The invention discloses a 5G technology-based vehicle driver fatigue monitoring and remote intervention system and method. The driving condition data of an electric automobile is collected through a monocular camera and a steering wheel angle sensor; the lane departure standard deviation and the steering wheel rotation rate are calculated through a microcomputer controller; furthermore, when the lane departure standard deviation is larger than or equal to a lane departure standard deviation threshold value or the steering wheel rotation rate is larger than or equal to a steering wheel rotation rate threshold value, a driving fatigue alarm is sent to a driver; when the microcomputer controller of the automobile counts down for a preset time, a lane departure standard deviation and a steering wheel rotation rate within the preset time after the countdown is finished are calculated; when the lane departure standard deviation or the steering wheel rotation rate is larger than or equal to a corresponding threshold value, fatigue alarm information is uploaded to a cloud server through the 5G CPE; furthermore, the automobile control is adjusted in a drive-by-wire state; and takeover information is issued to a simulation cockpit for takeover. According to the invention, the driving safety is improved; and traffic accidents caused by fatigue can be greatly reduced.
