[0048] The present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0049] Please refer to Figure 1The present application also provides a light group control method, which can be applied to electronic devices, and each step of the method can be executed or implemented by the electronic device. Among them, the electronic device can be an electronic control system on a vehicle, or other control device, which can be flexibly determined according to the application scenario, and is not specifically limited here. In addition, the control object of the method is a light group, and the light group can be divided into multiple areas, each area can include one or more light strings, each light string can include one or more light areas, and each light area can include at least one lamp bead. A light area, as the smallest control unit, can be used as a bit, and the electronic device can use the bit to control all the lamp beads in a light area to light up or go out at the same time. For example, when the bit is assigned a value of 1, all the lamp beads in the light area are controlled to light up; when the bit is assigned a value of 0, all the lamp beads in the light area are controlled to go out.

[0050] The light group may be, but is not limited to, various types of vehicle lamps, decorative lights on the exterior of buildings, and indoor ambient lights. In the embodiment, taking the application scenario of a vehicle as an example, the light group may include an indoor ambient light, an outdoor ambient light, a tail light, a headlight, etc. in the vehicle, and the light group control method may include the following steps:

[0051] Step 110, when receiving a control instruction to operate in a specified lighting effect mode, obtaining target lighting effect data corresponding to the specified lighting effect mode from a driving database, wherein the driving database includes at least two types of lighting effect data;

[0052] Step 120, based on the control instruction and the target lighting effect data, determining the target light zone to be controlled in the light group and the control parameters corresponding to the target light zone, wherein the control parameters at least include the location information and the operation time information of the target light zone;

[0053] Step 130: Based on the control parameters, control the target light zone to operate in the specified lighting effect mode.

[0054] In this embodiment, since the driver database can include multiple lighting effect data, it can adapt to the drivers of multiple lighting effect modes. If the driver database is created in advance and the lighting effect data corresponding to various lighting effect modes are configured, even when facing light groups with different layouts, when the same lighting effect mode is used later, the lighting effect data in the driver database can still be used to achieve the corresponding lighting effect control. In this way, there is no need to independently develop corresponding driver software for light groups with different layouts, which is conducive to reducing the driver development cost and improving the adaptability and scalability of lighting effect control.

[0055] In this embodiment, the lighting effect control method can be based on the EE (Electrical Electron) architecture, platform lighting effect control, and move the lighting effect driver to the domain controller. Using standardized interfaces, a scalable, flexible and maintainable lighting effect control system can be built, so that light groups with different layouts can be driven and adapted adaptively. Users can customize lighting effects, application scenarios can be arranged, and the decoupling of lighting effect control software and hardware can be achieved, which is conducive to shortening the development cycle of lighting effect control driver software and reducing the difficulty of maintaining lighting effect control.

[0056] The following will describe in detail the steps of the lamp group control method, as follows:

[0057] Before step 110, the method may include the step of creating a driver database. For example, before acquiring the target lighting effect data corresponding to the specified lighting effect mode from the driver database, the method may also include:

[0058] Based on at least two lighting effect modes and corresponding control parameters, a correspondence between the lighting effect mode and the lighting effect data is established to obtain the driving database, wherein the lighting effect data includes the control parameters corresponding to the corresponding lighting effect mode, and the driving database includes the target lighting effect data corresponding to the specified lighting effect mode.

[0059] In this embodiment, in the driving database, the lighting effect mode may include a dynamic lighting effect mode and a static lighting effect mode. The dynamic lighting effect mode may include but is not limited to a flowing water mode, a meteor mode, and a breathing mode. The control parameters may include, but are not limited to, the location information of the light zone, the flashing frequency, the brightness duty cycle, and the gradient parameters. Among them, the gradient parameters may include but are not limited to the gradient color type, the gradient frequency, and the like.

[0060] The flow mode can be subdivided according to the direction of the flow, such as, for example, the flow mode can include a left flow mode, a right flow mode, an upper flow mode, a lower flow mode, a dispersed flow mode and a converged flow mode.

