AI Technical Summary

Problems solved by technology

However, in actual use, the performance of the front and rear crossing warning function is often unsatisfactory due to the certain angle between the parking space and the road driving direction. Directly using the V2X strategy to solve this problem has high accuracy, but it requires people, vehicles, vehicles, and objects. The cost of networking is relatively high, and it is not suitable for large-scale networking

Abstract

The embodiment of the present invention discloses a method, device, storage medium and vehicle for determining a warning area. The compensation angle is determined according to road information and / or vehicle information, wherein the road information is collected by a camera; according to the radar detection angle and the radar installation angle Determining a pre-warning area; adjusting the pre-warning area according to the compensation angle to determine a target warning area. The technical solution of this embodiment relies on the camera sensor installed in the front / rear of the vehicle to collect road information and interact with vehicle information, accurately calculate the parking angle of the vehicle and the driving direction of the vehicle, and feed back to the radar for self-adjustment of the warning range. Fusion and accurate identification of obstacles to reduce false positives.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automatic driving, and in particular to a method, device, storage medium and vehicle for determining a warning area. Background technique [0002] At present, many vehicles with driving assistance or automatic driving functions are equipped with front / rear corner radars and front / rear cameras, and have front / rear cross-traffic warning / braking functions. [0003] The existing front and rear crossing alarm functions mainly detect obstacles in the blind area of ​​the field of vision through radar. The blind area refers to a rectangular area determined according to the radar detection angle and installation angle, and the alarm and control are set by TTC or distance. move strategy. However, in actual use, the performance of the front and rear crossing warning function is often unsatisfactory due to the certain angle between the parking space and the road driving direction. Directly usin...
