With direct yaw-moment control ( DYC) as example, the effects of the non-ideal onboard net-work conditions ( e. g. communication delay, data packet missing) of four-wheel-independent-drive electric vehicle (4WID-EV) on vehicle dynamics control are analyzed by simulation. The results indicate that non-ideal onboard network conditions could have significant negative influence on the timeliness and stability of vehicle dynamics con-trol, but the DYC algorithm based on network prediction can effectively compensate the adverse effects of communi-cation delay and data packet missing, achieving better control results.%以直接横摆转矩控制为例，通过仿真初步分析了四轮独立电驱动车辆分布式控制系统中车载通信网络的非理想状况(延时、丢包等)对车辆动力学控制的影响。仿真结果表明，通信延时等非理想网络状态会对车辆动力学的控制效果和稳定性产生显著影响，而基于网络预测的直接横摆转矩控制算法，可有效补偿通信延时和丢包等的不利影响，获得较好的控制效果。
