Vehicle active braking system based on multi-sensor fusion

Abstract

The invention belongs to the technical field of road traffic vehicle control, and particularly relates to a vehicle active braking system based on multi-sensor fusion. The system comprises a multi-sensor obstacle detection mechanism, electronic brake calipers, a camera front-end processing controller, a main control controller and a central gateway. The camera front-end processing controller, themain control controller and a central gateway form the brake controller; the multi-sensor obstacle detection mechanism is composed of a camera, a distance measuring radar and other sensors and is usedfor detecting vehicle obstacles; the camera pre-processing controller is used for carrying out image recognition pre-processing on the data of the camera; the main control controller is a core operation control unit and is used for carrying out fusion processing on external input signals and outputting related information; the central gateway is used for performing multi-network information exchange between the BCU and the whole vehicle and performing signal interaction with communication modules such as a 5G communication module and the like; and the electronic brake calipers are used for braking a vehicle. The system can be installed on any vehicle, the braking distance can be mastered more accurately, and the safety is greatly improved.

Description

Technical field [0001] The present invention belongs to the technical field of road traffic vehicle control, and in particular to a vehicle active braking system based on multi-sensor fusion. Background technique [0002] At present, the car is rapidly popular. According to the traffic claims accident data, the traffic accident of the car is also increased year by year. It is assumed that the vehicle encounters an obstacle, for example, there is a red light in front of the front, the front vehicle speed is low There is an emergence of sudden objects in front, if the driving personnel occurs when the driving personnel occurs due to negligence or answering calls, granient, etc., and the vehicle rear-end accident is very prone to occur. Inventive content [0003] It is an object of the present invention to provide a multi-sensor-based vehicle active brake system capable of effectively reducing vehicle rear-end accidents. [0004] The present invention provides a multi-sensor fusion...

AI Technical Summary

Problems solved by technology

[0002] At present, automobiles are rapidly popularized. According to the data of traffic claims and accidents, it can be analyzed that the traffic accidents of automobiles are also increasing year by year. Suppose the vehicle is driving and encounters an obstacle ahead, for example, there are vehicles waiting for a red light ahead, and the speed of the vehicle ahead is low. , There is an unexpected object in front, etc., if the driver is negligent, answering the phone, distracted, etc., it is very easy to cause a rear-end collision accident
