Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobiles, in particular to an ambient light control method, equipment, device storage medium and vehicle. BACKGROUND

[0002] The ambient light of a vehicle not only makes the interior of the vehicle more beautiful, but also makes people feel more comfortable. At present, although the ambient light of a vehicle is beautiful, it has less interaction with the passengers in the vehicle, so that the driving experience of the user is single. Therefore, how to enhance the interaction between the passengers and the ambient light of the vehicle to improve the user experience of the ambient light of the vehicle is a technical problem to be solved. SUMMARY

[0003] The present application provides an ambient light control method, equipment, device storage medium and vehicle, which can dynamically adjust the working state of the ambient light in combination with the user's heart rate sign, realize effective interaction between the ambient light and the user, and improve the user experience.

[0004] To achieve the above-mentioned purpose, the first aspect of the present application provides an ambient light control method, comprising:

[0005] obtaining the heart rate information of the user through the ultra-wideband radio frequency signal;

[0006] adjusting the working state of the ambient light in the environment where the user is according to the heart rate information.

[0007] Therefore, the heart rate change of the user is directly detected through the ultra-wideband radio frequency signal, and then the working state of the ambient light is adjusted according to the heart rate change of the user. Therefore, the working state of the ambient light can dynamically change following the heart rate change of the user, and effective interaction between the ambient light and the user can be realized without the user's awareness.

[0008] As a possible implementation manner of the first aspect, the ambient light is the ambient light in the region corresponding to the position of the user in the environment. Therefore, the ambient lights around different users in the same environment can present different changes in state in response to the heart rate change of the user, thereby improving the user experience; in addition, the working state of the ambient light in the region corresponding to the position of the user can be adjusted without adjusting the working state of all ambient lights in the environment where the user is, thereby realizing energy saving.

[0009] As a possible implementation manner of the first aspect, the position of the user in the environment is obtained through the ultra-wideband radio frequency signal. Therefore, the position and the heart rate information of the user can be conveniently obtained simultaneously through the ultra-wideband radio frequency signal.

[0010] As a possible implementation manner of the first aspect, the heart rate information includes the absolute value of the heart rate, the average value of the heart rate and / or the heart rate change rate. Therefore, the heart rate change of each user in the same environment can be efficiently and accurately detected.

[0011] As a possible implementation manner of the first aspect, the absolute value of the heart rate is detected through the ultra-wideband radio frequency signal, the average value of the heart rate is obtained according to the absolute value of the heart rate, and the heart rate variation rate is obtained according to the absolute value of the heart rate or the average value of the heart rate.

[0012] As a possible implementation manner of the first aspect, adjusting the working state of the ambient light in the environment where the user is located according to the heart rate information comprises: when the position of the user in the environment belongs to the front row area of the vehicle cabin, adjusting the working state of the ambient light in the position corresponding area, so that the heart rate rising and falling trend caused by the change of the working state of the ambient light is opposite to the heart rate rising and falling trend reflected by the heart rate information; and / or, when the position of the user in the environment belongs to the rear row area of the vehicle cabin, adjusting the working state of the ambient light in the position corresponding area, so that the heart rate rising and falling trend caused by the change of the working state of the ambient light is the same as the heart rate rising and falling trend reflected by the heart rate information.

[0013] Therefore, the purpose of inhibiting the change of the user's emotion can be achieved by adjusting the working state of the ambient light, and the driving safety is improved; or, the purpose of resonating with the emotional state of the user can be achieved by adjusting the working state of the ambient light, and the comfort of the user riding in the vehicle is improved.

[0014] As a possible implementation manner of the first aspect, adjusting the working state of the ambient light in the environment where the user is located according to the heart rate information comprises: when the vehicle in which the user is riding is in a parking state, adjusting the working state of the ambient light in the vehicle cabin, so that the heart rate rising and falling trend caused by the change of the working state of the ambient light is the same as the heart rate rising and falling trend reflected by the heart rate information. Therefore, the comfort of the user riding in the vehicle can be improved by resonating with the emotional state of the user by adjusting the working state of the ambient light in the non-driving state.

[0015] As a possible implementation manner of the first aspect, the degree of change of the working state of the ambient light is proportional to the degree of change of the heart rate reflected by the heart rate information. Therefore, the degree of change of the working state of the ambient light can be synchronized with the degree of change of the heart rate, the change of the working state of the ambient light is significant when the heart rate changes fast, the change of the working state of the ambient light is subtle when the heart rate changes slowly, the brightness or color of the ambient light can better echo the change of the state of the user, and the user experience is further improved.

[0016] As a possible implementation manner of the first aspect, the working state of the ambient light comprises: the brightness, color, and / or flashing frequency of the ambient light. Therefore, the effect of the interaction between the ambient light and the user can be improved through one or more changes in presentation.

[0017] As a possible implementation manner of the first aspect, adjusting the working state of the ambient light in the environment where the user is located according to the heart rate information comprises one or more of the following:

[0018] When the heart rate information comprises a heart rate change rate, the second value of the parameter of the atmosphere lamp is determined according to the heart rate change rate, the preset maximum value of the parameter of the atmosphere lamp, the preset minimum value of the parameter of the atmosphere lamp, the preset maximum heart rate, the preset minimum heart rate, and the first value of the parameter of the atmosphere lamp;

[0019] When the heart rate information comprises a heart rate absolute value, the second value of the parameter of the atmosphere lamp is determined according to the heart rate absolute value, the preset maximum value of the parameter of the atmosphere lamp, the preset minimum value of the parameter of the atmosphere lamp, the preset maximum heart rate, and the preset minimum heart rate.

[0020] When the heart rate information comprises a heart rate mean value, the second value of the parameter of the atmosphere lamp is determined according to the heart rate mean value, the preset maximum value of the parameter of the atmosphere lamp, the preset minimum value of the parameter of the atmosphere lamp, the preset maximum heart rate, and the preset minimum heart rate.

[0021] Therefore, by flexibly setting the upper and lower limits of the heart rate and the upper and lower limits of the parameter of the atmosphere lamp, the value of the parameter of the atmosphere lamp can be adjusted through the heart rate information, so that the atmosphere lamp always works in a range acceptable to the user while realizing effective interaction between the atmosphere lamp and the user, and the user experience can be further improved.

[0022] As a possible implementation manner of the first aspect, the parameter of the atmosphere lamp is a wavelength, a brightness, or a working power of the atmosphere lamp. Therefore, the change in the presentation of the atmosphere lamp can be controlled through one or more parameters of the atmosphere lamp, so as to improve the effect of interaction between the atmosphere lamp and the user.

[0023] As a possible implementation manner of the first aspect, the heart rate information comprises a heart rate change rate, the change amount of the parameter of the atmosphere lamp is proportional to the heart rate change rate; or, the change amount of the parameter of the atmosphere lamp is inversely proportional to the heart rate change rate; or, the heart rate information comprises a heart rate absolute value, the change amount of the parameter of the atmosphere lamp is proportional to the difference between the heart rate absolute value and the preset minimum heart rate; or, the change amount of the parameter of the atmosphere lamp is proportional to the difference between the preset maximum heart rate and the heart rate absolute value; or, the heart rate information comprises a heart rate mean value, the change amount of the parameter of the atmosphere lamp is proportional to the difference between the heart rate mean value and the preset minimum heart rate; or, the change amount of the parameter of the atmosphere lamp is proportional to the difference between the preset maximum heart rate and the heart rate mean value; wherein, the change amount of the parameter of the atmosphere lamp is the difference between the second value and the first value.

[0024] Therefore, the degree of change in the working state of the atmosphere lamp can be associated with the degree of change in the heart rate of the user, the effective interaction between the atmosphere lamp and the user is enhanced, and the user experience can be further improved.

[0025] As one possible implementation of the first aspect, adjusting the ambient light's operating state in the user's environment based on heart rate information includes: determining the amount of change in the ambient light parameters based on the heart rate information; and determining a second value for the ambient light parameters based on the amount of change in the ambient light parameters. This allows the degree of change in the ambient light's operating state (e.g., brightness, color, etc.) to be correlated with the rate of change in the user's heart rate, thereby enhancing the effective interaction between the ambient light and the user.

[0026] As one possible implementation of the first aspect, the change in ambient light parameters is determined based on heart rate information. This includes: using the value corresponding to fa*x(range) / (f(max) – f(min)) as the change in ambient light parameter x, where fa represents the heart rate change rate, x(range) represents the range of ambient light parameter x, which is equal to the difference between the preset maximum value x(max) and the preset minimum value x(min) of ambient light parameter x, and (f(max) – f(min)) represents the heart rate range, which is equal to the difference between the preset maximum heart rate f(max) and the preset minimum heart rate f(min); " / " indicates division, * indicates multiplication, and "-" indicates subtraction. This allows the degree of change in the ambient light's operating state to be synchronized with the rate of change in the user's heart rate, thereby further enhancing the effective interaction between the ambient light and the user.

