A vehicle radar adjustment control method

Abstract

The present invention provides a vehicle radar adjustment control method, belonging to the technical field of automobiles. The problems of complex structure and small blind area detection range in the prior art are solved. The method comprises the steps of (1) judging whether a current radar array needs to be adjusted or not, if so, completing the correction of a radar array initial angle through a swing mechanism, and if not, entering into a normal working state, (2) after entering into the normal working state, judging the driving state of a vehicle at a next time, selecting a corresponding working mode in a working mode selector according to a judgment result, adjusting the radar array to a needed angle through the swing mechanism, and entering into a radar array swing angle adjustment period, and (3) in the radar array swing angle adjustment period, through an adaptive algorithm, maintaining the angle of the radar array at a needed adjustment angle. According to the method, while the cost of a whole automobile is reduced, the range of the blind area detection is increased.

Description

Technical field [0001] The invention belongs to the technical field of automobiles, and relates to a vehicle radar adjustment control method. Background technique [0002] When the vehicle is driving, the driver observes the road and vehicle conditions on both sides and behind the vehicle through the rearview mirrors on both sides of the front window. Due to the insufficient field of view of the rearview mirror of the vehicle, there is always a blind spot for visual observation on both sides of the window of the driver while driving, and the driver cannot observe whether there are vehicles or pedestrians in the area through the rearview mirror. Therefore, there are potential safety hazards in driving links such as lane changing and merging. [0003] In response to the above-mentioned blind area problem, a large number of vehicles are currently equipped with active safety radars to avoid the blind area problem. The radar arrangement is fixed. Due to the limited detection angle, in ...

AI Technical Summary

Problems solved by technology

This invention needs to realize the safety warning function of the blind area through the master and slave control framework of the system, and the structure is complicated. In addition, the ultrasonic probes arranged on both sides of the vehicle body in this invention are fixed, and the detection range is small, which is not suitable for use under various working conditions. small range
