The invention provides an energy output control method and system for an extended-range electric drive mining truck. The system takes the optimization of the energy consumption of the whole vehicle as a target, and dynamically adjusts the driving system to switch between an engine-generator set optimal efficiency mode and an engine optimal oil consumption mode by utilizing an energy output control method on the premise of meeting the dynamic property according to the vehicle speed, the acceleration information and the battery electricity storage value SOC which are acquired in real time; and real-time energy consumption adjustment of the whole vehicle under complex working conditions is realized. According to the designed energy output control strategy, complicated theoretical model calculation is not needed, strategy parameters only need to be adaptively adjusted according to driving battery parameters and engine parameters, strategy transplantation and engineering application are facilitated, and working condition adaptability and real-time performance are good.

    本发明提出一种面向增程式电传动矿用卡车的能量输出控制方法及系统。该系统以整车能耗最优化为目标,根据实时获取的车速、加速度信息和电池储电值SOC,在满足动力性的前提下,利用能量输出控制方法动态调整驱动系统在“发动机‑发电机组最优效率模式”和“发动机最优油耗模式”间切换,实现整车在复杂工况下的能耗实时调整。本发明设计的能量输出控制策略无需繁杂的理论模型计算,策略参数仅需要根据驱动电池参数和发动机参数进行适配调整,便于策略移植和工程化应用,工况适应性和实时性好。
