Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] When driving a vehicle at a high speed, the driver's attention is very concentrated and he is always in a state of high mental stress. With the continuous increase of speed and the extension of driving time, the driver will gradually experience fatigue. Driving on the highway, the road environment is single, the traffic interference is small, the speed is stable, and the noise and vibration frequency in the driving are small, which...

Abstract

The invention provides a driving safety monitoring method. The method includes the steps of using a speed sensor connected to the output end of an engine to monitor vehicle speed and output a vehicle speed signal; using a first analog-digital converter to convert the vehicle speed signal from an analog signal into a digital signal; using a steering wheel sensor connected to a steering wheel to detect wheel turn and output a steering wheel turn signal; using a second analog-digital converter to convert the steering wheel turn signal from an analog signal into a digital signal; using a controller to receive the digital vehicle speed signal and the digital steering wheel turn signal, using a program implemented virtual timer to time when a variation change of the vehicle speed signal and that of the steering wheel turn signal are both less than a reference value, and outputting a control signal when the time is up; using a vibrator disposed below a driver's seat to receive the control signal, and allowing the vibrator to vibrate according to the control signal.

Description

Technical field [0001] The invention relates to the field of vehicle electronics, in particular to a safe driving monitoring method. Background technique [0002] The development of automobiles not only has a huge effect on the social economy, but also has an important impact on human life. Cars have become the main means of transportation for people to travel, and their convenience is unmatched by planes, ships and trains. [0003] As an emerging economy, China has become the world's largest consumer of automobiles. At present, the number of motor vehicles in my country has exceeded 100 million. [0004] Driving fatigue refers to the imbalance of physiological function and psychological function of the driver after a long time of continuous driving, and the phenomenon of objectively decreasing driving skills. Drivers have poor or insufficient sleep quality and are prone to fatigue when driving vehicles for a long time. Driving fatigue will affect the driver's attention, feeling, ...
