Driving assistant system based on ITS

Kalman filter and χ~2 method are used to the design of the radar signal processing algorithm and so to a scanning laser radar on vehicle. Based on the data of 40 drivers, a safety distance model considering driver behavior is set up. Taking the driver behavior and vehicle dynamics into account, two layers control system is used to design the safety distance control system. Based on the above work, a driving assistant system is set up. It has the functions of keeping safety distance, automatic stop and go, and forward collision avoidance. The steady distance error is smaller than 1 m and the steady velocity error is smaller than 1.5 m/s.
