Problems solved by technology

[0004] The traditional blind spot monitoring radar, the left and right radars work relatively independently, and the vehicle directly behind does not affect the lane change or turn of the vehicle, so it does not meet the alarm requirements. However, when the radar detects the target, the radar wave reflection point changes, resulting in the target detected by the radar. Information such as distance and angle will fluctuate in a small range. Although radar tracking algorithms and some filtering algorithms can effectively filter some small fluctuations, when the rear target vehicle deviates to the left or right, due to the influence of small fluctuations, Although the center point of the rear body does not actually exceed the dangerous boundary of the vehicle, the target detected by the radar has entered the alarm range, so the radar misjudgment is triggered, which causes the driver to misjudge and cause unnecessary losses. The utility model can effectively reduce the And even avoid the false alarm of the radar directly behind caused by this reason

Embodiment 1

[0037] The method comprises the steps of:

[0038] S1, the left radar 2 and the right radar 3 detect the target 2 in the respective monitoring area, that is, the vehicle behind, and the detected signal is transmitted to the first CAN bus by the first CAN bus. The control system obtains information data through the data acquisition module in the control system, and then processes the information data of the target by the data processing module to obtain target information;

[0039] S2, judging whether the target triggers the alarm range of the area directly behind monitored by the left radar 2; when the left radar 2 alarm is not triggered, the left radar 2 does not generate an alarm, and when the target triggers the alarm range of the left radar 2 , the left radar 2 sends a target verification request to the right radar 3, the right radar 3 receives the verification request, and verifies through a target fusion algorithm, and the target fusion algorithm includes the following s...

Embodiment 2

[0056] The method comprises the steps of:

[0057] S1. The left radar 2 and the right radar 3 detect the same target in their respective monitoring areas, and the detected signals are transmitted to the control system through the first CAN bus through the first CAN bus, and then passed through the control system The data acquisition module obtains the information data, and then the data processing module processes the information data of the target to obtain the target information;

[0058] S2, judging whether the target triggers the alarm range of the area directly behind monitored by the right radar 3; when the right radar 3 alarm is not triggered, the right radar 3 does not alarm, and when the target triggers the alarm range of the right radar 3 , the right radar 3 sends a target verification request to the left radar 2, the left radar 2 receives the verification request, and verifies through a target fusion algorithm, and the target fusion algorithm includes the following ...

Abstract

The invention discloses a method for suppressing false alarms of a radar monitoring system, comprising a radar monitoring system, the radar monitoring system includes a left radar and a right radar installed at the rear of the vehicle, and is used to monitor the blind area of ​​the vehicle, the left radar and the right radar They are respectively connected to the control system of the vehicle through the first CAN bus, and the second CAN bus is connected between the left radar and the right radar; the monitoring target triggers the alarm range of one radar, and sends target verification to the other side radar Request, the radar on the other side verifies whether the target is detected, and feeds back to the control system. If the target is detected on the other side, no warning information is output. Otherwise, the radar on the other side cannot detect the target, and the control system outputs Early warning information. The method of the invention can effectively suppress false alarms generated by the radar for monitoring the rear blind area of ​​the vehicle.

Description

technical field [0001] The invention relates to the field of automotive radar, in particular to a method for suppressing false alarms of a radar monitoring system. Background technique [0002] Frequent traffic safety problems have brought great pain and property loss to people, prompting people to continuously increase their attention to motor vehicle safety. Major car companies have also launched their own active and passive safety configurations to meet the current needs of consumers for driving safety. Vehicle Blind Spot Monitoring System: The millimeter-wave radar detects the vehicles in the blind spots on both sides of the vehicle, and reminds the driver to pay attention to the hidden dangers on the side and rear, so as to reduce or even avoid accidents during lane changes and turns. [0003] The vehicle blind spot monitoring system mainly relies on millimeter-wave radar to assist the driver in judging whether the vehicle behind him will affect the vehicle's overtakin...
