As a result, it can be provided relatively easily and can be visually recognized in the same manner as a conventional rearview mirror, so that it is easy for the driver to visually recognize and does not give a sense of discomfort.

[0008]

[Embodiment of the invention]

 Hereinafter, a configuration of the present invention will be described in detail based on an embodiment illustrated in the accompanying drawings.

FIG. 1 shows an entire vehicle to which a vehicle rear view device according to the present invention is applied. This rear visual recognition device is provided on the left and right diagonal rear sensors 3 and 4 provided on the left and right door mirrors 1 and 2 to image the diagonal rear of the vehicle body, and on the rear end of the roof 5 to image the rear of the vehicle body. Based on signals from the vehicle body rear sensor 6, the vehicle body rear sensor 8 provided at the rear end of the trunk portion 7 so as to capture the image just behind the vehicle body, and signals from these four sensors 3/4. It comprises a display 9 provided centrally for display on the inside of the vehicle at the front end of the roof 5, and a control unit 10 for controlling the sensors 3, 4, 6 and 8 and the display 9. As shown in FIG. 3 as well, the display 9 is provided in the center of the vehicle width direction at the front end of the roof 5 where the conventional rearview mirror is provided, instead of the rearview mirror.

Each sensor 3, 4, 6, 8 is connected to the control unit 10 by a conductive cable 11, 12, 13, 14, respectively, and an image pickup signal from the sensor 3, 4, 6, 8 is controlled by the control unit. It is designed to be input to 10. The control unit 10 and the display 9 are connected by a conductive cable 15, and the video signal from the control unit 10 is transmitted to the display 9. The conductive cables 11 to 15 may be optical fiber cables.

The left and right diagonal rear sensors 3 and 4 are arranged so as to obtain a diagonally rearward image of the vehicle body that is substantially similar to the reflection images of the left and right door mirrors 1 and 2. Further, the rear sensor 6 is arranged in the center portion in the vehicle width direction so that an image of the rear of the vehicle body that is substantially the same as the reflection image of the conventional rearview mirror can be obtained. On the other hand, the vehicle body rear sensor 8 is capable of capturing an image at a wider angle than the rear sensor 6, and as shown in FIG. 2, it is provided slightly downward so that the left and right door mirrors 1 and 2 and the conventional room. It is designed to image the rear of the vehicle body, which is the blind spot of the mirror. An image pickup device such as a high-sensitivity CCD image pickup device is desirable for these sensors 3, 4, 6, and 8.

The display 9 is composed of a liquid crystal panel and, as shown in FIG. 3, is divided into four sections so that the images picked up by the sensors 3, 4, 6, and 8 are individually displayed. That is, the left and right diagonal rear display sections 21 and 22 that display the diagonal rear images captured by the left and right diagonal rear sensors 3 and 4 are sandwiched between the left and right diagonal rear display sections 21. A rear display unit 23 that displays a rear image captured by the rear sensor 6 above the middle portion of the direction, and a vehicle body that displays a rear image captured by the vehicle rear sensor 8 below the rear display unit 23. Immediately after the display portion 24 is formed.

It should be noted that these display units 21 to 24 may be those in which a plurality of liquid crystal panels corresponding to the respective sensors 3, 4, 6, and 8 are integrated in advance, but each sensor is provided on one continuous liquid crystal panel. The images corresponding to 3, 4, 6, and 8 may be divided and displayed, and may be appropriately switched or the display range may be changed.

Further, the display 9 is not provided at the front end portion of the roof 5 in place of the room mirror, but may be attached to the front surface of the room mirror later. In addition, it may be arranged on the dashboard 25 instead of the roof 5.

Further, the rear sensor 6 at the rear end of the roof 5 may be deleted, and the rear display portion 23 of the display 9 may be replaced with a reflecting mirror similar to a conventional room mirror.

Alternatively, similarly to this, the rear sensor 6 may be removed, and as shown in FIG. 4, a display 31 in which the rear display unit 23 is removed from the display 9 may be provided side by side with the room mirror 32. . In this case, the left and right diagonal rear display sections 21 and 22 and the vehicle body rear display section 24 are substantially the same as the display 9 described above. Furthermore, it is possible to adopt a mode in which the left and right diagonal rear display portions 21 and 22 and the vehicle body rear display portion 24 are separated from each other.

If the rear image displayed on the above display is configured so that the image can be enlarged / reduced by a switch operation in the vehicle interior, usability is improved. Further, when the amount of light is insufficient at night or the like, by configuring the light projecting device to interlock, it is possible to obtain an image that is the same as during the daytime. On the other hand, if the sensors 3, 4, 6, and 8 are infrared sensors, the same effect can be obtained without providing a light projecting device.

[0018]

As described above, according to the present invention, since it is possible to perform rearward visual confirmation almost at the same time as rearward visual confirmation by the reflection image of the vehicle interior endoscope, rearward confirmation is facilitated and safety is improved. It has a great effect on raising the price.

Furthermore, in addition to the obliquely rearward image, an image immediately after the vehicle body, which is a blind spot, and a rearward image, which is substantially similar to the reflection image reflected in the room mirror, are obtained so that they are arranged adjacent to each other. This makes it possible to perform rearward confirmation with almost no problems, which makes it possible to further enhance safety. Moreover, since the arrangement position is not limited unlike the case of the rear endoscope, the display can be arranged at a position and an angle that are easily visible to the driver, which improves usability.

In particular, if the oblique rear image is arranged on both left and right sides of the rear image and the image immediately behind the vehicle body is arranged below the rear image, the driver can easily understand the relationship between the images on the respective display means. However, it is possible to quickly check the rear without being confused, which is extremely effective in facilitating the rear confirmation.

Further, if these display parts are integrally formed and then provided on the vehicle interior side of the roof front end instead of the room mirror or by being fixed to the front surface of the room mirror, it is relatively simple. It can be installed in the vehicle, and it has the advantage that it is easy for the driver to visually recognize and does not give a sense of discomfort.
