Description

  The present invention relates to a camera monitoring system (hereinafter sometimes referred to as CMS) mounted on a vehicle.

  In a conventional vehicle, the rearview mirror is configured so that the driver can check the traffic situation behind the driver seat using a mirror attached to the fender part or the door part. On the other hand, as a substitute for a rearview mirror, a CMS configured such that the driver can check the traffic situation behind the driver from the driver's seat without using a mirror (see, for example, Patent Document 1) ) Has been proposed.

  Since CMS does not require a large mirror that meets the security standards required to drive a vehicle on public roads, it has the advantage of increasing the freedom of vehicle design and design. In addition, since the CMS is a system to which an electronic circuit is applied, electric power is required to operate the CMS. Therefore, CMS has a drawback that electric power is always required as compared with a rearview mirror using a simple mirror.

  When the vehicle is not used, the power consumption of the battery that supplies power to the CMS can be reduced by turning off the vehicle. However, even if the vehicle is turned off, if the driver is seated in the driver's seat, the driver needs to check the traffic situation behind the vehicle. Specifically, when the driver finishes driving the vehicle and opens the door to get out of the vehicle, the driver checks traffic conditions around and behind the vehicle so that the door of the vehicle does not contact other passing vehicles. There is a need to.

  Therefore, even when the vehicle is turned off, it is necessary to devise to operate the CMS. Specifically, the conventional CMS starts operation in conjunction with turning on the vehicle, or starts operation in accordance with the operation of the driver such as the driver sitting at the driver's seat. It is configured. Since the conventional CMS has such a configuration, the driver can check the traffic situation behind the vehicle when necessary while suppressing power consumption when the CMS is not used.

JP 2009-83618 A

  Here, to prevent the driver driving the vehicle on which the CMS is mounted from having a sense of incongruity, an image is displayed on the monitor such that the CMS has a visual range equivalent to the visual range of the conventional rearview mirror. It is configured. In addition, regardless of the surrounding environment of the vehicle, in CMS, it is necessary to always display a stable image on the monitor. For example, even in the case of driving a vehicle under severe weather conditions such as a hot summer sky or a heavy snowstorm at midnight, in CMS, a stable image needs to be always displayed on a monitor.

  However, when driving a vehicle under the severe weather conditions as described above, deposits such as raindrops, snow, sand dust, dirt etc. adhere to the lens surface of the CMS camera, and as a result, the camera captures an image. There is a problem that the video to be displayed becomes unclear. That is, since the lens surface of the camera is much smaller than the mirror surface of the rearview mirror, the entire lens surface is likely to be covered with the deposit, and as a result, it may be difficult to determine the image displayed on the monitor .

  The present invention has been made in view of the problems as described above, and enables stable display of an image captured by a camera on a monitor even when driving a vehicle under various weather conditions. The purpose is to obtain a camera monitoring system.

The camera monitoring system according to the present invention is a camera monitoring system mounted on a vehicle, and includes a camera that captures an image, a recording device that records an image captured by the camera, and a monitor that displays the image captured by the camera. An attached matter removing device for removing the attached matter attached to the lens surface of the camera, an operation of the camera and the recording device , and a determination for whether or not the attached matter is attached to the lens surface. With the kimono determination information as an input, based on the attachment determination information, when it is determined that the attachment is attached to the lens surface, a camera monitoring ECU that removes the attachment by operating the attachment removal device; comprising a camera monitoring the ECU, when the vehicle is stopped, the continuous operation of the operation the camera is capturing an image, mosquitoes The images captured by La is recorded on the recording apparatus, when the vehicle is stopped, operation of the camera for photographing an image is to be switched to the intermittent operation from the continuous operation.

  According to the present invention, it is possible to obtain a camera monitoring system which stably displays an image captured by a camera on a monitor even when driving a vehicle under various weather conditions.

Also, by confirming the state of infrared rays, grasp the state of the occupant, such as whether the occupant is in the car, in which seat the occupant is seated, and whether the occupant is in a position other than the seat. Can do.

