[0002] Fatigue driving is a major contributing factor to traffic accidents. When drivers engage in prolonged driving, especially on highways, the lower complexity of road conditions, higher speeds, and increased driver concentration make them more susceptible to fatigue.

[0003] Currently, the main solution to address driver fatigue is to use images collected by a Driver Status Monitor (DSM) system to recognize facial expressions and determine if the driver is fatigued. However, DSM systems require high-definition cameras and a main unit for driver fatigue warning, making them expensive and difficult to implement widely. In other words, the current solutions to driver fatigue are too costly. Summary of the Invention

[0065] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0066] 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, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0067] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0068] The terms "first" and "second," etc., used in the specification and claims of this application are used to distinguish different objects, not to describe a specific order of objects. For example, "first target object" and "second target object," etc., are used to distinguish different target objects, not to describe a specific order of target objects.

[0069] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0070] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0071] The vehicle control method of this application will be described below with reference to some existing technologies:

[0072] Fatigue driving is a major contributing factor to traffic accidents. When drivers engage in prolonged driving, especially on highways, the lower complexity of road conditions, higher speeds, and increased driver concentration make them more susceptible to fatigue.

[0073] Currently, the main solution to address driver fatigue is to use images captured by a Driver Status Monitor (DSM) system to recognize facial expressions and determine if the driver is fatigued. However, DSM systems require high-definition cameras and a main unit for driver fatigue warning, making them expensive and difficult to implement widely. In other words, the current solutions to driver fatigue are too costly.

[0074] Furthermore, current methods for detecting driving duration typically involve monitoring the engine's start-stop cycle to determine if driving time is excessive. While this method is cost-effective, using engine start-stop as a measure of driving duration has relatively low accuracy in identifying fatigued driving.

[0075] This application determines the continuous driving period of the current journey by using the vehicle's speed information during the current trip. Based on this continuous driving period, the current fatigue driving duration can be calculated. Then, based on the fatigue driving duration, an appropriate fatigue driving reminder can be given to the driver. This effectively reduces the cost of fatigue driving detection, and compared to using engine start-stop intervals as the driving duration, this application has higher accuracy in determining fatigue driving.

[0076] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the vehicle control method of this application. It should be noted that although the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown here.

[0077] The first embodiment of this application provides a vehicle control method, which includes the following steps:

[0078] Step S100: Obtain the vehicle speed information during the current journey;

[0079] In this embodiment, it should be noted that the current trip refers to the current travel distance of the vehicle. It is understood that the vehicle's journey from the start time to the next stop time can be considered as one trip, or the vehicle's journey from the start time to the next stop time where the parking time exceeds a preset time threshold (e.g., 5 minutes, 10 minutes, etc.) can be considered as one trip. For example, the current trip can be the vehicle's journey from the start time to the current time, and the parking time during the journey does not exceed the preset time threshold. The vehicle speed information includes at least the real-time vehicle speed corresponding to each travel moment in the current trip.

[0080] Since both traditional gasoline-powered vehicles and electric or hybrid new energy vehicles use instrument clusters, the power generated by either the engine or the electric motor, converted into vehicle speed, is displayed on the instrument cluster directly in front of the driver. In this embodiment, the vehicle's instrument cluster can monitor real-time speed and travel time, thereby obtaining the vehicle's speed information during the current journey.

[0081] Step S200: Based on the vehicle speed information, identify the continuous driving period of the current trip;

[0082] In this embodiment, it is understood that the vehicle may experience traffic jams and temporary stops during operation, especially on highways where traffic jams may last for half an hour or even more than an hour, with slow-moving traffic or complete gridlock. Since the vehicle speed is usually slow in traffic jams, it does not require the user to concentrate highly, and the need to follow other vehicles and brake from time to time also makes it less likely for the user to be distracted. Therefore, it is less likely to cause user fatigue in slow-moving conditions.

[0083] As an example, the real-time vehicle speed in the vehicle speed information can be filtered based on a preset vehicle speed threshold (such as 5km / h, 10km / h, 15km / h, etc.), and the time period that is higher than the preset vehicle speed threshold can be used as the continuous driving period of the current trip.

