Design and Evaluation of Active Trailer Steering Systems of Long Combination Vehicles Using Driver-Software-in-the-Loop Simulations 2012-01-0934

Vehicle simulators are often used for vehicle system development and driver behaviour study. The target of this study is to design and evaluate an Active Trailer Steering (ATS) system for a Long Combination Vehicle (LCV) with mutiple trailers using a real-time vehicle simulator. A linear yaw-plane LCV model is generated to derive an optimal ATS controller. Then, the controller is reconstructed in LabVIEW and integrated with a vehicle model for a B-train double from TruckSim. The Driver-Software-in-the-Loop (DSIL) real-time simulations are conducted with the vehicle simulator. The DSIL real-time simulations indicate that the ATS controller can effectively improve the LCV's low-speed maneuverability and high-speed stability under the test maneuvers of a low-speed 90-degree turn and a high-speed single-lane change, respectively. The investigation based on the DSIL real-time simulations paves the road to the future development of electronic control units (ECUs) for the ATS system using Driver-Hardware-in-the-Loop real-time simulations.
