The main content of this paper is the development of collision avoidance system using ultrasonic wave during parking, In a modern society where automobiles are commonplace, When many people leave the car after parking, they unconsciously open the car door quickly or strongly and collide with someone else's car It is a system developed to minimize scratches on each other's cars. Despite the fact that many anti-collision items are already on the market, the reason for developing this system is that there are many disadvantages on the market. Items that are currently released can not be seen until the door of the vehicle reaches the other vehicle. But the key element of our system is that we can see the crash before reaching the other vehicle. The ultrasonic sensor attached to the interior of the vehicle door before the collision with another vehicle emits an ultrasonic wave to measure the distance to another vehicle. When the distance is narrowed to a certain distance, a sound sensor sound is generated to inform the driver. This allows the driver to be aware of the risk of collision before impact. Due to the development of this system, collision accidents caused by getting off the parking lot are reduced Personally, I can save the repair cost of a simply useless car, Nationally, the number of traffic accidents is reduced, and the annual vehicle repair costs can be considered.
