Description

The present invention relates to, for example, a system or the like.

In Patent Document 1, regarding inventions relating to in-vehicle devices and systems (paragraph [0001], etc.), paragraph [0055] states, "When the power supply from the ACC power supply is cut off, the monitoring battery provides a power supply source to the drive recorder. "Switch from the vehicle to the internal battery and continue to supply power to the drive recorder." Also, in paragraph [0076], "My area" is set to "Manual" for "Recording mode". Even in this case, it is an area where surveillance recording is automatically performed. The "my cancel area" is an area in which surveillance recording is not automatically performed even when the "recording mode" is set to "automatic". For example, if a user registers an unsecured home parking lot in "My Area" and parks in the home parking lot, the user can automatically perform surveillance recording. "My Cancel Area" has a configuration that can be registered in advance in "Settings". Further, for example, if the user registers a secure parking lot at work in the "My Cancel Area", the user can not perform surveillance recording at the parking lot at work. ".

JP-A-2017-195755

For example, when monitoring recording is performed or not performed while parking, it may be complicated because it is necessary to change the registered contents of the setting. For example, when the vehicle is stopped and the ACC is turned off, if there is a driver who wants to get off early, the system that requires the change of the registered contents of the setting may not be able to satisfy the driver's request. Further, for example, when the driver parks and disembarks the vehicle, he / she may want to activate / suppress an appropriate parking monitoring function while disembarking without having to switch the troublesome setting.

Conventionally, monitoring during parking is uniform, such as whether or not to record surveillance. For example, parking monitoring according to the vehicle status such as the remaining battery level, the parking place, the surrounding conditions, the parking time, etc. I can't. One of the objects of the present invention is to solve such a problem regarding surveillance recording during parking.

By the way, among the recorded data of the drive recorder, there is a problem that it is difficult to know where the recorded data during driving in a state where an accident is likely to occur (so-called hiyari hat) is recorded. Since the current drive recorder specializes in recording in the event of an accident, when there is a large impact that the G sensor exceeds the threshold value, it is saved with increasing importance as event recording (also called event recording). doing. However, if the user does not instruct the event button recording in a state where an accident is likely to occur (hiyari hat), the image at the time of the hiyari hat will be buried in the image of the normal recording, and it may be difficult to understand later. Therefore, it is troublesome to look back on the hiyari hat driving with a video. Therefore, one of the other objects of the present invention is to solve such a problem related to recording during driving.

The above-mentioned problems are described as independent ones, and the present invention does not necessarily have to be able to solve all of the described problems. The object of the invention of the present application is not limited to this, and there is an intention to acquire rights by divisional application, amendment, etc. for a configuration for the purpose of obtaining an effect produced from a portion of the configuration disclosed in the present specification, drawings, etc. .. For example, the present specification discloses a problem in which the part described as "can be" is replaced with "is a problem" in the present specification. The issues are described as independent, and we have the intention to independently acquire the rights to the structure for solving this issue by divisional application, amendment, etc. Even if the subject matter is implicitly grasped from the description in the specification, the applicant intends to make a part of the structure described in the specification amended or to be claimed in the divisional application. In addition, issues that combine these independent issues are also disclosed.

(1) A parking monitoring function for recording an image taken at a parking position and a function for setting a parking position for suppressing the operation of the parking monitoring function are provided, and the parking monitoring function parks at the set parking position. Even if it is done, if the predetermined conditions are satisfied, the video may be recorded.

When a predetermined condition is satisfied, the image taken at the parking position is recorded while maintaining the setting of the parking position that suppresses the operation of the parking monitoring function. Since the setting of the parking position for which recording is not performed is maintained, if the parking position is subsequently parked in the set parking position without satisfying the predetermined conditions, the operation of the parking monitoring function is suppressed. For example, when a driver parks a vehicle and gets off the vehicle, he / she wants to activate / suppress an appropriate parking monitoring function while getting off the vehicle without performing a special operation (for example, switching a troublesome setting). it can.

(2) Suppressing the operation of the parking monitoring function may mean that the video is not recorded. In this way, the parking monitoring function does not record an image when the vehicle is parked at the set parking position. By setting an appropriate parking position in advance, when the vehicle is parked and disembarked, parking monitoring can be performed at a desired position, and parking monitoring cannot be performed at the set parking position. Since the parking position setting has not changed, no parking record is recorded when parking at that parking position after that. Therefore, it is possible to ensure that parking is not recorded in a place where parking recording is not normally required.

(3) Even when the parking monitoring function is parked at a position other than the set parking position, it is preferable to suppress the operation of the parking monitoring function when a predetermined condition is satisfied. When the vehicle is parked at a position other than the set parking position, the parking monitoring function records the image taken at the parking position, but when a predetermined condition is satisfied, the operation of the parking monitoring function is suppressed. For example, since the parking position is suppressed without setting the parking position, the next time the vehicle is parked, the parked image can be recorded without any special operation.

(4) The parking monitoring function has a function of setting a parking position for recording a parked image and a parking monitoring function for recording a captured image when the vehicle is parked at the set parking position. Even when the vehicle is parked at the set parking position, it is advisable to suppress the recording of the image when the predetermined conditions are satisfied.

In this way, when the vehicle is parked at the set parking position, the parked image can be recorded even if the vehicle gets off. When a predetermined condition is satisfied, it is possible to suppress the recording of the image while maintaining the setting of the parking position for recording the image during parking. In this case, the setting of the parking position is maintained. Therefore, if the vehicle is subsequently parked at the parking position under the setting without satisfying the predetermined conditions, the parked image is recorded. As a result, for example, when the driver parks and disembarks the vehicle, he / she can activate / suppress the appropriate parking monitoring function while disembarking without performing a special operation (for example, switching of troublesome settings). Can be done.

(5) The parking monitoring function may record a parked image if a predetermined condition is satisfied even when the vehicle is parked at a position other than the set parking position. In this way, it is possible to record an image taken when the vehicle is parked at a position other than the parking position being set, without changing the setting. Since the parking position setting has not been changed, the next time the parking is parked, the parking is not recorded without any particular operation.

(6) The predetermined condition may be based on the operation when the vehicle is parked at the parking position. In this way, when the vehicle is parked in the parking position, when the vehicle is parked in the set parking position, the parking monitoring can be operated differently from the setting.

(7) It is preferable to have a function of changing the light emitting state of the light emitting unit based on the above operation. In this way, for example, by checking the light emitting state when the user operates, it is possible to visually determine whether or not the current state satisfies a predetermined condition. For example, if the user cannot operate or performs a different operation, the system can be made to perform the desired operation by re-operating.

(8) It is assumed that the predetermined condition is satisfied when the predetermined condition is not satisfied by the operation so as to switch whether or not the predetermined condition is satisfied, and when the predetermined time elapses after parking, the operation is performed. Then, it is preferable to extend the predetermined time and determine whether or not the predetermined condition is satisfied by the lapse of the extended time.

By doing so, even if there is an erroneous operation, the predetermined time is extended by the operation, so that a sufficient time can be secured to perform the correct operation again when an unintended operation is performed. In addition, if the correct operation is performed, the content is determined based on the last operation after a predetermined time elapses, so that a separate operation for confirming the content is not required, and the time and effort of the user's operation can be reduced. You can get off quickly.

(9) It is preferable to have a function of switching whether or not the predetermined condition is satisfied or not according to an operation different from the operation, and a function of updating the setting related to the parking position. In this way, it is possible to easily select whether to perform an operation different from the setting only this time without changing the setting at the parking position, or to update the setting and perform the same operation as this time from the next time onward.

(10) It is preferable that the display unit is provided and the predetermined condition is based on the operation of the display unit on the screen when the vehicle is parked at the parking position. A predetermined condition can be easily satisfied by operating the screen of the display unit.

(11) It is preferable to have a function of confirming that the predetermined condition is satisfied when the operation on the screen is performed. By doing so, the predetermined conditions can be satisfied at an early stage, and the driver can get off immediately. By looking at the display, there is less risk of making mistakes such as pressing mistakes, so we decided to improve convenience by confirming immediately.

(12) It is preferable that the display unit simultaneously displays the first area operated to satisfy the predetermined condition and the second area operated to update the setting regarding the current parking position. By doing so, it is possible to easily instruct whether to perform an operation different from the setting only this time without changing the setting at the parking position, or to update the setting and perform the same operation as this time from the next time onward.

(13) A function that includes a display unit and displays the battery voltage of the vehicle on the display unit when the power source for supplying power to the system is a vehicle battery, and does not display the battery voltage when another power supply device is used. You should prepare. In this way, when the power is supplied from the battery of the vehicle, the battery voltage is displayed, so that the user can recognize the state of the battery, for example, and decide whether or not to monitor the parking. Also, the type of power supply can be recognized from the presence or absence of the display of the battery voltage.

(14) The connection control device including a first device having a function of recording the video, a second device having the display unit, and a connection control device for connecting the first device and the second device. Is a function of supplying power to the first device and the second device based on the power supplied from the connected power source, a communication control function for communicating between the first device and the second device, and the first device. It is preferable to have a power supply control function for controlling ON / OFF of the power supply supplied to one device and the second device. In this way, the connection control device can control power supply, communication, and power ON / OFF to each of the first device having a function of recording video and the second device having a display unit. it can.

(15) A connection control device for connecting a first device having a function of recording an image by any of the above parking monitoring functions and a second device displaying a screen related to the parking monitoring function, which is supplied from a power source. A function of supplying power to the first device and the second device, a communication control function for communicating between the first device and the second device, and the first device and the second device based on the electric power. This is a connection control device including a power supply control function for controlling ON / OFF of the power supply to be supplied. In this way, the connection control device can control at least one of power supply, communication, and power ON / OFF to each of the first device and the second device.

(16) The program according to the present invention may be a program for realizing the function in the system according to any one of (1) to (14) or the function of the connection control device of (15) in a computer.

(17) Further, the present invention may be specified by a system having a function of determining the state of the driver of the vehicle and a function of recording an event according to the state of the driver. In this way, recording can be automatically performed according to the state of the driver of the vehicle.

The inventions (1) to (17) described above can be arbitrarily combined. For example, the configuration may be such that at least a part of the configuration of at least one invention after (2) is added to all or part of the configuration of the invention shown in (1). In particular, the invention shown in (1) may be an invention in which at least a part of at least one of the inventions after (2) is added. The applicant of the present application intends to acquire a patent right, a design right, etc. by an amendment, divisional application, change application to a design registration application, etc., even for those including these configurations.

According to the present invention, for example, at least one of the following effects is exhibited. If the specified conditions are met while maintaining the parking position setting, such as suppressing the operation of the parking monitoring function or recording the video taken during parking, for example, the parking position is temporarily set. It is possible to perform the same processing as in the place where it is not. Since the parking position setting is maintained, if you subsequently park at the parking position under the setting without satisfying the prescribed conditions, you can perform the originally set processing without any special operation. it can. For example, when the driver parks and disembarks the vehicle, he / she can properly activate / suppress the parking monitoring function while disembarking without having to switch the troublesome setting.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. These drawings are used to illustrate the technical features that can be adopted by the present invention. The configuration, shape, etc. of the device described are merely explanatory examples, and the present invention is not construed as being limited thereto, and is based on the knowledge of those skilled in the art as long as it does not deviate from the scope of the present invention. , Various changes, modifications and improvements can be made.

[Basic configuration of one embodiment of the system]
FIG. 1 shows a preferred embodiment of a drive recorder system, which is a form of a device having a parking monitoring function for recording an image taken during parking. The system 1 of the present embodiment includes a drive recorder 2 and a power supply device 3 that supplies power to the drive recorder 2.

In this embodiment, the drive recorder 2 is a device that is installed later on the vehicle. The drive recorder 2 of the present embodiment has a drive recorder function of photographing and recording a predetermined area around the vehicle when traveling, for example, by photographing a predetermined area such as the front of the vehicle or the interior of the vehicle when parking. It has a parking monitoring function to record. In order to realize this parking monitoring function, the system 1 drives even when the ignition switch is OFF, that is, the ACC (accessory power supply) is OFF and the power supply from the vehicle battery is not received, such as when the vehicle is parked. The recorder 2 operates by receiving electric power from a power supply device 3 prepared separately from the vehicle.

