Description

The Image Surveillance Apparatus For Vehicle Sharing The Electronic Control Unit

The present invention relates to a vehicle video monitoring apparatus sharing an electronic control unit, and more particularly, a plurality of cameras and a plurality of vehicle video display apparatuses are connected to one ECU and can be controlled through one ECU, and further The present invention relates to an image monitoring apparatus for a vehicle capable of outputting all images of a camera through an image display apparatus for another vehicle even if one image display apparatus for a vehicle fails.

In general, while it is easy to monitor the front of a vehicle from the driver's seat, it is relatively difficult to monitor the side or rear, so blind spots occur. occurs in the land.

The driver operates the vehicle while monitoring the surroundings, especially the blind spot, through one or more mirrors provided in the vehicle. There is a limit in promoting safe driving due to obstruction of vision.

Recently, a so-called CMS (Camera Monitor System) technology has been proposed in which a camera is installed in a vehicle and an image captured by the camera is displayed in the driver's seat of the vehicle to allow the driver to check obstacles around the vehicle.

In order to implement the CMS technology, a camera is generally installed in a side mirror of a vehicle, and an image display device for a vehicle is installed near the driver's seat so that the driver can easily check the image taken from the camera. In this way, the blind spots are reduced compared to the case where only the existing side mirrors are installed, thereby promoting safety, securing the driver's field of vision and reducing fatigue.

According to the CMS technology, a camera, ECU, and a vehicle image display device constitute a single vehicle video monitoring device. However, in the related art, when a plurality of cameras are installed, the video surveillance apparatus for a vehicle is installed separately from each other without being interconnected. Therefore, if only a camera is additionally installed, the image of the corresponding camera cannot be output, so a vehicle image display device must be additionally installed. In addition, if one video display device for a vehicle fails, the image of a camera connected to the video display device for a vehicle cannot be output even if shooting continues.

Advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and only these embodiments allow the disclosure of the present invention to be complete, and common knowledge in the technical field to which the present invention pertains It is provided to fully inform those who have the scope of the invention, and the present invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout.

Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used with the meaning commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, terms defined in a commonly used dictionary are not to be interpreted ideally or excessively unless clearly defined in particular.

The terminology used herein is for the purpose of describing the embodiments and is not intended to limit the present invention. In this specification, the singular also includes the plural, unless specifically stated otherwise in the phrase. As used herein, “comprises” and/or “comprising” does not exclude the presence or addition of one or more other components in addition to the stated components.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a part of a video monitoring apparatus for a vehicle according to an embodiment of the present invention.

As shown in FIG. 1 , an image monitoring apparatus for a vehicle according to an embodiment of the present invention includes a vehicle image display device 1 , a camera 2 , and an electronic control unit (ECU) 3 . In addition, the vehicle image display apparatus 1 includes a display board 10 and a display panel 20 .

The camera 2 is installed in the vehicle to photograph the outside of the vehicle. The image captured by the camera 2 is displayed through the vehicle image display device 1 installed inside the vehicle. The driver can secure a field of view through the output image to easily grasp an external situation and secure safety, such as avoiding obstacles. The camera 2 generally uses an imaging device such as a CCD (Charge Coupled Device) or CIS (CMOS Image Sensor). The camera 2 according to an embodiment of the present invention is preferably a digital camera that takes a two-dimensional image of 15 to 30 frames per second and outputs moving picture data by digital conversion, but is not limited thereto. If the camera 2 is not a digital camera, since the captured image is an RGB analog image signal, an ADC converter must be separately provided. However, if the camera 2 according to an embodiment of the present invention is a digital camera, an ADC converter is not required. In addition, since the camera 2 itself has a function of encoding an image, when the camera 2 takes an image, it is encoded immediately to generate compressed image data.

Recently, due to the interest in Ultra High Definition (UHD), which is an ultra-high-resolution video, the standardization of HEVC (High Efficiency Video Coding) for UHD video encoding has been completed, and the encoding efficiency has been improved by more than twice that of H.264/MPEG-4 AVC. As a codec for encoding the video, it is preferable to use MPEG4 or H.264/MPEG-4 AVC, which is mainly used recently, HEVC, etc. introduced above, but the present invention is not limited thereto, and various types of codecs may be used.

The electronic control unit (ECU) 3 can encode or decode an image by itself, and performs overall control of the image processing process. If the camera 2 itself is equipped with a function to encode an image, the image captured by the camera 2 is immediately encoded, and after the compressed image is transmitted to the electronic control unit (ECU) 3, the electronic control unit ( The decoding process is performed in the decoder 31 included in the ECU) 3 . Here, the decoding process is different from the re-decoding process performed in the display board 10, which will be described later, and is performed separately.

