According to the relevant requirements of competition that carbon-free vehicle automatic obstacle avoidance, one item of the National Collegiate Engineering Training Competition, combined with the mechanical structure of ear, the control system was be designed, through the analysis of the real-time information that the distance between the vehicle and the curb plate of the track and the barrier, the velocity and angle of the vehicle, to make the carbon-free vehicle avoid obstacles automatically. The test results show that the control system can control of the vehicle to change direction stably...
