摘　　要：针对三轴独立电驱动结构形式的混合动力车辆,提出了多轴独立电驱动系统的驱动力分层协调控制方法。首先建立多轴驱动转矩协调控制系统的分层控制结构,将控制系统划分为理想路面下的总需求驱动力矩分配层(上层)、驱动工况下的单轴驱动防滑控制层(下层),以及在上下层出现矛盾时进行协调控制的协调层(中层)。在完成了多轴驱动转矩协调分配控制策略的设计之后,在MATLAB/Simulink环境下开发了前向仿真模型,对控制策略进行了仿真分析。在此基础上,通过实车试验对该控制策略进行了试验验证和评价。结果表明,所提出的协调控制系统实现了对车辆有效、可靠的控制,提高了电机系统的效率和车辆的通过性。A coordinated hierarchy control strategy of driving torque was developed for multi-axles（especially three-axles） independent electric driving hybrid vehicles.The control system is divided into three layers based on the hierarchical control theory,with the allocating layer（upper layer） allocating the total driving torque required on an ideal road,with the traction control layer（lower layer） avoiding the skid of a driven axle,and with the coordinating layer coordinating the inconsistency between the upper and lower layers.After the design of the coordinated distribution control strategy,a forward simulation model for the series hybrid electric vehicle propulsive system was developed under the MATLAB/Simulink environment,with detailed simulation analysis then made and the control strategy validated,while the strategy was used on a test vehicle for validation and evaluation.The results show that the coordinated control system can control the vehicle effectively and reliably with improved motor system efficiency and vehicle trafficapability.
