The invention belongs to the technical field of intelligent transportation, and particularly relates to a terminal positioning method and device, a collision early warning system and electronic equipment. The method is applied to an Internet of Vehicles terminal, and comprises the following steps: receiving a direct communication PC5 message; when it is determined that the PC5 message is a message sent by a target road side unit, activating a positioning module to perform positioning, and performing positioning by adopting different positioning modes according to the current terminal position in the moving process; wherein the positioning precision of the positioning mode is increased along with the decrease of the distance between the current terminal position and the collision-prone area, and is decreased along with the increase of the distance. According to the invention, the positioning precision can be improved, the power consumption is reduced, and the endurance time of the Internet of Vehicles terminal is prolonged.
