embodiment of the present invention.

As the communication unit 40 described later receives the ignition on signal or the ignition off signal of the vehicle 2000, the power supply unit 10 can turn on / off the power supply of the pedal black box 1.

[0083] When the ignition of the vehicle 2000 changes from the off state to the on state as the driver operates an ignition switch or a start button, etc., which turns the engine key, the vehicle 2000 can transfer the ignition on signal to the communication unit 40 of the pedal black box 1. The control unit 60 can sense that the ignition on signal has been received from the vehicle 2000 by the communication unit 40, and transfer a signal for controlling the pedal black box 1 to be turned on (on) to the power supply unit 10.

[0084] Also, when the driver finishes driving and the ignition of the vehicle 2000 changes from the on state to the off state as the driver operates the ignition switch or the start button, etc., the vehicle 2000 can transfer the ignition off signal to the communication unit 40 of the pedal black box 1. Here, the control unit 60 can sense that the ignition off signal has been received from the vehicle 2000 by the communication unit 40, and transfer a signal for controlling the pedal black box 1 to be turned off (off) to the power supply unit 10.

[0085] The camera unit 20 is composed of at least one or more cameras, and can photograph the periphery of the pedal unit including the brake pedal and the accelerator pedal of the vehicle 2000, and generate video data.

[0087] The camera unit 20 can be provided separately from the camera module 2150 of the control device 2100. That is, the camera unit 20 is installed at the lower end of the driver's seat to photograph the periphery of the pedal unit, while the camera module 2150 can be provided as a type of rearview mirror camera for photographing the inside or outside of the vehicle 2000.

[0089] In some embodiments, the camera unit 20 can include at least one or more infrared cameras to photograph the lower end of the driver's seat of the relatively dark vehicle 2000 and obtain high - quality video.

[0090] The camera unit 20 can have its mounting position, direction, and field of view controlled by a control signal that controls it to perform calibration of the control unit 60 described later.

[0091] The storage unit 30 stores the data necessary for the operation of the pedal black box 1 and the data generated by the operation of the pedal black box 1, and can be a data storage device incorporated inside the pedal black box 1.

[0092] The memory unit 30 can include a first memory unit 301 in which the video data generated by the camera unit 20 is stored, and a second memory unit 303 in which data necessary for the operation of various pedal black boxes 1 is stored.

[0093] The first memory unit 301 is incorporated in the pedal black box 1 and can store the video data of the pedal unit photographed and generated by the camera unit 20.

[0094] In some embodiments, at least one of eMMC (embedded MultiMediaCard), NAND, UFS (Universal Flash Storage), SSD (Solid State Drive), NOR flash memory, SD Card, CFast (CompactFlash Fast) Card, NVRAM (Non-Volatile Random Access Memory), and FRAM (Ferroelectric RAM) can be applied to the first memory unit 301.

[0095] The second memory unit 303 can store software and data by an appropriate internal or external device. The second memory unit 303 can be composed of a RAM (random access memory), a ROM (read only memory), a hard disk, and the like.

[0096] The communication unit 40 can be provided for communicating with the pedal black box 1 and other devices such as the vehicle 2000, the wireless communication device 2130 of the digital rearview mirror, and the external storage device 2, or the internal system of the pedal black box 1. The communication unit 40 can include a short-range communication module 401 and a wired communication module 403.

[0097] The short - range communication module 401 can wirelessly transmit and receive data over a short distance and support the interaction between the pedal black box 1 and other devices through various short - range wireless communications. The short - range communication module 401 can be any one of Wi - Fi, Bluetooth, Long - Term Evolution (LTE), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Global Systems for Mobile Communications (GSM), NFC (Near Field Communication), and Zigbee.

[0098] The short - range communication module 401 can preferably be Wi - Fi, but the present invention is not necessarily limited thereto.

[0099] In some embodiments, the pedal black box 1 can also communicate with other devices such as the external storage device 2 or the internal system of the pedal black box 1 via a short - range communication module located outside the pedal black box 1.

