Description

  The present invention notifies a visually impaired person of the approach of a moving body such as an automobile with a low running sound, and the visually impaired person takes a posture and risk avoidance action, thereby causing a visually impaired person to suffer a personal accident or the like. The present invention relates to a method and an apparatus for enabling reduction of the risk of occurrence.

  In recent years, trains in Japan have been quieter and the noise generated during travel has been reduced, which is preferable for healthy people, but it is difficult for visually impaired people to detect the proximity of the train, and visually impaired people As a victim, there is an increased risk of encountering personal injury.

On the other hand, in the automobile industry, gasoline cars have been the mainstream, and the running noise is loud, so visually impaired people have been aware of the danger from the magnitude of the running noise and have taken danger avoidance actions. Problems related to automobile accidents such as personal injury caused by cars with low running noise were not taken up as too big problems. However, in recent years, hybrid vehicles and electric vehicles have been rapidly increasing due to the fossil fuel resource depletion problem and the global environment deterioration problem. This is a viewpoint from the viewpoint of the fossil fuel resource depletion problem and the global environment deterioration problem. Although it is preferable from the above, the advantage of low driving noise of hybrid cars and electric cars is the same as in the case of the above-mentioned train, it becomes difficult for the visually impaired to detect the proximity of the car, and personal injury etc. are encountered as a victim. The risk of doing this is increasing. In particular, the fear of visually impaired people at intersections is likely to increase immeasurably, and the risk of encountering car-related accidents, etc., is considered to increase dramatically rather than on the train. This problem must be taken seriously by the country and society, and concrete and effective solutions need to be presented before hybrid cars and electric cars become fully popular. However, with regard to this problem, the government and automobile-related companies / organizations have just started to work, and it is said that there is a plan to attach a warning sound generator to a moving body as a proposal for countermeasures. However, this scheme not only easily abandons the small advantage of the traveling sound of the moving body, but also may cause a new harmful effect due to the generation of an alarm sound, and is not necessarily an effective solution. A solution from the point of view that also considers the points and the problems that arise.

By the way, most of the technical proposals as conventional countermeasures for the visually impaired are, for example, a disabled person guidance device including a disabled staff, such as Patent Documents 1 to 3, and the like as described above. In addition, there are hardly any technical proposals that are directly related to a moving body such as an automobile that can reduce the risk of encountering a personal injury or the like of a visually handicapped person due to the approach of a moving body such as an automobile with a low running sound.

For this reason, in the current situation where full-scale spread of hybrid cars, electric cars, etc. with low running noise is imminent, the advantage of low running noise of mobile bodies such as hybrid cars, electric cars with low running noise is easy There is an urgent need for a technical proposal that can reduce the risk of a visually handicapped person who encounters a personal injury as a victim without being abandoned.

In addition, it is a radio wave reception / detection means capable of determining from which direction the received / detected microwave is emitted, and the voice transmission means is a voice transmission means capable of notifying the approach direction by voice. It is characterized by.

  Further, the radio wave receiving / detecting unit can calculate the distance between the visually impaired person and the moving body from the microwave received by the radio wave receiving / detecting unit, and the voice transmitting unit can also notify the distance information by voice. It is a means.

  Further, the apparatus further comprises a light emitting means for notifying a moving body or the like that the wearer of the apparatus is a visually impaired person in conjunction with the reception / detection of the microwave of the radio wave reception / detection means. .

  According to the moving object approach notifying method for visually impaired persons and the moving object approach notifying apparatus for visually impaired persons according to the present invention, even if a moving object such as a hybrid vehicle or an electric vehicle with a low running sound has spread, a hybrid vehicle, The visually impaired person can confirm and judge the approach of the moving body with low running sound without losing the advantage of the running sound of the moving body such as an electric vehicle. By taking the avoidance action, it becomes possible to reduce the risk that a visually impaired person will encounter a personal injury as a victim. Naturally, it can also be used for moving objects such as trains. Furthermore, if the mobile body approach notification device is a device having a light emitting means for notifying a visually impaired person in conjunction with reception / detection of microwaves, the driver driving the mobile body also moves forward. Since it is possible to visually recognize that there are visually impaired persons, the driver will drive with consideration for visually impaired persons, so that the risk of visually impaired persons experiencing personal injury as victims can be further reduced. become. And this method and apparatus can be expected to reduce the risk of encountering a personal injury as a victim by using children who have not yet developed their attention or elderly people whose attention has declined.
