The invention relates to a hybrid electric vehicle driving method and device, computer equipment, a storage medium and a computer program product. The method comprises the steps that firstly, the hybrid electric vehicle is controlled to enter a pure electric mode according to an accelerator pedal opening signal, then the pure electric equivalent fuel consumption rate is determined according to the historical average fuel consumption rate of an engine, and then the series equivalent fuel consumption rate is determined according to the power generation electric quantity and the required electric quantity of a generator; controlling the hybrid electric vehicle to enter a series connection mode according to the pure electric equivalent fuel consumption rate and the series connection equivalent fuel consumption rate, determining a parallel connection equivalent fuel consumption rate according to the engine direct drive energy and the vehicle driving demand energy, and finally determining the hybrid electric vehicle according to the series connection equivalent fuel consumption rate, the parallel connection equivalent fuel consumption rate, the current vehicle speed and the target vehicle speed. And controlling the hybrid electric vehicle to enter a parallel mode. According to the method provided by the invention, switching among different driving modes of the hybrid electric vehicle can be accurately realized according to the pure electric equivalent fuel consumption rate, the series equivalent fuel consumption rate and the parallel equivalent fuel consumption rate.

本申请涉及一种混合动力汽车驱动方法、装置、计算机设备、存储介质和计算机程序产品。所述方法包括：首先根据油门踏板开度信号，控制混合动力汽车进入纯电模式，然后根据发动机历史平均油耗率，确定纯电等效油耗率，再然后根据发电机发电电量和需求电量，确定串联等效油耗率，接着根据纯电等效油耗率和串联等效油耗率，控制混合动力汽车进入串联模式，再接着根据发动机直驱能量和车辆行驶需求能量，确定并联等效油耗率，最后根据串联等效油耗率、并联等效油耗率、当前车速以及目标车速，控制混合动力汽车进入并联模式。本申请提供的方法，根据纯电等效油耗率、串联等效油耗率以及并联等效油耗率能够精准实现混合动力汽车不同驱动模式间的切换。
