| 摘 要： | 汽车在高速行驶过程中进行超车或两车并列行驶时容易出现侧向碰撞。提出利用主动转向技术,根据两车并行时侧向距离的变化控制两车侧向距离满足安全要求,减小汽车发生侧向碰撞的可能。建立了基于两车侧向距离及其变化率的模糊-PID控制模型,确立了相应的控制策略和控制算法,设计了模糊-PID控制器,进行了复杂工况下的仿真试验,并将仿真结果与利用PID控制方法得到的仿真结果进行了对比。结果表明利用主动转向模糊-PID控制技术,能减少汽车在超车时发生侧向碰撞的危险,使汽车在高速行驶过程中具有更好的安全性。

| Abstract: | Automobiles are easy to be in side collision when in high speed overtaking or parallel driving.Based on the change of side distance between parallel automobiles,a control method by active steering technology was proposed.The method aimed to satisfy the safety demand of side distance and reduce the posibility of side collison.By active steering technology,the fuzzy-PID control model based on the side distance between automobiles and its change rate and the according control strategy was constructed,the fuzzy-PID controller was designed,and the simulation experiment under complex driving condition was carried out.The contrast of the simulation results with those from PID control showed that the technology of active steering fuzzy-DPID control can reduce the posibility of side collision and ensure better safety in high speed driving. |
