The invention provides a torque distribution control method and system for a distributed driving vehicle. The control method comprises the steps: obtaining driving information of a vehicle driver, driving information of a vehicle, and road surface information of a vehicle driving road surface in real time; obtaining a driving intention of the vehicle driver according to the driving information; obtaining a driving condition of the vehicle according to the driving intention; setting a control function of vehicle torque distribution corresponding to the driving working condition; and adopting aparticle swarm optimization algorithm to distribute the vehicle torque according to a control function, the driving information, the running information and the road surface information so as to control a wheel driving motor of the vehicle. Optimal driving energy efficiency torque distribution control of the vehicle can be achieved on the premise that the stability of the vehicle is ensured so that energy saving performance of the distributed driving vehicle can be improved, and meanwhile, the method and the system can be suitable for vehicles of which front and rear axle wheels are provided with driving motors of different configurations, and have relatively wide adaptability.
