摘要: 本文中设计了一种基于个性化间距策略的自适应巡航系统多模式切换策略,以更好地适应实际驾驶工况并提高不同类型驾驶人的驾驶体验。首先,将ACC行驶模式划分为巡航、跟车、接管和换道4种工况,针对不同纵向工况,采用不同的间距策略,实现了稳定、可靠、适应驾驶人风格的工况间平滑切换。然后,通过两层分层控制策略实现自适应巡航系统多模式切换控制。最后,借助Matlab/Simulink与CarSim联合仿真开展巡航、跟车、接管、换道工况及混合切换工况试验。结果表明,设计的多模式切换控制策略效果良好,满足快速性、跟随性和舒适性的要求。

Abstract: A multi-mode switching strategy of adaptive cruise control system based on personalized spacing strategy is designed in this paper to better adapt to the actual driving conditions, and to improve the driving experience of different types of drivers. Firstly, the ACC driving modes are divided into four working conditions including cruising, car following, takeover and lane change. According to different longitudinal working conditions, different spacing strategies adapted to personalized driving style are adopted to realize stable, reliable, and smooth switching between different working conditions. Then, the multi-mode switching control of adaptive cruise control system is realized by two-layer hierarchical control strategy. Finally, the tests of cruising, car following, taking over, lane change and mixed switching conditions are carried out with the joint simulation of Matlab / Simulink and CarSim. The results show that the designed multi-mode switching control strategy is effective and meets the requirements of rapidity, following performance and comfort
