Abstract
The present disclosure relates to the field of noise reduction technologies, and specifically a motor noise control method and apparatus, a computer device and a storage medium are provided. The method includes: determining a current driving mode of a vehicle and a total torque required by the vehicle in the current driving mode; acquiring an electric drive noise distribution matrix of the vehicle in the current driving mode, where the electric drive noise distribution matrix includes correspondences among target motor noises, target motor speeds, and target motor torques of respective motors in the current driving mode; and distributing a torque of each motor according to the electric drive noise distribution matrix, where a sum of torques of respective motors is equal to the total torque required by the vehicle.
