Technical Field

[0001] This application relates to the field of optoelectronic control technology, and more particularly to the field of lighting control technology, specifically to a lighting control method, device, and vehicle. Background Technology

[0002] Currently, in the field of optoelectronic lighting control, with the development of intelligent technology, people's demand for the precision of lighting control is also increasing. However, traditional lighting control schemes are relatively fixed, only able to make simple adjustments to the lighting mode based on preset modes or adjust the brightness based on ambient brightness, without considering the personalized lighting control needs of different users. Therefore, this leads to a poor personalized experience for users. Thus, there is an urgent need for a more effective lighting control method for lighting fixtures. Summary of the Invention

[0003] This invention provides a method, apparatus, and vehicle for controlling the light emission of a lamp, to at least solve the technical problem in related technologies where poor light emission performance of lamps leads to a weak user experience. The technical solution adopted in this application is as follows: In a first aspect, this application provides a method for controlling the light emission of a luminaire, comprising: determining the photosensitivity preference of a first target object based on target information; the target information including at least one previously executed luminaire light emission control scheme, and the light avoidance actions of the first target object after each of the at least one luminaire light emission control schemes is executed; the first target object is one of at least one second target object; the second target object is a living object within the reference radiation range of the luminaire; determining the self-attention weight allocation of the first target object to at least one light emission feature of the luminaire based on the photosensitivity preference; determining a target luminaire light emission control scheme based on the self-attention weight allocation; and controlling the luminaire using the target luminaire light emission control scheme.

[0004] Based on the aforementioned technical means, this application, by determining the photosensitive preferences of at least one target object within the reference radiation range of the luminaire, can more accurately obtain the self-attention weight allocation results of the first target object for different luminous emission characteristics of the luminaire, directly and effectively reflecting the target object's true needs and level of attention to different luminous emission characteristics. Based on this, determining the luminous emission control scheme for the luminaire allows it to meet the differentiated needs of different target objects, thereby improving the user experience.

[0005] In one possible implementation, determining the target luminaire's light emission control scheme based on self-attention weight allocation includes: constructing a luminaire light emission uniformity objective function corresponding to a first target object based on self-attention weight allocation; wherein the luminaire light emission uniformity objective function is used to maximize the luminaire light emission uniformity; the luminaire light emission uniformity is represented by at least one light emission feature; the at least one light emission feature is determined using the sequence of control variable values ​​of the luminaire; generating at least one luminaire light emission uniformity fusion objective function corresponding to a second target object based on the luminaire light emission uniformity objective function corresponding to the first target object; and determining the target luminaire's light emission control scheme using the luminaire light emission uniformity fusion objective function.

[0006] Based on the aforementioned technical means, this application constructs a lamp luminous uniformity objective function corresponding to the target object through self-attention weights. This enables the lamp luminous uniformity objective function to more accurately reflect the first target object's preference for different luminous characteristics, thereby maximizing luminous uniformity. Based on this, by fusing the lamp luminous uniformity objective function corresponding to at least one target object, a lamp luminous uniformity fusion objective function is obtained. This can take into account the needs of multiple target objects within the lamp's reference radiation range, making the output of the lamp luminous uniformity fusion objective function more in line with the group's needs, thereby determining a more effective luminous control scheme.

[0007] In one possible implementation, based on the lamp luminous uniformity objective function corresponding to the first target object, at least one lamp luminous uniformity fusion objective function corresponding to the second target object is generated, including: determining the attention weight corresponding to the first target object based on the object type of the first target object and the relative pose between the first target object and the lamp; and generating the lamp luminous uniformity fusion objective function based on the lamp luminous uniformity objective function and the attention weight corresponding to the first target object.

[0008] Based on the above technical means, this application analyzes the object type of the target object and the relative pose between the target object and the lamp, and can determine the attention weight of the target object based on information such as the gaze angle and gaze height of the target object to the lamp, so as to combine the lamp luminous uniformity objective function of the target object to generate a lamp luminous uniformity fusion objective function that can better reflect the attention of the first target object to the lamp.

