The invention relates to a vehicle positioning and automatic vehicle release control method and system and base stations. The method comprises the steps that an entrance and an exit of a customs barrier are each provided with one base station, and the distance between the base stations is larger than the width of a lane; an electronic tag is arranged on a vehicle to be tracked and communicated with the base stations when the vehicle is driven into the range of the base stations; according to the distance between the base stations, the width of the lane and the numerical relationship between the width of the lane and the distance between the base stations, when the vehicle is driven into the range of the base stations, the distance between the electronic tag of the vehicle and the base stations is worked out on the basis of an arrival time difference algorithm, and therefore the current position of the vehicle is determined. The vehicle positioning and automatic vehicle release control method has the advantages that the two base stations are adopted, the vehicle can be positioned by adopting the algorithm based on the arrival time difference by means of position information of related fixing equipment of the customs barrier, and therefore whether the vehicle can be automatically released or not is determined according to the positioning result of the vehicle.
