摘要
汽车主动防撞控制技术有利于提高汽车的主动安全性,控制器根据安全车距和路况实时控制制动强度,优先保证汽车的安全性,并尽可能地保证驾驶舒适性。本文建立了CarSim仿真平台,基于主动防撞系统最优控制器,在低速和高速同向跟随行驶工况下对主动防撞系统最优控制器进行仿真。仿真结果表明,低速和高速同向跟随情况下,控制器主动防撞控制效果明显,自车减速适当,系统能够满足行车过程中自车与前方行车安全距离的要求,兼顾汽车的驾驶舒适性。
Automobile active safety is improved with anti-collision technology. According to safety distance and road condition, the braking strength is controlled to insure automobile safety, and driving comfort as far as possible. Simulation platform of CarSim is established in this paper, and then the controller of active anti-collision system is simulated with low-speed and high-speed flowing condition based on the optimal control theory. The simulation results show that the active anti-collision controller of system is effective, the controlled automobile speed decreases rightly, the control system gives the safe distance between controlled automobile and front automobile, giving consideration of driving comfort.
