Embodiment 1

[0027] figure 1 It is a schematic flowchart of a method for judging fatigue driving based on driving behavior provided by Embodiment 1 of the present invention. The behavior is determined by a device for judging fatigue, which can be implemented in the form of software and / or hardware.

[0028] Such as figure 1 Described, the method of the present embodiment comprises:

[0029] S110. Acquire historical driving data information and first environment information of the target user.

[0030] Among them, the target user can be understood as a driver driving a vehicle. The historical driving data can be the driving data within a preset period, and the user's driving data in half a year, one year, and one and a half years are optional. The driving data may include information about the environment in which the user drives the vehicle, the driving distance, the driving speed, the driving duration, and the rest time during driving the vehicle. The environmental information of the...

Embodiment 2

[0043] The above technical solution determines the fatigue driving duration corresponding to the target user, that is, the reference driving duration, according to the historical driving data of the target user and the first environmental information, that is, the current environmental information. In order to improve the fatigue driving duration corresponding to the target user, it is also necessary to update or correct the fatigue driving duration according to the actual environmental information of the vehicle during driving. figure 2 It is a schematic flowchart of a fatigue driving early warning method provided by Embodiment 2 of the present invention.

[0044] Such as figure 2 Described, the method of the embodiment of the present invention comprises:

[0045] S210. Collect the current facial information of the target user based on the facial image collection module, and compare the facial information of the target user with the facial information stored in the databas...

Embodiment 3

[0075] image 3 It is a schematic structural diagram of a device for determining fatigue driving based on driving behavior provided by Embodiment 3 of the present invention. The device includes: a data acquisition module 310 , a fatigue driving duration determination module 320 and a fatigue driving determination module 330 .

[0076] The acquisition data module 310 is used to acquire the historical driving data information and the first environmental information of the target user; wherein, the historical driving information includes historical environmental information, and the environmental information includes ambient temperature, ambient light and weather; determining fatigue driving The duration module 320 is configured to determine the fatigue driving duration of the target user according to the historical driving data information and the first environmental information, and use the fatigue driving duration as a reference driving duration; the fatigue driving module 330 ...

Abstract

The embodiment of the invention discloses a method and device for determining fatigue driving based on driving behaviors, wherein the method comprises: acquiring the historical driving data information of a target user and first environment information, wherein the historical driving data information includes historical environment information, and the environment information includes ambient temperature, ambient light, and weather; determining, according to the historical driving data information and the first environment information, the fatigue driving duration of the target user, and usingthe fatigue driving duration as a reference driving duration; and determining whether the target user is in a fatigue driving state according to the reference driving duration. The method and devicecan determine the fatigue driving duration corresponding to the target user in advance according to the historical driving data information of the target user and the environment information so as totimely remind the user, thereby improving the vehicle-driving safety and reliability of the user.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of safe driving, and in particular to a method, device, device and storage medium for judging fatigue driving based on driving behavior. Background technique [0002] When the driver continuously drives the vehicle for more than a certain period of time, it is called fatigue driving. Fatigue driving is prone to physiological and psychological disorders, which can be understood as changes in physiological parameters, and objectively manifested as a decline in driving skills, which can be understood as slow and slow operation of the vehicle. If you continue to drive the vehicle after fatigue, there will be unsafe factors such as drowsiness, inattention, and operation pauses, which will lead to technical problems in traffic accidents. [0003] In order to avoid the user's fatigue driving and when the user experiences fatigue driving, the user is reminded in time. In the prior art, th...
