Abstract:ABSTRACT:To improve the safety of adaptive cruise control system (ACC), experiment platform was built up. We obtained the movement state data of the host vehicle and vehicle ahead. Based on the distance between them, the lateral and longitudinal velocity, using Hidden Markov theory, we set up lane change intention prediction model of the vehicle ahead, which tested by the measured data. The results show that the prediction accuracy of the straight line section is 97% and in the curve section is 96%.