[0084] The step S200, which involves identifying the continuous driving period of the current trip based on the vehicle speed information, includes:

[0085] Step S210: Generate the real-time vehicle speed sequence of the current trip based on the vehicle speed information;

[0086] Step S220: The time period in the real-time vehicle speed sequence that is higher than the preset vehicle speed threshold is taken as the continuous driving period of the current trip.

[0087] In this embodiment, it should be noted that the vehicle speed information includes at least the real-time vehicle speed corresponding to each travel moment during the current journey.

[0088] In this embodiment, the real-time vehicle speeds can be sorted according to the time sequence of the travel times to obtain the real-time vehicle speed sequence of the current trip. Then, the time periods in the real-time vehicle speed sequence that are higher than a preset speed threshold can be taken as the continuous driving period of the current trip. It is understood that the current trip includes at least one continuous driving period. Furthermore, to reduce interference, each continuous driving period can be filtered to obtain new continuous driving periods. For example, continuous driving periods shorter than a preset duration (e.g., 30 seconds, 1 minute, 2 minutes, etc.) can be deleted to obtain new continuous driving periods. Therefore, this embodiment can more accurately identify the continuous driving periods in the current trip that may affect the user's fatigue level.

[0089] Step S300: Calculate the current fatigue driving duration based on the continuous driving period;

[0090] As an example, in this embodiment, the current fatigue driving time of the driver can be calculated by accumulating the duration of the continuous driving periods. As another example, since the impact of different driving states on user fatigue levels varies, the vehicle speed fluctuation value corresponding to each continuous driving period can be calculated based on the vehicle speed information. The vehicle speed fluctuation value is a quantity characterizing the change in vehicle speed, and can be a quantity such as the standard deviation, range, or variance of the vehicle speed. Then, based on the vehicle speed fluctuation value, the fatigue weight of the continuous driving period is determined. Based on the continuous driving period and the corresponding fatigue weight, the current fatigue driving time is calculated. Therefore, the continuous driving periods can be weighted according to different driving states, and the current fatigue driving time calculated in this way is more representative of the user's fatigue level than simply accumulating the time.

[0091] Step S400: Based on the fatigue driving duration, issue a corresponding fatigue driving reminder.

[0092] In this embodiment, based on the current fatigue driving duration, the driver's actual fatigue driving state can be determined, and a preset fatigue reminder operation can be executed to remind the driver of corresponding fatigue driving. The preset fatigue reminder operation can include at least one of: optical reminder operation, acoustic reminder operation, and vibration reminder operation. For example, the optical reminder operation can remind the driver through text, images, or symbols, such as displaying the text "Please note, you have driven for XX hours, please take a rest" on a screen. The acoustic reminder operation can remind the driver through music, voice, or warning sound effects, such as playing the voice message "Please note, you have driven for XX hours, please take a rest" through the in-vehicle speaker. The vibration reminder operation includes seat vibration, steering wheel vibration, etc., to remind the driver. For example, the driver's seat can be vibrated to remind the driver.

[0093] As an example, a fatigue driving threshold, such as 2 hours, 3 hours, or 4 hours, can be preset. Once the fatigue driving duration exceeds this threshold, a preset fatigue reminder can be executed to alert the driver. As another example, since different times of day affect driver fatigue levels differently—for example, drivers are often more prone to fatigue late at night, early morning, or at noon—corresponding fatigue driving thresholds can be preset for different time periods. The appropriate fatigue driving threshold can then be selected based on the current time period. Once the fatigue driving duration exceeds this threshold, a preset fatigue reminder is executed to alert the driver.

[0094] In the first embodiment of this application, vehicle speed information during the current journey is obtained. Since the driver is not continuously driving during a journey, the continuous driving period of the current journey can be identified based on the vehicle speed information. Then, the current fatigue driving duration is calculated based on the continuous driving duration. Finally, based on the fatigue driving duration, a suitable method is used to provide corresponding fatigue driving reminders to the driver. Therefore, this application can detect and remind drivers of fatigue driving behavior without using an expensive DSM system, effectively reducing the cost of fatigue driving detection.

[0095] Reference Figure 2 , Figure 2 This is a flowchart illustrating the second embodiment of the vehicle control method of this application.

[0096] The second embodiment of this application provides a vehicle control method, wherein step 300, which involves calculating the current fatigue driving duration based on the continuous driving period, includes:

[0097] Step S310: Calculate the vehicle speed fluctuation value corresponding to each of the continuous driving periods based on the vehicle speed information.

