Integrated design of multi-trailer articulated vehicles with active trailer steering systems

本计画的目标是发展一套整合式设计方法，用于多拖车铰接式车辆（MTAVs）与主动式拖车转向系统（ATS）。MTAV在当地道路和城市街道上低速行驶时机动性差。另一方面，MTAV在高速下表现出不稳定的运动模式，包括翻滚。这些不稳定的模式可能导致致命的事故。为了解决机动性差的问题，已经开发了“被动”拖车转向系统。这些系统改善了低速性能，但在高速时表现出低稳定性。已经提出了一些主动拖车转向系统来改善高速稳定性。然而，这些ATS系统在低速应用时通常会降低机动性。为了解决这个复杂的权衡设计问题，提出了一种系统的设计方法。

The goal of the project is to develop an integrated design method for Multi-Trailer Articulated Vehicles (MTAVs) with Active Trailer Steering (ATS) systems. MTAVs have poor maneuverability when traveling at low speeds on local roads and city streets. On the other hand, MTAVs exhibit unstable motion modes at high speeds, including roll-over. These unstable modes may lead to fatal accidents. To address the problem of poor maneuverability, 'passive' trailer steering systems have been developed. These systems improve low-speed performance, but exhibit low stability at high speeds. Some active trailer steering systems have been proposed to improve high-speed stability. However, these ATS systems typically degrade maneuverability when applied at low speeds. To tackle this complex trade-off design problem, a systematic design method is proposed.
