In addition, the controller 360 analyzes the image data stored in the data storage unit 330 to perform a lane departure warning, a preceding vehicle collision warning, a safety state warning when changing lanes, a pedestrian collision warning, a danger zone warning, and the like. It may be possible to perform a function that helps safe operation of the vehicle.

In addition, when the driving information is not transmitted from the connected vehicle mounting apparatus 200, the vehicle image storage device 300 may further include a driving information generator 380.

The driving information generation unit 380 may include vehicle information and / or sensing information transmitted from the vehicle mounting apparatus 200 through the first interface unit 340, and the vehicle information collection unit provided in the vehicle image storage device 300.

Here, the vehicle information collecting unit and / or the sensing unit are the same as the vehicle information collecting unit 210 and / or the sensing unit 220 illustrated in FIG. 3, and thus the detailed description thereof will be omitted.

However, the sensing unit may include an inertial sensor unit, and may determine whether an event such as a vehicle accident occurs using the sensing value of the inertial sensor unit. For example, the sensing value may be determined as an event for a preset threshold value, or may be determined as an event when the trend of the sensing value for a predetermined time is checked and the amount of change exceeds a predetermined amount. When it is determined that the event has occurred as described above, the video signal input through the image input unit 310 is stored as an event image in the data storage unit 330, and the event image determines the time and / or cost of the dispute in case of a dispute due to a vehicle accident later. It can be used as video material for.

The vehicle image storage device 300 may further include one or more of a signal generator, an output unit, a power supply unit, an auxiliary power supply unit, a program storage unit, a wired / wireless communication unit, and the like.

The signal generator generates and outputs a predetermined attachment signal.

The timer unit provides real time information to the vehicle image storage device 300. Since the time information needs to be maintained even when the power is cut off, an auxiliary power supply or a dedicated backup battery can be used.

As described with reference to FIGS. 3 and 4, collection of vehicle information, sensing of sensing information, and generation of driving information may be performed by the vehicle mounting apparatus 200 and / or the vehicle image storage device 300.

On the contrary, for the convenience of understanding and explanation of the present invention, the vehicle mounting apparatus 200 performs vehicle information collection, sensing information sensing, and generation of driving information, collected vehicle information, sensed sensing information, and generated information. It will be described on the assumption that the driving information is transmitted to the vehicle image storage device 300.

5 is a flowchart illustrating a process of generating driving information in a vehicle mounting apparatus according to an embodiment of the present invention.

Referring to FIG. 5, in step S310, the vehicle mounting apparatus 200 determines whether power supply from a vehicle is detected. The vehicle mounting apparatus 200 is configured to directly supply power from a battery of the vehicle by starting on the vehicle, or a power input terminal is coupled to a vehicle power supply terminal (for example, a cigar jack) so that the vehicle It may be configured to receive power from. In addition, as will be described later, the vehicle mounting apparatus 200 may further include an auxiliary power supply to enable generation of driving information even when power is not supplied from the vehicle.

The detection of the power supply is determined from the change in the power voltage applied to the vehicle mounting apparatus 200 from the battery of the vehicle, confirms the on / off of the ACC power of the vehicle, or directly receives the start signal of the vehicle. Can be performed.

For example, when it is determined from the change in the power supply voltage applied from the battery of the vehicle, the control unit 260 may apply after confirming the start-off voltage and the start-on voltage of the initial predetermined number or more. Alternatively, the battery voltage of a general vehicle is about 12V, and when the start is made, the voltage is increased to about 13.5V. If there is a voltage change of about 12V to 13.5V, the starter may be determined to have started. Here, in the case where the engine is turned off immediately after starting by the hysteresis method, it can be determined that the starting is not started.

If it is detected that power is supplied from the vehicle, in step S320, the vehicle mounting apparatus 200 generates and stores driving information in a predetermined manner after the operation is started.

The driving information is information on whether the vehicle is used in the form of driving or the like, and may be used as data for providing benefits or disadvantages to the driver as described above. For example, when driving information is provided to a control center and shared among insurance companies, it can be used as data for calculating premium differentials.

When the vehicle mounting apparatus 200 detects that power is supplied, the vehicle mounting apparatus 200 may perform a self-diagnosis whether a component in a standby state operates normally before generating driving information. For example, the timer unit transmits a predetermined command to the vehicle information collecting unit 210, the sensing unit 220, the detachable detecting unit 230, and the like, whether time is normally flowing through communication, and whether a normal response is received. Self-diagnosis is possible by checking. If there is an abnormal component, an error message, an error voice or an alarm may be output through the output unit, and a corresponding history may be recorded in the data storage unit 250.

