[0002] With the rapid development of intelligent driving technology, driver assistance systems (ADAS) have been widely used in modern vehicles, significantly reducing driver workload. However, current ADAS cannot completely replace manual operation, so drivers still need to monitor the vehicle at all times. In actual use, drivers often over-rely on ADAS, resulting in situations such as falling asleep while driving or taking their hands off the steering wheel for extended periods. This puts the vehicle in a dangerous driving state, and because surrounding vehicles and pedestrians are unaware of this dangerous situation, they cannot take preventative measures, easily leading to accidents. Summary of the Invention

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0055] This application provides a vehicle-assisted driving warning method, applied to the vehicle. The vehicle typically includes a vehicle controller, an assisted driving indicator light, and an in-vehicle camera. The assisted driving indicator light is a special light installed on the exterior of the vehicle, usually displaying a blue-green or blue color (hence commonly referred to as a "small blue light"). When the vehicle's assisted driving function is activated, the assisted driving indicator light automatically illuminates, informing other vehicles and pedestrians that the vehicle is in assisted driving mode, thereby improving road safety and preventing accidents caused by others misjudging the vehicle's behavior. The in-vehicle camera is typically installed around the driver's side sun visor and can be used to capture images of the driver. The vehicle controller is used to execute the vehicle-assisted driving warning method provided in this application, such as... Figure 1 As shown, in some embodiments, the vehicle controller includes a processor 110, a memory 120, and a communication component 130, etc. The following describes each component separately:

[0056] The processor 110 may be a central processing unit (CPU), which can be used to execute the aforementioned vehicle-assisted driving warning methods.

[0057] The memory 120 can be various volatile or non-volatile memory, such as solid-state disk (SSD), dynamic random access memory (DRAM), etc. The memory can be used to store pre-stored data, intermediate data, and result data in the vehicle control processing, such as the driver's driving status data.

[0058] The communication component 130 can be a wired network connector, a wireless fidelity (WiFi) module, a Bluetooth module, a cellular communication module, etc. The communication component can be used to transmit control commands to control other devices, such as controlling the on / off state and illumination status of the driver assistance sign lights.

[0059] This application provides a vehicle-assisted driving warning method, such as Figure 2 As shown, in some embodiments, the method includes:

[0060] S201. In response to the vehicle being in assisted driving mode, turn on the vehicle's assisted driving indicator light.

[0061] In practice, the driver assistance indicator light is a dedicated light fixture installed at a specific location on the exterior of the vehicle. When the driver is detected to have activated a driver assistance function (such as adaptive cruise control or lane keeping assist), an activation signal is sent to the driver assistance indicator light, which then illuminates in a constant light pattern, clearly indicating to surrounding road users that the vehicle is in driver assistance mode using a specific color.

[0062] S202. Obtain the driver's driving status data. If, based on the driving status data, it is determined that the vehicle does not meet the specified safe driving conditions, control the assisted driving indicator light to emit a corresponding light warning signal to warn traffic participants near the vehicle that the vehicle is in a dangerous assisted driving state. The "not meeting the specified safe driving conditions" indicates that the vehicle is in an assisted driving state where the driver is not supervising the vehicle.

[0063] In specific implementation, the driver's driving status data includes the driver's image, which can be captured by the vehicle's in-vehicle camera. The process of determining that the vehicle does not meet specified safe driving conditions based on the driving status data includes: performing behavior detection on the driver based on the driver's image to obtain behavior labels for the driver's behavior. This can be done, for example, using a deep learning model (such as a convolutional neural network, trained on a large dataset of labeled driver behavior, capable of recognizing and analyzing driver images and directly outputting behavior classification results, i.e., behavior labels for the driver's behavior); when the behavior label belongs to a specified behavior label set (the driver behavior corresponding to the behavior label in the specified behavior label set is an action where the vehicle's assisted driving is not supervised, such as closing eyes, making a phone call, or taking both hands off the steering wheel), it is determined that the vehicle does not meet the specified safe driving conditions. At this time, it is necessary to warn nearby traffic participants (such as vehicles and pedestrians) that the vehicle is in a dangerous assisted driving state, and therefore control the assisted driving indicator lights to emit corresponding light warning signals. The light warning signals include, but are not limited to: light signals flashing at a specified flashing frequency (e.g., 10Hz), light signals emitting light at a specified emission wavelength (e.g., 400nm), and light signals emitting light at a specified luminous intensity (e.g., 1000cd / ㎡). That is, the light warning signals emitted by the auxiliary driving sign lights can be light signals emitting light at a specified flashing frequency, a specified emission wavelength, and a specified luminous intensity; or light signals emitting light at a specified flashing frequency and a specified emission wavelength; or light signals emitting light at a specified flashing frequency and a specified luminous intensity; or light signals emitting light at a specified emission wavelength and a specified luminous intensity; or light signals emitting light only at a specified flashing frequency, a specified emission wavelength, or a specified luminous intensity.

