Embodiment Construction

[0055] The technical solution of the present invention is clearly and completely described below, obviously, the described embodiments are only some embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0056] The invention discloses a driving state detection method, which includes driving posture detection and facial expression detection.

[0057] The driving posture detection specifically includes: using the sensor on the steering wheel to detect the driver's driving posture, and sending it to the central processing unit, and the central processing unit judges whether the driver's driving posture is correct.

[0058] If there is an emergency during the driving of the car, it is difficult to conveniently control the steering wheel with one hand to adjust the directi...

Abstract

The invention discloses a driving state detection method. The driving state detection method comprises the steps of driving posture detection and facial expression detection, wherein driving posture detection specifically comprises the steps that a sensor located on a steering wheel is utilized to detect the driving posture of a driver and send the driving posture of the driver to a central processing unit, and the central processing unit judges whether the driving posture of the driver is correct or not; and facial expression detection comprises the steps that an image collector located on acab is utilized to collect facial information of the driver and send the facial information of the driver to the central processing unit, then the central processing unit conducts feature extracting on the collected facial information, and a trained face recognition model is utilized to recognize the facial information so as to judge whether the mental state of the driver is normal or not. The driving state detection method mainly aims at correcting the driving posture of novice drivers, cultivating good driving habits and correcting bad habits of skilled drivers, and has the characteristics of high reliability and high efficiency.

Description

technical field [0001] The invention relates to the field of automobile safe driving, in particular to a driving state detection method. Background technique [0002] Along with improving constantly of people's living standard, automobile has become a kind of necessary living vehicle in people's daily life. The number of cars in my country is growing rapidly. Correspondingly, there are more and more novice drivers, and the incidence of traffic accidents continues to increase. Among them, the ratio of wrong driving posture and bad driving habits also continues to increase. According to statistics, the incorrect driving posture of the driver and the lack of vision of the mirror caused by it have become an important factor leading to traffic accidents. Good driving posture and driving habits are the guarantee of people's life and property safety. [0003] At present, when the driving posture is detected, the driving fatigue detection is mainly carried out. There are four detec...
