The invention discloses a method and system for enabling an unmanned vehicle to enter a parking space, and the method comprises the steps: setting a plurality of ZigBee modules on parking spaces in advance, and setting a plurality of ZigBee modules on the unmanned plane; calculating the distances from the plurality of ZigBee modules on the unmanned plane and the plurality of ZigBee modules on parking spaces when the unmanned plane enters the ZigBee coverage of the parking spaces, controlling and adjusting the direction of the vehicle according to the distances, and enabling the central axis of the vehicle to be approximately overlapped with the central line of the parking space; controlling the vehicle to move straightly to enter the parking space. The ZigBee positioning technology is employed assisting the unmanned plane to enter the parking space, thereby effectively avoiding the impact from the environment factors, guaranteeing the correctness of navigation data, achieving the functions of backing up a vehicle to enter the parking space and avoiding the obstacles, and bringing great convenience.
