Description

Technical Field

[0001] The present invention belongs to the field of intelligent driving technology, and specifically relates to a vehicle control system, method and medium oriented to driving status. Background Art

[0002] With the continuous growth of car ownership and the increasing complexity of the road traffic environment, driver fatigue driving has become one of the important factors causing traffic accidents. Traditional fatigue monitoring and assisted driving technologies have some defects in driving safety. Although the traditional fatigue monitoring system can detect the driver's fatigue state, due to the lack of vehicle-cloud collaboration, it cannot effectively solve the problem of high computing power cost of the current system, and it also lacks the function of remote safety intervention in emergency situations. This makes it difficult for the system to achieve efficient fatigue monitoring and timely safety intervention in actual applications, limiting its practicality in actual driving scenarios.

[0003] Traditional assisted driving systems are usually equipped with function switches, and drivers can manually turn on or off related functions. However, when the driver is in a state of fatigue, he may mistakenly turn off the assisted driving function due to reduced judgment, resulting in the system being unable to provide the necessary vehicle control function at critical moments, increasing driving risks. At the same time, these systems can often only trigger warnings and intervention measures when the vehicle deviates from the lane or is about to cross the line. They cannot actively respond to the driver's fatigue state, lack timely and effective reminders and early intervention measures for the driver, and it is difficult to fundamentally ensure driving safety.

[0004] In addition, traditional assisted driving systems usually use a single warning method (such as sound or vibration) and are only triggered under specific conditions. They cannot provide continuous and effective reminders based on the driver's fatigue level, making it difficult to ensure that the driver always remains alert. They cannot dynamically adjust the warning strategy based on the driver's status, making it difficult to achieve accurate warnings and effective intervention. In addition, existing technologies often fail to fully utilize the existing automotive architecture to solve the above problems, resulting in complex system design, increased vehicle manufacturing costs and vehicle complexity. Many solutions require additional hardware equipment or large-scale vehicle modifications, which not only increases the vehicle manufacturing cost, but may also affect the vehicle's original performance and reliability.

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0026] It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments of the present application. In addition, in the following embodiments, the description of each embodiment has its own emphasis, and for parts not described in detail in one embodiment, reference can be made to the relevant description of other embodiments.

[0027] Fatigue driving is a common traffic safety hazard that significantly increases the risk of road accidents. Long-term continuous driving, lack of adequate rest and sleep, and other physical and psychological factors may cause drivers to enter a fatigued state. In a fatigued state, the driver's reaction ability, judgment and attention will be significantly reduced, which will affect his ability to control the vehicle and threaten driving safety.

[0028] like Figure 1-3 As shown, the first aspect of the present invention provides a vehicle control system oriented to a driving state, comprising: Perception system, central controller and execution controller.

[0029] Specifically, the perception system at least includes a fatigue monitoring system; the central controller is also called the central brain controller or intelligent driving controller, which is the main logic integration part of the current automobile intelligent driving system. The upstream can receive information input from the perception system, and at the same time has high security and high computing power, and has the ability to control the downstream execution controller; please continue to refer to Figure 2 The execution controller is also called an actuator, which includes at least one or more of a vehicle cabin controller, a steering wheel and seat belt controller, a vehicle steering controller, and a vehicle braking system controller, or the execution controller is at least used to meet one or more of a vehicle lateral control function, a vehicle longitudinal control function, and a vehicle early warning reminder function.

[0030] Specifically, the fatigue monitoring system is at least used to obtain and analyze the driver's fatigue status, and the driver's fatigue status at least includes a fatigue level, wherein the perception system is used to assist the central controller in performing analysis and processing. In addition to the fatigue monitoring system, other additional perception data may also be added through the perception system.

[0031] Specifically, the perception system at least includes a fatigue monitoring system, which is at least used to obtain and analyze the driver's fatigue state through a preset monitoring method, and the driver's fatigue state at least includes a fatigue level. The fatigue monitoring system and the preset monitoring method it contains can be implemented through existing technologies, that is, they can be implemented through a variety of sensors or data sources, such as cameras, infrared sensors, steering wheel grip sensors, heart rate monitoring equipment, etc., for collecting the driver's facial features, eye activities, head posture, physiological signals, and driving behavior data. Based on these data, the system analyzes the driver's fatigue state through a preset algorithm model (such as a machine learning model or a deep learning model) and outputs the corresponding fatigue level. The perception system is used to assist the central controller in realizing analysis and processing, and fuses and analyzes the data obtained by the fatigue monitoring system with other vehicle operation data (such as vehicle speed, acceleration, steering angle, etc.) to further improve the accuracy and reliability of fatigue state judgment.

