The invention provides an automatic emergency braking control method which comprises the steps that the increasing duration and the parking distance corresponding to each braking grade are determined according to the driving style, each braking grade corresponds to one target deceleration, the increasing duration represents the duration when the braking deceleration is increased from zero to the target deceleration in a preset increasing mode, and the parking distance corresponding to each braking grade is determined according to the parking distance. The parking distance represents the distance between the own vehicle and the front vehicle when the own vehicle stops moving at the target deceleration in a uniform deceleration manner; for each braking grade, a first safety distance is calculated at least according to the increasing duration and the parking distance; determining a triggering range of each braking grade at least according to the first safety distance of each braking grade; and if the distance between the vehicle and the front vehicle at the current moment is within the triggering range of a certain braking grade, braking is requested at the current moment according to the increasing duration and the target deceleration corresponding to the braking grade. According to the method and the device, the difference of the driving styles can be fed back more accurately, so that the experience of a driver during AEB system intervention is improved.

    本申请提供一种自动紧急制动控制方法,该方法包括:根据驾驶风格确定增长时长和每个制动等级对应的停车距离,其中,每个制动等级对应一个目标减速度,增长时长表示制动减速度以预设增长方式从零增长到目标减速度的时长,停车距离表示自车停止以目标减速度匀减速运动时自车与前车的间距;针对每个制动等级,至少根据增长时长和停车距离计算得到第一安全间距;至少根据每个制动等级的第一安全间距确定每个制动等级的触发范围;若当前时刻自车与前车的间距处于某一制动等级的触发范围,则在当前时刻根据增长时长和该制动等级对应的目标减速度请求制动。通过本申请,能够更准确地反馈驾驶风格的差异性,从而提高驾驶员在AEB系统干预时的体验。
