The embodiment of the invention provides a radar fault detection method and device, a vehicle and a storage medium, and relates to the technical field of vehicle-mounted radars. According to the radar fault detection method and device, the vehicle and the storage medium provided by the embodiment of the invention, the shielding state of the radar is determined according to the signal-to-noise ratio of the radar echo, the trace point number currently acquired by the radar and the object number, and whether the radar breaks down or not is determined according to the shielding state of the radar. The shielding state of the radar is comprehensively judged by combining multiple factors (the signal-to-noise ratio of radar echoes, the number of objects obtained by the radar and the number of trace points) instead of a single factor (the number of objects), the accuracy of judging the shielding state of the radar is improved, the situations of misjudgment and missed judgment can be reduced, and therefore misinformation and missed information of radar faults can be reduced, and the detection accuracy of the shielding state of the radar is improved. And the vehicle driving safety is improved.
本申请实施例提供一种雷达故障检测方法、装置、车辆及存储介质,涉及车载雷达技术领域。在本申请实施例提供的雷达故障检测方法、装置、车辆及存储介质中,根据雷达回波的信噪比、雷达当前获取到的点迹数量以及物体数量,确定雷达的遮挡状态,根据雷达的遮挡状态,确定雷达是否出现故障。通过结合多因子(雷达回波的信噪比、雷达获取到的物体数量以及点迹数量)而非单一因子(物体数量)来综合判定雷达的遮挡状态,提高了判断雷达遮挡状态的准确率,可以减少误判以及漏判的情况,从而可以减少对雷达故障的误报以及漏报,提升车辆行驶的安全性。
