[0037] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] With the widespread adoption of intelligent driving technology, more and more drivers are enjoying the numerous conveniences it brings. Intelligent driving technology can reduce the driver's workload to some extent, such as enabling automatic following and lane keeping on highways, allowing drivers to relax a bit during long drives. However, current intelligent driving is not the same as fully intelligent driving. Although intelligent driving technology is constantly developing and progressing, it still has certain limitations and cannot yet cope with all complex road conditions and unexpected situations. Therefore, during intelligent driving, drivers still need to remain vigilant and closely monitor the vehicle's operating status at all times.

[0040] However, some drivers, due to insufficient understanding of intelligent driving technology, rely entirely on it for convenience, resulting in dangerous behaviors such as falling asleep or taking their hands off the steering wheel. To address this issue, numerous monitoring solutions have been designed to promptly alert and warn drivers when the system detects driver inattention or improper driving actions.

[0041] However, in order to prevent the system from issuing alerts and warnings, some drivers use auxiliary devices to simulate the state of a human hand holding the steering wheel, or even obstruct the camera responsible for capturing the driver's face, thus preventing the system from recognizing the driver and preventing the system from issuing alerts and warnings. This application provides a solution to this problem.

[0042] Figure 1 This is a flowchart of a driver status monitoring method provided in an embodiment of this application. See also... Figure 1 The driver condition monitoring method specifically includes the following steps:

[0043] S110, In response to the detection of changes in the driving environment, determine the preset driving index information of the target vehicle.

[0044] Information regarding changes in the driving environment indicates that the vehicle needs to slow down. For example, a sudden increase in rainfall leading to a sudden decrease in visibility would require the vehicle to immediately slow down to ensure driving safety. Based on this, when changes in the driving environment are detected, the target vehicle's preset driving indicators (such as changes in speed) are determined. If the changes in the driving environment do not match the vehicle's preset driving indicators (e.g., a sudden decrease in visibility without a decrease in speed), it is determined that the driver's driving state is not focused enough and does not meet requirements, posing a driving safety risk. In such cases, timely reminders and warnings should be issued to encourage the driver to increase their focus and drive attentively.

[0045] Optionally, the information about changes in the driving environment can also include information that indicates the need to slow down the vehicle, such as a sudden deterioration in road surface smoothness, a sudden deterioration in road traffic flow, or the appearance of water accumulation ahead.

[0046] For example, the changes in the driving environment include one or more of the following: visibility decreases to a first preset value, rainfall increases to a second preset value, the windshield wiper speed of the target vehicle (referring to automatic windshield wipers, whose oscillation speed automatically increases with increasing rainfall) increases to a third preset value, entering a construction zone, entering a congested zone, or entering a speed-limited zone. The first, second, and third preset values ​​can be manually set based on experience.

[0047] Visibility can be determined through image recognition or by real-time communication with a meteorological platform, and rainfall data can also be obtained from the meteorological platform. Construction zones, congested zones, and speed-limited zones can be identified using high-precision maps.

[0048] The preset driving index information of the target vehicle may specifically include vehicle speed, change in vehicle speed, acceleration, and change in acceleration.

[0049] For example, the preset driving index information includes the change in vehicle speed; determining the preset driving index information of the target vehicle includes: acquiring the vehicle speed data of the target vehicle at a target time from a vehicle speed sensor or an on-board communication bus, and determining the change in vehicle speed based on the vehicle speed data.

[0050] The target time is determined based on the time at which the change in the driving environment information is detected. For example, if the time when the change in the driving environment information is detected is time t2, then time t1, which is adjacent to time t2 and preceding time t2, and time t2 are determined as the target time. The change in vehicle speed is determined based on the vehicle speed at time t2 and the vehicle speed at time t1.

[0051] Alternatively, the target time can be defined as time t1, which is adjacent to but before time t2, and time t3, which is adjacent to but after time t2. The change in vehicle speed is determined based on the vehicle speed at time t3 and the vehicle speed at time t1. The rationale for this setting is to account for the delay in driver control, thus the change in vehicle speed is also delayed, thereby improving the accuracy of driver status monitoring.

[0052] S120. Determine whether the driver's state meets the requirements based on the preset driving index information and the change information of the driving environment.

[0053] The driver's state specifically includes driving state and take-over state. When the driver is autonomously driving the vehicle, the driver's state refers to driving state; when the driver sets the vehicle to use intelligent driving mode, the driver's state refers to take-over state. Both driving state and take-over state refer to the driver's level of concentration.