[0100] The pedal black box 1 can separately store and manage video data in the external storage device 2 via the short - range communication module 401.

[0101] The wired communication module 403 transmits and receives data via electrical signals or optical signals and can use a cable as a medium when transmitting data. More specifically, the wired communication module 403 can be a USB module that can communicate via a USB port.

[0102] In some embodiments, the pedal black box 1 of the present invention may communicate with other devices or the internal system of the pedal black box 1 using only one of the short-range communication module 401 and the wired communication module 403 as needed, or may communicate with other devices or the internal system of the pedal black box 1 using both the short-range communication module 401 and the wired communication module 403.

[0103] Based on at least one or more pieces of information of the vehicle 2000 received via the communication unit 40, the rapid acceleration determination unit 50 can determine whether there is a rapid acceleration situation of the vehicle 2000.

[0104] The rapid acceleration determination unit 50 can receive the information of the vehicle 2000 from the internal and external information of the vehicle 2000 sensed by the sensing module 2004 or the movement information of the vehicle 2000.

[0105] The information of the vehicle 2000 may include a first speed indicating the real-time driving speed of the vehicle 2000, a second speed indicating the real-time GPS (Global Positioning System) speed of the vehicle 2000, a first acceleration indicating the real-time acceleration of the vehicle 2000, the foot position state of the driver, and the real-time acceleration duration of the vehicle 2000.

[0106] In addition to the information of the vehicle 2000, the rapid acceleration determination unit 50 can also analyze an audio signal generated based on the speech of the driver and passengers input via the input unit 70 described below, and determine whether there is an occurrence of a rapid acceleration situation of the vehicle 2000.

[0107] Further, the rapid acceleration determination unit 50 can also determine whether there is a rapid acceleration situation according to whether a manual operation signal is input to the input unit 70. Needless to say, in other cases where a rapid acceleration suspicion situation occurs, it can be sensed and determine whether there is an occurrence of a rapid acceleration situation.

[0108] The control unit 60 can generate control signals for controlling various operations of the pedal black box 1. The control unit 60 can generate a control signal for selecting and performing at least one of the first mode or the second mode by determining the presence or absence of a sudden acceleration situation in the sudden acceleration determination unit 50.

[0109] The first mode can be a mode in which the video data captured via the camera unit 20 is stored in at least one of the storage unit 30 or an external storage device 2 provided independently of the pedal black box 1. More specifically, the first mode can be a mode in which the video data is stored in the first storage unit 301.

[0110] The second mode can be a mode in which the video data captured via the camera unit 20 is stored in both the storage unit 30 and the external storage device 2. That is, when the second mode is performed, the video data can be stored in its entirety in the first storage unit 301 and the external storage device 2.

[0111] According to an exemplary embodiment of the present invention, the pedal black box 1 can be controlled such that the video data is stored via either the first mode or the second mode according to the presence or absence of the occurrence of a sudden acceleration situation of the vehicle 2000 determined by the sudden acceleration determination unit 50 in the control unit 60.

[0112] When the sudden acceleration determination unit 50 determines that the vehicle 2000 is currently in a sudden acceleration situation, the control unit 60 can generate a control signal for performing the second mode. When the second mode execution signal is generated, since the video data captured by the camera unit 20 is stored in its entirety in the first storage unit 301 and the external storage device 2, it is possible to prevent the video data from being lost or damaged even if an error occurs in the first storage unit 301 or an impact of an accident due to sudden acceleration is applied.

[0113] On the one hand, the control unit 60 can generate a control signal that transmits data such as the presence or absence of a sudden acceleration of the vehicle 2000, the presence or absence of driving in the first mode or the second mode, the presence or absence of charging of the power battery of the pedal black box 1, and the on / off state of the pedal black box 1 to the driver via at least one of a display unit (not shown) of the vehicle 2000, the user interface 2008, or an audio signal.

[0114] Further, the control unit 60 may control the camera unit 20 so that the angle of the camera unit 20 and the like are adjusted according to the situation so that the video of the pedal unit is appropriately captured by the camera unit 20.