  The communication ECU 60 performs wireless communication with a communication terminal (not shown) possessed by the vehicle driver via the antenna 61. The driver can confirm or change the setting of the device controlled by the body ECU 10 using the communication terminal. For example, the setting of the lighting time of the room light 11 can be changed by the communication terminal so that the passenger can safely get on and off the vehicle in a dark environment immediately after the power of the vehicle is turned off. Further, the communication terminal can set the operation of the CMS 1 described later, and can confirm the video recorded by the recording device 6 described later.

  The wiper ECU 70 ensures visibility of the front window and the rear window by operating the washer 71 and the wiper 72 in accordance with an instruction from the body ECU 10. The body ECU 10 instructs the wiper ECU 70 to operate the washer 71 and the wiper 72 when detecting the driver's operation or when determining that the visibility of the window is poor. The body ECU 10 determines, based on the detection results of the raindrop sensor 12, the solar radiation sensor 13, the temperature sensor 51, the humidity sensor 52, and the infrared sensor 53, whether the visibility of the window is in a poor state.

  The keyless entry ECU 80 communicates with the body ECU 10 via the body control communication bus 300. The keyless entry ECU 80 wirelessly communicates with a key possessed by the driver via the antenna 82, and determines whether or not the key is a proper key that has been authenticated in advance. The body ECU 10 instructs the door ECU 20 to lock or unlock the door based on the determination result of the keyless entry ECU 80. Similarly, body ECU 10 fixes or releases steering (not shown) based on the determination result of keyless entry ECU 80. Thus, the body ECU 10 carries out a series of security ensuring operations.

The light ECU 90 turns on the lamp 91 when the vehicle travels at night, when the vehicle travels through a tunnel, or the like.

  Next, the CMS 1 in the first embodiment will be described. The CMS 1 includes a camera monitoring ECU 2, a camera 3, a monitor 4, a deposit removing device 5, and a recording device 6.

  The camera monitoring ECU 2 is connected to the body ECU 10 via the body control communication bus 300 and basically operates by being constantly supplied with power by the battery 200.

  The camera monitoring ECU 2 is connected to a camera 3 for capturing a surrounding image. The camera monitoring ECU 2 acquires an image of a wide field of view including the left and right of the vehicle, the rear of the vehicle, or the front of the vehicle from the camera 3. The installation position of the camera 3 may be any place where it can be installed due to the structure of the vehicle. Further, the camera 3 may be installed at a plurality of locations so that the left and right of the vehicle, the front and rear of the vehicle, and the like can be photographed.

  The camera 3 has a wide viewing angle as compared with the conventional rearview mirror, and captures an image. The monitor 4 displays an image taken by the camera 3. The camera monitoring ECU 2 uses the detection result of the infrared sensor 53, the detection result of the seating detector 42, the open / close state of the door, the determination result of the keyless entry ECU 80, etc. to determine whether the driver is inside the vehicle. If the camera monitoring ECU 2 determines that there is a driver in the vehicle, the camera monitoring ECU 2 displays an image on the monitor 4. The display of the image on the monitor 4 may be stopped by the driver's instruction. Moreover, you may use the panel meter display 30 as the monitor 4 which displays an image | video.

  Here, the image displayed on the monitor 4 will be further described with reference to FIGS. 2 and 3. FIG. 2 is an explanatory diagram showing the viewing range of the camera 3 of the CMS 1 according to Embodiment 1 of the present invention. FIG. 3 is an explanatory view showing a comparative example of FIG.

  In FIG. 2, an example of a viewing range of the camera 3 of the CMS 1 mounted on the vehicle 400 is illustrated, and the camera 3 captures an image of the viewing range. Further, in FIG. 3, as a comparative example, an example of the visible range of the rearview mirror 401 mounted on the vehicle 400 on which the CMS 1 is not mounted is illustrated, and the driver uses the rearview mirror 401 to view the visible range. Can be confirmed.

  The camera monitoring ECU 2 corrects the image so as to be equivalent to the visible range of the conventional rearview mirror (visible range shown in FIG. 3) when displaying the image taken by the camera 3 on the monitor 4. The corrected image is displayed on the monitor 4.

  That is, when an image of the visible range (the visible range shown in FIG. 2) of the camera 3 is displayed on the monitor 4, the image becomes a very wide image, and hence the driver who is used to the conventional rearview mirror May cause confusion. Therefore, the camera monitoring ECU 2 makes the range of the video displayed on the monitor 4 correspond to the visible range shown in FIG. 3 by correcting the video taken by the camera 3 unless the driver changes the setting in particular. .