In general, the connection line between the electronic control unit (ECU) 3 and the vehicle image display device 1 has a small signal bandwidth. Therefore, in order to transmit the image to the vehicle image display device 1, the electronic control unit (ECU) 3 goes through the decoding and re-encoding process while the raw data of the image is downsized (Down Sizing) to It needs to be downscaled. When the above image is transmitted to the vehicle image display device 1, the display board 10 inside the vehicle image display device 1 goes through a re-decoding process to output a restored image and is displayed on the display panel 20 . Details of the re-decoding process in the display board 10 will be described later.

An electronic control unit (ECU) 3 receives inputs of various sensors mounted on the vehicle, and controls the driving of the vehicle as a whole. For example, the brightness of the image may be adjusted by determining day and night. Specifically, a sensor such as an illuminance sensor 54 mounted on a vehicle separately applies a signal to the electronic control unit (ECU) 3 . When the electronic control unit (ECU) 3 receives a signal from the sensor, it determines whether it is outdoors during the day or at night, and commands to adjust the brightness of the image. The brightness control command may instruct the display board 10 to adjust the brightness of pixels in an image processing process including decoding of an image. Alternatively, the electronic control unit (ECU) 3 may directly instruct the display panel 20 to adjust the brightness of the backlight. If the outdoors is daytime, the brightness of the output image can be brightened to about 500 cd/m2 or more, and when the outdoors is nighttime, the brightness of the output image can be dimmed to about 100cd/m2 or less, but the above figures are exemplary and not limited thereto. It can be set in various ranges.

The electronic control unit (ECU) 3 may further include a storage unit (not shown). A storage unit (not shown) stores the encoded image data or stores various final contents. In order to miniaturize the image display apparatus for a vehicle, it is preferable to use a flash memory, which is a non-volatile memory having a small volume, as the storage unit (not shown), but the present invention is not limited thereto, and various memory devices may be used.

The electronic control unit (ECU) 3 may further include a voice processing module (not shown). If the camera 2 is equipped with a microphone, the camera 2 may separately record a voice outside the vehicle. The recorded voice data may also be encoded by the camera 2 itself, and the encoded compressed voice data is decoded and other voice processed in a voice processing module (not shown). The voice-processed restored voice may be output to the speaker 30 according to a command of the electronic control unit (ECU) 3 . Alternatively, a guide message or a simple buzzer sound may be previously stored as voice data, and may be output to the speaker 30 after being processed through a voice processing module (not shown).

The display panel 20 visually displays an image restored by decoding and image processing under the control of the image control unit 103 included in the display board 10 so that a user can monitor it. The display panel 20 may use various methods such as LCD, LED, OLED, and furthermore, may have a function of a touchable touch panel.

The vehicle image display apparatus 1 may be connected to various sensors and systems mounted on the vehicle through network communication 5 . The sensors and systems of the vehicle include an accelerator sensor 51 , a brake system 52 , a wheel speed sensor 53 , an illuminance sensor 54 , a lamp adjustment system 55 , and the like.

The accelerator sensor 51 is a sensor that measures the pressure applied to the accelerator pedal to adjust the RPM of the engine, and the wheel speed sensor 53 is a sensor that detects the amount of rotation of the wheels of the vehicle or the number of rotations per unit time. ) is constructed using elements, etc. The brake sensor 522 is a sensor that detects the amount of operation of the brake pedal. The brake sensor 522 is connected to network communication via the brake system 52 . The shift lever switch 57 is a sensor or switch that detects the position of the shift lever, and is configured using a displacement sensor or the like. The illuminance sensor 54 is mounted on the outside of the vehicle to determine the day and night by measuring the amount of light received, and is configured using a photocell or a phototube.

The brake system 52 is an electric brake system including a brake assist that enhances braking force using the driving unit 521 and an anti-lock braking system (ABS) that suppresses locking of the brake. The lamp control system 55 is a system that adjusts the amount of light emitted by the vehicle according to the illuminance sensor 54 or a user's control input. The external system 56 is an optional system that connects an inspection system or an adjustment system used in production, inspection, and maintenance of a vehicle from the outside through a connection connector, etc., and is not always mounted on the vehicle, but can be detached.

The sensors and systems described above are exemplary, and the connection form is also exemplary. Therefore, the present invention is not limited thereto and may be formed in various configurations or connection types.

