Description

Vehicle warning system for the hearing impaired {WARNING SYSTEM FOR HEARING-IMPAIRED PERSON OF VEHICLE}

The present embodiment relates to a vehicle warning system for the hearing impaired.

Hearing impaired persons are persons who cannot hear sounds such as voices and sounds due to congenital or acquired hearing loss, and are exposed to a myriad of discomfort and danger due to the loss of hearing in everyday life. In particular, as vehicle distribution becomes popular and it is possible to obtain a driver's license for the hearing impaired, the proportion of the hearing impaired directly driving a vehicle is gradually increasing. However, the hearing impaired is relatively exposed to traffic accidents and safety accidents compared to the non-hearing impaired because he/she must recognize all surrounding situations only through sight when driving.

In general, horn sounds and alarm sounds are widely used for the purpose of providing emergency or warning situations to others when driving a vehicle, and accordingly, drivers recognize surrounding conditions through horn sounds and alarm sounds generated by other vehicles. At the same time, traffic accidents can be prevented. At this time, the sound signals generated during vehicle operation are classified into alarm sounds such as emergency vehicles, fire engines, police cars, and lekka cars, collision and sudden brake sounds, and alarm sounds such as railroad crossing breakers, etc., and drivers immediately use these sound signals. It becomes possible to perform defensive driving while recognizing the surrounding situation.

However, since hearing impaired people cannot hear frequently occurring acoustic signals such as horns when driving a vehicle, and must recognize all surrounding situations only with sight, they are easily fatigued due to excessive tension when driving. Due to delay in recognition, it is not possible to perform prompt and appropriate responses, leading to traffic accidents frequently. In order to solve this problem, a study on a vehicle safety system for a driver with a hearing impairment is needed.

The present invention has been proposed in order to improve the above problems, and provides an alarm system for a vehicle capable of promptly responding and ensuring safe driving by immediately transmitting audio information of a driving road to a driver with a hearing impairment. There is a purpose to do.

The vehicle alarm system according to the present embodiment includes: a sensing unit disposed on an outer surface of the vehicle and including a sensor for detecting sound; A steering wheel disposed in the vehicle to control steering of the vehicle; A display unit disposed on the front surface of the handle and including an indicator light to display light; And a controller configured to output visual information corresponding to the determined sound to the display unit based on the sound information sensed by the sensing unit.

Through this embodiment, by receiving sound information generated outside the vehicle and providing it to the driver as visual information through the display, it is possible to immediately transmit the road situation to the driver with a hearing impairment, and to ensure safe driving. There is an advantage.