The power supply device 3 is a device that is interposed between the vehicle and the drive recorder 2 to supply power to the drive recorder 2. The power supply device 3 is composed of a housing different from that of the drive recorder 2. The power supply device 3 includes a charge / discharge control unit 3a, a DC-DC converter 3b, a CPU 3c, an internal battery 3d, and the like. The charge / discharge control unit 3a controls charging of the internal battery 3d and power supply to the drive recorder 2. The internal battery 3d is a secondary battery, which is realized by, for example, a nickel hydrogen rechargeable battery. The DC-DC converter 3b converts the voltage of 12V or 24V supplied from the battery of the vehicle into a voltage of 5V and outputs the voltage via the charge / discharge control unit 3a. The CPU 3c uses a memory (for example, RAM) (not shown) as a work area to control each part of the power supply device 3 such as the charge / discharge control unit 3a. Further, the CPU 3c communicates with the drive recorder 2 connected via the cable 4. The cable 4 includes a power supply line and a communication line.

The charge / discharge control unit 3a receives power from the internal battery 3d. The charge / discharge control unit 3a controls the power supply path so as to supply power from the vehicle battery to the internal battery 3d and the DC-DC converter 3b while the power is being supplied from the vehicle battery. As a result, the internal battery 3d is charged, and the DC-DC converter 3b supplies the voltage-converted electric power to the drive recorder 2. The charge / discharge control unit 3a determines ON / OFF of the ACC of the vehicle and switches whether to charge or discharge the internal battery 3d. When the charge / discharge control unit 3a determines that the ACC is ON, the charge / discharge control unit 3a controls to supply power from the vehicle battery to the internal battery 3d and the DC-DC converter 3b. When the charge / discharge control unit 3a determines that the ACC is OFF, the charge / discharge control unit 3a controls to discharge the internal battery 3d and supply power from the internal battery 3d to the DC-DC converter 3b.

As described above, the power supply device 3 receives power from the vehicle battery and outputs electric power to the drive recorder 2 during the period when the ACC is ON. When the power supply from the vehicle battery is cut off, the electric power is output to the drive recorder 2 by using the internal battery 3d for a specified time after the cutoff. When the specified time elapses, the power output is turned off. When the supply of electric power from the vehicle battery is resumed, the electric power is output to the drive recorder 2 again using the vehicle battery.

As a result, the drive recorder 2 can continue to operate for a specified time after the ACC is turned off and the power supply from the vehicle battery is cut off. The specified time may be set by, for example, serial communication from the drive recorder 2. When the drive recorder 2 receives the battery switching signal from the power supply device 3, it transmits a signal instructing a specified time. The CPU 3c may set a specified time set value included in the signal for instructing the specified time to be received as the specified time.

Further, it is preferable that the power supply device 3 is provided with a DIP switch or other operation unit to have a function of setting a specified time. In this way, for example, even a drive recorder having no communication function can be supplied with power until a predetermined time elapses after the supply by the vehicle battery is cut off.

When the power supply from the vehicle battery is cut off, the power supply device 3 switches the power supply source to the internal battery 3d and supplies power to the drive recorder 2. Since the drive recorder 2 continues to be supplied with power before and after the switching, the drive recorder 2 cannot determine whether the power supply source is the vehicle battery or the internal battery 3d. Therefore, when the power supply source is switched to the internal battery 3d, the CPU 3c transmits a battery switching signal to the drive recorder 2. If the ACC is turned on after the power supply device 3 turns off the output after the specified time has elapsed, the drive recorder 2 restarts the power supply that had been stopped, so that it can be determined that the ACC has been turned on. .. On the other hand, when the ACC is turned on within the specified time, the drive recorder 2 continues to be supplied with power, so it is not possible to determine whether the power supply source is the vehicle battery or the internal battery 3d. Therefore, when the ACC is turned on within the specified time, the CPU 3c transmits a vehicle switching signal notifying that the power supply source has been switched to the battery of the vehicle. As a result, the drive recorder 2 can recognize that the ACC is turned on and the power supply source is switched to the battery of the vehicle. As will be described later, the drive recorder 2 switches the operation mode according to the input of the battery switching signal and the vehicle switching signal.

The drive recorder 2 of this embodiment has a function of recording and outputting an omnidirectional image obtained by photographing 360 degrees in a horizontal plane and 360 degrees in a vertical plane. As shown in FIGS. 2 to 4, the drive recorder 2 includes a main body 11 that executes various processes, and a camera unit 12 that is arranged below the main body 11 in a vehicle-mounted state. The drive recorder 2 is not limited to the one that captures and records the spherical image. The drive recorder 2 may capture and record at least one of the front, rear, and side of the vehicle.

The main body 11 has a flat rectangular main body case 13, and various circuit boards and devices are mounted in the main body case 13. The main body case 13 is configured by connecting the first case 14 and the second case 15. The first case 14 and the second case 15 are box-shaped with their facing surfaces open to each other, and are connected by connecting means in a state where their tip surfaces are in contact with each other. For example, the connecting means may include protrusions provided on one of the first case 14 and the second case 15 and recesses provided on the other side, which are linked to the protrusions, and the protrusions and the recesses may be fitted together.

The first case 14 has a shallow bottom, the peripheral edge of the opening surface is substantially rectangular, and the four corners are rounded, and the depth is substantially uniform throughout. When the drive recorder 2 is installed in the vehicle, the first case 14 is located on the front side of the vehicle. Therefore, the surface of the first case 14 opposite to the opening surface is the front surface 13a of the main body case 13. A joint rail 16 is provided on the front surface 13a. Two joint rails 16 are provided vertically at predetermined intervals along the longitudinal direction of the first case 14. A bracket 17 is detachably attached between the two joint rails 16.

The second case 15 has a box shape deeper than that of the first case 14, and the peripheral edge of the opening surface has a substantially rectangular shape with rounded squares as in the first case 14. When the drive recorder 2 is installed in the vehicle, the second case 15 is located on the rear side of the vehicle. Therefore, the surface of the second case 15 opposite to the opening surface is the rear surface 13b of the main body case 13. The portion of the rear surface 13b adjacent to one of the pair of long sides of the rectangle is a flat surface 13b', which is a plane parallel to the front surface 13a of the main body case 13, and the portion adjacent to the other of the pair of long sides is an inclined surface 13b. The inclined surface 13b ″ is formed so as to gradually approach the opening surface of the second case 15 from the middle side of the short side toward the long side on the outside.

Therefore, the depth of the second case 15 is uniform in the region including the flat surface 13b', and is formed so as to gradually become shallower toward the long side in the region including the inclined surface 13b ". The appearance shape of the main body case 13 is such that one long side portion is chamfered based on a rectangular parallelepiped. One long side to be chamfered is the rear upper side of the vehicle with the drive recorder 2 installed in the vehicle. When the first case 14 and the second case 15 are connected, the front surface 13a on the first case 14 side and the flat surface 13b'on the second case 15 side are parallel.

A recess 15b arranged so as to extend in the vertical direction is provided at a predetermined position on the surface opposite to the opening surface of the second case 15, which is the rear surface 13b of the main body case 13. The recess 15b has a shallow bottom, and its inner surface is located at a position one step deeper than the surface of the second case 15. In addition, most of the recess 15b is located on the flat surface 13b'of the rear surface 13b of the main body case 13, the upper end of the recess 15b is located on the inclined surface 13b ", and the upper end edge is opened in the recess 15b. The LED 36, the first button portion 37, and the second button portion 38 are arranged in this order from the top. The height of the first button portion 37 and the second button portion 38 is made higher than the depth of the recess 15b, and the first button is arranged. The surfaces of the portion 37 and the second button portion 38 project slightly outward from the surface of the second case 15 (that is, the flat surface 13b').

The LED 36 is an example of a light emitting body. The light emitting state of the LED 36 changes according to the operating state of the drive recorder 2. The light emitting state may be specified by, for example, one or more of the presence / absence of light emission, the light emission color, and the light emission timing. In the present embodiment, the first button unit 37 and the second button unit 38 are operation means for accepting a push operation (push operation). For example, the function of the start button is assigned to the first button portion 37 located on the upper side. If the first button portion 37 is pressed while recording is stopped, recording is resumed. For example, a stop button function is assigned to the second button portion 38 located on the lower side. If the second button portion 38 is pressed and held during recording, recording is stopped.

The bracket 17 has a flat plate 17a, and grooves 17b are formed along the longitudinal direction on a pair of side surfaces of the long sides thereof. The groove 17b is configured to match the joint rail 16. The user aligns the groove 17b with the joint rail 16 and slides the bracket 17 and the main body case 13 relative to each other so that the bracket 17 can be attached to or detached from the main body case 13.

An adhesive member such as double-sided adhesive tape 19 is attached to the surface of the bracket 17 opposite to the surface facing the main body case 13. When the drive recorder 2 is attached to the vehicle, it is attached and fixed to the windshield 5 of the automobile via the double-sided adhesive tape 19 (see FIG. 4A and the like). In this mounted state, the front surface 13a and the flat surface 13b'of the main body case 13 are arranged parallel to the mounting surface of the front glass 5, the long side of the main body case 13 is located in the horizontal plane, and the short surface of the main body case 13 is short. The side surface is located in the vertical plane. Therefore, the main body case 13 is fixed in a horizontally long state while being attached to the windshield 5, and the camera unit 12 is arranged in a state of being suspended from the bottom surface side of the main body case 13.

A notched window portion 14a is formed on one short side side of the first case 14, and a cover member 20 for closing the notched window portion 14a is attached. The cover member 20 is fastened and fixed with screws 21 in a state where the notched window portion 14a is arranged so as to close the cutout window portion 14a. When the cover member 20 is removed, the card slot 22 mounted in the main body case 13 is exposed through the notched window portion 14a. A memory card 23 such as a micro SD card or an SD card is detachably mounted in the card slot 22. The memory card 23 corresponds to a recording medium on which video is stored. The card slot 22 corresponds to a mounting portion in which the memory card 23 is mounted.

A window hole 15a is provided in the second case 15 on the same side surface as the side on which the notched window portion 14a is provided, and the female connector 24 is arranged behind the window hole 15a. A male connector 4a provided at one end of the cable 4 is attached to the female connector 24. The cable 4 of this embodiment includes a power supply line and a communication line, and the drive recorder 2 receives power from an external power source or communicates with an external device via the cable 4. ..

On the other hand, the camera unit 12 includes a housing 25, a first camera 26 and a second camera 27 mounted in the housing 25, and a recording button 28. The housing 25 has a spherical shape as a whole, and is configured by connecting the hemispherical first camera case 25a and the second camera case 25b, which are divided into two, in a state of being attached to each other. The fixing of the first camera case 25a and the second camera case 25b is provided in, for example, one of the first camera case 25a and the second camera case 25b in the same manner as the fixing of the first case 14 and the second case 15 described above. It is preferable to use the fitting of the protrusion and the recess provided on the other side.

The first camera 26 and the second camera 27 may be arranged back to back, and may be fixed and connected so as to shoot in opposite directions to form a camera unit. Then, the optical axis L of the lens portion, which is one of the constituent elements of the first camera 26, and the optical axis L of the lens portion, which is one of the constituent elements of the second camera 27, are set to be located on the same straight line.

The housing 25 of the camera unit 12 is connected to the main body case 13 via the angle adjusting mechanism 29. The angle adjusting mechanism 29 allows the housing 25 to swing in the front-rear direction by rotating the housing 25 only around the rotation axis provided along the long side on the front side of the bottom surface of the main body case 13 (see FIG. 4). , Do not shake it sideways. For example, the housing 25 is rotatably mounted around the axis of the bolt with respect to the bolts arranged in parallel along the long side at a predetermined position in the main body case 13, and the nut 29a is attached to the male screw portion of the bolt. The nut 29a is arranged in the inner part of the hole 13c provided on one side surface of the main body case 13, and for example, a tool such as a hexagon wrench is inserted into the hole 13c and matched with the nut 29a to match the hexagon wrench or the like. The nut 29a is tightened or loosened by rotating the tool in the forward and reverse directions. Then, when the nut 29a is loosened, the housing 25 of the camera unit 12 rotates in the forward and reverse directions and swings in the front-rear direction. Further, when the nut 29a is tightened in an appropriate posture by swinging the head, the angle and the direction of the camera unit 12 are fixed in that posture.

The recording button 28 is arranged at the center of the lower end of the housing 25, and its surface shape is substantially circular in a plan view, and is formed on a curved surface whose radius of curvature is substantially equal to the radius of the housing 25. For example, when the recording button 28 is pressed, manual recording is performed, and as one-touch recording, images for a predetermined period before and after the pressing are recorded on the memory card 23. For example, if the record button 28 is pressed during continuous recording for constantly recording a video captured during traveling, for example, a file different from the file for continuous recording is pointed out and recorded. A recording lamp is built in the back surface and the back surface side of the recording button 28, that is, inside the housing 25. This recording lamp notifies the recording status by lighting.

