[0037] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0038] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0039] In recent years, as commercial vehicles have been running for a long time and at high intensity, the problem of driver fatigue has become increasingly prominent, seriously affecting traffic safety. To meet this challenge, a variety of commercial vehicle driver monitoring systems (DMS) have been developed on the market to detect the driver's fatigue status in a timely manner and issue an alarm. However, existing DMS systems usually remind drivers through sound and light alarms. Although this reminder method can awaken the driver's attention to a certain extent, it also has some significant shortcomings.

[0040] First, the accuracy of the sound and light alarms makes the system prone to false alarms. False alarms may cause trouble to the driver, especially when driving for a long time. Frequent false alarms will increase the driver's irritability and affect his driving experience. Many drivers even choose to turn off the DMS system to avoid frequent false alarms, thus losing the DMS system's protective effect on fatigue detection.

[0041] Secondly, the current sound and light alarm method cannot provide differentiated reminders based on the degree of fatigue. Drivers may need different intensities of wake-up methods at different levels of fatigue, but the existing system usually uses a single alarm method, which cannot make the driver feel the different levels of fatigue physiologically. In other words, the existing system lacks a personalized and progressive reminder mechanism and cannot achieve effective fatigue classification management. This deficiency makes the alarm experience relatively monotonous and cannot form an effective reminder for the driver.

[0042] In the prior art, two people usually take turns driving and resting during long-distance driving. If sound and light alarms are used, the driver who is resting may be affected, that is, the driver who is not driving will also be reminded. After multiple turns of driving and fatigue reminders, the driver may be confused and ignore the sound and light alarms.

[0043] In order to solve the above problems, developing a more intelligent and personalized fatigue detection system that can provide appropriate and timely reminders based on the driver's fatigue level has become an urgent technical issue to be solved. The development of this technology will be of great significance to improving the driving safety of commercial vehicles and improving the driving experience.

[0044] To achieve the above purposes and other related purposes, such as Figure 1 , 2As shown, the present invention provides a fatigue driving reminder system, which is applied to a vehicle and includes a sensing unit 10, a control unit 20 and a lifting device 30.

[0045] The sensing unit 10 is used to detect the driver's fatigue state lifting device 30. The sensing unit 10 includes a camera 11 facing the driver's face. The sensing unit 10 uses an infrared light with a wavelength of 940nm to clearly capture facial features in low-light or even no-light environments. Compared with ordinary cameras 11 that rely on natural light, the infrared camera 11 can still maintain high-precision detection in dark light environments such as night or tunnels, ensuring that the monitoring of fatigue status is not interrupted. The active infrared camera 11 illuminates the face with infrared light of a specific wavelength, and then the infrared sensor collects the reflected signal, effectively avoiding the interference of external ambient light. Whether in strong light or weak light conditions, the sensing unit 10 can stably obtain facial information and improve the detection reliability of the system. The infrared camera 11 realizes non-contact fatigue detection, and the driver does not need to wear additional equipment, avoiding the trouble and discomfort of wearing a sensor. The design of the camera 11 is more acceptable to the driver and will not affect the driver's normal vision and driving habits. The system uses an infrared sensor to collect infrared light data reflected by the face in real time, images it through the ISP module, and outputs it to the control unit 20 for real-time processing. Real-time data processing ensures that the system can respond quickly to the driver's fatigue state and improve the timeliness and effectiveness of reminders.

[0046] The control unit 20 is connected to the sensing unit 10 for communication, and the control unit 20 is used to generate control information according to the fatigue state. The control unit 20 is composed of an image algorithm unit and a control algorithm unit. The image algorithm unit focuses on processing image data from infrared sensors, and analyzes the driver's facial features (such as blinking frequency, gaze direction, eye closure time, etc.) through advanced image algorithms to accurately determine the driver's fatigue state and give a corresponding fatigue level. Through multi-dimensional image information, the system can more accurately detect different degrees of fatigue, avoid false alarms, and ensure the reminder effect. The control algorithm unit dynamically controls the degree of seat lifting and lowering and the target height according to the fatigue level and the real-time status of the vehicle (vehicle speed, brake signal, acceleration signal, etc.). In the case of slight fatigue, the system can be set to a slight seat lifting and lowering, which plays a gentle reminder role; in the case of severe fatigue, the seat will rise and fall significantly, strongly reminding the driver. This hierarchical reminder method realizes the personalization of reminders, allowing the driver to intuitively feel the degree of fatigue and improve the awakening effect. The control algorithm effectively judges the current driving state by integrating various signal data such as vehicle speed, brake, acceleration, etc., to avoid false triggering of seat lifting reminders during sensitive operations such as sudden acceleration and sudden braking. This function not only reduces the interference of false alarms to the driver, but also ensures that the system provides reminders at the appropriate time to ensure driving safety.

