Lane departure warning method and device based on vibration of steering wheel

Abstract

The invention discloses a lane departure warning method and device based on vibration of a steering wheel. According to the scheme, a video sensor receives current driving behavior data of a communication gateway through a wireless fidelity (Wi-Fi), and the current driving behavior data and headstock video data acquired by the video sensor are combined to judge whether it is initiative vehicle steering by a driver or lane departure; if it is judged to be lane departure, the video sensor transmits a warning signal to the communication gateway which then transmits the warning signal to a wireless driving module to drive the steering wheel to vibrate, and the function of warning is achieved; and the warning device comprises the video sensor used for judging lane departure, the vibrating steering wheel, the communication gateway and the wireless driving module. The lane departure warning method and device based on vibration of the steering wheel have the advantages that by full use of Wi-Fi networking characteristics and through combined analysis on the driving behavior data and the acquired headstock video data, the high false alarm rate caused by the method that currently, lane departure is only judged through the video sensor for most vehicles is avoided, and the driving reminding of the vibrating steering wheel is more direct and efficient.

Description

technical field [0001] The invention relates to the field of automobile driving safety, in particular to a lane departure warning method and device based on steering wheel vibration. Background technique [0002] Wi-Fi technology is a technology that can wirelessly connect terminals such as personal computers and handheld devices (such as pads and mobile phones) to each other. It is the most widely used wireless network transmission technology today. [0003] The current lane departure methods are basically based on the analysis and judgment of the vehicle's video sensor, which has a high false alarm rate and affects the actual use effect. Voice prompts are unreliable in certain environments. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a wireless Wi-Fi network, high reliability, good driving safety effect, intuitive and effective reminder, and widely applicable lane departure alarm method and device based on...
