Description

BACKGROUND(a) Technical field

[0001] The present invention / disclosure relates to a method for controlling an operation of a side and rear view camera monitoring system (CMS), and more particularly, to a method for controlling an operation of a side and rear view camera monitoring system that performs a turn-off operation of an in-vehicle display in response to driving the side and rear view camera monitoring system in consideration of a user's comfort. (b) Background technology

[0002] With the recent development of image capture and display technologies, a vision assurance device capable of replacing the existing side mirror for checking vehicle side and rear information has been developed, that is, a monitoring device that allows a driver to check side and rear image information captured by a camera by displaying the side and rear image information on a display.

[0003] In a vehicle equipped with a vehicle side and rear view monitoring camera system (CMS), small side cameras are mounted on the left and right sides of the vehicle instead of the existing side mirrors. Each of these cameras captures images of the vehicle's surroundings. Furthermore, the image signals captured by the side cameras are processed and displayed on side displays inside the vehicle, allowing the driver to check the side and rear conditions of the vehicle through the image information displayed on the display.

[0004] Fig. 1 shows a related art structure (prior art) in which an integrally mounted body 10 is mounted on a vehicle to provide a vehicle side and rear view camera monitoring system (CMS). Furthermore, the body 10 includes a camera 14, a display 12, and a controller as integrated components, and a camera housing 13 and a monitor housing 11 constitute a body 10.

[0005] When a related-art vehicle is equipped with the side and rear view observation camera monitoring system (CMS), while the vehicle is traveling, side and rear images of the vehicle are displayed on the display 12 to provide driving convenience. However, when the vehicle is not traveling and there is a driver's exit intention from the vehicle, a driver's entry intention into the vehicle, or a request to secure the driver's side and rear views, the driver's request is not met because the side and rear images of the vehicle are not displayed on the display 12.

[0006] In other words, when a request signal for securing the side and rear view is received from a driver in various situations as well as a situation in which the vehicle is traveling, a control method for displaying the side and rear surroundings of the vehicle cannot be provided.

[0007] Furthermore, US 2020 / 0 231 104 A1 discloses an apparatus and a related method for controlling operation of a side and rear view observation camera monitoring system, the apparatus comprising: a camera configured to capture side and rear images of a vehicle, a display configured to display the side and rear images captured by the camera, and a controller configured to detect a user's image-off signal and turn off the images of the display when the image-off signal is applied, wherein the controller is configured to receive the user's image-off signal, maintain the display in an ON state for a predetermined time, and turn off the electrical power of the display. Another apparatus and method for operating a side and rear view observation camera monitoring system is known from US 2020 / 0 339 049 A1. BRIEF EXPLANATION OF THE INVENTION

[0020] Fig. 2 shows a side and rear view observation camera monitoring system 100 according to an exemplary embodiment of the present invention / disclosure. The side and rear view observation camera monitoring system 100 includes a camera 110, a display 120, and a controller 130. The camera 110 of the present invention / disclosure may include a movable lens (not shown) movable to vertical and lateral positions based on a central axis, and a direction of the movable lens is adjustable by a direction adjustment knob (not shown) installed in a vehicle.

[0021] Furthermore, an upper end portion of a linear or circular extension extending forward (toward a rear side of the vehicle) may be formed on a housing of the camera 110. Thus, the extension may serve as a shade or umbrella that protects the movable lens of the camera 110, thereby enabling a driver to ensure a clear field of view while the vehicle is traveling, regardless of rain or snow. Furthermore, side and rear images of the vehicle captured by the camera 110 are provided to the driver via the in-vehicle display 120. Since the display 120 of the present invention / disclosure is located in the vehicle as described above, the display 120 may be a component located in an A-pillar of the vehicle or on a window thereof.

[0022] The display 120 may be formed of a liquid crystal display (LCD), a light-emitting diode (LED), or an organic light-emitting diode (OLED). Preferably, the display 120 of the present invention / disclosure may be formed of an OLED embedded in an inner surface of an A-pillar or a door of the vehicle. Furthermore, since the controller 130 of the present invention / disclosure displays the side and rear images received from the camera 110 on the display 120, an image display angle, image display height, or width can be adjusted according to a user request. If a failure occurs in the camera 110 or a connecting component of the vehicle connected to the camera 110, the controller 130 of the present invention / disclosure can perform a fail-safe function.

[0023] In the apparatus for controlling an operation of the side and rear view observation camera monitoring system 100 according to the present invention / disclosure, the controller 130 may be configured to receive electric power through a battery configured integrally with the vehicle and a battery mounted on the side and rear view observation camera monitoring system (CMS) 100, and electric power for driving the side and rear view observation camera monitoring system (CMS) 100 may be supplied through a plurality of relays connected to the battery and configured to correspond to each component of the controller 130.The control device 130 may be configured to receive a door opening / closing state of the vehicle, a start state thereof, and a door locking state thereof through a connection with a vehicle control device arranged in the vehicle, and perform on / off control of the display 120.

