Bidirectional broadcast type inter-vehicle communication system and method

Abstract

The invention discloses a bidirectional broadcast type inter-vehicle communication system and method. The system mainly comprises a wireless transceiver and an information processing device, the wireless transceiver comprises an antenna, a duplexer, a transmitter, a code modulator and a receiver, and the information processing device comprises a system controller, a information parsing processor, a broadcast information preprocessor, a ranging processor, a vehicular system interface, a sensor interface, a display and position interface and an information processing center. The method includes the technical processes of broadcasting vehicular information outwards, receiving broadcast information of adjacent vehicles in real time, measuring relative distance of front and back vehicles within communication distance, warning the surrounding vehicles within a certain distance range, transmitting warning information to subsequent vehicles and receiving passed vehicle broadcast information in real time. By the system and method, functions of collision-avoidance warning, traffic information rebroadcasting, traffic intersection information statistics and the like are realized effectively, and traffic accident occurrence rate is lowered.

Description

technical field [0001] The invention belongs to the technical field of inter-vehicle information communication, and in particular relates to a two-way broadcast inter-vehicle communication system and method. Background technique [0002] With the development of the automobile industry, the number of domestic automobiles is increasing day by day, and the problems of safe driving of automobiles and dynamic monitoring of road conditions have become increasingly prominent. At present, automobile safety measures include measures such as improving vehicle braking performance, improving vehicle protection capabilities, improving the performance of automotive lighting facilities, and installing anti-collision radar facilities. These measures have relatively large limitations and high costs. The protective performance deteriorates or the protective measures are limited under adverse weather conditions such as at night, and it is difficult to achieve effective warning of the following...
