The invention relates to the technical field of automobile active safety, and discloses an automobile longitudinal active collision avoidance control method for pedestrians crossing a road based on urban working conditions, and the method is characterized in that the method comprises the steps: S1, obtaining the relative movement speed of a vehicle and the pedestrians to be defined as the pedestrian-vehicle speed, obtaining the relative position of the vehicle and the pedestrians to be defined as the pedestrian-vehicle distance, and obtaining the pedestrian-vehicle distance; s2, a TTC risk assessment model is constructed based on a TTC algorithm, the TTC risk assessment model takes the man-vehicle speed and the man-vehicle distance as input and outputs impact risks, and the impact risks are calculated according to the impact risks. The method comprises the steps of S1, obtaining the collision risk and the vehicle speed, S3, determining the collision avoidance area according to the collision risk and the vehicle speed, S4, establishing active collision avoidance strategies which are in one-to-one correspondence with the collision avoidance areas, and executing the corresponding active collision avoidance strategies according to the collision avoidance areas, and the method has the advantage of being good in driving experience.

    本发明涉及汽车主动安全技术领域,公开了一种基于城市工况行人横穿马路汽车纵向主动避撞控制方法,其技术方案要点是包括S1:获取车辆与行人的相对运动速度以定义为人车速度、获取车辆与行人的相对位置以定义为人车距离,获取车辆的当前行驶速度以定义为车辆速度,获取车辆的加速度以定义为实际减速度,S2:基于TTC算法构建TTC风险评估模型,所述TTC风险评估模型以所述人车速度和人车距离为输入,并输出撞击风险,S3:依据所述撞击风险以及所述车辆速度确定所在的避撞区域,S4:建立主动避撞策略,所述主动避撞策略与所述避撞区域之间一一对应,依据所述避撞区域执行对应的主动避撞策略,其具备驾驶体验好的特点。