[0064] In this embodiment, by issuing a specific light warning signal when the driver is detected to be in an unsupervised assisted driving mode, the key information that the vehicle is in a "dangerous assisted driving state" can be promptly conveyed to surrounding vehicles, pedestrians, and other road users. This allows surrounding road users to perceive the risk in advance and take evasive or defensive driving measures, thereby effectively reducing the probability of traffic accidents caused by driver incapacity and creating a safer and more predictable road traffic environment. Current assisted driving systems primarily target the driver inside the vehicle and cannot effectively intervene when the driver is completely incapacitated (e.g., asleep).

[0065] In some embodiments, controlling the assisted driving sign light to emit a corresponding light warning signal includes:

[0066] Determine the duration for which the vehicle does not meet the specified safe driving conditions; control the driver assistance indicator light to emit a light warning signal corresponding to the duration.

[0067] In specific implementation, the duration for which the vehicle does not meet the specified safe driving conditions, i.e., the duration for which the vehicle is in an assisted driving state where the driver is not supervising the vehicle, is considered a threat to traffic safety if the vehicle remains in this dangerous assisted driving state for an extended period. Therefore, it is necessary to control the assisted driving indicator light to emit a light warning signal corresponding to the duration. Specifically, a specified flashing frequency of the light warning signal can be determined based on the duration, and the specified flashing frequency is positively correlated with the duration. The assisted driving indicator light is then controlled to emit a light warning signal at the specified flashing frequency, as shown in Table 1.

[0068] Table 1

[0069] Duration (seconds) Specify the blink frequency (Hz) 0＜t≤5 1 5＜t≤15 2 15＜t≤30 4 t＞30 6

[0070] Table 1 illustrates the positive correlation between the specified flashing frequency and the duration. The longer the duration and the higher the specified flashing frequency, the more obvious the light warning signal of the assisted driving sign light, which can enhance the warning effect on surrounding vehicles and pedestrians.

[0071] A designated emission wavelength for the light warning signal can be determined based on the duration, and the designated emission wavelength is positively correlated with the duration; the driver assistance indicator light is controlled to emit a light warning signal at the designated emission wavelength, as shown in Table 2:

[0072] Table 2

[0073] Duration (seconds) Specify emission wavelength (nm) 0＜t≤5 450 5＜t≤15 480 15＜t≤30 510 t＞30 540

[0074] Table 2 illustrates the positive correlation between the specified emission wavelength and the duration. Initially, the specified emission wavelength of 450nm is blue light, used to clearly indicate to surrounding road users that the vehicle is in assisted driving mode. As the duration increases, the specified emission wavelength increases, and the color of the assisted driving sign light gradually turns green. The green light warning signal is more easily perceived by the human eye, thus enhancing the warning effect on drivers of surrounding vehicles and pedestrians.

[0075] The specified luminous intensity of the light warning signal can be determined based on the duration, and the specified luminous intensity is positively correlated with the duration. The driver assistance sign light is then controlled to emit a light warning signal at the specified luminous intensity, as shown in Table 3.

[0076] Table 3

[0077] Duration (seconds) Specified luminous intensity (cd / ㎡) 0＜t≤5 1000 5＜t≤15 1500 15＜t≤30 2000 t＞30 2500

[0078] Table 3 illustrates the positive correlation between the specified luminous intensity and the duration. The longer the duration, the higher the specified luminous intensity, and the more obvious the light warning signal of the assisted driving sign light, which can enhance the warning effect on surrounding vehicles and pedestrians.

[0079] In this embodiment, by making the flashing frequency, emission wavelength, and emission brightness positively correlate with the duration of the dangerous situation, a strong and escalating visual stimulus can be created for surrounding vehicles and pedestrians. This dynamic change is more attention-grabbing and conveys a sense of urgency than a fixed signal, especially at high speeds or in complex road conditions, providing others with more reaction time and significantly reducing the risk of collision. The human eye is most sensitive to green light and has good recognition, making the light warning signal easier to perceive and shortening the reaction time of other road users. Different combinations of light parameters can effectively convey the "level" of danger. For example, a low-frequency, slow-flashing blue light may only indicate "decreased driver attention," while a high-frequency, fast-flashing, bright green light clearly warns "the vehicle is in a high-risk, out-of-control state." This differentiated information helps drivers behind to determine whether only slight vigilance is needed or immediate emergency evasive action is required.