FIG. 2 is a block diagram illustrating in detail re-encoding and re-decoding processes performed in the electronic control unit (ECU) 3 and the display board 10 shown in FIG. 1 .

The electronic control unit (ECU) 3 receives the encoded compressed image from the camera 2 and decodes it in the decoder 31 to generate a restored image. Various types of codecs for decoding the encoded image may also be used as in the above-described encoding, but the codec used for encoding must be the same type as the codec used for encoding, so that the image is accurately restored because it conforms to the same standard. The electronic control unit (ECU) 3 re-encodes the reconstructed image in the re-encoder 34 after decoding and other image processing. As a codec for re-encoding the image, it is preferable to use the recently used MPEG4 or H.264/MPEG-4 AVC, HEVC, etc. introduced above, but it is not limited thereto, and various types of codecs may be used. .

The electronic control unit (ECU) 3 may further include a buffer memory 32 or a graphics renderer 33 . If the display panel 20 causes a delay in the display of the image, the frames of the image photographed and transmitted by the camera 2 must wait inside. The buffer memory 32 temporarily stores frame data of the waiting image. When the image is displayed through the display panel 20, the image data corresponding to the next frame is transmitted so that the image can be reproduced naturally. The graphic renderer 33 performs a rendering operation of the image. Rendering is a method of creating a three-dimensional image in consideration of external information such as light source, position, and color so that the two-dimensional image is more realistic and realistic. Rendering methods include wireframe rendering, which draws only the corners of an object, and ray tracing rendering, which determines the color of each pixel by calculating the refraction and reflection of light and tracing the path to the light emitting part. have.

The electronic control unit (ECU) 3 may further include a superimposer (not shown) that performs overlay of a plurality of images to generate a composite image.

The electronic control unit (ECU) 3 outputs the re-encoded compressed image and transmits it to the display board 10 . The display board 10 receives the compressed image data from the electronic control unit (ECU) 3 and re-decodes the re-decoder 101 to generate a restored image, and a resolution and frame rate by processing the restored image. and an image adjusting unit 102 that adjusts (Frame-Rate) or image quality (Bit-Depth).

The re-decoder 101 receives the compressed image re-encoded from the electronic control unit (ECU) 3 and re-decodes the received image to generate a reconstructed image. A codec for re-decoding the re-encoded image may also be of various types as in the above-described re-encoding, but the codec used for re-encoding must be the same type as the codec used for re-encoding, so that the image is accurately restored.

The image adjusting unit 102 processes the reconstructed image and adjusts the resolution, frame-rate, or bit-Depth to adjust brightness, chromaticity, change the saturation, etc. For example, as described above, when receiving a signal from a sensor such as an illuminance sensor 54 in an electronic control unit (ECU) 3 to automatically change the brightness of an image, an electronic control unit (ECU) 3 gives a command to change the image brightness to the display board 10 . In this case, the image adjusting unit 102 may receive a command signal from the electronic control unit (ECU) 3 to adjust the pixel brightness of the image. In addition to the above functions, the display board 10 implements various set contents or controls internal signals. The set contents include contents such as the user's own software update as well as contents of setting the interface to suit the user. In addition, the setting contents of the interface include zoom, resolution, brightness, chromaticity, and saturation of the screen, and include all contents that can be set so that a user's desired image can be output, such as rotation, black and white, style, and view mode. Accordingly, if the user desires, the screen can be enlarged and reduced by zooming in and out of the screen, and the brightness of the screen can also be adjusted. In addition, the view mode may be adjusted so that a portion that is not displayed among the images captured by the camera 2 can be viewed, and the camera 2 may be rotated and moved to allow the user to photograph a desired portion.

3 is a conceptual diagram illustrating a coupling relationship between the display board 10 and the display panel 20 according to an embodiment of the present invention.

As shown in FIG. 3 , the vehicle image display apparatus 1 may be formed in such a way that the display board 10 is coupled to the rear surface of the display panel 20 . By reducing the distance between the display panel 20 and the display board 10 , a data transmission time and a transmission loss rate may be reduced, and the volume of the vehicle image display apparatus 1 may also be reduced. Preferably, the vehicle image display device 1 further includes a frame or a housing (not shown), so that the frame or housing (not shown) can accommodate the combined display panel 20 and the display board 10 . have.

4 is a block diagram showing the entirety of a video monitoring apparatus for a vehicle according to an embodiment of the present invention.