[0061] Similarly, the meteor mode may include a left meteor mode, a right meteor mode, an upper meteor mode, a lower meteor mode, a dispersed meteor mode, and a converged meteor mode.

[0062] The static lighting effect mode may be a lighting effect mode that emits light with a specified light color and / or a specified light brightness. Both the specified light color and the specified light brightness may be flexibly set according to actual conditions.

[0063] In breathing mode, the breathing frequency and light color of the light group can be flexibly set according to actual conditions.

[0064] In this embodiment, the lighting effect data may be a two-dimensional array. The two-dimensional array may be represented as: FLPosn_Mode1[z][n] = {{c1, d1, e1, ...}, ..., {c z ,d z ,e z ,…}}, where z refers to the number of light strings that are lit, n refers to the number of parameters corresponding to a single light string, {c z ,d z ,e z ,…} represents the parameters corresponding to the zth light string, and the number of parameters is n. For example, c z ,d z ,e z Can represent different parameters, for example, c z Indicates the starting position of the lamp bead in the zth lamp string, d z Indicates the length of the zth light string (referring to the number of light zones in the light string), e z Indicates the lighting effect mode of the zth light string.

[0065] As an example, for the meteor mode, the lighting effect array is set to FLPosn_Mode1[1][3]={{10,24,3}}, where [1] represents the number of light strings to be lit is 1, and [3] represents that this light string contains three parameters, namely 10, 24, and 3. In {10,24,3}, 10 can represent that the starting bit (position) of the light string is 10, 24 represents the total bit length (referring to the number of light zones) is 24, and the corresponding control is P10_L to P32_L; 3 can represent the left meteor mode, which can be used to select the public function corresponding to the left meteor to calculate the lighting time and extinguishing time of the corresponding light zone. The lighting effect array can also include other parameters, such as the meteor length Meteorbit, which can be flexibly set according to the actual situation. For example, if Meteorbit is 4, it means that the number of lamp beads that are lit at the same time is 4.

[0066] Engineers can establish the correspondence between lighting effect modes and lighting effect arrays through various lighting effect modes and corresponding control parameters, thereby obtaining a driver database that supports multiple lighting effect mode drivers, thereby increasing the scalability and adaptability of lighting effect control.

[0067] After the driver database is established, engineers can adjust the control parameters in the lighting effect data according to the different layouts of the lighting groups and the desired lighting effect scheme (the lighting effect scheme may include parameters such as light brightness, lighting effect mode, and flashing frequency) to update the driver database. For example, between the step of establishing a correspondence between the lighting effect mode and the lighting effect data based on at least two lighting effect modes and corresponding control parameters, and the step of obtaining the target lighting effect data corresponding to the specified lighting effect mode from the driver database, the method may further include:

[0068] Based on the received modification instruction, the control parameters in the lighting effect data corresponding to the modification instruction are adjusted, and the corresponding relationship between the lighting effect mode and the lighting effect data is updated to obtain an updated driving database.

[0069] The control parameters that can be modified can be the position, flickering frequency, light brightness and other parameters of any light zone. In this way, when light groups with different layouts use the same lighting effect mode, users can only modify the position, flickering frequency, light brightness and other parameters of the light zone to achieve driver adaptation without redesigning the driver software, which is conducive to improving the development efficiency of the driver software and reducing development costs. In addition, the lighting effect can be personalized according to different users.

[0070] In step 110, the control instruction may carry identification information (recorded as the first identification) indicating the specified lighting effect mode. Since the driving database pre-stores lighting effect data corresponding to various lighting effect modes, after parsing the control instruction and obtaining the first identification, the lighting effect data with the same first identification can be found from the driving database as the target lighting effect data.

