The invention relates to a planetary gear noise control method and device, computer equipment, a storage medium and a computer program product. The method comprises the steps that under the conditions that the vehicle running state detected in real time is a parking state, the engine rotating speed is an idling rotating speed, and the environment temperature is smaller than a preset temperature threshold value, torque corresponding to the environment temperature serves as initial torque, a generator is controlled to conduct torque output with the initial torque, and first vibration acceleration is obtained; under the condition that the first vibration acceleration is larger than a preset acceleration threshold value, the initial torque is adjusted according to the first vibration acceleration, and an adjusted target torque is obtained; controlling the generator to perform torque output with the target torque to obtain a second vibration acceleration; and determining a noise reduction torque based on a comparison result of the first vibration acceleration and the second vibration acceleration, and controlling the generator to perform torque output by the noise reduction torque. The method can reduce the noise of the planetary gear.
