汽车操纵稳定性客观评价方法综述

汽车操纵稳定性评价是汽车动力学研究中最重要的研究内容之一。目前，汽车设计最终的评价、调校阶段基于主观评价,为了要在样车生产出来之前即可在虚拟样机上预测和评价汽车操纵稳定性，就需要有一套可在计算机上实施的客观评价体系。汽车操纵稳定性客观评价主观化是操纵稳定性评价指标体系的研究目的和难点,一种方法是通过线形回归方法建立主客观评价指标之间的关系，这方面的研究较多但没有形成最终统一明确的客观指标体系。本文将详细介绍汽车操纵稳定性客观评价的发展历史、评价方法、研究现状及展望，以及基于人车闭环系统中驾驶员模型的参数来评价汽车操纵稳定性的研究现状。

Review of Objective Vehicle Handling Evaluation

Vehicle handling evaluation is one of the most important research parts in vehicle dynamics.Currently,the tuning and final sign-off of a vehicle’s handling setup relies on subjective evaluation by experienced test engineers on roads and test tracks.To evaluate the virtual prototypes in computer,there is a need for some objective evaluation approaches.Setting up an objective evaluation system that could replace the subjective one during design phase is the aim of this research and is of great difficulty.Linear regression have been used a lot to establish the relationship between subjective and objective evaluation metrics,but it does not work well to conclude a clear objective evaluation system.The development and history,method,present and possible future research of vehicle handling evaluation,and another promising approach based on the driver model in the closed-loop system to evaluation the vehicle handling performance are reviewed.
