It is also possible to select which mode to select.

Hereinafter, a control process of the vehicle image indoor display apparatus 10 according to the embodiment will be described with reference to the drawings.

As shown in FIG. 7, the method for controlling a vehicle image indoor display apparatus according to the present invention includes a providing step S10, a mode input step S20, a mode selection step S30, and a mode execution step S40. However, the providing step (S10) is to provide a vehicle image indoor display device 10 of the present invention described above, the description thereof will be replaced as described above. Thereafter, the control flow proceeds to the mode input step S20, in which an input signal from the mode selection switch 300 selected by the driver is transmitted to the controller 400, and the controller 400 transmits the mode selection switch. A mode selection step S30 of selecting a predetermined operation mode based on the selection mode signal from the 300 and the mode data preset and stored in the storage unit 500 is executed. Here, the mode data refers to a preset reference value for determining whether the mode selected by the driver is an external image mode, a mood mode, or a simple display mode with respect to the selection mode signal transmitted as an electrical signal. That is, as shown in FIG. 8, the selection mode signal is compared with the mode data (first / second mode data) preset and stored in the storage unit 500 (S31). Then, when it is determined in step S31 that the selection mode signal and the first mode data are the same, the controller 400 determines that the operation mode selected by the driver is the external image mode (S33). On the other hand, when the controller 400 determines that the selection mode signal and the first mode data are not the same in step S31, the control flow is switched to step S35 to compare the selection mode signal with the second mode data (S35). When the selection mode signal is the same as the second mode data in step S35, the controller 400 determines that the operation mode selected by the driver is the mood mode (S37), and when the selection mode signal is not the same as the second mode data. The controller 400 determines that the operation mode selected by the driver is a simple display mode (S39).

Thereafter, the control unit 400 executes a mode execution step S40 of transmitting a predetermined operation control signal according to the selected operation mode to the display unit 700 to display an image. When the operation mode is the mood mode, the controller 400 may change the lighting atmosphere of the vehicle interior by outputting light of a predetermined color and illuminance to the storage unit 500.

In addition, when the operation mode is the simple display mode, the on / off state of the external image is determined through the switching of the on / off state by the simple operation of the driver. In the off state, the display of the external image is turned off by stopping the display of the external image. Such on / off switching is performed through the repetitive operation of the mode selection switch for the simple display mode in the present embodiment. In some cases, a separate input switch for the simple display mode may be further provided. Various modifications are possible depending on the specification.

On the other hand, when the operation mode is the external image mode, the control unit 400 executes a mode execution step for executing the external image mode, as shown in FIG. 9, in the external image mode, the sensing step (S410) and the sub mode. A determination step S420 and a sub mode operation step S430 are included. First, the controller 400 executes a sensing step S410 for causing the sensing unit 200 to detect vehicle driving environment information. In the detecting step (S410), the vehicle speed sensor 230, the vehicle shift detection sensor 240, and the steering angle sensor 250 of the detector 200 are respectively the vehicle driving speed and the vehicle driving shift information, that is, the shift range and the vehicle. The steering angle of the steering wheel is sensed and transmitted to the controller 400.

Thereafter, the controller 400 executes the determination step based on the detected vehicle driving environment information and data preset in the storage 400 (S420). As shown in FIG. 10, the sub-mode determination step S420 includes a standby mode, a parking image mode, a low speed image mode, a high speed image mode, and a lane change mode that are executed by the controller 400 based on the vehicle driving environment information. Any one of the sub modes may be determined and selected. The standby image mode indicates an external image mode that forms a standby state of the display of the display unit while the vehicle is parked, and the parking image mode indicates that the driver wants to park the vehicle. The low speed image mode indicates an external image mode executed when the vehicle is traveling at low speed, and the high speed image mode indicates an external image mode executed when the vehicle is driving at high speed, The change mode is used when a lane change occurs simultaneously with the high speed driving of the vehicle. Indicates the external picture mode to be executed.

First, the controller 400 executes the parking range determination step S4210 of determining whether the vehicle driving shift information, that is, the shift range is the parking range P indicating the parking state, in step S4210, and determines the parking range determination step S4210. If the control unit 400 determines that the currently detected shift range is the parking range P, the control flow proceeds to step S4211. That is, when the control unit 400 determines that the currently detected shift range TR is the same as the parking range P in the parking range determination step S4210, the control unit 400 determines that the sub mode to be executed is the standby mode. The judgment is set (S4211). The standby mode determines that the driver is in the stage of forming or maintaining the parking state or before the initial driving, and forms the display off state or forms the display on state for a preset time of about 10 seconds to display the external image. Afterwards, an off state of the display may be formed, such as to form a display off state, thereby eliminating unnecessary external image display.

