摘要:
针对速度变化对插电式混合动力汽车(PHEV)经济性的影响,提出一种顺序速度平滑控制策略.通过对给定交通约束条件下的速度曲线进行顺序平滑处理,优化充电策略,提高插电式混合动力汽车的燃油经济性.根据前车速度的预测值,在车辆与前车的可接受跟踪距离范围内,通过最小化加速度来平滑车速;采用最优的充电耗散策略,根据整个行程的信息,将电池充电延长到行程结束.通过对3种典型工况测试周期的组合,研究商用PHEV的连续优化对两种不同行驶模式的影响.仿真结果表明:所提出的顺序优化方法由于与车辆结构无关,实用性较高;由于在速度优化中使用线性车辆模型求解最优控制问题,因此计算过程的实时性较好;速度平滑控制方法使燃油消耗量减少7%~14%.
Abstract:
A sequential velocity smoothing control strategy was proposed for the impact of velocity changes on the economy of plug-in hybrid electric vehicles(PHEV). The fuel economy of plug-in hybrid electric vehicle was improved by smoothing the speed curves in a given traffic constraint in order to optimize the charging strategy. According to the predicted speed value of the car in front, within the acceptable tracking distance from it, the speed was smoothed by minimizing acceleration. Meanwhile, the optimal charging dissipation strategy was adopted to extend the battery charging to the end of the journey according to the information of the entire journey. The effect of continuous optimization of commercial PHEV on two different driving modes was studied by combining three typical test cycles. The simulation results show that the proposed sequential optimization method has high practicality because it has nothing to do with vehicle structure. Because the linear vehicle model is used to solve the optimal control problem in speed optimization, the real-time performance of the calculation process is better. Fuel consumption is reduced by 7% to 14%.
