The embodiment of the invention discloses a network delay positioning error compensation method and device, and electronic equipment in the Internet of vehicles. The method comprises the steps of acquiring vehicle state information and transmission delay information, wherein the vehicle state information comprises vehicle position information, vehicle angle information and vehicle speed information; the vehicle angle information comprises the course angle and pitch angle of a vehicle; a direction vector is determined according to the vehicle position information and vehicle angle information;based on the direction vector, the vehicle speed information and transmission delay information, a displacement compensation value is determined; and the predicted position of the vehicle is determined according to the vehicle position information and the displacement compensation value. According to the technical scheme, the vehicle state information and the transmission delay information can becombined, the displacement compensation value can be determined, so that the correction of the vehicle position information can be achieved, the decrease of positioning accuracy caused by the networktransmission delay when the vehicle moves at high speed can be effectively avoided, and the driving security of the vehicle is improved.
Description
Technical field [0001] The present disclosure relates to the technical field of vehicle positioning, and in particular to a method, device and electronic equipment for compensating network delay positioning errors in the Internet of Vehicles. Background technique [0002] The Internet of Vehicles refers to the collection, storage and transmission of vehicle working conditions and static and dynamic information by installing on-board terminal equipment. The concept of Internet of Vehicles has brought more possibilities for future travel modes and lifestyles. [0003] In the process of proposing the present disclosure, the inventor found that in the Internet of Vehicles, there is inevitably a network transmission delay during the end-to-end transmission of data. For example, a self-driving vehicle can obtain its own position information through GPS equipment, and obtain the position information of other vehicles through the network to obtain the relative position between vehicles, t...