Various processing circuits, devices, parts, and the like are further mounted in the main body case 13. That is, in the main body case 13, for example, the first control unit 31, the second control unit 32, the sound output unit 33, the microphone 34, the position information storage unit 35, the abnormality detection sensor 39, the GPS receiver 40, the power supply unit 41, and the like. It is provided with a communication interface 42 and the like.

The first control unit 31 mainly operates to realize the parking monitoring function, and the second control unit 32 mainly operates to realize the drive recorder function. The power consumption of the second control unit 32 is larger than the power consumption of the first control unit 31. Therefore, during parking when the parking monitoring function operates, the operation of the second control unit 32 is normally turned off and the power supply is turned off to suppress the power consumption of the internal battery 3d of the power supply device 3 for a long time. Enables operation. The function of each control unit will be described later.

The microphone 34 collects sounds around the drive recorder 2. The microphone 34 collects, for example, the voice of a person in the vehicle, other sounds generated in the vehicle interior, and the impact sound when an object collides with the vehicle. The microphone 34 corresponds to a sound collecting means. The sound output unit 33 is, for example, a speaker or a buzzer, and outputs a predetermined sound at a predetermined recording time, an alarm time, an operation time, or the like. The card slot 22 is a device that reads / writes data to / from the installed memory card 23. For example, the image taken by the camera unit 12 and the sound collected by the microphone 34 are recorded in the memory card 23. The GPS receiver 40 has a function of receiving a GPS signal and acquiring position information, date and time information, and speed information from the GPS signal.

The position information storage unit 35 is composed of a non-volatile memory. The position information storage unit 35 includes, for example, a final positioning position storage area that stores and holds the final positioning position determined by the GPS receiver 40, and the second control unit 32 finally positions the position information output from the GPS receiver 40. It is stored in the position storage area and rewritten and updated.

Further, the parking monitoring function of the present embodiment includes a cancel function that does not record when the vehicle is parked in the registered "cancellation area". If this "cancellation area" is, for example, a circular area with a predetermined radius (for example, 50 m) centered on the parking position registered as a point, the actual parking is performed only by storing the parking position information that specifies the parking position. It is good because it can be determined whether or not the position is in the cancellation area. The position information storage unit 35 includes a parking position storage area for storing parking position information for realizing the cancel function. Details of this cancel function will be described later.

The abnormality detection sensor 39 is, for example, an acceleration sensor or a 6-axis sensor (3-axis acceleration, 3-axis angular velocity integrated type), and detects a vehicle state such as an impact applied to the vehicle, vehicle acceleration, and inclination. The abnormality detection sensor 39 is not limited to the above-exemplified one, and may be, for example, a Doppler sensor for detecting the approach of an object, an approach sensor, or any other event that triggers recording of various images.

The power supply unit 41 has a function of supplying a power supply voltage to, for example, a device included in the drive recorder 2 and operating the power supply unit 41. The power supply unit 41 is electrically connected to the terminal of the power supply line of the female connector 24, receives the power supplied from the power supply device 3, and has a desired voltage value for each device mounted on the main body case 13. Supply power supply voltage.

The communication interface 42 is connected to the terminal of the communication line of the female connector 24. Communication is performed between the CPU 3c of the power supply device 3 and the first control unit 31 and / or the second control unit 32 of the drive recorder 2.

The first control unit 31 and the second control unit 32 are microcomputers each including a CPU, ROM, RAM, non-volatile memory, I / O, and the like, and are connected to the above-described units as shown in FIG. The function of the drive recorder 2 of the present embodiment is realized, for example, by being stored in the NAND Flash memory of the control unit as firmware to be executed by the CPU of the control unit, and being executed by the CPU of the control unit. The firmware stored in the NAND Flash memory can be updated by the new firmware stored in the memory card 23.

The first control unit 31 and the second control unit 32 may independently or collaborate with the above-mentioned various input devices (for example, camera unit 12, microphone 34, position information storage unit 35, first button unit 37, second button). The operation of the output device (for example, the card slot 22, the position information storage unit 35, the LED 36, etc.) is controlled based on the information input from the unit 38, the abnormality detection sensor 39, the GPS receiver 40, etc., and the predetermined information, etc. Is output. The second control unit 32 accesses, for example, the position information storage unit 35 to read and write, and controls the GPS receiver 40 to acquire position information and the like.

When the engine-started ACC is ON, both the first control unit 31 and the second control unit 32 start and operate, and record, for example, video data taken by the camera unit 12 and audio data collected by the microphone 34. To do. This recording is to record the video and audio for a certain period of time before and after the event occurs as separate data when the event conditions are met, while the continuous recording is performed, for example, when the vehicle is running, such as when the engine is starting. Good. Both the constantly recorded data and the separate data when the event occurs are recorded in the memory card 23. In addition, when continuous recording is not performed, the second control unit 32 constantly temporarily records video and audio for a certain period of time in a buffer memory or the like, and when the event conditions are met, the temporarily recorded data or the like is used. Is used to record video and audio for a certain period of time before and after the event occurs on the memory card 23.

Further, while the vehicle is parked with the engine stopped (ACC is turned off), the vehicle operates in the parking monitoring mode and records video data and the like taken by the camera unit 12 in accordance with the set operating conditions on the memory card 23. Recording in the parking monitoring mode is, for example, continuous recording in which an image taken at a predetermined recording time (for example, 30 minutes) is constantly recorded, or video data is continuously recorded for a predetermined time when an abnormality is detected by the abnormality detection sensor 39. There are event recordings to be recorded. Event recording includes, for example, "detecting that a person or vehicle is approaching", "detecting an impact above a certain level", "detecting an inclination of a vehicle above a certain level (for example, jacking up)", and "opening the vehicle door". Performed when event conditions such as "detection" are met. The abnormality detection sensor 39 includes one or a plurality of sensors for detecting them.

After the recording time of continuous recording has elapsed, it is preferable to automatically switch to event recording and continuously perform parking monitoring. In addition, when a predetermined event condition is satisfied during constant recording, it is preferable to record the video at a predetermined time before and after the event occurrence as a separate file as an event recording.

When recording an event, the camera unit 12 stops operating when there is no operation trigger during parking. For example, when a moving object such as a person or a vehicle is detected in the detection area of the area sensor using microwaves, the camera unit 12 is used. 12 is started, the camera unit 12 is operated for a predetermined camera standby time to take a picture, and then the operation of the camera unit 12 is stopped. Then, when the predetermined event condition is satisfied during the camera standby time, the video captured at the predetermined time before and after the occurrence of the satisfied event is recorded on the memory card 23.

The parking monitoring mode may be activated, for example, by an operation trigger after the vehicle engine is turned off (ACC OFF). The operation trigger may include a "manual" that shifts based on a manual operation, an "ACC OFF interlocking" that automatically shifts when the ACC is turned off, and the like. Switching between "manual" and "ACC OFF interlocking", switching of parking monitoring mode recording methods ("constant recording + event" and "event only", etc.), various recordings, operating time, etc. are, for example, various modes. It is good to do it by setting operation.

During operation in this parking monitoring mode, the first control unit 31 controls the control, the second control unit 32 is activated as necessary and operates in cooperation with the first control unit 31, and then the second control unit 32. 32 is turned off. For example, since the second control unit 32 performs the function of acquiring the current position based on the GPS receiver 40, the second control unit 32 is activated when acquiring the current position, and the first control unit 31 is the second control unit. The position information is acquired from 32. The second control unit 32 controls the operation of, for example, the abnormality detection sensor 39 that is activated during the operation of the parking monitoring mode.

[Cancellation area setting for parking recording in the cancel function]
As described above, the drive recorder of the present embodiment has the above-mentioned cancel function that does not record parking when the parking position is in the registered cancellation area. In this embodiment, the cancellation area is registered by registering the parking position as a point. Then, a predetermined range (for example, 50 m) around the memorized point is set as the cancel area. Not recording parking is an example of suppressing the operation of the parking monitoring function.

The point registration is performed when the predetermined operating means is operated while the drive recorder 2 is operating while the vehicle is parked at the parking position to be registered. In this embodiment, when the engine is stopped (ACC is OFF), the cancel area is set or set based on the push operation of the first button portion 37 and the second button portion 38 performed within a certain period of time. It has a function to delete the canceled area. As an example, when the vehicle is stopped in a place other than the cancellation area and the engine is turned off, the first control unit 31 turns on the LED 36, which is a power lamp, in red as shown in FIG. 5A-1. The sound output unit 33 outputs a sound of "piro-piro-piro". When the first button unit 37 and the second button unit 38 are pressed at the same time within a predetermined time (for example, 10 seconds) after outputting this sound, the second control unit 32 follows the instruction from the first control unit 31. The parking position information that specifies the current position is registered in the parking position storage area of the position information storage unit 35, and after registration, the first control unit 31 blinks the LED 36 in orange as shown in FIG. 5A-2. Outputs a beeping sound from the speaker.

On the other hand, when the vehicle is stopped at a place in the cancel area and the engine is turned off, the first control unit 31 turns on the LED 36, which is a power lamp, in orange as shown in FIG. 5 (b-1), and outputs sound. A beeping sound is output from the unit 33. When the first button unit 37 and the second button unit 38 are pressed at the same time within a predetermined time (for example, 10 seconds) after outputting this sound, the second control unit 32 is currently in accordance with the instruction from the first control unit 31. The cancel area of the position is released, and after the release, the first control unit 31 blinks the LED 36 in red as shown in FIG. 5 (b-2) and outputs a “piro-piro-piro” sound from the speaker.

In this way, the first control unit 31 registers and cancels the cancel area when the first button unit 37 and the second button unit 38 are pressed at the same time while a predetermined time has elapsed after the ACC is turned off. Are alternately transitioned and restarted for a predetermined time. In this embodiment, the second control unit 32 updates the stored contents of the position information storage unit 35 with the determination of the first control unit 31. Then, the first control unit 31 determines in the final state when there is no button operation for a predetermined time. Therefore, for example, if the current state at the parking position (for example, whether or not the cancellation area is set) can be left as it is, the user can get off the vehicle as it is and operate as set. By pressing the one-button unit 37 and the second button unit 38 at the same time, it is possible to set the desired setting for the presence or absence of the cancel area.

Conventionally, registration or cancellation of this type of cancellation area is performed by setting the mode while the drive recorder is operating. Therefore, for example, if you want to monitor parking this time after turning off the engine in the cancel area, turn on the engine, turn on the drive recorder 2, delete the cancel area in the mode setting, and then again. It was necessary to turn off the engine, which was sometimes very troublesome. Similarly, if you want to monitor parking this time when you can check the mode by turning off the engine outside the cancellation area, you need to turn on the engine again to drive the drive recorder and change the setting. , Sometimes very complicated.

On the other hand, in the present embodiment, the current setting (for example, inside / outside the cancel area) can be switched by button operation (for example, simultaneous pressing) after the engine is turned off, so that the cancellation area can be easily registered or canceled. And it can be done smoothly.

The drive recorder 2 of the present embodiment does not include, for example, a display unit for displaying an image captured by the camera unit 12 or displaying a setting screen for making various settings. Therefore, for example, it is not possible to display and show the current situation such as whether or not the current position is within the cancel area. Therefore, in this embodiment, the light emitting state (for example, the light emitting color) of the LED 36 is changed and the output sound is also changed depending on whether the current position is inside or outside the cancel area. As a result, the user can confirm the current setting status by checking, for example, the emission color of the LED 36 or listening to the content of the notified sound. Therefore, when the user parks and gets off, he / she checks the color of the LED, determines whether the color is the desired color, and if they are different, presses both buttons at the same time to switch the setting.

As described above, in the present embodiment, the cancellation area is registered and canceled alternately by simultaneously pressing the first button portion 37 and the second button portion 38. Therefore, for example, in the cancel area, the cancel area can only be canceled, and in this embodiment, the parking position information can only be deleted, and additional registration cannot be performed for the same position or a position within a distance r from the registered point. As a result, for example, multiple parking position information is not registered in the same parking lot, and one representative central point is registered. Therefore, the memory capacity can be reduced and the cancellation area can be registered in different places. You can do many things.

As the registration point of the cancellation area, the final positioning point that is sequentially updated between the time when the ACC is turned on and the time when the ACC is turned off is used. As a result, even when parking in a place where GPS signals cannot be received and positioning is not possible, for example, in an underground parking lot, registration can be performed using the final positioning point such as an entrance. Similarly, when determining whether or not the area is a cancellation area, the second control unit 32 may access the final positioning position storage area according to the instruction from the first control unit 31 and make a determination based on the acquired position information.

