Description

  The present invention relates to an approach notification device capable of notifying a pedestrian of the approach of a vehicle or the like.

  Normally, the human field of view is a normal person, and the range that can be seen simultaneously by both eyes is said to be 120 degrees left and right, and 180 degrees backward is a blind spot. In recent years, with the improvement in silent performance of vehicles such as hybrid vehicles (hereinafter sometimes abbreviated as “HV”) or electric vehicles (hereinafter sometimes abbreviated as “EV”), these vehicles have become too quiet. In addition, there is a problem of danger that a pedestrian may collide with a vehicle approaching from a blind spot of a pedestrian, such as in a general city street or a shopping street. Such a risk is particularly noticeable not only in healthy subjects but also in elderly people who are unable to walk or physically disabled people such as blind people. Therefore, how to realize both the demand for a “quiet society” and “ensure the safety of pedestrians” has become a social issue.

  Conventionally, there has been proposed a safety cane that is effective for seeking help from other people around a person who has a physical disability such as a blind person or a pedestrian such as an elderly person. More specifically, a cane with an illumination lamp has been proposed in order to clarify the presence of a pedestrian in a car or the like during night traffic. Also, a cane with a buzzer has been proposed in order to clarify the location of a pedestrian to a car or the like, or to transmit some will to the car or the like regardless of nighttime or daytime.

  However, these conventional canes have a drawback in that when an abnormality occurs in the user of the cane, it is not possible to inform the surroundings by voice and ask for help.

  As a measure to improve this, a safety cane has been proposed that can ask for help from people around the pedestrian by outputting sound or turning on a display in response to the user's switch operation. (See Patent Document 1).

Utility Model Registration No. 3021826

  However, the safety cane disclosed in Patent Document 1 outputs a sound or turns on a display triggered by a switch operation that relies on the sense of a pedestrian who is a user of the cane. Therefore, in a society where the pedestrian's hearing is difficult to work with the recent improvement in quiet performance such as HV or EV, the pedestrian's switch operation is not limited, and the pedestrian's blind spot is 180 degrees behind. There is a problem that the risk of collision between a vehicle approaching and the like with a pedestrian increases.

  Therefore, the present invention is an apparatus that enables a pedestrian to check a vehicle, a person, etc. approaching from behind, which is a blind spot of the pedestrian, and an approach notification apparatus that can ensure high safety of the pedestrian. The purpose is to provide.
