摘　　要：提出了一种车辆稳定性控制系统,基于分布式结构的分析方法,通过合理分布复杂的控制算法将控制系统分为控制分析、控制分配和控制执行3个层次。在控制分析层采用了滑模变结构控制方法,计算出车辆期望作用力和横摆力矩。使用非线性优化方法将期望值分配到4个车轮上,实现并优化了控制分配效果。在CarMaker车辆动力学分析环境中进行了仿真分析,结果表明设计的控制算法提高了车辆在极限工况下的稳定性,降低了驾驶员驾驶强度。An analytical method for vehicle stability control system is proposed based on distributed control structure. By distributing complex control algorithm, the control system is divided into three layers, which are control analysis, control allocation and control actuation. The desired forces and yaw moment are calculated based on sliding mode control method in control analysis. Then these are allocated to proper four wheels by using nonlinear optimal theory, in which the control allocation is realized and optimized. Simulations are implemented in the virtual vehicle dynamics environment CarMaker, and the results indicate that the designed control system enhances the vehicle stability in extreme condition and reduces the driver＇s burden.