In this way, even when parking in a place where positioning is not possible, such as an underground parking lot, the final positioning position is used to determine whether the area is a cancellation area, and the user who has set the operation of monitoring / not parking in the drive recorder. Can be executed with the desired content. For example, in the case of an underground parking lot, positioning may not be possible near the entrance of the parking lot, so the position information measured near the entrance is recorded and held in the final positioning position storage area. When setting the underground parking lot as the cancellation area, if the cancellation area is set while the vehicle is stopped in the underground parking lot, it is set based on the position information near the parking lot entrance stored in the final positioning position storage area at that time. To do. Therefore, even if GPS cannot be positioned when parking in the underground parking lot at a later date, it can be correctly determined to be in the cancellation area based on the position information stored in the final positioning position storage area (for example, near the parking lot entrance).

Also, for example, even if the engine is started in the underground parking lot, positioning is not possible, and even if the engine is stopped and parked again without shifting to a positioning area such as outdoors, it will be the last recorded point. Since the position information of the entrance of the parking lot is stored as the final positioning position, it is possible to determine whether it is a cancellation area and execute the operation of monitoring / not parking with the content desired by the user set in the drive recorder. it can.

Further, in this embodiment, a plurality of registration points (parking position information) of the cancellation area (for example, 200 cases) can be registered. Each parking position information registered in the position information storage unit 35 has a function of associating and registering the number of times referred to in the subsequent use. That is, the number of times the car has been parked since then is associated with the registered cancellation area and registered. When the number of cancellation areas registered in the location information storage unit 35 is the maximum value that can be registered (for example, 200) and a new cancellation area is registered, the most registered cancellation area has the least number of references. Deletes the old one and registers it. If there are multiple items with the same number of references and registration date under this condition, the one with the smaller area number is deleted.

To cancel the cancellation area, for example, as shown in FIG. 6A, when the current position Y1 of the vehicle exists in the cancellation area within the radius r centered on the predetermined parking position information X1, the cancellation area is specified. This is performed by deleting the parking position information X1 from the position information storage unit 35. That is, when the center position (parking position information) of the area within the distance r from the current position Y1 exists, the parking position information X1 is deleted.

Further, as described above, additional registration within the cancellation area is not allowed, but if it is outside the cancellation area, it is registered as a new cancellation area even if the current position is near the area. As a result, for example, as shown in FIG. 6B, there is an area where the cancellation areas based on the parking position information X2 and X3, which are the respective registration points, overlap. In such a case, if the vehicle is parked at any position in both areas, it operates regardless of the area of only one of the cancellation areas and the overlapping common area, and the parking monitoring is not performed.

Then, for example, as shown in FIG. 6B as described above, when the current position Y2 of the vehicle exists in the cancellation area within the radius r centered on the different parking position information X2 and X3, the plurality of them. When the cancellation of the cancellation area is instructed while the vehicle is parked in the overlapping area of the cancellation areas, the parking position information X2 and X3 that specify each cancellation area are deleted from the position information storage unit 35. That is, all the cancel areas including the center point of the cancel area within the radius r from the current position are deleted.

(Functions such as temporary parking monitoring and recording in the cancellation area)
In this embodiment, even if the vehicle is parked in the cancellation area based on the parking position information being set, if a predetermined condition is satisfied, the parking monitoring function is provided without changing the setting of the cancellation area. This temporary activation of the parking monitoring mode is executed based on a push operation of a predetermined button portion, which is an operation means performed within a predetermined period after the engine is turned off (ACCOFF), as in the case of setting / canceling the cancel area. Good.

For example, as described above, when the vehicle is stopped at a place in the cancel area and the engine is turned off, the LED 36, which is a power lamp, is turned on in orange, and the sound output unit 33 makes a beeping sound. It is output (see FIG. 5 (b-1)). If only the first button unit 37 is operated within a predetermined time (for example, 10 seconds) after outputting this sound, the first control unit 31 sets the parking monitoring mode without canceling the cancel area at the current position. It is activated and outputs a sound of "pee-piro-piro-piro" from the sound output unit 33. In this way, the cancellation area set in the parking position is not canceled and remains registered. Therefore, when the parking monitoring of this time is completed and the parking is performed again after that, the cancellation area is set to the set cancellation area. Parking is not monitored based on this. Therefore, the parking monitoring only this time can be performed by a one-touch operation on the first button unit 37.

Cancellation areas are, for example, parking lots on company premises, places with other security such as garages with doors and shutters at home, places such as convenience stores where you can return immediately without parking for a long time, coffee shops, etc.・ If you set a place where you can visually check and monitor the parked vehicle from your place of stay, a place where there is an extremely low risk of intrusion or theft from the outside, or a place where parking recording is meaningless, etc. Good. By setting the cancel area, it is possible to suppress the waste of the storage capacity of the memory card and the consumption of the battery.

On the other hand, even in the place where the cancellation area is set, if there is a reason or circumstance that you want to record only this time, it is necessary to cancel the setting of the cancellation area in advance (delete the parking position information) and then park. As described above, in this embodiment, it can be released by pressing the first button portion 37 and the second button portion 38 at the same time when getting off, so that the function setting, mode setting, etc. are performed during the operation of the drive recorder as in the conventional system. Although the complexity can be eliminated compared to using the above, it is complicated because the cancellation area must be reset again at the next parking in order not to record the parking at the next parking. Furthermore, if such resetting is not performed, parking will be recorded and meaningless recording processing will be performed.

In this embodiment, only when you want to monitor parking, you can press the first button 37 to temporarily cancel the cancel function, set the temporary monitoring area and record parking, and the setting of the cancel area is not canceled. Since it is the same as it is, the next time you park, even if you get off without any special operation, the parking will not be recorded reliably. In this way, it is possible to perform the same operation without canceling and resetting the registration of the cancel area, and it is sufficient that the resetting is not forgotten. Therefore, after the engine is turned off, the driver, who is a user, can perform appropriate parking monitoring (including not doing so) according to the parking position even if the driver gets off the vehicle as it is or with a simple operation.

Further, this embodiment has a function of registering a temporary cancellation area outside the cancellation area, which does not record parking only this time. The registration of the temporary cancel area may be performed based on a push operation of a predetermined button portion, which is an operation means performed within a predetermined period after the engine is turned off (ACCOFF), as in the case of setting / canceling the cancel area.

For example, as described above, when the vehicle is stopped in a place other than the cancellation area and the engine is turned off, the LED 36, which is a power lamp, is turned on in red, and the sound output unit 33 outputs a "piro-piro-piro" sound (FIG. 5 (a-1)) Therefore, if only the second button unit 38 is pressed within a predetermined time (for example, 10 seconds) after outputting this sound, the first control unit 31 specifies the current position. The parking position information is registered as a temporary cancellation area without being registered in the parking position storage area of the position information storage unit 35. After registration, the sound output unit 33 outputs a beeping sound, and the LED 36 blinks in orange. If the first button unit 37 is pressed again while the "pip-pip-pip-pip ..." sound is being output, the first control unit 31 releases the temporary cancel area. If you register in the temporary cancellation area, parking monitoring will not be performed during this parking, but this parking position information will not be registered in the location information storage unit 35, so the next time you park in the same location, the engine will be turned off. Even if you get off as it is, parking recording will be done.

As described above, in the present embodiment, the cancellation area is registered / canceled by pressing the first button portion 37 and the second button portion 38 at the same time, and the temporary one (temporary parking monitoring / temporary cancellation area) is the first. This is done by pressing one button portion 37 or the second button portion 38. In this way, various settings and specifications can be made by simply pressing the desired button within a predetermined time after stopping the engine, and the last pressed button operation becomes effective and the button operation for confirmation. Since such as is unnecessary, the user can get off as it is after pressing the desired button portion. Further, the first button portion 37 and the second button portion 38 are arranged close to each other, and there is a risk of performing an unintended operation such as pressing an erroneous button portion or pressing both button portions at the same time, for example, when one is intended to be pressed. Even if there is, in this mode, if there is a button operation, the waiting time for confirming the content will be restarted, so if you find an error from the LED emission color or sound, you will have to do it again within the specified time. The correct button operation is sufficient, and no separate cancellation operation is required.

In this way, the temporary parking monitoring mode is such that when parking in the cancellation area, for example, children are likely to play around and be mischievous, or the parking is likely to be parked for a relatively long time. It is recommended to use it when the situation inside is expected to be different from usual. In addition, when registering a temporary cancellation area, for example, a cancellation area is not normally set, but for example, when there are many people around, parking recording may be performed frequently by detecting people around the area. May be expected. If you get off the train as it is in such a case, there will be a lot of useless recordings that have nothing to do with it. Therefore, it is advisable to register a temporary cancellation area to suppress memory consumption and battery capacity reduction. Also, due to the state of the vehicle battery and internal battery, it is advisable not to record parking only this time. Since these events are temporary due to the parking this time, at the time of the next parking, the user such as the driver can get off without pressing a button to enter the normal registered cancellation area. It is good because the processing based on it is performed.

In addition, for example, when parking a vehicle and getting off the vehicle, the driver does not want to switch the troublesome setting, and even if the driver temporarily parks in a place where parking recording is not normally required, it is troublesome after that. There is a problem that parking recording is surely not performed without performing an operation or the like, but in the present embodiment, such a problem can be solved, which is good.

FIG. 7 shows a processing flow executed in association with ACC OFF when the engine is turned OFF described above. This flowchart is for the case where "ACC OFF interlocking" that automatically shifts to parking monitoring when ACC is turned off is set. Further, in the flowchart shown in FIG. 7, the first control unit 31 and the second control unit 32 operate in cooperation with each other. The first control unit 31 and the second control unit 32 may be collectively referred to as a "control unit".

With the ACC OFF, the control unit determines whether or not the current position is in the cancel area and confirms the ACC state (S1). The ACC status is confirmed by the first control unit 31, and when ACCON is reached, the power supply of the drive recorder 2 is activated. Further, the control during parking after ACCOFF is mainly controlled by the first control unit 31, and the actual determination of whether or not the vehicle is in the cancel area is performed by accessing the position information storage unit 35 and updating the final positioning position. (Ii) The control unit 32 performs the operation.

Therefore, in the determination process of S1, for example, the first control unit 31 inquires the second control unit 32 whether or not the current position is within the cancel area, and the second control unit 32 first determines the determination result. This is done by notifying the control unit 31. Alternatively, as shown in FIGS. 8 to 10, the first control unit 31 confirms the state of the ACC, and if it determines that the ACC is OFF, the second control unit 32 is notified that the ACC is OFF. Then, when the second control unit 32 receives the "ACCOFF" notification, it accesses the position information storage unit 35, acquires the stored final positioning position, and the acquired final positioning position is in the cancel area. Judge whether or not. To determine whether or not it is within the cancellation area, for example, the distance between the final positioning position and the center points (parking position information) of all the stored cancellation areas is obtained, and the distance is within the radius r for specifying the cancellation area. It is better to judge by whether or not there is. All parking position information that specifies the cancellation area stored in the position information storage unit 35 is, for example, read and stored in advance by the second control unit 32 at the time of ACCON when the engine is started, and the stored information and final positioning are stored. If the position is compared with the position, the determination process can be performed quickly.

If the current parking position is not the cancel area, that is, the monitoring area, the process proceeds to process step S2, the control unit blinks the LED 36 in red, and the sound output unit 33 repeatedly outputs a “piro-piro” sound three times. The notification using the LED 36 and / or the sound output unit 33 may be performed by the second control unit 32 that has determined the area, or may be performed by the first control unit 31 that has received the determination result from the second control unit 32. Good.

Next, the control unit notifies the current situation (not the cancel area) and waits for a predetermined time (for example, 10 seconds) to elapse. Then, during the standby, the first control unit 31 confirms the switch operation for the first button unit 37 and the second button unit 38 and the state of the ACC (S3). If the ACC is turned on during standby, the power of the drive recorder 2 is activated. When the time-out occurs after the lapse of a predetermined time, the control unit turns off the LED 36 (S15) and shifts to the parking monitoring mode (see FIG. 8A).

When the second button unit 38 (SW2) is pressed independently during the standby of S3, the control unit sets the temporary cancel area, blinks the LED in a predetermined color, and makes the sound output unit 33 "pip pip pip pip". The sound "..." is continuously output (S5). This process may be performed by, for example, the first control unit 31, or when the second control unit controls the LED 36 and the sound output unit 33, the first control unit 31 controls the second control unit 32. The first button unit 37 is notified that it has been pressed, and the second control unit 32 that receives the notification performs a predetermined process. Since it is a temporary cancellation area, it will not be registered in the location information storage unit 35.