[0027] As one possible implementation of the first aspect, a second value of the ambient light parameter is determined based on the change in the ambient light parameter, including one of the following: using the sum of the first value of the ambient light parameter and the change in the ambient light parameter as the second value of the ambient light parameter; or using the difference between the first value of the ambient light parameter and the change in the ambient light parameter as the second value of the ambient light parameter. Therefore, different methods can be used to adjust the working state of the ambient light based on the heart rate variability rate as needed to achieve different effects such as suppressing changes in user emotions or resonating with the user's emotional state.

[0028] As one possible implementation of the first aspect, the heart rate information is either the absolute value of the heart rate or the mean heart rate; the change in the ambient light parameters is determined based on the heart rate information, including one of the following:

[0029] The value corresponding to x(range)*(f–f(min)) / (f(max)–f(min)) is used as the change in the ambient light parameter;

[0030] The value corresponding to x(range)*(f(max)–f) / (f(max)–f(min)) is used as the change in the ambient light parameter;

[0031] Wherein, x(range) is a range of the atmosphere lamp parameter x, x(range) is equal to a difference between x(max) of the atmosphere lamp parameter and a preset minimum value x(min), (f(max)-f(min)) is a heart rate range, which is equal to a difference between a preset maximum heart rate f(max) and a preset minimum heart rate f(min), f represents a heart rate average value or a heart rate absolute value, f(min) represents the preset minimum heart rate, and f(max) is the preset maximum heart rate; " / " represents division, "*" represents multiplication, and "-" represents subtraction. Thus, the atmosphere lamp working state can be adjusted based on the heart rate absolute value or the heart rate average value in different manners as needed, so as to achieve different effects such as suppressing changes in user emotions and resonating with user emotional states.

[0032] As a possible implementation manner of the first aspect, the second value of the atmosphere lamp parameter is determined according to the change amount of the atmosphere lamp parameter and the first value of the atmosphere lamp parameter, including: taking a sum of a preset minimum value of the atmosphere lamp parameter and the change amount of the atmosphere lamp parameter as the second value of the atmosphere lamp parameter. Thus, the adjustment of the atmosphere lamp working state can be implemented based on the heart rate absolute value or the heart rate average value.

[0033] As a possible implementation manner of the first aspect, the heart rate information contains a heart rate change rate, and the working state of the atmosphere lamp in the environment where the user is located is adjusted according to the heart rate information, specifically including: judging whether the heart rate change rate is greater than a preset jitter threshold; and when the heart rate change rate is greater than the jitter threshold, adjusting the working state of the atmosphere lamp in the environment where the user is located according to the heart rate information. Thus, subjective changes in the user's heart rate signs can be accurately captured, and the adjustment of the atmosphere lamp working state can be performed in response to such subjective changes, avoiding unnecessary adjustment of the atmosphere lamp working state, thereby further enhancing the interaction effect of the atmosphere lamp and the user.

[0034] As a possible implementation manner of the first aspect, the working state of the atmosphere lamp in the environment where the user is located is adjusted according to the heart rate information, including: sending first information, the first information being related to the heart rate information of the user and being used for adjusting the working state of the atmosphere lamp in the environment where the user is located. Thus, the adjustment of the atmosphere lamp working state can be implemented through other devices other than the UWB device, the implementation manner is more flexible, and the compatibility is better.

[0090] The words "first", "second", and the like or units A, units B, and the like similar words in the specification and claims are only used to distinguish similar objects, and do not represent a specific order of the objects. It can be understood that the specific order or sequence can be interchanged as long as it is allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0091] In the following description, the labels indicating steps such as S210, S220, and the like do not necessarily mean that the steps are executed in this order, and the order of the steps can be interchanged or the steps can be executed simultaneously as long as it is allowed.

[0092] The following first briefly analyzes some possible implementations of ambient light control.

[0093] In one possible implementation, the driver's left and right positions are photographed in real time in the vehicle cabin environment, and after a period of time of the photographed facial image of the driver, a pre-trained and calibrated mood judgment algorithm for the image screen is used to determine the driver's mood according to the facial image of the driver. If the driver's mood is not good, the ambient light is adjusted to make the ambient light present the effect corresponding to the bad mood, and if the driver's mood is good, the ambient light is adjusted to make the ambient light present the effect corresponding to the good mood. In this way, the purpose of improving the mood of the driver and improving the comfort experience of the driver is achieved. The defects of this way include: due to the limitation of the camera field of view and its installation position, it is only applicable to the driver and cannot be applied to other passengers; and the driver's mood is determined by facial expression, which is prone to false positives and can negatively affect the user experience of the driver. In addition, due to the limitation of the algorithm, it cannot be applied to different groups of people.

[0094] In a possible implementation, the force parameter information, speed parameter information, and temperature parameter information of the driver operating the accelerator pedal and the brake pedal, and the in-vehicle music parameter information are detected by vehicle sensors, the psychological state of the driver is comprehensively analyzed by using a predetermined organization model, and the ambient light is preset to be adjusted. The defects of this implementation include: multiple sensors need to be deployed for linkage detection and information sharing, and the above information can be obtained only in deep connection with the vehicle bus architecture, which has high deployment and development adaptation cost, and can only be implemented in front, only for the driver, and cannot be applied to other passengers. In addition, the ambient light adjustment is realized by a preset scheme, which cannot flexibly cope with different scenes and different groups of people.

[0095] Therefore, the embodiments of the present application can dynamically adjust the working state of the ambient light according to the heart rate information, and realize effective interaction between the ambient light and the user in the case that the user is not aware, thereby improving the user experience and the comfort experience of the user. By applying the embodiments of the present application to the vehicle cabin scene, the change in the user's vital signs can be automatically sensed, and the brightness, color, and other working states of the ambient light can be dynamically adjusted at the same time, thereby enhancing the experience identification of the passengers to the ambient light in the vehicle cabin, improving the user experience of the vehicle ambient light, and further improving the overall driving experience of the vehicle.

[0096] The present application can be applied to various scenes requiring flexible control of ambient light. The embodiments of the present application are particularly suitable for the cabin environment of a vehicle, a ship, an aircraft, or the like. Here, the "vehicle" includes any vehicle applicable to the embodiments of the present application. For example, the "vehicle" can include, but is not limited to, a private car, a bus, a passenger car, a high-speed rail, a subway, and the like, and the power type of the "vehicle" can be fuel-driven, pure electric, hydrogen fuel cell-driven, hybrid, and the like. Those skilled in the art can understand that any vehicle with a cabin can be regarded as a "vehicle" of the embodiments of the present application. In addition, the embodiments of the present application can also be applied to other application scenarios of ambient light, such as indoor scenes of office places, home places, entertainment places, or the like, or outdoor scenes of outdoor gatherings, and the like.

[0097] Figure 1 A schematic diagram of an exemplary application scenario of the embodiments of the present application is shown. Referring to FIG. 1, the schematic diagram of the exemplary application scenario of the embodiments of the present application is shown. Figure 1As shown, the vehicle 100 is installed with an ambient light array, and the cabin of the vehicle 100 is installed with an Ultra-Wideband (UWB) device 110. Through the embodiments of the present application, the heart rate of each occupant in the vehicle cabin can be detected by the UWB device 110, and then the working state of the ambient light in the vehicle cabin can be adjusted according to the heart rate information by the UWB device 110 and / or an electronic control unit (ECU) for vehicle body light control (not shown in the figure). It can be seen that by applying the embodiments of the present application to the vehicle 100, effective interaction between the ambient light in the vehicle cabin and the occupant can be realized without the occupant being aware, thereby effectively improving the driving comfort and driving safety of the vehicle 100.

[0098] In an embodiment of the present application, the UWB device 110 can be responsible for broadcasting ultra-wideband radio frequency signals and collecting reflected radio frequency information caused by the heart rate of the user. The position of each occupant in the vehicle cabin and the heart rate of each occupant can be detected in real time according to the spectrum information of the reflected radio frequency signals. The heart rate information of each occupant can be obtained by analyzing the heart rate of each occupant. Then, the UWB device 110 and / or the ECU can determine whether the occupant is in the front row or the back row by combining the position of each occupant. The wavelength, brightness, and other parameters of the ambient light array near the position of the occupant can be determined based on the heart rate information of the occupant in a corresponding manner. Finally, these parameters are notified to the corresponding ambient light array (for example, the ambient light controller in the ambient light array), so that the working state of the ambient light near the position of each occupant changes accordingly, thereby realizing effective interaction between the working state of the ambient light and the physical state of the occupant.

