[0002] In the current technology, camping is a short-term outdoor lifestyle, and more and more people are choosing to go camping by car during their leisure time. Camping is usually an organized and planned form of tourism, with self-driving as the main mode of transportation. However, self-driving camping often requires long driving hours, and sleep during the camping process cannot be guaranteed. Therefore, in order to ensure driving safety during self-driving camping, it is essential to conduct reasonable fatigue monitoring for drivers. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a method, device, electronic device and storage medium for monitoring fatigue driving, so as to reasonably monitor fatigue driving of drivers after camping.

[0004] Firstly, this application provides a method for monitoring fatigued driving.

[0007] Preferably, the total sleep duration of the target user is determined by the following methods: determining the time the target user falls asleep in the campervan after arriving at the camping destination, and determining the corresponding wake-up time after falling asleep in the campervan; determining the total sleep duration of the target user based on the difference between the wake-up time and the sleep time; or determining the arrival time of the campervan at the camping destination, and determining the start time of the campervan's current journey; determining the total sleep duration of the target user based on the departure time and arrival time; or determining the arrival time of the campervan at the camping destination, determining the departure time of the campervan's current journey, and determining the total usage time of the campervan's onboard system; determining the total sleep duration of the target user based on the departure time, arrival time, and the total usage time of the onboard system.

[0008] Preferably, the fatigue driving risk levels include fatigue driving risk level 1, fatigue driving risk level 2, and fatigue driving risk level 3.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. Based on the embodiments of this application, every other embodiment obtained by those skilled in the art without inventive effort falls within the scope of protection of this application.

[0026] First, the applicable scenarios for this application will be introduced. This application can be applied to fatigue driving monitoring after camping.

[0027] Based on this, embodiments of this application provide a method, device, electronic device, and storage medium for monitoring fatigued driving.

[0028] Please see Figure 1 , Figure 1 This is a flowchart illustrating a fatigue driving monitoring method provided in an embodiment of this application. Figure 1 As shown in the embodiment of this application, the method for monitoring fatigued driving includes the following steps:

[0029] S101. Respond to the driver monitoring system activation command and obtain the most recent sleep information of the target user currently driving the camping vehicle. The sleep information includes at least the total sleep duration of the target user between the time the camping vehicle arrives at the camping destination and the time the camping vehicle is driven this time.

[0030] The driver monitoring system here is specifically a Driver Monitoring System (DMS), a real-time system that determines the driver's state based on facial images, physiological indicators, or vehicle information processing. Its main functions include driver identification, fatigue monitoring, distraction monitoring, and monitoring of dangerous driving behaviors (such as drunk driving, using a mobile phone while driving, and drinking water). The activation command for the driver monitoring system can be automatically generated after the vehicle's main control system is powered on, or it can be generated after the driver manually selects to activate the fatigue driving monitoring function via the in-vehicle screen.

[0031] The camping vehicles here can be motorhomes or off-road vehicles, or regular vehicles.

[0032] Specifically, the total sleep duration of the target user is determined using the following methods:

[0033] Determine the target user's sleep time inside the campervan after arriving at the camping destination, and determine the corresponding wake-up time after the target user falls asleep inside the campervan. Based on the difference between the wake-up time and the sleep time, determine the target user's total sleep duration.

[0034] Based on the sleep information of target users, image data collected by cameras installed on the campervan can be used to identify the target user's sleep duration, activity duration, etc., and then calculate the target user's total sleep duration. The sleep time here is the difference between the wake-up time and the sleep time, which can be determined based on the alarm clock setting in the in-vehicle system, or based on the time it takes for the seat backs in the campervan to recline and unfold.

[0035] Alternatively, it can determine the arrival time of the campervan at the camping destination and the start time of the campervan's journey. Based on the departure and arrival times, the total sleep duration of the target users can be determined.