[0009] In one possible implementation, the target luminaire illumination control scheme is determined using a luminaire illumination uniformity fusion objective function, including: constructing constraints on the luminaire illumination uniformity fusion objective function; wherein the constraints are used to constrain the characteristic value range of at least one luminous feature and the allowable temperature rise range of the luminaire; the temperature rise value of the luminaire is determined based on at least one luminous feature; based on the luminaire illumination uniformity fusion objective function and constraints, the sequence of control variable values ​​is optimized to obtain the optimal value sequence of the control variables; and based on the optimal value sequence of the control variables, the target luminaire illumination control scheme is determined.

[0010] Based on the above technical means, this application can improve the safety of the target lamp light emission control scheme by constructing the characteristic value constraint range of each light emission feature in the light emission uniformity fusion objective function and the allowable temperature rise range of the lamp.

[0012] Based on the aforementioned technical means, this application can more accurately reflect the relative pose relationship between the target object and the lamp by using the relative pose of the target object's eyeball and each light-emitting array of the lamp. Based on this, the lamp's light-emitting control scheme can be specifically determined according to the target object's position and angle, so as to meet the different lighting needs of target objects at different positions and angles.

[0013] In one possible implementation, the photosensitivity preference of the first target object is determined based on the target information, including: determining the environmental information of the environment in which the first target object is located; and determining the photosensitivity preference based on the target information, environmental information, and photosensitivity preference learning model.

[0014] Based on the aforementioned technical means, this application, by determining information such as ambient light in the environment where the target object is located, can more accurately grasp the actual situation of the target object, making the judgment of light sensitivity preference more consistent with reality. Furthermore, by combining at least one lighting control scheme previously executed by the target object with a light sensitivity preference learning model to determine the target object's light sensitivity preference, it is possible to utilize the target object's historical choices to uncover preference patterns, thereby making the determined light sensitivity preference more scientific and accurate.

[0038] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0039] The light-emitting control device for lamps provided in this application embodiment is used to control the light emission of vehicle lights (especially intelligent driving vehicles). Vehicles can also be referred to as vehicles, mobile carriers, electric vehicles (EVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), fuel cell vehicles (FCVs), autonomous vehicles, intelligent and connected vehicles (ICVs), driverless vehicles, etc.

[0040] In this application, the vehicle can be a sedan, a sport utility vehicle (SUV), a truck, a special vehicle (such as an ambulance, fire truck, police car, etc.), a driverless taxi, a smart connected bus, an autonomous logistics vehicle, an electric truck, etc. Furthermore, this method is also applicable to various special-purpose vehicles, such as agricultural vehicles, mining vehicles, forestry vehicles, airport vehicles, and port vehicles. This application does not impose specific limitations in this regard.

[0041] like Figure 1 As shown, the vehicle of this application includes: a light-emitting control device 101 for lamps, an information collection device 102, and lamps 103.

[0042] The luminous emission control device 101 is used to receive target information collected by the information acquisition device 102, including at least one previously executed luminous emission control scheme and the target object's light avoidance action after the execution of the luminous emission control scheme. Based on the target information, it determines the light sensitivity preference of the target object, determines the self-attention weight allocation of each target object for each luminous emission feature of the luminous 103 based on the light sensitivity preference, and determines the target luminous emission control scheme of the luminous 103 based on the self-attention weight allocation result, so as to perform luminous emission control of the luminous 103.

[0043] The information acquisition device 102 is used to acquire target information and transmit it to the lighting control device 101 of the lamp. The target information includes at least one previously executed lighting control scheme and the target object's light avoidance actions after the execution of the lighting control scheme.

[0044] The information acquisition device 102 is also used to acquire the light emission characteristics of different light emission arrays in the lamp 103 and transmit the light emission characteristic information to the light emission control device 101 of the lamp.

[0045] The aforementioned information collection device 102 is also used to connect to the vehicle system, capture the location information of the target object based on the camera, obtain the location information of the Bluetooth key using radio frequency signals to verify the location information of the target object, and obtain ambient light information based on the light sensor, etc.

[0046] After receiving the light emission characteristics, the light emission control device 101 of the lamp determines the target light emission control scheme for the lamp 103 based on the light emission characteristics and the self-attention weight allocation result, so as to control the lamp 103.