[0099] In some embodiments, the ambient light array can include an ambient light controller and a plurality of ambient lights, each ambient light being connected to the ambient light controller, and each ambient light working under the control of the ambient light controller. The specific structure of the ambient light array is not limited in the embodiments of the present application.

[0100] For example, as shown in Figure 1 , the ambient lights (not shown in the figure) in the ambient light array can be distributed at multiple positions in the vehicle cabin. For example, Figure 1 The positions ①, ②, ③, ④, ⑤, ⑥, ⑦, and ⑧ shown in the figure can be installed with ambient lights or ambient light arrays. The ambient lights at different positions can be controlled by different ambient light controllers or the same ambient light controller, that is, the ambient lights at different positions can present different working states or the same working state. It should be noted that the shape, structure, type, and installation method of the ambient light are not limited in the embodiments of the present application.

[0101] In some embodiments, the UWB device 110 can include a UWB antenna and a UWB processing module, and the UWB processing module can include a processor, a memory, a radio frequency amplifier, and the like. For example, as shown inFigure 1 The UWB device 110 can be installed near the center console of the A pillar of the vehicle cabin. In addition, the UWB device 110 can also be deployed at any other position of the vehicle cabin. In a specific application, the specific deployment position of the UWB device 110 can be determined freely according to the actual application scenario and application requirements. The specific form, deployment mode and structure of the UWB device 110 are not limited in the embodiments of the present application.

[0102] Exemplarily, the signal coverage range of a single UWB device 110 is limited. For a vehicle with a large cabin space, for example, multiple UWB devices 110 can be deployed, and each UWB device 110 is responsible for a different area. For example, for a luxury bus or a high-speed rail car with a large cabin space, a UWB device 110 can be deployed at a certain distance in the car, or a UWB device 110 can be deployed in each area after the area is divided according to the distribution of the ambient light array in the car. In this way, the ambient light control of a large space can be realized through multiple UWB devices 110.

[0103] In application scenarios such as home and office, the ambient light array has a large distribution area, and the deployment positions of the ambient light can be relatively scattered. For such scenarios, multiple UWB devices 110 can be deployed according to the distribution of the ambient light in the scenario, and each UWB device 110 can be responsible for the control of the ambient light in a specified area in the scenario.

[0104] The specific deployment mode and the number of UWB devices 110 can be flexibly set according to the requirements of the actual application scenario, and the embodiments of the present application are not limited in this regard.

[0105] Exemplarily, the ambient light array and the ECU for body light control, the UWB device and the ECU, and the ambient light array and the UWB device can communicate with each other through wireless or wired communication and the like. For example, the UWB device and the ECU, the ambient light array and the ECU, and the ambient light array and the UWB device can communicate with each other through various communication modes such as Ethernet, Bluetooth, WiFi network, cellular network, CAN bus, LIN bus and the like.

[0106] The specific embodiments of the present application will be described in detail below.

[0107] Figure 2 An exemplary flowchart of the ambient light control method according to an embodiment of the present application is shown. Referring toFigure 2 As shown, the exemplary flow of the ambient light control method of the embodiments of the present application can include:

[0108] In step S210, the vital information of the user is acquired.

[0109] In the embodiments of the present application, the vital information of the user can include but is not limited to heart rate information, pulse information, respiration information (e.g., respiration rate), body temperature information (e.g., mean body temperature, absolute body temperature, body temperature change rate), skin resistance, and any other information that can reflect the physiological characteristics or physical state of the user.

[0110] In the embodiments of the present application, the vital information can be detected in various applicable ways. For example, the vital information of the user can be directly detected by contact physiological detection sensors installed at positions such as the driver's seat, safety belt, steering wheel, steering mechanism, etc., wearable physiological detection sensors (e.g., smart bracelet, etc.), and non-contact physiological detection sensors (e.g., millimeter wave radar, infrared sensor, etc.). For another example, the vital information of the user can be indirectly detected by behavior data collected by torque sensors, steering angle sensors, accelerator pedal position sensors, braking force sensors, brake pedal position sensors, etc.

[0111] In some embodiments, the vital information of the user, such as heart rate information, pulse information, or respiration information, etc., can be detected by ultra-wideband radio frequency signals. Since the principle of detecting the vital information of the user by ultra-wideband radio frequency signals is based on the reflection characteristics of ultra-wideband radio frequency signals, this way can accurately, timely, efficiently, and non-invasively detect the vital information of the user.

[0112] In some embodiments, the heart rate information can be in various applicable forms. Specifically, the heart rate information can include but is not limited to heart rate change rate, heart rate absolute value, heart rate mean value, and heart rate change amount. Among them, the heart rate change rate can reflect the fast / slow trend and / or rising / falling trend of the heart rate change of the user within a certain time length, the heart rate absolute value can reflect the heart rate of the user at a certain moment, and the heart rate mean value can reflect the heart rate of the user within a certain time length. Here, the heart rate absolute value can be detected by ultra-wideband radio frequency signals, the heart rate mean value can be obtained according to the heart rate absolute value, the heart rate change rate can be obtained according to the heart rate absolute value or the heart rate mean value, and the heart rate change amount can be obtained according to the heart rate absolute value or the heart rate mean value.

[0113] In some embodiments, the heart rate change rate fa can be obtained by the following formula (1):

[0114] fa = (f-f0) / t (1)

[0115] Wherein, f can represent the mean heart rate of a period T2, f0 can represent the mean heart rate of a period T1 before T2, and t is the length of a single period (e.g., 10 seconds); or, f can represent the absolute value of the heart rate at a time t2, f0 can represent the absolute value of the heart rate at a time t1 before t2, and t is the length of time between t1 and t2.

[0116] As can be seen from the above, the heart rate change rate can be the ratio of the difference between the mean heart rate of a first period and the mean heart rate of a previous period to the length of a single period; or, the ratio of the difference between the absolute value of the heart rate at a first time and the absolute value of the heart rate at a previous time to the length of time between the two times. In this way, if the absolute value of the heart rate at the first time is lower than the absolute value of the heart rate at the previous time, or the mean heart rate of the first period is lower than the mean heart rate of the previous period, it indicates that the user's heart rate is decreasing, and accordingly, the heart rate change rate will be a negative value (e.g., -0.2 beats per second). If the absolute value of the heart rate at the first time is higher than the absolute value of the heart rate at the previous time, or the mean heart rate of the first period is higher than the mean heart rate of the previous period, it indicates that the user's heart rate is increasing, and at this time, the heart rate change rate will be a positive value (e.g., 0.4 beats per second). At the same time, the absolute value of the heart rate change rate is consistent with the speed of the user's heart rate increasing or decreasing, i.e., the faster the user's heart rate increases or decreases, the larger the absolute value of the heart rate change rate, and the slower the user's heart rate increases or decreases, the smaller the absolute value of the heart rate change rate. It can be seen that the heart rate change rate can directly reflect the speed and trend of the user's heart rate change.

[0117] It should be noted that the first period can be any period, and the first period and the previous period thereof can be two adjacent periods or two periods with a certain time interval (i.e., non-adjacent). The first time can be any time, and the previous time of the first time can be a time that is separated from the first time by a predetermined length of time or any length of time. Here, the length of a single period and the interval length between the first time and the previous time thereof can be pre-set.

[0118] In some embodiments, the heart rate change amount can be the difference between the mean heart rate of a first period and the mean heart rate of a previous period, or the heart rate change amount can be the difference between the absolute value of the heart rate at a first time and the absolute value of the heart rate at a previous time. Similarly to the heart rate change rate described above, the positive or negative of the heart rate change amount can reflect the increasing or decreasing trend of the user's heart rate change, and the absolute value of the heart rate change amount can reflect the speed of the user's heart rate change, i.e., the heart rate change amount can also reflect the speed and trend of the user's heart rate change.

[0119] In addition, the heart rate information can also be in any other form, as long as it can represent one or more of the following: user heart rate state, the speed of heart rate change, the trend of heart rate change. The specific form, content and calculation method of the heart rate information are not limited in the embodiments of the present application.

[0120] In some embodiments, the UWB device 110 can broadcast ultra-wideband radio frequency signals in real time, and the heart rate of a user within the signal coverage of the UWB device 110 will cause corresponding radio frequency reflections. The UWB device receives the radio frequency reflection signals caused by the user's heart rate, and the absolute value of the user's heart rate can be detected through the radio frequency reflection signals. Then, the average heart rate and the heart rate change rate of the user can be obtained according to the absolute values of the heart rate at different periods or different time points.

