Abstract

The present application relates to a driver state monitoring method, device, system and controller. The method includes: when the vehicle is in a driving state, acquiring the driver's video information, physiological information and driving information; according to the video information, obtaining the driver's behavioral risk level; according to the physiological information, obtaining the driver's physiological risk level ;According to the driving information, the driver's driving risk level is obtained; the highest risk level among the behavioral risk level, physiological risk level and driving risk level is selected as the driver's current risk level; according to the current risk level, the execution and current risk level corresponding operation. By adopting the method, the state of the driver can be monitored comprehensively and accurately.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a driver state monitoring method, device, system and controller. Background technique [0002] With the improvement of living standards, the number of car ownership has increased year by year, and it has become one of the means of transportation for people's daily travel. However, in recent years, frequent motor vehicle accidents have occurred due to drivers' physical fatigue, illness, tension or inattention, which have brought huge losses to people's lives and properties. Although at present some cars can monitor whether the driver is in a state of fatigue and inattention through the camera installed in front of the driver, so as to send a reminder when the driver is in poor condition. However, the camera can only judge the driver's status through the acquired surveillance video, and cannot detect the driver's disease or other dangerous situations, and there is a ...