[0047] The luminaire 103 is used to control the light emission of the target luminaire according to the light emission control scheme determined by the luminaire light emission control device 101.

[0048] The aforementioned lamp 103 is a device used to provide lighting. Common lamps include chandeliers, wall lamps, table lamps, street lamps, vehicle taillights, and ambient lights.

[0049] The aforementioned light emission control includes controlling information such as the on / off control pulses, illumination angles, and luminous brightness of at least one light emission array in the luminaire.

[0050] In practical applications, the light-emitting control device 101 of the lamp can communicate with one or more information acquisition devices 102 and the lamp 103.

[0051] For ease of understanding, this application uses the communication connection between a light-emitting control device 101 and a light fixture 103 as an example for illustration.

[0052] As a feasible approach, Figure 1 The light-emitting control device 101 and the light fixture 103 are installed in the vehicle. The light-emitting control device 101 and the light fixture 103 can be functional modules integrated into the same device, or they can be independently installed devices. This application does not impose any limitations on the comparison.

[0053] It is easy to understand that when the light-emitting control device 101 and the lamp 103 are functional modules integrated within the same device, the communication method between the light-emitting control device 101 and the lamp 103 is the same as the communication between modules within the device. In this case, the communication process between the two is the same as the communication process when the light-emitting control device 101 and the lamp 103 are set up independently. For ease of understanding, this application mainly uses the example of the light-emitting control device 101 and the lamp 103 being set up independently for explanation.

[0054] As a feasible approach, Figure 1 The light-emitting control device 101 of the lamp can be installed on a terminal, a server, or other types of electronic devices.

[0055] When the lighting control device 101 of the lamp is located at a terminal, the terminal can be a device that provides data connectivity to vehicle users or vehicle owners, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The terminal can communicate with one or more core networks via a radio access network (RAN). The terminal can be a mobile terminal, such as a computer with a mobile terminal, or a mobile device that exchanges voice and / or data with the radio access network, such as a mobile phone, tablet computer, laptop computer, netbook, or personal digital assistant (PDA). This application does not impose any limitations on this.

[0056] When the lighting control device 101 of the lamp is installed on a server, the server can be a single server, or it can be a server cluster consisting of multiple servers. In some embodiments, the server cluster can also be a distributed cluster. This application does not impose any limitations on this.

[0057] It should be noted that the structure illustrated in the embodiments of this application does not constitute a limitation on the light-emitting control device 101 of the lamp. It may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0058] For ease of understanding, the light emission control method of the lamp provided in this application will be described in detail below with reference to the accompanying drawings.

[0059] Figure 2 This is a flowchart illustrating a lighting control method for a lamp according to an embodiment of this application, with reference to... Figure 2 The light emission control method of the lamp includes: S201. Based on the target information, determine the photosensitivity preference of the first target object.

[0060] The aforementioned target information includes at least one previously executed lighting control scheme, and the light avoidance action of the first target object after each lighting control scheme is executed.

[0061] The first target object mentioned above is one of at least one second target object; the second target object is a living object within the reference radiation range of the luminaire.

[0062] The aforementioned reference radiation range of the luminaire can be determined based on the accuracy of the luminous emission control of the luminaire.

[0063] For example, the second target object mentioned above includes objects such as people or animals that are within the reference radiation range of the lamp.

[0064] The aforementioned light sensitivity preferences are used to indicate the unique preferences and adaptations of different primary target objects to lighting environments.

[0065] In some embodiments, photosensitive preferences include preferences for light intensity, light color, and light uniformity.

[0066] The aforementioned light sensitivity preferences can be determined based on factors such as the physiological characteristics, psychological state, and life experiences of the primary target subject. For example, physiological characteristics include the eye's sensitivity to light.

[0067] As an achievable approach, the photosensitivity preference of a first target object is determined based on target information, including: determining the environmental information of the environment in which the first target object is located; and determining the photosensitivity preference based on a learning model of the target information, environmental information, and photosensitivity preference.

[0068] The aforementioned environmental information includes ambient lighting information, which is used to determine whether the environment in which the first target object is located is daytime or nighttime, and to determine the different light sensitivity preferences of the first target object based on the different environmental information.

