DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0019] It should be noted that the terms "first", "second" etc. in this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable in appropriate circumstances, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, the process, method, system, product or equipment comprising a series of steps or modules is not necessarily limited to those steps or modules clearly listed, but may include other steps or modules that are not clearly listed or that are inherent to these processes, methods, products or equipment.

[0020] The fatigue driving detection method provided in the embodiment of the present application is applicable to the terminal of the vehicle, which can be various electronic devices with a display screen and supporting web browsing, including but not limited to servers, smart phones, vehicle-mounted devices, tablet computers, laptop portable computers and desktop computers, etc.

[0021] Figure 1 This is one of the flow charts of the fatigue driving detection method provided in the embodiment of the present application, such as Figure 1 As shown, the method includes step 110, step 120 and step 130. The steps of the method flow are only a possible implementation of the present application.

[0022] Step 110: Control the grip force sensor to collect the grip force of the vehicle driver holding the steering control device of the vehicle based on a preset period.

[0023] Specifically, the executor of the fatigue driving detection method provided in the embodiment of the present application is a fatigue driving detection device, which can be a hardware device independently set in the vehicle terminal or a software program running in the vehicle terminal.

[0024] The vehicle is equipped with a camera and a grip force sensor, which are positioned at corresponding locations depending on the vehicle type and structure. The vehicle can be a battery-powered scooter or a car. For example, if the vehicle is a battery-powered scooter, the camera can be placed near the scooter's dashboard, and the grip force sensor can be placed on the handlebars; if the vehicle is a car, the camera can be placed near the onboard display, and the grip force sensor can be placed on the steering wheel.

[0025] The camera primarily captures information about the driver's head and can be an adjustable infrared night vision camera. The steering control device can be a handlebar or steering wheel, depending on the vehicle type. The grip force sensor primarily measures the driver's grip on the vehicle's steering control device.

[0026] A preset period can be set, for example, 30 seconds. When the driver is driving the vehicle, the grip force sensor is controlled to perform grip force detection every 30 seconds.

[0027] Step 120 : When the fluctuation value of the grip force is greater than the preset fluctuation value and / or the grip force is less than the first grip force, control the camera to collect the driver's head information.

[0028] Specifically, if the driver is driving fatigued, the grip force used on the steering control device may fluctuate significantly or be very weak. However, judging whether the driver is driving fatigued based solely on grip force may result in errors. Therefore, when grip force is abnormal (large fluctuations and / or weak grip force), this application further uses information collected by the camera to determine whether the driver is driving fatigued. If grip force is normal, grip force collection continues based on the pre-screening period. The preset fluctuation value and initial grip force can be set based on historical driving data or dynamically adjusted according to actual scenarios.

[0029] The driver's head information may include the driver's head offset and eye closure information.

[0030] When the fluctuation value of the grip force is greater than the preset fluctuation value and the grip force is less than the first grip force, or the fluctuation value of the grip force is greater than the preset fluctuation value and the grip force is less than the first grip force, the camera will be controlled to collect the driver's head information.

[0031] Step 130: If the driver's head information meets the preset fatigue condition, determine that the driver is driving fatigued.

[0032] Specifically, the preset fatigue condition refers to a judgment criterion based on whether the driver's head information reaches a preset threshold.

[0033] If the driver's head information meets the preset fatigue condition, it can be determined that the driver is driving fatigued; if the driver's head information does not meet the preset fatigue condition, the driver should not be driving fatigued at present.

[0034] The fatigue driving detection method provided in the embodiment of the present application controls the grip force sensor to collect the driver's grip force of the steering control device in real time, and further controls the camera to collect the driver's head information when the grip force is abnormal. The driver's head information and preset fatigue conditions are used to timely and accurately determine whether the driver is fatigue driving, thereby improving the accuracy of fatigue driving judgment.

[0035] It should be noted that each implementation method of the present application can be freely combined, the order can be changed, or it can be executed separately, and does not need to rely on or depend on a fixed execution order.

[0036] In some embodiments, step 120 includes: When the fluctuation value of the grip force is greater than the preset fluctuation value and lasts for a first period of time and / or the grip force is less than the first grip force and lasts for a second period of time, the camera is turned on and the driver's head information is collected based on the camera, and the camera includes an infrared night vision camera.

[0037] The head information includes the head offset and eye closure information; the eye closure information includes the eye closure duration and / or the number of eye closures. Step 130 includes: When the head offset is greater than a preset offset and the driver's eye-closing time is greater than a third time, determining that the driver is driving fatigued; or When the head offset is greater than a preset offset and the driver closes his eyes more than a preset number of times, it is determined that the driver is driving fatigued.

[0038] Specifically, when a driver is fatigued, their grip strength will continue to be abnormal, their head will shake, and they will close their eyes for a long time or frequently. Therefore, in this embodiment of the application, the camera is turned on to collect the driver's head information when the grip strength fluctuation value is greater than the preset fluctuation value and lasts for a first time period, the grip strength is less than the first grip strength and lasts for a second time period, or when the grip strength fluctuation value is greater than the preset fluctuation value and lasts for the first time period, and the grip strength is less than the first grip strength and lasts for the second time period.

[0039] If the driver's head offset is greater than the preset offset and the eye-closing time is greater than the third time, or the driver's head offset is greater than the offset and the number of eye closures is greater than the preset number, it can be determined that the driver is currently driving fatigued.