  Note that a conventional technique may be applied as a method for correcting the video as described above. For example, the following method may be used. That is, a method is used in which a video shot by the camera 3 is cut out in a cutout region to correct the video shot by the camera 3 to a video corresponding to the viewing range shown in FIG. This cutout region depends on the shape of the vehicle, the installation location of the camera 3, the viewing angle of the camera 3, and the like. Further, since the image captured by the camera 3 of the CMS 1 is an image having a wide viewing angle, large distortion occurs in the peripheral portion of the image captured by the camera 3. Therefore, not only the above-described method but also a conventional wide-angle lens image distortion correction technique is used.

  The camera monitoring ECU 2 may adjust the correction range of the image according to the driver's designation. Further, the camera monitoring ECU 2 recognizes the possibility of the vehicle contact starting from the start of the steering wheel operation, etc., particularly when the driver indicates the intention of the lane change by the blinker etc. in the situation where the vehicle is recognized sideways. In such a case, the image displayed on the monitor 4 may be processed. Specifically, the camera monitoring ECU 2 attaches information indicating alerting, an obstacle, or enlarges the video. When the operation of the vehicle is a specific operation such as the backward movement of the vehicle, the low speed traveling of the vehicle, etc., the camera monitoring ECU 2 displays an auxiliary sign, a guideline, an obstacle, etc. in the image displayed on the monitor 4 for driving assistance. You may attach the information to show.

  When the operation of the vehicle is the above-described specific operation, the camera monitoring ECU 2 may check the operation status of the vehicle controlled by the drive ECU 100 and may automatically switch the correction range of the image.

  As described above, when the vehicle is performing a specific operation, the camera monitoring ECU 2 performs the back-up image from the image obtained by correcting the image displayed on the monitor 4 to be the same as the viewing range of the back-mirror It is also possible to switch to an image corrected so as to be a wider visible range than the visible range of the mirror, and attach information to the switched image.

  The camera monitoring ECU 2 may perform the exposure correction of the camera 3 properly by obtaining the state of the lighting device 91 from the light ECU 90.

  In the conventional rearview mirror, a door mirror opening and closing mechanism for opening and closing the rearview mirror and a mirror heater are provided. The door mirror opening and closing mechanism is applied to the camera 3 and the attached substance removing device 5 is provided. A mirror heater may be used. Also, the conventional rearview mirror is provided with a mirror fine adjustment mechanism for adjusting the direction of the mirror, but the function of this mirror fine adjustment mechanism is to monitor the image captured by the camera 3 by the camera monitoring ECU 2. This corresponds to the function of adjusting the display range. Therefore, by setting the adjustment range by using the operation switch 23, the same operability as that of the conventional rearview mirror may be secured.

  Returning to the explanation of FIG. 1, the attached matter removing device 5 removes the attached matter attached to the lens surface of the camera 3 according to the control of the camera monitoring ECU 2. For example, raindrops, snow, dust, dirt, etc. can be considered as the deposits attached to the lens surface of the camera 3.

  The attached matter removing device 5 may be configured in any manner as long as it can remove the attached matter attached to the lens surface, but as a specific configuration example, a configuration using a washer and a wiper, ultrasonic waves, etc. The structure using the mechanism which generates the vibration of, the structure using a heater, etc. are mentioned. When adopting a configuration using washers and wipers as the configuration of the deposit removal device 5, the washers and wipers may be in a form shared with those for the front window and the rear window, or may be separate for the camera 3. The form provided in may be sufficient.

  In addition, if the vehicle is stopped for a long time, the deposit removing device 5 may turn off the power of the device in order to suppress the consumption of the battery 200.

  The camera monitoring ECU 2 receives deposit determination information for determining whether or not the deposit is attached to the lens surface of the camera 3, and the deposit is detected on the lens surface based on the input deposit determination information. When it is determined that the adhering material is attached, the adhering material removing device 5 is operated to remove the adhering material on the lens surface. As long as the camera monitoring ECU 2 can determine whether or not the attached matter is attached to the lens surface, any information may be used as the attached matter determination information, but as a specific example of the attached matter determination information The following information can be mentioned.