In operation S331, the vehicle mounting apparatus 200 detects whether the vehicle image storage device 300 is attached or detached.

Detachment detection of the vehicle image storage device 300 may be performed by the detachment detecting unit 230 as described above. For example, the level of a specific signal shared by the vehicle image storage device 300 and the vehicle mounting device 200 or the vehicle mounting device 200 and the vehicle image storage device 300 are connected through the connection housing 400. When performing communication through the housing 400, whether or not the vehicle image storage device 300 responds to a request of the vehicle mounting apparatus 200 may be detected by using the presence or absence of a response. Alternatively, when the vehicle image storage device 300 includes a signal generator that generates an attachment signal, the vehicle image storage device 300 may detect whether the vehicle image storage device 300 is attached or detached according to whether the corresponding signal is received through the connection housing 400. There will be.

When the vehicle image storage device 300 is normally mounted, power is supplied to the vehicle image storage device 300. In operation S332, vehicle information and / or sensing information output from the vehicle information collecting unit 210 and / or the sensing unit 220 may be acquired. In addition, the driving information generation unit 270 may generate driving information by using the acquired vehicle information and / or sensing information, including the detachable information.

The generation of the driving information may be performed by the driving information generating unit 270. For this purpose, acquisition information provided from the vehicle information collecting unit 210 and / or the sensing unit 220 (ie, vehicle information and / or sensing). Information) and removable information can be used.

The driving information may include, for example, one or more of a driving date, a driving distance, a driving speed, a turn signal signal when turning left and right, a seat belt worn, an accelerator pedal signal, a brake signal, a fuel level signal, a fuel injection amount signal, and the like. have. In addition, the driving information may include verification information to be described later.

The information (one or more of vehicle information, sensing information, and driving information generated using the same) already stored in the data storage unit 250 in step S333 and the acquisition information and / or the generated driving information acquired in step S332 are used for the vehicle. The image storage device 300 is transmitted.

When the vehicle image storage device 300 is not normally mounted, the driver or user is visually and acoustically informed of the detached state of the vehicle image storage device 300 through an output unit in step S334.

In operation S335, information related to driving of the vehicle (for example, one or more of vehicle information, sensing information, and driving information generated using the same) is stored in the data storage unit 250 together with the time information at a predetermined time. .

In operation S340, the vehicle mounting apparatus 200 determines whether the power supply is cut off. The vehicle mounting apparatus 200 is cut off from the vehicle when the vehicle is turned off and / or the power input terminal is disconnected from the vehicle power supply terminal. In this case, the vehicle mounting apparatus 200 may be driven by receiving driving power from the charged power of the auxiliary power unit. Hereinafter, when the power supply from the vehicle is cut off due to the start-off of the vehicle, the driving apparatus of the vehicle 200 is driven. The case where this ends is demonstrated.

If the power supply is maintained from the vehicle, the flow proceeds to step S331 again. However, if the power supply from the vehicle is stopped, the process proceeds to step S310 again.

If it is determined in step S310 that power is not supplied from the vehicle or the vehicle mounting apparatus 200 remains turned off (end of operation), the process proceeds to step S350 and whether the vehicle mounting apparatus 200 is a preset time. Judge. Here, the preset time may be designated at a predetermined time period or may be set at an arbitrary time.

This may be due to the lack of use of the vehicle and thus the lack of power supply (or turn on, which is the same below), or the disadvantage that would be incurred by the creation and storage of accurate driving information, for example, even when the vehicle is in use. Prevention, etc.) to determine whether power is not supplied to the vehicle mounting apparatus 200.

If it is not the set time, the flow advances to step S310 again. However, when the set time is reached, the vehicle mounting apparatus 200 proceeds to step S360 and after operation starts, generates and stores driving information in a predetermined manner in step S370.

At this time, unlike the above-described process of step S331, since the vehicle mounting apparatus 200 is driven by the power supplied by the auxiliary power supply, it can be operated to minimize power consumption. For example, power consumption may be minimized by recognizing and storing only minimal information (for example, driving distance or GPS location coordinates) for recognizing driving status or a change in location of the vehicle.

In step S380, the vehicle mounting apparatus 200 ends the operation and then proceeds to step S310 again.

