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

该项目的目标是为带有主动拖车转向（ATS）系统的多拖车铰接车辆（mtav）开发一种集成设计方法。mtav在局部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，包括翻车。这些不稳定的模式可能导致致命的事故。为了解决机动性能差的问题，“被动”拖车转向系统已经被开发出来。这些系统提高了低速性能，但在高速下表现出较低的稳定性。为了提高拖车的高速稳定性，人们提出了一些主动转向系统。然而，这些ATS系统在低速应用时通常会降低机动性。为了解决这一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.
