The invention discloses an autonomous directional vehicle whistling warning method, system and device, relates to the technical field of vehicle noise control, and is used for solving the problems that in the prior art, a vehicle horn does not consider environmental factors, whistling generates environmental noise, and directional and fixed-intensity sounding cannot be achieved. Comprising the following steps: acquiring environment information such as environment sound source information and surrounding driving condition information within a preset distance range around a vehicle carrying equipment; based on the environment information, determining position information of a target emitting an abnormal sound source and/or an abnormal target having an abnormal driving behavior within a preset distance range around the vehicle carrying the equipment; according to the relative speed and the distance between the vehicle carrying the equipment and the abnormal target, early warning sound wave information sent by the vehicle carrying the equipment for the abnormal target is obtained through calculation; and the vehicle carrying the equipment emits vector form early warning sound waves with specific sound wave intensity for the abnormal target according to the sound production direction, so that directional and fixed-intensity whistling is realized.
本发明公开一种自主式定向车辆鸣笛警示方法、系统及装置,本发明涉及车辆噪声控制技术领域,用于解决现有技术中车辆喇叭没有考虑环境因素,鸣笛产生环境噪声,无法实现定向、定强度发声的问题。包括:获取搭载设备车辆的车周预设距离范围内的环境声源信息以及周围行驶状况信息等这些环境信息;基于环境信息确定搭载设备车辆的车周预设距离范围内的发出异常声源的目标和/或具有异常驾驶行为的异常目标的位置信息;根据搭载设备车辆与异常目标之间的相对速度以及相距的距离,计算得到搭载设备车辆针对异常目标发出预警音波信息;搭载设备车辆按照发声方向针对异常目标发出特定音波强度的矢量形式预警音波,实现定向、定强度鸣笛。
