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.

    本申请属于智能交通技术领域,具体涉及终端定位方法、装置、碰撞预警系统及电子设备。该方法应用于车联网终端,包括:接收直连通信PC5消息;当确定所述PC5消息为目标路侧单元发送的消息时,激活定位模块进行定位,并在移动过程中根据当前终端位置采用不同的定位模式进行定位;其中,所述定位模式的定位精度随所述当前终端位置和碰撞易发区域之间的距离减小而增大,并随所述距离增大而减小。本申请能够提高定位精度,并降低功耗,延长车联网终端的续航时间。