[0069] In some embodiments, the photosensitivity preference learning model can be constructed based on machine learning, deep learning, or reinforcement learning.

[0070] For example, in the case where the photosensitivity preference learning model is constructed based on reinforcement learning methods, the lighting control scheme and the environmental information of the target object are defined as the state parameters of the photosensitivity preference learning model; the operation of adjusting the control variables of the lighting fixture (such as on / off control pulses, illumination angle, and luminous intensity) is defined as an action; a reward function is set according to the target object's light avoidance actions. For example, if the target object does not exhibit light avoidance actions, a positive reward is given; if light avoidance actions occur, a negative reward is given, and the stronger the avoidance action, the greater the negative reward. Based on this, a reinforcement learning agent is constructed, which selects actions to execute based on the current state and adjusts the decision-making strategy based on the reward feedback obtained after executing the actions. Through continuous interaction and learning with the target object and the lighting fixture, the agent gradually learns to select lighting control schemes that can satisfy the photosensitivity preferences of the target object.

[0071] As a feasible approach, the photosensitive preferences of the first target object can also be determined based on information such as the eye gaze direction, eye dwell time, and avoidance gesture dwell time.

[0072] S202. Based on photosensitive preferences, determine the self-attention weight allocation of the first target object to at least one luminous feature of the lamp.

[0073] The self-attention weight allocation described above assigns a weight value to each luminescence feature calculated based on the self-attention mechanism. The magnitude of the weight value reflects the importance of the luminescence feature in satisfying the photosensitivity preference of the first target object. The larger the self-attention weight value, the greater the influence of the corresponding luminescence feature on the photosensitivity preference of the corresponding first target object.

[0074] As one possible implementation, the aforementioned at least one light-emitting feature includes the average brightness of the luminaire and the key light features of each of the at least one light-emitting array included in the luminaire; the key light features include: average brightness, maximum brightness, minimum brightness, row brightness difference, column brightness difference, and the ratio of the average brightness of adjacent light-emitting arrays; wherein, the row brightness difference is used to indicate the difference in the average brightness between the farthest light-emitting rows; the column brightness difference is used to indicate the difference in the average brightness between the farthest light-emitting columns.

[0075] As a feasible approach, Figure 3 This is a schematic diagram of a light-emitting array according to an embodiment of this application; wherein, 301 is used to represent adjacent light-emitting arrays, and 302 is used to represent the same light-emitting array. The same light-emitting array includes multiple LEDs.

[0076] The average brightness of the corresponding light-emitting arrays mentioned above Where k is the number of light-emitting arrays in the lamp. This represents the number of LEDs in the same light-emitting array.

[0077] The ratio of the average brightness between the adjacent light-emitting arrays is ,generally ,in The sensitivity of the first target object to the average brightness difference of adjacent luminous features. ,default It can also be integrated into the vehicle's infotainment system for users to customize and adjust.

[0078] The above line brightness difference is The column brightness difference is ;in, This is the roll angle correction factor. This is the pitch angle correction factor; the light-emitting array includes m rows and n columns of LEDs; The average luminance of the m-th row; The average luminance of the nth column. This represents the average luminance of the first row. This represents the average luminance of the first column.

[0079] The aforementioned key optical characteristics also include the ratio between the minimum and maximum brightness values ​​of all light-emitting arrays in the luminaire. .

[0080] The aforementioned key light features also include the ambient illuminance of the luminaires. Ambient illuminance can be used as a criterion for determining the values ​​of other key light features. Specifically, when the ambient illuminance is less than a preset ambient illuminance, the average brightness, maximum brightness, minimum brightness, and row brightness difference of each luminous array are obtained. For example, the preset ambient illuminance can be set to 1500 lx.

[0081] The aforementioned key light characteristics also include the ratio of the average brightness of adjacent LEDs in the same light-emitting array to the average brightness of the current light-emitting characteristic.

[0082] As a feasible approach, the first target object pays different attention to different key light features, which results in different photosensitivity preferences and different self-attention weights for the corresponding luminescence features.

[0083] S203. Based on self-attention weight allocation, determine the target luminaire's light emission control scheme.