It is apparent that the above-described driving information providing method may be performed by an automated procedure in a time series order by a software program embedded in a vehicle mounting apparatus. The codes and code segments that make up the program can be easily deduced by a computer programmer in the field. In addition, the program is stored in a computer readable media, and read and executed by a computer to implement the method. The information storage medium includes a magnetic recording medium, an optical recording medium, and a carrier wave medium.

Here, the vehicle mounting apparatus 200 verifies whether there has been a use of the vehicle by using the driving information generated through steps S332, S335, or S370 or information obtained for generating the corresponding driving information. The verification data and / or the verification result may be stored in the data storage 250.

Through this verification, it is possible to confirm whether driving information about the use of the vehicle (eg, driving) or not (eg, parking) is being generated normally.

Hereinafter, some embodiments in which the vehicle mounting apparatus 200 verifies whether the normal generation of the driving information is maintained or whether the driver does not cause an inoperable state due to an illegal purpose are briefly described. However, in addition to the exemplary embodiments described below, the verification method for the same purpose may vary. It is also obvious that embodiments for verification may be used in combination of more than one.

6 is a flowchart illustrating a method for verifying driving information in a vehicle mounting apparatus according to an embodiment of the present invention.

In operation S410, the detachable attachment of the vehicle image storage device 300 that is detachable from the vehicle mounting apparatus 200 is detected. The method for detecting detachment may be one of steps S410a, S410b, or S410c.

First, in step S410a, the level of a signal shared by the vehicle mounting apparatus 200 and the vehicle image storage device 300 is measured. If the vehicle image storage device 300 is attached to the vehicle mounting apparatus 200, the level of the shared signal will be relatively large. Therefore, if the level of the measured signal is greater than or equal to the specified reference value, it is attached. You can judge by the state.

Alternatively, in operation S410b, the vehicle mounting apparatus 200 transmits a predetermined request to the vehicle image storage device 300. At this time, the request is preferably wired. If a normal response is received from the vehicle image storage device 300 with respect to the transmitted request, it may be determined to be in an attached state, and in the case of not receiving a normal response or receiving no response, it may be determined as a detached state.

Alternatively, in step S410c, the connection housing 400 to be described later may be used. The detachable state of the vehicle image storage device 300 may be detected by detecting whether the first contact terminal and the second contact terminal provided in the connection housing 400 are in contact with each other. The contact signal changes as soon as it is attached or detached and can be detected by measuring it.

In operation S420, according to the detection result in operation S410, the vehicle image storage device 300 stores time information regarding the detached first view point and the attached second view point in the data storage unit 250.

The first vehicle information and the first sensing information corresponding to the time information of the first time point and the second time point stored in operation S430 are extracted and compared with the second vehicle information and the second sensing information. Then, it is determined whether the driving information is normally generated based on the comparison result.

For example, the driving information generated while the vehicle image storage device 300 is detached is determined to be abnormally generated, and a penalty such as an insurance premium increase due to the unattached operation of the vehicle image storage device 300 is applied, and an accident within the period of time. Disadvantages, such as non-payment of insurance benefits, may be provided.

Here, the first sensing information and the second sensing information include one or more of location information and environment information. The location information includes a GPS location sensed by the location information unit, and the environment information includes one or more of temperature, humidity, brightness, etc. detected by the environment sensor unit.

In this case, the sensing unit 220 may store the sensing information generated by performing a sensing operation at a predetermined cycle in the data storage unit 250. In this case, the first sensing information corresponding to the first time information may include sensing information stored at a time point according to the first time information, that is, a time point closest to the detachment time point (ie, sensing information generated by the sensing unit 220 before detachment or detachment). Immediately after the sensing unit 220 generates the sensing information corresponding to the second time information, the sensing information stored at the time point according to the second time information, that is, the time closest to the attachment time (that is, before attachment). Sensing information generated by the sensing unit 220 or sensing information generated by the sensing unit 220 immediately after attachment.

However, in some cases, the sensing unit 220 may generate sensing information by performing a sensing operation in real time. In this case, the sensing unit 220 detects the detachment or attachment of the vehicle image storage device 300 and performs the sensing operation. The sensing information may be stored in the data storage 250.

7 is a flowchart illustrating a method for verifying driving information in a vehicle mounting apparatus according to another embodiment of the present invention.

In step S460, it is detected whether the vehicle mounting apparatus 200 itself is normally installed in the vehicle. The method of detecting the detachment of the vehicle mounting apparatus 200 may be one of steps S460a, S460b, or S460c.

