Description

  The present invention relates to a display control device that controls display on a monitor.

  As a conventional display control device, a device that compensates a driver's blind spot area in front of a vehicle by displaying an image taken by a camera device provided on a mirror case of a vehicle door mirror on a display is known. (For example, refer to Patent Document 1).

JP 2000-272418 A (page 3-4, FIG. 3)

  However, the conventional display control device has a problem that the driver's blind spot area in front of the vehicle cannot be compensated when an obstacle is present in front of the camera device.

  The present invention has been made to solve the conventional problems, and an object of the present invention is to provide a display control device that can more appropriately compensate for the driver's blind spot area in front of the vehicle.

  The display control device of the present invention uses the data corresponding to the presence / absence of an obstacle in the front right of the vehicle and the data corresponding to the presence / absence of the obstacle in the left front of the vehicle, so long as there is an obstacle in the right front of the vehicle. It has a configuration including control means for displaying a left front image of the vehicle on a monitor and displaying an image of the right front side of the vehicle on the monitor if there is an obstacle on the left front side of the vehicle.

  With this configuration, the display control apparatus of the present invention displays an image of the left front of the vehicle on the monitor if there is an obstacle on the right front of the vehicle, and displays the front right of the vehicle if there is an obstacle on the left front of the vehicle. Since the above image is displayed on the monitor, the driver's blind spot area with respect to the front of the vehicle can be more appropriately compensated than before. Note that “data corresponding to the presence or absence of an obstacle” is data for identifying the existence or non-existence of an obstacle to a computer, and is only for one of the cases where an obstacle exists and the case where no obstacle exists. It is a concept that includes data that is output and data is not output in the other case. Further, the “data corresponding to the presence / absence of an obstacle on the right front side of the vehicle” and the “data corresponding to the presence / absence of an obstacle on the left front side of the vehicle” may be output by different sensors or the same sensor. It may be output. As a case where output is performed by the same sensor, a case where a sensor provided at the front center portion of the vehicle and whose detection surface rotates is considered. The “front left image of the vehicle” and the “right front image of the vehicle” may be output by a camera provided on the left side of the vehicle and a camera provided on the right side of the vehicle, respectively, or the same camera. What was divided | segmented what was output by (3) may be sufficient.

  Further, the control means of the display control device of the present invention uses the data corresponding to the presence or absence of traffic jam to monitor the left front image of the vehicle when traffic jam occurs and there is an obstacle on the right front side of the vehicle. If a traffic jam occurs and there is an obstacle on the left front of the vehicle, an image on the right front of the vehicle is displayed on the monitor.

  With this configuration, since the display control device of the present invention automatically starts selecting a video when the vehicle is in a traffic jam, the driver's blind spot area with respect to the front of the vehicle may increase due to the vehicle ahead. The driver's blind spot area with respect to the front of the vehicle can be appropriately compensated for during high traffic congestion. The “data corresponding to the presence / absence of traffic jam” is data for identifying the presence / absence of traffic jam to the computer, such as data provided on the infrastructure side such as VICS (Vehicle Information and Communication System) data, It includes data calculated from navigation data etc. in its own device.

  In addition, the display control device of the present invention uses the data corresponding to the presence / absence of a curve in the right front of the vehicle and the data corresponding to the presence / absence of the curve in the left front of the vehicle, so long as the vehicle exists in the right front of the vehicle. The control unit is configured to display a right front image on the monitor and display a left front image of the vehicle on the monitor if a curve exists on the left front side of the vehicle.

  With this configuration, the display control device of the present invention displays an image of the right front of the vehicle on the monitor if there is a curve on the right front of the vehicle, and an image of the left front of the vehicle if there is a curve on the left front of the vehicle. Is displayed on the monitor, so that the driver's blind spot area with respect to the front of the vehicle can be more appropriately compensated than before. Note that “data corresponding to the presence / absence of a curve” is data for allowing the computer to identify the presence / absence of a curve, and data is output only in one of the cases where a curve exists and when no curve exists. This is a concept including the case where data is not output in the other case.

