The invention relates to the technical field of hybrid electric vehicle control, and discloses a hybrid electric commercial vehicle energy management method based on intelligent network connection information, the current power demand P0 of the whole vehicle is calculated according to the accelerator opening degree and the vehicle speed of a driver, and mode judgment including a pure electric mode, a pure engine mode and a hybrid mode is performed in combination with the SOC of a power battery. The method comprises the following steps: acquiring engine required power PE0 and motor required power PM0, acquiring gradient information and traffic light information through intelligent network connection information, performing fuzzy logic control based on the gradient information and the traffic light information, determining an engine power correction coefficient lambda, and calculating to obtain final engine required power PE1 = PE0 * lambda and final motor required power PM1 = P0-PE1. According to the hybrid power commercial vehicle energy management method based on the intelligent network connection information, the vehicle is controlled in real time, the working point efficiency of the engine is improved, and the energy consumption of the whole vehicle is reduced.
本发明涉及混合动力汽车控制技术领域,公开了一种基于智能网联信息的混合动力商用车能量管理方法,根据驾驶员的油门开度和车速计算整车当前的功率需求P0,结合动力电池SOC进行模式判断,包括纯电模式、纯发动机模式和混动模式,获得发动机需求功率P_E0和电机需求功率P_M0,通过智能网联信息获取坡度信息和红绿灯信息,基于坡度信息和红绿灯信息进行模糊逻辑控制,确定出发动机功率校正系数λ,计算得到最终发动机需求功率P_E1=P_E0*λ,最终电机需求功率P_M1=P0‑P_E1。本发明基于智能网联信息的混合动力商用车能量管理方法,实时对车辆进行控制,提升了发动机的工作点效率,降低了整车的能耗。
