    (57) A screen camera system includes: left and right capture devices (1 L, 1 R); left and right display devices (2L, 2R); and a control device (5) which detects an anomaly of each of the left and right capture devices (1 L, 1 R) and which controls a display state of each of the left and right display devices (2L, 2R ) based on the detected anomaly. The control device (5) controls each of the left and right display devices (2L, 2R) individually so as to place the latter in a low power consumption state as a function of a state of the detected anomaly. .

    The invention relates to a camera-screen system which displays on a control screen images captured by cameras provided on the left and right sides of a vehicle.
    In recent years, a vehicle without a mirror has been considered. A screen camera system is proposed in the publication of Japanese patent application No. 2015-226233 (JP 2015-226233 A). Instead of the left and right exterior mirrors of a vehicle, the screen camera system is configured to include: left and right side cameras which respectively capture a rear area of the vehicle from the left and right side areas of this one ; and a control screen which is arranged in a position where an occupant (a driver) in a vehicle interior can visually identify the control screen and which displays images captured by the side cameras. The various occupants who not only include a driver but also include occupants in a passenger seat and a rear seat can visually identify the image displayed on the control screen, and thus, the screen camera system is extremely effective in ensuring safe movement of the vehicle.
    In such a screen camera system, in the event that an anomaly occurs in the system, in particular, an image capture operation of the side camera itself is not normally carried out, where a circuit image processing which performs signal processing of the image captured by the side camera undergoes a malfunction, or equivalent, the image displayed on a control screen is scrambled, the image is frozen (the image does not is not displayed as a video, and the last image continues to be displayed), or the image is no longer displayed. In particular, when the image on the control screen is blurred, the occupant can no longer accurately recognize the lateral zone towards the rear zone of the vehicle thanks to the control screen. When the image on the control screen is frozen, the occupant erroneously believes that the frozen image shows the side area towards the rear area of the vehicle at that time. In each case, there is a possibility that the occupant cannot accurately recognize the side area toward the rear area of the vehicle. In addition, in the case where the screen camera system is normally controlled even during the appearance of the anomaly in the system as described above, the control screen cannot display the image normally, but energy continues to be consumed. This is unfavorable in terms of saving energy in an electric vehicle, a hybrid vehicle, or the equivalent which has a battery as a power supply.
    The invention provides a screen camera system capable of ensuring the safety of a vehicle by preventing an occupant (a driver) from mistakenly identifying an image displayed on a control screen and performing a energy saving even when an anomaly occurs in the system.
    A screen camera system according to one aspect of the invention comprises: left and right capture devices configured to respectively capture images of left and right zones outside a vehicle; left and right display devices which display the images captured by the left and right capture devices; and a controller which detects an abnormality of each of the left and right capture devices and which controls a display state of each of the left and right display devices based on the detected anomaly. The controller individually controls each of the left and right display devices so as to place the latter (i.e., each of these) in a low power consumption state as a function of a state of the detected anomaly (or of a detected anomaly mode, or of a detected type of anomaly).
    In the above aspect, the screen camera system can further comprise a state detection device which detects a state of the vehicle. The control device can control each of the left and right display devices so as to place the latter in the low power consumption state according to a combination of the detected state of the vehicle and the state (or mode, type) of the detected anomaly.
    In the above aspect, the control device can control each of the left and right display devices in an off mode, a standby mode ("black out"), or a display mode as a state low energy consumption. In the above aspect, as an anomaly mode for each of the left and right capture devices, the control device can detect any one of a total failure state, a frozen state, and a degradation state of image quality. In the above configuration, the control device can control each of the left and right display devices so as to place the latter in an off mode, a standby mode, or a display mode, depending on a combination of a state where the vehicle is moving or stopped, a state where a driver is in or out of the vehicle, a state of flashing of each of the vehicle's left and right flashing lights , and a state detected from a state of total failure, a frozen state, and a state of degraded image quality. In addition, in the above aspect, the control device can stop the command to switch to the low energy consumption state by means of an operation by a driver.
