How to measure the sound wave arrival time more accurately by reflecting the noise input in the vehicle opening/closing system using sound wave communication and to locate the distance

摘要

Disclosed is a method of more accurately measuring a sound wave arrival time and locating a distance by reflecting a noise input in a vehicle opening/closing system using sound wave communication. According to the present invention, it is possible to more accurately measure the sound wave arrival time and measure the distance by reflecting the noise input in the vehicle opening/closing system using sound wave communication based on the standard and method for filtering errors that may occur due to noise in general. .
