汽车的稳态转向特性目前主要通过场地试验的方法获得，文章探讨采用汽车力学参数的测量结果预测汽车稳态转向特性的方法。根据影响汽车稳态转向特性的各项因素与不足转向度之间的内在关系，以在汽车力学参数试验台上实测的汽车力学参数数据为基础，采用曲线拟合方法，并加入汽车的轮胎特性，对被试车辆的不足转向度进行了预测。预测结果与试验场地实测结果的对比表明两者具有较好的吻合性。研究结果表明利用汽车的力学参数预测稳态转向特性具有不受环境影响、易于辩识影响因素等优点
The steady-state steering characteristics of vehicles are mainly obtained through field tests. The article discusses the method of predicting the steady steering characteristics of automobiles by using the measurement results of automobile mechanics parameters. According to the intrinsic relationship between the factors that affect the steady steering characteristics of automobile and the degree of steering, based on the data of automobile mechanics parameters measured on the automobile mechanics parameter test stand, the curve fitting method is adopted and the tire characteristics , The lack of test vehicle steering was predicted. The comparison of the predicted results with the measured results of the test sites shows that the two have good agreement. The results show that using the vehicle’s mechanical parameters to predict steady-state steering characteristics has the advantages of being independent of the environment and easy to identify the influencing factors