    According to the invention, when the anomaly occurs in the capture devices, the display devices are controlled so as to be placed in the different display modes based on the state of the vehicle and the fault mode detected at that time. Consequently, safety is ensured and an incorrect identification of a peripheral environment of the vehicle by the occupant (a driver) is avoided by means of a display of the control screens, and the system is controlled so as to have low energy consumption.

    Next, a description of an embodiment of the invention will be made with reference to the drawings. Figure 1 is a schematic configuration diagram of a vehicle on which a screen camera system of the invention is mounted. No exterior mirror is mounted on the left and right sides outside the body of a CAR vehicle. Left and right cameras IL, IR are arranged respectively in an integrated manner with the left and right position lights L-SML, R-SML. Each of the position lights functions as a flashing light which indicates a direction of movement of the vehicle to the left or the right, that is to say a change of direction indicator. The left side camera IL captures an image from a left side area to a left rear area AL of the CAR vehicle. The right side camera l.R captures an image from a right side area to a rear right rear area of the CAR vehicle. In the following, the lateral cameras IL, IR can both be collectively called camera 1.
    Figure 2 is a schematic view of a dashboard DB of the CAR vehicle. In the drawing, three control screens are aligned in the horizontal direction. The one located in the center is a central control screen 2C, and a left side control screen 2L and a right side control screen 2R are arranged respectively at the left and right ends of the dashboard DB, i.e. in areas interior of the front left and right uprights. The central control screen 2C is configured here as a display screen for a NAV navigation system. The left side control screen 2L displays the image captured by the left side camera IL, and the right side control screen 2R displays the image captured by the right side camera IR. Hereinafter, the two lateral control screens 2L, 2R can collectively be called control screen 2.
    The left and right side cameras IL, IR and the left and right side control screens 2L, 2R described above are electrically connected to a body 10 of the screen camera system shown in FIG. 1. Via commands transmitted to this screen-camera system body 10, the display of the captured images is controlled. This body 10 of the screen camera system 10 will be described below.
    Figure 3 is an exploded perspective view of a schematic configuration of the left position light L-SML among the left and right position lights. A light housing is configured to include: a substantially rectangular base 101 which is a part of a vehicle body BD of the vehicle and which is attached to a left wing for example; and a translucent outer cover 102 which is fixed on this base 101 so as to cover a surface of said base 101. A light-emitting diode (LED) 103 as a light source for the side position light is disposed in a front area of the base 101 (with regard to the longitudinal direction, a longitudinal direction of the vehicle is used as a reference). The left side camera IL is arranged in a rear zone with a light protection wall 104 which is interposed between the light-emitting diode 103 and the left side camera IL. In said rear area of the base 101, a left cleaning device 6L configured to clean a rear surface of the outer cover 102 is arranged in a lower area of the left side camera IL. This left-hand cleaning device 6L is configured here to project air onto the rear surface of the outer cover 102 to remove the dust or the like which is fixed on said rear surface, and extends in a state where a nozzle 6a, by which the air is projected, is bent upwards from the rear. On the rear surface of the outer cover 102, an opening 105 which corresponds to the nozzle 6a is arranged in a lower part of an area which is opposite to an image capture area of the left side camera IL. In this way, the air, which is projected by the left cleaning device 6L, cleans the rear surface of the outer cover 102 through the opening 105. The right position light R-SML is arranged in the same way way. Although not shown, a right cleaning device 6R is arranged with the right side camera IR in a light housing provided for it. Hereinafter, the two left and right cleaning devices 6L, 6R can be collectively called cleaning device 6.
    Figure 4 is a block diagram of the configuration of the screen camera system (SCE) in the embodiment presented. The body 10 of the screen camera system 10 is provided with: an electronic camera control unit 3 which controls the left and right cameras IL, IR; and an electronic control screen control unit 4 which controls the left and right side control screens 2L, 2R. The camera 1 and the electronic camera control unit 3 constitute the capture device of the invention, and this electronic camera control unit 3 performs a signal processing of the signals captured by the left and right cameras IL, IR and transmits the captured signals as image signals to the electronic control screen control unit 4. The control screen 2 and the electronic control screen control unit 4 constitute the display device of the invention, and this electronic control screen control unit 4 performs signal processing of the image signals to convert them into image signals of the type which can be displayed on the control screen 2, and transmits the image signals to the left and right side control screens 2L, 2R.
