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

该项目的目标是开发一种具有主动拖车转向(ATS)系统的多拖车铰接式车辆(MTAV)的集成设计方法。在当地道路和城市街道上低速行驶时，MTAV的机动性很差。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会导致致命的事故。为了解决操纵性差的问题，“被动”挂车转向系统应运而生。这些系统改善了低速性能，但在高速下稳定性较低。一些主动的挂车转向系统已经被提出以提高高速稳定性。然而，这些ATS系统在低速应用时通常会降低机动性。针对这一复杂的权衡设计问题，提出了一种系统化的设计方法。

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.