[0032] In addition to the fatigue monitoring system, the perception system can also expand other additional perception data to enhance the system's comprehensive judgment ability. For example, the environmental information around the vehicle, including lane line position, distance to the vehicle in front, pedestrians or obstacles, etc., can be obtained through the on-board camera or radar sensor; the vehicle's posture and motion state data can be obtained through the on-board inertial measurement unit (IMU); and real-time traffic information or weather conditions can be obtained through the on-board communication module. These additional perception data can be combined with the data from the fatigue monitoring system to provide a more comprehensive decision-making basis for the central controller. In addition, the scalability of the perception system also supports the upgrade and optimization of future functions, such as by adding new sensors or algorithm modules to further enhance the system's intelligence level and adaptability.

[0033] In the present invention, the existing fatigue monitoring system can be used to monitor the driver's fatigue state, for example, by analyzing the driver's facial expressions, eye activities or physiological signals to determine the driver's fatigue level. Among the existing fatigue monitoring systems, the visual fatigue monitoring system is the most widely used, which determines the driver's fatigue level through image recognition of the number of frames of the driver's closed eyes within the time window, yawning movements, and the time when the driver's line of sight leaves the front windshield area. In addition, in the existing fatigue monitoring system, there are also biosensors that monitor the driver's physiological parameters, such as heart rate, blood pressure, and skin resistance, to determine the driver's fatigue level.

[0034] Exemplarily, the fatigue monitoring system divides the fatigue level into mild fatigue, moderate fatigue and severe fatigue according to the severity of the fatigue level, or further refines the division according to the severity of the actual fatigue level, such as the first fatigue level, the second fatigue level, the third fatigue level, the fourth fatigue level and the fifth fatigue level with increasing fatigue severity, which still fall within the scope of protection of the present invention.

[0035] The central controller obtains and analyzes the driver's fatigue status from the perception system; the central controller adjusts the warning signal sensitivity of the preset vehicle driving function based on the fatigue status obtained by the analysis and triggers the driver's warning prompt, and selectively controls the vehicle action and provides continuous warning prompts to the driver through the execution controller.

[0036] Specifically, the preset vehicle driving functions include at least a lane keeping function and an assisted driving function; the central controller adjusts the warning signal sensitivity level of the lane keeping function and the assisted driving function according to the fatigue state, and provides the driver with a driver warning prompt and monitors the driver's reaction status through the warning reminder switch configured in the central controller; the warning signal includes at least a lane departure signal and a collision signal, and the driver's reaction status includes at least a normal driver reaction state, an abnormal driver reaction state and a no driver reaction state.

[0037] When the central controller monitors that the driver's reaction state is an unresponsive state or an abnormal driver reaction state, the execution controller controls the vehicle to keep driving in a preset lane and maintain a safe distance from the vehicle in front, and controls the execution controller to provide continuous warning prompts to the driver.

[0038] Specifically, the central controller adjusts the sensitivity of the warning signal to the highest sensitivity according to the fatigue level, wherein the driver's fatigue level is divided into three types, including mild fatigue, moderate fatigue and severe fatigue, representing the driver's state. For example, the sensitivity of the intelligent driving assistance function is divided into three types, including low, medium and high sensitivities, and the TTC of the functions triggered by different sensitivities is different. When the non-fatigue state of driving is detected, the sensitivity of the function triggering is selected by the driver according to the driving habits. When the driver is detected to be in a fatigue state including mild, moderate and severe fatigue, the system will automatically adjust the sensitivity of the auxiliary system to the highest to ensure the safety of the driver. Even in the current driving cycle, the driver's fatigue level is lifted, and the system will maintain the sensitivity of the intelligent driving assistance function at the highest sensitivity. In view of the usual biological characteristics of the driver, fatigue will not disappear in a short time. Through fatigue level detection and dynamic adjustment of TTC, the sensitivity optimization of the intelligent driving assistance system is realized to ensure that the most appropriate safety protection can be provided under different driving conditions, especially when the driver is fatigued, the system will operate at the highest sensitivity to minimize the risk of accidents.

[0039] Specifically, if the current warning signal switch is in the off state, the warning reminder switch will be turned on. When the monitoring alarm signal of the driver's unresponsive state and the driver's abnormal response state is received, the lane keeping assisted driving and collision assisted driving functions will be turned on, and the vehicle's lateral movement will be adjusted to keep the vehicle driving in the set lane and maintain a safe distance from the involved vehicle to prevent the vehicle from rear-ending.

[0040] In addition, the present invention is also configured with an execution activation module, which can activate the lane keeping function and the vehicle braking function of the vehicle.

[0041] For example, when the lane keeping function of the current vehicle is off but the vehicle needs to be controlled by the lane keeping function, the system will force the lane keeping function to be turned on, and ensure that the vehicle is driving in the lane and does not rear-end the vehicle in front by adjusting the steering wheel or applying a slight braking force. This comprehensive fatigue monitoring and lane control system enables the driver to be aware of his or her fatigue state in time, and ensures the safety and stability of driving through active control measures, effectively making up for the defects of existing technologies, providing comprehensive driver fatigue monitoring and vehicle keeping control functions, and improving driving safety.