  Further, the control means of the display control device of the present invention uses the data corresponding to the presence / absence of traffic jam to display an image of the vehicle right front on the monitor when traffic jam occurs and a curve exists in the vehicle right front. If a traffic jam occurs and there is a curve on the left front side of the vehicle, an image on the left front side of the vehicle is displayed on the monitor.

  With this configuration, since the display control device of the present invention automatically starts selecting a video when the vehicle is in a traffic jam, the driver's blind spot area with respect to the front of the vehicle may increase due to the vehicle ahead. The driver's blind spot area with respect to the front of the vehicle can be appropriately compensated for during high traffic congestion.

  The present invention can provide a display control device capable of appropriately supplementing the driver's blind spot area with respect to the front of the vehicle.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
First, the configuration of the driving support system according to the first embodiment will be described.

  As shown in FIGS. 1 and 2, the driving support system 10 according to the present embodiment includes a left front obstacle sensor 11 a that is mounted on the left front side of the vehicle 90 and detects an obstacle ahead of the vehicle 90, and the vehicle 90. A front right obstacle sensor 11b that detects an obstacle ahead of the vehicle 90 and mounted on the left side mirror 91a of the vehicle 90. A left camera 12a that captures a "front image", a right camera 12b that is mounted in a side mirror 91b on the right side of the vehicle 90 and that captures a front image of the vehicle 90, that is, a "right front image of the vehicle 90", and a vehicle 90 A display 13 as a monitor for displaying an image mounted on an instrument panel (not shown) inside the vehicle, and a GP mounted on a vehicle 90 for receiving a current position according to latitude and longitude (Global Positioning System) receiver 14, FM (Frequency Modulation) receiver 15 that is mounted on vehicle 90 and receives and decodes VICS information, and control that is mounted on vehicle 90 and controls the entire driving support system 10. Device 16.

  Here, as the left front obstacle sensor 11a and the right front obstacle sensor 11b, for example, a sensor using a sonar or UWB (Ultra Wide Band) may be used.

  The control device 16 includes a ROM (Read Only Memory) 16a that stores various control programs, a CPU (Central Processing Unit) 16b that implements various functions by executing the various control programs stored in the ROM 16a, and a CPU 16b. And a RAM (Random Access Memory) 16c for storing various processing results. The control device 16 controls the display on the display 13 and constitutes a display control device.

  Next, the operation of the driving support system 10 will be described.

  As shown in FIG. 3, the CPU 16 b stores the current position received by the GPS receiver 14 in the RAM 16 c (S 31), and based on the VICS information received and decoded by the FM receiver 15, traffic congestion information, that is, “congestion” The data corresponding to the presence or absence of "is stored in the RAM 16c (S32).

  Next, the CPU 16b determines whether or not the vehicle 90 is in a traffic jam based on the current position stored in the RAM 16c in S31 and the traffic jam information stored in the RAM 16c in S32 (S33).

  When it is determined in S33 that the vehicle 90 is not in a traffic jam, the CPU 16b once ends the series of processes shown in FIG. 3 and starts the series of processes shown in FIG. 3 again.

  On the other hand, when it is determined in S33 that the vehicle 90 is in a traffic jam, the CPU 16b takes an image of the front of the vehicle 90 with the left camera 12a and the right camera 12b and stores it in the RAM 16c (S34).

  Next, the CPU 16b detects the detection result by the left front obstacle sensor 11a, that is, “data corresponding to the presence or absence of an obstacle in the front left of the vehicle 90” and the detection result by the right front obstacle sensor 11b, that is, “in the right front of the vehicle 90”. The position of the obstacle ahead of the vehicle 90 relative to the vehicle 90 is detected based on the “data corresponding to the presence or absence of the obstacle”, and the detected position of the obstacle is stored in the RAM 16c (S35).

