为使混合动力电动公交车更加有效,开发了一种控制发动机和电动机之间的功率分布的监控策略。该混合动力公交车的监控器利用所采集的诸如海拔高度、车速和来自全球定位系统(GPS)接收器的路线图等信息,优化燃料经济性。在两种动力源之间,该控制算法使用了功率分配比(PSR)。通过动力学编程理论所导出的功率分配比(PSR)曲线,可以导出一种最佳控制方案。结果表明:与常规公交车相比,该并联混合公交车节省燃料消耗15%～40%。
To make hybrid electric buses more efficient, a monitoring strategy has been developed that controls the power distribution between the engine and the electric motor. The hybrid bus’s monitor optimizes fuel economy using such information as altitude, vehicle speed, and roadmap from a GPS receiver. Between the two power sources, the control algorithm uses the power allocation ratio (PSR). An optimal control scheme can be derived from the Power Distribution Ratio (PSR) curve derived from the kinetic programming theory. The results show that compared with conventional buses, the parallel hybrid buses save 15% -40% of fuel consumption.