In the vehicle image monitoring apparatus according to an embodiment of the present invention, the vehicle image display apparatus 1 and the camera 2 are each configured in plurality to share the electronic control unit (ECU) 3 . Sharing here means that a plurality of cameras 2 and a plurality of vehicle image display devices 1 are simultaneously connected to one electronic control unit (ECU) 3 to control one electronic control unit (ECU) 3 . means that it is operated by As described above, the electronic control unit (ECU) 3 can decode the image by itself, and if the camera 2 itself is equipped with a function for encoding the image, the electronic control unit (ECU) ) (3), the encoded compressed image is input and undergoes a process of decoding. The electronic control unit (ECU) 3 according to an embodiment of the present invention may independently and simultaneously perform decoding and re-encoding of a plurality of images.

The vehicle image display apparatus 1 may be formed in plurality. According to an embodiment of the present invention, as shown in FIG. 4 , two image display devices 1 and a camera 2 for a vehicle are formed. However, the present invention is not limited thereto, and when the number of cameras 2 is changed, the vehicle image display apparatus 1 may also change in response to the number of cameras 2 . Hereinafter, a case in which there are two image display devices 1 for a vehicle will be described.

According to an embodiment of the present invention, the first and second cameras 2a and 2b are installed one at a time on both side mirrors of the vehicle. In addition, the first vehicle image display device 1a is installed near the driver's seat, and the second vehicle image display device 1b is installed near the passenger seat. The first image photographed from the first camera 2a and the second image photographed from the second camera 2b are encoded and first transmitted to the electronic control unit (ECU) 3 , respectively. The first and second images transmitted to the electronic control unit (ECU) 3 are downsized and downscaled through decoding and other image processing processes. The decoded and restored first and second image data are re-encoded, and then transmitted to the first and second vehicle image display apparatuses 1a and 1b. As described above, the image is displayed through the display panel 20 after each re-decoding process is performed on the display board 10 in the first and second vehicle image display apparatuses 1a and 1b.

It is preferable that the image photographed from the first camera 2a is displayed on the first vehicle image display apparatus 1a, and the image photographed from the second camera 2b is displayed on the second vehicle image display apparatus 1b. . However, the above settings may be arbitrarily changed by the user. That is, the position at which the image is displayed is changed so that the image photographed from the first camera 2a is displayed on the second vehicle image display apparatus 1b, and the image photographed from the second camera 2b is displayed on the first vehicle image display apparatus The setting can be changed to be displayed in (1a). This means that the first and second cameras 2a, 2b and the first and second vehicle image display devices 1a, 1b share one electronic control unit (ECU) 3, and the electronic control unit (ECU) ( This is because the electronic control unit (ECU) 3 controls which vehicle image display device 1 to output the first and second images input to 3).

Alternatively, by dividing the screen in the first vehicle image display device 1a, the setting is such that two images photographed from the first and second cameras 2a and 2b are simultaneously output from the first vehicle image display device 1a. It may be changed. Therefore, if the second vehicle image display device 1b fails, it is automatically detected, a message is displayed on the first display device 1a, and the image obtained from the second camera 2b is used for the first vehicle. Since it can output from the image display device 1a, fail-safety can be guaranteed. In addition, even when a separate camera 2 is additionally installed, the image taken by the separate camera 2 without the need to additionally install the vehicle image display device 1 is displayed on the existing other vehicle image display device 1 . It can also be displayed through

If the vehicle image display device 1 fails, the electronic control unit (ECU) 3 may determine whether there is a failure by first checking whether the power supplied to the display device 1 is abnormal. If the display device 1 fails even though there is no abnormality in the power supply, the electronic control unit (ECU) 3 communicates with the display device 1 periodically and receives a failure occurrence signal to determine whether a failure occurs. have. The electronic control unit (ECU) 3 may check whether the camera 2 is malfunctioning. First, it is possible to determine whether there is a malfunction by checking whether an image signal is continuously input from each camera 2 . If the camera 2 fails even though there is no abnormality in the signal of the image, the electronic control unit (ECU) 3 periodically performs the I2C communication with the camera 2 and receives the failure signal to determine whether the failure occurs. may be

Each of the first and second vehicle image display apparatuses 1a and 1b has content to be set. The set contents include contents such as updating of own software as well as contents of setting the interface to suit the user. In addition, the setting contents of the interface include zoom, resolution, brightness, chromaticity, and saturation of the screen, and include all contents that can be set so that a user's desired image can be output, such as rotation, black and white, style, and view mode. In addition, as described above, it includes the contents of setting whether the first and second images are displayed on which vehicle image display apparatus 1 or whether the screen is divided. In order to control this, each input unit 4 may be formed for each image display device 1 for a vehicle. You can set the contents. The input unit 4 may use a control button module in which a plurality of buttons are formed in one module, but is not limited thereto, and various methods may be used if the contents of the vehicle image display device 1 such as touch and gesture recognition can be set. can If touch is used, the display panel 20 is formed as a touch panel capable of being touched, so that a touch position by a finger or the like can be sensed in a pressure-sensitive or capacitive manner, extracted as location data, and outputted.

