Steering wheel device for fatigue driving detection and safety pre-warning method thereof

Abstract

The invention discloses a steering wheel device for fatigue driving detection and a safety pre-warning method thereof. The device comprises six parts, namely a data acquisition module, a microprocessor control module, a data transmission module, a data storage module, a data analysis module and a safety pre-warning module, wherein the data acquisition module comprises a steering wheel rotation angle acquisition module, a vehicle speed acquisition module, a steering wheel pressure acquisition module and an eye movement characteristic data acquisition module; the acquired data is processed by a microprocessor and then transmitted to the data analysis module; the analysis module performs analytical processing on the acquired data, an adaptive monitoring model is established, real-time differential analysis is performed, the current driving state of a driver is judged, and if a fatigue driving state occurs, forewarning measures are taken. The device disclosed by the invention can realize fatigue driving judgment and rapidly sense the fatigue driving and is high in practicability, sensitivity, and detection result reliability and accuracy, no data needs to be manually input, safety pre-warning can be automatically performed, and the intelligence degree is high.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and in particular relates to a steering wheel device for detecting fatigue based on driver's eye movement characteristics and driving behavior analysis and a safety early warning method thereof. Background technique [0002] With the gradual improvement of the road network, the number of cars is increasing, and the incidence of road traffic accidents, especially vicious traffic accidents, remains high. Fatigue driving is the cause of vicious traffic accidents, which accounts for the highest proportion. It is one of the main causes of road traffic accidents. [0003] Fatigue driving is a serious social problem. It will not only affect its own safety, but also endanger other road users. Therefore, when the driver is driving, how to detect the driver's fatigue and inform the driver at the first time, and take certain emergency measures is the current A key point to solve the problem of fat...

Problems solved by technology

At the same time, this method of simple judgment based on the continuous driving time of the driver cannot take into account the differences in the physical fitness and living habits of different drivers. Affected by other factors, the duration of safe driving is also different

Therefore, using a single driving time as a measure to limit fatigue driving is likely to cause controversy and bring difficulties to the implementation and enforcement of laws and regulations