After that, the process proceeds to process step S6, and the first control unit 31 waits for a predetermined time (for example, 10 seconds) to elapse. Then, during the standby, the first control unit 31 confirms the switch operation and the ACC state (S6). Then, when ACCON is performed, the drive recorder 2 is activated, and when the first button unit 37 (SW1) is pressed independently, the control unit proceeds to the processing step S7, sets the monitoring area, and sets the LED. In addition to blinking in the color of, the sound output unit 33 outputs a "piro-piro" sound three times (S7). After that, the process returns to the process step S3, and the above-described process is performed. Then, when a time-out occurs without processing during S6 standby, the control unit turns off the LED 36 (S8) and shifts to the parking monitoring prohibition mode. When the parking monitoring prohibition mode is entered, both the first control unit 31 and the second control unit 32 are turned off, and the power supply to the drive recorder 2 is stopped.

On the other hand, when the first button unit 37 and the second button unit 38 are pressed at the same time during the standby of S3 (SW1 + SW2), the first control unit 31 informs the second control unit that both of the buttons are pressed. Notify (see FIG. 9). Then, the second control unit 32 that receives the notification registers the current position, that is, the final positioning position, in the position information storage unit 35 as the parking position information of the cancel area. Then, the control unit blinks the LED in a predetermined color, and continuously outputs the sound "pip-pip-pip-pip ..." from the sound output unit 33 (S4). By executing this processing step S4, the current position is registered in the cancel area and the parking position is in the cancel area. Therefore, the process proceeds to process step S10, and the process shifts to the processing system in the cancel area.

Further, when it is determined in S1 that the current position is within the cancel area, the control unit blinks the LED in a predetermined color and continuously outputs the sound "Pip Pip Pip Pip ..." from the sound output unit 33. (S9). Next, after notifying the current situation (in the cancellation area) in S9, it waits for a predetermined time (for example, 10 seconds) to elapse. Then, during the standby, the first control unit 31 confirms the switch operation for the first button unit 37 and the second button unit 38 and the state of the ACC (S10). If the ACC is turned on during standby, the power of the drive recorder 2 is activated. When the time-out occurs after the lapse of a predetermined time, the LED 36 is turned off (S8), and the parking monitoring prohibition mode is entered (see FIG. 8B).

When the first button unit 37 (SW1) is pressed independently during the standby mode of S10, the temporary monitoring area is set, the LED blinks in red, and the sound output unit 33 outputs a "pee-piro-piro-piro" sound ( S12). This process may be performed by, for example, the first control unit 31, or when the second control unit 32 controls the LED 36 and the sound output unit 33, the first control unit 31 controls the second control unit 32. The first button unit 37 is notified that the first button unit 37 has been pressed, and the second control unit 32 that has received the notification performs a predetermined process. Since the cancellation area is temporarily canceled and is a temporary monitoring area, the cancellation process corresponding to the current position registered in the position information storage unit 35, that is, the corresponding parking position information is not deleted.

After that, the process proceeds to process step S13, and the first control unit 31 waits for a predetermined time (for example, 10 seconds) to elapse. Then, during the standby, the first control unit 31 confirms the switch operation and the ACC state (S13). Then, when ACCON is performed, the drive recorder 2 is activated, and when the second button portion 38 (SW2) is pressed independently, the process proceeds to process step S25, the monitoring cancel area is set, and the LED blinks in red. At the same time, the sound output unit 33 outputs a “piro-piro” sound three times (S14). After that, the process returns to the process step S10, and the above-described process is performed. Then, when the process is not performed during the standby of S13 and a time-out occurs, the LED 36 is turned off (S15), and the parking monitoring mode is entered.

On the other hand, when the first button unit 37 and the second button unit 38 are pressed at the same time during the standby of S10 (SW1 + SW2), the first control unit 31 indicates that both of the buttons have been pressed by the second control unit 32. (See FIG. 10). Then, the second control unit 32 that receives the notification deletes the parking position information of the cancel area corresponding to the current position from the position information storage unit 35, and releases the cancel area. Then, the control unit blinks the LED 36 in red and outputs a “piro-piro” sound from the sound output unit 33 three times (S11). By executing this processing step S11, the cancel area including the current position is released, so that the parking position is outside the cancel area. Therefore, the process proceeds to process step S3, and the parking position is outside the cancel area, that is, in the processing system of the monitoring area. Transition.

FIG. 11 shows an example of a processing flow executed in association with the above-mentioned engine OFF / ACC OFF. This flowchart is for the case where a "manual" to be migrated based on a manual operation is set. When the manual is set, parking monitoring is performed when the first button portion 37 is pushed, and parking monitoring is not performed when there is no push operation between the time when the ACC is turned off and the predetermined time elapses. To. In this way, the parking monitoring in the manual mode of this embodiment is performed when there is some action from the user, and the parking monitoring is not performed when the vehicle gets off without any operation.

Along with the ACC OFF, the control unit blinks the LED 36 in a predetermined color and continuously outputs a beeping sound from the sound output unit 33 (S21). Next, the control unit waits for a predetermined time (for example, 10 seconds) to elapse after notifying the current situation (manual). Then, during the standby, the first control unit 31 confirms the switch operation for the first button unit 37 (SW1) and the state of the ACC (S22). If the ACC is turned on during standby, the power of the drive recorder 2 is activated. When the time-out occurs after the lapse of a predetermined time, the LED 36 is turned off (S26), and the parking monitoring prohibition mode is entered. As a result, the first control unit 31 and the second control unit 32 are turned off, and the power supply to the drive recorder is cut off.

Further, when the first button unit 37 (SW1) is pressed independently during the standby of S22, the control unit blinks the LED 36 in red and outputs the sound output unit 33 three times. (S23). When the first button portion 37 is pressed while the manual is set, parking monitoring is performed. After that, the first control unit 31 waits for a predetermined time (for example, 10 seconds) to elapse. Then, during the standby, the first control unit 31 confirms the switch operation and the ACC state (S24). If a time-out occurs without processing during standby, the parking monitoring mode specified by pushing the first button unit 37 is confirmed. Then, the LED 36 is turned off (S25), and the parking monitoring mode is entered.

On the other hand, when the second button unit 38 (SW2) is pressed independently during the standby of the standby S24, it is an instruction to cancel the push operation of the first button unit 37, returns to S21, and performs each of the above processes. If ACCON is performed during standby, the drive recorder 2 is started.

In each of the above-described modes, after shifting to the parking monitoring mode, the first control unit 31 is always ON to control a predetermined input device / output device or control ON / OFF of the second control unit 32. To do. Then, when the second control unit 32 is turned on, shooting is started and recording is also performed. The first control unit 31 determines whether or not to record. For example, in the case of parking monitoring outside the cancellation area and continuous recording, the first control unit 31 keeps the second control unit 32 ON. On the other hand, in the case of event recording, the second control unit 32 is once turned off and turned on at the time of the event. If it is in the cancel area, the second control unit 32 is turned off. Further, when the second control unit 32 is turned on, it is preferable to record a normal continuous recording or a video with a slowed frame rate.

[Second Embodiment]
FIG. 12 shows an example of a second embodiment of the system. The second embodiment is also an embodiment relating to surveillance recording during parking. In the system of this embodiment, the drive recorder 51 is connected to a vehicle or other equipment via a junction unit 52. The junction unit 52 corresponds to a connection control device. Other devices include, for example, a GPS antenna unit 53, a radar detector 54, a DMS (driver monitoring system) unit 55, and the like. The junction unit 52 includes a main body case having a predetermined shape such as a rectangle, and a connector for connecting to each of the above-mentioned devices is provided on the side surface of the main body case. The connector connects, for example, a first connector 61a for connecting the drive recorder 51, a second connector 61b for connecting the GPS antenna unit 53, a third connector 61c for connecting the radar detector 54, and a DMS unit 55. A fourth connector 61d or the like is provided. Further, the junction unit 52 includes a fifth connector 61e for connecting the OBD adapter cable 56 and a sixth connector 61f for power supply. The sixth connector 61f is optionally fitted with a connection cable 58 connected to the power supply device 57 or a power cable 59 connected to the vehicle battery. The connection cable 58 uses a 4-core power cable, and the power cable 59 uses a 3-core power cord. The radar detector 54 includes a control unit having a CPU and a memory, an interface for connecting to the junction unit 52, various sensors, and the like. Each part of the radar detector 54 is controlled by a control unit. The radar detector 54 has an alarm function of detecting a predetermined radar and issuing an alarm. The radar detector 54 may further have a function of detecting a predetermined laser beam and issuing an alarm. The radar detector 54 also functions as an information display terminal that displays a screen related to the parking monitoring function, as will be described later. The radar detector 54 includes a touch panel on which a touch sensor is superimposed on a display as a means for receiving an operation on the screen. The radar detector 54 turns off the screen during recording by the parking monitoring function. The radar detector 54 corresponds to the second device.

As the power supply device 57, for example, the same power supply device 3 as in the above-described embodiment may be used. The power supply device 57 has a rechargeable internal battery, is connected to the vehicle battery using a cable (not shown), receives power from the vehicle battery at ACCON to charge the internal battery, and charges the internal battery at ACCOFF. It is preferable to discharge the internal battery to supply power to the junction unit 52 and thus to each device connected to the junction unit 52. Further, in the ACCON state, the power supply device 57 also supplies electric power to the junction unit 52 while charging the internal battery.

The junction unit 52 includes a power supply IC 62, a communication control unit 63, and a power supply control unit 64 in the main body case. The power supply IC 62 has a function of supplying power to each device connected to the junction unit 52 based on the power supplied from the power supply. The power supply IC 62 connects its input unit to terminals such as the power supply line of the sixth connector 61f, and connects the output unit to terminals such as the power supply line of the first connector 61a to the fourth connector 61d, the communication control unit 63, and the power supply control unit. It is connected to the power supply voltage terminal portion of 64, and a predetermined voltage value (for example, 5V) is supplied to each of the input voltage supplied from the outside via the sixth connector 61f. The power supply control unit 64 has a power supply control function that controls ON / OFF of the power supply to each device connected to the junction unit 52. The communication control unit 63 has a communication control function. A part or all of the functions of the power supply IC 62, the communication control unit 63, and the power supply control unit 64 may be realized by executing the program. When realized by executing a program, in the junction unit 52, an arithmetic processing unit (computer) such as a CPU reads the program and necessary data into a memory such as a RAM, and performs various arithmetic actions according to the program. Each function of the junction unit 52 is realized.

Each device connected to the junction unit 52 sends and receives information and data to and from each other via the communication control unit 63. For example, the drive recorder 51 acquires the current position information from the GPS antenna unit 53. Further, for example, the drive recorder 51 may communicate with the radar detector 54 and use the display unit 65 with a touch panel of the radar detector 54.

The drive recorder 51 includes a front camera unit 66 that is attached to, for example, the windshield of a vehicle to photograph the front of the vehicle, and a rear camera unit 67 that is attached to, for example, the rear glass of the vehicle to photograph the rear of the vehicle. A connection cable 68 for connecting the front camera unit 66 and the rear camera unit 67, a power cable 69 for connecting the front camera unit 66 and the junction unit 52, and the like are provided.

The drive recorder 51 receives power from a predetermined power source via the junction unit 52 via the power cable 69 to the front camera unit 66, and the rear camera unit 67 receives power from the front camera unit via the connection cable 68. Power is supplied via 66. Then, the drive recorder 51 is activated when the ACC is turned on, and records the video captured by the front camera unit 66 and the rear camera unit 67 according to the set operating conditions. The set operating conditions include, for example, a continuous recording mode that constantly records when ACCON is used, an event recording mode that does not constantly record and records when a predetermined event occurs, and a combination thereof. Further, even if the drive recorder is set to the continuous recording mode or the like, the recording may be stopped manually while the vehicle is running or the like. Therefore, when the engine is stopped and the ACC is turned from ON to OFF, a recording state and a non-recording state occur.

Further, although the illustration of the specific internal configuration is omitted, the front camera unit 66 has substantially the same configuration as the block diagram of the embodiment shown in FIG. 1 described above, and for example, the final positioning position is stored in the position information storage unit. Information is recorded, the cancellation area is registered, parking monitoring is not performed when the parking position is the cancellation area, parking monitoring is performed temporarily even within the cancellation area, or the parking position is canceled. It has various functions related to parking monitoring, such as temporarily not recording parking even outside the area. The drive recorder 51 corresponds to the first device.

