Vehicular Collision Avoidance Warning System

Features

With Linux operating system into embedded circuit board. The positioning unit is used to provide the position and heading information from GPS module; furthermore, the vehicular unit is used to receive the break, throttle, and other signals via Controller Area Network (CAN) interface which connected to each mechanism. From the position data and vehicular information, the VCAWS provided a conflict detection algorithm to do time separation and remote warning with error bubble consideration. The proposed system is carried out and verified with theoretical application, hardware integration and schematized tests in several kinds of scenarios, moreover, the warning information is also on-line displayed and used as a driving map in the screen. This system is able to enhance driver assistance service and realize critical safety by using vehicular information from the neighbor vehicles.
