The invention discloses a deceleration strip identification method and system, and the method comprises the steps: obtaining vehicle information in real time, enabling the vehicle information to at least comprise a vehicle body vertical acceleration signal, carrying out the filtering processing of the vehicle body vertical acceleration signal through a pre-designed filter group, obtaining a filtering result of an effective deceleration strip candidate identifier, and carrying out the recognition of a deceleration strip. And if the filtering result of the effective deceleration strip candidate identifier meets the deceleration strip identification condition, screening the filtering result of the effective deceleration strip candidate identifier to obtain a target deceleration strip identifier, and determining the target deceleration strip identifier as a deceleration strip area so as to ensure the accuracy of obtaining the deceleration strip area to improve the vehicle auxiliary control. The deceleration strip identification mechanism is used for preventing the situation that the same deceleration strip is repeatedly identified when left and right wheels of a vehicle cross the deceleration strip at different times.
本申请公开了一种减速带辨识方法及系统,实时获取车辆信息,车辆信息至少包括车身垂向加速度信号,通过预先设计的滤波器组,对车身垂向加速度信号进行滤波处理,得到有效减速带候选标识的滤波结果,若有效减速带候选标识的滤波结果满足减速带辨识条件,从有效减速带候选标识的滤波结果中筛选得到目标减速带标识,并将目标减速带标识确定为减速带区域,以保证获取减速带区域的准确性来提高车辆辅助控制,减速带辨识机制用于防止因车辆左右轮非同时越过减速带时导致同一减速带进行重复识别的情况发生。