[0084] As an feasible approach, a target luminaire illumination control scheme is determined based on self-attention weight allocation, including: constructing a luminaire illumination uniformity objective function corresponding to a first target object based on self-attention weight allocation; wherein, the luminaire illumination uniformity objective function is used to maximize the luminaire illumination uniformity; the luminaire illumination uniformity is represented by at least one illumination feature; the at least one illumination feature is determined using the sequence of control variable values ​​of the luminaire; generating at least one luminaire illumination uniformity fusion objective function corresponding to a second target object based on the luminaire illumination uniformity objective function corresponding to the first target object; and determining the target luminaire illumination control scheme using the luminaire illumination uniformity fusion objective function.

[0085] The aforementioned sequence of control variable values ​​refers to a set of specific values ​​selected to describe each controllable variable during the process of controlling the light emission of the lamp.

[0086] The controllable variables include brightness, color temperature, flicker frequency, and illumination angle.

[0087] As another feasible approach, when there is only one living object within the reference radiation range of the luminaire, the luminaire luminous uniformity objective function corresponding to the first target object is used as the luminaire luminous uniformity fusion objective function.

[0088] As one feasible approach, based on the lamp luminous uniformity objective function corresponding to the first target object, at least one lamp luminous uniformity fusion objective function corresponding to the second target object is generated, including: determining the attention weight corresponding to the first target object based on the object type of the first target object and the relative pose between the first target object and the lamp; and generating the lamp luminous uniformity fusion objective function based on the lamp luminous uniformity objective function and the attention weight corresponding to the first target object.

[0089] As one possible approach, the first target object is one of at least one second target object. In the case where there is only one second target object, the lamp luminous uniformity objective function corresponding to the unique first target object is directly used as the lamp luminous uniformity fusion objective function.

[0090] As another possible approach, when the second target object includes two or more living objects, the attention weight of each target object is obtained, and the function is fused according to the attention weight of each target object and the corresponding lamp luminous uniformity objective function to obtain the lamp luminous uniformity fusion objective function.

[0091] For example, such as Figure 4 As shown, Figure 4 This is a schematic diagram illustrating the location of the second target object in an embodiment of this application. 1, 2, and 3 all refer to the second target object.

[0092] As an feasible approach, a target luminaire illumination control scheme is determined using a luminaire illumination uniformity fusion objective function. This includes: constructing constraints on the luminaire illumination uniformity fusion objective function; wherein the constraints are used to constrain the characteristic value range of at least one luminous feature and the allowable temperature rise range of the luminaire; the temperature rise value of the luminaire is determined based on at least one luminous feature; based on the luminaire illumination uniformity fusion objective function and constraints, the sequence of control variable values ​​is optimized to obtain the optimal value sequence of the control variables; and based on the optimal value sequence of the control variables, the target luminaire illumination control scheme is determined.

[0093] The allowable temperature rise range of the above-mentioned lamps is determined based on the maximum temperature range that the lamps can withstand. If the temperature of the lamps is within the allowable temperature rise range, then the lamps are in a safe operating state.

[0094] The above constraints also include the optimization step size and convergence conditions of the objective function for constraining the uniformity of light emission from the luminaires.

[0095] All of the above-mentioned target lighting control schemes can be adjusted using pulse width modulation (PWM) waves via a current converter (BDC). If the BDC function is limited, a microcontroller unit (MCU) or other controller can be placed inside the lighting fixture to complete the above adjustments. If cost is not a concern, the illumination angle of different light-emitting arrays in the lighting fixture can be adjusted by designing the printed circuit board (PCB) mounting structure as a mechanically movable structure.

[0096] S204. Control the lighting fixtures using the target lighting fixture light emission control scheme.

[0097] As an achievable approach, a target luminaire light emission control scheme is used to control the on / off control pulses, illumination angle, luminous brightness, and ambient illuminance information of at least one light-emitting array in the luminaire.

[0098] As an feasible approach, the actual energy consumption of the luminaire is determined based on the target luminaire's light emission control scheme. If the actual energy consumption is within the preset energy consumption range, the luminaire is controlled based on the target luminaire's light emission control scheme.

[0099] As another feasible approach, when the actual energy consumption exceeds the preset energy consumption range, the target luminaire's light emission control scheme is optimized so that the luminaire can be controlled according to the optimized target luminaire's light emission control scheme.