FIG. 13 is a diagram showing a parking recording start flow that starts when ACC, which is one of the functions of the drive recorder of the present embodiment, is turned from ON to OFF. The drive recorder 51, for example, the control unit mounted on the front camera unit 66 confirms whether or not recording is in progress when the ACC OFF is turned off (S31). When recording is not performed (No in S31), the control unit does not shift to the parking monitoring mode and turns off the power of the drive recorder 51 and the radar detector 54 (S32). In the power off process of the radar detector 54, for example, the control unit sends an instruction to turn off the power to the radar detector 54, and the control unit of the radar detector 54 that receives the instruction shuts down the power. It is good to do. As described above, in this embodiment, parking monitoring is not performed when the engine is not always recorded when the engine is turned off (ACCOFF).

On the other hand, if the recording is always performed when the engine is turned off (ACCOFF) (Yes in S31), the control unit confirms whether or not the parking monitoring mode is set (S33). When the current setting is "No parking monitoring recording" (No in S33), the control unit does not shift to the parking monitoring mode and turns off the power of the drive recorder 51 and the radar detector 54 (S34).

When the setting is "parking monitoring recording" (Yes in S33), the control unit accesses the position information storage unit 35 of the front camera unit 66 and confirms whether or not there is a final positioning position (S35). ).

If there is no final positioning position in the position information storage unit (NO in S35), parking monitoring is started (S36). The state in which the final positioning position is not recorded is, for example, a state in which GPS has never been positioned since the system was started. For example, it is the first time for a vehicle parked or stopped in a place where GPS cannot be positioned, such as an underground parking lot. This is the case when a drive recorder is attached, the power is turned on, and the ACC is turned off without positioning. In such a case, it is unknown whether it is a cancellation area, so we decided to monitor parking. With the start of this parking monitoring, the power of the radar detector 54 is turned off, and the power of the drive recorder 51 is kept on and continued (S37).

If there is a final positioning position (Yes in S35), the control unit determines whether or not the current position (final positioning position) is within the cancel area (S38). This determination is the same as in the above-described embodiment. If GPS cannot be positioned even once after the drive recorder is started and the final positioning position is not recorded in the position information storage unit of the drive recorder 51 and the front camera unit 66, for example, the non-volatile memory of the radar detector 54. If there is a final positioning position saved in, use it. By doing so, even if the final positioning position is not recorded in the drive recorder 51, it may be possible to determine whether or not it is within the cancel area based on the final positioning position held by the radar detector 54. When using the final positioning position stored in the radar detector 54 side, the control unit of the front camera unit 66 accesses its own position information storage unit and if the final positioning position is not recorded, the junction unit It is preferable that the radar detector 54 is inquired about the final positioning position information via the communication control unit 63 of the 52, and is acquired by the response from the radar detector 54.

Then, when the final positioning position is not in the cancel area but outside the cancel area (NO in S38), the control unit starts by setting the timer to 10 seconds and displays "parking" on the display unit 65 of the radar detector 54. The "monitoring screen" is displayed, and the parking monitoring mode is waited for (S39).

As shown in FIGS. 14A and 15A, this parking monitoring screen displays the title item 71a of "parking monitoring" at the left end of the area above the parking monitoring screen, and displays the camera mark 71b at the right end. .. This allows the user to easily understand from the text and image that the parking monitoring mode is currently selected. FIG. 15A shows an example of a screen displayed on the actual display unit 65.

Further, the battery voltage display unit 71c is arranged in the center of the upper region of the parking monitoring screen. The battery voltage display unit 71c is an area for displaying the battery voltage, which is the voltage value of the vehicle battery. The power cable 59 is connected to the sixth connector 61f to directly supply power to the junction unit 52 from the vehicle battery. If so, the battery voltage is acquired and displayed. Then, when the power supply device 57 is connected, the battery voltage is not displayed. When the battery voltage is not displayed, the message "inside the cancel area" is displayed as information instead of the voltage value, so that the screen area of the display unit can be effectively used. Whether the power supply device 57 or the vehicle battery is connected can be determined by, for example, whether or not communication is possible because the power supply device 57 has a communication function. For example, to the sixth connector 61f. Judging from the voltage value of the input voltage supplied from the outside, it may be easily determined.

The power supply control unit 64 has a wiring that is directly connected to the sixth connector 61f, in addition to the power supply line that receives the power supply voltage from the power supply IC 62. The power supply control unit 64 has a function of detecting the voltage value of the input voltage supplied from the outside through the sixth connector 61f via the wiring thereof. Therefore, when the vehicle battery is directly connected to the sixth connector 61f, for example, the power supply control unit 64 detects the vehicle battery voltage by the function of detecting the voltage value of the input voltage. The battery voltage display unit 71c may display the voltage value acquired by the detection function. On the other hand, for example, when the power supply device 57 is connected to the sixth connector 61f, the input voltage from the power supply device 57, that is, the voltage value of the internal battery of the power supply device 57 is detected by the function of detecting the voltage value. The vehicle battery voltage cannot be detected directly. Therefore, displaying the detected voltage value is not the battery voltage of the vehicle and is meaningless. Therefore, when the power supply device 57 is connected, the battery voltage display unit 71c is hidden.

When connected to the vehicle battery, the battery voltage value is displayed, so the user should check the battery charge status, etc., and judge whether it is okay to monitor parking during this parking. It is possible to make appropriate settings for the presence or absence of parking monitoring. The battery voltage display unit 71c serves as an index for stopping parking monitoring when the battery of the vehicle is slightly worn out, and serves as an index for the user to make a judgment.

Further, the drive recorder 51 and the front camera unit 66 may be provided with a function of not starting when the battery voltage becomes lower than the threshold value during parking monitoring, and the threshold value of not starting may be changed by setting. .. The battery voltage of the vehicle may be constantly low / high depending on the vehicle, and the threshold value cannot be uniformly determined. Therefore, the threshold value must be set appropriately and is normally displayed on the battery voltage display unit 71c. By confirming the battery voltage, the threshold value can be set appropriately.

Further, by changing the display mode depending on the power supply connected to the sixth connector 61f, by looking at the display mode in the area of the battery voltage display unit 71c, it is connected to the battery of the vehicle or to the power supply device 57. It's good because you can see if it's done.

Further, in the upper area of the parking monitoring screen, the remaining time indicator 71d is arranged on the upper side. The remaining time indicator 71d displays the remaining time of the timer set for 10 seconds and started, and the bar becomes shorter with the passage of time, and when 10 seconds have passed, the bar reaches the right end. A user such as a driver can know the remaining time until the mode is confirmed by looking at the remaining time indicator 71d.

Further, on the parking monitoring screen, the wide area below the remaining time indicator 71d is divided into two left and right, the cancel area setting button area 71e which is the first area is arranged on the left side, and the temporary area which is the second area is arranged on the right side. The cancel button area 71f is arranged. In each button area, an image showing the contents and characters are displayed in large size so that the contents assigned to each button area can be intuitively understood. By providing each button area in many areas of the display unit 65, it is possible to suppress the occurrence of erroneous touches such as erroneous pressing and erroneous pressing at the same time.

As described above, the control unit displays the parking monitoring screen, changes the display of the bar of the remaining time indicator 71d with the passage of time, and starts parking monitoring when a timeout has elapsed after 10 seconds (S40). Then, with the start of this parking monitoring, the power of the radar detector 54 is turned off, and the power of the drive recorder 51 is kept on and continued (S41).

When the temporary cancel button area 71f on the right side is touched while the "parking monitoring screen" is displayed, the control unit does not shift to the parking monitoring mode as the temporary parking monitoring cancellation only this time, and the drive recorder 51 and the radar detector 54 do not shift to the parking monitoring mode. Turn off the power of (S42). At this time, since the cancellation area is not registered based on the current position, for example, when parking at the same place next time, the control unit displays the parking monitoring screen and stands by in the parking monitoring mode. In the above-described embodiment, the timer is restarted by the button operation, but in the present embodiment, the timer is determined immediately without waiting for 10 seconds. This is because both button parts are displayed side by side on the display part in large size, so there is no mistake in pressing the button, so the state changes immediately and you can get off immediately.

Further, when the parking monitoring screen is displayed in S39 and the cancel area setting button area 71e is touched while waiting until the time-out occurs, the radar detector 54 notifies the drive recorder to that effect, and the front camera unit 66. The control unit sets and registers the current position in the cancel area according to the notification. After that, the control unit displays a "power OFF screen" on the display unit 65 of the radar detector 54, and restarts the standby time of 10 seconds (S43).

On the power off screen, as shown in FIGS. 14 (b), 15 (b), etc., the title item 72a of "power off" is displayed at the left end of the area above the power off screen, and the mark 72b imitating the power button is displayed at the right end. Is displayed. Further, in the center of the upper area of the power OFF screen, a layout is adopted in which the characters 72c "inside the cancel area" are displayed. This makes it easy for the user to understand from the text and image that they are currently in the cancel area. FIG. 15B shows an example of a screen displayed on the actual display unit 65. Further, in the upper region of the power OFF screen, the remaining time indicator 72d is arranged on the upper side. The remaining time indicator 72d displays the remaining time of the timer set for 10 seconds and started, and the bar becomes shorter with the passage of time, and when 10 seconds have passed, the bar reaches the right end. A user such as a driver can know the remaining time until the mode is confirmed by looking at the remaining time indicator 72d.

Further, on the power OFF screen, the wide area below the remaining time indicator 72d is divided into two left and right, the cancel area release button area 72e which is the first area is arranged on the left side, and the temporary area which is the second area is arranged on the right side. The parking monitoring button portion 72f is arranged. In each button area, an image showing the contents and characters are displayed in large size so that the contents assigned to each button area can be intuitively understood. By providing each button area in many areas of the display unit 65, it is possible to suppress the occurrence of erroneous touches such as erroneous pressing and erroneous pressing at the same time.

As described above, the control unit displays the power OFF screen, changes the display of the bar of the remaining time indicator 72d with the passage of time, and performs parking monitoring because it is in the cancellation area when the time-out occurs after 10 seconds have passed. Absent. Then, with the stop of the parking monitoring, the power of the radar detector 54 and the drive recorder 51 is turned off (S44).

When the temporary parking monitoring button 72f on the right side is pressed while the "power OFF screen" is displayed, the parking monitoring mode is set only this time, and the parking monitoring is started (S45). Then, with the start of this parking monitoring, the power of the radar detector 54 is turned off, and the power of the drive recorder 51 is kept on and continued (S46). Even in this example, the decision is made immediately without waiting for 10 seconds. Since there is no mistake in pressing the button, it is possible to get off immediately by changing the state immediately.

On the other hand, when the cancel area release button area 72e on the left side of the "power OFF screen" is pressed, the cancel area corresponding to the current position is released, the "parking monitoring screen" is displayed, and the waiting time of 10 seconds is restarted.

If the current position is in the cancel area, Yes in S38 and the "power off screen" is displayed (S43). Then, the same processing as described above is performed thereafter.

As described above, also in the present embodiment, "cancellation area setting" and "cancellation area cancellation" are updated by pressing a button, and the screens are alternately changed (10-second restart). ..

As described above, in the present embodiment, the "parking monitoring screen" has a function of displaying the battery voltage. As a result, the user can look at the battery voltage and temporarily cancel it if the battery is about to run out, or weigh the battery voltage and the parking situation on both balances to make a comprehensive judgment and take the appropriate usage mode. it can. On the other hand, the battery voltage is not displayed on the power off screen. Since the parking center is not monitored in the cancellation area, there is little need to notify the battery voltage, and by notifying the user that the parking area is the "cancellation area" using the area displaying the battery voltage display unit 71c, this parking position is notified to the user. Then, we made it aware that parking is not monitored as it is registered in the cancellation area, and we tried to give an opportunity to cancel the cancellation area and perform temporary parking monitoring as needed.

In this embodiment, as shown in FIGS. 12, 14 to 16, etc., the operation screen is displayed on the display unit 65 of the radar detector 54, and it is easy to set cancellation / temporary cancellation and register / cancel the cancellation area. did. Like the drive recorder 2 shown in FIGS. 1 to 4, a single device having a button portion in the main body case of the drive recorder does not have a display unit, or even if it has a display unit, it is small, so that the screen can be touched. Difficult to use as an input unit. On the other hand, in the present embodiment, since a device different from the drive recorder is used, if a device having a large display unit is used or a device installed near the driver such as a dashboard is used, the display content is displayed. It is easy to see and a large area can be secured as the area of the button part, so operability is good.