[0115] The control unit 60 generates a control signal for controlling the camera unit 20 to perform calibration. Even if the mounting position, direction, viewing angle, etc. of the camera unit 20 are changed due to vibrations or impacts generated during the running of the vehicle 2000, the camera unit 20 can be controlled to perform calibration according to the initially stored mounting position, direction, viewing angle information of the camera unit 20.

[0116] The input unit 70 can receive a driver input signal including an audio signal and a manual operation signal from the driver of the vehicle 2000.

[0117] The manual operation signal can be a signal formed when the driver manually operates an operation unit (not shown) formed on the pedal black box 1. The operation unit can be formed in the form of an emergency button, and when the driver presses the emergency button, the manual operation signal can be input to the input unit 70.

[0118] The audio signal can include the audio signals of the driver and other passengers riding in the vehicle 2000 in addition to the driver. The audio signal can be analyzed by the sudden acceleration determination unit 50, and the sudden acceleration determination unit 50 can determine the presence or absence of a sudden acceleration situation of the vehicle 2000 based on the audio signal.

[0119] The converter 80 is used to effectively process data and can convert parallel data into serial data or convert serial data into parallel data.

[0120] The converter 80 can receive data transmission from various sensors and systems of the pedal black box 1 such as the power supply unit 10, the camera unit 20, the memory unit 30, the communication unit 40, the sudden acceleration determination unit 50, the control unit 60, and the input unit 70, and convert and process this data.

[0121] In some embodiments, the converter 80 can be a deserializer. Therefore, the converter 80 can receive the serialized data collected from the various sensors and systems of the pedal black box 1, and can also convert this data into parallel data and process it.

[0122] The various sensors and systems in the pedal black box 1 record data in real time, and the data recorded in real time is serialized to improve transfer efficiency. The converter 80 can help the pedal black box 1 process multiple signals simultaneously by converting the serialized data into parallel data.

[0123] The external storage device 2 can be provided independently of the pedal black box 1.

[0124] In some embodiments, at least one of an SD (Secure Digital) card, a microSD card, a miniSD card, a CF (Compact Flash) card, a CFexpress card, an XQD card, a UFS (Universal Flash Storage) card, and a USB memory is applied to the external storage device 2, and it can be removably provided in the pedal black box 1.

[0125] However, the present invention is not necessarily limited thereto, and the external storage device 2 may exist in a storage space in another device or server. Therefore, the video data may be stored in the storage space of the external storage device 2 provided as any one of the driver's mobile phone, tablet PC, personal computer, and portable computer by the short-range communication module 401.

[0126] Hereinafter, with reference to FIGS. 4 to 6, a method for recording a sudden acceleration of the vehicle 2000 using the pedal black box 1 will be described in more detail.

[0127] FIG. 4 is a diagram showing a method for recording a sudden acceleration of a vehicle using a pedal black box according to an exemplary embodiment of the present invention, FIG. 5 is a diagram showing a step (S50) of determining the presence or absence of a sudden acceleration situation in FIG. 4, and FIG. 6 is a diagram showing a second mode execution step (S60) in FIG. 4.

[0128] First, the following will be described with reference to FIGS. 1 to 4 all together.

[0129] A method for recording a sudden acceleration of the vehicle 2000 using the pedal black box 1 according to an exemplary embodiment of the present invention may include a step (S10) of receiving an ignition-on signal of the vehicle 2000 by the communication unit 40, a step (S20) of turning on the power of the pedal black box 1 by the power supply unit 10, a step (S30) of obtaining peripheral shooting video data of the pedal part of the vehicle 2000 by the camera unit 20, a step (S40) of performing a first mode by the control unit 60, a step (S50) of determining the presence or absence of a sudden acceleration situation of the vehicle 2000 by the sudden acceleration determination unit 50, and a step (S60) of ending the first mode and performing a second mode.