[0121] When the UWB device 110 detects the physiological characteristics of the human body (especially the monitoring of the absolute value of the heart rate and the respiratory frequency), the respiratory frequency and the harmonic frequency of the respiration are the main frequency components, the harmonic frequency of the respiration overlaps with the main frequency of the heartbeat, and the heart rate has a higher frequency compared with the respiration. Therefore, the respiratory frequency needs to be filtered out to obtain effective heart rate data. It has been found through verification that the phase-based algorithm can suppress the harmonic and avoid the intermodulation of the respiration and the heart rate. Therefore, in some embodiments, the UWB device 110 can detect the heart rate (for example, the absolute value of the heart rate) of the user by detecting the reflection pulse caused by the periodic displacement of the chest through the logarithmic method of phase change. In addition, the UWB device 110 can also detect the heart rate in other applicable ways, and the specific detection method of the heart rate is not limited in the embodiments of the present application.

[0122] In step S220, the working state of the ambient light in the environment where the user is located is adjusted according to the vital sign information.

[0123] Here, the working state of the ambient light in the environment where the user is located can be adjusted according to any one or more vital sign information of the user. For example, the working state of the ambient light in the environment where the user is located can be adjusted according to the heart rate information, the pulse information, the respiration information (such as the respiratory frequency), the body temperature information (for example, the average body temperature, the absolute value of the body temperature, the body temperature change rate), the skin resistance and / or any other information that can reflect the physiological characteristics or the physical state of the user.

[0124] In some embodiments, the working state of the ambient light in the environment where the user is located can be adjusted according to the heart rate information. Since the heart rate information can directly and accurately reflect the physical state and the needs of the user, the working state of the ambient light can be adjusted through the heart rate information, so that the working state of the ambient light can better respond to the changes in the vital signs of the user or the needs of the user.

[0125] In some embodiments, adjusting the working state of the ambient light in the environment where the user is located according to the heart rate information includes one or more of the following:

[0126] 1) determining a second value of the atmosphere lamp parameter according to the heart rate change rate, a preset maximum value of the atmosphere lamp parameter, a preset minimum value of the atmosphere lamp parameter, a preset maximum heart rate, a preset minimum heart rate and a first value of the atmosphere lamp parameter;

[0127] Here, the change amount of the atmosphere lamp parameter is proportional to the heart rate change rate; or, the change amount of the atmosphere lamp parameter is inversely proportional to the heart rate change rate. Wherein, the change amount of the atmosphere lamp parameter is the difference between the second value and the first value.

[0128] 2) determining a second value of the atmosphere lamp parameter according to the heart rate absolute value, a preset maximum value of the atmosphere lamp parameter, a preset minimum value of the atmosphere lamp parameter, a preset maximum heart rate and a preset minimum heart rate;

[0129] Here, the change amount of the atmosphere lamp parameter is proportional to the difference between the preset minimum heart rate and the heart rate absolute value; or, the change amount of the atmosphere lamp parameter is proportional to the difference between the preset maximum heart rate and the heart rate absolute value.

[0130] 3) determining a second value of the atmosphere lamp parameter according to the heart rate average value, a preset maximum value of the atmosphere lamp parameter, a preset minimum value of the atmosphere lamp parameter, a preset maximum heart rate and a preset minimum heart rate.

[0131] Here, the change amount of the atmosphere lamp parameter is proportional to the difference between the preset minimum heart rate and the heart rate average value; or, the change amount of the atmosphere lamp parameter is proportional to the difference between the preset maximum heart rate and the heart rate average value.

[0132] Therefore, the embodiment of the present application can make the change degree of the working state of the atmosphere lamp and the fast or slow degree of the change of the heart rate of the user be associated while the heart rate rising and falling trend caused by the atmosphere lamp is related to the heart rate rising and falling trend reflected by the heart rate information, and further enhance the effective interaction between the atmosphere lamp and the user.

[0133] In some embodiments, step S220 can include: step a1, determining a change amount of the atmosphere lamp parameter according to the heart rate information; step a2, determining a second value of the atmosphere lamp parameter according to the change amount of the atmosphere lamp parameter. In this way, by adjusting the parameter of the atmosphere lamp in the environment where the user is to the second value, the working state of the atmosphere lamp is related to the heart rate information.

[0134] Here, the atmosphere lamp parameter is used to control the working state of the atmosphere lamp, and the atmosphere lamp parameter can be but is not limited to the wavelength, brightness, working power and the like of the atmosphere lamp. Of course, the atmosphere lamp parameter can also be other types of parameters, such as the working time length, working voltage, flicker frequency and the like of the atmosphere lamp. The specific type of the atmosphere lamp parameter is not limited in the embodiment of the present application.

[0135] Here, the first value of the ambience light parameter represents the value of the ambience light parameter before the ambience light working state is adjusted, and the second value of the ambience light parameter represents the value of the ambience light parameter after the ambience light working state is adjusted. For example, the first value of the ambience light parameter can be the value of the ambience light parameter at the aforementioned time t1 or period T1, and the second value of the ambience light parameter can be the value of the ambience light parameter at the next time of the aforementioned time t1 or the next period of the period T1.

[0136] In some embodiments, when the heart rate information is the heart rate change rate in step a1, a value obtained by multiplying the ratio between the range of the ambience light parameter and the heart rate range by the heart rate change rate can be taken as the change amount of the ambience light parameter.

[0137] That is, the change amount of the ambience light parameter can be obtained by the following formula (2):

[0138] △x=fa*x(range) / (f(max)–f(min)), x(range)=x(max)-x(min) (2)

[0139] wherein △x represents the change amount of the ambience light parameter x, x(range) represents the range of the ambience light parameter x, x(max) represents the preset maximum value of the ambience light parameter x, x(min) represents the preset minimum value of the ambience light parameter x, the heart rate range is the difference between the preset maximum heart rate f(max) and the preset minimum heart rate f(min), and fa represents the heart rate change rate.

[0140] In specific applications, x(max), x(min), f(max), and f(min) can be taken as empirical values or set by the user, or x(range) and f(max)-f(min) can be directly taken as empirical values, or the respective values of x(range) and f(max)-f(min) can be directly set by the user. For example, the maximum heart rate of a human body is generally 190 beats per minute, which is about 3 beats per second, and converted into a unit period (for example, 10 seconds) is 30 beats per 10 seconds, that is, f(max) can be preset as 30 beats per 10 seconds. The minimum heart rate of a human body is generally 40 beats per minute, which is about 0.7 beats per second, and converted into a unit period (for example, 10 seconds) is 7 beats per 10 seconds, that is, f(min) can be preset as 7 beats per 10 seconds. Taking the wavelength λ (i.e., x=λ) as an example, λ(max) can be preset as the maximum wavelength of visible light (for example, 800 nanometres (nm)), and λ(min) can be preset as the minimum wavelength of visible light (for example, 400 nm). Taking the brightness B (i.e., x=B) as an example, x(range)=B(range), representing the range of brightness, and B(range) can be preset as 300 nits.

[0141] It can be seen from formula (2) that the change amount of the atmosphere lamp parameter changes in direct proportion to the heart rate change rate. Thus, the faster the user's heart rate changes, the greater the absolute value of the heart rate change rate, and the greater the absolute value of the change amount of the atmosphere lamp parameter. The degree of change in the working state of the atmosphere lamp will naturally be more significant. The slower the user's heart rate changes, the smaller the absolute value of the heart rate change rate, and the smaller the absolute value of the change amount of the atmosphere lamp parameter. The degree of change in the working state of the atmosphere lamp will naturally be more subtle. It can be seen that the degree of change in the working state (for example, brightness, color, etc.) of the atmosphere lamp can be synchronized with the speed of the user's heart rate change. In this way, the effective interaction between the atmosphere lamp and the user can be further enhanced without the user's awareness.

[0142] In some embodiments, step a2 can include one or both of the following:

[0143] 1) A positive correlation mode: the sum of the first value of the atmosphere lamp parameter and the change amount of the atmosphere lamp parameter is taken as the second value of the atmosphere lamp parameter, so that the influence of the working state of the atmosphere lamp on the user's heart rate is positively correlated with the heart rate change rate.

[0144] That is, the second value of the atmosphere lamp parameter can be obtained by formula (3) as follows. x' represents the second value (for example, the updated value) of an atmosphere lamp parameter x, and x represents the first value of the atmosphere lamp parameter x.

[0145] x' = x + Δx = x + fa * (x(range) / (f(max) - f(min))) (3)

[0146] In formula (3), the value of the atmosphere lamp parameter is positively correlated with the heart rate change rate. In this way, the influence of the adjusted working state of the atmosphere lamp on the user's heart rate is positively correlated with the user's heart rate change, which can achieve the purpose of promoting the user's heart rate change, thereby better resonating with the user's emotional state.

[0147] 2) A negative correlation mode: the difference between the first value of the atmosphere lamp parameter and the change amount of the atmosphere lamp parameter is taken as the second value of the atmosphere lamp parameter, so that the influence of the working state of the atmosphere lamp on the user's heart rate is negatively correlated with the heart rate change rate.