[0098] Step S320: Determine the fatigue weight of the continuous driving period based on the vehicle speed fluctuation value;

[0099] Step S330: Calculate the current fatigue driving duration based on the continuous driving period and the corresponding fatigue weight.

[0100] In this embodiment, it should be noted that the vehicle speed fluctuation value is a quantity characterizing the change in vehicle speed. This value can be the standard deviation, range, variance, or other values ​​of the vehicle speed. Taking the standard deviation of vehicle speed as an example, a larger standard deviation indicates greater speed fluctuation and a larger change in vehicle speed. A large change in vehicle speed indicates that the driver is not driving for an extended period under road conditions with low complexity. It is understandable that when drivers are in long-term, simple road conditions, their speed is usually more stable, which can lead to driver fatigue.

[0101] In this embodiment, based on the vehicle speed information, the vehicle speed fluctuation value corresponding to each of the continuous driving periods can be calculated. Then, based on the vehicle speed fluctuation value and a preset correspondence, the fatigue weight of each continuous driving period can be determined. It is understood that the preset correspondence is the relationship between the vehicle speed fluctuation value and the fatigue weight, which can be expressed by formulas, mapping tables, curve functions, etc. For example, the vehicle speed fluctuation value and the fatigue weight are negatively correlated. That is, the larger the vehicle speed fluctuation value, the greater the speed change, the less likely the driver is to experience fatigue, and the lower the fatigue weight. Therefore, the current fatigue driving duration can be obtained by weighting each of the continuous driving periods based on the fatigue weight. For example, the durations corresponding to each continuous driving period are 0.3 hours, 0.8 hours, and 0.2 hours, respectively, and the corresponding fatigue weights are 0.8, 1.5, and 0.8, respectively. Then the current fatigue driving duration is 0.3*0.8 + 0.8*1.5 + 0.2*0.8 = 1.6. That is, the current fatigue driving duration is the sum of the product of the duration of continuous driving and the corresponding fatigue weight.

[0102] The step S320, which involves determining the fatigue weight of the continuous driving period based on the vehicle speed fluctuation value, includes:

[0103] Step S321: Divide the continuous driving period into sub-periods according to a preset duration to obtain each driving sub-period.

[0104] Step S322: Based on the vehicle speed fluctuation value of each driving sub-period, query a preset mapping table to obtain the fatigue weight of each driving sub-period as the fatigue weight of the continuous driving period.

[0105] Because driving states can change over a continuous driving period, this embodiment divides the continuous driving period into sub-periods according to preset durations (e.g., 10 minutes, 15 minutes, 20 minutes, etc.) to further improve the accuracy of current fatigue driving duration in representing user fatigue levels. Then, based on the vehicle speed fluctuation value of each sub-period, a preset mapping table is consulted to obtain the fatigue weight of each sub-period, which serves as the fatigue weight for the continuous driving period. The preset mapping table includes the correspondence between vehicle speed fluctuation values ​​and fatigue weights. Therefore, the current fatigue driving duration can be calculated based on the duration of each sub-period and its corresponding fatigue weight.

[0106] In the second embodiment of this application, the vehicle speed fluctuation value corresponding to each continuous driving period is calculated based on the vehicle speed information, thereby determining the vehicle's driving state based on the speed changes. Since different driving states have different impacts on user fatigue, the fatigue weight of each continuous driving period can be determined based on the vehicle speed fluctuation value. The current fatigue driving duration is calculated based on the continuous driving period and its corresponding fatigue weight. The calculated current fatigue driving duration is more representative of the user's fatigue level than simple cumulative timing. Therefore, this embodiment further improves the accuracy of fatigue detection without increasing hardware costs.

[0107] Reference Figure 3 , Figure 3 This is a flowchart illustrating the third embodiment of the vehicle control method of this application.

[0108] The third embodiment of this application provides a vehicle control method, wherein step S400, which involves providing a corresponding fatigue driving reminder based on the fatigue driving duration, includes:

[0109] Step S410: Obtain the current time period of the current trip and determine the fatigue driving threshold corresponding to the current time period;

[0110] Step S420: After the fatigue driving duration exceeds the fatigue driving threshold, a first preset prompt message is output to the driver to remind him of fatigue driving.

