摘　　要：针对车辆底盘动力学模型仿真过程中普遍存在计算效率低的问题,提出了一种包含不同子模型的车辆底盘自适应动力学模型。该自适应模型能根据不同的行车工况,自动匹配计算效率最高、求解精度满足要求的底盘动力学模型。利用MATLAB/Simulink仿真平台,将自适应模型、复杂度较高的动力学模型及CarSim车辆动力学模型进行不同工况下的仿真对比分析。双移线、圆周工况以及综合工况下的仿真结果表明:与其它两种模型相比,所提出的自适应模型在保证结果精度的前提下,具有更高的计算效率。A vehicle chassis adaptive dynamics model with different sub-models was proposed to address the common problem of low computational efficiency in the simulation process of vehicle chassis dynamics.The proposed adaptive model could automatically match the chassis dynamics model with the highest computational efficiency and satisfactory solution accuracy according to different driving conditions.Using the MATLAB/Simulink simulation platform,three different models,such as the adaptives model,dynamics model with high complexity and CarSim vehicle dynamics model,were simulated,compared and analyzed under different working conditions.The simulation results under double line change,circular working condition,and comprehensive working condition show that compared with the other two models,the proposed adaptive model has higher computational efficiency while ensuring the accuracy of the results.
