| Abstract: | Aiming at the traffic safety,a warning system for automobile collision avoidance based on virtual instrument is designed.The design method of the system and test data are given simultaneously.The procedure is designed by LabVIEW7.0.The system adopts FMCW radar sensor and high-quality data acquisition board.This system can monitor the distance and velocity forward vehicle.It can give the alarm when the collide danger is predicted,and it can assist the driver to brake control,thus some collide accidents will be avoided.The effectiveness of the designed system is verified by some real tests. |