First, in step S460a, the detachable detecting unit 230 may include an environmental sensor unit to detect whether the vehicle mounting apparatus 200 is located inside the vehicle. To this end, a sensing value including one or more environmental information among temperature, humidity, and brightness is acquired at predetermined time intervals, and the acquired sensing value is an average of an expected sensing value of the vehicle interior or past sensing values, that is, an average sensing value. Through comparison, it is possible to determine whether the vehicle mounting apparatus 200 is detachable.

If the currently measured sensing value is out of a predetermined threshold (for example, within 80 to 120% of the sensing expectation value or the sensing average value) with respect to the sensing expectation value or the sensing average value, the vehicle mounting apparatus 200 may be detached from the vehicle. You will be able to detect it.

Alternatively, in step S460b, when the vehicle mounting apparatus 200 is installed in the vehicle, the detachable state of the vehicle mounting apparatus 200 may be detected by detecting contact control information using the contact type switch provided in the installation portion.

Alternatively, in step S460c, when the vehicle mounting apparatus 200 is set to periodically communicate with a predetermined communication module installed in the vehicle, the vehicle mounting apparatus according to whether or not communication with the corresponding communication module is performed at regular intervals is performed properly. Detachable state of the 200 can be detected. For example, if communication is not performed properly, it may be determined that the vehicle mounting apparatus 200 is placed in a detached state from the vehicle.

In operation S470, according to the detection result in operation S460, time information regarding the first time point where the vehicle mounting apparatus 200 is detached and the second time point that is attached is stored in the data storage unit 250.

The first vehicle information and the first sensing information corresponding to the time information of the first time point and the second time point stored in step S480 are extracted and compared with the second vehicle information and the second sensing information. Then, it is determined whether the driving information is normally generated based on the comparison result.

For example, it is determined that the driving information generated while the vehicle mounting apparatus 200 is detached, that is, not normally installed, is abnormally generated, and a penalty such as an insurance premium increase due to the unattached operation of the vehicle image storage device 300 is imposed. In other words, disadvantages such as non-payment of insurance benefits for accidents within that period may be provided.

Here, the first sensing information and the second sensing information include one or more of location information and environment information. The location information includes a GPS location sensed by the location information unit, and the environment information includes one or more of temperature, humidity, brightness, etc. detected by the environment sensor unit.

In this case, the sensing unit 220 may store the sensing information generated by performing a sensing operation at a predetermined cycle in the data storage unit 250. In this case, the first sensing information corresponding to the first time information may include sensing information stored at a time point according to the first time information, that is, a time point closest to the detachment time point (ie, sensing information generated by the sensing unit 220 before detachment or the like). Sensing information generated by the sensing unit 220 immediately after detachment, and the second sensing information corresponding to the second time information is the sensing information stored at a time point according to the second time information, i. The sensing information generated by the previous sensing unit 220 or the sensing information generated by the sensing unit 220 immediately after attachment.

However, in some cases, the sensing unit 220 may generate sensing information by performing a sensing operation in real time. In this case, the sensing unit 220 detects the detachment or attachment of the vehicle mounting apparatus 200 and performs the sensing operation. Information may be stored in the data storage 250.

In the above, the case in which the verification is performed in the vehicle mounting apparatus 200 has been described. However, the vehicle image storage device 300 uses the driving information received from the vehicle mounting apparatus 200 or the driving information generated therein as described below. To verify whether the vehicle has been used or not.

8 is a flowchart illustrating a process of providing driving information in an image storage device for a vehicle according to an exemplary embodiment of the present invention.

The vehicle image storage device 300 records an internal or external image of the vehicle according to a method previously specified in operation S510. In operation S520, the data processor 320 performs an encryption process on the recorded image and stores it in the data storage unit 330.

In operation S530a, the driving information transmitted through the first interface unit 340 is received from the vehicle mounting apparatus 200 to which the vehicle image storage device 300 is attached. In operation S540a, the driving information is encrypted and stored in the data storage unit 330.

Steps S510 to S520 and steps S530a to S540a may be independently performed.

In another embodiment, in step S530b, the vehicle information and / or the sensing information transmitted through the first interface unit 340 are received from the vehicle mounting apparatus 200 to which the vehicle image storage device 300 is attached. In operation S535b, driving information may be generated using vehicle information and / or sensing information. In operation S540b, the driving information is encrypted and stored in the data storage unit 330.

In this case, steps S510 to S520 and steps S530b to S540b may be independently performed.

