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.

与带有单个拖车的铰接式车辆相比，带有拖拉机/两拖车组合的长组合车辆（LCV）可以改善燃油经济性并减少温室气体排放。但是，LCV的方向性差限制了其应用。尽管已经开发了主动的安全系统（ASS），以提供主动转向，差速器制动和乘用车的防托管控制，但对LCV安全系统的关注很少。由于具有复杂的配置和大尺寸的LCV，这些车辆表现出独特的动态行为，例如具型式行为，这可能导致致命的事故。拟议的研究开发了新的主动安全技术，以提高LCV操作的安全性。
