混合动力摩托车动力性能匹配与控制策略

混合动力摩托车的研究是以嘉陵JL50QZC摩托车为平台,在其发动机主体结构不变的基础上,开发一套基于车速的直流无刷电机驱动和LPG发动机混合动力控制系统.本实验研究借助台架实验,优化出用于匹配混合动力的发动机控制参数,并由电机驱动力-阻力平衡图优化出用于匹配混合动力的电机控制参数,比较发动机与电机控制参数,得到混合动力摩托车控制策略和驱动切换速度点.通过道路实验,验证了控制策略的正确性和驱动切换的平稳性.

Driving Matching and Control Policy of Hybrid Motorcycle

Based on the Jialing Motorcycle JL50QZC,a series of hybrid control systems including the DC brushless moor and LPG engine relied on speed are developed without changing the major structure of the engine.Through the engine performance test,the control parameters of matching the hybrid engine have been optimized.The motor Driving Force-Resistance stable diagram is obtained by calculating,and thus the control parameters which match the hybrid motor is optimized.The control policy of hybrid motorcycle and the velocity point for driving switch by comparison of control parameters with electric engines are acquired.The validity of control policy and the stationarity of driving switch is verified via tests on roads.
