Bus driver hand-off-steering-wheel detection warning system and warning method

Abstract

The invention discloses a bus driver hand-off-steering-wheel detection warning system and a warning method. The system comprises a camera, a digital signal processor, a GPS (global position system) module, a control module and a GPRS (general packet radio service) module. The method includes the steps of 1), colleting images of a driver operating steering wheel; 2), calculating the images by adopting an operator detection recognition method, distinguishing the state of a driver hand-off steering wheel, and judging out whether a driver is in the state of left-operating hand-off steering wheel, the state of right-operating hand-off steering wheel or the state of both-hand-off steering wheel; 3), judging whether to trigger warning signals or not by adopting a warning logical judgment method; 4), outputting information to an upper computer. By the detection warning system and the warning method, easiness in setting is achieved, the visual system is downsized, a universal foundation technology platform for image processing is provided, any compulsory interference on the body of the driver is omitted, cost is low and the like.

Description

technical field [0001] The invention relates to a passenger car driver's hands-off steering wheel detection and early warning system and early warning method, belonging to the technical field of automobile safety driving supervision. Background technique [0002] With the continuous development of social economy, the number of motor vehicles has increased rapidly year by year, and traffic accidents have remained high. Studies have shown that the number of traffic accidents caused by drivers' human factors accounts for more than 90% of the total, and 87% of them are caused by motor vehicle drivers' illegal operations, lack of experience, and poor behavioral norms. The driver's illegal driving behavior is closely related to his incorrect driving operation, especially the driving behavior of the driver leaving the steering wheel, which is easily ignored by the driver, causing the driver to ignore the traffic on the road due to lack of attention Dangerous, likely to cause serio...

AI Technical Summary

Problems solved by technology

[0004] At present, some operating vehicles such as buses and medium-sized buses in my country are equipped with monitoring cameras, but due to the lack of corresponding technical means, it is impossible to realize the early warning of dangerous driving behavior, and it cannot really serve the purpose of supervising the driver's safe driving.
