2. Description of the Related Art An automobile driver visually confirms the surrounding conditions. Therefore, for example, when confirming the front, information on the other visual fields such as the lateral visual field and the rear visual field cannot be obtained. In this situation, if an emergency occurs in a place that is not visible, it will be unrecognizable or delayed, and a serious situation will occur when it falls into a dangerous state.

A human's visual field is usually about 120 degrees, and if one stares at it while driving, it may be narrowed to several tens of degrees. Therefore, it is an object of the present invention to provide information for safe driving by displaying information in directions other than the front direction on a monitor or the like near or within the visual field where the driver is monitoring the road conditions ahead.

The driver repeats the operations shown in FIGS. 1 to 4 while driving the vehicle, depending on the surrounding conditions. Assuming that the driver is gazing ahead ahead, information other than the area ahead cannot be obtained at all, so the driver is thinking about the surrounding information obtained in the past in a deductive manner. If an unforeseen event occurs in front of you, it will take more time to stare ahead, and it will be even slower to obtain new information about your surroundings.
At this time, a new situation may occur in the surroundings until the next time the location is visually inspected, and if the situation suddenly changes, an emergency may occur. The driver repeatedly checks the front, side, and rear situations during driving all the time to confirm safety. These actions make up a large proportion of the driver's driving work time, which poses a serious problem in ensuring safety.

An example of this application will be described with reference to FIG. Right turn car 8
1 is stopped at the right turn stop position, and the right turn oncoming vehicle 84 is stopped at the front left. Since the right-turn vehicle 81 has a right-turn oncoming vehicle 84, the field of view in front of the right side is poor, and the oncoming straight vehicle 83
Cannot be recognized. However, in the case of an automobile equipped with the system of the present invention, the forward field of view is 82, and therefore the oncoming straight ahead vehicle 83 can be found early.

As an example of the monitor screen switching method,
For example, the right side screen may be displayed when the driver turns the steering wheel to the right to turn right, or the already displayed right side screen may be enlarged. The monitor may be installed at a place where instruments are attached, the car navigation monitor may be shared, or the monitor image may be projected on the fluent glass. When the driver is monitoring the situation outside the vehicle, the focus of the eyes is far, so it is better to correct the focus of the image on the monitor so that the far point is in focus.