[0054] In some implementations, if the preset driving indicator information does not match the change information of the driving environment, the driver's state is determined to be unsatisfactory.

[0055] Furthermore, the step of determining that the driver's driving state does not meet the requirements if the preset driving indicator information does not match the change information of the driving environment includes:

[0056] If the change in vehicle speed indicates an increase in vehicle speed, or the decrease in vehicle speed does not reach the set value, then it is determined that the preset driving indicator information does not match the change information of the driving environment, and the driver's driving state does not meet the requirements.

[0057] For example, if the driving environment changes and information indicates a sudden increase in rainfall or a sudden decrease in visibility, the vehicle should immediately slow down to ensure driving safety. If no signal of speed reduction is detected within a short period, it indicates that the driver's driving state is not focused enough and does not meet requirements, posing a driving safety risk. In such cases, timely reminders and warnings should be given to encourage the driver to improve their focus and drive attentively.

[0058] Furthermore, in some implementations, if it is determined that the driver's driving status does not meet the requirements, the driver is reminded, or the vehicle is forcibly slowed down to the set speed, or the vehicle is controlled to pull over to the side of the road.

[0059] The reminder to the driver includes, but is not limited to, one or more of the following methods:

[0060] Control the vibration of the driver's seat;

[0061] Play preset audio;

[0062] Display preset icons;

[0063] Control the windshield wiper swing.

[0064] The driver status monitoring method provided in this application combines vehicle speed and sudden weather changes to determine whether the driver's status meets the requirements.

[0065] In some implementations, when the vehicle is in intelligent driving mode, the solution provided in this embodiment is used to monitor whether the driver is slack off and completely relies on intelligent driving. When the driver is detected to be slack off, a timely reminder is given to ensure driving safety.

[0066] For example, when the target vehicle is in intelligent driving mode, steps S110-S120 are executed, i.e., in response to the detection of changes in the driving environment, the preset driving index information of the target vehicle is determined. Based on the preset driving index information and the changes in the driving environment, it is determined whether the driver's state meets the requirements; if it is determined that the driver's state does not meet the requirements, the driver is reminded. Here, the intelligent driving mode can refer to Level 2 or lower driver assistance technology as required by current national standards, or Level 3 or higher autonomous driving technology as required by current national standards. Specifically, Level 0 intelligent driving is called emergency assistance, which can provide prompts or briefly intervene in vehicle control to assist the driver in avoiding danger, but does not have the function of target and event detection and response (e.g., cruise control, electronic stability control, etc.). Level 1 intelligent driving is called partial driving assistance, which requires the driver and the intelligent driving system to jointly perform all dynamic driving tasks, and to supervise the behavior of the intelligent driving system and perform appropriate responses or operations (e.g., lane centering control, adaptive cruise control, etc.). Level 2 intelligent driving is called combined driving assistance, which requires the driver and the intelligent driving system to jointly perform all dynamic driving tasks, and to supervise the behavior of the intelligent driving system and perform appropriate responses or operations. Level 3 intelligent driving, also known as conditional intelligent driving, involves the intelligent driving system performing all dynamic driving tasks under designed operating conditions. When these conditions are about to deteriorate, the system promptly sends an intervention request to the support user. If the support user does not respond, measures to mitigate vehicle risks are taken as appropriate. Level 4 intelligent driving, also known as highly intelligent driving, requires no user response to intervention requests; the system automatically reaches a state of minimum risk. Level 5 intelligent driving, also known as fully automated driving, requires no user response to intervention requests; the system automatically reaches a state of minimum risk. For details, refer to GB / T40429-202, "Classification of Driving Automation for Automobiles."

[0067] For example, refer to Figure 2 As shown, when the vehicle enters a rainstorm section, if the automatic wipers are detected to accelerate; or when the vehicle enters a foggy section, if reduced visibility is detected; the system will continue to determine whether the vehicle speed has decreased. If the vehicle speed has not decreased, the system will remind the driver to take over the vehicle and exit the intelligent driving mode.

[0068] Specifically, the first step is to determine whether the vehicle is currently in intelligent driving mode. This can be determined by reading the status signals related to intelligent driving mode from the vehicle's control system. If the determination result is that the vehicle is not in intelligent driving mode, then the subsequent series of detection and judgment processes do not need to be executed, and the system can temporarily disregard the relevant situation; if the determination result is that the vehicle is in intelligent driving mode, the system proceeds to the next detection process.