[0042] Here, through this method, the disadvantages of the existing technology that the vehicle lacks the corresponding active reminder and control mechanism, cannot take effective intervention measures in time after monitoring the driver's fatigue state, and is difficult to correct the driver's unsafe behavior can be improved. The present invention can give full play to the safety protection of vehicles and users in practical applications, and ensure driving safety from the perspectives of driver reminders, lateral control of the car and longitudinal control of the car, avoiding traffic accidents caused by the driver's lack of concentration or slow reaction due to fatigue. In addition, in order to ensure that the driver can realize his abnormal state in time and take corresponding measures, the present invention reminds the driver through high-frequency early warning prompts, including but not limited to sound prompts, pop-up warnings on the central control screen, seat vibrations, etc. This multi-level reminder mechanism can effectively improve the driver's alertness and avoid safety hazards caused by fatigue or distraction.

[0043] Please continue reading Figure 3 In one embodiment of the present invention, the driving state-oriented vehicle control system also includes a cloud and a control signal terminal.

[0044] The cloud is at least used to collect historical data of the central controller's warning prompts to the driver and continuous warning prompts to the driver, and to assist the central controller in analyzing the driver's fatigue status, as well as to update and diagnose the perception system, the central controller and the execution controller.

[0045] The control signal in the control signal terminal includes at least an Ethernet signal, a CAN signal or a LIN signal, and the control signal is at least used to obtain the driver's fatigue state through the control signal and respond to the control instruction issued by the central controller to the execution controller.

[0046] Specifically, the present invention has a vehicle-cloud integration function, and through the introduction of a cloud server, the intelligence level and scalability of the system are further improved.

[0047] Specifically, the cloud can not only realize remote upgrades and iterations of control logic, but also collect historical alarm data from the vehicle side, and combine big data analysis and machine learning algorithms to conduct in-depth analysis of the driver's fatigue status, driving behavior and vehicle operation status. This data analysis capability enables the system to more accurately identify the driver's abnormal status and respond to emergencies in a timely manner, thereby significantly improving the safety of the vehicle. For example, when the system detects that a driver frequently has fatigue warnings within a specific time period, it can actively suggest that the driver take a rest or adjust the driving plan to avoid potential safety risks.

[0048] In addition, the cloud also supports remote updates and diagnostics for domain controller software. Through the cloud, software updates for vehicle assisted driving systems, fatigue monitoring systems, and other key control modules can be achieved to ensure that the system always has the latest functions and optimal performance. At the same time, the cloud diagnostic function can monitor the operating status of the system in real time, and promptly discover and repair system failures and security vulnerabilities, thereby ensuring the reliability and stability of the monitoring system itself and avoiding misjudgments or failures caused by system failures.

[0049] The cloud data statistics and development functions further expand the application scenarios and capabilities of the system. Through real-time monitoring of vehicle performance data, the system can evaluate the health status of the vehicle and provide maintenance recommendations; through analysis of driving behavior, the system can provide drivers with personalized driving recommendations to help them improve their driving habits; through the safety monitoring and early warning function, the system can issue early warnings when potential dangers are detected to reduce the probability of accidents; through software updates and remote diagnosis functions, the system can continuously optimize the user experience and ensure that the vehicle is always in the best operating state. The realization of these functions provides strong support and expansion capabilities for the operation and management of smart cars, which not only improves the safety and reliability of vehicles, but also lays a technical foundation for the development of future intelligent transportation systems.

[0050] Preferably, the present invention uses low-cost and high-reliability CAN signals for interaction. The CAN bus protocol has high real-time performance, can achieve fast data transmission and response, and meet the requirements of vehicle control systems for low latency and high reliability. At the same time, the CAN bus supports multi-node connections and can simultaneously connect a large number of sensors, actuators, and control units, thereby achieving interconnection and interoperability of complex systems, which not only simplifies the architecture of the vehicle electronic system, but also improves the flexibility and scalability of the system.

[0051] like Figure 4 As shown, the second aspect of the present invention provides a vehicle control method oriented to a driving state, comprising: Step S100: Acquire and analyze the driver's fatigue state; Step S200: Based on the fatigue state obtained by analysis, the warning signal sensitivity of the preset vehicle driving function is adjusted to trigger a driver warning prompt, and the vehicle action and continuous warning prompt are selectively controlled.

[0052] In one embodiment of the present invention, the step of obtaining and analyzing the driver's fatigue state includes: Whether the driver is driving fatigued is determined by a preset monitoring method and the corresponding driver's fatigue state is obtained, wherein the driver's fatigue state at least includes a fatigue level.