    As an electronic control unit which executes a main control of the screen camera system, an electronic body control unit 5 which is mounted on the vehicle is used here in the body 10 of the screen camera system. This electronic body control unit 5 can control the electronic camera control unit 3 and the electronic control screen control unit 4 and can also control the left and right cameras IL, IR and the side control screens left and right 2L, 2R via the electronic control units 3, 4. This electronic body control unit 5 functions as a control device according to the invention.
    The electronic body control unit 5 comprises a cleaning device control device 51 which controls an operation of the cleaning device 6, that is to say an operation of the cleaning devices 6L, 6R for the left and right position lights L-SML, RSML. This cleaning device control device actuates the cleaning device 6 so that it cleans the rear surfaces of the outer covers 102 for the position lights.
    The electronic body control unit 5 also includes a system anomaly detection device which detects a system anomaly. This system anomaly detection device 52 detects a change in signal level of each of the image signals transmitted by the camera 1 to the electronic camera control unit 3, of the image signals processed in a processing device. signal processing of the electronic camera control unit 3, and image signals received by the electronic control screen control unit 4 from the electronic camera control unit 3, identifies the images based on the image signals, and detects an abnormality in the camera 1 or the electronic camera control unit 3 based on these level changes and a result of the image recognition. In other words, the system fault detection device 52 detects the fault in the system capture device.
    As a system anomaly, the following three anomaly modes are detected in the embodiment presented.
    “Degradation of image quality”: part of the image which is captured by camera 1 and displayed on the control screen 2 has a defect, such as being saturated in black or white. All or part of the image is in an unfocused state. There is an abnormality in the contrast or in a property of color rendering of the image.
    "Frozen": a state where a particular captured image remains displayed while the captured image must be displayed on the control screen 2.
    "Complete failure": a state where no image signal is transmitted by the camera 1 or the signal processing is not executed by the electronic camera control unit 3, and therefore the control screen 4 electronic control unit does not receive the image signal ίο, and the image cannot be displayed on the control screen 2.
    Several sensors are connected to the electronic body control unit 5. Here, as sensors, there is a vehicle speed sensor 7V which detects a vehicle speed of the vehicle, a seat sensor 7S which detects a occupant (a driver) who is seated in a driver's seat, and left and right light sensors 7L, 7R which respectively detect the on (flashing) states of the light emitting diodes 103 as position light light sources left and right. These sensors can collectively and simply be called sensors 7. A description of a detection operation of the sensors 7 will be made below.
    7V vehicle speed sensor
    The vehicle speed sensor 7V detects the vehicle speed of the vehicle and also detects the following (an example of a state detection device). "On the move": the vehicle is moving. "Stopped": the vehicle is stopped.
    7S seat sensor
    The seat sensor 7S detects if the occupant (the driver) is seated in the driver's seat and also detects the following (an example of a state detection device). "Present": the driver is seated on the driver seat. "Absent": the driver is not seated in the driver's seat.
    Fire sensors 7L, 7R
    The light sensors 7L, 7R detect the on states of the light-emitting diodes 103, which are the light sources of the left and right position lights, like flashing-off states of the left and right flashing lights (an example of a detection device state).
    "Right turn": the right flashing light flashes, and the vehicle will move forward while turning to the right. "Left turn": the left turn signal light flashes, and the vehicle will move in a left direction. "Straight ahead": the two left and right flashing lights flash or are not lit, and the vehicle is in a state of movement in a straight line, in other words, in a state where it does not turn to the left or to the right.
    When the system anomaly detection device 52 detects the system anomaly, the electronic body control unit 5 refers to detection signals detected by the sensors 7, then controls the control unit control screen electronics 4, controls display on control screen 2, and performs a system command. As the system command, the following "cleaner" command and "monitor screen command" are executed.
