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.
