It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0055] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0056] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprising a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0057] With the development of society and the improvement of people's living standards, consumers' personalized demands for cars are increasing. The development of intelligent technology enables cars to provide more diverse functions and configurations to meet consumers' personalized needs. As a unique interior element, vehicle ambient lighting not only improves the texture and aesthetics of car interiors through diverse colors and light and shadow effects, but also provides consumers with a personalized driving experience. However, the existing solutions lack the ability to adjust the lighting according to the evaluation index of human comfort in the car, making it difficult to ensure the visual comfort, driving safety and riding experience of drivers and passengers, and it is difficult to meet the diverse and intelligent needs of users.

[0058] In order to solve the problems in the prior art, the embodiments of the present application provide a vehicle atmosphere light control method, system and device. The vehicle atmosphere light control method provided by the embodiments of the present application is first introduced below.

[0059] Figure 1 FIG. 1 is a flow chart showing a first embodiment of the vehicle ambient light control method of the present application. Figure 1 As shown, the method comprises the following steps:

[0060] S11: Acquire in-vehicle environmental parameters and passenger subjective parameters, wherein the in-vehicle environmental parameters at least include in-vehicle temperature, air quality and humidity, and the passenger subjective parameters at least include passenger riding time;

[0061] Specifically, the in-car environmental parameters include at least the in-car temperature, air quality and humidity. These environmental parameters affect the human comfort experience. Therefore, it can be understood that other environmental parameters that affect the human comfort experience can also be obtained, such as in-car noise, original in-car light brightness, etc.

[0062] Optionally, to obtain in-vehicle environmental parameters such as in-vehicle temperature, a temperature sensor may be used to collect data in real time.

[0063] To obtain in-vehicle environmental parameters such as air quality, air quality-related sensors can be used to collect data in real time. Air quality parameters include volatile organic compounds (VOCs) content, benzene content, particulate matter concentration, CO concentration, CO 2 concentration, etc. You can choose to collect one or several of the parameters, depending on the actual situation. For example, you can only collect CO 2 concentration, using CO 2 Sensors collect CO in the car 2 concentration.

[0064] To obtain in-vehicle environmental parameters such as in-vehicle humidity, an air humidity sensor can be used to collect data in real time. In some other scenarios, an air temperature and humidity sensor can be used to obtain both in-vehicle temperature and humidity.

[0065] The subjective parameters of passengers at least include the passenger's riding time. Obviously, the length of riding time affects the human comfort experience. Therefore, it can be understood that other subjective parameters that affect the human comfort experience can also be obtained, such as passenger emotions, speech tone, etc. It should be noted that passengers refer to people riding in the vehicle, including the driver and other passengers.

[0066] Optionally, to obtain the subjective parameters of the passenger, the passenger image can be captured using vehicle-mounted cameras, image sensors, etc. to extract time feature values, facial feature values, etc., to further obtain the passenger's riding time, emotions, etc.; vehicle-mounted audio equipment, sound sensors, etc. can be used to obtain sound feature values, etc., to further obtain the passenger's voice tone, etc. It can be understood that different sensing devices can be used to collect data in real time according to different subjective parameters of the passenger.

[0067] In a specific application scenario, to obtain subjective parameters of passengers such as the passenger's riding time, a gravity sensor can be used to sense the time when the passenger gets on and off the bus, and then the passenger's riding time can be calculated, specifically including:

[0068] The seat gravity sensor is used to collect the gravity on the seat and compare it with the pre-set gravity threshold. When the gravity is greater than the gravity threshold, it is considered that the passenger has boarded the bus. When the gravity is lower than the gravity threshold and exceeds the preset time, it is considered that the passenger has got off the bus. The passenger's riding time is calculated based on the time the passenger gets on and off the bus.

[0069] Among them, the gravity is lower than the gravity threshold and exceeds the preset time means that if the gravity on the seat detected by the seat gravity sensor is lower than the gravity threshold and lasts for a period of time, it is considered that the passenger has got off the car, avoiding misjudgment due to the passenger's short-term departure from the seat.

[0070] It should be noted that the various sensors mentioned in this embodiment are divided into modules only according to the acquired parameters. These sensors can be relatively independent or integrated into one or several sensors, and the comparison is not limited.

