摘　　要：本文根据汽车加速测试发现汽车转向某转数下存在抖动现象,经过路径径查找分析,快速找出由于发动机Z向到方向盘的响应传递路径存在问题,并找出问题根源。基于仿真与试验对标后模型进行问题改进,最终转向抖动问题得到明显改善。This paper, according to the car acceleration test, finds that the car has a jitter phenomenon under a certain number of rotations. After searching through the path diameter, the paper finds out the problem of the response transmission path from the engine Z to the steering wheel, and finds the source of the problem. Based on simulation and experiment, the post-subject model is improved, and finally the steering jitter problem is significantly improved.