  As a first example, the attached matter determination information includes the detection result of the raindrop sensor 12, the detection result of the solar radiation sensor 13, the detection result of the temperature sensor 51, the detection result of the humidity sensor 52, and the detection result of the infrared sensor 53. It is. In this case, the camera monitoring ECU 2 uses the detection result of the raindrop sensor 12, the detection result of the solar radiation sensor 13, the detection result of the temperature sensor 51, the detection result of the humidity sensor 52, and the detection result of the infrared sensor 53. It is determined whether or not the deposit is attached to the lens surface.

  Specifically, the camera monitoring ECU 2 detects the detection result of the raindrop sensor 12, the detection result of the solar radiation sensor 13, the detection result of the temperature sensor 51, the detection result of the humidity sensor 52, and the detection result of the infrared sensor 53. If the set conditions are satisfied, it is determined that the deposit is attached to the lens surface. The setting conditions are set in advance, and specific numerical values are obtained through experiments and the like.

  Hereinafter, a method of determining the setting condition will be described. The setting conditions correspond to the conditions under which the lens surface of the camera 3 condenses. In general, the lens surface condenses on the condition that the temperature near the lens surface is lower than the dew point temperature obtained from the temperature and relative humidity. This dew point temperature varies depending on various factors such as direct solar radiation to the lens, the outside air temperature, and the temperature of the camera body (vehicle) itself. Therefore, the dew condensation condition on the lens surface cannot be expressed by a qualitative mathematical formula or the like and needs to be obtained experimentally. Therefore, the detection result of each sensor when the lens surface condenses is obtained in advance, and the above setting condition is determined using this detection result.

  Thus, based on the detection results of the raindrop sensor 12, the solar radiation sensor 13, the temperature sensor 51, the humidity sensor 52, and the infrared sensor 53, the camera monitoring ECU 2 inputs the attached matter determination information. It is determined whether or not the deposit is attached.

  As a second example, the attached matter determination information is an image captured by the camera 3. In this case, the camera monitoring ECU 2 uses the image captured by the camera 3 to determine whether or not the attached matter is attached to the lens surface.

  Specifically, if a deposit adheres to the lens surface, a specific noise component caused by the deposit is included in the image. Therefore, if the camera monitoring ECU 2 detects a specific noise component from the video imaged by the camera 3, the camera monitoring ECU 2 determines that the deposit is attached to the lens surface.

  Further, if an adhering substance adheres to the lens surface, even if the vehicle moves, there is no change in a certain part of the image. Therefore, the camera monitoring ECU 2 determines that the attached matter is attached to the lens surface if there is no change in a certain portion of the image captured by the camera 3 even if the vehicle moves.

  As described above, the camera monitoring ECU 2 determines whether the attached matter is attached to the lens surface of the camera 3 based on the image captured by the camera 3 input as the attached matter determination information.

  As a third example, the adhering matter determination information is the operating condition of the air conditioner ECU 50 that controls air conditioning. In this case, the camera monitoring ECU 2 determines, based on the operating condition of the air conditioner ECU 50, whether or not the attached matter is attached to the lens surface.

  Specifically, when the season is winter and the air conditioner performs an operation of emitting warm air according to the control of the air conditioner ECU 50, the lens surface of the camera 3 is considered to be cold, so condensation on the lens surface is considered. Therefore, the camera monitoring ECU 2 determines that the adhering matter is attached to the lens surface when the air conditioner ECU 50 controls the air conditioner to emit hot air.

  As described above, the camera monitoring ECU 2 determines whether the attached matter is attached to the lens surface of the camera 3 based on the operation state of the air conditioner ECU input as the attached matter determination information.

  The recording device 6 is configured by, for example, a memory, a hard disk, and the like. The recording device 6 is connected to the camera monitoring ECU 2 and records images taken by the camera 3. Since power is constantly supplied by the battery 200, video can be continuously recorded in the recording device 6. In addition, during driving of the vehicle, even if intense acceleration and impact caused by driving the vehicle are detected, video is recorded in the recording device 6 for a while, so before and after the accident Can be maintained and managed as accident evidence.