[0111] In this embodiment, the current time period refers to the time period within the current day of the vehicle, such as early morning, morning, noon, afternoon, evening, and late night. The time endpoints of each time period can be set according to specific needs.

[0112] As an example, the current time period of the current trip can be obtained, and the fatigue driving threshold corresponding to the current time period can be determined based on the correspondence between different time periods within a day and a preset fatigue driving threshold. Then, if the fatigue driving duration exceeds the fatigue driving threshold, it indicates that the driver is in a fatigued driving state, and a first preset prompt message is output to the driver to remind them of fatigue driving. The first preset prompt message can be output in the form of text, images, symbols, sound, vibration, etc.

[0113] In this embodiment, considering the varying impact of different time periods within a day on driver fatigue levels, a corresponding fatigue driving threshold is selected based on the current time period of the current journey. Then, the driver's state of fatigue is determined based on this fatigue driving threshold. This improves the accuracy of fatigue detection.

[0114] The step following step S420, which involves outputting a first preset prompt to the driver to remind them of driver fatigue, includes:

[0115] Step S430: After not receiving feedback from the driver regarding the first preset prompt message, send a second preset prompt message to a preset designated contact person;

[0116] Step S431: Receive feedback reminder information from the preset designated contact regarding the second preset prompt information, and output the feedback reminder information to the driver to provide fatigue driving reminder.

[0117] In this embodiment, it should be noted that the preset designated contact person can be a relative, friend, leader, or other person of the driver.

[0118] In this embodiment, if no feedback operation from the driver regarding the first preset prompt information is received within a preset feedback time period (e.g., 3 minutes, 5 minutes, 10 minutes), a second preset prompt information is sent to a preset designated contact. The feedback operation may include actions indicating the validity of the first preset prompt information, such as slowing down, navigating to a parking area, or pulling over. If no feedback operation from the driver regarding the first preset prompt information is received within the preset time period, it indicates that the first preset prompt information is ineffective for the driver. In this case, a second preset prompt information can be sent to the communication device of the preset designated contact. The second preset prompt information may include fatigue driving information such as the driver's current fatigue duration and current location, used to alert the preset designated contact that the driver is driving while fatigued. The system receives feedback from the preset designated contact regarding the second preset prompt information and outputs this feedback reminder to the driver to provide a fatigue driving warning. The feedback reminder information may be text, voice, call requests, etc., from the preset designated contact. This outputs feedback reminder information from a preset designated contact with a close relationship to the driver to provide a fatigue driving warning. This is more easily accepted by the driver than vehicle-preset prompt information.

[0119] This embodiment improves the effectiveness of intervention against fatigued driving by reminding the driver through a pre-designated contact person with a close relationship with the driver after the first preset prompt message is ineffective, thereby enhancing the safety of the driver when fatigued driving occurs.

[0120] The step S420, which involves outputting a first preset prompt to the driver to remind them of driver fatigue, further includes:

[0121] Step S440: After not receiving feedback from the driver regarding the first preset prompt information, output a fatigue relief request;

[0122] Step S441: After the driver does not accept the fatigue relief request, control the vehicle to slow down.

[0123] In this embodiment, it should be noted that the fatigue relief request is a request to perform an operation to relieve user fatigue, which includes operations such as playing upbeat music with an energizing effect and releasing fragrance with an energizing effect.

[0124] In this embodiment, if no feedback operation from the driver regarding the first preset prompt information is received within a preset feedback time, a fatigue relief request is output. If the driver does not accept the fatigue relief request, it indicates that the driver refuses to accept intervention to alleviate fatigue. To ensure the driver's safety, the vehicle can be controlled to reduce speed. For example, the vehicle's VCU (Vehicle Control Unit) limits the drive torque of the powertrain, restricting the vehicle's output torque. Then, the Electronic Brake System (EBS) forces a speed reduction, while the Anti-lock Braking System (ABS) and Electronic Stability Controller (ESC) ensure vehicle stability and driving safety.

[0125] In this embodiment, after the driver refuses to accept interventions to alleviate fatigue, the vehicle is forcibly slowed down, thereby further reducing the driving risk of the driver being in a fatigued driving state.

[0126] Furthermore, it is understood that the embodiments of steps S430 and S433 and the embodiments of steps S440 and S441 may only be executed, or may be executed simultaneously or sequentially. This application does not impose any restrictions in this regard.