[0148] That is, the second value of the atmosphere lamp parameter can be obtained by formula (4) as follows. x' represents the second value (for example, the updated value) of an atmosphere lamp parameter x, and x represents the first value of the atmosphere lamp parameter x.

[0149] x' = x - Δx = x - fa * (x(range) / (f(max) - f(min))) (4)

[0150] In formula (4), the value of the ambience light parameter is negatively correlated with the heart rate change rate, so that the influence of the adjusted ambience light working state on the user's heart rate (i.e., the heart rate change caused by the ambience light) is negatively correlated with the heart rate change trend indicated by the heart rate change rate, thereby achieving the purpose of inhibiting the user's heart rate change.

[0151] Taking the wavelength and brightness as examples, the process of determining the second value of the ambience light parameter in step S220 can be shown in the following formulas (5) to (8):

[0152] λ' = λ - fa * (λ(max) - λ(min) / (f(max) - f(min))) (5)

[0153] B' = B0 - fa * (B(range) / (f(max) - f(min))) (6)

[0154] λ' = λ + fa * (λ(max) - λ(min) / (f(max) - f(min))) (7)

[0155] B' = B0 + fa * (B(range) / (f(max) - f(min))) (8)

[0156] Wherein, λ' represents the second value of the ambience light wavelength, λ represents the first value of the ambience light wavelength (assuming 700nm), fa represents the heart rate change rate, λ(max) represents the preset maximum value of the ambience light wavelength, which can be set as the maximum wavelength of visible light (such as 800nm), λ(min) represents the preset minimum value of the ambience light wavelength, which can be set as the minimum wavelength of visible light (such as 400nm), f(max) represents the preset maximum heart rate, f(min) represents the preset minimum heart rate, B0 represents the first value of the ambience light brightness, B' represents the second value of the ambience light brightness, B(max) represents the preset maximum value of the ambience light brightness, B(min) represents the preset minimum value of the ambience light brightness, B(range) represents the range of the ambience light brightness, and B(range) is the difference between the preset maximum value B(max) of the ambience light brightness and the preset minimum value B(min) of the ambience light brightness.

[0157] In some embodiments, when the heart rate information contains the mean heart rate or the absolute value of the heart rate, step a1 can include one or both of the following:

[0158] 1) The value obtained by multiplying the ratio between the range of the ambience light parameter and the range of the heart rate and the difference between the heart rate information and the preset minimum heart rate is taken as the change amount of the ambience light parameter. That is, as shown in formula (9), the change amount of the ambience light parameter positively correlated with the heart rate change can be obtained in this way.

[0159] Δx = x(range) * (f - f(min)) / (f(max) - f(min)) (9)

[0160] wherein f represents the absolute value of the current heart rate or the average heart rate.

[0161] 2) The value obtained by multiplying the ratio between the range of the atmosphere lamp parameter and the heart rate range and the difference between the preset maximum heart rate and the heart rate information is taken as the change amount of the atmosphere lamp parameter. That is, as shown in the following formula (10), the change amount of the atmosphere lamp parameter which is negatively correlated with the change of the heart rate can be obtained in this way.

[0162] Δx = x(range) * (f(max) - f) / (f(max) - f(min)) (10)

[0163] wherein f represents the absolute value of the current heart rate or the average heart rate.

[0164] In some embodiments, when the average heart rate or the absolute value of the heart rate is contained in the heart rate information, the sum of the preset minimum value of the atmosphere lamp parameter and the change amount of the atmosphere lamp parameter is taken as the second value of the atmosphere lamp parameter. That is, the second value of the atmosphere lamp parameter can be obtained by the following formula (11), and in this way, the atmosphere lamp parameter can be adjusted within a certain value range, the heart rate change caused by the change of the working state of the atmosphere lamp is related to the change of the heart rate of the user, and it can also be ensured that the working state of the atmosphere lamp is always within the range acceptable to the user, for example, the wavelength is within the visible light range and the brightness can be accepted by the user.

[0165] x' = x(min) + Δx (11)

[0166] As can be seen from formulas (9) to (11), the process of adjusting the working state of the atmosphere lamp according to the heart rate information in step S220 can include the following two implementation ways:

[0167] 1) The way positively correlated with the heart rate as shown in the following formula (12), by which the atmosphere lamp parameter is adjusted, the heart rate change caused by the working state of the atmosphere lamp before and after the adjustment is consistent with the trend of the change of the heart rate of the user, and then the purpose of the working state of the atmosphere lamp resonating with the emotion of the user is achieved:

[0168] x' = x(min) + (x(max) - x(min)) * ((f - f(min)) / (f(max) - f(min)) (12)

[0169] 2) The way negatively correlated with the heart rate as shown in the following formula (13), by which the atmosphere lamp parameter is adjusted, the heart rate change caused by the working state of the atmosphere lamp before and after the adjustment is opposite to the trend of the change of the heart rate of the user, and then the purpose of suppressing the change of the emotion of the user through the working state of the atmosphere lamp is achieved:

[0170] x' = x(min) + (x(max) - x(min)) * ((f(max) - f) / (f(max) - f(min)) (13)

[0171] Taking the wavelength and brightness as an example, the process of determining the second value of the atmosphere lamp parameter in step S220 can be represented by the following formulas (14) to (17):

[0172] λ' = λ(min) + (λ(max) - λ(min)) * (f - f(min)) / (f(max) - f(min)) (14)

[0173] B' = B(min) + (B(max) - B(min)) * (f - f(min)) / (f(max) - f(min)) (15)

[0174] λ' = λ(min) + (λ(max) - λ(min)) * (f(max) - f) / (f(max) - f(min)) (16)

[0175] B' = B(min) + (B(max) - B(min)) * (f(max) - f) / (f(max) - f(min)) (17)

[0176] Wherein, λ' represents the second value of the atmosphere lamp wavelength, λ(max) represents the preset maximum value of the atmosphere lamp wavelength, which can be set as the maximum wavelength of visible light (such as 800 nm), λ(min) represents the preset minimum value of the atmosphere lamp wavelength, which can be set as the minimum wavelength of visible light (such as 400 nm), f(max) represents the preset maximum heart rate, f(min) represents the preset minimum heart rate, f represents the mean or absolute value of the heart rate obtained by the UWB signal, B' represents the second value of the atmosphere lamp brightness, B(max) is the preset maximum value of the atmosphere lamp brightness, B(min) is the preset minimum value of the atmosphere lamp brightness, and B(range) is the range of the atmosphere lamp brightness, B(range) = B(max) - B(min).

[0177] For example, assuming that the user-defined preset maximum heart rate is 160 Hz / min, the preset minimum heart rate is 55 Hz / min, the preset maximum value of the ambient light wavelength is 800 nm, and the preset minimum value of the ambient light wavelength is 400 nm. Assuming that the average heart rate f of the user in the current period is 60 Hz / min, the ambient light wavelength should be adjusted to 419 nm according to formula (14). If the average heart rate f of the user in the next period is 80 Hz / min, the ambient light wavelength should be adjusted to 495 nm according to formula (14). As can be seen, when the ambient light wavelength is adjusted by formula (14), the absolute value of the ambient light wavelength increases as the heart rate of the user increases, and the color of the ambient light changes from blue to red. Since the color of the ambient light appears as red, it will promote the increase of the heart rate of the user. Therefore, the heart rate change trend caused by the adjusted working state of the ambient light is consistent with the heart rate change trend indicated by the average heart rate of the user, so that the working state of the ambient light can resonate with the emotion of the user. According to formula (16), the absolute value of the ambient light wavelength will decrease as the heart rate of the user increases, and the color of the ambient light will change from red to blue. Since the color of the ambient light appears as blue, it will inhibit the change of the heart rate of the user. Therefore, the heart rate change trend caused by the adjusted working state of the ambient light is opposite to the heart rate change trend indicated by the average heart rate of the user, so that the working state of the ambient light can inhibit the change of the emotion of the user.

[0178] In the above embodiments, the value of the ambient light parameter can be directly determined by the average heart rate or the absolute value of the heart rate. Not only can the ambient light parameter be adjusted within the range acceptable to the user, but also the heart rate change caused by the working state of the ambient light is directly related to the heart rate change trend of the user, so that effective interaction between the ambient light and the user can be achieved.

[0179] Here, the working state of the ambient light includes but is not limited to the brightness, color, and flicker frequency of the ambient light. The brightness of the ambient light can be controlled by the brightness parameter of the ambient light, the color of the ambient light can be controlled by the wavelength of the ambient light, and the flicker frequency of the ambient light can be controlled by the working power of the ambient light. Changing the ambient light parameters described above can achieve adjustment of the working state of the ambient light.