The contents of the first and second vehicle image display apparatuses 1a and 1b may be separately set with one input unit 4, but according to an embodiment of the present invention, the first vehicle image display apparatus 1a and the second 2 If the setting contents of the vehicle image display apparatus 1b are the same, by setting only the contents of the first vehicle image display apparatus 1a to which the input unit 4 is connected, the second vehicle image display apparatus 1b can also be set to the same contents have. And even if only the first vehicle image display device 1a updates the software, the second vehicle image display device 1b also updates the software. At this time, the first vehicle image display device 1a, to which the user directly inputs the setting contents, becomes a master, and the second vehicle image display device 1b becomes a slave. The first vehicle image display apparatus 1a selected by the user as the master is generally installed near the driver's seat, but the present invention is not limited thereto and may be changed later to select the second vehicle image display apparatus 1b as the master. Also, if there is no selection of the master, the first and second vehicle image display apparatuses 1a and 1b respectively become masters and receive input separately from the user.

According to an embodiment of the present invention, it is preferable to use an I2C (Inter-Integrated Circuit) method as a method of transmitting the image photographed from the camera 2 to the electronic control unit (ECU) 3 . I2C is one of the low-speed connection methods that connect peripheral devices such as motherboards and embedded systems. Although the speed is slow, it is possible to create a simple configuration and interactive protocol in hardware. The I2C bus consists of a bidirectional open-drain line, Serial Clock (SCL) and Serial Data (SDA), and operates in a Master-Slave type. It has the advantage of being able to connect up to 112 nodes on one bus. However, the present invention is not limited thereto, and various methods may be used as long as the image photographed from the camera 2 can be transmitted to the electronic control unit (ECU) 3 .

The electronic control unit (ECU) 3 is connected to various sensors or systems mounted on the vehicle through network communication 5 . CAN communication is one of in-vehicle network communication (5) technologies, and as described above, the accelerator sensor 51, the brake system 52, the wheel speed sensor 53, the illuminance sensor 54, the lamp control system ( 55) to connect various sensors or systems so that they can communicate with each other. Descriptions of various sensors or systems are omitted since they have been described above. According to an embodiment of the present invention, as the connection method of the network communication 5, it is preferable to use a CAN communication (Controller Area Network), which is mainly used recently, but is not limited thereto and is not limited thereto. : LIN) can use various network methods.

The power of the display may be turned on/off by the user directly through the input unit (not shown), but according to an embodiment of the present invention, the driver's door of the vehicle is opened When the door is opened or a door unlock signal of the vehicle is applied from a distance, the power may be automatically turned on. Conversely, in a state in which the power of the display is turned on, when a door lock signal of the vehicle is applied from a distance, the power may be automatically turned off.

The view mode of the displayed image may change according to the adjustment of the shift lever. The range of the image displayed through the display panel 20 is narrower than the range of the image captured by the camera 2 . Accordingly, a portion of the image captured by the camera that is not displayed may occur. Changing the view mode of the image means that the position of the image displayed within the range of the image captured by the camera 2 is moved and changed so that a portion that has not been displayed can be displayed. When the shift lever is an automatic transmission, when the shift lever is positioned to 'P', 'N', 'D', etc., the view mode of the image displayed through the display panel 20 is upwardly adjusted. Accordingly, the driver can easily drive forward or monitor the rear more easily. However, when the shift lever is positioned to 'R', the view mode of the image displayed through the display panel 20 is adjusted downward. Accordingly, more of the rear bottom portion is displayed, so that the driver can easily drive and park behind. To change the view mode of the image, the shift lever switch 57 detects the position of the shift lever and applies a signal to the electronic control unit (ECU) 3 through the network communication 5 . The electronic control unit (ECU) 3 receiving the signal processes the image by adjusting the range of the displayed image so that the view mode of the image is adjusted upward or downward. As the image whose range is adjusted is displayed through the display panel, the view mode of the image is changed.

Those of ordinary skill in the art to which the present invention pertains will understand that the present invention may be embodied in other specific forms without changing the technical spirit or essential features thereof. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
