Abstract

The invention discloses a vehicle-borne emergency call-for-help system and a call-for-help method thereof, which enable manual call-for-help and automatic emergency call-for-help for car accidents to be realized and belong to the technical fields of automotive electronics and communication. According to the system and the method, embedded and integrated navigation technology and communication technology are adopted so as to realize manual or automatic emergence call-for-help. Vehicle collision detection is carried out through vehicle motion information acquisition by an information acquisition device in the system and safety airbag ignition detection; then, collision information is transmitted to a central processing unit for processing; and processed data and pre-stored basic vehicle information are transmitted and received through a triple-redundancy method via short message, network and voice DTMF at most and reliable technologies such as non-normal termination decision, dual antennas and standby power supplies are adopted so as to improve the success rate and reliability of call-for-help and rescue. According to the system provided by the invention, an original vehicle is only modified a little, and the system is suitable for all vehicles and has a wide range of application.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and in particular relates to a highly reliable vehicle emergency call system and an automobile emergency call method. Background technique [0002] With the continuous increase of China's car ownership, road traffic accidents are also increasing, and car accidents have become an important cause of abnormal deaths. Therefore, the issue of road traffic safety has received more and more attention and attention.
