Embodiment Construction
[0057] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0058] Such as figure 1 As shown, the present disclosure provides a method of determining drowsy driving, the method comprising:
[0059] In step 101, obtain the driver's cerebral blood oxygen scale index, facial fatigue expression and pupil closure;
[0060] In step 102, the first fatigue condition probability is determined according to the cerebral blood oxygen scale index, the second fatigue condition probability is determined according to the facial fatigue expression, and the third fatigue condition probability is determined according to the pupil closure degree;
[0061] In step 103, according to the prior probability of fatigue driving, the first fat...

The invention relates to a method and a device for determining the fatigue driving and a vehicle. The method comprises the steps of acquiring the brain blood oxygen scale index, the facial fatigue expression and the pupil closing degree of a driver; determining a first fatigue condition probability according to the brain blood oxygen scale index; determining a second fatigue condition probabilityaccording to the facial fatigue expression; determining a third fatigue condition probability according to the pupil closing degree; according to the fatigue driving prior probability, the first fatigue condition probability, the second fatigue condition probability and the third fatigue condition probability, determining the fatigue driving posterior probability. The fatigue prior probability isthe fatigue probability of a previous test on the driving fatigue condition of the driver. According to the invention, three indexes are adopted at the same time to determine the fatigue driving probability of the driver. Therefore, the evaluation is more comprehensive and more accurate.
Description
technical field [0001] The present disclosure relates to the traffic field, in particular to a method, device and vehicle for determining fatigue driving. Background technique [0002] Vehicle driving is a potentially dangerous behavior. There are many factors that cause traffic accidents. For example, common factors include the following: [0003] 1. With the popularity of vehicles, the road conditions are more complicated; [0004] 2. The performance of the vehicle is improved and the speed is faster; [0005] 3. The faster pace of urban life causes driver fatigue; [0006] 4. Aging trend, the average age of drivers is rising, and the response is declining; [0007] 5. The competition in the transportation industry is fierce, and a large number of employees are in a state of fatigue driving. [0008] Among them, fatigue driving has become the number one road killer. When the driver is driving, when there is a situation on the road, he needs to make timely operations w...