[0071] The specified lighting effect mode is the aforementioned dynamic lighting effect mode or static lighting effect mode. The dynamic lighting effect mode may be, but is not limited to, a flowing water mode, a shooting star mode, and a breathing mode. The static lighting effect mode may be a lighting effect mode that emits light with a specified light color and / or a specified light brightness.

[0072] In this embodiment, if the application scenario is a vehicle, the control command can be issued by a smart phone bound to the vehicle, or triggered by the user operating the vehicle's central control display screen, or triggered by other means. There is no specific restriction on the way the control command is generated here.

[0073] In this embodiment, the target lighting effect data may be a two-dimensional lighting effect array, which may be used as the target lighting effect array. In step 120, based on the control instruction and the target lighting effect data, determining the target light area to be controlled in the light group and the control parameters corresponding to the target light area may include:

[0074] According to the identification information (recorded as the second identification) representing the light zone to be controlled carried in the control instruction, determining the light zone in the light group that matches the identification information as the target light zone;

[0075] Read each parameter from the target lighting effect array according to a pre-established correspondence between the position of the parameter in the lighting effect array and the parameter type, and determine the parameter type of each parameter according to the position of each parameter in the target lighting effect array, wherein the target lighting effect array includes the position information of the target light area, the flashing frequency, the brightness duty cycle, and one of the gradient parameters;

[0076] Based on the position information of the lamp beads, the lighting time and the off time of the lamp beads in the target lamp area are determined using a function corresponding to the lighting effect mode, and the lighting time, the off time, each parameter and the parameter type of each parameter are used as control parameters corresponding to the target lamp area.

[0077] Understandably, some relatively basic parameters can be recorded in the lighting effect array, such as fixed data such as the location information of the light zone and the lighting effect mode. The lighting time and the extinguishing time of the light zone as variable data can be calculated by the function corresponding to the location information of the light zone in the lighting effect array and the corresponding lighting effect mode.

[0078] In this embodiment, the target light area is the area in the light group that needs to be controlled. The lights in the uncontrolled area of ​​the light group do not need to be lit. The corresponding relationship between the position of the parameter in the light effect array and the parameter type can be flexibly set according to the actual situation, and is not specifically limited here.

[0079] In the control command, the area LampArea of ​​the domain control can be carried. For example, define the area number LampArea of ​​the left front position light of the vehicle as 2 (that is, the second identifier), please refer to Figure 3 The left front position light includes 24 light zones, namely P10L-P33L, representing bits 10 to 33 of the left front position light, and each light zone has two lamp beads. In this way, the second identifier in the control instruction can be used to identify the area to be controlled, and all the light zones in the area are target light zones.

[0080] In this embodiment, the lighting time and the extinguishing time of the target light zone can be calculated by using different public functions according to different lighting effect modes.

[0081] As an example, when the lighting effect mode is the left meteor mode, the common function of the lighting time of the target light zone can be:

[0082] Start_time=Mid_TimeArry[LampArea-1][i-1]+Tasktime+FlowFrq

[0083] In the formula, Start_time refers to the lighting time, or the starting time;

[0084] If the target lamp area is not the first lamp area in the lighting effect control process, Mid_TimeArry[LampArea-1][i-1] refers to the middle time of the previous lamp area; if the target lamp area is the first lamp area in the lighting effect control process, Mid_TimeArry[LampArea-1][i-1] can be the time when the control command is received;

[0085] LampArea refers to the area in the lamp group, and i refers to the current number of lamp areas;

[0086] Tasktime refers to the running time of the software cycle, for example, 20 milliseconds. The software corresponds to the lighting effect control method.

[0087] FlowFrq refers to the interval frequency or interval duration of meteor slides.

[0088] The common function of the extinction time can be:

[0089] Stop_time=Start_time+(Meteorbit-1)*(Tasktime+FlowFrq)+(FlowSize)*(Tasktime+FlowFrq)

[0090] In the formula, Stop_time refers to the extinguishing time, or the stopping time;

[0091] Start_time refers to the lighting time;

[0092] Meteorbit refers to the length of a meteor, which is the number of lamp beads lit by a single meteor;

[0093] FlowSize refers to the length of the current light string in the light group.