[0080] In some embodiments, the method further includes:

[0081] The duration for which the vehicle does not meet the specified safe driving conditions is determined; in response to the duration being greater than or equal to a duration threshold, environmental data of the vehicle is acquired, a safe parking area for the vehicle is determined based on the environmental data, and the vehicle is controlled to drive into the safe parking area.

[0082] In specific implementation, the duration for which the vehicle does not meet the specified safe driving conditions, that is, the duration for which the vehicle is in an assisted driving state where the driver does not supervise the vehicle, when the duration is greater than or equal to a duration threshold (for example, the duration threshold can be set to 30 seconds), indicates that the vehicle is in a dangerous assisted driving state for a long time, which will threaten traffic safety. Therefore, environmental data of the vehicle is acquired. This environmental data typically includes 360° environmental images of the vehicle's surroundings captured by multiple cameras mounted on the vehicle. The environmental images can be processed by grayscale conversion, histogram equalization, and Gaussian filtering to enhance their quality. Then, a CNN convolutional neural network can be used to extract features such as road edges, obstacle contours, and traffic signs from the environmental images. Based on the SegNet semantic segmentation network, potential safe parking areas in the images are identified, including legal parking areas such as emergency lanes and roadside vacant lots. The pixel coordinates of the safe parking areas are accurately calibrated in the environmental image coordinate system. According to the pre-calibrated transformation relationship between the environmental image coordinate system and the vehicle coordinate system, the pixel coordinates of the identified safe parking areas are transformed from the environmental image coordinate system to the vehicle coordinate system to obtain the safe parking area coordinates in the vehicle coordinate system. Based on the safe parking area coordinates, the vehicle is controlled to drive into the safe parking area. Alternatively, environmental point cloud data can be collected based on the vehicle's LiDAR to perform a three-dimensional model of the vehicle's surrounding environment, resulting in an environmental model. When a safe parking area is identified in the environmental image, the location of the corresponding safe parking area is determined in the environmental model based on the pixel coordinates of the safe parking area in the environmental image, and the vehicle is controlled to drive into the safe parking area.

[0083] In this embodiment, when the driver may be unable to operate the vehicle due to fatigue, sudden illness, or other reasons, the vehicle is promptly moved to a safe area. This effectively avoids potential collisions and other accidents that could occur if the vehicle continues to operate in an unsupervised assisted driving mode, directly protecting the safety of vehicle occupants, other road users, and surrounding facilities.

[0084] In some embodiments, the method further includes:

[0085] Determine the cumulative duration during which the vehicle fails to meet specified safe driving conditions within a specified period;

[0086] In response to the accumulated duration being greater than or equal to a preset accumulated duration, the vehicle is controlled to play a first warning audio and a second warning audio. The first warning audio is a warning audio played to the driver through the in-vehicle multimedia device, and the second warning audio is a warning audio played to traffic participants near the vehicle through the out-of-vehicle multimedia device.

[0087] In practice, the calculation of the cumulative duration is based on a sliding time window mechanism. For example, with a specified period of 1 minute, the duration during which the vehicle does not meet the specified safe driving conditions is accumulated. When the cumulative duration is greater than or equal to the preset cumulative duration (for example, the preset cumulative duration can be set to 10 seconds), it indicates that the driver has failed to supervise the vehicle in assisted driving mode multiple times in a short period of time. This is usually due to the driver becoming drowsy and closing their eyes for extended periods. At this time, a first warning audio is played to the driver through the in-vehicle multimedia device. The first warning audio can be a low-frequency beep (500Hz) or a voice prompt (such as "Please take over the vehicle immediately"). The audio intensity of the first warning audio is positively correlated with the cumulative duration, as shown in Table 4.

[0088] Table 4

[0089] Cumulative duration (seconds) The audio intensity (dB) of the first warning audio. 10＜t≤15 30 15＜t≤25 40 25＜t≤35 50 t＞35 60

[0090] Table 4 illustrates the positive correlation between the audio intensity of the first warning audio and the cumulative duration. The longer the cumulative duration, the higher the audio intensity of the first warning audio. The audio stops playing only when the driver monitors the vehicle in assisted driving mode, which has a significant warning effect on the driver and avoids using a high-intensity first warning audio at the beginning, which could frighten the driver.