[0071] S12: constructing a physical comfort evaluation index based on the in-vehicle environment parameters;

[0072] In step S11, the in-vehicle environmental parameters such as in-vehicle temperature, air quality and humidity are obtained, and a physical comfort evaluation index is constructed based on these in-vehicle environmental parameters. In a specific application scenario of this embodiment, Figure 2 As shown, the following steps are included:

[0073] S121: Set the vehicle interior temperature T 实际 With the preset temperature threshold T 舒适阈值 Perform difference calculation to obtain the temperature deviation e 1 =T 实际 -T 舒适阈值 ;

[0074] Optionally, the temperature threshold T 舒适阈值 It is the temperature value that makes people feel comfortable. It can be set according to the air conditioning mode. If the air conditioning mode is cooling mode, the comfortable temperature threshold is T 1 , if the air conditioning mode is heating mode, the comfort temperature threshold is T 2 .

[0075] S122: Air quality parameter is CO in the vehicle 2 concentration, the CO 2 Concentration C(CO 2 ) and the pre-set CO 2 Concentration threshold C 0 Calculate the difference and get CO 2 Concentration deviation 2 =C(CO 2 )-C 0 ;

[0076] As mentioned above, there are many different options for air quality parameters. Here, the air quality parameter is defined as the vehicle interior CO 2 Concentration, CO in the car 2 Concentration is an indicator for evaluating the air quality in the car. Its appropriate range affects human health and comfort. In order to maintain the air quality and human comfort in the car, CO 2 Concentration threshold C 0 , the real-time collected CO 2 Concentration and pre-set CO 2 Concentration threshold C 0 Perform difference calculation.

[0077] S123: Compare the humidity RH in the vehicle with the preset humidity threshold RH 0 Perform difference calculation to obtain humidity deviation e 3 =RH-RH 0 ;

[0078] Humidity threshold RH 0 It is the humidity value that makes people feel comfortable and healthy. The humidity RH in the car can be collected in real time by using a humidity sensor.

[0079] S124: According to the temperature deviation e 1 , CO2 concentration deviation e 2 , humidity deviation e 3 , calculate the physical comfort evaluation index E 1 , the calculation method is as follows:

[0080]

[0081] Among them, k 1 , k 2 , k 3 , k 4 is the weight coefficient, e 4 Other factors that affect human comfort.

[0082] e 4 Other factors that affect human comfort, such as seat space layout, in-car noise and other factors.

[0083] S13: constructing a subjective comfort evaluation index based on the passenger's subjective parameters;

[0084] Specifically, according to the passenger subjective parameters obtained in step S11, these passenger subjective parameters include one type of passenger riding time, or multiple types of passenger riding time, passenger emotions, etc. In a specific application scenario of this embodiment, the passenger subjective parameter is the passenger riding time, and step S13 is specifically as follows:

[0085] According to the calculation formula E 2 =K·k 5 t to obtain the subjective comfort evaluation index E 2 , where K is the personalized comfort adjustment coefficient, k 5 is the weight coefficient, and the personalized comfort adjustment coefficient is set according to individual differences and personal preferences.

[0086] The goal of the personalized comfort adjustment coefficient is to adjust human comfort.

[0087] S14: constructing a comprehensive evaluation index of human comfort based on the physical comfort evaluation index and the subjective comfort evaluation index;

[0088] Specifically, the comprehensive evaluation index of human comfort can be constructed by both the physical comfort evaluation index and the subjective comfort evaluation index, and influenced by these two factors. In other embodiments, the comprehensive evaluation index of human comfort can also be constructed based on the physical comfort evaluation index, the subjective comfort evaluation index, and other third evaluation indicators, wherein the other third evaluation indicators are other influencing factors that affect human comfort.

[0089] In a specific application scenario of the present embodiment, step S14 is specifically as follows: according to the calculation formula E=a 1 E 1 +a 2 E 2 The comprehensive evaluation index of human comfort is obtained, among which E 1 is the physical comfort evaluation index, E 2 is the subjective comfort evaluation index, a 1 、a 2 is the weight coefficient.

[0090] S15: Control the adjustment of parameters of the vehicle ambient light according to the comprehensive evaluation index of human comfort, so that the vehicle ambient light presents different lights.

[0091] Specifically, the parameter adjustment of the vehicle ambient light may be color adjustment, brightness adjustment, or both color and brightness adjustment.

[0092] Optionally, the vehicle atmosphere light is composed of multiple LED lamp beads, and the LED lamp beads include three primary colors of red, green and blue. By adjusting the current of the red, green and blue primary color LED lamp beads, the vehicle atmosphere light can present various colors and brightness.

