Abstract

The invention discloses a driver fatigue determining method and device; the method comprises the following steps: using sensors to detect environment conditions in a cab, and determining a fatigue duration threshold according to the cab environment conditions; detecting the driver driving duration, and determining whether the driver driving duration is bigger than the fatigue duration threshold or not; if yes, determining the driver driving in fatigue. The method and device can combine environment conditions so as to determine the driver fatigue states.

Description

technical field [0001] The present invention relates to the v2x field, in particular to a method and device for judging driver fatigue. Background technique [0002] Fatigue driving is an important factor affecting vehicle driving safety. According to the statistics of the traffic department, most of the traffic accidents have a great relationship with fatigue driving. It is of great significance to detect driver fatigue driving to prevent fatigue driving and prevent traffic accidents. At present, the methods of fatigue driving detection are mainly realized by detecting the blinking frequency of the driver's eyes. The algorithms of these methods are relatively complex, and are greatly affected by the environment and individual differences. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a driver fatigue judgment method and device, which can determine the driver's fatigue state in combination w...
