The invention belongs to the technical field of electric vehicle driving motor cooling, and particularly relates to a driving motor oil cooling system control method and device, a driving motor oil cooling system, a vehicle and a storage medium. In the driving motor oil cooling system, the driving motor oil cooling system comprises a driving motor and an oil pump motor, a stator and a rotor are arranged in the driving motor, the driving motor and the oil pump motor are connected through an oil way, and the method comprises the steps that whether the oil pump motor is over-temperature or not is detected; setting an oil pump motor temperature threshold, and controlling a power limiting flag bit according to the oil pump motor temperature; and determining the output rotating speed V of the oil pump motor according to the condition of the power limiting flag bit. According to the specific working condition of the oil pump motor, the output rotating speed of the oil pump motor is correspondingly adjusted, so that the oil pump motor works normally, and the safety of an oil pump cooling system is improved.