[0093] In a specific application scenario of the first embodiment, Figure 3 As shown, the method of step S15 includes the following steps:

[0094] S151: Compare the comprehensive evaluation index of human comfort with a preset human comfort threshold;

[0095] Specifically, the human comfort threshold is set to E 0 The comprehensive evaluation index of human comfort calculated in S14 is E. 0 Make comparisons;

[0096] S152: If the comprehensive evaluation index of human comfort is less than or equal to the human comfort threshold, it indicates that the comfort level of the vehicle interior environment is in a suitable state, and at this time, the vehicle atmosphere lamp is controlled to emit a first light;

[0097] Specifically, if the comprehensive evaluation index E of human comfort satisfies E≤E 0, indicating that the comfort level of the interior environment of the car is in an appropriate state and people will not feel uncomfortable in the car. At this time, the vehicle atmosphere light is controlled to emit the first light.

[0098] Optionally, the first light refers to a light with a certain brightness and color. The vehicle atmosphere light includes a vehicle atmosphere light control module and a light source module. The vehicle atmosphere light control module receives a parameter adjustment signal output according to a comprehensive evaluation index of human comfort, and controls the light source module to emit lights of different colors and brightness according to the parameter adjustment signal. For example, if the parameter adjustment signal is a white signal, the light source module is controlled to emit white light of a certain brightness according to the white signal.

[0099] S153: If the comprehensive evaluation index of human comfort is greater than the human comfort threshold, indicating that the comfort level of the in-vehicle environment is in an unsuitable state, then the weights of the physical comfort evaluation index and the subjective comfort evaluation index in constructing the comprehensive evaluation index of human comfort are continuously compared;

[0100] Specifically, if the comprehensive evaluation index E of human comfort does not satisfy E≤E 0 , it indicates that the comfort level of the interior environment is in an unsuitable state and people will feel uncomfortable in the car;

[0101] According to the calculation formula E = a 1 E 1 +a 2 E 2 The comprehensive evaluation index of human comfort is obtained. The weight values ​​of physical comfort evaluation index and subjective comfort evaluation index are a 1 and a 2 , now we need to continue comparing a 1 and a 2 For further judgment.

[0102] S154: If the weight of the physical comfort evaluation index is greater than or equal to the weight of the subjective comfort evaluation index, it indicates that the influencing factor of the vehicle interior environment is large, and in this case, the vehicle atmosphere lamp is controlled to emit a second light;

[0103] Specifically, if a 1 ≥a 2 , indicating that the physical comfort evaluation index has a higher weight, which means that the environmental factors in the car affect the human comfort and make people feel uncomfortable. At this time, the vehicle atmosphere light is controlled to emit a second light.

[0104] Optionally, the second light refers to a light with a certain brightness and color, the brightness and color of the second light are at least partially different from the brightness and color of the first light, and the vehicle atmosphere light includes a vehicle atmosphere light control module and a light source module. The vehicle atmosphere light control module receives a parameter adjustment signal output according to a comprehensive evaluation index of human comfort, and controls the light source module to emit lights of different colors and brightnesses according to the parameter adjustment signal. For example, if the parameter adjustment signal is a green signal, the light source module is controlled to emit green light of a certain brightness according to the green signal.

[0105] Furthermore, a signal can be sent to the vehicle dashboard to control the vehicle dashboard to issue a prompt message, such as suggesting that the driver open the window to promote air circulation.

[0106] S155: If the weight of the physical comfort evaluation index is less than the weight of the subjective comfort evaluation index, it indicates that the influencing factors of the in-vehicle environment are small. At this time, the vehicle atmosphere light is controlled to emit the third light.

[0107] Specifically, if a 1 ≤a 2 , indicating that the subjective comfort evaluation index has a higher weight, which means that the driver and other passengers in the car sit for a long time, affecting human comfort and making people feel uncomfortable. At this time, the vehicle atmosphere light is controlled to emit a third light.

[0108] Optionally, the third light refers to a light with a certain brightness and color, the brightness and color of the third light are at least partially different from the brightness and color of the first light, and the brightness and color of the third light are at least partially different from the brightness and color of the second light. The vehicle atmosphere light includes a vehicle atmosphere light control module and a light source module, the vehicle atmosphere light control module receives a parameter adjustment signal output according to a comprehensive evaluation index of human comfort, and controls the light source module to emit lights of different colors and brightnesses according to the parameter adjustment signal. For example, if the parameter adjustment signal is a red signal, the light source module is controlled to emit red light of a certain brightness according to the red signal.

