The invention discloses a vehicle radar anomaly detection method and a related device. The method comprises the following steps: acquiring relative data of a vehicle and surrounding objects detected by a vehicle radar; inputting the relative data into a corresponding anomaly detection model to obtain an output abnormality accumulation frequency of the anomaly detection model; and if the output abnormality accumulation frequency meets a preset abnormal condition, determining that the vehicle radar is abnormal. Thus, an anomaly detection model is constructed in advance to determine whether relative data, detected by a vehicle radar, of a vehicle and surrounding objects is abnormal or not, the output abnormality accumulation frequency of the abnormality detection model is recorded, whether the vehicle radar is abnormal is measured through the output abnormality accumulation frequency and the preset abnormal condition, vehicle radar abnormality detection is realized, vehicle radar abnormality can be timely discovered for timely maintenance, and vehicle driving safety is improved; and the vehicle radar anomaly detection method is simple, feasible and easy to implement, and has universality.
Description
technical field [0001] The present application relates to the technical field of detection, and in particular to a method and a related device for abnormal detection of vehicle radar. Background technique [0002] With the rapid development of technology, vehicles are generally equipped with radars, such as millimeter-wave radars, which are called vehicle radars. In the field of vehicle driving, especially in the field of unmanned vehicles, vehicle radar needs to detect relative data between the vehicle and surrounding objects in order to control vehicle driving based on the relative data. [0003] However, the inventor found through research that in the prior art, it is impossible to detect whether the vehicle radar is abnormal through the data detected by the vehicle radar, and it cannot guarantee whether the relative data between the vehicle and the surrounding objects detected by the vehicle radar is correct and valid, thereby affecting the driving experience of the vehi...
