The invention discloses a driving method and device for unmanned driving equipment. The driving method for the unmanned driving equipment comprises determining a target turning circle radius accordingto an expected path, position information of the unmanned driving equipment and existing attributes of the unmanned driving equipment, and adjusting a driving direction and driving speed of the unmanned driving equipment according to the target turning circle radius. In the driving method, the target turning circle radius is determined by a plurality of physical quantities during the driving of the unmanned driving equipment, and the driving of the unmanned driving equipment is adjusted according to the target turning circle radius, so inadequate adjustment accuracy can be solved when deviation distance is the only factor to be adjusted and the unmanned driving equipment drives toward a direction to reduce the deviation distance; therefore, the unmanned driving equipment can be well controlled to drive on the expected path and safety accidents during the driving process can be reduced, so the unmanned driving system can be suitable for complicated road conditions and fast driving speed.
