The invention relates to audio-based road condition sensing and detection techniques for autonomous driving vehicles. A sound signal is received by one or more microphones disposed at the ADV. The sound signal is analyzed to extract features of the road on which the ADV is driving. And determining the road condition of the road based on the extracted features. Path planning and velocity planning are performed to generate a trajectory based on the road condition. And controlling the ADV to autonomously drive according to the generated trajectory.

    本公开涉及用于自主驾驶车辆的基于音频的道路状况感测和检测技术。通过设置在ADV的一个或多个麦克风接收声音信号。分析声音信号以提取ADV正在其上驾驶的道路的特征。基于提取的特征确定道路的道路状况。执行路径规划和速度规划以基于道路状况生成轨迹。根据生成的轨迹控制ADV以自主驾驶。