[0047] The lifting device 30 is arranged on the main driving seat of the vehicle, and the lifting device 30 is connected to the control unit 20 in communication. The lifting device 30 is used to lift the main driving seat according to the control information. The lifting device 30 adjusts the height of the main driving seat in real time by receiving the control information sent by the control unit 20. According to the degree of fatigue of the driver, the seat can be slightly or drastically lifted and lowered, providing a physical stimulation, effectively awakening the driver's attention, and reducing the risk of fatigue driving. According to the control information generated by the control unit 20, the lifting device 30 can realize graded reminders-for example, providing a mild seat adjustment in a slightly fatigued state, and performing a significant lifting and lowering in a severely fatigued state, achieving different degrees of reminder effects. This personalized adjustment can not only effectively remind the driver, but also ensure the comfort of the driving process. The lifting device 30 is only arranged on the main driving seat, so that the reminder measures are only effective for the main driver and will not affect the co-driver who is resting. This design avoids the interference problem of traditional sound and light alarms, ensures the rest quality of the co-driver, and makes it more efficient and safe for two people to drive in turns. The lifting device 30 is precisely controlled by the control unit 20 and can provide progressive reminders. For example, when the fatigue state increases, the seat lifting range is gradually increased, so that the driver can perceive the fatigue signal unconsciously and gradually regain alertness. This gradual awakening method is more in line with human physiological habits and improves the user experience of the system.

[0048] like Figure 1 As shown, the lifting device 30 includes an air storage unit 31 and an air spring 32 arranged on the main driver's seat, an intake pipeline 33 and an exhaust pipeline 34 are arranged on the air spring 32, the intake pipeline 33 is connected with the air storage unit 31, and an air valve 35 is arranged on the intake pipeline 33 and the exhaust pipeline 34. The air valve 35 is communicated with the control unit 20, and the air valve 35 is used to open or close according to the control information.

[0049] The air storage unit 31 is composed of an air tank and an air pump. The air valve 35 is a solenoid valve. The air valve 35 is accurately opened or closed according to the control information sent by the control unit 20, and quickly controls the inflation or exhaust of the air spring 32. Through this rapid response mechanism, the system can immediately start the seat lifting and lowering at the moment of detecting the driver's fatigue state, effectively reminding the driver. The main driver's seat is a common air spring seat for commercial vehicles. The air spring seat is equipped with an air spring 32 system, which makes full use of this existing structure, not only reducing the cost of hardware development and modification, but also reducing the installation complexity of new components. This design greatly reduces the system cost and improves the economy, and is suitable for widespread promotion and application in commercial vehicles. The suspended seat is a commonly used commercial vehicle seat. The suspended seat itself has an air spring 32, which can effectively reduce costs.

[0050] The longitudinal acceleration generated during the lifting and lowering of the air spring 32 will make the driver feel a slight sense of loss of control, providing strong physical stimulation, allowing the driver to quickly recover his attention from a state of fatigue. Especially in a state of severe fatigue, this "sense of loss of control" reminder method can effectively wake up the driver and prevent further fatigue. Through the control of the air valve 35 on the intake and exhaust pipes 34, the system can accurately adjust the inflation volume of the air spring 32 to achieve different lifting amplitudes and frequencies, and provide a graded reminder effect. In the case of mild fatigue, the system can only perform slight lifting and lowering to avoid discomfort to the driver; in the case of severe fatigue, the reminder intensity can be increased to achieve the best wake-up effect.

