The invention provides a vehicle parking collision monitoring method, system and device and a controller. The monitoring method comprises the steps that a vehicle vibration signal and an audio signal of a vehicle site are collected; when the vibration signal exceeds a preset vibration threshold value, performing feature extraction on the audio signal to obtain feature data; inputting the feature data into a trained scene classification model for scene recognition; and when the scene is the abnormal scene, controlling the vehicle to send an alarm signal and/or record audio and video. After the vibration monitoring module is triggered, the audio signal monitored by the audio monitoring module is processed and analyzed to judge whether the current scene is an abnormal scene, then alarm and/or audio and video recording are controlled according to the judgment result, and the sensitivity is improved by lowering the threshold value of the vibration monitoring module, so that the missing report rate is reduced, and the user experience is improved. And after the vibration monitoring module is triggered, the audio signal is analyzed and processed again, so that false alarm is avoided, and a specific scene is accurately identified.

    本发明提出一种车辆泊车碰撞监控方法、系统、装置及控制器,监控方法包括:采集车辆振动信号和车辆现场的音频信号;当振动信号超过预设振动阈值时,对音频信号进行特征提取以获取特征数据;将特征数据输入至训练好的场景分类模型中进行场景识别;当场景为异常场景时,控制车辆发出告警信号和/或录制音频、视频。本发明通过振动监测模块被触发后通过对音频监测模块监测到的音频信号进行处理分析,以判定当前场景是否为异常场景,再依据判定结果控制报警和/或录制音频、视频,其通过调低振动监测模块的阈值,以提高其灵敏度,从而降低漏报率,并且在振动监测模块被触发后再次对音频信号进行分析处理,以避免产生误报并准确识别具体场景。
