The invention discloses a high-precision fitting method of a motor MAP and application thereof. The motor MAP is made based on a motor efficiency fitting value output by a trained BP neural network; the BP neural network training method comprises the following steps: taking actual motor efficiency values of a motor at different rotating speeds and torques as samples to train the BP neural network, so that an error between a motor efficiency fitting value obtained through the BP neural network and the actual motor efficiency value is within a preset error range; according to the method, the motor efficiency fitting value output by the BP neural network is used as a data basis, a high-precision motor MAP can be obtained, and a reliable and stable data basis is provided for a vehicle modular multi-phase motor to realize an optimal efficiency algorithm.
