The invention discloses a hybrid power vehicle driving control method and system, and aims to provide a solution capable of coordinating the driving demand of a hybrid power vehicle and the electric quantity of a power battery. The vehicle comprises a first motor, a power battery, a second motor, a first drive axle and a second drive axle. The method comprises the steps that the state of charge (SOC) and the running speed of a power battery in the running process of a vehicle are obtained, and a peak driving parameter value capable of being provided by a second motor is determined according to the running speed; if it is determined that the SOC is larger than or equal to the first SOC value, a first motor is controlled to drive a first drive axle; if it is determined that the SOC is smaller than the second SOC value, the first motor is controlled to generate electric energy and output the electric energy to the power battery; and if it is determined that the SOC is larger than or equal to the second SOC value and smaller than the first SOC value, and the total driving parameter demand value of the vehicle is larger than the peak driving parameter value, the first motor is controlled to drive the first drive axle.
本申请公开了一种混合动力车辆驱动控制方法及系统,用以提供一种可以协调混动车辆的驱动需求和动力电池电量的解决方案。所述车辆包括第一电机、动力电池、第二电机、第一驱动桥和第二驱动桥。所述方法包括:获取车辆在运行过程中的动力电池的荷电状态SOC和运行车速,及根据运行车速确定第二电机可提供的峰值驱动参数值;若确定SOC大于或等于第一SOC值,控制第一电机对第一驱动桥进行驱动;若确定SOC小于第二SOC值,控制第一电机产生电能并输出给动力电池;若确定SOC大于或等于第二SOC值、小于第一SOC值,且车辆的总驱动参数需求值大于峰值驱动参数值,控制第一电机对第一驱动桥进行驱动。