[0100] As another feasible approach, the light emission control scheme of the target luminaire is used to control the current flowing through each light emission array of the luminaire, and the light emission control of the luminaire is performed according to the different currents.

[0101] Based on the aforementioned technical means, this application, by determining the photosensitive preferences of at least one target object within the reference radiation range of the luminaire, can more accurately obtain the self-attention weight allocation results of the first target object for different luminous emission characteristics of the luminaire, directly and effectively reflecting the target object's true needs and level of attention to different luminous emission characteristics. Based on this, determining the luminous emission control scheme for the luminaire allows it to meet the differentiated needs of different target objects, thereby improving the user experience.

[0102] In one possible implementation, the luminaire includes at least one light-emitting array; the relative pose between the first target object and the luminaire is determined based on the relative pose between the eyeball of the first target object and each of the at least one light-emitting array; the luminaire illumination control scheme first executed in the target information is determined based on the relative pose between each of the second target objects and the luminaire and the luminaire illumination control model.

[0103] The aforementioned relative pose can be determined based on the tilt and pitch angles of the first target object's eyeball and each light-emitting array.

[0104] In some embodiments, Figure 5 This is a schematic diagram illustrating a pitch angle according to an embodiment of this application; Figure 6 This is a schematic diagram illustrating a roll angle in an embodiment of this application.

[0105] For example, when the first target object is farther away from the vehicle, the first target object will observe more visible light-emitting arrays. At this time, the light emission uniformity adjustment strategy focuses more on the overall light emission uniformity. The more areas of the visible light-emitting arrays involved in the adjustment, the closer the overall light emission uniformity is to 1. When the first target object is closer to the vehicle, there are fewer visible light-emitting arrays, and the area of ​​the visible light-emitting arrays involved in the adjustment is reduced. Considering energy saving, the brightness of the non-participating (i.e., unobservable) light-emitting arrays is reduced, and the participating arrays mainly focus on the observable light-emitting arrays.

[0106] in, The pitch angle between the center of each light-emitting array and the first target object. For each light-emitting array, the first The tilt angle between the center of each LED illumination and the first target object.

[0107] As one possible approach, when adjusting the illumination angle of the aforementioned light-emitting array, the angle can be increased or decreased based on the mechanical adjustment angle available inside the luminaire.

[0108] As one feasible approach, the state function for calculating the effective illumination state of the i-th LED in the aforementioned light-emitting array on the first target object is shown below:

[0109] in, For the first An LED state function, composed of the brightness of each LED and the effective illumination angle, is used to describe the effective luminous brightness of an LED. For the first LED brightness; The first in the light-emitting array The tilt angle between the center of each LED illumination and the first target object; The first in the light-emitting array The pitch angle between the center of the LED illumination and the first target object. For the first LED illumination angle compensation coefficient, Adjustments are typically made based on the LED's own light-emitting angle, usually taking... .

[0110] Based on the aforementioned technical means, this application can more accurately reflect the relative pose relationship between the target object and the lamp by using the relative pose of the target object's eyeball and each light-emitting array of the lamp. Based on this, the lamp's light-emitting control scheme can be specifically determined according to the target object's position and angle, so as to meet the different lighting needs of target objects at different positions and angles.

[0111] In some embodiments, when determining the light sensitivity preference of the first target object, the target information includes not only the light avoidance action of the first target object after each of the at least one luminaire light emission control schemes is executed, but also the first target object's evaluation of the luminaire's light emission.

[0112] The evaluation results of the above-mentioned luminescence evaluation include, but are not limited to, scores, satisfaction levels, and other methods.

[0113] For example, the above score can be defined as 1-9 points, and the level of satisfaction can be defined as "unacceptable", "acceptable", and "satisfactory". Both evaluation methods can provide feedback through Bluetooth key hardware switches, such as buttons or knobs, or through mobile apps to interact with the vehicle's infotainment system.

[0114] As an achievable approach, when perceptual preferences are determined based on the above-mentioned luminous emission evaluation results, the constraints of the objective function for the luminous emission uniformity of the first target object also include the number of evaluations and the target value of the luminous emission uniformity evaluation.
