Driver driving enthusiasm identification device and method based on intelligent steering wheel

Abstract

The invention discloses a driver driving enthusiasm identification device and method based on an intelligent steering wheel. The identification device comprises a steering wheel, a signal conditioning module and a processing unit, the steering wheel and the processing unit are connected with the signal conditioning module, a plurality of pressure sensors are correspondingly arranged at the left hand and right hand grasping parts of a driver on the steering wheel, and the plurality of pressure sensors arranged at the left hand and right hand grasping parts of the driver on the steering wheel are all connected with the signal conditioning module. The identification method comprises the following steps: step 1, building a driver driving enthusiasm identification device; step 2, acquiring grip data under different driving enthusiasm; step 3, calculating a grip distribution map; step 4, constructing an identification model; and step 5, training the identification model. The method and the device have the advantages that: operation and control of a driver on the steering wheel can be reflected more meticulously, driving enthusiasm is recognized accurately in real time, the driver does not need to wear various myoelectricity or electroencephalogram devices, and practicability is improved.

Description

Technical field [0001] The present invention relates to a driving positive recognition apparatus and method, and more particularly to a driver driving enthusiasm recognition apparatus and method based on a smart steering wheel. Background technique [0002] At present, with the deep integration of modern manufacturing and new generation information technology, automatic driving has become the trend and frontier of the development of automotive industrial. However, fully automatic driving is still limited by the objective laws and potential moral legal issues of technology development, and cannot be achieved in the foreseeable future. It is difficult to rapidly improve the automatic driving level in this stage to completely automatic driving level, and the concept of human machine is widely concerned and studies. The human machine is a technical architecture that the human driver and automation system cooperates to complete the driving task. The driving safety is enhanced through ...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the existing research uses the camera and artificial intelligence technology to identify the driver's fatigue state. Some studies judge whether the driver has let go of the hand based on the grip of the steering wheel. There are few studies on the identification of the driver's driving enthusiasm through the intelligent steering wheel.
