Development of automated parallel parking system in small mobile vehicle

Abstract

Collisions can happen during reversing or parking the car especially in the limited space. Since many drivers acknowledge that parallel parking is a very tedious task. This research aims to develop the parallel parking system by developing small mobile vehicle as a model. Design of prototype vehicle is considered for the real-life parallel parking. Hence, it can detect a parking space, execute the parking maneuver, avoid hitting the front, rear obstacles and reduce the time for parking. The parking maneuver is simplified by choosing the optimum turning angle for both the first and second parts of the parking maneuvers. At the first stage, ultrasonic sensors sense the parking environment and if the space is sufficient, a safe parking maneuver is generated. In second stage, positioning phase, the mobile vehicle will execute reverse motion into the parking space without any collisions. The last stage, it moves to the correct parking position in the parking space while adjusting itself to a safe distance from front and rear obstacles respectively. It is discovered from the result that developed system required just 1.33 times longer parking space than vehicle overall length. Small mobile vehicles successfully able to manage the parallel park itself without hitting or touching front and rear obstacles.