[0024] According to the present invention / disclosure, the camera monitoring system (CMS) 100 is configured to automatically adjust an on / off of the display 120 by the controller 130 based on a state of the vehicle without separately having an on / off switch of the display 120.

[0025] Fig. Figure 3 shows a configuration of the controller 130 of the side and rear view surveillance camera monitoring system (CMS) 100 according to the present invention / disclosure. As an exemplary embodiment of the present invention / disclosure, the side and rear view surveillance camera monitoring system (CMS) 100 includes the controller 130, a microcontroller (MCU) 131, and a signal modification and protection circuit 132.

[0026] The signal modification and protection circuit 132 of the present invention / disclosure may be configured to perform a function of receiving a plurality of signals generated by the vehicle, and thereby receiving an ignition signal (IGN), a vehicle door signal, a switching signal of the side and rear view surveillance camera monitoring system 100, and a vehicle door opening / closing signal. The received signals are transmitted to the MCU 131 by the signal modification and protection circuit 132.

[0027] Furthermore, in response to the signals transmitted to the MCU 131, the MCU 131 may be configured to operate a controller of a digital signal processor (DSP) and the DSP. As described above, when the side and rear view images are displayed on the display 120, a controller of the side and rear view observation camera monitoring system 100 may be operated, electrical power may be supplied to the side and rear view observation camera monitoring system 100 through the controller, and image signals may be processed. In this way, the side and rear images may be displayed on the display 120 according to the user's requirements. Furthermore, the plurality of received signals may be transmitted to an MCU controller 133.When conditions of a smart key, an ignition signal, a door opening / closing signal, and a switching signal of the side and rear view observation camera monitoring system 100 are satisfied, the MCU 131 is supplied with electric power to operate the side and rear view observation camera monitoring system 100.

[0028] Furthermore, as an exemplary embodiment of the present invention / disclosure, a switch of the side and rear view surveillance camera monitoring system 100 is a component located in the vehicle and directly connects a user request for securing the side and rear view to the side and rear view surveillance camera monitoring system 100. Specifically, the switch connected to the side and rear view surveillance camera monitoring system 100 is a component that is maintained in an OFF state by default. To allow the user to operate the side and rear view surveillance camera monitoring system 100, the switch may be maintained in an OFF state unless the switch is maintained in an ON state.

[0029] Fig. 4 is a flowchart illustrating a process for switching the display 120 to an OFF state in response to a user's image-off signal applied by the controller 130, according to an exemplary embodiment of the present invention / disclosure. In an ON state of the vehicle's display 120, the controller 130 may be configured to determine whether the user's image-off signal is received (S100).

[0030] In an operation of receiving the image-off signal, the controller 130 may be configured to determine a vehicle start condition to determine whether a door lock input signal of a wireless vehicle key (FOB) is applied or a gear shift input is actuated to a stop state. Specifically, when a vehicle stop state input is actuated in an ignition-ON state or a door lock input signal of the wireless vehicle key is received in an ignition-OFF state, the controller 130 of the present invention / disclosure may be configured to determine whether the display 120 is switched to the OFF state (S200).

[0031] In contrast, the controller 130 of the present invention / disclosure may be configured to enter a flip input state of the side and rear view surveillance camera monitoring system CMS 100 regardless of an ignition condition. When the user performs a flip input of the side and rear view surveillance camera monitoring system 100, the controller 130 may be configured to determine whether the display 120 is switched to the OFF state. In other words, in the exemplary embodiment of the present invention / disclosure, the user's application of the image off signal includes the door lock input of the wireless vehicle key, the flip input of the side and rear view surveillance camera monitoring system 100, or the vehicle stop state input (S200).

[0032] If a signal determined based on the application of the user's picture-off signal is detected, the controller 130 may be configured to switch the display 120 to the OFF state after a set time has elapsed (S300). After the display 120 is switched to the OFF state, the controller 130 may be configured to determine whether the user's picture-on signal is applied, and in response to determining that the picture-on signal is applied, the controller 130 may be configured to switch the display 120 to the ON state (S400). If the user's picture-on signal is not applied, the controller 130 may be configured to again determine whether the user's picture-on signal is applied for a predetermined waiting time (S500).

[0033] Since the application of the user's image-on signal may include a fold-out request signal of the camera monitoring system 100, the controller 130 may be configured to switch the display 120 to the ON state when the user's fold-out request is actuated with respect to the camera monitoring system 100. As described above, according to the present invention / disclosure, the controller 130 may be configured to switch the display 120 to the ON state to provide a rear view to the user even after the display 120 is switched to the OFF state when the fold-out input of the camera monitoring system 100 is applied as a user's image-on signal application request.