[0130] The communication unit 40 can receive a signal due to a change in the ignition state from the vehicle 2000. When the ignition of the vehicle 2000 changes from the off state to the on state according to the driver's operation, the communication unit 40 can receive an ignition-on signal from the vehicle 2000 (S10).

[0131] When receiving the ignition-on signal of the vehicle 2000 from the communication unit 40 (S10), the control unit 60 can sense the ignition-on signal and transfer a signal for controlling the power supply of the pedal black box 1 to be in the on state to the power supply unit 10.

[0132] The power supply unit 10 can control the power supply of the pedal black box 1 from the off state to the on state according to the control signal of the control unit 60 (S20).

[0133] After the step (S20), the camera unit 20 can take a picture of the periphery of the pedal unit including the brake pedal and the accelerator pedal of the vehicle 2000 and obtain moving image data (S30).

[0134] The control unit 60 can perform a first mode in which the moving image data captured by the camera unit 20 is stored in at least one of the storage unit 30 or the external storage device 2 provided independently of the pedal black box 1 (S40).

[0135] In some embodiments, the first mode can be a mode in which the moving image data captured by the camera unit 20 is stored in the first storage unit 301.

[0136] After the step (S40), the rapid acceleration determination unit 50 can determine whether there is a rapid acceleration situation of the vehicle 2000 (S50).

[0137] When the rapid acceleration determination unit 50 determines that the vehicle 2000 is currently in a rapid acceleration situation (S50: Yes), the control unit 60 can end the first mode and perform a second mode (S60).

[0138] In one embodiment, the second mode can be a mode in which all of the video data captured by the camera unit 20 is stored in the first storage unit 301 and the external storage device 2.

[0139] On the other hand, when the rapid acceleration determination unit 50 determines that the vehicle 2000 is not in a rapid acceleration situation at present (S50: No), the control unit 60 can continue to control so that the video data is stored in the first mode (S40).

[0140] The pedal black box 1 can determine the presence or absence of a rapid acceleration situation at preset time intervals in step (S40) (S50).

[0141] When the rapid acceleration determination unit 50 of the pedal black box 1 according to an exemplary embodiment of the present invention determines that the vehicle 2000 is currently in a rapid acceleration situation (S50: Yes), the first mode is terminated, and the second mode in which all of the video data captured by the camera unit 20 is stored in the storage unit 30 and the external storage device 2 is performed (S60), thereby preventing the video data of the pedal black box 1 from disappearing.

[0142] Before step (S60), a step (not shown) of activating the short-range communication module 401 by the control unit 60 can be performed. When the rapid acceleration determination unit 50 determines that the vehicle 2000 is currently in a rapid acceleration situation (S50: Yes), the second mode can be performed by generating a control signal for activating the short-range communication module 401 by the control unit 60.

[0143] Hereinafter, with reference to all of FIGS. 1 to 5, the rapid acceleration situation determination step (S50) will be described in more detail.

[0144] The rapid acceleration determination unit 50 can receive vehicle 2000 information including internal and external information and driving information of the vehicle 2000 sensed by the sensing module 2004 of the vehicle 2000 through the communication unit 40 (S510).

[0145] The vehicle information can include a first speed indicating the real-time driving speed of the vehicle 2000, a second speed indicating the real-time GPS (Global Positioning System) speed of the vehicle 2000, a first acceleration indicating the real-time acceleration of the vehicle 2000, the foot position state of the driver, and the real-time acceleration duration of the vehicle 2000, etc.

[0146] The rapid acceleration determination unit 50 can compare the vehicle information received by the communication unit 40 to determine whether a rapid acceleration situation of the vehicle 2000 has occurred.

[0147] After the step (S510), the rapid acceleration determination unit 50 can compare the first acceleration with a preset second acceleration to determine whether there is a rapid acceleration situation of the vehicle 2000 (S520).

[0148] Here, the second acceleration may mean the maximum acceleration of the vehicle 2000. The second acceleration can be set as the maximum acceleration by converting the time it takes for the vehicle 2000 to accelerate to 100 km / h when accelerating maximally from a stopped state. Different values may be set for different vehicle types and stored in the second storage unit 303, or the same value may be set regardless of the vehicle type.

