A Prototype car guidance system for automatic parking using the DT-Sense ultrasonic ranger

Abstract

Damage to the car body is one of the things that a driver must avoid, especially when parking his car in a narrow space. This can be caused by the driver’s limited vision at night towards the back of the car. This can be avoided if there is a guidence system for the driver. Therefore, in this study a guidance system for automatic parking using the DT-Sense ultrasonic ranger was developed. The sensor is used to measure the distance between the car and the wall surface of the parking area. The system is made based on a microcontroller 328. The novelty is the variation of tests carried out on the wall surface and the distance from the car to the parking area from 105 cm to 250 cm. The test results show that the error of measuring the distance of car with a flat surface is 4.26%, a convex surface is 2.82%, and a graded surface is 4.86%.