    Cleaning device control
    The electronic body control unit 5 actuates the cleaning devices 6 of the left and right position lights by means of a cleaning device control device 51 so that they clean the rear surfaces of the outer covers. As modes of this cleaning, "routine cleaning" in which cleaning is performed at a preset time and "controlled cleaning" in which cleaning is performed only when it is ordered are available.
    Control screen control (side control screens 2L, 2R) "Off": power supplies of camera 1, of camera electronic control unit 3, of electronic screen control unit 4, and the control screen 2 are stopped to stop the system.
    "Standby": the control screen 2 is placed in a standby (or stand-by) state, and the camera 1, the camera electronic control unit 3, and the electronic screen control unit 4 are controlled so as to be placed in energy saving states. In this state, the entire control screen 2 is displayed in black; however, the control screen 2 can instantly display the image when it is returned to a normal state.
    ÎO "Display": the control screen 2 operates normally and continues to display the image on the display screen.
    A description will be made of the command by the camera-screen system which has the configuration described so far with reference to the flow diagram of FIG. 6. In the process F1, in the initial configuration, the unit of electronic body control 5 controls the left and right side control screens 2L, 2R so as to display the images in a normal manner (SU).
    Next, the electronic body control unit 5 detects whether the vehicle is currently "in motion" or "stopped" from a detection output of the vehicle speed sensor 7V (S12). During "movement", the cleaning device controller 51 causes the cleaning device 6 to perform "routine cleaning" (S13). Here, cleaning is carried out intermittently at specified times, so as to remove dirt from the rear surface of the outer cover 102 for the position light.
    Next, the system anomaly detection device 52 detects the presence or absence of anomaly (S14). If it detects an anomaly, the system anomaly detecting device 52 determines the anomaly mode for the IL or IR side camera whose anomaly has been detected (S15). If the anomaly is "complete failure", the 2L or 2R control screen is controlled so as to place it "off" (S16). This means that, if the "complete failure" occurs for the left or right side camera IL or IR on the corresponding side, the control screen 2L or 2R on the corresponding side is controlled so as to place it in mode " off ". If the “complete failure” occurs for the two left and right cameras IL, IR, the two control screens 2L, 2R are controlled so as to place these in “off” mode. In this way, the 2L or 2R control screen on the corresponding side or the two 2L, 2R control screens do not display the images.
    If the anomaly is "degradation of image quality" in step S15, the left or right control screen 2L or 2R on the corresponding side is controlled to "display" the image (S17) . If the anomaly which has appeared for the two left and right control screens 2L, 2R is “degradation of image quality”, the two left and right control screens 2L, 2R are ordered to “display” the images. In this way, although the image quality is degraded, the 2L or 2R control screen on the corresponding side or the two 2L, 2R control screens display the side areas and the rear area. It should be noted that, in the case of this “degradation of image quality”, as indicated by a dotted line in FIG. 6, the cleaning device 6 can be controlled to carry out a “cleaning ordered ”(S19). When this "controlled cleaning" is performed, the rear surface of the outer cover 102 is cleaned again, and the "image quality degradation" which is caused by dust, a foreign body, or the like fixed on said rear surface is probably resolved. In this case, the anomaly is not detected in step S22 in the next loop. If a “frozen” image is detected in step S15, the system anomaly detection device 52 puts the left or right side control screens 2L or 2R on the corresponding side in “standby” mode (S18). If the left and right side control screens 2L, 2R on both sides are "frozen", the two control screens 2L, 2R are placed in "standby" mode. In this way, the entire control screen 2L or 2R on the corresponding side or the entire control screens 2L, 2R on both sides are displayed in black.
    Therefore, when an anomaly occurs on the capture device in the screen camera system during the movement of the vehicle, the display of the control screen 2 as a display section, for which the anomaly occurs, is controlled so as to be in "off", "display" or "standby" mode depending on the type or mode of anomaly. When one of the control screens is “off” or in “standby” mode, said control screen 2 cannot display the image. Consequently, the driver realizes that an anomaly has occurred for the capture device, and identifies the lateral zone and the rear zone of the vehicle by means of a display on the other control screen which displays the image in normal fashion. In this way, minimum security during the movement of the vehicle is ensured. Furthermore, during the “complete failure”, energy consumption by the camera 1, in which the anomaly occurs, the electronic camera control unit 3, the electronic control screen control unit 4 , and the control screen 2 is deleted. In “frozen” mode, the energy consumption by the control screen 2, in which which the anomaly occurs, is deleted.
