基于舒适性考虑的AEB仿真测试

AEB Simulation Test Based on Comfort

自动紧急制动系统作为一项重要的汽车主动安全技术,能够辅助驾驶员避免车辆纵向碰撞。为进一步对自动紧急制动系统进行优化,基于Honda算法建立了考虑驾驶员反应时间和驾乘者舒适性条件的优化模型,并与原有算法进行对比。研究结果表明,优化后的模型能够在有效实现碰撞避免的基础上,与前车保持更加合适的距离,在部分工况下的初始制动时刻更晚,对驾驶员的干扰更小,基本满足驾乘者的舒适性要求。

As an important vehicle active safety technology, automatic emergency braking system can assist the driver to avoid longitudinal collision. In order to further optimize the automatic emergency braking system, an optimization model considering the reaction time of the drivers and the comfort of the drivers and passengers was established based on Honda algorithm, and the Honda algorithm was compared with the original algorithm. The results show that the optimized model can keep a more appropriate distance from the front vehicle on the basis of effectively avoiding collision.The initial braking time is later under some working conditions, and the interference to the drivers is less, which basically meets the comfort requirements of the drivers and passengers.
