Evaluation of RI/Lateral Stability-based Rollover Mitigation Controller on a Virtual Test Track

다국어 초록 (Multilingual Abstract)

A full-scale driving simulator is a virtual reality tool for investigation of human driver behavior and testing vehicle control algorithms. This paper describes an evaluation of RI/Lateral Stability-based Rollover Mitigation (ROM) control algorithm for rollover prevention and lateral stability using full-scale driving simulator on a virtual test track (VTT). A rollover index (RI) which indicates an impending rollover is introduced to detect a danger of rollover. The RI/Lateral stability-based ROM controller is designed to reduce the danger of rollover without loss of vehicle lateral stability by integrating the electronic stability control (ESC). Since ROM controller always works with the driver, the overall vehicle performance will depend not on how well the controller works but rather on its interactions with the human driver. Vehicle behavior and interactions between the vehicle, the controller and the human driver are investigated using a full-scale driving simulator on VTT. The VTT consists of four parts; real-time simulation hardware which calculates the behavior of vehicle model on real-time, visual graphic engine which projects the visual representation of driving situation to the driver, human-vehicle interface in order to acquire the driver’s response and motion platform which applies the behavior of vehicle model to simulator body. The VTT makes it possible to evaluate the controller in the laboratory without risk of injury before filed testing and promises to significantly reduce development cost and cycle time.