[0040] The first duration, the second duration, the preset offset, the third duration and the number of times the eyes are closed can be set according to historical driving data and / or actual scenarios.

[0041] Figure 2 The second flow chart of the fatigue driving detection method provided in the embodiment of the present application is as follows: Figure 2The driver's grip force sensor measures grip force every 30 seconds while driving. If grip force fluctuations > ±40% for 5 seconds or grip force < 10N for 5 seconds, the camera is activated for real-time video analysis.

[0042] After the camera is turned on, continuous eye tracking for 5 seconds (detecting the length and number of times the eyes are closed) is combined with head offset detection. If the head offset is too large and the eye closure time is too long and / or the number of times the eyes are closed is too many, it is determined that the driver is driving fatigued.

[0043] The fatigue driving detection method provided in the embodiment of the present application equips the vehicle with a grip force sensor and a visual monitoring device (camera) to detect in real time the number of times the driver closes his eyes within a period of time during driving and related data such as his grip force, analyze the driver's driving concentration, and can identify in real time whether the driver is driving fatigued, thereby improving driving safety.

[0044] In some embodiments, after step 130, the method further includes: Generates voice reminders for fatigue driving; Play a reminder voice and adjust the vehicle's current speed.

[0045] Adjusting the current speed of the vehicle includes: If the duration of the reminder voice playback is less than or equal to the fourth duration and the current vehicle speed is greater than the preset speed, the current vehicle speed is reduced in steps until the current vehicle speed is equal to or less than the preset speed or it is detected that the current vehicle speed is accelerating and the grip force is greater than or equal to the second grip force; When it is detected that the current vehicle speed is accelerating and the grip force is greater than or equal to the second grip force, the reminder voice is stopped.

[0046] Play reminder voice and adjust the vehicle's current speed, including: When the playback duration of the reminder voice is greater than the fourth duration and the grip force is less than the second grip force, the current vehicle speed is reduced in steps until the current vehicle speed is equal to zero or it is detected that the current vehicle speed is accelerating and the grip force is greater than or equal to the second grip force.

[0047] Specifically, when it is determined that the driver is driving fatigued, a fatigue warning mechanism will be triggered.

[0048] The fatigue warning mechanism improves driving safety through voice reminders and step-by-step deceleration.

[0049] Step speed reduction means that the vehicle speed is gradually reduced in stages at fixed time intervals (such as every 2 seconds).

[0050] A fatigue driving reminder voice can be generated and played to remind the driver to concentrate on safe driving, while adjusting the vehicle's current speed.

[0051] The adjustment of vehicle speed can be divided into two stages according to the fourth duration.

[0052] The first stage is when the duration of the reminder voice playback is less than or equal to the fourth duration. During this stage, if the current vehicle speed is excessive, such as greater than the preset speed, the vehicle is decelerated in steps until the current speed equals or falls below the preset speed, or the driver is detected accelerating with a grip force greater than or equal to the second grip force during the deceleration process, indicating that the driver is actively driving and their grip force has returned to normal. If the current speed is less than or equal to the preset speed, there is no need to decelerate the current speed. If the driver is detected accelerating with a grip force greater than or equal to the second grip force during the reminder voice playback, indicating that the driver has returned to normal and is no longer fatigued, the reminder voice playback and deceleration control can be stopped.

[0053] The fourth duration, preset vehicle speed, and second grip strength can be set according to actual scenarios.

[0054] For example, while the reminder voice is playing, the vehicle is decelerated in steps, with the speed decreasing by 15% every 2 seconds. The preset vehicle speed may be 40% power. When the driver actively accelerates and the grip strength returns to normal (second grip strength), the reminder voice is stopped and the step-by-step deceleration control is stopped, and the fatigue warning mechanism is exited.

[0055] If after the first stage ends, that is, after the reminder voice is played for the fourth time, the grip strength is still less than the second grip strength, that is, the grip strength has not returned to the normal value, indicating that the current driver may still be driving fatigued, then enter the second stage.

[0056] The second stage is the stage where the playback duration of the reminder voice is greater than the fourth duration. In the second stage, the reminder voice will continue to be played and the current vehicle speed will be reduced in steps until the current vehicle speed is equal to zero. Or, if during the deceleration process, it is found that the driver is accelerating and the grip force is greater than or equal to the second grip force, the step-by-step deceleration will be stopped and the control of the step-by-step deceleration will be stopped, and the fatigue warning mechanism will be exited.

[0057] If the current vehicle speed is reduced step by step to zero, the driver needs to unlock the vehicle at the vehicle terminal before continuing to drive.

[0058] For example, the fourth time duration is 30 seconds, and the vehicle terminal is the driver's mobile phone. If the grip force does not return to normal within 30 seconds of the reminder voice playback, the vehicle continues to decelerate step by step to 0, and the driver needs to actively unlock the vehicle on the mobile phone before continuing to drive.

[0059] The fatigue driving detection method provided in the embodiment of the present application ensures the driver's driving safety and effectively prevents fatigue driving accidents by implementing safety intervention measures such as voice reminders or forced deceleration in a graded manner when the driver is in a fatigue driving state. It can also provide data support for platform safety management and reduce operational risks.
