The invention provides a running control method for a distributed permanent magnet eight-drive electric monorail crane. The problem that precise control over all driving parts cannot be achieved through manual operation of an existing monorail crane is solved. According to the device, the motor rotating speed, the maximum demanded power and the demanded torque of a vehicle are obtained through a vehicle-mounted sensor of a detection unit and vehicle parameters; the detection unit is connected with the control processing unit through a CAN bus, and the control processing unit establishes a torque distribution model based on the acquired sensing data, determines the torque distribution coefficient of each driving part motor, and calculates the maximum working efficiency of the driving system and the braking system at the moment; the control processing unit is used for judging signals of the control unit through a vehicle control unit, a central processing unit formulates a vehicle control strategy with the maximum working efficiency and energy saving of a driving and braking system as the control target on the basis of a torque distribution model, and the strategy dynamically and accurately distributes torque of all driving parts according to different working conditions. According to the invention, the torque of each driving part is accurately distributed under all working conditions, the safe operation of the monorail crane is ensured, and the energy loss is reduced.