[0149] That is, the rapid acceleration determination unit 50 can compare the first acceleration received by the communication unit 40 with the second acceleration preset and stored in the second storage unit 303 to determine whether there is a rapid acceleration situation (S520).

[0150] For example, when the first acceleration is greater than or equal to the second acceleration (S520: Yes), the rapid acceleration determination unit 50 can determine that the vehicle 2000 is in a rapid acceleration situation. When the rapid acceleration determination unit 50 determines that the vehicle 2000 is in a rapid acceleration situation, the control unit 60 can end the first mode and generate a signal for controlling to perform the second mode (S40).

[0151] On the other hand, when the first acceleration is less than the second acceleration (S520: No), the rapid acceleration determination unit 50 compares the value of the difference between the first speed indicating the real-time traveling speed of the vehicle 2000 and the second speed indicating the real-time GPS (Global Positioning System) speed of the vehicle 2000 with a preset value, and can determine whether or not a rapid acceleration situation of the vehicle 2000 has occurred (S530).

[0152] In the case of the GPS (Global Positioning System) speed, signals are transmitted and received via satellites, and based on this, the position of the vehicle 2000 is calculated. Therefore, in the case of the GPS speed, since it takes several seconds to accurately measure the position, in the case of sudden acceleration or sudden deceleration, the reaction speed is delayed, and a difference may occur from the actual speed of the vehicle 2000.

[0153] The rapid acceleration determination unit 50 can receive the first speed and the second speed by the communication unit 40, obtain the value of the difference, compare the value of the difference with the preset value, and determine whether or not there is a rapid acceleration situation.

[0154] The value of the difference can be an absolute value that indicates the distance from the origin by a vertical line, regardless of whether it is a negative number or a positive number.

[0155] The preset value is a value set in advance and stored in the second storage unit 303, and may mean the allowable error of the value of the difference between the first speed and the second speed.

[0156] In some embodiments, the preset value can be 0.1 to 10 km / h.

[0157] In the step (S530), when the value of the difference between the first speed and the second speed is equal to or greater than the preset value (S530: Yes), the rapid acceleration determination unit 50 can determine that the vehicle 2000 is currently in a rapid acceleration situation. When the rapid acceleration determination unit 50 determines that the vehicle 2000 is in a rapid acceleration situation, the control unit 60 can generate a signal to end the first mode and control to perform the second mode (S40).

[0158] On the other hand, when the value of the difference between the first speed and the second speed is less than the preset value (S530: No), the rapid acceleration determination unit 50 can check the driver's foot position state information of the vehicle 2000 received by the communication unit 40 (S540).

[0159] The driver's foot position state can include a first state in which the driver's foot is separated from the brake pedal by a predetermined distance and a second state in which the driver's foot is positioned while pressing the brake pedal. The first state can include a state in which the driver is positioned while pressing the accelerator pedal.

[0160] In the step (S540), when the driver's foot position state of the vehicle 2000 is the first state (S540: Yes), the rapid acceleration determination unit 50 can compare the real-time acceleration duration of the vehicle 2000 received by the communication unit 40 with a preset first critical time to determine whether there is a rapid acceleration situation of the vehicle 2000 (S545).

[0161] The first critical time is a preset value stored in the second storage unit 303, and can mean the time that serves as a criterion for determining a rapid acceleration situation when the acceleration continues for a predetermined time or more even if the driver is not stepping on the accelerator pedal.

[0162] In some embodiments, the first critical time can be set to 0.5 to 10 minutes.

[0163] In the step (S545), when the real-time acceleration duration of the vehicle 2000 is equal to or greater than the first critical time (S545: Yes), the rapid start determination unit 50 can determine that the vehicle 2000 is in a rapid start situation. When the rapid start determination unit 50 determines that the vehicle 2000 is in a rapid start situation, the control unit 60 can generate a signal to end the first mode and control to perform the second mode (S40).