Basically, get off as it is. That is, for example, by looking at the screen of the radar detector, it is confirmed whether it is as desired, and if it is okay, if it gets off as it is, it will operate after 10 seconds, for example. In addition, it is possible to give a predetermined instruction with one touch of the screen. You can also register / delete the cancellation area with one touch. Since the current status (cancellation area set / not set) can be known, it is possible to know whether the current setting status is correct or not, and then the correct operation (getting off without operation) is possible. Normally, the mode setting screen is started, but it can be done easily with one touch.

[Function of power supply control unit]
The power supply control unit 64 controls ON / OFF of the power supply in the connected device and the junction unit 52. FIG. 17 shows the power control state transition for the radar detector (RD). The power supply 57 is referred to as "OP power supply", and the radar detector is referred to as RD. Further, T1 is a power OFF guard timer, which is a guard value when the power device 57 does not turn off. For example, it may be about 15 seconds. T2 is a timer waiting for the end of the radar detector, and may be set to, for example, about 10 seconds.

The power control unit 64 turns on the radar detector at ACCON. Then, after ACC OFF, the power state of the power supply device is referred to, and if the OP power is ON, wait until the OP power is OFF. If the OP power is off, it waits for the RD power off permission, and when it is permitted, it transitions to the power off state. The RD power OFF permission is determined based on the drive recorder (DVR) power state. Wait for the parking monitoring cancellation / temporary cancellation and the cancellation area setting / cancellation operation (with a 10-second extension), and turn it off when finished. Since each screen is displayed on the display unit 65 of the radar detector 54, power is continuously supplied to the radar detector 54 so as not to drop it.

FIG. 18 shows the power supply control state transition for the drive recorder (DVR). In the figure, T1 is a parking recording determination inquiry response reception timer, and may be set to, for example, about 500 [ms]. T2 is a parking recording determination result waiting timer, which is a time for inquiring the RD whether or not to monitor parking. For example, it may be about 15 seconds. T3 is a parking recording timer, which is a set value stored in DATA FLASH in the junction unit 52. This setting value may be changed, for example, in the setting menu of the radar detector.

This power supply control state diagram is a control for the drive recorder that executes the flowchart shown in FIG. If the ACC is turned off and the parking monitoring is turned off, the power is turned off immediately, and if the judgment is in progress, the power is turned on continuously.

In the figure, in the block of "parking recording cancellation determination", the parking monitoring screen / power off screen is displayed on the display unit of the radar detector, and the state is waiting for an instruction from the radar detector. Then, when the instruction and response from the radar detector do not record parking, the power is turned off at an appropriate timing.

To give a specific example, the DVR power is turned on when the ACC is ON, and the DVR power is turned off when the parking recording setting is OFF when the ACC is OFF. On the other hand, if the parking recording setting is ON when the ACC is OFF, the radar detector is inquired whether to cancel the parking recording. Based on the result of the parking recording inquiry from the radar detector, the drive recorder (DVR) is instructed to perform parking recording when parking recording is performed, and the DVR power is turned off when parking recording is not performed.

In the block of "parking recording determination transmission", T1 is set and retried when communication is not possible, and when communication is still not possible and the time is up, the power is continuously turned on to start recording. Further, in the block of "waiting for parking recording determination result", every time the cancel area setting button area 71e or the cancel area release button area 72e on the left side of the screen of the display unit 65 is touched, the radar detector issues an extension instruction of 10 seconds. Set the sent (Timer Extend) and T2 (parking recording judgment result waiting timer) and restart.

Further, when parking recording is performed, the DVR power is turned off when the parking recording time ends or the voltage drops, as shown in the "parking recording in progress" block. Further, when a function capable of changing and setting the frame rate during parking recording is provided, for example, a 1 fps setting and a normal setting (for example, 30 fps) may be selectable. By making the parking recording slower than the normal setting, for example, 1 fps, the power consumption of the battery can be suppressed and the recording for a long time becomes possible. Then, when the function is provided, the parking recording start and stop may be sent to the DVR only in the case of the 1 fps setting. During parking recording, the DVR is requested to notify the status periodically (for example, every 3 seconds). If an abnormality (recording stopped, no SD card, etc.) is detected, the power is turned off. Further, the power is continuously supplied during recording, but when the set time (T3: maximum 9 hours) elapses, the power is turned off.

In the present embodiment, since the radar detector 54 and the junction unit 52 are separate units, such power supply control is required, and the junction unit 52 determines and controls the power supply state while communicating with the radar detector. To do.

FIG. 19 shows a power supply control state transition for the junction unit (JCT) 52. In the figure, the control for oneself is turned off when the power of all connected devices is turned off.

For example, when the ACC is turned on, the power is turned on and the power is self-held. In this power supply self-holding, for example, the ACC is connected to one of the two inputs OR, and the self-output is input to the other input. Therefore, when the JCT is turned on as the ACC is turned on, it continues to be turned on even if the ACC is turned off. During ACC OFF, after confirming that all other power supplies have been turned off, turn off the JCT power supply and remove the power supply self-holding. Also, after removing the self-holding, if the ACC is turned on again while the power supply voltage is dropping, the MPU of the JCT is restarted.

20 and 21 show an example of a setting screen and the like for setting the system. This setting screen or the like is displayed on the display unit 65 of the radar detector 54 while the junction unit 52 and the radar detector 54 communicate with each other, and the junction unit 52 switches the screen based on the touched position on the screen. Performs processing such as instructing and updating the settings for the corresponding device. FIG. 20A shows an example of an “external device setting menu screen” that is displayed by transitioning from the top screen of the setting (not shown) with the touch of the screen. In this menu screen, the title display unit 80a is arranged at the upper end, and a predetermined number of setting item display areas 80b are arranged vertically by using many areas below the title display unit 80a, and the right end. The cursor buttons 80c are arranged above and below, the page display unit 80d is arranged in the center of the right end, and the back button 80e and the top button 80f are arranged below the left end. The title display unit 80a displays "external device setting" indicating that the screen is an external device setting screen.

When the back button 80e is touched, the control unit of the junction unit performs a process of returning the screen display to the next higher screen. When the top button 80f is touched, the control unit switches to the display of the top screen, for example, the standby screen.

The setting item display area 80b is formed horizontally, and the title of the setting item is displayed on the left end side thereof. Further, for example, as shown in FIGS. 20 (c) to 20 (e), the current setting contents are displayed on the right end side of the setting item display area 80b.

The page display unit 80d indicates how many pages the screen is composed of. In this embodiment, four setting item display areas 80b are displayed on one page. If there are 5 or more items on the setting screen, they are divided into multiple pages and displayed. The page display unit 80d displays the total number of pages and the number of pages of the screen currently being displayed. For example, in the example of FIG. 20A, since there are four items of the external device to be set, the page display unit 80d displays "1/1" because it is composed of one page. Further, for example, in the example of FIG. 20C, the drive recorder setting screen has three pages in total, and since it is the first page thereof, "1/3" is displayed on the page display unit 80d. The cursor button 80c is a button for switching to each screen when the setting screen is composed of a plurality of screens as described above. For example, since FIG. 20 (c) shows the screen of the first page, when the downward cursor button 80c is touched, the screen of the second page is displayed as shown in FIG. 20 (d).

When setting the parking monitoring in the drive legoda, touch the top setting item display area 80b (DR) on the menu screen shown in FIG. 20 (a). When the control unit detects such a touch, the control unit switches to the display of the drive recorder setting screen shown in FIG. 20 (c). Also, if recording is currently in progress, "stop recording" is performed to make settings. At this time, before switching the screen from FIG. 20 (a) to FIG. 20 (c), a notification screen for notifying "recording stop" is displayed as shown in FIG. 20 (b). Then, when the recording is stopped, the current setting value is acquired from the drive recorder 51, and the first page of the drive recorder setting screen is displayed (see FIG. 20C).

On this drive recorder setting screen, "DR setting" is displayed on the title display unit 80a so that the function setting of the drive recorder can be understood. Further, in each setting item display area 80b, the title of the setting item is displayed on the left end side, and the acquired current setting content is displayed on the right end side. By touching the cursor button 80c, transitions between FIGS. 20 (c), (d), and (e) are performed. Then, when it is detected that the fourth "parking monitoring" setting item display area 80b is touched on the setting screen on the second page shown in FIG. 20 (d), the control unit of the junction unit 52 displays FIG. 20 (d). The parking monitoring setting screen shown in f) is displayed.

The initial value of "parking monitoring recording" in the top setting item display area 80b may be, for example, OFF. Some users who have purchased this type of system use the default values. If the initial value is set to ON and parking monitoring is performed, the battery of the vehicle or the internal battery of the power supply device may be consumed unexpectedly. Furthermore, if you do not notice that parking monitoring is being performed, you will waste memory capacity. Therefore, a user who wants to turn off the initial value and perform parking monitoring can change the setting according to his / her own will and operation to perform subsequent parking monitoring in an appropriate state, manage the battery, and use the parking recorded video. Can be done properly. FIG. 20 (f) shows an example in which parking monitoring recording is selected by setting (“ON” is displayed at the right end of the setting item display area 80b).

When parking monitoring recording is OFF, the following three items cannot be selected, so that screen switching does not occur even if pressed. Further, when changing the parking monitoring time (FIG. 20 (f) shows an example in which 9 hours are set), which is one of the setting items on the parking monitoring setting screen, the user sets the second setting from the top. Touch the item display area 80b. When the touch is detected, the control unit displays the first page of the parking monitoring time setting screen shown in FIG. 20 (g). Upon receiving the touch of the cursor button 80c, the control unit switches the screen between FIGS. 20 (g) and 20 (h), and sets the time allocated to the touched selection item display area as the parking monitoring time. To do. When the set parking monitoring time elapses, the parking recording is stopped and the power is turned off.

Further, when changing the parking monitoring end voltage (FIG. 20 (f) shows an example in which 12.2 V is set), which is one of the setting items on the parking monitoring setting screen, the user can use 3 from the above. Touch the second setting item display area 80b. When the touch is detected, the control unit displays the first page of the parking monitoring end voltage setting screen shown in FIG. 20 (i). Upon receiving the touch of the cursor button 80c, the control unit switches the screen between FIGS. 20 (i) and 20 (j), and uses the voltage assigned to the touched selection item display area as the parking monitoring end voltage. set. When the external battery voltage, for example, the input voltage to the junction unit 52 becomes equal to or lower than the set parking monitoring end voltage, the junction unit 52 stops parking recording and performs a power-off process. In addition, in order to prevent the vehicle battery from running down, it is advisable to assign a high value as the voltage of the selection item so that the end voltage can be set high.

The item "parking monitoring end voltage" is invalid only when a predetermined power supply device is connected to the sixth connector 61f of the junction unit 52. This is because the predetermined power supply device is not designed to end when the parking monitoring time elapses or the remaining battery level is exhausted, and the voltage of the battery is set to end the recording.

FIG. 21A shows an example of the system setting screen displayed on the display unit 65. It has a function to erase the cancel area using this system screen. When it is detected that the second setting item display area 80b displayed as the parking monitoring cancel area is touched, the control unit switches the display of the display unit 65 to the confirmation screen shown in FIG. 21B. When the Yes button 80g is touched on this confirmation screen, the specific information (center position) of all the cancel areas registered in the position information storage unit 35 is deleted. When the back button 80h is touched, the screen is switched to the screen one level higher, for example, the screen shown in FIG. 21 (a). In this way, in this embodiment, the cancellation area including the current position can be registered / canceled by placing it in the parking position and touching the screen, but it can also be done by setting, and the registration / cancellation can be performed by an appropriate method. good.

Then, when actually performing parking monitoring, parking monitoring is performed with the contents set on this setting screen. If you want to temporarily cancel parking monitoring inside or outside the cancellation area, it will be turned off without going to see this setting in the first place.

21 (c) and 21 (d) show an example of version information displayed on the display unit in accordance with a predetermined screen operation. The version of the junction unit 52 is displayed on the right side of the "junction" item at the bottom of the screen. In the display of this version information, if there is an "M" at the end of the junction version, it indicates that a predetermined power supply device is connected to the junction unit. This allows you to check this version information, for example, even if the power supply is in a position that is difficult to see from the driver's seat, etc., and you cannot immediately check whether it is connected to the vehicle battery or the power supply. It is good because it is easy to understand.