    If the "complete failure" or "frozen" type anomaly occurs in the control screens 2 on both sides, the control screens 2 on both sides are placed in the "off" or "standby" state . Consequently, the driver reports them that an anomaly has occurred in the capture devices on both sides, and controls the rear area of the vehicle using a rear view mirror or equivalent, for example. Thus, in this case also, the energy consumption by the camera 1, the electronic camera control unit 3, the electronic control screen control unit 4, and the control screen 2 is eliminated.
    If there is a "stop" in step SU of the process F1, the process F2 in FIG. 7 is executed. The seat sensor 7S detects whether the driver is "present" or "absent" (S21). If the driver is "present", processing proceeds to an F3 process, which will be described below. If the driver is "absent" and the system fault detection device 52 detects a fault (S22), the mode of the fault is determined (S23). If the anomaly is "complete failure", the left or right side control screen 2L or 2R on the corresponding side is controlled so as to place it "off" (S24). If the "complete failure" occurs on the left and right side control screens 2L, 2R on both sides, the 2L, 2R control screens on both sides are controlled so that it is "off".
    If the anomaly is "degradation of image quality" in step S23, the left or right side control screen 2L or 2R on the corresponding side is placed in "standby" mode (S25). If “image quality degradation” occurs for the left and right side control screens 2L, 2R on both sides, the 2L, 2R control screens on both sides are placed in “standby” mode. In this way, the entire control screen 2L or 2R on the corresponding side or the entire control screens 2L, 2R on both sides are displayed in black. In the case of this "image quality degradation", as in step S19 of the process F1, the cleaning device 6 can carry out the "controlled cleaning".
    If it is detected that the image is “frozen” in step S23, the system anomaly detection device 52 places the left or right side control screen 2L or 2R on the corresponding side in standby mode (S26). If the left and right side control screens 2L, 2R on both sides are "frozen", the two control screens 2L, 2R are placed in "standby" mode. In this way, the entire control screen 2L or 2R on the corresponding side or the entire control screens 2L, 2R on both sides are displayed in black.
    Therefore, in cases where the vehicle is stopped, the driver is absent, and the anomaly occurs for the camera screen system, a display of the control screen 2 on the side on which the anomaly occurs, is ordered to be in “off” or “standby” mode depending on the type of anomaly. In cases where the vehicle is stopped and the driver is absent, there is a low probability that the display of the control screen 2 will be necessary. Thus, the image is not actively displayed on the control screen 2. In this way, the energy consumption by the camera 1 on the side, for which the anomaly appears, the electronic control unit of camera 3, the electronic control screen control unit 4, and the control screen 2 while the vehicle is stopped is stopped.
    If “present” is detected in step S21 of the process F2, the process F3 in FIG. 8 is executed. If an anomaly is detected (S31), it is determined whether the type of anomaly is "complete failure", "frozen", or "degradation of image quality" (S32). If the type of anomaly is "complete failure", the left and right side control screens 2L, 2R are controlled so as to place it "off" (S33).
    If the type of anomaly in step S32 is “frozen”, the left and right side control screens 2L, 2R go into “standby” mode (S34).
    If the type of anomaly in step S32 is “degradation of image quality”, the fire sensors 7L, 7R respectively detect the flashing states of the left and right flashing lights and determine whether the Left and right flashing lights are in the "right turn", "left turn", or "straight ahead" states (S35). If the determination in this step S35 is "right turn", the right side control screen 2R is controlled to "display" the image, and the left side control screen 2L is placed in "standby" mode (S35a ). Furthermore, if the determination is “turn to the left”, contrary to the above, the left side control screen 2L is controlled to “display” the image, and the right side control screen 2R is placed in mode "Standby" (S35b). If the determination is “straight ahead”, the two left and right side control screens 2L, 2R are controlled to “display” the images (S35c).