[0180] It should be noted that for different ambient lights or different ambient light arrays, the preset maximum value and the preset minimum value of various ambient light parameters can be the same or different, and can be flexibly set according to different application scenarios and different user needs.

[0181] In addition, if there are multiple atmosphere lamp parameters (for example, the atmosphere lamp has M atmosphere lamp parameters, M is an integer greater than 1), the various working states of the atmosphere lamp can be adjusted simultaneously through multiple atmosphere lamp parameters, or N (N is an integer greater than 0 and less than M) of them are selected to adjust the working state of the atmosphere lamp. That is, some working states of the atmosphere lamp can be adjusted, and all working states of the atmosphere lamp can also be adjusted. When adjusting, the selection of working states or atmosphere lamp parameters can be a default setting, or it can be set by the user, and the selection of working states or atmosphere lamp parameters can be different or the same for different atmosphere lamps or atmosphere lamp arrays.

[0182] In addition, if the change amount or the second value of the calculated atmosphere lamp parameter (for example, wavelength, brightness) is a floating point number, the calculation result can be rounded by various rounding methods suitable for the embodiments of the present application to obtain the atmosphere lamp parameter value that can be directly used to adjust the corresponding working state of the atmosphere lamp. For example, the intermediate results such as (x(range) / (f(max)-f(min))), ((x(max)-x(min)) / (f(max)-f(min))) can be rounded, or the calculation results such as the change amount Δx, the second value x of the atmosphere lamp parameter can be directly rounded. The specific processing method of the data in the process of determining the atmosphere lamp parameter value is not limited in the embodiments of the present application.

[0183] In some embodiments, step S220 can include: determining whether the heart rate change rate is greater than a preset jitter threshold; and adjusting the working state of the atmosphere lamp in the environment where the user is located according to the heart rate information when the heart rate change rate is greater than the jitter threshold. If the heart rate change rate is less than or equal to the jitter threshold, the adjustment of the working state of the atmosphere lamp can not be performed. Here, the jitter threshold can be preset as an empirical value or set by the user, for example, 1.5 times / 10 seconds.

[0184] Specifically, if the heart rate change rate exceeds the jitter threshold, it indicates that the user's heart rate change is subjective heart rate change, and the working state of the atmosphere lamp can be adjusted according to the heart rate change rate. If the heart rate change rate does not exceed the jitter threshold, it indicates that the user's heart rate change is natural heart rate change, which can be ignored. Therefore, the jitter threshold can be used to identify whether the user's heart rate change is natural heart rate change or subjective heart rate change, so as to accurately capture the subjective change of the user's vital signs and adjust the working state of the atmosphere lamp in response to such subjective change, avoid unnecessary adjustment of the working state of the atmosphere lamp, and further enhance the interaction effect between the atmosphere lamp and the user.

[0185] In some embodiments, the first information can be related to the heart rate information of the user, and the first information can be used to adjust the working state of the ambient light in the environment where the user is located. In this way, the first information can be provided to the external device (e.g., ECU or other vehicle-mounted device) to adjust the working state of the ambient light.

[0186] Here, the first information can include the heart rate information or the ambient light parameter. In some embodiments, the first information can include the heart rate change rate, the absolute value of the heart rate, and / or the average value of the heart rate as described above. By providing the first information to the external device, the external device can adjust the working state of the ambient light based on the heart rate information. In some embodiments, the first information can include the change amount of the ambient light parameter and / or the second value of the ambient light parameter as described above. By providing the first information to the external device, the external device can directly adjust the working state of the ambient light based on the change rate or the second value of the ambient light parameter.

[0187] It should be noted that the specific type of the first information or the type of the message carrying the first information is not limited in the embodiments of the present application. For example, the first information can be carried by a control message, a notification message, or an instruction, and can also be implemented as control information, notification information, or a pre-set instruction.

[0188] In some embodiments, in step S220, the ambient light can be the ambient light in the region corresponding to the position of the user in the environment. In this way, the working state of the ambient light in the region near the position of the user (e.g., the region near the position of the user in the vehicle cabin) can be adjusted in a suitable manner in combination with the position of the user, so that the ambient light around the users at different positions in the same environment changes in brightness, color, and the like in response to the heart rate of the user, thereby not only meeting the individual needs of multiple users in the same environment, but also achieving individual control of the ambient light without the user's awareness. In addition, only the ambient light in the region corresponding to the position of the user can be adjusted as needed, without adjusting the working state of all ambient lights in the environment where the user is located, thereby achieving energy saving.

[0189] In some embodiments, the position of the user in the environment is obtained through the ultra-wideband radio frequency signal. That is, in step S210, the position of the user in the environment can also be detected through the ultra-wideband radio frequency signal. In this way, the position and the heart rate information of the user can be obtained simultaneously through the UWB device by simultaneously detecting the heart rate and the position of the user through the ultra-wideband radio frequency signal, and the position and the heart rate information of the user are directly associated, without the need for other processing to associate them, and the error association between the heart rate information and the position can also be avoided, which not only has low hardware cost, but also has high efficiency and less errors.

[0190] In some embodiments, the positions of the users in the environment can be located by broadcasting the ultra-wideband radio frequency signals, and the relative distances of the users in the environment are obtained, which are distances of the users relative to the UWB device 110. In specific applications, the positions of the users in the environment can be directly represented by the relative distances of the users, or the specific positions of the users in the environment can be calculated by combining the specific position of the UWB device 110 in the environment and the relative distances of the users, and the specific positions are taken as the positions of the users, which can be represented by three-dimensional coordinates of a predetermined coordinate system. For example, in a vehicle cabin, the specific positions can be represented by three-dimensional coordinates of a vehicle cabin coordinate system.

[0191] Specifically, the UWB device 110 broadcasts the ultra-wideband radio frequency signals and receives the radio frequency reflection signals caused by the heart rates of the users, and the distances of the users relative to the UWB device 110 are obtained based on the time delays and intensities of the radio frequency reflection signals.

[0192] In some embodiments, the positions of the users in the environment can also be detected by other components such as lasers, radars, image sensors, ultrasonic sensors, etc., and the positions of the users in the environment are associated with the heart rate information of the users. In specific applications, the specific acquisition methods of the positions of the users, the association methods of the positions and the heart rate information, etc. are not limited in the embodiments of the present application.

[0193] For example, in a vehicle cabin, the users are in a static state, and in order to more accurately detect the positions of the users in the vehicle cabin, in some embodiments, the positions of the static human bodies are located by the UWB device 110, and the distances dis(x) of the users in the vehicle cabin relative to the UWB device 110 are obtained. For example, the UWB device 110 can use a multi-static human body target physiological sign signal echo model method to locate the positions of the static human bodies, and thus the relative distances dis(x) of the users in the vehicle cabin are obtained. Of course, in specific applications, other methods can also be used to detect the positions of the users according to the scene requirements. The specific methods for detecting the positions of the users are not limited in the embodiments of the present application.

[0194] In some embodiments, in step S220, when the user's position in the environment belongs to the front-row area in the vehicle cabin, the working state of the ambient light in the position corresponding area is adjusted, so that the influence of the working state of the ambient light on the user's heart rate is negatively correlated with the heart rate change. Here, the negative correlation refers to that the influence of the working state of the ambient light on the rising and falling trend of the user's heart rate (i.e., the heart rate change caused by the working state of the ambient light) is opposite to the rising and falling trend reflected by the heart rate information, that is, when the heart rate information reflects that the user's heart rate is in an upward trend, the adjusted working state of the ambient light can play a role in inhibiting the user's heart rate from rising, and when the heart rate information reflects that the user's heart rate is in a downward trend, the adjusted working state of the ambient light can play a role in inhibiting the user's heart rate from falling. In this way, the user's heart rate change can be inhibited by adjusting the working state of the ambient light, so that the user's emotional state remains stable.

[0195] In some embodiments, in step S220, when the user's position in the environment belongs to the rear-row area in the vehicle cabin, the working state of the ambient light in the position corresponding area is adjusted, so that the influence of the working state of the ambient light on the user's heart rate is positively correlated with the heart rate change. Here, the positive correlation refers to that the influence of the working state of the ambient light on the rising and falling trend of the user's heart rate (i.e., the heart rate change caused by the working state of the ambient light) is the same as the rising and falling trend indicated by the heart rate change rate, that is, when the heart rate change rate indicates that the user's heart rate is in an upward trend, the working state of the ambient light can play a role in promoting the user's heart rate to rise, and when the heart rate change rate indicates that the user's heart rate is in a downward trend, the working state of the ambient light can play a role in promoting the user's heart rate to fall. In this way, the working state of the ambient light can resonate with the user's emotional state, which helps to improve the user's comfort experience.

[0196] In the above embodiments, the positive correlation and the negative correlation can be only for the rising and falling trend, and the degree of change of the working state of the ambient light can always be synchronized with the speed of the user's heart rate change.

