[0034] This application provides a method and related equipment for controlling vehicle ambient lighting, which solves the problem in the prior art that vehicle ambient lighting cannot be adjusted in real time.

[0035] To better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. Furthermore, it should be noted that, for ease of description, only the parts related to the present invention are shown in the drawings, not the entire structure.

[0036] Please see Figure 1 The present application provides a schematic flowchart of a method for controlling an in-vehicle ambient light, which specifically includes the following steps:

[0037] Step S110: In response to the control command of the vehicle ambient light, the real-time heart rate data of the vehicle user is obtained, wherein the real-time heart rate data includes pulse fluctuation data.

[0038] In some examples, step S110 above can be executed by the vehicle's central controller. For instance, the central controller receives control commands for the ambient lighting, which can be issued by the vehicle user via the central screen. It should be noted that the central controller, as the core of the vehicle's computation and control, enables information interaction and functional linkage between various electrical, hardware, and software layers within the vehicle. In this application, it is merely presented as a specific representation of a function and is not specifically limited. The control command includes the heart rate-based control method for the ambient lighting selected by the vehicle user. Based on the control command, the central controller can acquire the driver's real-time heart rate data using an electrocardiogram (ECG) tester and pulse pressure sensor installed on the steering wheel. This heart rate data includes pulse fluctuation data. It should be noted that, generally, human pulse fluctuation is equivalent to heart rate, so human heart rate data can be obtained from pulse fluctuation data. No specific limitations are made on the device or method for acquiring heart rate data.

[0039] Step S120: Adjust the working state of the vehicle ambient light in real time based on the pulse fluctuation data.

[0040] In some examples, the central controller acquires real-time heart rate data from an electrocardiogram (ECG) tester and pulse pressure sensor on the steering wheel. This real-time heart rate data includes pulse fluctuation data. Understandably, in actual driving situations, drivers need to frequently adjust the steering wheel, and there may be situations where the acquired heart rate data is missing due to the movement of the driver's hands. The central controller can use artificial intelligence algorithms and previously acquired heart rate data to simulate the missing heart rate data, ensuring the continuity of the acquired real-time heart rate data.

[0041] In step S120, the central controller adjusts the working status of the vehicle ambient light in real time according to the pulse fluctuation, and can intuitively display the driver's heart rate status through changes in the color and brightness of the vehicle ambient light.

[0042] Understandably, heart rate data, as a crucial indicator of the human heartbeat, is vital. The human heartbeat is continuous, reacts rapidly to changes in emotions and physical condition, and is less susceptible to external interference. Adjusting the ambient lighting in real-time based on heart rate allows the lights to reflect the driver's heart rate status. Other vehicle occupants can also intuitively understand the driver's current physical and emotional state from the ambient lighting's status. In cases of potential dangerous driving or sudden cardiac dysfunction, the ambient lighting's status will rapidly change according to the driver's heart rate, allowing other occupants to promptly recognize the danger and prepare accordingly. Furthermore, in situations where the driver may have underlying cardiac dysfunction, the ambient lighting's status will differ from that under normal heart rate conditions. This change in the ambient lighting's status allows other occupants to quickly assess the driver's heart rate and provide timely alerts to the driver's health. ， The driver can also recognize their own heart rate status by observing changes in the working status of the in-vehicle ambient lights. Furthermore, the lighting display of the in-vehicle ambient lights can be automatically controlled in real time based on the driver's heart rate fluctuations. This allows the in-vehicle ambient lights to play according to the driver's heartbeat fluctuations, enriching the expression of the in-vehicle ambient lights, better matching the atmosphere inside the vehicle, and increasing the interactive experience.

[0043] According to some embodiments, the above-mentioned real-time adjustment of the operating state of the vehicle ambient light based on the above-mentioned pulse fluctuation data includes:

[0044] Based on the above pulse fluctuation data, the electrocardiogram waveform of a single cardiac cycle was fitted.

[0045] The vehicle ambient light is turned on based on the rising waveform in the electrocardiogram waveform of a single cardiac cycle, and turned off based on the falling waveform in the electrocardiogram waveform of a single cardiac cycle.

[0046] In some examples, the aforementioned single cardiac cycle refers to the process from the start of one heartbeat to the start of the next heartbeat, i.e., one heartbeat process, and the aforementioned electrocardiogram waveform represents the electrocardiogram waveform within a single cardiac cycle. For ease of explanation, this application provides a schematic diagram of an electrocardiogram waveform within a single cardiac cycle, as shown below. Figure 2As shown. Within a single cardiac cycle, the electrocardiogram waveform includes P / QRS / T segments (P wave represents atrial electrical activity; QRS represents ventricular depolarization and excitation; T wave represents the cardiac repolarization process). The scheme proposed in this application considers the changes in peak amplitude of different segments, among which QRS has the largest amplitude variation and obvious level amplitude changes. Moreover, some abnormal cardiac functions can be identified from the changes in QRS peak amplitude and the widening of the duration. Therefore, this scheme is based solely on the fluctuation of QRS for control, but without specific limitations. The central controller can acquire the driver's pulse amplitude and pulse pressure change data in real time through the electrocardiogram tester and pulse pressure sensor on the steering wheel. The driver's pulse amplitude and pressure change data can be used to fit the electrocardiogram waveform of a single cardiac cycle of the driver using artificial intelligence algorithms.

