摘　　要：为改善独立驱动电动汽车CAN控制的实时性和可靠性,以自主研发的汇聚式双电机独立驱动系统为控制对象,针对其CAN分布式控制问题,进行了系统功能原理说明与控制网络构建,利用RM算法实现CAN调度优化设计并结合抖动裕度指标进行实时性可预知分析,最后利用CANoe,Matlab/Simulink和电动汽车双电机驱动测试实验系统分别进行仿真和硬件在环控制实验验证,结果表明设计的独立驱动系统CAN控制方案具有较高的实时性和可靠性,能够满足独立驱动电动汽车的应用要求。To improve real time and reliablity of CAN control for independent driven EV （IDEV）, an agglomerative double-motor independent driven system is developed, then work including system primary function introducation, control network modeling, schedule optimization design based on RM and real-time foreseeable analysis with jitter margin is researched.At last the design is simulated with CANoe software ,Matlab/Simulink and tested with double- motor detection system for EV.The results show this new CAN control scheme for the independent driven system is more real-time and rehable for IDEV.