[0051] like Figure 1 As shown, the control unit 20 is connected to the bus 40 (CAN) of the vehicle in communication, and the control unit 20 is used to generate the control information according to the speed signal, brake signal and acceleration signal in the bus 40. Through the communication connection with the bus 40, the control unit 20 can monitor the speed, brake and acceleration signals of the vehicle in real time. The signal changes under different driving conditions are directly fed back to the control unit 20 to ensure that the system can dynamically adjust the reminder strategy according to the actual driving conditions. For example, when the vehicle is driving at high speed or accelerating suddenly, the system will increase the reminder frequency according to the risk factor to ensure the safety of the driver. The control unit 20 uses the vehicle signal as an important basis to comprehensively judge the driver's fatigue state and driving environment. For example, if a brake signal is detected, the control unit 20 can temporarily turn off the seat lifting reminder to avoid unnecessary interference to the driver during emergency stop or acceleration. This judgment method based on multiple signals reduces false triggering and improves the intelligence of the reminder system.

[0052] like Figure 3 As shown, the present invention also provides a fatigue driving reminder method, which is applied to the fatigue driving reminder system as mentioned above, and includes the following steps:

[0053] S1. Obtain the driver's fatigue state through the perception unit 10, and obtain the vehicle speed signal, brake signal and acceleration signal in the vehicle bus 40. In this way, the actual state of the driver can be judged more comprehensively and accurately. This multi-signal fusion mode combines subjective (driver status) and objective (vehicle signal) data to ensure that the system can respond flexibly in various driving environments. By sensing the driver's fatigue state and combining the vehicle's current speed, braking and acceleration behavior, the system can comprehensively judge the fatigue risk. For example, when it is detected that the driver has signs of fatigue and the vehicle speed is high, the system will promptly increase the reminder to prompt the driver to improve his attention and reduce the safety hazards caused by fatigue.

[0054] S2. Generate the control information according to the vehicle speed signal, the brake signal, the acceleration signal and the fatigue state.

[0055] When the vehicle speed in the vehicle speed signal is less than or equal to the preset threshold value (15km / h), the control information is that the lifting device 30 does not move. When the speed in the vehicle speed signal is lower than or equal to the preset threshold value (such as low-speed driving, traffic jam or parking), the control information will be set to the lifting device 30 does not move. This can effectively avoid reminders at low speeds, reduce unnecessary interference, and allow the driver to maintain a quiet driving experience at low speeds.

[0056] When the brake signal is obtained, the control information is that the lifting device 30 does not move. This is to avoid distraction or discomfort caused by the lifting of the seat during emergency braking or deceleration, ensure that the driver can focus on the braking operation, and further improve driving safety.

[0057] When the acceleration signal is obtained, the control information is that the lifting device 30 does not move. This avoids additional physical interference during the acceleration process. This not only ensures the stability of driving, but also reduces the possible sense of loss of control during acceleration, making the driving experience smoother.

[0058] The system will only start the seat lift reminder when the vehicle speed is normal, no brake or acceleration signals are triggered, and fatigue is sensed. This multi-condition screening mechanism can accurately identify the driver's fatigue state and provide reminders at the right time to ensure the efficiency and timeliness of the reminders. The system's control logic intelligently generates control information by comprehensively analyzing the vehicle speed, brakes, acceleration and fatigue status, greatly reducing the false trigger rate. This screening mechanism reduces the probability of system false alarms or excessive reminders, making the driver's experience more friendly and reliable.

[0059] like Figure 4 As shown, step S2 includes:

[0060] S21. Generate a fatigue level according to the fatigue state. The fatigue level classification standard corresponds to relevant regulations, and levels 1 to 5 correspond to no fatigue, mild fatigue, moderate fatigue, severe fatigue and extreme fatigue. The system first generates a fatigue level according to the perceived fatigue state of the driver. The fatigue level is usually divided into multiple levels, such as low, medium, and high, so that the system can more accurately judge the driver's fatigue level and provide a basis for subsequent control.

[0061] S22. Determine the target height and lifting speed of the main driver's seat according to the fatigue level. When the fatigue level is high, the system will set a higher target height and a faster lifting speed to increase the reminder effect and ensure that the driver stays awake. When the fatigue level is low, the system can set a lower target height and a slower lifting speed to provide a gentle reminder to avoid excessive interference. The system adjusts the ventilation volume of the air valve 35 according to the fatigue level, thereby controlling the target height of the seat. When the fatigue level increases, the ventilation volume of the air valve 35 will also increase accordingly, causing the seat height to gradually rise to provide a more significant reminder effect.