After the encryption and storage of the driving information is performed, the vehicle image storage device 300 provides the driving information through the communication device or directly to the control center in step S550 and receives the decryption key information. This will be described later in detail with reference to FIGS. 9 and 10.

Using the decryption key information received in step S560, it is possible to decrypt and reproduce the encrypted data file, that is, the recorded video.

9 is a system configuration diagram illustrating a structure of transmitting driving information according to an embodiment of the present invention, and FIG. 10 is a flowchart illustrating a process of transmitting driving information according to an embodiment of the present invention.

As described above, the vehicle image storage device 300 according to the present embodiment performs a function of transmitting and driving information as well as a function for recording and storing an accident image. In addition, data files (i.e., image data and / or driving information) recorded and stored to induce transmission of driving information to the control center 520 are encrypted and stored, and the encrypted data file is controlled after transmission of driving information. Decryption processing is performed by decryption key information received from the center 520.

For example, the operation information may be received when the management program (management program), which will be described later, installed in the communication device 510 recognizes that the vehicle image storage device 300 is coupled, and decryption key information for reproducing the encrypted and stored data file. In order to access the control center 520, the user inputs a driving information transmission command by himself or herself, and the update time of the program installed in the vehicle image storage device 300 may be transmitted to the control center 520.

Although one control center 520 is illustrated in FIG. 9 as receiving the driving information and transmitting the decryption key information, the terminology collectively refers to one or more performing agents that perform the above-described operations collectively or partially or individually. Should be interpreted. In this case, the subject of each operation may be different.

If the vehicle image storage device 300 includes a communication unit capable of directly connecting to a wired / wireless network for transmission of driving information, the vehicle image storage device 300 may control driving information stored through the network to the control center 520. Can transmit and receive decryption key information.

However, if the vehicle image storage device 300 cannot directly access a network, the communication device 510 is connected to the communication device 510 (eg, at least one of a mobile communication terminal, a PDA, a computer device, etc.) by a communication cable, and the corresponding communication device. The stored driving information may be transmitted to the control center 520 and the decryption key information may be received using the communication function included in the 510.

In this case, a management program for processing such as reading the corresponding driving information and transmitting the same to the control center 520 may be installed in the vehicle image storage device 300 or / and the communication device 510.

In addition, if the data storage unit 330 is implemented to include a removable nonvolatile memory card, after detaching only the nonvolatile memory card and coupled to the reader (coupler) coupled to the communication device 510, the communication device 510 The management program installed in the CX may read the driving information stored in the nonvolatile memory card, transmit the driving information to the control center 520, and receive the decryption key information to be stored in the nonvolatile memory card.

Hereinafter, a process of transmitting driving information will be described with reference to FIG. 10. However, the case in which the vehicle image storage device 300 is connected to the communication device 510 through a communication cable and a management program installed in the communication device 510 reads and transmits driving information will be described.

The management program recognizes that the vehicle image storage device 300 is coupled to the vehicle image storage device 300 through a communication cable in step S610, and reads the encrypted serial number stored in the vehicle image storage device 300 in step S620 to control the center 520 through the network. To send).

The control center 520 decrypts the received encrypted serial number, determines whether the corresponding serial number is valid, and instructs transmission of driving information to the management program through the network when the serial number is valid.

The management program reads driving information stored in the data storage unit 330 of the vehicle image storage device 300 and transmits the driving information to the control center 520 through a network.

Thereafter, the decryption key information for decrypting the data file encrypted and stored in the vehicle image storage device 300 is received from the control center 520 and stored in an arbitrary storage unit of the vehicle image storage device 300 to store the encrypted data. Enable playback of the file. In order to induce the transmission of the driving information, the corresponding decryption key information may be generated such that only the encrypted data file generated before the time of transmitting the driving information after the previous driving information transmission can be decrypted and reproduced, for example.

The driving information transmitted to the control center 520 can be used as data on the premium differential calculation and payment, and can be used as the day of the week response information.

In addition, by receiving the verification information as well as the driving information, or by using the result of the verification using the operation information using the vehicle mounting device 200 is powered by other than the vehicle to operate or similar to the state inside the vehicle It can detect and judge the act of forging or tampering with driving information.

In addition, when the vehicle image storage device 300 is operated without being mounted on the vehicle mounting apparatus 200, penalties may be imposed due to unattached driving by using detachable information integrated in the driving information.

FIG. 12 is a cross-sectional view taken along line AA ′ and BB ′ of FIG. 11, and FIG. 13 is shown in FIG. 11. The male housing and the female housing are viewed from the direction of the arrow C.
