Compared with articulated vehicles with a single trailer, long combination vehicles (LCVs) with a tractor/two-trailer combination can improve fuel economy and reduce greenhouse gas emissions. However, the poor directional performance of LCVs restricts their applications. Although active safety systems (ASSs) have been developed to provide active steering, differential braking, and antiroll control for passenger cars, little attention has been paid to LCV safety systems. Because of the complex configurations and large sizes of LCVs, these vehicles exhibit unique dynamic behaviors, such as jackknifing, which may lead to fatal accidents. The proposed research develops new active safety technologies to increase the safety of LCV operations. The essence of ASS design is to construct a controller(s) to work with the driver to accommodate varied operating conditions. Current ASS design methods have not adequately addressed the driver-vehicle-road (DVR) interactions. The proposed program will focus on the following interrelated innovative investigations: 1) Integrated control of active steering and differential braking. To accommodate varied LCV operating conditions on highways, the control subsystems of active steering and differential braking will be integrated. 2) Design of ASSs using dynamic game theory. To address the interactions of DVR in the design, the design problem will be represented by a noncooperative dynamic game framework. Two 'players', namely, the driver and integrated controller, work together to increase LCV safety in various highway environments. 3) Validation of ASSs using real-time simulations. To evaluate the ASSs, driver-hardware-in-the-loop real-time simulations will be conducted. 4) Development of innovative design methods for ASSs. The ultimate research goal is to develop a multilevel design optimization method that considers the various uncertainties, e.g., variations in vehicle payloads. This research program will contribute significantly to the advancement of closed-loop dynamic system design through its innovative application to the design of complex mechatronic vehicle systems.

与单挂车的铰接式车辆相比，采用牵引车/双挂车组合的长挂车（lcv）可以提高燃油经济性，减少温室气体排放。然而，lcv定向性能差限制了其应用。虽然主动安全系统（ASSs）已经被开发出来，为乘用车提供主动转向、差速制动和防滚控制，但LCV的安全系统却很少受到关注。由于轻型商务车结构复杂、体积庞大，这些车辆表现出独特的动态行为，如弯折，可能导致致命事故。本研究旨在开发新的主动安全技术，以提高LCV运行的安全性。