[0069] For example, two specific signal inputs are detected. One is the automatic wiper speed change signal, which monitors the automatic wiper speed status in real time. The system records the speed changes of the automatic wipers within a short period of time (e.g., a 10-second time interval). When the system detects that the automatic wipers accelerate to a higher speed within these 10 seconds, it indicates that the external environment may have changed, such as sudden rainfall or increased rainfall.

[0070] Another method is fog patch recognition. This involves using cameras installed on the vehicle to monitor the road environment in real time through image processing and recognition algorithms. When the camera detects fog patches and the algorithm calculates that visibility has decreased to 50 meters, it indicates a significant reduction in visibility, posing a certain safety risk.

[0071] After detecting the two specific signal inputs mentioned above, the system further detects changes in vehicle speed. It monitors vehicle speed in real time by reading data from the vehicle's speed sensor. It determines whether the vehicle has experienced a significant speed reduction, such as a decrease from 120 km / h to 100 km / h. If a significant speed reduction is detected, it indicates that the vehicle system may have already made adjustments based on environmental changes, and the system does not need to take further special measures. If the vehicle has not experienced a significant speed reduction, the system proceeds to the next step of the judgment process.

[0072] If a specific signal is detected and the vehicle does not significantly reduce speed, the system will determine that the user may not be focused on driving. For example, the user may not be paying attention to road conditions as required for safe driving when the vehicle encounters adverse conditions, and may continue to rely on the intelligent driving system to drive.

[0073] Once the system determines that the user is not focused on driving, it will immediately prompt the user to take over the vehicle and exit intelligent driving mode through multiple means. Specific prompts include: issuing a warning sound through the center console; emitting a loud warning sound through the vehicle's center console audio system to attract the user's attention; displaying a warning message on the vehicle's central control screen in a flashing red manner, providing a strong visual reminder to the user; and activating the seat's built-in vibration device to further alert the user, making them truly feel the presence of danger and prompting them to take over the vehicle as soon as possible.

[0074] This embodiment applies to scenarios where the vehicle has entered the navigation system and the intelligent driving mode has been activated. In actual driving, weather conditions are complex and changeable. When encountering sudden weather changes, this embodiment determines whether the vehicle speed changes based on the navigation system. Specifically, it monitors the vehicle speed data displayed by the navigation system before and after the sudden weather change to analyze whether the driver is not paying attention. If the navigation speed changes abnormally, it may indicate that the driver has performed actions that violate intelligent driving rules.

[0075] Based on the same inventive concept, and corresponding to any of the methods in the above embodiments, this application also provides a driver status monitoring device. (Reference) Figure 3 The driver state monitoring device includes: a first determining module 310, used to determine preset driving index information of the target vehicle in response to the detection of changes in driving environment information; and a second determining module 320, used to determine whether the driver's driving state meets the requirements based on the preset driving index information and the changes in driving environment information.

[0076] Furthermore, it also includes a reminder module, which is used to remind the driver if it is determined that the driver's driving condition does not meet the requirements.

[0077] Specifically, the first determining module 310 is used to: determine the preset driving index information of the target vehicle in response to the detection of changes in the driving environment when the target vehicle is in intelligent driving mode.

[0078] Furthermore, the preset driving index information includes the change in vehicle speed; the first determining module 310 is used to obtain the vehicle speed data of the target vehicle at the target time from the vehicle speed sensor, navigation application or vehicle communication bus, and determine the change in vehicle speed based on the vehicle speed data.

[0079] Furthermore, the target time is determined based on the time when information about changes in the driving environment is detected.

[0080] Furthermore, the information regarding changes in the driving environment includes one or more of the following: visibility of the air decreases to a first preset value, rainfall increases to a second preset value, the oscillation speed of the windshield wipers of the target vehicle increases to a third preset value, entering a construction zone, entering a congested zone, and entering a speed-limited zone.

[0081] Furthermore, the second determining module 320 is specifically used to: if the change in vehicle speed indicates an increase in vehicle speed, or the speed at which the vehicle speed decreases does not reach a set value, then determine that the preset driving index information does not match the change information in the driving environment, and the driver's driving state does not meet the requirements.

[0082] Furthermore, the alert module is used to: control the vibration of the driver's seat;

[0083] Play preset audio;

[0084] Display preset icons;

[0085] Control the windshield wiper swing.