[0062] The opening of the air valve 35 directly determines the lifting speed of the seat, and the speed control of different fatigue levels is achieved through the following divisions:

[0063] Minimum fatigue level: the air valve 35 is opened to 0%, the seat height remains unchanged, and the lifting speed is 0.

[0064] Fatigue level 1: The air valve 35 is open to 20%, providing a slight reminder.

[0065] Fatigue level 2: The air valve 35 is open to 40%, the seat lifting speed is medium, and the reminder force is moderate.

[0066] Fatigue level 3: The opening of valve 35 is 60%, the seat lifting speed is increased, and the reminder is strengthened.

[0067] Fatigue level 4: The air valve 35 is opened to 80%, the seat rises and falls at a faster speed, and the reminder effect is the strongest.

[0068] The system determines the ventilation volume and opening of the air valve 35 by the obtained fatigue level, and then controls the height and lifting speed of the seat, and outputs it as control information. In this way, the system can realize adaptive reminders based on fatigue status to ensure the appropriateness and effectiveness of the reminders.

[0069] S23, using the target height and the lifting speed as the control information. When the driver's fatigue level is detected to be the lowest (for example, just starting to drive or being very awake), the system will keep the seat height unchanged and the lifting speed to 0, that is, no lifting action will be performed to avoid disturbing the driver when it is not necessary. The system effectively avoids interference with low fatigue states through graded fatigue detection and adaptive height adjustment, while ensuring enhanced reminder effects when fatigue increases, providing precise support.

[0070] S3. Control the lifting device 30 to lift the main driver's seat according to the control information. The control information consists of the air volume and opening of the air valve 35, which is used to indicate the target height and lifting speed of the main driver's seat. By accurately controlling the air valve 35, the system can set the appropriate seat height and lifting speed according to the driver's current fatigue state. After the control information is transmitted to the lifting device 30, the device will adjust the main driver's seat according to the setting of the air valve 35, and raise the seat to the target height by controlling the air volume of the air valve 35 to ensure appropriate reminders when fatigued. The opening of the air valve 35 determines the speed of the seat lifting and lowering. When the fatigue state is higher, the speed is faster to enhance the reminder effect; when the state is better, the speed is slower to avoid interference.

[0071] The present invention also provides a vehicle, comprising the fatigue driving reminder system as described above.

[0072] In summary, the present invention proposes a fatigue driving reminder system, method and vehicle. In the above scheme, fatigue driving reminder is performed by seat lifting. The seat lifting reminder belongs to physical stimulation and is more accurate than simple sound and light alarm. Through precise seat fine-tuning, the driver can be reminded when he is really in a fatigued state, thereby effectively reducing false alarms, reducing the driver's boredom caused by frequent false alarms, and improving the willingness to use the DMS system. Thereby improving the safety of long-term driving. The seat lifting reminder method of the present invention only acts on the main driver's seat, and will not cause sound and light interference to other people in the vehicle, especially the co-driver who is resting, ensuring that they have enough rest and avoiding the traditional sound and light reminder affecting the rest effect of rotating driving. Compared with the sound and light alarm, which is easy to cause confusion due to multiple reminders in turn, the seat lifting method in the present invention is only effective for the main driver who actually operates. This physical reminder has clarity, which can avoid false reminders and fatigue drivers ignoring the reminder, thereby effectively improving the reliability of the reminder and driving safety. The seat lifting device 30 can flexibly adjust the lifting amplitude according to the fatigue state of the driver. It can be adjusted slightly when the driver is slightly fatigued, and it can be adjusted more sharply when the driver is seriously fatigued, so that the driver can personally feel the different degrees of fatigue reminders, forming a personalized physical stimulation, which helps to improve the reminder effect. Compared with the sound and light alarm, the seat lift reminder is more concealed and gentle, and will not bring harsh noise or sudden light stimulation, reducing the driver's psychological resistance. In long-term use, the driver will not turn off the system due to frequent false alarms, thereby maintaining a high utilization rate of the DMS system. While reminding the driver, the seat lift can also temporarily adjust the driver's sitting posture to help relieve physical fatigue and improve comfort. This functional design that combines reminders and comfort can better meet the needs of long-distance driving and improve the driver's experience.