[0053] like Figure 5 As shown, in one embodiment of the present invention, the sensitivity of the warning signal of the preset vehicle driving function is adjusted based on the fatigue state obtained by analysis and the driver is triggered to be warned, and the vehicle action is selectively controlled and the driver is continuously warned, including: Step S210: adjusting the warning signal sensitivity level of the lane keeping function and the auxiliary driving function of the vehicle according to the fatigue state, and providing a driver warning prompt to the driver and monitoring the driver's reaction state; Step S220: When the driver's reaction state is monitored to be an unresponsive state or an abnormal driver reaction state, the vehicle is controlled to maintain driving in a preset lane and maintain a safe distance from the vehicle in front, and continuous warning prompts are given to the driver.

[0054] Specifically, based on the actual structure of the vehicle, in the present invention, its main controlled and interactive objects include the vehicle cockpit controller, steering wheel and seat belt controller, vehicle steering controller, vehicle braking system controller, etc. After the central controller issues the corresponding control command, the cockpit screen pops up and issues an alarm tone, and the steering wheel and seat belt vibrate and tighten respectively. After the vehicle's lane keeping function is activated, when the vehicle is about to reach the critical value of the line, lateral control is required to keep the vehicle in the lane. When the distance between the vehicle and the vehicle in front is too close or the vehicle in front brakes, the braking system of this vehicle needs to brake.

[0055] Specifically, the present invention needs to ensure that the actuator can respond normally and quickly to the control instructions or control signals issued by the central control brain. The control instructions or control signals can be interactively transmitted through Ethernet signals, CAN signals or LIN signals.

[0056] Furthermore, the method needs to be able to accurately identify the driver's fatigue state. Usually, this involves using a camera or other sensors to monitor the driver's eye activity, head posture, hand movements and other indicators, and using algorithm analysis to determine whether the driver is in a fatigue state.

[0057] Furthermore, the method needs to be able to issue reminders and warnings in time according to the driver's fatigue status to attract the driver's attention and prompt him to take corresponding actions. This may involve reminder and warning technologies in various ways such as sound, vibration, and light, as well as corresponding user interface design and human-computer interaction technology.

[0058] Furthermore, this method requires the technology to control the vehicle laterally and longitudinally, which involves technologies such as vehicle stability control, lane keeping system, adaptive cruise control, etc., to ensure that the vehicle can still maintain a safe driving trajectory under fatigue driving conditions.

[0059] Furthermore, this method requires V2X communication technology to transmit the vehicle's internal data to the cloud in real time, and to transmit the cloud control instructions to the vehicle in a timely manner. This may involve deploying machine learning and deep learning algorithms in the cloud, as well as trajectory planning algorithms, to ensure that the vehicle can safely pull over and call for help in a timely manner when the driver is detected to be unresponsive.

[0060] like Figure 6 As shown, the third aspect of the present invention provides an electronic device, comprising: at least one processor; and at least one memory communicatively connected to the processor, wherein: the memory stores program instructions executable by the processor, and the processor calls the program instructions to execute the steps of the method described in any one of the above embodiments.

[0061] A fourth aspect of the present invention discloses a readable storage medium storing a computer program, wherein the computer program is executed by a processor to perform the steps of the method described in any one of the above embodiments.

[0062] Computer-readable storage media may include: any entity or device capable of carrying a computer program, a recording medium, a USB flash drive, a mobile hard disk, a magnetic disk, an optical disk, a computer memory, a read-only memory (ROM), a random access memory (RAM), and a software distribution medium, etc. A computer program includes a computer program code. The computer program code may be in source code form, object code form, an executable file, or some intermediate form, etc. A computer-readable storage medium may include: any entity or device capable of carrying a computer program code, a recording medium, a USB flash drive, a mobile hard disk, a magnetic disk, an optical disk, a computer memory, a read-only memory (ROM), a random access memory (RAM), and a software distribution medium, etc.

[0063] Any process or method description in a flowchart or otherwise described herein may be understood to represent a module, segment or portion of code that includes one or more executable instructions for implementing the steps of a specific logical function or process, and the scope of the preferred embodiments of the present invention includes alternative implementations in which functions may not be performed in the order shown or discussed, including performing functions in a substantially simultaneous manner or in the reverse order depending on the functions involved, which should be understood by those skilled in the art to which the embodiments of the present invention belong.

[0064] The logic and / or steps represented in the flowchart or otherwise described herein, for example, can be considered as an ordered list of executable instructions for implementing logical functions, which can be embodied in any computer-readable medium for use by an instruction execution system, apparatus or device (such as a computer-based system, a system including a processing module or other system that can fetch instructions from an instruction execution system, apparatus or device and execute instructions), or used in combination with these instruction execution systems, apparatuses or devices.
