Problems solved by technology

Due to the influence of ambient light, there is a large interference to the captured signal, and the image recognition method has the disadvantage that the detection accuracy is easily affected by ambient light.
[0004] In recent years, there has also been a method of judging fatigue driving based on heart rate parameters, that is, by collecting the current heart rate parameters and comparing them with the preset normal heart rate parameters, and judging whether the driver is awake or fatigued according to the comparison results; However, the accuracy of this method of judging fatigue driving by simply comparing heart rate parameters is not high.

Abstract

A monitoring system for safe driving comprises a signal collection module, a signal processing module, a data processing module and a data analyzing module, wherein the signal processing module extracts heartbeat intervening sequence data and breath intervening sequence data, and corresponding cardiopulmonary reference datum such as heart rate, heart rate variability, heart rate declarative force, breath rate and breath rate variability can be calculated based on the two data via the data processing module; a series of feature values of an original waveform can be acquired and data processing amount can be reduced, so analyzing difficulty can be reduced; heart rate parameters and breath parameters are comprehensively considered via the data analyzing module, so driver fatigue degree and risk of spasmodic diseases can be respectively predicted; safe driving rises can be accurately monitored in real time, so drinking safety can be ensured; relatively, the invention further provides a safe driving monitoring method, an automobile including safe driving monitoring system and a storage medium.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a method and system for monitoring safe driving, a vehicle, and a readable storage medium. Background technique [0002] The driver needs to concentrate during the driving process. The driver is highly stressed for a long time, the brain is prone to fatigue, and the probability of sudden diseases (such as myocardial infarction and acute heart failure, etc.) is also relatively high. Therefore, it is necessary to protect the driver Driving safely is of the utmost importance. [0003] In order to ensure the driver's safe driving, the existing technology often reflects the risk of safe driving by predicting the driver's fatigue level. Traditional fatigue driving detection often uses image recognition methods to record the driver's facial expressions through the camera, or analyze facial expressions such as blinking. Features, eye signals, head movement, etc. infer the driver'...