[0091] Simultaneously, a second warning audio message is played to road users (such as pedestrians and other vehicles) via external multimedia devices (e.g., dedicated external speakers installed on the front and rear bumpers) to alert those in the vicinity that the vehicle is in a dangerous assisted driving state. The second warning audio message can use a standardized tone to avoid confusion with existing vehicle signals (such as vehicle horn audio), for example, playing intermittent "beep-beep" sounds (frequency 800Hz, twice per second) with an audio intensity of 70dB. When the accumulated duration exceeds 30 seconds, it can switch to a continuous beeping sound (frequency 1200Hz, audio intensity 80dB) and be superimposed with a voice broadcast: "Please note, risk of vehicle loss of control."

[0092] In this embodiment, not only is a first warning audio message (inside the vehicle) directly alerting a potentially distracted or fatigued driver, but a second warning audio message (outside the vehicle) also warns surrounding vehicles and pedestrians. This significantly reduces the probability of traffic accidents caused by driver incapacity. For example, after hearing the voice prompt "Please note the risk of vehicle loss of control," vehicles behind will maintain a greater following distance or prepare to swerve, effectively avoiding rear-end collisions or other accidents.

[0093] In some embodiments, the method further includes:

[0094] In response to the fact that the accumulated duration is less than a preset accumulated duration, the difference between the accumulated duration and the preset accumulated duration is determined;

[0095] In response to the difference being less than or equal to a preset difference, determine the number of times the vehicle fails to meet the specified safe driving conditions within a specified period;

[0096] In response to the number of times being greater than or equal to a preset number of times, a correction coefficient for the preset cumulative duration is determined based on the number of times, and the product of the correction coefficient and the preset cumulative duration is used as the corrected preset cumulative duration. The correction coefficient is used to reduce the preset cumulative duration, and the correction coefficient is negatively correlated with the number of times.

[0097] In practice, the preset cumulative duration is usually the initial value set when the vehicle leaves the factory. Therefore, determining the driver's monitoring status of the vehicle's assisted driving mode by comparing the cumulative duration with the initially set preset cumulative duration may not be suitable for all drivers. For example, when some drivers are drowsy, they may close their eyes multiple times, but each time the eyes are closed for a short period of time, resulting in a cumulative duration that is less than the initial preset cumulative duration. Therefore, it may not be possible to trigger the control of the vehicle to play the first warning audio and the second warning audio, which still poses a significant risk. Therefore, when the accumulated duration is less than the preset accumulated duration, the difference between the accumulated duration and the preset accumulated duration is determined. When the difference is less than or equal to the preset difference (for example, the preset difference can be set to 3 seconds), it indicates that the driver has not monitored the vehicle's assisted driving mode, but the warning audio has not been triggered. To ensure vehicle driving safety, the number of times the vehicle fails to meet the specified safe driving conditions within a specified period is determined. If the number is greater than or equal to the preset number (the preset number can be set according to the driver's blinking frequency in a conscious state, such as the driver blinking an average of 2 times every 10 seconds in a conscious state, and if the specified period is 60 seconds, then the preset number can be set to 12 times), it indicates that the driver may not be monitoring the vehicle's assisted driving mode. In this case, a correction coefficient for the preset accumulated duration is determined based on the number of times. The product of the correction coefficient and the preset accumulated duration is used as the corrected preset accumulated duration. The corrected preset accumulated duration is less than the initially set preset accumulated duration, thereby improving the sensitivity of triggering the control of the vehicle to play the first and second warning audio. The correction coefficient is negatively correlated with the number of times, as shown in Table 5.

[0098] Table 5

[0099] frequency Correction factor (0-1) 12 0.95 15 0.90 18 0.8 21 0.6

[0100] Table 5 illustrates the negative correlation between the correction coefficient and the number of times ...

[0101] In this embodiment, by comprehensively analyzing the difference in duration and the frequency of the behavior, vehicle driving risks can be identified more acutely. For example, if a driver repeatedly closes their eyes or exhibits distracted behavior within a short period (such as an abnormal increase in blinking frequency to more than 12 times within 60 seconds), even if the cumulative duration does not reach the initial preset cumulative duration, a warning can be triggered earlier by reducing the preset cumulative duration (such as by multiplying by a correction coefficient of 0.95 to 0.6). This greatly enhances the early perception of potential risks, helps prevent traffic accidents caused by temporary driver incapacitation, and improves overall road safety.
