The influence of braking on dynamic stability of a car-trailer combination (CTC) is studied in this paper. The braking is simply modeled and integrated into a single-track model (STM) with a single-axle trailer. On this basis, some fundamentals and analysis results related to system dynamic stability are given through simulation. Furthermore, it is found that the axle load transfer and braking force distribution have a great influence on system dynamic stability. In order to further analyze the influence of these two factors, both of the braking force distribution and the pitch motion are considered in the modeling. Finally, the ideal braking force distribution domain is proposed. Results can be adopted to explain the experimental phenomenon and serve as a guideline for the differential braking strategy in stability control of the CTC.

制动对挂车组合动态稳定性的影响

本文研究了制动对汽车拖车组合（CTC）动态稳定性的影响。制动被简单地建模并集成到带有单轴拖车的单轨模型 (STM) 中。在此基础上，通过仿真给出了与系统动态稳定性相关的一些基本原理和分析结果。此外，发现轴荷传递和制动力分配对系统动态稳定性有很大影响。为了进一步分析这两个因素的影响，在建模中同时考虑了制动力分布和俯仰运动。最后，提出了理想的制动力分配域。结果可用于解释实验现象，并作为 CTC 稳定性控制中的差动制动策略的指导。
