The invention relates to the technical field of motor driving control, in particular to a multi-motor cooperative driving and
torque distribution method and
system, and the method comprises the steps: collecting motor rotating speed, current, battery SOC and whole
vehicle driving condition data in real time, carrying out the preprocessing of the collected multi-
source data, eliminating the
noise interference, and carrying out the
signal feature extraction; a torque demand model is established based on
vehicle driving condition classification, and the target torque of the whole vehicle is calculated; constructing a
torque distribution model fusing working condition weights, combining
motor efficiency characteristics, a battery SOC state and
road condition resistance, and dynamically distributing the torque of each motor through an improved
particle swarm optimization algorithm; and the state of the motor is monitored in real time in the driving process,
torque distribution data of this time is input into a
database after the vehicle is driven, and the torque demand model and torque
distribution model parameters are optimized. Through working condition identification, intelligent
algorithm distribution and dynamic optimization, the
driving safety of the electro-tricycle and the driving efficiency of the motor are improved.
