Embodiment Construction

[0077] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0078] At present, vehicle intelligent driving technology has been developed by leaps and bounds. Taking vehicle AEB and ACC systems as examples, both of them have been widely used in vehicles. Usually, the target recognition method of the two in the application is to select the equal-width area directly in front of the vehicle as the target recog...

Abstract

The embodiment of the invention provides a target identification method and device. When a vehicle steers, the driving curvature radius of the vehicle is determined according to the distance between afront wheel and a rear wheel of the vehicle is the distance between the front wheel and the rear wheel of the vehicle. The driving curvature radius of the vehicle and the driving speed of the vehicleare calculated and a target identification range is determined. Furthermore, a target is identified according to the target identification range, such as environment and vehicle information. The target selection mode is changed to efficiently select the most proper target. The invention is suitable for ACC, AEB systems loaded on all vehicles. The problem that the system mistakenly identifies the target or misses identification to send out error control under the curve condition is solved during curves, the system performance is greatly optimized under the condition that the cost is not increased, and the invention is suitable for wide application.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicles, and in particular, to a target recognition method and device. Background technique [0002] With the development of social economy and the continuous improvement of people's living standards, vehicles are becoming more and more popular and have more and more functions. They have become an important means of transportation for people to travel. [0003] At present, vehicle intelligent driving technology has been developed by leaps and bounds. Taking vehicle AEB and ACC systems as examples, both of them have been widely used in vehicles. Usually, the target recognition method of the two in the application is to select the equal-width area directly in front of the vehicle as the target recognition area according to the calibration of the vehicle width. Or use the method of adding a camera to fuse with the radar and combine the lane lines to judge the target. Among them, AEB ...