  Next, based on the position of the obstacle stored in the RAM 16c in S35, the CPU 16b sets the vehicle on the opposite side of the left camera 12a and the right camera 12b on the left and right sides of the vehicle 90 from the side on which the obstacle is approaching. The video taken by the person arranged at 90 is selected from the video stored in the RAM 16c in S34 (S36), and the video selected in S36 is displayed on the display 13 (S37). Therefore, for example, as shown in FIG. 4A, the CPU 16b displays an image taken by the right camera 12b when the vehicle 100 as an obstacle ahead of the vehicle 90 is on the left side of the vehicle 90. When the vehicle 100 as an obstacle ahead of the vehicle 90 is approaching the right side of the vehicle 90 as shown in FIG. 4B, an image taken by the left camera 12a is displayed. 13 is displayed. As described above, the ROM 16a, the CPU 16b, and the RAM 16c are photographed by the left camera 12a and the right camera 12b that are arranged on the vehicle 90 on the left side and the right side of the vehicle 90 on the side opposite to the side on which the obstacle is approaching. The control means which selects the image | video produced based on the detection result by the left front obstacle sensor 11a and the right front obstacle sensor 11b is comprised.

  Note that when the video is displayed on the display 13 in S37, the CPU 16b once ends the series of processes shown in FIG. 3 and starts the series of processes shown in FIG. 3 again.

  As described above, the control device 16 causes the display 13 to display an image taken by the right camera 12b when an obstacle ahead of the vehicle 90 is approaching the left side of the vehicle 90, and Since an image taken by the left camera 12a is displayed on the display 13 when an obstacle is on the right side of the vehicle 90, the blind spot area of the driver with respect to the front of the vehicle 90 can be more appropriately compensated than before.

  In addition, since the CPU 16b automatically starts the video selection when the vehicle 90 is in a traffic jam, the driver's blind spot area with respect to the front of the vehicle 90 is likely to increase due to the vehicle ahead. The driver's blind spot area with respect to the front of the vehicle 90 can be appropriately compensated for in a traffic jam. In addition, the control apparatus 16 may start selection of a video triggered by conditions other than when the vehicle 90 is in a traffic jam. For example, the control device 16 may start selecting a video in response to a user's manual operation.

  Further, since the control device 16 does not simultaneously display the video image taken by the left camera 12a and the video image taken by the right camera 12b on the display 13, the screen 13a of the display 13 is small as shown in FIG. 5, for example. In this case, both the navigation video 13b of the vehicle 90 (see FIG. 2) and the video 13c taken by the left camera 12a (see FIG. 2) or the right camera 12b (see FIG. 2) are displayed on the screen 13a. Even when displaying, the video 13c can be displayed relatively large and clearly. 5 is an image taken by the left camera 12a when the vehicle 100 (see FIG. 4) in front of the vehicle 90 is a large bus that approaches the right side of the vehicle 90.

  Moreover, if the driving support system 10 is applied to the vehicle 90 in which the left camera 12a is already mounted in the side mirror 91a and the right camera 12b is already mounted in the side mirror 91b, the driving support system 10 can reduce the cost for realizing it. be able to. The place where the left camera 12a is installed may be a place other than the side mirror 91a as long as it is on the left side of the vehicle 90. Similarly, as long as the right camera 12b is installed on the right side of the vehicle 90, the right camera 12b may be located outside the side mirror 91b.

  The control device 16 realizes various functions by various control programs stored in the ROM 16a. However, the control device 16 may realize various functions only by hardware without using software. .

  Further, the control device 16 temporarily stores the video taken by the left camera 12a and the video taken by the right camera 12b in the RAM 16c, and then selects the video on the RAM 16c, thereby displaying the video on the display 13. However, the video to be displayed on the display 13 may be selected by other methods. For example, the control device 16 selects an image to be displayed on the display 13 by being electrically connected to only one of the left camera 12a and the right camera 12b that has taken the image to be displayed on the display 13. Also good.