[0164] The above-described step of checking the driver's foot position state information (S540) and the step of comparing the real-time acceleration duration of the vehicle 2000 with the preset first critical time (S545) can be performed in order.

[0165] However, the present invention is not necessarily limited thereto, and the steps (S540, S545) may be performed simultaneously, and it goes without saying that the step of comparing the real-time acceleration duration of the vehicle 2000 with the preset first critical time (S545) and the step of checking the driver's foot position state information (S540) may be performed in this order.

[0166] On the other hand, in the step of checking the driver's foot position state information (S540), when the driver's foot position state of the vehicle 2000 is in the second state (S540: No) or in the step of comparing the real-time acceleration duration of the vehicle 2000 with the preset first critical time (S545), when the real-time acceleration duration of the vehicle 2000 is less than the first critical time, the rapid start determination unit 50 can compare the first speed received by the communication unit 40 with a preset third speed (S550).

[0167] The third speed is a preset value stored in the second storage unit 303, and when the vehicle 2000 travels at a speed equal to or higher than the third speed for a predetermined time or more, it can be a reference speed for determining that the vehicle 2000 is in a rapid start situation.

[0168] In some embodiments, the third speed can be a value of 110 km / h or more, which is the maximum speed standard for highways in South Korea.

[0169] For example, when the first speed is greater than or equal to the third speed (S550: Yes), the rapid acceleration determination unit 50 can determine the presence or absence of rapid acceleration of the vehicle 2000 based on the duration of the first speed (S555).

[0170] That is, when the first speed is greater than or equal to the third speed and continues for a second critical time or more (S555: Yes), the rapid acceleration determination unit 50 can determine that the vehicle 2000 is in a rapid acceleration situation. When the rapid acceleration determination unit 50 determines that the vehicle 2000 is in a rapid acceleration situation, the control unit 60 can generate a signal to end the first mode and control to perform the second mode (S40).

[0171] The second critical time is a preset value stored in the second storage unit 303, and can be a critical time serving as a reference for determining the presence or absence of a rapid acceleration situation of the vehicle 2000 when the vehicle 2000 travels at a speed greater than or equal to the reference speed (third speed) for a predetermined time or more.

[0172] In some embodiments, the second critical time can be set to 0.5 to 10 minutes.

[0173] The above-described step of comparing the first speed with the preset third speed (S550) and the step of determining whether the first speed is greater than or equal to the third speed and continues for a second critical time or more (S555) can be performed in the above order sequentially.

[0174] In some embodiments, after the step of comparing the first speed with the preset third speed (S550), the control unit 60 can further include a step of generating an overspeed notification signal to the driver (not shown).

[0175] That is, when the rapid acceleration determination unit 50 determines that the first speed is equal to or higher than the third speed (S550: Yes), the control unit 60 can generate an overspeed notification signal. The control unit 60 can generate an overspeed notification signal that is transmitted to the driver by at least one of the display unit (not shown) of the vehicle 2000, the user interface 2008, or an audio signal.

[0176] After the overspeed notification signal is transferred, when the vehicle 2000 maintains a speed equal to or higher than the third speed for a duration equal to or longer than the second critical time (S555: Yes), the rapid acceleration determination unit 50 can determine that the vehicle 2000 is in a rapid acceleration situation. When the rapid acceleration determination unit 50 determines that the vehicle 2000 is in a rapid acceleration situation, the control unit 60 can generate a signal for ending the first mode and controlling to perform the second mode (S40).

[0177] On the other hand, when the first speed is lower than the third speed (S550: No) or when the first speed is equal to or higher than the third speed and lasts for a duration shorter than the second critical time (S555: No), the rapid acceleration determination unit 50 can determine the presence or absence of a rapid acceleration situation based on the audio signal input by the input unit 70 (S560, S565).

[0178] The audio signal can be generated based on the conversations of the driver and all passengers inside the vehicle 2000. The input unit 70 can convert the conversations of the driver and all passengers into data and transfer it to the rapid acceleration determination unit 50, the control unit 60, etc.

