摘　　要：针对传统的汽车设计教材着重于汽车结构设计,已经不能满足智能汽车设计要求,提出对传统汽车设计教材进行改革。首先以转向系设计为例,分析了传统汽车设计教材内容的不足之处,提出增设汽车转向系动力学性能分析内容。然后分析了汽车转向系动力学性能中操纵稳定性的评价指标,以综合评价指标为优化目标进行了横摆角速度增益值优化仿真分析,仿真结果表明,基于汽车转向系动力学性能参数的优化方法能够精确地评价汽车操纵稳定性,为学习智能汽车技术提供理论基础知识。Traditional automotive design textbooks,which primarily focus on automotive structural design,are no longer sufficient to meet the requirements of intelligent automotive design.Therefore,it is proposed that the content of these textbooks needs to be reformed.Taking the design of the steering system as an example,this paper analyzes the deficiencies of traditional automotive design textbooks and proposes the addition of content on automotive dynamics performance analysis.Subsequently,the evaluation indicators for the handling stability in the dynamics performance of the automotive steering system are analyzed.With comprehensive evaluation indicators as the optimization objective,a simulation analysis of yaw rate gain value optimization is conducted.The simulation results indicate that the optimization method based on automotive steering system dynamics performance parameters can accurately evaluate vehicle handling stability,which provids theoretical basic knowledge for learning intelligent automotive technology.
