The invention discloses a power control method suitable for a hybrid commercial vehicle, relates to the field of new energy vehicles, and solves the problems that according to an existing hybrid powervehicle control scheme of the commercial vehicle, due to the working conditions of frequent starting and stopping, low-speed driving and the like, the fuel consumption rate is high and the like. According to the method, motor driving is adopted in working conditions such as starting and low-speed low accelerator. In high-speed large accelerator working condition, an engine and a motor are jointlyadopted for driving, and through a reasonable energy recovery strategy, oil consumption is obviously reduced compared with an existing control scheme. The fuel consumption is effectively reduced by reasonably controlling the start and stop of the engine. Starting and stopping are reasonably controlled by detecting the SOC of a power battery, the vehicle speed, the air pressure of a brake air chamber, the voltage of a storage battery and other relevant parameters of starting and stopping of an engine, and the idling oil consumption ratio is reduced on the premise that the dynamic property andsafety of the whole vehicle are guaranteed. According to the method, by reasonably distributing the power source, the fuel consumption rate during starting and low speed is reduced.

    一种适用于混合动力商用车动力控制方法,涉及新能源汽车领域,解决现有商用车的混动车控制方案,由于存在频繁起停以及低速行车等工况,燃料消耗率较高等问题,本发明通过优化控制方案,在起步、低速小油门等工况采用电机驱动,高速大油门采用发动机和电机共同驱动,并通过合理的能量回收策略,油耗相较于现有控制方案有明显降低。通过合理控制发动机启停,有效减少燃料消耗。通过检测动力电池SOC、车速、制动气室气压、蓄电池电压等和发动机启停相关参数,合理控制发动启停,确保在整车动力性以及安全的前提下减少怠速油耗占比。本发明所述的方法通过合理分配动力源,降低起步和低速时的燃油消耗率。