[0034] As described above, the controller 130 of the present invention / disclosure may be configured to determine whether the user's image-off signal is applied, and in response to determining that the user's image-off signal is applied, the display 120 may be maintained in the ON state for a preset time, and after the preset time has elapsed, the electrical power of the display 120 may be turned off.

[0035] Since the user's screen-off signal can be received through a connection to the vehicle control device disposed in the vehicle, the control device 130 can be further configured to receive a vehicle door opening / closing state, determine whether the door lock input signal of the wireless vehicle key is applied, and receive a gear position. In summary, since the display 120, which does not require a separate ON-OFF switch, is provided, the control device 130 according to the present invention / disclosure can be configured to automatically determine whether electrical power is applied to the display 120 in response to a change in the vehicle's state.

[0036] Fig. 5 is a flowchart illustrating a process for determining whether the user's screen-off signal is applied according to the vehicle's ignition state, according to an exemplary embodiment of the present invention / disclosure. To determine whether a first user's screen-off signal is applied, the controller 130 may be configured to determine an ignition state of the vehicle (S210). In the vehicle's ignition-off state, the controller 130 may be configured to determine whether a vehicle door lock signal (a lock signal) is input from the wireless vehicle key (S211). When the vehicle door lock signal is applied from the wireless vehicle key (S211), the controller 130 may be configured to immediately switch the display 120 to the OFF state (S213).

[0037] Otherwise, if the vehicle door lock signal is not applied from the wireless vehicle key (S211), the controller 130 may be configured to switch the display 120 to the ON state for a first set time and determine whether a door opening is input during the first set time (S212). If the door opening is not operated during the first set time, the controller 130 may be configured to switch the display 120 to the OFF state after the first set time has elapsed (S213). If the door opening is input during the first set time, the display 120 may be maintained in the ON state (S212), and the controller 130 may be configured to again determine whether a lock signal from the wireless vehicle key is applied (S211). In the present invention / disclosure, the first set time may be set to 120 seconds.

[0038] As described above, in an ignition OFF state, since the controller 130 switches the display 120 to the OFF state in response to a door lock input of the wireless vehicle key, the controller 130 may be configured to detect a vehicle stop state input of a transmission in the ignition ON state to determine whether the display 120 is switched to the OFF state. When a gear of the transmission is input to a P speed (S214) in the ignition ON state (S210), the controller 130 may be configured to maintain the display 120 in the ON state for a third set time (S215) and display a message to the user indicating that the display 120 is switched to the OFF state (S216). As an example of the present invention / disclosure, the third set time may be set to 600 seconds.

[0039] The message may be displayed via one or more of a combination instrument, a display, an audio-video navigation (AVN) display, and the illumination of LED warning lights located in the vehicle, and a message display method includes any visual or audio method capable of conveying the message to the user through the vehicle. Subsequently, the controller 130 may be configured to switch the display 120 to the OFF state (S213).

[0040] Fig.6 is a flowchart illustrating a process for determining whether a flip input of the camera monitoring system 100 is being applied and switching the display 120 to the OFF state according to another embodiment of the present invention / disclosure. The controller 130 may be configured to determine whether the flip input of the camera monitoring system 100 is being operated by the user (S220), and in response to determining that the flip input is being operated, the controller 130 may be configured to transmit a display-off switching message (S221). However, if the flip input of the camera monitoring system 100 is not being operated, the display 120 may be maintained in the ON state (S100).The controller 130 may be configured to transmit the display off switching message (S221), switch the display 120 to the ON state for a second set time (S222), and then switch the display 120 to the OFF state (S223). More preferably, the second set time may be set to about five seconds.

[0041] As described above, the controller 130 may be configured to detect a vehicle start condition (ignition state) and the door lock input of the wireless vehicle key or a vehicle stop input state to switch the display 120 to the OFF state, or may be configured to detect whether the flip request of the camera monitoring system 100 is applied to switch the display 120 to the OFF state. Therefore, it may be possible to provide an apparatus and method for controlling an operation of a side and rear view observation camera monitoring system capable of reducing a power consumption rate applied to the display 120.

[0042] The present invention / disclosure can achieve the following effects according to a combination of the exemplary embodiments described above and a configuration described below and a usage relationship. According to the present invention / disclosure, the power consumption of a camera monitoring system (CMS) can be optimized according to various environments by an apparatus and method for controlling an operation of a side-view and rear-view observation camera monitoring system. Furthermore, according to the present invention / disclosure, there is an effect of providing a display control technique capable of satisfying regulations of the camera monitoring system based on a user scenario.

[0043] Although the exemplary embodiments of the present invention / disclosure are described with reference to the attached drawings, one skilled in the art to which the present invention / disclosure belongs can appreciate that the present invention / disclosure can be implemented in other specific forms without departing from the technical spirit and essential features of the present invention / disclosure.
