The invention relates to a hybrid electric vehicle parallel mode power generation control method, device and equipment and a storage medium. The method comprises the steps that the actual charge state of a battery pack and the target charge state of starting power generation are obtained; determining a power generation level according to a difference value between the actual charge state and a target charge state, the power generation level being in positive correlation with an absolute value of the difference value; obtaining the whole vehicle demand torque of the vehicle based on the whole vehicle dynamics model; the output torque of an engine is determined according to the power generation level and the whole vehicle demand torque, the output torque is larger than the whole vehicle demand torque, and the exceeding amount of the output torque relative to the whole vehicle demand torque is in positive correlation with the power generation level; according to the difference value torque of the output torque and the whole vehicle demand torque, a driving motor is driven to generate electricity in the parallel connection mode so as to supplement electricity to a vehicle battery, and by means of the method, the problem that in the prior art, the driving electricity protection capacity of the hybrid power vehicle in the parallel connection mode is poor is solved.
