[0046] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0047] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0048] The main solution of the embodiment of the present application is: by collecting the driver's eye image information and facial image information; determining the driver's fatigue level based on the eye image information and the facial image information; generating a fatigue relief plan based on the driver's fatigue level and applying multi-sensory stimulation to the driver according to the fatigue relief plan.

[0049] In this embodiment, for the convenience of description, the following description is made by taking the identification of the onboard computer as the execution subject.

[0050] In the prior art, drivers will inevitably feel tired or sleepy while driving. If such fatigue and sleepiness cannot be relieved in time, it will have a serious impact on the driver's reaction speed, judgment ability and operation accuracy, thus posing a threat to driving safety. Therefore, how to effectively relieve the driver's fatigue without distracting the driver's attention is a technical problem that needs to be solved urgently.

[0051] The present application provides a solution, through which the driver's fatigue level is determined based on data such as the driver's eye and facial movements, and then the driver is stimulated through multiple senses, thereby effectively alleviating the driver's fatigue level and improving driving safety without distracting the driver's attention.

[0052] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle-mounted computer, etc. The following takes the vehicle-mounted computer as an example to illustrate this embodiment and the following embodiments.

[0053] Based on this, the embodiment of the present application provides a method for alleviating driver fatigue, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the driver fatigue relief method of the present application.

[0054] In this embodiment, the driver fatigue relief method includes steps S10 to S30:

[0055] Step S10, collecting eye image information and facial image information of the driver;

[0056] It should be noted that the solution of this embodiment relies on various units in the vehicle: a. Sensor module: This module is equipped with advanced eye tracking cameras and facial recognition cameras, which can accurately capture the driver's eye activity blinking frequency, facial expressions and other physiological indicators, which are used as an important basis for judging the driver's fatigue level; b. Environmental control system: This system has functions such as temperature regulation, air circulation and fragrance release. It can intelligently adjust the temperature, humidity and smell in the cabin according to the data provided by the sensor module to create a comfortable and pleasant driving environment, which helps to reduce the driver's fatigue; c. Seat vibration system: A vibrator is embedded in the seat, which can vibrate at different frequencies and intensities according to the preset mode, imitate the massage effect, effectively relax the driver's body muscles, and reduce the physical fatigue caused by long-term driving; d. Sound stimulation system: Use the car's audio system to play specially selected music with strong beats and fast rhythms to relieve the driver's fatigue and distress; e. Visual prompt system: By adjusting the color and brightness of the interior ambient light, a warm and comfortable visual effect is created, which helps to reduce the driver's visual fatigue and enhance the driving experience. f. Central Processing Unit: The central processing unit is responsible for receiving and analyzing data from the sensor module, developing a personalized fatigue relief plan based on the driver's fatigue level and personal preferences, and coordinating the operation of various subsystems.

[0057] It should be understood that first, the driver's eye images and facial images are respectively collected by the image acquisition device and the sensor to determine the driver's fatigue level. After the system is started, the sensor module in the cockpit immediately enters the working state and is ready to start monitoring.

[0058] Step S20, determining the driver's fatigue level according to the eye image information and the facial image information;

[0059] In a specific implementation, after obtaining the eye image information, the eye movement pattern and abnormal blinking information are determined according to the eye image information, and then the facial muscle activity information is determined according to the facial image information, and finally the driver's fatigue level can be assessed.

[0060] In a feasible implementation, in order to accurately determine the driver's fatigue level, step S20 includes: determining the eye movement pattern and abnormal blinking information based on the eye image information; determining the facial muscle activity information based on the facial image information; determining the driver's fatigue level based on the eye movement pattern, the abnormal blinking information and the facial muscle activity information.

[0061] It should be noted that first, it is necessary to analyze the driver's eye activities and related record information of blinking activities based on the eye image information, from which the eye movement pattern and abnormal blinking information can be obtained, and then the image of the driver's facial muscles is determined based on the facial image information, thereby determining the facial muscle activity information, and finally the eye movement pattern, abnormal blinking information and facial muscle activity information are combined to determine the driver's fatigue level.

[0062] It will be appreciated that the driver's facial muscle activity is analyzed to identify whether there is frequent yawning, frowning, or other expressions that indicate fatigue.

[0063] In a specific implementation, the above-mentioned monitored eye movement patterns, blinking frequency and facial expression data are integrated to form a comprehensive indicator of the driver's fatigue level, and the central processing unit divides it into different levels based on the integrated data.

[0064] In a feasible implementation, in order to be able to determine abnormal blinking information and eye movement patterns based on more eye parameters, the step of determining eye movement patterns and abnormal blinking information according to the eye image information includes: determining eye movement trajectory, eye gaze point information and scanning speed according to the eye image information; determining eye movement patterns according to the eye movement trajectory, scanning eye gaze point information and the scanning speed; determining the number of blinks information according to the eye image information; and obtaining abnormal blinking information by evaluating the number of blinks information.

[0065] It should be noted that, first, the eye tracking camera captures the driver's eye movement trajectory, records the changes in the eye gaze point and the scanning speed; the facial recognition camera records the number of times the driver blinks, calculates the frequency of blinking, and evaluates whether there is excessive blinking or heavy eyelids as abnormal blinking information.

[0066] Step S30, generating a fatigue relief plan according to the driver's fatigue level and applying multi-sensory stimulation to the driver according to the fatigue relief plan.

[0067] It should be understood that after determining the driver's fatigue level, the central processor automatically generates a fatigue relief plan based on the driver's previously set personal preferences, such as favorite music type, comfortable temperature range, preferred massage intensity, etc.

