The invention relates to a hybrid power vehicle engine output torque control method, a medium, a device and a vehicle, and aims to solve the problem that an engine is prone to flameout when a hybrid power vehicle starts to charge a high-voltage battery. The demand charging torque meeting the high-voltage battery charging demand and the demand power generation torque meeting the target load work of the hybrid power vehicle are calculated, so that the whole vehicle power generation torque of the engine is obtained, and the whole vehicle power generation torque is the sum of the demand charging torque and the demand power generation torque; calculating the minimum required power generation torque meeting the work of a first target load related to vehicle driving and safety in the target loads; and according to the required charging torque, the required power generation torque and the minimum required power generation torque, the power generation output torque of the engine is controlled to be increased to the whole vehicle power generation torque. Therefore, the risk that the engine is prone to flameout when the vehicle starts to charge the high-voltage battery can be reduced on the basis of ensuring the power performance of the vehicle.
