Further, the second input / output unit 54B outputs the image data or the like generated by the second calculation unit 50B to the external display image memory 92 or the like.

The second calculation unit 50B includes a second normal image processing unit 60B, a second built-in image processing unit 62B, and a second display output unit 64B. The second normal image processing unit 60B, the second embedded image processing unit 62B, and the second display output unit 64B are realized by executing the program stored in the second storage unit 52B. The program may be supplied from an external device via a communication device (not shown). A part of the program may be composed of hardware (circuit parts).

The second normal image processing unit 60B is activated in a normal case, that is, when the blinker lever 36 is not operated and the lane watch switch 38 is not turned on, and the display liquid crystal display panel 94 is requested by the driver or the like. Display the map image, route image, etc.

The second built-in image processing unit 62B is activated when the blinker lever 36 is operated to the right or when the lane watch switch 38 is turned on, and is from the right camera 34R that images the rear right side of the vehicle 12. The captured image GR is captured and drawn in the display image memory 92. After that, the second display output unit 64B is started.

The second display output unit 64B displays the image data drawn in the display image memory 92 on the display liquid crystal display panel 94. FIG. 1B shows a display form of the display 22 at the time of lane watch. FIG. 1B shows an example in which an image captured from the right camera 34R is displayed on the display 22.

As described above, when the driver's seat 30 is installed on the left side of the vehicle 12, the first driving support device 10A displays the captured image from the left camera 34L on the portion of the meter panel 20 where the tachometer 80 is displayed. Since the image is displayed and the image captured from the right camera 34R is displayed on the display 22 installed in the central portion of the instrument panel 16, the swing angle for checking the following vehicle can be reduced. You can easily check the following vehicle.

Here, the processing operation of the first driving support device 10A will be described with reference to FIG.

First, in step S1, the first embedded image processing unit 62A determines whether or not the lane watch switch 38 is turned on.

When the lane watch switch 38 is turned on, the process proceeds to step S2, and the first built-in image processing unit 62A captures the captured image from the left camera 34L that captures the left rear of the vehicle 12, and is in the meter image memory 42. The captured image is, for example, trimmed and fitted in the drawing area of the tachometer 80.

In step S3, the first display output unit 64A displays the image data drawn in the meter image memory 42 on the meter panel 20. As a result, the image captured from the left camera 34L is displayed in the area of the tachometer 80 on the left side of the meter panel 20, and the speedometer 82 is displayed on the right side.

In step S4, the second embedded image processing unit 62B takes in the captured image from the right camera 34R that captures the right rear side of the vehicle 12 and draws it in the display image memory 92. After that, in step S5, the second display output unit 64B displays the image data drawn in the display image memory 92 on the display 22. As a result, the image captured from the right camera 34R is displayed on the display 22.

On the other hand, if it is determined in step S1 that the lane watch switch 38 is OFF, the process proceeds to step S6, and the first embedded image processing unit 62A determines whether or not the blinker lever 36 has been operated to the left. To do. When the blinker lever is operated to the left, the process proceeds to step S7, and the first built-in image processing unit 62A captures the captured image from the left camera 34L that captures the left rear of the vehicle 12, and is in the meter image memory 42. The captured image is, for example, trimmed and fitted in the display area of the tachometer 80.

In step S8, the first display output unit 64A displays the image data drawn in the meter image memory 42 on the meter panel 20. As a result, the image captured from the left camera 34L is displayed in the area of the tachometer 80 on the left side of the meter panel 20, and the speedometer 82 is displayed on the right side.

After that, in step S9, the second normal image processing unit 60B displays a map image, a route image, or the like requested by the driver or the like on the display 22.

If it is determined in step S6 that the blinker lever has not been operated to the left, the process proceeds to step S10, and the second embedded image processing unit 62B determines whether or not the blinker lever 36 has been operated to the right. To do. When the blinker lever 36 is operated to the right, the process proceeds to step S11, and the second embedded image processing unit 62B captures the captured image from the right camera 34R that captures the right rear of the vehicle 12, and displays the image memory 92. Draw on.

After that, in step S12, the second display output unit 64B displays the image data drawn in the display image memory 92 on the display 22. As a result, the image captured from the right camera 34R is displayed on the display 22.

