In this paper, we proposed a real-time, vehicle-following system based on artificial landmark tracking and longitudinal/lateral vehicle control through landmark movement. The proposed autonomous vehicle system is designed to follow a human-driven lead vehicle accurately by tracking and following an artificial landmark. It is possible to measure the relative distance and the lateral motion of the lead vehicle based on the size and the trajectory of the pre-defined artificial landmark. An artificial landmark tracking algorithm was designed by using the Cam-Shift and Kalman-Filter methods to mimic real-time processing and actual vehicle driving situations. The kinematic bicycle model was used to control the following vehicle. Based on this model, longitudinal and lateral tracking control algorithms were proposed. To evaluate the performance of the proposed vehicle system, a commercial micro electric car was modified with an autonomous driving system. A driving test was carried out on the Ochang proving ground at Chungbuk National University. The artificial landmark detection performance was calculated at 97.76 % under outdoor driving conditions. The distance from the lead vehicle was calculated by using the GPS sensor. We propose a distance calculation system by integrating the GPS sensor distance with the artificial landmark distance. Stability was added by comparing the two data sets. By using this system, we propose an approach to correct other manual-driven vehicles cutting in front of the following vehicle. Vehicle tracking was successful by utilizing the tracking method, even with detection failures. Our system showed that another vehicle could be driven while maintaining a safe distance from the lead vehicle.
