Description

Traffic safety indicating device using vehicle OBD and driving method thereof {Traffic safety indicating Apparatus using OBD and Driving Method Thereof}

The present invention relates to a vehicle safety display device, and more particularly, a vehicle safety display device using a vehicle OBD that informs a vehicle or a motorcycle, etc., in advance of whether a door of a vehicle is opened in order to prevent an accident when a passenger gets on or off. And a driving method thereof.

In general, commuter vehicles or school vehicles are mainly composed of large buses, such commuter or school vehicle is the door is only on the left side of one side of the vehicle passengers are to get on and off through only one side door.

That is, when getting on and off, the vehicle stops on the side of the sidewalk on the left side of the road, gets on the sidewalk from the sidewalk, and gets off the sidewalk from the sidewalk.

By the way, there is no risk of accidents from the surrounding vehicles because the riders are already assembled in India, but when getting off, the road through the front of the vehicle stopped when the rider gets off the road and goes to the destination. If you cross the road will cause traffic accidents.

In particular, in the case of school buses or school vehicles, since most of them are infants or children, they can cross the road where other vehicles are traveling in front of or behind the vehicle, and thus have a problem of increasing the risk of traffic accidents.

If children try to cross the road ahead of the vehicle, other vehicles driving on the right side of the stopped vehicle will not be able to predict in advance who will jump out of the vehicle in front of the stopped vehicle. Because it is a large vehicle such as a bus, its height is so high that it does not let other vehicles running from afar realize the situation in front of the vehicle.

In addition, the stopped vehicle will keep both flashing lights to indicate a stopped state, and will inform other vehicles of slowing or stopping, but it may pass through the front of the vehicle to infants or children who are not aware of the traffic situation. If you pop out before you can see if the other vehicle is running, it is very difficult for the other vehicle that is driving to recognize this, which leads to a very dangerous situation.

In consideration of such a problem, recently, a traffic law was enacted to stop a vehicle carrying an infant or a child so that other vehicles around the vehicle are stopped once upon getting on and off. However, the technology that displays the situation indication that the infant or child is getting on and off the vehicle is not so much proposed, so this situation is urgently required.