After that, in step S13, the first normal image processing unit 60A displays the display form of the meter panel 20 at the normal time, that is, the tachometer 80 on the left side of the meter panel 20 and the speedometer 82 on the right side.

If it is determined in step S10 that the blinker lever is not operated to the right, that is, if it is determined that the lane watch switch 38 is OFF and the blinker lever 36 is not operated, in step S14. The first normal image processing unit 60A displays the tachometer 80 on the left side of the meter panel 20 and the speedometer 82 on the right side. Next, in step S15, the second normal image processing unit 60B displays a map image, a route image, or the like requested by the driver or the like on the display 22.

Then, when the process in step S5, the process in step S9, the process in step S13, or the process in step S15 is completed, a predetermined time (for example, 1 / (NTSC frame frequency) or the like) elapses. Later, the process of transition to step S1 is repeated.

As described above, the

bridge portions

18c and 18d of the steering wheel 18 extend in the left-right direction from the shaft portion 18b. Further, the display units (tachometer 80, speedometer 82) that display the rear side of the meter panel 20 in the rear view or the driver's field of view are arranged so as to be offset to the left and right from the shaft portion 18b of the steering wheel 18. It is arranged above the

bridge portions

18c and 18d.

With this arrangement, a suitable display can be performed even while driving. That is, as shown in FIGS. 6A and 6B, as an example, when the driver wants to change the lane to the left side, the driver operates the blinker lever 36 or presses the lane watch switch 38 to the left rear side. Request the display of one. At this time, when displaying the left rear side, the display is performed in the left tachometer 80 in the meter panel 20. As a result, even if the driver starts steering to the left and the steering wheel 18 starts to rotate to the left, the

bridge portions

18c and 18d of the steering wheel 18 move from the right to the center, so that the meter Even if the steering wheel 18 that overlaps with the panel 20 is arranged, it is difficult for the steering wheel 18 to overlap with the display unit that displays the left rear side, and the driver can change lanes with a good view.

In particular, a vehicle in which the steering wheel 18 is arranged on the left side of the vehicle body and on the left side of the driver's seat is often used in a country with right-hand traffic. At the intersection where the steering wheel 18 is arranged, the turning radius when turning left is larger than the turning radius when turning right, and as a result, the steering angle of the steering wheel 18 is smaller when turning left than when turning right.

In this case, even if the left rear side is displayed in the left side region of the meter panel 20 (inside the left tachometer 80), the steering wheel 18 has a small steering angle, so that the

bridge portions

18c and 18d are unlikely to overlap the left side region. .. On the other hand, when the steering wheel 18 is turned to the right with a large steering angle, if the display is performed in the meter panel 20, there is a high possibility that the

bridge portions

18c and 18d overlap with the meter panel 20, so that the rear right It is preferable to display the side display on the display 22 instead of in the meter panel 20.

At the same time, the speed display and the like are displayed on the right side of the meter panel 20 to maintain a state in which confirmation is possible. In the present embodiment, since information such as the speed of the meter panel 20 can be confirmed in both fields of view, and important information such as the speed can always be secured without changing the position in the meter panel 20, the driver. However, it is possible to shorten the time for grasping the display position each time the vehicle is steered and reduce the angle such as swinging.

When the steering wheel 18 is arranged in the right seat, the display on the right rear side is displayed on the right side of the meter panel 20, and the speed system or the like is displayed on the left side of the meter panel 20, or the tachometer 80 is displayed. The same effect can be obtained by digitally displaying the speed between the speedometers 82 and displaying the left rear side on the display 22 at the center of the vehicle body.

Next, the in-vehicle driving support device (hereinafter referred to as the second driving support device 10B) according to the second embodiment will be described with reference to FIGS. 6A to 11.

The second driving support device 10B has almost the same configuration as the first driving support device 10A described above, but is different in that it has a BSI (blind spot information) function. In general, when another vehicle is diagonally behind the vehicle 12 while the vehicle 12 is running, the BSI function turns on the indicator in the door mirror in that direction as shown in FIGS. 6A to 7B, and the other vehicle approaches. Inform you that you are. In this situation, when the blinker lever 36 is operated in the direction in which the indicator 100 is lit, the driver is alerted by the blinking of the indicator 100 and the alarm sound.

