In order to avoid traffic accidents, the most fundamental method is to improve the cognitive ability and the reaction ability of human beings, and the basic method for improving the cognitive ability and the reaction ability of human beings is to use various tools, so that the prior vehicle which is not based on the internet of vehicles has a blind area warning function to indirectly improve the cognitive range of human eyes, and a brake auxiliary system is used to indirectly improve the human reaction ability. With the development of the car networking technology, various auxiliary technologies will make great progress. The invention provides a method for information transmission between a mobile terminal carried by a pedestrian and a vehicle-mounted mobile terminal so as to meet the needs of the prior art.