    Just as has been described, when only the left or right flashing light flashes, there is a high possibility that the vehicle will turn to the flashing side. Therefore, although the image quality is degraded, the corresponding left or right side control screen 2L or 2R displays the side area and the rear area on said moving side. In this way, the driver identifies the side area and the rear area of
    S32, S33 can be determined to "crash the displayed image, and security can thus be ensured. In addition, the 2L or 2R control screen on the opposite side is placed in "standby" mode, so as to eliminate energy consumption.
    When the determination is "straight", there is a small possibility that the vehicle begins to move. However, there is a high possibility that the vehicle will start to move after a relatively short period. Consequently, the 2L, 2R control screens on both sides "display" the images, so as to give priority to safety over reduction of energy consumption. In this case, the need to control the control screens 2L, 2R to “display” the images is low while the vehicle is stopped. Thus, the control screens 2L, 2R can be placed in "standby" mode so that the control screens 2L, 2R display the images when the vehicle begins to move.
    It should be noted that, in the case of this "degradation of image quality" in the process F3, the cleaning device 6 can carry out the "controlled cleaning" as in step S19 of the process F1. more, in process F3, the determinations in the steps made simultaneously, and the complete "," frozen ", or the" degradation of image quality "in step S32 and the determination of" all right "," turn right ”, or“ turn left ”in step S33 can be combined. In this way, a process in which the control screens 2L, 2R are simultaneously controlled for "display", "standby", or "off" can be carried out. The manner of controlling the control screen in the system which has been described so far is summarized below in Figure 5. By executing this control screen command, monitoring using the screen control can be ensured while energy saving for the entire screen camera system can be achieved in the situation where the driver has to identify the side areas to the rear area of the vehicle and a situation where this recognition by the driver is preferred.
    Instead of the “standby” mode during the “degradation of image quality” in the embodiment presented, a “darkening” command of the control screen 2 can be executed so as to reduce the brightness during the “display” of the control screen 2. In particular, the control screens 2L, 2R can be controlled to “display” the images or be placed in “standby” mode in step S35 of the process F3, or the two control screens 2L, 2R can be controlled so as to be placed in "darkened" mode. This is advantageous for saving energy while ensuring security.
    The control of the screen camera system in the embodiment presented is simply an example of the invention. It goes without saying that embodiments other than those described in the embodiment presented can be realized. That is, the types of anomaly and the control screen control modes can be types of anomaly or control modes other than those described in the embodiment presented. In addition, the combination of these types of anomaly and these control modes can be appropriately changed.
    For example, in the invention, as vehicle states which are referred to in the control of the left and right side control screens, a state locked by a door key, the fact that the driver touches a steering wheel (a steering wheel), the seated state of the driver which is analyzed by an image using a vehicle cockpit camera, and the like can be adopted.
    For example, as shown in Figure 1, the invention can also be applied to a screen camera system which uses a rear camera IB provided in a rear section of the vehicle in addition to the left and right cameras. In this case, an image of an area AB captured by the rear camera IB is displayed on the central control screen 2C, and the images captured by the left and right side control screens 2L, 2R are synthesized so as to display matching images. In this way, the control screens 2C, 2L, 2R can be configured as control screens which display a wide area from the left and right sides to the rear of the CAR vehicle.
    It goes without saying that the invention can be applied to a position light which does not include a cleaning device. Even when the position light includes a cleaning device, this cleaning device can be configured to spray cleaning water with a nozzle and clean the surface of the outer cover for the position light. Alternatively, the cleaning device can be configured to clean the surface using air and cleaning water.
    In addition, the invention can also be applied to a vehicle which comprises left and right exterior mirrors. In particular, in a vehicle in which position lights and flashing lights are incorporated respectively and in one piece in the left and right exterior mirrors, the side cameras can be incorporated in these lights.
    Instead of being incorporated into the lights, the side cameras can be incorporated into a vehicle body, for example a wing, doors, or uprights.
    The screen camera system of the invention does not always have to be configured to constantly execute the energy saving command but can be configured to stop the energy saving command (command of low consumption of energy), for example, when the passenger actuates a switch, and can be configured so that the control screen displays the image permanently in a normal mode.