Then, the second driving support device 10B displays the symbol image 102 imitating the indicator 100 as an captured image, that is, an image captured from the left camera 34L incorporated in place of the tacometer 80, or a right side displayed on the display 22. The image captured from the camera 34R is superimposed and displayed. In the description of the second operation support device 10B, the same names and reference numerals are used for the processing units corresponding to the various processing units constituting the first operation support device 10A, and the duplicate description thereof will be omitted.

As shown in FIG. 8, the meter panel 20 of the second operation support device 10B includes a meter ECU 40, a meter image memory 42, a meter liquid crystal display panel 44, a first sound source 46A, and a first speaker 48A.

The first calculation unit 50A has a first normal image processing unit, a first built-in image processing unit, and a first display output unit, similarly to the first operation support device 10A described above, and in particular, a second operation. The support device 10B further includes a first audio output unit 65A. The first audio output unit 65A is activated by the first embedded image processing unit 62A, reads audio data from the first sound source 46A, and outputs the audio data to the first speaker 48A. As a result, a warning sound is output from the first speaker 48A.

Further, as shown in FIGS. 8 and 9, the second driving support device 10B is installed on the left side of the vehicle 12 and searches for the left side of the vehicle 12 with the left radar 110L (see FIG. 8) and the vehicle. It is installed on the right side of the vehicle 12 and has a right-side radar 110R (see FIG. 9) for searching the right side of the vehicle 12. Further, the second driving support device 10B has a left peripheral monitoring unit 112L (see FIG. 8) and a right peripheral monitoring unit 112R (see FIG. 9).

As shown in FIG. 8, the left peripheral monitoring unit 112L detects whether or not another vehicle is approaching the left side of the vehicle 12 within a predetermined distance based on the left detection signal SfL from the left radar 110L. When another vehicle is approaching the left side of the vehicle 12 within a predetermined distance, the left peripheral monitoring unit 112L transmits the BSI detection result, that is, the left side detection signal SfR, for example, via CAN (Control Area Network) to the meter ECU 40. Output to. The right side radar 110R and the right side peripheral monitoring unit 112R shown in FIG. 9 will be described later.

As shown in FIG. 8, the first built-in image processing unit 62A of the meter ECU 40 trims and fits the captured image of the left camera 34L into the display area of the tacometer 80 in the meter image memory 42, and fits the captured image. For example, a symbol image 102 imitating the indicator 100 based on the BSI detection result is drawn on the upper part of the above. After that, the first built-in image processing unit 62A activates the first display output unit 64A and the first audio output unit 65A, so that the image data drawn in the meter image memory 42 is displayed on the meter panel 20 and the first A warning sound is output from the speaker 48A.

That is, as shown in FIGS. 6B and 7B, the captured image from the left camera 34L is displayed in the area of the tachometer 80 on the left side of the meter panel 20, and the indicator 100 is imitated on, for example, the upper part of the captured image. The symbol image 102 is displayed. Along with the display of the symbol image 102, a warning sound is output as a voice from the first speaker 48A.

On the other hand, as shown in FIG. 9, the display 22 of the second driving support device 10B has a display ECU 90, a display image memory 92, a display liquid crystal display panel 94, a second sound source 46B, and a second speaker 48B. ..

The right side peripheral monitoring unit 112R detects whether or not another vehicle is approaching the right side of the vehicle 12 within a predetermined distance based on the right side detection signal SfR from the right side radar 110R. When another vehicle is approaching the right side of the vehicle 12 within a predetermined distance, the right side peripheral monitoring unit 112R transmits the BSI detection result, that is, the right side detection signal SfR to the second embedded image processing unit 62B via, for example, CAN. Output to.

The second built-in image processing unit 62B of the display ECU captures the captured image from the right camera 34R and draws it in the display image memory 92, and at the same time, a symbol image imitating the indicator 100 is placed on the upper portion of the drawn captured image, for example. 102 is drawn. After that, the second built-in image processing unit 62B activates the second display output unit 64B and the second audio output unit 65B, so that the image data drawn in the display image memory 92 is displayed on the display 22 and the second A warning sound is output from the speaker 48B.
