分析了国内外混合动力汽车控制策略的特点,针对ISAD系统各部件的特性和车用柴油机运行工况,以SOC值、车速、功率、油门踏板位置为主要控制参数,按照整车的运行状况,从燃油经济性和动力源的合理配合角度制定了不同的控制策略,并对该控制策略在不同工况下的实施情况进行了详细阐述和分析。
The features of the control strategy for hybrid electric vehicles both at home and abroad are analyzed. Aiming at the characteristics of each component of integrated starter alternator damper (ISAD) system with state of charge ( SOC), vehicle speed, power and the position of acceleration pedal as major control parameters, and based on the operation situation of complete vehicle, and from a point of view of the reasonable balance between fuel economy and power performance, different control strategies are formulated. And the implementations of the control strategy under different working conditions are described and analyzed in detail.
