Fuzzy logic steering control of autonomous vehicles insideroundabouts

Abstract : The expansion of roads and the development of new road infrastructures have increased in recent years,linked to the population growing in large cities. In the last two decades, roundabouts have largely replacedtraditional intersections in many countries. They have the advantage of allowing drivers continuous flowwhen traffic is clear, without the usual delay caused by traffic lights. Although roundabouts with andwithout traffic-signal control have been widely used and considered in the literature, driverless control onroundabouts has not been studied in depth yet. The behavior of autonomous vehicles in roundabouts canbe divided into three stages: entrance, inside, and exit. The first and last may be handled as an extension ofintersections. However, autonomous driving on the roundabout requires special attention. In this paper,the design and implementation of a fuzzy logic system for the steering control of autonomous vehiclesinside the roundabout is proposed. Cascade architecture for lateral control and parametric trajectorygeneration are used. Fuzzy control has proved to be easy to define using expert knowledge. Experimentswith a real prototype have been carried out, taking into account different speed profiles and lane changemaneuvers inside the roundabout, with very satisfactory results.
