A vehicle active anti -collision system is presented in this paper, in which its working principle is introduced, and its anti-collision control is studied. Firstly the safety distance model is analyzed according to vehicle kinetic theory. And vehicle longitudinal and lateral safety distance model which include safety critical distance, lock-in target distance, danger critical distance and limit critical distance are established. Then the danger targets are identified and classified based on safety distance model. Finally, the corresponding danger-prevention control strategy is established according to different degrees of danger.
