1. A motor noise control method, comprising:
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, wherein the electric drive noise distribution matrix comprises 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, wherein a sum of torques of respective motors is equal to the total torque required by the vehicle,
wherein an electric drive noise distribution matrix of the vehicle in a preset driving mode is established by:
acquiring test noises corresponding to each motor in the preset driving mode;
acquiring target motors of which test noises are greater than a preset noise;
determining the test noises of the target motors as target motor noises of the target motors; and
after acquiring target motor speeds and target motor torques corresponding to the target motor noises according to the target motor noises, establishing the electric drive noise distribution matrix,
wherein the preset driving mode comprises: a constant speed driving mode, an acceleration driving mode or a deceleration driving mode.