[0068] In a feasible implementation, in order to continuously update the fatigue relief plan, step S30 includes: monitoring the driver's physiological response information, and determining fatigue level change information based on the physiological response information; and updating the fatigue relief plan based on the fatigue level change information.

[0069] In specific implementation, continuous monitoring and adjustment: 1) The system continuously monitors the driver's physiological reactions and changes in fatigue levels, including new eye movement data, blinking frequency and facial expressions; 2) The central processing unit analyzes the newly collected data in real time to evaluate the effectiveness of the current stimulation program; 3) If it is detected that the fatigue level has not decreased or has increased, the central processing unit will dynamically adjust the stimulation program based on real-time data, which may increase the intensity of massage, change music tracks or adjust the color of lights; 4) The system continuously cycles the process of monitoring, analysis and adjustment to ensure that the most effective fatigue relief measures are always provided until the driver's fatigue state is improved; 5) Once it is detected that the driver's fatigue level has dropped to a safe level, the system will gradually reduce or stop the stimulation and return to normal monitoring status.

[0070] It should be noted that, through the steps of the present embodiment, the driver fatigue relief system can effectively relieve the driver's fatigue level and improve driving safety without distracting the driver's attention.

[0071] This embodiment provides a method for relieving driver fatigue, which collects the driver's eye image information and facial image information; determines the driver's fatigue level according to the eye image information and the facial image information; generates a fatigue relief plan according to the driver's fatigue level and applies multi-sensory stimulation to the driver according to the fatigue relief plan. In this way, the driver's fatigue level is determined based on data such as the driver's eye and facial movements, and then the driver is stimulated through multiple senses, thereby effectively relieving the driver's fatigue level and improving driving safety without distracting the driver's attention.

[0072] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S30 includes steps S301 to S302:

[0073] Step S301, determining a fatigue stimulation mode and fatigue stimulation intensity according to the driver's fatigue level, wherein the fatigue stimulation mode includes at least one of temperature adjustment, seat vibration, sound stimulation and visual stimulation;

[0074] It should be noted that the fatigue stimulation mode is first determined according to the driver's fatigue level, that is, at least one of temperature adjustment, seat vibration, sound stimulation and visual stimulation is determined as the fatigue stimulation mode. After the fatigue stimulation mode is determined, the intensity corresponding to each corresponding fatigue stimulation mode is determined.

[0075] In a feasible implementation manner, in order to accurately determine the fatigue stimulation mode and fatigue stimulation intensity, step S301 includes: determining the cabin target temperature, seat massage mode, sound stimulation music and interior lighting color according to the driver's fatigue level; determining the fatigue stimulation mode according to the cabin target temperature, seat massage mode, sound stimulation music and interior lighting color; determining the fatigue stimulation intensity according to the fatigue stimulation mode.

[0076] It should be understood that the implementation of stimulation mainly includes four ways: environmental control, seat vibration, sound stimulation, and visual stimulation. The environmental control system will adjust the cabin temperature to an appropriate level according to the plan, start or enhance air circulation, and release refreshing fragrance; the seat vibration system will start a specific mode of massage according to the plan settings, such as wave or tapping, to relax the driver's body muscles; the sound stimulation system plays strong rhythm music preferred by the driver to help the driver refresh himself; the visual prompt system adjusts the color and brightness of the interior ambient light, which may change to soft blue or green, to create a quiet visual environment and reduce visual fatigue.

[0077] In a feasible implementation, in order to determine the stimulation intensity, the step of determining the fatigue stimulation intensity according to the fatigue stimulation mode includes: determining the fatigue stimulation level according to the fatigue stimulation mode; determining the fatigue stimulation intensity according to the fatigue stimulation level and a preset stimulation gear.

[0078] In the specific implementation, each stimulus will be divided into 5 levels according to the severity of the stimulus: light, relatively light, normal, relatively heavy, and heavy; the environmental control system will be divided into 5 corresponding levels according to the temperature and air volume of the vehicle air conditioner. The seat control system will divide the vibration of the seat into 5 levels from the lightest to the strongest. The sound stimulation system divides the audio volume from 0 to 70% into 5 levels to avoid scaring the driver due to excessive volume. The visual prompt system divides the brightness of the interior ambient light from off to maximum into 5 levels. The multi-sensory stimulation system implements different levels of stimulation according to the different fatigue levels of the driver.

[0079] Step S302: generating a fatigue relief plan according to the fatigue stimulation mode and the fatigue stimulation intensity, and performing multi-sensory stimulation on the driver according to the fatigue relief plan.

[0080] It should be noted that after determining the fatigue stimulation mode and fatigue stimulation intensity, a complete fatigue relief plan is generated, and then arranged and generated by the central processing unit to achieve multi-sensory stimulation of the driver to reduce the fatigue level.

[0081] This embodiment determines the fatigue stimulation mode and fatigue stimulation intensity according to the driver's fatigue level, and the fatigue stimulation mode includes at least one of temperature adjustment, seat vibration, sound stimulation and visual stimulation; generates a fatigue relief plan according to the fatigue stimulation mode and the fatigue stimulation intensity, and applies multi-sensory stimulation to the driver according to the fatigue relief plan. In this way, a non-invasive multi-sensory stimulation method is adopted, avoiding the discomfort or risks that may be caused by electrical stimulation, and all stimulation methods are carried out without affecting the driver's attention, ensuring driving safety. Through the simultaneous stimulation of multiple senses, the system can relieve the driver's fatigue more quickly and more comprehensively.

[0082] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the driver fatigue relief method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