On the other hand, when the controller 400 determines that the currently detected shift range is not the same as the parking range P in step S4210, the control flow proceeds to step S4220. That is, the sub-mode determination step S420 includes a parking driving determination step S4220. The control unit 400 determines that the shift range currently detected by the control unit 400 is not the same as the parking range P in step S4220. In operation S4220, the vehicle driving speed V detected by the vehicle speed sensor 230 may be compared with the preset parking driving speed Vp preset and stored in the storage 500. The preset parking driving speed Vp is a speed of about 3 to 5 km / h, which is used to determine the case where the driver forms the D and R ranges and forms the front and rear driving conditions to park the vehicle at the parking position (not shown). The reference value of the vehicle speed is shown, and the speed value may vary depending on the design specification.

When the controller 400 determines that the current vehicle speed V is equal to or less than the preset parking driving speed Vp in the parking driving determination step S4220, the control flow proceeds to step S4221. That is, when the current vehicle speed V is less than or equal to the preset parking driving speed Vp in the parking driving determination step S4220, the controller 400 determines that the driver performs the front and rear driving operation for parking the vehicle. The sub mode to be executed is set to the parking video mode.

On the other hand, when the controller 400 determines that the current vehicle speed V is greater than the preset parking driving speed Vp in step S4220, the control flow proceeds to step S4230. That is, the sub-mode determination step S420 includes a low-speed driving determination step S4230. In the low-speed driving determination step S4230, the controller 400 is preset in the current vehicle speed V and the storage 500. The stored preset low speed traveling speed Vs is compared (S4230). The predetermined low speed traveling speed (Vs) may be set in various values according to the design specification. In this embodiment, the speed is about 30-40 km / h, and the driver may form a low speed driving state in an area such as a back road. The reference value of the vehicle speed for judgment is shown. When the control unit 400 determines that the current vehicle speed V is less than or equal to the preset low driving speed Vs in the low speed driving determination step S4230, the control unit 400 moves forward for the driver to drive the vehicle at low speed. In operation S4231, it is determined that the driving operation is performed, and the sub mode to be executed is set to the low speed traveling image mode.

On the other hand, when the controller 400 determines that the current vehicle speed V is greater than the preset low speed traveling speed Vs in step S4230, the control flow proceeds to step S4240. That is, the sub-mode determination step (S420) includes a steering angle determination step (S4240), and in the steering angle determination step (S4240), the control unit 400 detects a current steering angle detected by the steering angle sensor 250 of the detection unit 200 ( θ) is compared to the preset steering angle θs which is preset and stored in the storage unit 500 (S4240). The preset steering angle [theta] s is a value in which various values can be set according to the design specification. In this embodiment, the preset steering angle [theta] s represents a reference value for determining whether the driver wants to make a lane change during high-speed driving. In the steering angle determination step (S4240), when the controller 400 determines that the current steering angle θ is less than or equal to the preset steering angle θ s, the controller 400 determines a current situation in which the driver advances the vehicle in a simple forward high speed manner. It is determined that the operation is made and the sub mode to be executed is set to the high speed image mode (S4241). On the other hand, when the control unit 400 determines that the current steering angle θ is greater than the preset steering angle θs in step S4240, the control flow is transferred to step S4243, and the sub mode of the external image mode to be executed is set to the lane changing mode. do. That is, the controller 400 determines that the driver wants to change lanes at the same time as the high speed driving, and sets the sub mode to the lane change mode.

On the other hand, the method for controlling a vehicle image indoor display apparatus of the present invention may further include the following steps when the sub mode is the parking image mode. That is, when the control unit 400 sets the sub mode to the parking image mode in step S4221, the control flow starts to switch to step S4222, and as shown in FIG. 11, step S4222 determines the backward range determination step S4223. Include. In the reverse range determination step S4223, the controller 400 determines whether the currently detected shift range is the reverse range R. FIG. When the controller 400 determines that the currently detected shift range is the reverse range R, the controller 400 determines that the driver is currently driving backward while the vehicle is parked, and displays the FR / FL display 710FR / FL. The front and rear image switching step (S4225) is performed to display the rear image. In other words, by switching the front and rear images so that the external image signal for the rear region can be output on the display side of the region corresponding to the A-pillar, it is possible to output a stable rear view even if the driver does not look backward while turning his head during the backward driving operation. An area image can be secured. The rear region image may utilize image information acquired through the RR / RL image input unit 100RR, RL, or in some cases, may use an image acquired from a rear dedicated camera (not shown) disposed in a vehicle trunk lid. Many variations are possible depending on design specifications.

