Compared with the prior art, the invention has the following advantages: traffic safety is always a very important concern of all countries, and developed countries struggle to ensure the safety of pedestrians and non-motor vehicles through strict legislation in order to ensure the traffic safety. However, even if the law is strict, a lot of drivers still hold lucky psychology, the authoritative party cannot timely know and stop illegal behaviors of the many drivers, and even if the drivers strictly obey the traffic rules, some sudden and nonpropriate dangerous behaviors of some pedestrians can also be direct causes of traffic accidents. In fact, the root cause of traffic accidents is the limitation of human cognition, if human beings have nearly infinite perception capability, the traffic accidents do not happen, and the accidents often happen in blind areas of driver attention and cognition because drivers cannot exceed the perception capability of human beings. In order to solve the problems of the prior art, the invention provides a pedestrian position information uploading method for a vehicle networking system, the method can timely acquire the position of a pedestrian, after the position of the pedestrian is acquired, a computer judges danger according to the relative position of the pedestrian and a vehicle, and if the danger occurs, a server can timely transmit alarm information to a mobile phone carried by the vehicle and/or the pedestrian, so that the cognitive ability of human beings can be extended to the maximum extent, and the accident occurrence probability is reduced.