[0179] First, the rapid acceleration determination unit 50 can determine whether the audio signal contains a preset command word (S560). The command word can be preset as a word that can infer a rapid acceleration situation, starting with "rapid acceleration", and can be stored in the second storage unit 303.

[0180] In the step (S560), when it is determined that at least one of the words set as the command word in the voice signal is included (S560: Yes), the rapid acceleration determination unit 50 can measure the decibel value of the voice signal and compare it with a preset decibel value to determine whether there is rapid acceleration of the vehicle (S565).

[0181] The preset decibel value is a value preset and stored in the second storage unit 303, and can be a reference value for determining that a rapid acceleration situation has occurred when the decibel value of the voice signal is greater than the preset decibel value.

[0182] In the step (S565), when the decibel value of the voice signal is equal to or greater than the preset decibel value (S565: Yes), the rapid acceleration determination unit 50 can determine that the vehicle 2000 is currently in a rapid acceleration situation. When the rapid acceleration determination unit 50 determines that the vehicle 2000 is in a rapid acceleration situation, the control unit 60 can end the first mode and control to perform the second mode (S40).

[0183] That is, the rapid acceleration determination unit 50 can analyze the voice signal and determine whether the vehicle 2000 is in a rapid acceleration situation based on whether the command word is included (S560) and the decibel value of the voice signal as a reference (S565).

[0184] On the other hand, when the preset command word is not included in the voice signal (S560: No) or the decibel value of the voice signal is less than the preset decibel value (S565: No), the rapid acceleration determination unit 50 can determine whether there is a rapid acceleration situation according to whether a manual operation signal is input from the input unit 70 (S570).

[0185] The pedal black box 1 can include an emergency button (not shown). The emergency button may be integrally formed on the pedal black box 1, or may be independently formed at positions such as the dashboard or the rearview mirror of the vehicle 2000.

[0186] The manual operation signal can be a signal input by manual operation of the driver or the passenger. When the emergency button is pushed by the driver or the passenger, the control unit 60 can sense the operation of the emergency button and transfer the manual operation signal to the rapid start determination unit 50.

[0187] That is, when the rapid start determination unit 50 receives the manual operation signal from the control unit 60 (S570: Yes), it can determine that the vehicle 2000 is in a rapid start situation. When the rapid start determination unit 50 determines that the vehicle 2000 is in a rapid start situation, the control unit 60 can end the first mode and perform the second mode (S60).

[0188] In the present embodiment, the steps (S520, S530, S540, S550, S560, S570) for determining the presence or absence of the above-described rapid start situation are illustrated as being performed in order, but the present invention is not necessarily limited thereto, and it goes without saying that the steps (S520, S530, S540, S550, S560, S570) may be performed simultaneously.

[0189] Hereinafter, with reference to FIGS. 1 to 4 and FIG. 6, the step (S60) of ending the first mode and performing the second mode will be described in more detail.

[0190] When it is determined by the step (S50) of determining the presence or absence of a rapid start situation that the vehicle 2000 is in a rapid start situation, the control unit 60 can generate a control signal for ending the first mode (S610).

[0191] When the first mode ends (S610), the control unit 60 can generate a notification for notifying the driver of the execution of the second mode. The second mode execution notification can be transferred to the driver via a guidance voice or a display unit (not shown).

[0192] When the first mode ends, the control unit 60 can generate a control signal for performing the second mode (S630). By performing the step (S630), all of the video of the pedal unit captured by the camera unit 20 can be stored in the first storage unit 301 and the external storage device 2.

[0193] The second mode execution notification generation step (S620) and the second mode execution step (S630) may be performed simultaneously.

[0194] When the second mode is performed (S630), the rapid acceleration determination unit 50 can perform a step (S640) of determining whether the rapid acceleration situation continues at preset time intervals.

[0195] Since the step (S640) is performed in substantially the same process as the step (S50) for determining the presence or absence of a rapid acceleration situation described with reference to FIG. 5, a detailed description thereof will be omitted.
