Problems solved by technology

However, in the process of driving, it is difficult for the driver to perceive that he is already in a state of fatigue driving, which leads to the risk of dangerous driving. Therefore, it is necessary to propose an early warning method for dangerous driving for fatigue driving behavior.

Embodiment Construction

[0052] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0053]In related technologies, danger warning methods for fatigue driving include the following:

[0054] (1) Based on the real-time trajectory of the vehicle, by detecting the driving state of the vehicle, it is indirectly judged whether the current driver is fatigued or not;

[0055] (2) Collect the driver's facial image, and analyze and process the image, for example, judge the driver's fatigue degree by image information such a...

Abstract

The invention discloses a dangerous driving early warning method, device and equipment and a related system. The method can comprise the steps that the vehicle speed, the heart rate value of a driver and the grabbing force value of the driver for grabbing a steering wheel are obtained; the risk level of dangerous driving is determined according to the vehicle speed, the heart rate value and the gripping force value; and generating early warning information corresponding to the risk level. Through comprehensive analysis and judgment of multiple dimensions such as the vehicle speed, the heart rate value and the gripping force value, whether the driver is in the fatigue driving state or not is analyzed more accurately, the risk level of fatigue driving of the driver is evaluated to warn the driver, the driving safety requirement is met, and traffic accidents are reduced.

Description

technical field [0001] The present invention relates to the technical field of dangerous driving early warning, in particular to a dangerous driving early warning method, device, equipment and related system. Background technique [0002] Cars play an increasingly important role in people's production and life, and the number of cars is increasing year by year. Then, there are some safety hazards in driving cars, among which dangerous driving is the main cause of traffic accidents. one. [0003] Fatigue driving is a relatively common dangerous driving behavior. It refers to the phenomenon that the driver's physiological and psychological functions are out of balance after driving continuously for a long time, and the driving skill declines objectively. Fatigue driving can affect various aspects such as driver's attention, feeling, consciousness, thinking, judgment, will, decision and motion. Driver fatigue driving can easily lead to road traffic accidents. However, in the...
