The invention relates to the technical field of auxiliary driving, in particular to an emergency braking control strategy based on a safe distance model. Comprising two-vehicle relative distance interval division, a safety distance model, driver reflection time modeling and danger grade division, the sensing, decision making and control process in the working process of the AEB system is covered, and in the process of dividing the two-vehicle relative distance interval, in order to reduce damage to a driver caused by too large braking strength, the safety distance model is provided for the driver. The relative distance between two vehicles is divided into four intervals, the driving style and braking comfort of a driver are considered under the condition that safety is guaranteed when a safety distance model is established, the parking safety distance and the braking deceleration during graded braking are reasonably set, and the influence of the speed on the driver is considered in the process of modeling the response time of the driver; according to the invention, the safety, comfort and difference of the emergency braking system during working are fully considered.

    本发明涉及辅助驾驶技术领域,具体涉及一种基于安全距离模型的紧急制动控制策略;包括划分两车相对距离区间、安全距离模型、驾驶员反映时间建模、危险等级划分,涵盖了AEB系统工作过程中的感知、决策与控制过程,在划分两车相对距离区间的过程中,为减少制动强度过大对驾驶员造成的伤害,将两车相对距离划分为四个区间,在建立安全距离模型时在保证安全的情况下兼顾驾驶员驾驶风格及制动舒适性,对停车安全距离、分级制动时的制动减速度进行合理设置,在对驾驶员反应时间建模的过程中考虑速度对其的影响;本发明充分考虑了紧急制动系统工作时的安全性、舒适性及差异性。