[0094] The calculation function of the intermediate time can be:

[0095] Mid_time=Start_time+(Meteorbit-1)*(Tasktime+FlowFrq)+(FlowSize-Meteorbit)*(Tasktime+FlowFrq)

[0096] The middle time Mid_time can be used to calculate the lighting start time of the next controlled lamp area, and can be used as Mid_TimeArry[LampArea-1][i-1].

[0097] Each of the light zones is associated with a corresponding control channel in an IC (Integrated Circuit) driver. In step 130, based on the control parameters, controlling the target light zone to operate in the specified lighting effect mode may include:

[0098] Based on the lighting time and the extinguishing time, or based on the lighting time, the extinguishing time and each parameter, all the lamp beads in the target light area are controlled to operate through the corresponding control channel in the integrated circuit driver so that the target light area emits light in the specified lighting effect mode, wherein each parameter includes one of a flashing frequency, a brightness duty cycle and a gradient parameter.

[0099] For example, the light zones in the light group are divided into 1 to 20, and each zone corresponds to a group of LED lights. Using the function "LgithSet_Device", the domain controller passes parameters such as the light area (LightArea), the light zone / lamp bead position (Posn) to be turned on, the lighting time, the off time and the duty cycle (DutyRatio) to the IC driver (that is, the driver chip). The driver chip parses these parameters and uses the corresponding control channel to light up the lamp beads in the corresponding light zone. In this way, the decoupling of software and hardware is conducive to improving the flexibility and scalability of the method, and is convenient for future functional expansion and optimization. Among them, the LgithSet_Device function is used to transmit the control parameters calculated in the domain controller to the IC driver.

[0100] Please refer to Figures 2 to 4 ,This method is based on EE architecture and can directly drive the IC driver chip (i.e., IC driver). The implementation process of the method involves application layer software, complex driver and underlying chip driver, such as Figure 2 As shown. The complex driver includes the driver database and other parameters or functions related to the driver. In order to meet the needs of platform software, the lighting effect array, meteor length Meteorbit, interval frequency and other parameters are set as configurable items or settable items open to the outside world. Different configurations meet different application scenarios or vehicle model adaptation. In order to achieve software and hardware decoupling and adapt to the lighting control of different models, the following strategies are adopted:

[0101] Modular design: modularize the functions of the lighting effect modes, simplify the independent implementation of different lighting effect modes (such as breathing mode, up and down, left and right water flow mode, etc.). Each lighting effect mode can be called through a unified interface.

[0102] Configuration file: defines a standard configuration file format, including the lighting parameters of each vehicle model (such as lamp bead position, lighting effect type, etc.). The data format of the configuration file can be a two-dimensional array, that is, a lighting effect array. By modifying the lighting effect array, the hardware layout of different vehicle models can be adapted.

[0103] Position mapping: Using the mapping function, the incoming light zone / light string / area position (Posn) can be mapped to the light parameters in the lighting effect array, and the mapping function can be used to handle the position changes of lamp beads for different models.

[0104] Dynamic effect support: Provides user customization function for dynamic lighting effects, allowing users to define various combinations of lighting effects, such as flashing frequency, breathing frequency, gradient color, etc., and dynamically load user-defined lighting effects through standard interface parameter transmission and configuration files.

[0105] Unified interface: Provides a unified interface for static and dynamic lighting effects. Static lighting effects directly transmit application layer data, while dynamic lighting effects can calculate the positions of the remaining light zones / lamp beads based on the initial position and total length of the first light zone / lamp bead in the controlled light group.

[0106] In complex dynamic driving, the public functions of the corresponding lighting effect modes are used to calculate the corresponding control parameters of the lamp beads to ensure that the lighting effects of the lamp groups in different car models are consistent under the same lighting effect mode.