[0036] Alternatively, the arrival time of the campervan at the camping destination, the departure time of the campervan's current journey, and the total usage time of the campervan's onboard system can be determined. Based on the departure time, arrival time, and total usage time of the onboard system, the total sleep time of the target user can be determined.

[0037] In one scenario, a user's sleep duration can be predicted based on the total camping time. For example, if a user arrives at destination A at 10:00 AM on the 8th, and then starts their campervan at 9:00 AM on the 9th, driving away from destination A to the next destination B or back to the starting point C, the total sleep duration between 9:00 AM on the 9th and 10:00 PM on the 8th can be assumed to be the target user's total sleep duration. Alternatively, the total sleep duration can be determined based on the user's historical sleep settings recorded by the vehicle's main control system.

[0038] That's acceptable. The statistics show the user stayed at destination A for 23 hours, and the total usage time of the in-vehicle system was detected to be 11 hours. Therefore, the target user's total sleep time is determined to be 23 - 11 = 12 hours. Here, the total usage time of the in-vehicle system can be the time between the user's first and last operation of the vehicle's central control system while staying at destination A.

[0039] Furthermore, when data is collected on target users getting up at night, the duration of nighttime urination needs to be removed from the determined sleep duration.

[0040] S102. Based on sleep information, determine the preset level of fatigue driving monitoring for the target user.

[0041] In step S102, based on the target user's most recent total sleep duration, a preliminary prediction can be made of the target user's physiological condition, such as attention and fatigue level, thereby determining the likelihood of the target user exhibiting fatigued driving behavior while currently driving the camping vehicle, and evaluating the corresponding level.

[0042] For example, if the target user's total sleep duration the previous night was 10 hours, it indicates that the target user slept well, and the preset level can be the lower first level. If the target user's total sleep duration the previous night was 7 hours, the preset level can be the second level. If the target user's total sleep duration the previous night was 4 hours, the preset level can be the higher third level.

[0043] S103. Based on the preset level of fatigue driving monitoring, determine the corresponding target fatigue driving monitoring scheme as the initial fatigue driving monitoring scheme after the driver monitoring system of the camping vehicle is started and execute it. The fatigue driving monitoring scheme is used to monitor the fatigue driving of the driver of the camping vehicle.

[0044] Each preset level has at least one preset fatigue driving monitoring scheme, and the fatigue driving monitoring schemes corresponding to different preset levels are different. When the preset level is lower, the sensitivity of the fatigue driving monitoring scheme to fatigue driving detection is also lower.

[0045] For example, the fatigue driving detection scheme corresponding to the first level can monitor the blinking frequency of the target user. If the blinking frequency of the target user exceeds a first preset blinking frequency, it is determined that the target user is driving while fatigued. At this time, the fatigue driving detection scheme corresponding to the second level can also monitor the blinking frequency of the target user while simultaneously making a judgment based on multiple features such as the target user's attention span, facial orientation, and yawning frequency.

[0046] This application predicts the attention and fatigue levels of target users based on their sleep information, thereby selecting different fatigue driving monitoring schemes. This improves the accuracy and relevance of the fatigue driving monitoring schemes executed by the driver monitoring system, resulting in more accurate fatigue driving monitoring results and timely reminders to drivers to improve their driving behavior and ensure driving safety.

[0047] Please see Figure 2 , Figure 2 A flowchart illustrating another method for monitoring fatigued driving provided in this application embodiment. In one embodiment of this application, the method for monitoring fatigued driving further includes:

[0048] S104. Based on the fatigue driving monitoring scheme currently being implemented in the camping vehicle, output the fatigue driving monitoring results for the target user.

[0049] Specifically, this also includes determining a new fatigue driving monitoring scheme based on the target user's real-time fatigue driving risk level and updating it to the fatigue driving monitoring scheme currently being implemented in the camping vehicle.

[0050] It is understandable that the driver monitoring system can be activated simultaneously with the start of the camper vehicle. Based on the corresponding fatigue driving monitoring protocol, the system outputs fatigue driving monitoring results at preset time intervals. In other words, the fatigue driving monitoring protocol executed by the driver monitoring system can be updated in real time.