[0047] It is understandable that, such as Figure 2 As shown, within a single cardiac cycle, i.e., one heartbeat, there is a complete P / QRS / T band. In this embodiment, the ambient lighting is adjusted according to the QRS wave. Under normal human conditions, the duration of the QRS wave is between 0.06s and 0.1s. The aforementioned QRS wave includes a rising QR waveform and a falling RS waveform. The central controller controls the ambient lighting to turn on during the rising QR waveform and controls it to turn off during the falling RS waveform. Within one QRS wave, the ambient lighting completes one on / off cycle.

[0048] For example, the driver's single cardiac cycle time is 0.6s, the QRS time is 0.1s, and the QRS position is approximately in the middle of the single cardiac cycle. The vehicle ambient light is adjusted in real time based on the electrocardiogram waveform of the single cardiac cycle. Within a continuous 0.6s time period, the vehicle ambient light completes one on and off cycle within 0.1s of the aforementioned time period.

[0049] To further explain, under normal circumstances, the QRS time is 0.1s. When the driver has some potential cardiac dysfunction, the QRS time will be widened. At this time, the time for the ambient light to turn on and off once will be longer. Vehicle users can observe the time for the ambient light to turn on and off once to intuitively determine that the driver may have some potential cardiac dysfunction, which can serve as a reminder to the driver.

[0050] Another example is that in the event of an emergency that causes the driver's heart rate to increase or the driver to suddenly experience cardiac dysfunction, the duration of a single cardiac cycle may be shortened, such as from 1 second to 0.8 seconds. That is, the time interval between the opening and closing of the ambient lights is shortened from 1 second to 0.8 seconds, and the frequency of opening and closing the ambient lights increases.

[0051] In some situations, the driver's heart rate increases. The ambient lighting in the vehicle adjusts the frequency of opening and closing in real time according to the electrocardiogram waveform of a single heartbeat cycle. Vehicle users can be aware from the increased frequency of the ambient lighting that the driver may have a sudden heart failure or an emergency on the road, so that they can take timely measures and improve driving safety.

[0052] According to some embodiments, the above-mentioned real-time adjustment of the operating state of the vehicle ambient light based on the above-mentioned pulse fluctuation data includes:

[0053] The above electrocardiogram waveform for a single cardiac cycle was fitted based on the above pulse fluctuation data.

[0054] The brightness of the vehicle ambient light is increased based on the rising waveform in the electrocardiogram waveform of a single cardiac cycle, and the brightness of the vehicle ambient light is decreased based on the falling waveform in the electrocardiogram waveform of a single cardiac cycle.

[0055] In some examples, the electrocardiogram waveform of a single cardiac cycle is determined by referring to the aforementioned method, and the brightness of the vehicle ambient light is controlled based on the rising and falling waveforms of the QRS complex of the electrocardiogram waveform.

[0056] For example, the driver's real-time single cardiac cycle electrocardiogram waveform is acquired. During the QR rising waveform of the QRS, the central controller controls the brightness of the vehicle ambient light to increase from 1 lx (lux, a unit of luminous intensity measurement) to 60 lx. During the RS falling waveform of the QRS, the central controller controls the brightness of the vehicle ambient light to decrease from 60 lx (lux, a unit of luminous intensity measurement) to 1 lx.

[0057] Understandably, when the peak-to-peak value of the QRS increases, the level signal recognized by the central controller increases. At this time, the central controller can reflect this by increasing the brightness of the vehicle's ambient lighting. Conversely, when the peak-to-peak value of the QRS decreases, the central controller can also reflect this by decreasing the brightness of the vehicle's ambient lighting.

[0058] Another example is that when a driver's abnormal cardiac condition may cause changes in the QRS peak, the ambient lighting can reflect this situation by increasing or decreasing its brightness. For instance, when the driver is in normal condition, the central controller adjusts the ambient lighting brightness from 1 lx to 50 lx and then back to 1 lx based on the rising and falling waveforms of the ECG QRS complex. However, when the driver's QRS complex is abnormal, causing a rise in the peak value, the central controller detects an increased peak level signal. In this case, the central controller adjusts the ambient lighting brightness from 1 lx to 80 lx and then back to 1 lx based on the rising and falling waveforms of the ECG QRS complex. The vehicle user can then become aware of the driver's abnormal QRS condition from the significant increase in ambient lighting brightness, thus providing a timely reminder to the driver to pay attention to their health.

[0059] According to some embodiments, the number of heartbeats in each preset cycle is determined based on the above-mentioned pulse fluctuation data;

[0060] The heart rate level of the current preset cycle is determined based on the number of heartbeats in the previous preset cycle.