[0107] Through the above strategy, it is possible to ensure flexible adaptation of lighting effects between different models while reducing the coupling between software and hardware.

[0108] In addition, in the electronic control system of the vehicle, both the application layer and the basic software layer use standardized interfaces, which is conducive to enhancing the operability of the system, improving development efficiency, reducing integration complexity, and improving the maintainability and scalability of the system. In the lighting control system, the control is mainly divided into three levels: application software, complex driver and underlying software driver chip. The realization of lighting effects is mainly completed in the complex driver. The complex driver receives instructions from the application layer through the defined standardized interface, including instruction parameters such as lighting control mode, flashing frequency, position of driving lamp beads, brightness duty cycle, breathing mode parameters and gradual light and fade time. For the lower layer, the complex driver passes the instructions to the driver layer through the Set interface to directly control the IC driver chip. For example, the light zones in the light group are divided into 1 to 20, and each light zone corresponds to a group of LED lights. Using the function "LightSetDevice", the domain controller passes parameters such as the light area (LightArea), the light zone / lamp bead position (Posn) to be turned on, the lighting time, the extinguishing time and the duty cycle (DutyRatio) to the IC driver. The driver chip parses these parameters and uses the corresponding control channel (such as Figure 3 In this way, the software and hardware are decoupled, which is conducive to improving the flexibility and scalability of the method and facilitating future functional expansion and optimization.

[0109] The separation of lighting effect control and hardware configuration allows the adaptation of lighting effects to be completed only by modifying the configuration file without changing the underlying code, thereby improving the maintainability and scalability of the system.

[0110] For static lighting effects, the lamp bead position information sent by the application layer can be directly transmitted. That is, after the controlled area is determined in the light group, all the lamp beads in the controlled area can be directly used as control objects without calculating the controlled lamp beads one by one.

[0111] Dynamic lighting effects need to support higher flexibility to allow for custom functions. The calculation of the lamp bead position will be completed in the driver code, and the configuration file allows the modification of the lighting effect's starting position, total length, and effect type, which are written into the lighting effect array. This centralized management method allows lighting effect parameters such as the lighting effect array and meteor length (Meteabit) to be easily adjusted, avoiding the complexity of in-depth code modification.

[0112] For example, the lighting area (LightATRa) can be split into continuous LED strings according to the configuration file, including the start position, total length and control mode. The start and end time of the light string is automatically calculated through the general function, and the lighting effect is dynamically realized, which simplifies the development process. This design not only improves development efficiency, but also enables maintenance personnel to quickly get started and flexibly adjust parameters to achieve the desired effect.

[0113] The direct drive mode of the EE architecture has the advantages of fast response speed, simplified hardware design, and high reliability. By calculating the control parameters on the domain controller, parameters such as the position of the lamp beads (Posn) and the lighting time can be quickly obtained, and these parameters can be directly written into the driver chip. Subsequently, the driver chip is called to transmit the corresponding information and quickly drive the corresponding channel to complete the lighting effect display.

[0114] The above solution can meet the platform requirements of lighting effect driving. Different mapping relationships or different light groups, different car models, only need to modify the lighting effect array in the configuration file to complete the adaptation, without modifying the complex driver-related code, can realize the platformization and standardization of lighting effect control, shorten the development cycle of various types of car lighting products, and reduce the cost of car lighting development and management.

[0115] As an example, see Figure 3 , if the light group is the left front position light of the vehicle, when the lighting effect mode is specified as meteor mode, the area number LampArea of ​​the left position light is defined as 2, which can include light areas P10_L-P33_L, representing bits 10 to 33 of the left position light. The lamp beads mapped to the left position light area are numbered 1-48. Each control channel of each IC driver corresponds to a light area P, and each light area includes two lamp beads, such as Figure 3 The shooting star can light up all left front position lamps in the following ways:

[0116] The application layer sends a control command to light up in meteor mode, set the interval frequency to 20ms, and the lighting effect array is FLPosn_Mode1[1][3]={{10,24,3}}, 10 represents the starting bit is 10, 24 represents the total bit length is 24, and the corresponding control is P10_L to P33_L. The parameter 3 in {10,24,3} represents the left meteor effect, and the left meteor public function is selected to implement it. The meteor length Meteorbit can be 4, which means that the number of lamp beads lit at the same time is 4. In complex drivers, the relevant control parameters (such as the starting bit) are passed into the public function, in which the Start_time, Stop_time, and Mid_time of each bit lighting time are automatically calculated. During the start and stop time, the left meteor function is called periodically. In each cycle of the left meteor function, bit10 to bit13 are lit in sequence, and then the values ​​of these four bits are moved to the left until bit33 changes from 1 to 0 (indicating that the lamp beads in the lamp area where bit33 is located have changed from emitting to extinguishing). The bit value after each cycle is written into CddLampIDbit (CddLampIDbit is a cache space that can store the value of the lamp area bit), and the LgithSet_Device function is called to pass the parameters of the light area 2, the position of the lamp beads to be turned on CddLampIDbit, and the duty cycle to the chip driver function. According to the datasheet of the driver chip, the underlying code of the UART (Universal Asynchronous Receiver / Transmitter) communication protocol is completed to realize the control of the LED lights of the corresponding channel. That is, by controlling the channel, the corresponding bit is controlled to turn on and off, and the light effect of the left meteor is realized.

[0117] In this embodiment, the control bit position may vary due to the different number and position of the lamp beads in the lamp group, or the different lighting effects expected to be presented. In order to adapt to this variability, the control parameters can be changed through external calls or configuration files. That is, the control parameters can be adjusted by modifying the lighting effect array.

[0118] For example, see Figure 4 The rear position lamp of the vehicle is a C-shaped lamp, and its lamp area mapping and position distribution are as follows: Figure 4As shown, define the left position light area number LampArea as 3. The convergence pipeline is to light up each bit in sequence from both ends to the middle. The tail light of this shape first lights up bit14-bit10, then lights up bit6-bit9, and finally lights up bit15-bit32. The same is true for the right position light. According to the mapping of the position light area, set the lighting effect array to RLPosn_Mode1[3][3]={{14,5,2},{6,4,1},{15,18,1}}, and set the number of left position light strings z of a C-shaped tail light to 3. The last parameter of each string of lights represents the function of the shift operation. Parameter 1 in {15,18,1} is to use the left pipeline function for shift operation, and parameter 2 in {14,5,2} is to select the right pipeline function for shift operation. The time calculation of each string of lights is performed in the public function. The flow time is divided into the lighting time Start_time and the stop time Stop_time.

[0119] Start time Start_time = StopTimeArry[LampArea-1][i-1]+Tasktime+FlowFrq;

[0120] Among them, StopTimeArry[LampArea-1][i-1] can refer to the time when the control command is received, or the time when the last lamp area is turned off;

[0121] Stop time Stop_time = Start_time + (FlowSize-1)*Tasktime + (FlowSize-1)*FlowFrq.

[0122] Each string of lights calls the flow function to perform shift operations at the start time and stop time, and stores the results of each string of lights in the parameter CddLampIDbit by OR operation. The parameters are also passed to the driver chip for channel driving to display the flow effect. The application layer simultaneously sends the left flow control of the left rear position light and the left flow control of the right rear position light, which can achieve the convergent flow effect of the entire taillight.

[0123] Each lighting effect corresponds to a set of lighting effect arrays. In this way, even if the left and right flow reference of the overall lighting effect is changed, there is no need to write new code to implement it and modify the lighting effect array in the configuration file for adaptation. Therefore, based on the above design, no matter it is different car models, different driver chips, different required lighting effect definitions, or different lighting hardware, they can all be adapted using the method of this application. That is, by moving the driver up to the domain controller, differentiated driver adaptation can be achieved for different platform models.
