[Supplementary explanation of the above embodiment]
The present invention is not limited to the above embodiment. For example, a plurality of indicators as forward notification means, intermediate notification means, and backward notification means may be arranged. Furthermore, in this case, the lighting color (or blinking color) of the indicator that informs that an obstacle is present may be different from the lighting color (or blinking color) of the indicator that informs that there is no obstacle. Good. For example, when there is an obstacle, it is possible to use red lighting that prompts a warning, and when there is no obstacle, it is possible to perform green lighting that promotes safety.

  In the present invention, the lighting color may be different between the indicator as the forward notification means and the indicator as the backward notification means. For example, the lighting color of the indicator as the front notification means is blue, and the lighting color of the indicator as the rear notification means is yellow. The position can be recognized.

  Moreover, you may change a shape with the indicator as a front alerting | reporting means, and the indicator as a back alerting | reporting means. For example, one indicator can be triangular and the other indicator can be square. In addition, the present invention can use indicators having the same shape but different directions. For example, the front indicator may have a triangular shape having an apex angle on the front side of the vehicle, and the rear indicator may have a triangular shape having an apex angle on the rear side of the vehicle. In the present invention, symbols, characters, and the like that are visually recognized by lighting or blinking and that indicate directions may be provided on the display surface of the indicator. With such a configuration, it is possible to further contribute to intuitive recognition of the position of an obstacle.

  In the present invention, sensors as front detection means and rear detection means may be arranged on the vehicle side such as a front part, a rear bumper or the vicinity thereof. The sensor as the intermediate detection means may be arranged on the side door. Further, the sensor may be provided inside the visor of the door mirror device or on the outer wall as the detection means.

  Further, in the present invention, an indicator serving as a front notification unit, a rear notification unit, or an intermediate notification unit may be disposed in a room mirror device in the vehicle interior. In the present invention, these indicators may be arranged in a fender mirror device or a fender side auxiliary mirror device. Further, in the present invention, the obstacle on the upper side of the mirror is detected by the front detection means, the rear detection means, and the intermediate detection means, and the detection result may be notified by the front notification means, the rear notification means, and the intermediate notification means. . Here, the obstacles above the mirror include, for example, a tree branch, a roof installed in a parking lot, and the like.

  In the present invention, the obstacle notification system may be provided only on one of the right side and the left side of the vehicle. Generally, since it is difficult to grasp the presence of an obstacle on the passenger seat side with respect to the driver seat side of the vehicle, the obstacle notification system is preferably provided on the passenger seat side.

  Furthermore, the present invention may be configured to detect the vehicle front side and the vehicle rear side of the mirror with one sensor without providing a plurality of front sensors and rear sensors, or front sensors, middle sensors and rear sensors as detection means. Good.

  Further, the present invention may replace the middle indicator as the intermediate notification means by turning on (or flashing) both the front indicator as the front notification means and the rear indicator as the rear notification means.
