The invention discloses a control algorithm constructed based on a characteristic path of a main positioning point in a parking lot and a system thereof, and belongs to the technical field of intelligent vehicle decision making. The method comprises the following steps: establishing a gate main positioning point according to the gate position; acquiring trunk road intersection positions according to road network data, establishing road main positioning points, uniformly dividing roads according to lengths, and establishing a road positioning point diagram; obtaining parking space information according to the road network data, and dividing parking spaces into different types of parking space areas according to the sizes of the parking spaces; classifying the vehicles according to the wheelbase sizes of the vehicles, and then selecting one idle parking space as a parking end point; and planning a shortest path from a starting point to an end point according to the established road positioning point diagram by adopting an A * algorithm. According to the control algorithm and system adopted by the invention, the positioning problems of vehicles and tracks in the parking lot and rapid selection of proper parking spaces for the vehicles are solved, the accurate control of the vehicles in the parking lot is realized, and different parking spaces can rapidly correspond to different vehicles for positioning and parking.