[0197] In some embodiments, the ambient lighting's operating state can be adjusted appropriately based on the user's location in the environment. Taking a vehicle cabin as an example, assuming the UWB device 110 is installed near the center console on the A-pillar of the vehicle cabin, it can be determined whether the user's relative distance dis(x) to the UWB device 110 is greater than a predetermined distance threshold d(min). If dis(x) is less than or equal to the predetermined distance threshold d(min), it can be determined that the occupant's position belongs to the front row area of ​​the vehicle cabin. In this case, the ambient lighting's operating state can be adjusted in a way that is negatively correlated with heart rate to remind the driver to stay alert and improve driving safety. If dis(x) is greater than the predetermined distance threshold d(min), it can be determined that the occupant's position belongs to the rear row area of ​​the vehicle cabin, i.e., in the passenger seat. In this case, the ambient lighting's operating state can be adjusted in a way that is positively correlated with heart rate to help the user rest fully and improve user comfort. Therefore, this embodiment of the application can execute different ambient lighting operating state adjustment logics by identifying the user's distance from the UWB device, so that users in different positions in the vehicle cabin receive completely different ambient lighting feedback experiences, thereby simultaneously improving driving safety and ride comfort.

[0198] In some embodiments, step S220 may include: when the vehicle in which the user is riding is parked, adjusting the operating state of the ambient lighting in the vehicle's cabin so that the effect of the ambient lighting's operating state on heart rate is positively correlated with the rate of change of heart rate. In this way, when the vehicle is parked, controlling the operating state of the ambient lighting can help the user get sufficient rest and improve the user's comfort experience.

[0199] by Figure 1 For example, if the vehicle is detected to be in neutral (N) gear, indicating that the vehicle is in driving mode, and if a passenger's heart rate variability is detected to be 2.5 beats / 10 seconds within a unit cycle (e.g., 10 seconds), exceeding the fluctuation threshold, it is determined to be a subjective heart rate variability. Simultaneously, based on the passenger's distance from the UWB device 110, it is determined that the passenger is located in the rear passenger seat and to the left of the UWB device 110, belonging to the rear of the vehicle cabin. Based on the passenger's heart rate variability, the wavelength and / or brightness of the ambient lights in the area near the passenger's position (e.g., positions ⑤ and ⑥) can be adjusted in a positively correlated manner. Thus, if the passenger's heart rate decreases, the ambient lights near the passenger's position will change to blue light and decrease in brightness, helping the passenger to fall asleep or get sufficient rest, improving riding comfort; if the passenger's heart rate increases, the ambient lights near the passenger's position will change to red light and increase in brightness, resonating with the passenger's excitement through the ambient light's operating state, thus further enhancing the passenger's sense of well-being.

[0200] Still with Figure 1For example, if the vehicle is detected to be in neutral (N) gear, indicating it is in driving mode, and the driver's heart rate variability is detected to be 2.5 beats per 10 seconds (e.g., exceeding the fluctuation threshold), this is considered a subjective heart rate change. Simultaneously, based on the driver's distance from the UWB device 110, the driver is positioned to the left of the device, within the front passenger area. The wavelength and / or brightness of the ambient lights near the driver's position (e.g., positions ① and ②) can be adjusted in a negatively correlated manner based on this occupant's heart rate variability. Thus, when the vehicle is in driving mode, if the front passenger's heart rate decreases, the ambient lights near their position will change to red and increase in brightness, providing a warning effect; conversely, if the heart rate increases, the lights will change to blue and decrease in brightness, promoting a calming effect. This control of the ambient lighting can stabilize the emotions of the front passenger and improve driving safety.

[0201] Still with Figure 1 For example, if the vehicle is identified as being in P gear, it means that the vehicle is in a parked state, i.e., not in a driving state. At this time, the ambient lighting can be adjusted for each occupant in the vehicle cabin in the same way as the rear passengers mentioned earlier. In this way, the ambient lighting can resonate with the occupants' emotions, achieving effects such as assisting sleep or waking up, thereby improving the occupants' comfort experience.

[0202] As can be seen above, by recognizing the vehicle's gear status, the ambient lighting can be adjusted in a suitable way. By controlling the ambient lighting to present different changes in driving and non-driving states, different feelings can be brought to the driver and passengers, improving the driving comfort and driving safety of the vehicle.

[0203] Still with Figure 1 For example, a configuration switch option can be provided, through which the user can select the method for determining the ambient light parameters. For instance, when the switch option is selected, the user can default to the method mentioned above for adjusting the ambient light working state based on the mean heart rate or the absolute heart rate. That is, when the switch option is selected, the ambient light parameters will be determined by the methods mentioned above (12) to (13). When the switch option is not selected, the user can default to the method mentioned above for adjusting the ambient light working state based on the heart rate change rate. That is, when the switch option is selected, the ambient light parameters will be determined by the methods mentioned above (3) to (4).

[0204] Figure 3 A schematic flowchart illustrating another ambient lighting control method provided in this application is shown. See also... Figure 3 As shown, an exemplary flow of this ambient lighting control method may include:

[0205] In step S310, first information is received, the first information being related to heart rate information of the user, the heart rate information being obtained through the ultra-wideband radio frequency signal.

[0206] In step S320, the working state of the ambient light in the environment where the user is located is adjusted according to the first information.

[0207] In some embodiments, the first information includes the heart rate information, which can include a mean heart rate, an absolute heart rate and / or a heart rate change rate. Thus, the working state of the ambient light in the environment where the user is located can be adjusted according to the heart rate information. Specifically, the specific implementation of adjusting the working state of the ambient light in the environment where the user is located according to the heart rate information is the same as that of step S220, and will not be repeated here.

[0208] In some embodiments, the first information can include ambient light parameter information, the ambient light parameter information being obtained according to the heart rate information, the ambient light parameter information including a change amount of the ambient light parameter and / or a second value of the ambient light parameter, the ambient light parameter being a wavelength, a brightness or a working power of the ambient light. Thus, the working state of the ambient light can be directly adjusted through the ambient light parameter. Here, the specific implementation of obtaining the change amount and / or the second value of the ambient light parameter based on the heart rate information is the same as that of the foregoing, and will not be repeated here.

[0209] In some embodiments, the first information can further include a position of the user in the environment, so as to adjust the working state of the ambient light in combination with the position of the user. Here, the specific implementation of adjusting the working state of the ambient light in combination with the position of the user is the same as that of step S220, and will not be repeated here.

[0210] Figure 3 The ambient light control method shown not only enables effective interaction between the ambient light and the user, but also can be easily implemented through other devices (for example, an ECU) other than the UWB device, and has more flexible implementation and better compatibility. Figure 3 The ambient light control method shown is particularly suitable for a scenario where multiple UWB devices or ambient lights are deployed in a scattered manner.

[0219] In some embodiments, the degree of change of the working state of the ambient light is proportional to the degree of change of the heart rate reflected by the heart rate information.

[0220] In some embodiments, the working state of the ambient light includes the brightness, the color, and / or the flashing frequency of the ambient light.

[0221] In some embodiments, the first adjusting unit 420 can be specifically configured to:

[0222] When the heart rate information includes the rate of change of the heart rate, a second value of the parameter of the ambient light is determined according to the rate of change of the heart rate, a preset maximum value of the parameter of the ambient light, a preset minimum value of the parameter of the ambient light, a preset maximum heart rate, a preset minimum heart rate, and a first value of the parameter of the ambient light.

[0227] In some embodiments, the first adjusting unit 420 can be specifically configured to determine the variation of the ambience light parameter according to the heart rate information by: taking a value corresponding to fa*x(range) / (f(max)–f(min)) as the variation of the ambience light parameter x, wherein fa represents a heart rate variation rate, x(range) represents a range of the ambience light parameter x, which is equal to a difference between a preset maximum value x(max) and a preset minimum value x(min) of the ambience light parameter x, (f(max)–f(min)) represents a heart rate range, which is equal to a difference between a preset maximum heart rate f(max) and a preset minimum heart rate f(min); “ / ” represents division, “*” represents multiplication, and “–” represents subtraction.

[0228] In some embodiments, the first adjusting unit 420 can be specifically configured to determine the second value of the ambience light parameter by one of the following ways: 1) taking a sum of the first value of the ambience light parameter and the variation of the ambience light parameter as the second value of the ambience light parameter; and 2) taking a difference between the first value of the ambience light parameter and the variation of the ambience light parameter as the second value of the ambience light parameter.

