摘　　要：汽车行驶过程中需要变道和转向,驾驶员通过汽车转向系统,使汽车改变行驶方向。汽车方向盘是驾驶员直接接触的物体,车辆转向性能的好坏,不仅关系到汽车的安全性能,还直接关系到用户操作的舒适性。在汽车转向性能开发中,需要进行电动助力转向曲线调校评价测试,以满足整车转向性能要求。文章主要介绍电动助力曲线原理、调校方法,以及调校时的转向性能评价测试,对后续转向性能开发有一定的指导意义。When a car is on the move,lane changing and turning are often needed.Drivers manipulate the steering system to alter the vehicle's direction.The steering wheel is the part that driv-ers come into direct contact with.The quality of a vehicle's steering performance is crucial as it not only impacts the safety of the vehicle but also directly determines the comfort level of the user's opera-tion.In the development of vehicle steering performance,evaluation tests for calibrating the electric power-assisted steering curve are essential to meet the overall steering requirements of the vehicle.The principle of the electric power-assisted curve,the calibration methods are elaborated,as well as the steering performance evaluation tests during calibration,which provides certain guiding signifi-cance for subsequent steering performance development.
