TORCS oyun ortamında bulanık mantık tabanlı akıllı bir otonom araç kontrol sistemi tasarımı

Öz

Bu çalışmada TORCS (The Open Racing Car Simulator) oyun ortamında bulanık mantık tabanlı otonom araç kontrol sistemi tasarımı yapılmıştır. Bu çalışmadaki amaç, aracın yol bariyerlerine çarpasını engelleyerek hiçbir zarar almadan ve yol sınırları içerisinde kalmasını sağlayarak pistin dışına çıkmadan yarışı tamamlamasıdır. Bu bağlamda, aracın otonom bir şekilde ilerleyebilmesi için bulanık mantık ve klasik kontrol yapılarından oluşan akıllı bir sistem geliştirilmiştir. Aracın vites geçişleri otomatik hale getirildikten sonra aracın gerçekçi bir şekilde hızlanması/yavaşlamasını sağlamak ve de aracın sabit bir hızda gitmesi için bulanık mantık tabanlı bir gaz/fren kontrol sistemi tasarlanmıştır. Ayrıca, aracın pistin dışına çıkmadan ilerleyebilmesi ve de virajlarda pist içinde kalabilmesi için bulanık mantık tabanlı bir direksiyon kontrol sistemi geliştirilmiştir. Geliştirilen bu uzman tabanlı sistem sayesinde, aracın önünde bulunan virajın yönüne ve keskinliğine göre de aracın bulunması gereken uygun pozisyon hesaplanmıştır. Geliştirilen akıllı kontrol sistemin oyun performansına https://youtu.be/qOvEz3-PzRo bağıntısından ulaşılabilir.

A fuzzy logic based intelligent autonomous vehicle control system design in the TORCS game environment

Abstract

In this study, a fuzzy logic based autonomous vehicle control system is designed and tested in The Open Racing Car Simulator (TORCS) environment. The purpose of this study is that vehicle complete the race without to get any damage with preventing to hit to the barriers and to go out of the way with staying in boundary of the road. In this context, an intelligent control system composed of fuzzy logic and conventional control structures has been developed such that the racing car is able to compete the race autonomously. Once the vehicle's gearshifts have been automated, a fuzzy logic based throttle/brake control system has been designed such that the racing car is capable to accelerate/decelerate in a realistic manner as well as to drive at desired velocity. The steering control problem is also handled to end up with a racing car that is capable to travel on the road even in the presence of sharp curves. In this context, we have designed a fuzzy logic based positioning system that uses the knowledge of the curvature ahead to determine an appropriate positon. The game performance of the developed intelligent control system can be observed from https://youtu.be/qOvEz3-PzRo