  It is desirable that the recording device 6 be configured to be removable from the vehicle. That is, when an accident occurs, there is a high possibility that the vehicle can not operate normally after the accident, so it is desirable that the recording device 6 can be easily attached and detached from the CMS 1 so that only the recording device 6 can be taken out alone. Further, it is desirable that the presence of the recording device 6 can be easily determined by painting or the like on the recording device 6. Furthermore, information such as the speed of the vehicle and the operation state of each part of the vehicle may be recorded in the recording device 6 via the drive ECU 100.

  While the vehicle is stopped, abnormal events such as opening / closing of the door, seating detection by the seating detector 42, operation to the power seat 41 or the like occur although the keyless entry ECU 80 can not recognize the proper key authenticated beforehand. In this case, the video taken by the camera 3 may be recorded in the recording device 6. Further, when such an abnormal event occurs, the camera monitoring ECU 2 may instruct the communication ECU 60 to transmit a warning to the communication terminal together with the video recorded in the recording device.

  Thus, the camera monitoring ECU 2 may instruct the communication ECU 60 to transmit the video recorded in the recording device 6 to the communication terminal. In addition, when the keyless entry ECU 80 determines that the key is not a proper key, the camera monitoring ECU 2 may instruct the communication ECU to transmit a warning to the communication terminal together with the image recorded in the recording device 6.

  When the vehicle is stopped, the camera monitoring ECU 2 records the image captured by the camera 3 as an operation in which the camera 3 captures an image and the camera 3 continuously captures an image. May be recorded.

  In addition, in order to reduce the consumption of the battery 200 mounted on the vehicle, when the vehicle is stopped, the camera monitoring ECU 2 performs an operation in which the camera captures an image and a continuous operation in which the camera 3 captures an image continuously. Alternatively, the camera 3 may switch to an intermittent operation in which the video is taken intermittently. In addition, when the vehicle is stopped, the camera monitoring ECU 2 switches from the continuous operation to the intermittent operation, and the change in the movement etc. is seen if the change in the movement etc. is not seen in the image taken by the camera 3 If it is possible, the intermittent operation may be switched to the continuous operation. Therefore, it is possible to suppress the consumption of the battery 200 while recording the video necessary for ensuring the security of the vehicle without leaking to the recording device 6.

  In the situation where the driver does not drive the vehicle, the camera monitoring ECU 2 operates the monitor 4 on the premise that the following conditions are satisfied, and the driver is constantly asked the surroundings of the vehicle for the monitor 4 It may be displayed. The above conditions are that the keyless entry ECU 80 confirms that there is a key in the vehicle, and that the seat ECU 40 confirms that the driver is seated at the driver's seat from the detection result of the seating detector 42, The air conditioner ECU 50 is to confirm that the occupant is in the vehicle by the infrared sensor 53.

  In addition, it is possible to alert the passenger on the passenger seat or the rear seat to contact with a passerby or another vehicle or contact between an adjacent vehicle or a wall and a door by an unexpected door opening operation. Good. In this case, the alerting using the monitor 4 or the panel meter display 30 or the alerting by the alarm sound is performed.

  As described above, according to the first embodiment, the camera monitoring system receives, as input, the adhering matter determination information for determining whether the adhering matter adheres to the lens surface of the camera. Based on the above, when it is determined that the attached matter is attached to the lens surface, the attached matter removing device is operated to remove the attached matter.

  As a result, even when driving a vehicle under various weather conditions, regardless of whether it is rain, snow, fog or day or night, it is possible to stably display an image captured by a camera on a monitor.

  By using a camera having a wider viewing angle than that of a conventional rearview mirror, it is possible to capture an image at a wide viewing angle, so that design constraints such as where and how many cameras are arranged on the vehicle are relaxed, and as a result The degree of freedom in vehicle design is improved. In addition, when the vehicle is stopped, when the driver is seated in the driver's seat without driving, and when moving the vehicle to the parking space (so-called garage storage), CMS is effective as a means for confirming traffic conditions and confirming the positional relationship with adjacent cars or walls.

  Furthermore, the video imaged by the camera is provided to the driver through the monitor and can be recorded in the recording device. Therefore, even if a traffic accident or the like occurs during driving, an image having a wide viewing angle is recorded in the recording device, and therefore, it is possible to obtain information that is effective in determining the cause of the accident or the like. In addition, even in a situation where driving is not performed such as parking, by monitoring the image on the recording device, it is possible to monitor the security of the car such as theft or mischief measures.