[0109] Furthermore, a signal can be sent to the vehicle dashboard to control the vehicle dashboard to issue a prompt message, such as advising the driver not to drive while fatigued.

[0110] Furthermore, a signal can be sent to the in-vehicle music system to control the in-vehicle music system to play music to relieve driver fatigue.

[0111] The vehicle atmosphere light control method of this embodiment adjusts the vehicle atmosphere light according to the comprehensive evaluation index of human comfort in the vehicle, taking into account multiple vehicle environment factors such as temperature, air quality, humidity, and individual subjective feelings such as riding time, which helps the driver to stay awake and alert, reduce the risk of accidents caused by fatigue driving, improve driving safety, and enhance the passenger riding experience. Furthermore, this embodiment can also control the instrument panel and the car music system to respond accordingly, thereby providing a more comfortable driving environment that conforms to human feelings and relieves driving fatigue.

[0112] See also Figure 4 The method provided in the second embodiment of the vehicle ambient light control method of the present application includes, in addition to steps S11 to S15 of the first embodiment, the method further includes:

[0113] S16: Controlling the vehicle instrument panel to issue a prompt message according to the comprehensive evaluation index of human comfort.

[0114] Specifically, the prompt information is set according to the comprehensive evaluation index of human comfort. For example, when the comprehensive evaluation index of human comfort shows that the human body is in an uncomfortable state, prompt information such as opening windows for ventilation or please do not drive while tired can be displayed.

[0115] Step S16 may be located after step S14 and simultaneously with step S15, after step S15, or before step S15, but this is not limited.

[0116] See also Figure 5 The third embodiment of the vehicle ambient light control method of the present application provides a method, which, in addition to steps S11 to S15 of the first embodiment, further includes:

[0117] S17: Controlling the in-vehicle music system to play music according to the comprehensive evaluation index of human comfort.

[0118] Specifically, the type of music played by the in-vehicle music system is set according to the comprehensive evaluation index of human comfort. For example, when the comprehensive evaluation index of human comfort shows that the human body is in an uncomfortable state, the in-vehicle music system is controlled to play soothing music, thereby providing a more comfortable driving environment that suits the human body and relieves driving fatigue.

[0119] Step S17 may be located after step S14 and simultaneously with step S15, after step S15, or before step S15, but this is not limited.

[0120] See also Figure 6 The method provided in the fourth embodiment of the vehicle ambient light control method of the present application includes, in addition to steps S11 to S15 of the first embodiment, the method further includes:

[0121] S18: Obtain the current ambient light brightness, and control the brightness of the vehicle ambient light according to the ambient light brightness.

[0122] Specifically, the light sensor is used to obtain the current ambient light brightness, and the brightness of the vehicle atmosphere light is controlled according to the current ambient light brightness. This method and the parameter adjustment of the vehicle atmosphere light in step S15 assist each other and jointly adjust the brightness of the vehicle atmosphere light to put the human body in the most suitable and comfortable environment.

[0123] In a specific application scenario of the first embodiment, Figure 7 As shown, L is defined as the current ambient light brightness, L 0 is the ambient light brightness threshold, L H is the maximum threshold of ambient light, L B is the minimum threshold of ambient light, the method comprises the following steps:

[0124] S181: Get the current ambient light brightness L;

[0125] S182: If L 0 <L<L H , then the brightness of the vehicle's ambient light is enhanced;

[0126] Specifically, the vehicle atmosphere light includes a vehicle atmosphere light control module and a light source module. The light source module is composed of multiple LED lamp beads. The LED lamp beads include three primary colors: red, green and blue. The vehicle atmosphere light control module receives a light brightness comparison signal, adjusts the RGB value of the LED lamp beads, and changes the brightness of the light by adjusting the combination of red, green and blue light, thereby enhancing the brightness of the vehicle atmosphere light.

[0127] S183: If L B <L<L 0 , the brightness of the vehicle's ambient light is controlled to decrease.

[0128] Specifically, the vehicle ambient light control module receives the light brightness comparison signal, adjusts the RGB value of the LED lamp bead, and changes the brightness of the light by adjusting the combination of red, green and blue light, so that the brightness of the vehicle ambient light is reduced.

[0129] Steps S181-S183 can be looped until the system controls the end instruction. The brightness adjustment of this method is to supplement the deviation of the brightness adjustment of the vehicle atmosphere light in the parameter adjustment method that solely relies on the comprehensive evaluation index of human comfort to control the vehicle atmosphere light during the day or at night, and to coordinate and correct it.
