The invention discloses a starting control method and device of an electric hybrid system, a vehicle and a computer storage medium. The starting control method comprises the steps that real-time vehicle state parameters and battery state parameters are obtained; according to the vehicle state parameter and the battery state parameter, determining whether the battery discharge capacity is surplus or not; and if it is determined that the discharging capacity of the battery is surplus, the engine is controlled to be started in the air-fuel ratio closed-loop state according to the corresponding first high-voltage starting mode. By the adoption of the technical scheme, oil consumption and emission of the high-pressure starting mode of the electric hybrid system can be reduced, and NVH generated when the engine is started is optimized.

    本申请公开了一种电混系统的启动控制方法、装置、车辆及计算机存储介质,通过获取实时的车辆状态参数和电池状态参数;根据所述车辆状态参数和所述电池状态参数确定电池放电能力是否富余;若确定所述电池放电能力富余,则按照对应的第一高压启动模式控制发动机在空燃比闭环状态下启动。采用本申请技术方案能够降低电混系统的高压启动方式的油耗和排放,以及优化发动机启动时的NVH。
