The embodiment of the invention discloses a position relationship determination method and device, a storage medium and equipment, and is used for accurately determining the position relationship between a lane where a target vehicle is located and a lane where surrounding vehicles are located so as to accurately analyze potential collision risks possibly existing between the vehicles. The methodprovided by the embodiment of the invention comprises the steps that the device comprises a processor, the method comprises the following steps: acquiring target position information of a target vehicle which is recently greater than or equal to three times; fitting a first straight line, then, according to the obtained current target position information of the surrounding vehicles of the targetvehicle; determining position information of an intersection point which passes through surrounding vehicles and is perpendicular to the first straight line; then, the distance between the intersection point and the surrounding vehicles is determined according to the position information of the intersection point and the current target position information of the surrounding vehicles, and then theposition relation between the lane where the target vehicle is located and the lane where the surrounding vehicles are located can be accurately determined according to the distance.
