Abstract

An automobile forward safety system based on information fusion belongs to the field of automobile accessories and aims at judging corresponding position of an automobile in the external environment through a foresight digital camera and radar data. The automobile forward safety system comprises an environment sensor, a controller and an actuator, wherein the environment sensor detects the external environment of the automobile in real time and transmits information to the controller through an automobile network, the controller comprehensively judges information of the environment sensor and information of an automobile gesture sensor, gives out instructions to different levels of the actuator through the automobile network, and the actuator is divided into an a-prompting level, a b-alarm level and a c-intervene level according to function level. The automobile forward safety system judges the corresponding position of the automobile in the external environment through the forehead digital camera and radar data and effectively performs functional complementation. The automobile forward safety system is mainly used in forward safety forecasting and protection of automobiles.

Description

technical field [0001] The invention belongs to the field of auto parts. Background technique [0002] Automotive forward safety technology has been developing vigorously, and radar or camera has been used in the recognition of the environment in front of the vehicle. However, the radar cannot identify the road conditions, and the natural defects of the camera are greatly affected by the external environment, which greatly limits the development of technology. Contents of the invention [0003] The purpose of the present invention is to judge the relative position of the car in the external environment based on the information fusion forward safety system of the car through the front-view camera and radar data. [0004] In the present invention [0005] a. The environment sensor should at least include the following two items: [0006] ①Vehicle radar: usually 77GHz or 24GHz, with a detection range of 30-200 meters; [0007] ②Forward-looking camera: the dynamic range of...
