汽车主动防撞系统的规避控制研究

Research on Active Control of Vehicle Anti-collision System

提出了一种汽车主动防撞系统,介绍了该防撞系统的工作原理,并对其规避控制进行了研究。依据汽车运动学理论对安全车距模型进行了分析,建立了包括安全临界、锁定目标、危险临界和极限临界的汽车纵向安全车距模型以及横向安全车距模型;结合安全车距对危险目标进行识别和分类;针对不同危险程度的目标制定了相应的规避控制策略。

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.
