The invention relates to a driving control method of a hybrid vehicle in a series connection mode, a driving control device of the hybrid vehicle in the series connection mode, a storage medium and a control system. The driving control method for the hybrid vehicle in the series connection mode comprises the steps that according to a target vehicle speed range of the vehicle in the series connection mode, a corresponding driving demand power interval when the vehicle is driven to run in the target vehicle speed range is determined; according to the comprehensive efficiency distribution of the engine and the generator, based on a plurality of different driving demand powers in the driving demand power interval, determining a plurality of engine rotating speed values corresponding to the condition that the comprehensive efficiency of the engine and the generator exceeds a preset threshold value; selecting one engine rotating speed value from the plurality of engine rotating speed values as a target engine rotating speed value according to a target vehicle speed when the vehicle runs in the target vehicle speed range; the engine is controlled to work at the target engine rotating speed value to output the generated power to drive the vehicle to run, and the adjusting frequency of the engine rotating speed can be reduced to reduce fuel consumption.
本公开是关于一种混动车辆在串联模式下的行车控制方法、混动车辆在串联模式下的行车控制装置、存储介质及控制系统。该混动车辆在串联模式下的行车控制方法包括根据车辆在串联模式下行车时具有的目标车速范围,确定驱动车辆在目标车速范围下行驶时对应的驱动需求功率区间;根据发动机和发电机的综合效率分布,基于驱动需求功率区间内多个不同驱动需求功率,确定发动机和发电机的综合效率超过预定阈值所对应的多个发动机转速值;根据车辆在目标车速范围内行车时的目标车速,在多个发动机转速值中选择一个发动机转速值作为目标发动机转速值;控制发动机以目标发动机转速值工作输出发电功率驱动车辆行驶,可降低发动机转速的调整频率减少燃油消耗。
