The embodiment of the invention provides an oil-cooled electrically-driven oil pump control strategy and system, and belongs to the technical field of automobiles. The control strategy comprises the steps that the working states of a low-voltage power source and a high-voltage power source are determined; under the condition that the working states of the low-voltage power supply and the high-voltage power supply are starting states, determining a gear mode of the automobile; and an oil pump system is controlled and adjusted according to the gear mode of the automobile. And the gear mode of the automobile is determined, and control strategies of the oil pump rotating speed needed by lubrication and cooling of the oil cooling motor system in different working modes are set. On the basis of the actual working condition of the whole vehicle and heat dissipation and cooling of the motor, the oil pump is subjected to refined control according to the efficiency requirement, the NVH requirement and the heat dissipation and lubrication requirement of the whole vehicle, the oil pump control strategy meets the lubrication and cooling requirements, meanwhile, the efficiency of the system is improved, the NVH performance is improved, the energy consumption of the oil pump is reduced, and the service life of the oil pump is prolonged. And the endurance mileage of the battery is improved.
