Abstract:

In order to provide more reference for the unmanned vehicle, an intelligent electric vehicle was designed. This intelligent electric vehicle was composed of MC9S12XS128 microcontroller as the master chip,camera and wireless module, etc. The master chip analyzed the information collected from camera and drove the motor running with PID（Proportion Integration Differentiation） control strategy, which made the intelligent electric vehicle automatically run on the single track and the medium line of the double track, and automatically avoid obstacle. The intelligent electric vehicle exchanged the information with the target by using wireless module, which made the intelligent electric vehicle cast laser spot on the center of the target in the course of driving by adjusting the steering gear. Shooting scores was high, and the result of the experiment was satisfactory.

Key words: automatic control technology, intelligent electric vehicle, proportion integration differentiation (PID) control, wireless data communication module