[0051] The results of fatigue driving monitoring here can be the presence or absence of fatigue driving behavior, or the fatigue level of fatigue driving behavior or the index value indicating the degree of fatigue.

[0052] S105. Based on the fatigue driving monitoring results of the target user, determine the real-time fatigue driving risk level of the target user.

[0053] Since the more fatigued a driver is, the more risky driving becomes, the higher the fatigue level of the target user, the higher the corresponding fatigue driving risk level.

[0054] S106. Implement safe driving reminder measures corresponding to the real-time fatigue driving risk level of the target user to remind the users in the campervan that the driver is driving while fatigued.

[0055] This allows for the implementation of different safe driving reminders based on the target user's varying level of fatigue driving risk.

[0056] By implementing safe driving reminder measures corresponding to the level of fatigue driving risk, the driver or other users in the campervan can be promptly alerted that the driver is driving while fatigued and that the driver's behavior needs to be improved to ensure driving safety.

[0057] In one embodiment of this application, the fatigue driving risk levels include fatigue driving risk level one, fatigue driving risk level two, and fatigue driving risk level three. When the fatigue driving risk level is fatigue driving risk level one, the corresponding safe driving reminder measures include:

[0058] Stop executing the steps of determining a new fatigue driving monitoring plan based on the target user's real-time fatigue driving risk level and updating the fatigue driving monitoring plan executed on camping vehicles.

[0059] In the case of Level 1 fatigue driving risk, the fatigue driving monitoring scheme executed by the driver monitoring system can remain the initial fatigue driving monitoring scheme determined based on the sleep information of the target user, and there is no need to update the executed fatigue driving monitoring scheme.

[0060] Specifically, the fatigue driving monitoring solution uses image data collected by target sensors on camping vehicles to identify and determine the number of times the target user performs preset behaviors. Based on the ratio of the preset behavior count to the calibrated count, a fatigue driving monitoring result is generated. When the fatigue driving risk level is level two, the corresponding safe driving reminder measures include:

[0061] Increase the number of calibrations. Also, issue safe driving reminders via voice or text at the first preset time interval.

[0062] For example, the fatigue driving detection scheme corresponding to the first level can monitor the blinking frequency of the target user. If the blinking frequency of the target user exceeds a first preset blinking frequency, it is determined that the target user is driving while fatigued. The fatigue driving detection scheme corresponding to the second level can monitor the blinking frequency of the target user. If the blinking frequency of the target user exceeds a second preset blinking frequency, it is determined that the target user is driving while fatigued. The second preset blinking frequency is less than the first preset blinking frequency. Here, the corresponding preset blinking frequency can be set from 15 to a maximum value of 20.

[0063] It can also provide safety reminders to users to take a break every 3 hours, either via voice or by displaying them on the central control screen.

[0064] Specifically, when the fatigue driving risk level is Level 3, the corresponding safe driving reminder measures include:

[0065] Increase the number of calibrations. Also, issue safe driving reminders via voice or text at a second preset time interval, where the second preset time interval is shorter than the first preset time interval. Additionally, adjust the driving environment inside the campervan, including one or more of the following adjustments: controlling driver's seat vibration, switching to autonomous driving mode, turning on the vehicle's air conditioning, playing audio, increasing audio volume, and turning on the vehicle's fragrance diffuser.

[0066] Compared to Level 2 fatigue driving risk, Level 3 fatigue driving risk corresponds to stronger safety driving reminders.

[0067] For example, a safety reminder to take a break could be sent to the user every 2 hours. The system could also provide the user with the location of the nearest rest area and navigation, allowing the driver to rest and cease driving.

[0068] Based on the same inventive concept, this application also provides a fatigue driving monitoring device corresponding to the fatigue driving monitoring method. Since the principle of the device in this application is similar to the fatigue driving monitoring method described above, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be described again.