In addition, when the vehicle image indoor display apparatus 10 of the present invention includes the ultrasonic sensing unit 210 and / or the laser sensing unit 220 to measure the presence or distance of an external object, that is, an obstacle, The control method of the vehicle image indoor display apparatus 10 of the present invention may further include an additional control step. That is, when it is determined in step S4243 that the sub-mode in which the controller 400 should be executed is the lane change mode, the control flow proceeds to step S4250. As shown in FIG. 12, step S4250 may include an input detection step S4251, an obstacle detection determination step S4253, and a guide display step S4255. First, in step S4251, the controller 400 receives a signal from the ultrasonic detector 210 and / or the laser detector 220 of the detector 200 in the input detection step S4251. The controller 400 determines whether the presence of an external object or an obstacle is detected by the ultrasonic detector 210 and / or the laser detector 220 based on the input signal and data previously stored in the storage 500. The obstacle detection determination step S4253 is executed. When the controller 400 outputs a changed signal value more than a predetermined value from the ultrasonic detector 210 and / or the laser detector 220 in the obstacle detection determination step S4253, the controller 400 may detect the ultrasonic detector 210. And / or the laser detector 220 detects an external object / obstacle, and switches the image background screen to a display corresponding to the corresponding area where the obstacle is detected, or displays a guide message such as a warning message or an icon. A guide display step is performed (S4253). In addition, a separate sound output unit 800 (see FIG. 2) may be further provided to implement a sound warning on the side of the region where the obstacle is detected. On the other hand, when the controller 400 determines that the obstacle is not detected in step S4253, the control flow proceeds to the sub mode operation step S430 for executing the corresponding sub mode without a separate indication.

After the sub mode determination step S420 is completed, the controller 400 executes the sub mode operation step S430 for executing an operation operation corresponding to the selected sub mode. For example, in the present embodiment, when the corresponding sub mode is set to the standby mode, the controller 400 turns off the screen display of the display. In some cases, as described above, an external image may be displayed for only about 5 to 10 seconds and then switched to the image display off state. When the sub mode is the parking image mode, the display normally displays all images of the corresponding blind spots, but as described above, when the shift range is the reverse range R, the display may execute a function of switching the front and rear images. Through the front and rear screen switching as described above, the driver may turn his / her head, thereby significantly reducing the risk of an accident that may occur when operating the steering wheel. When the sub mode is the low speed image mode, the mode image for the blind spot is normally displayed, but when the sub mode is the high speed image mode, the mode is switched off without displaying the image for the blind spot of the driver on the display. This is to prevent the driver's obstruction of attention in high speed driving. On the other hand, when the sub-mode is the lane change mode, the display can be switched on in the direction in which the driver wants to steer to determine whether other vehicles or obstacles are present in the blind spot. The display opposite to the desired direction may display an image of the rear blind spot in the direction to be steered to increase the driver's side attention. For example, when the driver wants to steer to the left at high speed, the FR display 710FR forms an on state to display an image of the front blind area to remove the blind spot of the driver, and the FL display 710FL is at the rear side. Display the image acquired by the RR image input unit 100RR corresponding to the ARR region to facilitate image acquisition of the blind spot and the rear of the direction to be steered to achieve a safe steering operation for the driver to form a stable driving state. Can be achieved.

As described above, the vehicle image indoor display device and the control method thereof according to the present invention removes the blind spot of the driver to achieve safe driving and at the same time enables the mood light operation to be executed by selection to increase driving comfort. This can improve passenger satisfaction. In addition, the display of the present invention may be implemented in various types to take a configuration to prevent the driver's attention deterioration, and in the case of the parking image mode may further include a function for displaying a detection function of the obstacle around, such as to achieve a variety of modifications As such, the present invention is capable of various configurations inducing various changes in addition to the above configurations.