[0061] The color of the vehicle ambient light is adjusted according to the heart rate level of the current preset cycle.

[0062] In some examples, the preset period can be 60 seconds, or 15 seconds, etc. For ease of explanation, this application embodiment selects a preset period of 60 seconds, but it is not specifically limited. The number of heartbeats can be equivalent to the number of pulse fluctuations in the human body. Referring to the number of heartbeats per minute, it can be divided into five heart rate levels: less than 60 beats per minute is the first level, 60 to 75 beats per minute is the second level, 76 to 85 beats per minute is the third level, 86 to 100 beats per minute is the fourth level, and more than 100 beats per minute is the fifth level.

[0063] For example, with a preset cycle of 60 seconds, if the driver's pulse fluctuation data determines that the heart rate during the preset cycle is 80 beats per minute, the heart rate level is at level three. This means the central controller will control the ambient lighting to be yellow during the next preset cycle (the next 60 seconds). When the driver is in a relaxed mood, the heart rate during the preset cycle drops to 65 beats per minute, and the heart rate level is at level two. This means the central controller will control the ambient lighting to change from yellow to green during the next preset cycle (the next 60 seconds). Furthermore, the central controller can also control the flashing of the ambient lighting based on the heart rate, enriching the visual effects of the ambient lighting.

[0064] By controlling the color change of the in-vehicle ambient lighting through the heart rate within a preset period, the ambient lighting can respond to the driver's mood changes based on the heart rate. When the mood is relaxed, the heart rate decreases and the ambient lighting is one color; when the mood is tense, the heart rate increases and the ambient lighting is another color. The ambient lighting better matches the atmosphere inside the vehicle, enhancing the interactive experience.

[0065] According to some embodiments, when the heart rate level of the current preset cycle exceeds the preset frequency level range, the vehicle ambient light alarm is controlled.

[0066] In some examples, referring to the aforementioned heart rate levels, the preset frequency levels can be Level 2, Level 3, and Level 4, which represent the normal range of heartbeats per minute for a human body. When the driver's heart rate level is Level 1 or Level 5, exceeding the preset frequency range, it is understandable that the driver's heart rate is abnormal. This could be due to an abnormal physical condition or an emergency situation during driving, causing the driver's heart rate to increase. In this case, the central controller can control the vehicle's ambient lighting to issue a warning, such as switching it to red and flashing it at a high frequency, to remind vehicle users of potential dangers and improve the safety awareness of vehicle occupants.

[0067] According to some embodiments, the heart rate in the previous preset cycle is converted into the respiratory rate in the previous preset cycle;

[0068] The brightness and dimming frequency of the vehicle ambient light in the current preset cycle is adjusted according to the number of breaths in the previous preset cycle.

[0069] In some examples, the medical conversion between human respiratory rate and heart rate is usually 1:4 or 1:5. This application uses 1:5 in its embodiment, but does not make any specific limitation.

[0070] For example, if the previous preset cycle is 30 seconds and the heart rate in the previous preset cycle is 40 beats per minute, the central controller converts the heart rate in the previous cycle into the number of breaths in the previous preset cycle at a ratio of 1:5, and determines the number of breaths in the previous preset cycle to be 8. The central controller can then control the brightness of the vehicle's ambient lighting to change 8 times within the current preset cycle.

[0071] Understandably, converting heart rate into respiratory rate and controlling the brightness of the ambient lighting to mimic breathing patterns based on this respiratory rate is a more efficient method than directly detecting human respiration. It eliminates the need for breathing detection devices and, by determining the respiratory rate based on the driver's heart rate, it accurately reflects the driver's current breathing rhythm, less susceptible to environmental interference. Adjusting the ambient lighting's brightness based on this rhythm improves the stability of the ambient lighting control. Furthermore, it demonstrates ambient lighting brightness changes related to actual human breathing rhythms without requiring additional breathing detection equipment.

[0072] According to some embodiments, any of the aforementioned methods for controlling vehicle ambient lighting further includes:

[0073] In response to the aforementioned operating instructions for the vehicle ambient lights, control the operating mode of the vehicle ambient lights.

[0074] In some examples, the vehicle interior features a variety of different ambient lighting styles, such as body ambient lighting, dashboard ambient lighting, center console screen ambient lighting, and panoramic sunroof ambient lighting. Vehicle users can control the ambient lighting in different locations within the vehicle by selecting different operating modes.

[0075] Understandably, vehicle users can issue different work commands to select different operating modes for the ambient lighting, controlling the ambient lighting in different locations within the vehicle to display different effects, thus enriching the expressive forms of the ambient lighting. Moreover, when there are fewer vehicle users, such as when there are only passengers in the front row, the ambient lighting can be controlled to only display on the dashboard or the center console screen, which saves on the vehicle's power resources while still fulfilling the function of ambient lighting in adjusting the vehicle's atmosphere.
