Research on intelligent vehicle high-speed steering control based on CCD sensor

This paper presents the intelligent vehicle´s highspeed steering control model based on CCD sensor, to ensure that the vehicle pass the curve stably and rapidly, and do not runaway. First, the vehicle obtain road information by CCD visual sensor, and detect the type of road and the location of the vehicle etc. Second, calculate the turning radius of the road in front of the vehicle. Third, figure out the vehicle´s highest speed and servo´s steering angle through turning mathematical model, establish the relationship between turning radius and speed, turning radius and steering angle. Then, in order to make the vehicle achieve the target speed quickly and stably, some mathematical analysis of the driving motor has been done, and the relationship between speed and motor´s armature voltage is established. Finally, verify and calibrate the turning mathematical model experimentally. The result shows that the model algorithm is stable and accurate, and the intelligent vehicle can pass different types of road with high and stable speed.