[0229] In some embodiments, the first adjusting unit 420 can be specifically configured to determine the variation of the ambience light parameter according to the heart rate information by one of the following ways:

[0230] 1) taking a value corresponding to x(range)*(f–f(min)) / (f(max)–f(min)) as the variation of the ambience light parameter;

[0231] 2) taking a value corresponding to x(range)*(f(max)–f) / (f(max)–f(min)) as the variation of the ambience light parameter;

[0232] Wherein, x (range) is the range of the atmosphere lamp parameter x, x (range) is equal to the difference between x (max) of the atmosphere lamp parameter and the preset minimum value x (min), (f (max) -f (min)) is the heart rate range, which is equal to the difference between the preset maximum heart rate f (max) and the preset minimum heart rate f (min), f represents the mean heart rate or the absolute value of the heart rate, f (min) represents the preset minimum heart rate, and f (max) is the preset maximum heart rate; " / " represents division, "*" represents multiplication, and "-" represents subtraction.

Here, the first information can include the heart rate information or the information of the atmosphere lamp parameter. For example, the heart rate information can include but is not limited to the mean heart rate, the absolute value of the heart rate or the heart rate change rate. The information of the atmosphere lamp parameter can include but is not limited to the change amount of the atmosphere lamp parameter or the second value of the atmosphere lamp parameter, and the atmosphere lamp parameter can be the wavelength, the brightness and / or the working power of the atmosphere lamp.

[0236] In some embodiments, the first information can further include the position of the user in the environment. Here, the position of the user in the environment can be obtained through the ultra-wideband radio frequency signal.

[0237] Figure 5 A structure schematic diagram of another atmosphere lamp control device provided by an embodiment of the present application is shown. Referring to FIG. 5, Figure 5 As shown in the figure, the atmosphere lamp control device 500 provided by the embodiment of the present application can include:

[0238] The receiving unit 510 is configured to receive first information, the first information being related to the heart rate information of the user, and the heart rate information being obtained through the ultra-wideband radio frequency signal.

[0239] The second adjusting unit 520 is configured to adjust the working state of the atmosphere lamp in the environment where the user is located according to the first information.

[0240] In some embodiments, the first information can comprise heart rate information, for example, the first information can comprise but is not limited to a mean heart rate, an absolute heart rate, or a heart rate variability, etc. Thus, the ambience light control device 400 can determine a second value of the ambience light parameter based on the heart rate information in the manner described above, and then adjust the ambience light parameter to the second value.

[0241] In some embodiments, the first information can comprise information of the ambience light parameter determined based on the heart rate information. For example, the information of the ambience light parameter can comprise a change amount of the ambience light parameter and / or a second value of the ambience light parameter, and the ambience light parameter can be a wavelength, a brightness, and / or a working power of the ambience light. Thus, the ambience light control device 500 can directly adjust the ambience light parameter based on the information of the ambience light parameter.

[0242] In some embodiments, the first information can further comprise a position of the user in the environment. Here, the position of the user in the environment can be obtained through the ultra-wideband radio frequency signal. Thus, the second adjustment unit 520 can further adjust the working state of the ambience light in combination with the position of the user in the environment, and the adjustment manner is the same as that of the first adjustment unit 420 and the ambience light control method described above, which will not be repeated here.

[0243] In actual applications, the ambience light control device 400 and the ambience light control device 500 can be realized by software, hardware, or a combination of both. Specifically, the ambience light control device 400 and the ambience light control device 500 can be arranged in or realized by the electronic device described below. For example, the ambience light control device 500 can be arranged in or realized by the UWB device, and the ambience light control device 500 can be arranged in or realized by the ECU.

[0244] In the following, the specific implementation of the ambience light control in the embodiments of the present application will be described in detail taking the vehicle cabin scenario as an example.

[0245] Figure 6 A specific implementation process of the ambience light control in the vehicle cabin scenario is shown. Referring to FIG. 6, the specific implementation process of the ambience light control in the vehicle cabin scenario can include the following steps. Figure 6

[0246] The UWB device broadcasts an ultra-wideband radio frequency signal to the surrounding, and the heart rates of the passengers in the vehicle cabin cause radio frequency reflections, and the UWB device collects heart rate reflection spectrum data.

[0247] In the current period T1, the UWB device obtains the positions of the passengers in the vehicle cabin relative to the UWB device and the mean heart rate f1 of each passenger in the period T1 based on all the heart rate reflection spectrum data collected in the current period.

[0248] ​In the next period T2, the UWB device obtains the position of each occupant relative to the UWB device in the vehicle cabin and the average heart rate f2 of each occupant in the period T2 according to all the heart rate reflection spectrum data collected in the current period.

[0249] According to the average heart rate f1 and the average heart rate f2 of each occupant, the heart rate variation rate fa of each occupant is calculated according to formula (1), and it is determined whether the heart rate variation rate fa of each occupant is greater than the jitter threshold value. If the heart rate variation rate fa of an occupant is greater than the jitter threshold value, subsequent processing is continued. If the heart rate variation rate fa of all occupants is less than or equal to the jitter threshold value, the initial step can be returned.

[0250] For the occupant whose heart rate variation rate fa exceeds the jitter threshold, the following processing is performed: the UWB device sends an ambient light adjustment notification message to the ECU for controlling the ambient light array in the region corresponding to the position of the occupant, and the ambient light adjustment notification message carries the heart rate variation rate fa and / or the average heart rate f2 of the occupant. The ECU calculates a second value of the ambient light parameter, i.e. an updated value of the wavelength of the ambient light and an updated value of the brightness of the ambient light, according to the heart rate variation rate fa and / or the average heart rate f2 of the occupant and its position, and controls the ambient light array near the position of the occupant to emit light according to the updated wavelength value and the updated brightness value, so that the ambient light can present changes in color and brightness in the next period of the period T2, and the degree of change in color and brightness is proportional to the speed of the change in the heart rate of the occupant (for example, the absolute value of the heart rate variation rate fa), and the change in color and brightness has a negative or positive correlation with the change in the heart rate of the occupant.

[0251] For example, assuming that the heart rate variation rate fa of the occupant A is greater than the jitter threshold, it is determined according to the position of the occupant A whether the occupant A is in the front row region or the rear row region of the vehicle cabin, and an ambient light adjustment notification message is sent to the ECU for controlling the ambient light in the corresponding region, and the ambient light adjustment notification message carries the heart rate variation rate fa or the average heart rate f2 of the occupant A.

[0252] For example, the ECU can first identify the gear state of the vehicle, and if the vehicle is in the P gear state, the updated wavelength value and the updated brightness value of the ambient light are calculated according to formula (7)-(8) or formula (14)-(15), and the corresponding ambient light adjustment instructions are sent to the ambient light controller of the ambient light array near the position of the occupant A in the vehicle cabin. The ambient light controller will control the ambient light near the position of the occupant A to present the color corresponding to the updated wavelength value and the brightness corresponding to the updated brightness value in the next period, so as to achieve the purpose of emotional resonance with the occupant A.

[0253] If the vehicle is not in the P gear state but in the driving state, the ECU can determine whether the passenger A belongs to the front row area or the rear row area according to the position of the passenger A and the preset distance threshold, and if the passenger A belongs to the front row area, the wavelength update value and the brightness update value of the ambient light can be calculated according to the formula (5)-(6) or the formula (16)-(17), and the corresponding ambient light adjustment instruction can be sent to the ambient light array near the position of the passenger A in the vehicle cabin, and the ambient light controller in the ambient light array will adjust the wavelength and brightness of the corresponding ambient light according to the ambient light adjustment instruction, so that the ambient light near the position of the passenger A presents changes in color and brightness in the next period, so as to achieve the purpose of inhibiting the emotional change of the passenger A. If the passenger A belongs to the rear row area, the wavelength update value and the brightness update value of the ambient light can be calculated according to the formula (7)-(8) or the formula (14)-(15), and the corresponding ambient light adjustment instruction can be sent to the ambient light array near the position of the passenger A in the vehicle cabin, and the ambient light controller in the ambient light array will adjust the wavelength and brightness of the ambient light near the position of the passenger A according to the ambient light adjustment instruction, so that the ambient light near the position of the passenger A presents changes in color and brightness in the next period, so as to achieve the purpose of emotional resonance with the passenger A.

[0254] Figure 6 The above process can be executed in a loop in the example, and the dynamic changes of the ambient light color and brightness with the passenger's heart rate can be achieved, thereby improving the overall driving experience of the vehicle.

[0255] Figure 7 Another specific implementation process of ambient light control in a vehicle cabin scene is shown. Referring to Figure 7 , the specific implementation process of the embodiment is basically the same as Figure 6 , except that the ambient light processing performed on the passenger with a heart rate change rate fa exceeding the jitter threshold is directly implemented by the UWB device, and the UWB device can directly send the ambient light adjustment instruction to the ambient light array near the position of the passenger A, or the UWB device can transmit the ambient light adjustment instruction to the ambient light array near the position of the passenger A through the ECU.