(Second Embodiment)
First, the configuration of the driving support system according to the second embodiment will be described.

  In addition, about the structure similar to the structure of the driving assistance system 10 (refer FIG. 1) which concerns on 1st Embodiment among the structures of the driving assistance system which concerns on this Embodiment, it is the structure of the driving assistance system 10 and The same reference numerals are assigned and detailed description is omitted.

  As shown in FIG. 6, the configuration of the driving support system 50 according to the present embodiment includes a gyro 51 that is mounted on the vehicle 90 and detects the direction of the vehicle 90, and detects the speed of the vehicle 90 that is mounted on the vehicle 90. Vehicle speed sensor 52, a large capacity storage device 53 such as an HDD (Hard Disk Drive) that is mounted on the vehicle 90 and stores map information, and a control device that is mounted on the vehicle 90 and controls the entire driving support system 50. 54 is the same as the configuration provided in the driving support system 10 instead of the control device 16 (see FIG. 1).

  Here, the configuration of the control device 54 is the same as the configuration provided in the control device 16 in place of the ROM 54a storing various control programs in place of the ROM 16a (see FIG. 1). The control device 54 controls the display on the display 13 in the same manner as the control device 16, and constitutes a display control device.

  Next, the operation of the driving support system 50 will be described.

  As shown in FIG. 7, the CPU 16b executes the processes of S71, S72, S73, and S74 in the same manner as S31, S32, S33, and S34 (see FIG. 3).

  Next, the CPU 16b acquires the road shape around the vehicle 90 based on the map information stored in the mass storage device 53 and the current position stored in the RAM 16c in S71, and stores the acquired road shape in the RAM 16c. (S75).

  Next, the CPU 16b stores the direction of the vehicle 90 detected by the gyro 51 and the speed of the vehicle 90 detected by the vehicle speed sensor 52 in the RAM 16c (S76).

  Then, the CPU 16b is proceeding along the curve based on the current position stored in the RAM 16c in S71, the road shape stored in the RAM 16c in S75, and the direction and speed of the vehicle 90 stored in the RAM 16c in S76. It is determined whether or not there is (S77). The determination result in S77 constitutes “data corresponding to the presence / absence of a curve”.

  When determining in S77 that the vehicle 90 is not traveling on the curve, the CPU 16b executes the processes of S78, S79, and S80 similarly to S35, S36, and S37 (see FIG. 3).

  On the other hand, if the CPU 16b determines in S77 that the vehicle 90 is moving along the curve, the image taken by the one closer to the inside of the curve of the left camera 12a and the right camera 12b is taken from the image stored in the RAM 16c in S74. The image selected in S81 is displayed on the display 13 (S80). Therefore, for example, as shown in FIG. 8A, the CPU 16b causes the display 13 to display an image taken by the right camera 12b when the vehicle 90 is traveling on the right curve 110a, as shown in FIG. As shown in b), when the vehicle 90 is traveling on the left curve 110b, an image taken by the left camera 12a is displayed on the display 13. As described above, the ROM 54a, the CPU 16b, and the RAM 16c constitute control means for selecting an image taken by the one closer to the inside of the curve when the vehicle 90 is on the curve, of the left camera 12a and the right camera 12b. .

  Note that when the video is displayed on the display 13 in S80, the CPU 16b once ends the series of processes shown in FIG. 7 and starts the series of processes shown in FIG. 7 again.

  As described above, the control device 16 causes the display 13 to display an image taken by the right camera 12b when the vehicle 90 is on the right curve, and the left camera 12a when the vehicle 90 is on the left curve. Therefore, the blind spot area of the driver with respect to the front of the vehicle 90 can be more appropriately compensated than in the prior art.

  As described above, the display control device according to the present invention has an effect that the driver's blind spot area with respect to the front of the vehicle can be more appropriately compensated than before, and the vehicle with respect to the front of the vehicle when the vehicle is in a traffic jam. This is useful as a display control device that compensates for the driver's blind spot area.
