Simulation of Emergency Lane-Keeping Systems for Vehicle Safety in Critical Situations

This thesis investigates how Emergency Lane-Keeping Systems can be used to enhance vehicle safety in times of need. Correspondingly, a testing framework based on advanced simulation tools was developed for testing ELKS performance and effectiveness under numerous emergency scenarios. The main idea behind it is to ensure robust lane-keeping performance to increase the vehicle's safety during critical events. Simulation and visualization of numerous traffic conditions, from dense lane changing to emergency brake applications, are achieved within the integrated platforms. From these scenarios, many test cases were developed. The test cases included the ability of the ELKS to correctly detect lane markings, maintain lane discipline, and avoid collisions in response to it. The use of advanced simulation platforms made the simulation environment even more realistic and, at the same time, made it possible to generate traffic scenarios and vehicle interactions, along with response, while remaining synchronized. Besides that, real-time synchronization between the traffic simulation and its visualization made the system more precise in showing the vehicle dynamics and emergency responses. Thus, this system gave a great deal concerning the performance of ELKS in vehicle lane discipline and accident-free driving under variable conditions. The enhanced autonomous drive system controls the test vehicle during the final testing phase. Parameters were systematically modified to elicit emergency lane changes, while other simulated vehicles helped in generating a dynamic and challenging traffic environment. It could thus help in testing the strength and adaptability of ELKS. The study has shown that with the aid of this integrated simulation platform for critical scenarios, ELKS could be validated. Simulations have also indicated the high effectiveness of the ELKS at preventing the car from leaving the lane and avoiding collision. The system was tested under various traffic densities and road geometries, indicating remarkable potential to boost vehicle safety.
