Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] In the ACC system, the advantages and disadvantages of the camera and the millimeter-wave radar are very obvious, but they complement each other. For the camera, although it can obtain rich scene information and achieve multi-target resolution, it is too sensitive to noise and environmental changes; for millimeter-wave radar, although it can achieve accurate distance and speed detection and adapt to various environmental changes, But its object classification abil...

Abstract

The invention relates to the technical field of automobile self-adaptive cruise systems, in particular to a self-adaptive cruise system and a method thereof. The self-adaptive cruise system involves an environment information acquisition device, an ACC system, a camera and a millimeter wave radar; the environment information acquisition device is used for acquiring visibility data of current environment where a vehicle is located; and the ACC system starts the camera or the millimeter wave radar as a main detector according to the visibility data. The invention aims to provide the self-adaptive cruise system and the method thereof, according to the technical scheme, the technical problem that target processing of an existing ACC system is not accurate enough and has time delay is solved.

Description

technical field [0001] The invention relates to the technical field of automobile adaptive cruise systems, in particular to an adaptive cruise system and a method thereof. Background technique [0002] With the development of autonomous driving technology, more and more models are equipped with an adaptive cruise system based on camera and millimeter-wave radar, that is, Adaptive Cruise Control, or ACC system for short. Through the cooperation of camera and millimeter-wave radar, its Perception can surpass human beings, so that functions such as ACC, ACC STOP ANDGO (ACC S&G), and Forward Collision Warning (FCW) in the ACC system can be realized. [0003] In the ACC system, the advantages and disadvantages of the camera and the millimeter-wave radar are very obvious, but they complement each other. For the camera, although it can obtain rich scene information and achieve multi-target resolution, it is too sensitive to noise and environmental changes; for millimeter-wave rada...
