摘要
采用“状态转移”控制分析方法 ,将整车的控制分为相对独立的控制状态 ,详细分析了在不同工况下的控制状态之间的相互跳转。以双轴并联单离合器结构的 HEV进行了多能源动力总成的设计为例 ,对某一混合动力车辆的起步、行驶和制动等工况的控制进行了分析。采用混合动力车辆专用分析软件 Psat进行了控制仿真研究。结果表明 ,该方法能有效地解决混合动力车辆多能源管理系统设计困难的问题。
A key technology in designing hybrid electric vehicle (HEV) is how to control the multi-energy power unit. This paper developed a strategy of state shift to analyze the control mentioned. This strategy listed all the respectively independent states and then analyzed the shift from one state to another under any operation. Based on this strategy, this paper designed a multi-energy power unit for a double-axis, parallel, single clutched HEV and analyzed the control of starting, running and braking operations over a HEV. Finally, the paper simulated the control with Psat, a software specially used for HEV analysis. The simulation result indicated that this strategy was able to eliminate the difficulty of designing the management system of the HEV multi-energy power unit.
