Design of the Intelligent Vehicle System Based on CCD Camera

Abstract:

In the context of the session of the freescale Intelligence Car Competition, this paper designed the intelligent vehicle system based on MC9S12XS128 microcontroller and its mechanical system considering the driving-stability and comfort of car module. In the system, CCD camera gathers real-time track road conditions information, and then the microcontroller will identify road situation and realize tracking control with these information. Using time-optimal to control the DC motor speed and the positional PID to control the steering gear, adjust PID parameters dynamically based on the position of the black line. These measures guarantee the intelligent vehicle travel along a specified route safely、smoothly and fast, and then realize automatic tracing. The results show that the system meets the need of path recognition and anti-interfere well.
