Intelligent recognition steering wheel based on multi-sensor fatigue driving and recognition method thereof

Abstract

The invention discloses an intelligent recognition steering wheel based on multi-sensor fatigue driving and a recognition method thereof; the steering wheel comprises a steering wheel body and a steering column, and relates to the technical field of automobile parts. According to the intelligent recognition steering wheel based on multi-sensor fatigue driving and the recognition method of the intelligent recognition steering wheel, a pressure sensor, a blood oxygen sensor and a camera monitor a driver at the same time, when the hand pressure value detected by the pressure sensor is smaller than an alarm threshold value, alarm reminding is conducted, and the blood oxygen sensor collects the blood oxygen index of the driver; a central processing unit calculates the fatigue state value of a driver according to the blood oxygen index, the camera collects the face information of the driver, the blinking frequency of the driver is calculated through an image processing unit, fatigue is judged by monitoring the blinking condition of the driver through videos, the state of the driver is judged more accurately through multiple monitoring modes. Therefore, when a driver is in fatigue driving, the driver can be reminded in time, and accidents are prevented.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an intelligent identification steering wheel based on multi-sensor fatigue driving and an identification method thereof. Background technique [0002] The steering wheel is the steering wheel, which is a wheel-shaped device for controlling the driving direction of automobiles, construction machinery, agricultural vehicles, etc. The steering wheel is generally connected to the steering shaft through splines, and its function is to convert the driver's force on the edge of the steering wheel into After the torque is transmitted to the steering shaft, the driver controls the steering wheel to make the car maintain or change the direction of motion according to the driver's intention. Therefore, the steering wheel is also an important security component. The steering wheel is composed of a hub, spokes, rims and pads The hub, rim and spoke of the steering wheel are usually made of ...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides an intelligent recognition of the steering wheel and its recognition method based on multi-sensor fatigue driving, which solves the situation that the detection method is single and judgment errors are prone to occur, resulting in the driver being easily caught by the steering wheel during driving. System interference reduces the driving experience, and the continuously sprayed liquid is more likely to blur the driver's vision in front of the driver who is already in a state of fatigue, which increases the probability of accidents
