In the transportation monitor system
we set up the area of interest (AOI) of the vehicle model and adjust the size of AOI dynamically in order to track vehicle accurately. The results of experiment show that
motive vehicle detection by adopting digital image is one of key technologies. To detect motive vehicle accurately
the arithmetic proposed in the paper can suppress shadow availably
we establish an adaptive background updating model firstly. Noise is suppressed by using modality filter
detect motive vehicle accurately and satisfy real-time motive vehicle tracking. 2009 SPIE.
and we obtain binary image by using maximum entropy to choose dynamic adaptive threshold. Based on positive information of shadow and aspect feature of motive vehicle
we adopt HSV colour space and double threshold to solve the problem of vehicle shadow. According to prediction result of Kalman filtering

By combining visual preview kinematics
dynamic equation of steering system and 2-DOF steering dynamistic model of 4WS
it can easily attenuate the change and uncertainty of model. 2008 IEEE.
we establish the two degree of freedom model of four-wheel steering vehicle. And then the switching hyper plane is designed by applying the optimal control theory. During the change of parameter is little
4WS steering performance is carried out by adopting sliding variable structure controller. To improve the steering performance of 4WS
especially state variables convergent velocity
Kalman filter for 4WS is designed. And the robust optimal controller is designed for model and parameter is uncertainty. The simulation results show that the controller designed by the proposed method has good robustness

State observer design is one of key technologies in research field of intelligent vehicle. Experiment platform
visual guidance intelligent vehicle JLUIV-5
is establishedby Jilin University Intelligent Vehicle Group firstly. The system structure and assistant navigation control system
and different image identify algorithms to recognize preview path and stops for variable illuminations are introduced. The dynamic response equation of steering control system was got by system identification experiment. By combined with the preview kinematics model
and two-degree steering dynamic model of vehicle
the steering kalman filter mathematics model based on preview kinematics for intelligent vehicle was obtained. And observer is designed by applying steady Kalman filter theory. The simulation and experiment results
carry out in Jilin University Nanling Campus and Culture Center of Jilin Province
show that the image identify algorithms
and steady Kalmanstate observer designed by the proposed method has good adaptability for time-varying and parameters uncertain
it can satisfy intelligent vehicle trace the path reliably during outdoor experiment. 2008 IEEE.
