The invention provides an obstacle prompting method and a vehicle-mounted audio system, and the method comprises the steps: determining a target prompt tone corresponding to an obstacle from a prompt tone library based on data collected by a vehicle sensor, and determining the coordinates of the obstacle in a coordinate system of a vehicle; performing coordinate conversion on the obstacle, and converting the coordinate of the obstacle into a coordinate in a spherical coordinate system taking the listening position as an original point; and rendering the target prompt tone by taking the coordinate of the obstacle in the spherical coordinate system as a sound source coordinate. Proper prompt tones are made for the obstacles according to the data of the obstacles collected by the sensors, so that the accuracy of the prompt tones is improved, and the content and interestingness of the prompt tones are enriched; and the spherical coordinates of the obstacle are taken as the sound source coordinates to carry out prompt tone rendering, so that the effect of prompting the direction of the obstacle through the prompt tone is achieved, the obstacle prompting effect is improved, and the driving safety is improved.

    本申请提供一种障碍物提示方法及车载音频系统,该障碍物提示方法包括:基于车辆传感器采集的数据,从提示音库中确定所述障碍物对应的目标提示音,以及确定障碍物在所述车辆的坐标系下的坐标;对所述障碍物进行坐标转换,将所述障碍物的坐标转换为以听音位为原点的球坐标系下的坐标;以所述障碍物在球坐标系下的坐标为声源坐标,渲染所述目标提示音。通过传感器采集的障碍物的数据为障碍物制定适宜的提示音,提高了提示音的准确度,丰富了提示音的内容和趣味性;并以障碍物的球坐标为声源坐标进行提示音渲染,达到了通过提示音提示障碍物方位的效果,提高了障碍物提示的效果,从而提高了行车的安全性。
