Embodiment Construction

[0029] The anomaly detection method of the vehicle millimeter-wave radar in the embodiment of the present invention mainly includes the following steps:

[0030] S1. Simulate the radar detection target, and set the target value of the radar detection target;

[0031] S2. Transmitting a detection signal and an interference signal to perform electromagnetic wave interference on the detection signal;

[0032] S3. The radar detection target performs echo reflection on the detection signal;

[0033] S4. Receive the echo reflection signal, and output the measured value of the radar detection target;

[0034] S5. Determine whether the measured value of the radar detection target is consistent with the target value; if they are consistent, it is determined that the vehicle millimeter-wave radar is normal; if not, it is determined that the vehicle millimeter-wave radar is abnormal.

[0035] Specifically, in the anomaly detection method of the vehicle millimeter-wave radar of the pres...

Abstract

The invention provides an abnormality detection method and system for a vehicle millimeter-wave radar, and the abnormality detection method comprises the following steps: simulating a radar detectiontarget, and setting a target value of the radar detection target; transmitting a detection signal and an interference signal to perform electromagnetic wave interference on the detection signal; performing, by the radar detection target, echo reflection on the detection signal; receiving an echo reflection signal, and outputting an actual measurement value of the radar detection target; judging whether the measurement value of the radar detection target is consistent with the target value or not; if so, determining that the vehicle millimeter-wave radar is not abnormal; and if not, judging that the vehicle millimeter-wave radar is abnormal. According to the abnormality detection method for the vehicle millimeter-wave radar, the target detected by an actual radar can be simulated, whether the vehicle millimeter-wave radar can work normally or not is verified in an electromagnetic wave interference environment, and it is guaranteed that abnormality detection of the vehicle millimeter-wave radar is more comprehensive.

Description

technical field [0001] The invention relates to the technical field of vehicle radar, in particular to an abnormal detection method and an abnormal detection system of a vehicle millimeter wave radar. Background technique [0002] With the development of electronic products, more and more electronic products are used in automobiles, and there is mutual interference between components. The millimeter-wave radar controller on automobiles also has this problem. In addition, in the actual driving environment of the car, the electromagnetic environment is also very complex. In environments such as airports, radar stations, and transmission towers, it is necessary to confirm the radar wave anomaly detection and anomaly processing capabilities of the radar controller. [0003] At present, the abnormality detection of the radar controller cannot simulate the electromagnetic environment in the actual radar detection target, and the judgment logic of the radar detection target cannot ...
