Problems solved by technology

The scheme should not only consider the conditions of the road environment (curves, slopes, etc.), but also take into account the different driving habits of different drivers in the road environment. It is difficult to conclude that the driver's unreasonable operation behavior is related to fatigue driving. , there are many factors to consider, and it is difficult to realize

Embodiment 1

[0039] see figure 1 , is a schematic flowchart of a method for preventing fatigue driving provided by Embodiment 1 of the present invention. Present embodiment 1 specifically comprises the following steps:

[0040] S1. Recognize the face of the driver in the cab through three-dimensional infrared face recognition technology, so as to obtain the face data of the driver;

[0041] S2. When the speed of the car exceeds the preset speed and the data signal that the seat in the driver's cab is occupied is recognized, it is judged that the car is in the driving state;

[0042] S3. Recording the acquired driver's face data indicates the time when the car is continuously in the driving state for the same driver;

[0043] S4. When the car is continuously in the driving state for more than the preset first normal driving time, start the preset active safety control mode.

[0044] In this embodiment, the identity of the driver is determined by using the three-dimensional infrared face ...

Embodiment 3

[0062] see image 3 , is a schematic structural diagram of a system for preventing fatigue driving provided by Embodiment 3 of the present invention. Present embodiment 3 specifically comprises the following steps:

[0063] Facial data acquisition unit 1 is used to identify the driver's face in the cab through three-dimensional infrared face recognition technology, thereby obtaining the driver's facial data;

[0064] The driving state judging unit 2 is used to judge that the car is in the driving state when the speed of the car exceeds the preset speed and recognizes the data signal that the seat of the driver's cab is occupied;

[0065] The driving time recording unit 3 is used to record the time when the driver's face data acquired represents the same driver and the car continues to be in the driving state;

[0066] The safety control starting unit 4 is used to start the preset active safety control mode when the car is continuously in the driving state for more than the p...

Embodiment 4

[0079] see Figure 4 , is a schematic structural diagram of a system for preventing fatigue driving provided by Embodiment 4 of the present invention. Wherein, the specific structure of the present embodiment 4 includes the face data acquisition unit 1 provided by the embodiment 3 of the present invention, the driving state judgment unit 2, the driving time recording unit 3 and the safety control starting unit 4, and the specific implementation method can refer to the implementation The content of Example 3 will not be repeated here. And present embodiment 4 also comprises in addition:

[0080] The safety control stop unit 5 is used to record the time when the car is turned off and stopped after the safety control start unit 4 starts the preset active safety control mode and obtains the signal of turning off the car to stop;

[0081] If the time for the car to be turned off and stopped exceeds the preset rest time, the start of the preset active safety control mode will be s...

Abstract

The invention discloses a method for preventing fatigue driving, which comprises the steps of recognizing the face of a driver in a driving cab through a three-dimensional infrared face recognition technology so as to acquire face data of the driver; judging an automobile stays at a driving state when the speed of the automobile exceeds the preset speed and data signals indicating that a seat of the driving cab is occupied are recognized; recording the time during which the automobile continuously stays at the driving state when the acquired face data of the driver represents the same driver; and starting a preset active safety control mode when the time during which the automobile continuously stays at the driving state exceeds first preset normal driving time. Correspondingly, the invention further provides a system for preventing fatigue driving.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a method and system for preventing fatigue driving. Background technique [0002] Fatigue driving refers to the phenomenon that the driver's physiological function and psychological function are out of balance after driving continuously for a long time, and the driving skill declines objectively. The following are several existing technologies for detecting fatigue driving and their deficiencies: [0003] 1. Detect fatigue by collecting images of the driver's head. This solution may face problems with large environmental differences, such as direct sunlight, reflections from glasses, wearing sunglasses, etc., and it cannot avoid the interference of light sources from various directions on the lens, especially at night when the light is dark. Secondly, due to the large individual differences, the reliability of the recognition results is not high. [0004] 2. Collect the driver...
