摘要
交通拥堵辅助作为一种高级驾驶辅助系统,对缓解和减轻交通拥堵状态下驾驶员的疲劳具有重要作用。在交通拥堵状态下,车辆会频繁地进行加减速动作,保持合适的跟车距离对交通拥堵状态下的安全性和驾驶体验尤为关键。文章首先分析了交通拥堵辅助系统的跟车性能要求;其次,通过简化跟车过程和理论推导,建立了交通拥堵辅助系统跟车模型;最后,通过实车试验验证了交通拥堵辅助系统跟车模型的合理性和适用性。
As an advanced driver assistance system,traffic jam assistant system plays an important role in easing driver fatigue in traffic jam. Vehicle is accelerated and decelerated frequently in traffic jam status,so maintaining a proper car following distance is critical to the safety and driving experience. Firstly,the car following performance requirement of traffic jam assistant system is analyzed.Then,the car following model of traffic jam assistant system is established by simplifying the following process and theoretical derivation. Finally,the rationality and applicability of car following model are verified by vehicle test.
