The invention discloses an AEB-P system based on a vehicle working condition variable control strategy, and the system obtains the surrounding environment and pedestrian information of a vehicle through an information perception module, and carries out the matching and fusion of the surrounding environment and pedestrian information through a data fusion module, and obtains the data of pedestrians in front of the vehicle. The driving condition judgment module judges the driving condition of the current vehicle; the control strategy calculation module receives driving conditions of the vehicle and data of pedestrians in front of the vehicle; outputting a TTC grading threshold value according to the pedestrian data in front of the vehicle and the driving condition; the risk assessment decision module calculates a TTC value according to the TTC grading threshold value and the data of pedestrians in front of the vehicle, and decides a current risk grade; and the control execution module controls the vehicle according to the current risk level. The triggering threshold value of the AEB-P system continuously changes according to the current driving state of the vehicle, the situation that the AEB-P system fails due to some driving states under the fixed threshold value can be effectively avoided, meanwhile, the triggering threshold value is evaluated and corrected, and interference of the AEB-P system to a driver is reduced while the effectiveness of the AEB-P system is guaranteed.

    本发明公开了一种基于车辆工况可变控制策略的AEB‑P系统,通过信息感知模块获取车辆周围环境与行人信息,数据融合模块将周围环境与行人信息进行匹配融合得到车辆前方行人数据;行驶工况判断模块判断出当前车辆的行驶工况;控制策略计算模块接收车辆的行驶工况和车辆前方行人数据;根据车辆前方行人数据与行驶工况输出TTC分级阈值;风险评估决策模块根据TTC分级阈值和车辆前方行人数据计算出TTC值,并决策出当前风险等级;控制执行模块根据当前风险等级对车辆执行控制。本发明的AEB‑P系统的触发阈值根据车辆当前行驶状态不断变化,可以有效避免固定阈值下某些行驶状态导致AEB‑P系统失效的情况,同时对触发阈值进行评价和修正,在保证AEB‑P系统有效性的同时减少AEB‑P系统对驾驶员的干扰。