[Third Embodiment]
In this embodiment, an embodiment of event recording according to the state of the driver of the vehicle will be described. This event recording is provided to fulfill the function of increasing the importance of the recorded data. Among the recorded data of the drive recorder, there is a problem that it is difficult to know where the recorded data during driving in a state where an accident is likely to occur (so-called hiyari hat) is recorded. Since the current drive recorder specializes in recording at the time of an accident, when there is a large impact such that the G sensor exceeds the threshold value, it is saved with increasing importance as an event recording. However, if the user does not instruct the event button recording in a state where an accident is likely to occur (hiyari hat), the image at the time of the hiyari hat is buried in the image of the normal recording, which may be difficult to understand later. Therefore, it is troublesome to look back on the hiyari hat driving with a video. Therefore, the inventor thought that new value could be added by distinguishing and saving the recording with a higher priority than the normal recording during the hiyari hat operation.

The configuration of the system of the present embodiment is premised on the configuration of the system of the second embodiment described above, and the differences will be mainly described below. Vehicles are general four-wheeled passenger cars, medium-sized and larger passenger cars such as buses, and freight cars such as trucks.

The DMS unit 55 includes a control unit having a CPU and a memory, an image processing unit that performs image recognition and the like, an operation unit that accepts user operations, a camera, an interface that connects to the junction unit 52, and the like. Each part of the DMS unit 55 is controlled by the control unit. The DMS unit 55 captures an image of the driver (mainly a face), recognizes the captured image, and determines the state of the driver. As the image recognition algorithm, for example, a known image recognition algorithm may be adopted. The DMS unit 55 detects, for example, the direction of the user's face, the direction of the line of sight, and the opening / closing of the eyelids, and determines the state of the driver. The state of the driver is a state determined in advance as the state of the driver, and in the present embodiment, the driver is dozing or driving aside. The state in which the driver is dozing or looking aside includes not only the case where the driver is actually in such a state but also the case where the DMS unit 55 determines that there is a possibility of such a state. Such a driver's condition is a condition that may induce a danger such as an accident.

When the DMS unit 55 determines that the driver is dozing or driving aside, a predetermined event (hereinafter referred to as "DMS event") is generated and the junction unit 52 is notified. The DMS event may be a signal that can recognize the type of driver's condition (sleeping or aside driving, etc.). The DMS unit 55 is preferably mounted above the windshield above the user's line of sight using a predetermined mounting member, but may be mounted in a rearview mirror, dashboard, or other location. The junction unit 52 (communication control unit 63) outputs a DMS event signal indicating the occurrence of a DMS event to the radar detector 54. When the radar detector 54 receives the DMS event signal, it outputs a DMS event recording signal instructing execution of event recording (hereinafter referred to as "DMS event recording") to the drive recorder 51.

The drive recorder 51 records the DMS event by receiving the DMS event recording signal (that is, the driver is dozing or looking aside) as a trigger. The DMS event recording is a process of storing image data taken during a predetermined period (for example, 30 seconds before and after) before and after receiving the DMS event recording signal (that is, before and after the occurrence of the DMS event). When the DMS event recording is completed, the radar detector 54 determines the driver's state again, and if it determines that the driver is dozing or looking aside, outputs the DMS event recording signal to the drive recorder 51, otherwise outputs the DMS event recording signal. do not.

The drive recorder 51 uses, for example, the first storage area to constantly record while the vehicle is driving, and uses the second storage area to record DMS events. The continuous recording is performed by overwriting the image data in the first storage area. That is, continuous recording is performed by writing image data to the entire first storage area and overwriting the old image data with new image data in order. Therefore, old image data of continuous recording may be lost by overwriting. The video recorded by DMS event recording is not lost by overwriting other image data. Therefore, overwrite recording is not adopted in DMS event recording. The first storage area and the second storage area are secured, for example, by logically dividing the storage areas in the same storage medium (for example, the memory card described above). In this case, the drive recorder 51 can prevent overwriting of the image data by saving the image data at the time of hiyari hat in a folder different from the folder in which the image data of the constant recording is saved by DMS event recording.

However, the first storage area may be reserved in the first storage medium, and the second storage area may be reserved in the second storage area. In this case, the first storage area and the second storage area are physically divided.

The image data of the event recording (so-called manual recording) performed in response to the operation of instructing the user to record the event button may be stored in, for example, a second storage area. When multiple events occur, the one that entered the event state first has priority. In the present embodiment, when the DMS event recording is performed during the manual recording, the drive recorder 51 stores the image data at the time of the near hat by the running manual recording.

Further, the radar detector 54 issues an alarm triggered by the reception of the DMS event signal. The radar detector 54 issues an alarm at the same time as the DMS event recording by the drive recorder 51. The warning is, for example, a voice warning, which includes a message to warn the driver, such as "Pip and be careful" when driving aside, and "Dangerous. Dangerous" when driving asleep. It is good. The alarm may be, for example, an alarm by screen display, and may be given by the screen display of FIG. 22 (a) in the case of sideways driving and by the screen display of FIG. 22 (b) in the case of dozing driving. The display of "02/32" in FIGS. 22 (a) and 22 (b) indicates that the event recording of 32 files is possible, whereas the event recording of 2 files is currently performed. Further, the alarm may be given by the light emission of the light emitting unit (for example, LED) provided in the radar detector 54. In this case, the radar detector 54 may change the light emitting state depending on whether the driver is driving aside or taking a nap. The radar detector 54 may change the voice and screen display according to at least one of the time when the eyes are closed and the number of warnings in the case of drowsy driving. The radar detector 54 stops the alarm when the driver turns to the front, and stops the alarm for drowsy driving when the driver opens his eyes.

The DMS event recording may be performed only when the alarm on the radar detector 54 continues for a certain period of time. When the radar detector 54 starts an alarm and warns for a certain period of time while continuing the alarm, it is preferable to output a DMS event recording signal to the drive recorder 51. In this case, the alarm starts, and DMS event recording starts after a certain period of time has elapsed. This is based on the idea that when a person falls asleep or drives aside for a short time, an alarm is given as a mild state, and when the driver continues for a certain period of time or longer, an alarm and an event are recorded as a severe state. As a result, the occurrence of unnecessary event recording is suppressed, and the effect of securing the storage area is also achieved.

At the time of an alarm, it is preferable to comprehensively judge not only the doze / sideways information detected by the DMS unit 55 but also the state of the vehicle to determine whether the warning is normal or within the normal range. Even if the continuous recording is set to overwrite, it can be set not to overwrite in order to raise the priority of recording at the time of a hiatus. For example, one or more of the following can be adopted.

(1) The radar detector 54 acquires vehicle speed information from the vehicle via the junction unit 52, performs an alarm and DMS event recording when the speed is equal to or higher than a predetermined speed, and performs an alarm and a DMS event when the speed is lower than the predetermined speed. It's a good idea not to record. The predetermined speed is, for example, 10 km / h or less. If the vehicle speed is low, there is a possibility that the driver is looking for a parking space in a parking lot or the like and looks around. In this case, since the sideways driving warning is not appropriate, unnecessary warnings and recordings are suppressed.

(2) The radar detector 54 may detect the running state of the own vehicle with a gyro sensor, for example, and if a predetermined condition indicating that the change in inclination is large is satisfied, it is preferable not to perform an alarm and DMS event recording. .. For example, there is a possibility that the driver is looking for a parking space at an intersection, a parking lot, or the like and looks around. In this case, since the sideways driving warning is not appropriate, unnecessary warnings and recordings are suppressed.

(3) In order to improve the detection accuracy of the DMS unit 55, the illuminance sensor provided in the radar detector 54 is provided as a countermeasure against the possibility that the camera of the DMS unit 55 may detect an image erroneously when the brightness changes suddenly. It is advisable to judge the change in brightness by. If the difference in illuminance is large, for example, it may cause a malfunction in the DMS that monitors the state of the driver or the like based on the image taken by the camera. Therefore, when the radar detector 54 determines that the change in the difference in illuminance is equal to or more than a certain value, it is preferable not to perform the warning and the DMS event recording. In this way, the alarm due to the false image detection is suppressed.

Situations where the illuminance is variable are likely to occur in tunnels during the day. Therefore, as a supplement to the information, the radar detector 54 may not issue an alarm based on the data indicating the position of the tunnel. Such data include, for example, map data and tunnel POI. The radar detector 54 may not perform alarms and DMS event recordings, for example, near the entrance or exit of a tunnel. In this way, unnecessary alarms and recordings are suppressed.

(4) DMS sideways / doze detection is also executed when it is necessary to change the direction of the line of sight, such as when changing lanes or when checking the mirror. Therefore, it is preferable that the radar detector 54 does not perform the alarm and the DMS event recording based on the blinker information such as the blinker line and the OBD2 adapter. In this way, unnecessary alarms and recordings are suppressed.

(5) The radar detector 54 may have the drive recorder 51 record for a certain period of time when the driver changes based on the recognition result of the driver's face. This is because an unusual driver is likely to be unfamiliar with driving. In this case, when the driver changes, the radar detector 54 may record from the start of the operation until a predetermined time elapses. This recording may be performed when the first driver is recognized, but may be performed when the driver is recognized as different from the previous one. In this way, in the case of an unusual driver, if there is a possibility of unfamiliar driving, it is possible to automatically record using the drive recorder 51.

In the present embodiment, depending on the setting, overwrite recording of continuous recording may be prohibited, or overwrite recording of event recording may be permitted. The vehicle may be a vehicle traveling on a railroad track or a track equivalent thereto, and such a vehicle includes a train, a monorail, a linear motor car, and the like.

[Modification example]
In each of the above-described embodiments, suppressing the operation of the parking monitoring function means that parking recording is not performed in the area where the parking position is memorized (cancellation area). This may be done at a lower quality than the normal recording performed when parking in an area where the parking position is not set. Poor quality recording may include slowing the frame rate, lowering the resolution, and recording when certain conditions are met rather than constantly recording. In addition, there are measures such as reducing the amount of memory capacity used and reducing battery consumption.

Further, in the above-described embodiment and the modified example, the operation of the parking monitoring function is suppressed at the set parking position, but the parking monitoring function that records the captured image when the vehicle is parked at the set parking position. Even if the vehicle is parked at the set parking position, it is preferable to have a parking monitoring function that suppresses the recording of images when a predetermined condition is satisfied.

Furthermore, in the above-described embodiment and modification, a predetermined area is stored like a set parking position, and different parking monitoring is performed inside and outside the area. However, for example, it is disclosed in the present specification. When combining various aspects of the present invention, the idea of using the area and the cancellation area is not essential, and parking monitoring is performed when the area is not registered and the area is operated, and parking monitoring is performed when the area is operated. It may be applied to a system having a function of not doing. For example, it can be applied to a device that does not have the concept of a cancel area in screen display, operation, power supply control, and the like.

The operation means for accepting the user's operation included in the drive recorder 2 is a collection of controls other than push-type buttons (for example, slide type), sensors such as touch sensors and proximity sensors, shooting means such as cameras, and microphones. It may be a sound means or the like. The operations include, for example, push, slide, touch, proximity, gesture, voice operation and the like.

The "parking position for suppressing the operation of the parking monitoring function" may be an area having a certain range, but may be a position at a certain point specified by a pinpoint.

The drive recorder 2 was a system without a display unit, but even if the system has a display unit, a light emitting unit may be provided separately from the display unit, or the display unit may function as a light emitting unit. Good. For example, even in a system provided with a display unit, if there is other information to be displayed on the display unit, it may be possible to notify the system by changing the background of the display unit or the light emitting state of a predetermined area, for example. For example, if the system is a drive recorder and the display unit is arranged integrally with the case equipped with a camera, if the drive recorder is small, the display unit is also small and it is difficult to see even if a message, icon, mark, etc. is displayed. , It becomes easier to recognize various changes in the display simply by changing the light emission state such as the light emission color. In the case of a drive recorder, it is often placed on the upper side of the vehicle interior space, such as above the windshield, and depending on the installation position, it may be placed on the back side of the rearview mirror, for example, when viewed from the driver's seat side. However, even in such a situation, it is easy to confirm the change in the light emitting state of the light emitting part, which is good. As described above, the presence or absence of the display unit may be used, but it is more preferable to apply it to a system without the display unit. The light emitting unit such as the LED 36 may be located at a position other than the embodiment as long as the light emitting unit is arranged at a position where the light emitting unit can be visually recognized by a user such as a driver sitting in the driver's seat or an operating driver. The operation method described in the above-described embodiment and specific modes such as a light emitting state, a screen, and an output sound are examples. The method of cooperation between the first control unit 31 and the second control unit 32 of the above-described embodiment is an example. A single control unit (processor or the like) may realize the functions of the first control unit 31 and the second control unit 32.
