[0065] S2, receiving an instrument panel light guide request sent by a signal sending port, and performing request analysis on the instrument panel light guide request to obtain a to-be-lighted area and an initial area light source configuration.

[0066] It can be understood that the signal sending port refers to a communication interface capable of sending instructions or requests to the instrument panel signal receiving port, such as a mobile phone App or a vehicle-mounted light perception system. It should be noted that the connection mode of the signal sending port and the instrument panel signal receiving port can be wired or wireless, for example, the mobile phone App can send a "start welcome light" instruction to the instrument panel signal receiving port of the instrument in a wireless manner. The instrument panel light guide request refers to a complete data packet carrying "function data to be lighted" information, for example, in a vehicle instrument panel, the instrument panel light guide request can be a complete data packet carrying "vehicle speed data to be lighted". The to-be-lighted area refers to a specific geometric area on the multifunctional instrument panel that needs to be illuminated by backlight, for example, a speed digital display area in a vehicle multifunctional instrument panel. The initial area light source configuration is a backlight parameter set of the default to-be-lighted area of the multifunctional instrument panel, for example, the initial area light source configuration of the speed data area in the multifunctional instrument panel can be 30% white light without animation.

[0067] It can be understood that in the embodiments of the present application, the dashboard signal receiving port can perform event listening on external trigger events. When an external trigger event occurs outside the multifunctional dashboard, the external trigger event can generate an original trigger signal and activate the signal sending port. Further, the signal sending port can send a dashboard light guide request to the dashboard signal receiving port according to the original trigger signal.

[0068] It can be understood that when the dashboard signal receiving port receives the dashboard light guide request sent by the signal sending port, by analyzing the dashboard light guide request, the area that needs to be light guided and the initial light source configuration information of the area, i.e., the to-be-light-guided area and the initial area light source configuration, can be determined.

[0069] In detail, the request analysis on the dashboard light guide request to obtain the to-be-light-guided area and the initial area light source configuration comprises:

[0070] information extraction on the dashboard light guide request to obtain dashboard display information;

[0071] dashboard display area positioning on the dashboard display information to obtain the to-be-light-guided area;

[0072] light source parameter matching based on the preset area light source configuration parameter and the to-be-light-guided area to obtain the initial area light source configuration.

[0073] It can be understood that the dashboard display information refers to the data in the dashboard light guide request that needs to be displayed in the multifunctional dashboard, for example, vehicle speed, time, remaining fuel quantity, etc. The preset area light source configuration parameter refers to the initial light source configuration parameter of each area that is preset, wherein the initial light source configuration parameter includes brightness, color, color temperature, etc.

[0074] It can be understood that in the embodiments of the present application, the dashboard signal receiving port can split the dashboard light guide request into a request header, a request body and other fields, and then perform information positioning on the fields containing main information to obtain the field position that needs to be information extracted. Further, information reading is performed on the field position to obtain the dashboard display information. Then, semantic understanding is performed on the dashboard display information to determine the functional data that needs to be displayed in the multifunctional dashboard, and the dashboard area in the multifunctional dashboard where the functional data is displayed, i.e., the to-be-light-guided area, is queried. Finally, the preset area light source configuration parameter is traversed according to the to-be-light-guided area to determine the default light source parameter of the to-be-light-guided area, i.e., the initial area light source configuration.

[0075] It can be understood that the embodiments of the present application can extract information from the instrument panel light guide request, and can determine the information to be displayed by the multifunctional instrument panel. Secondly, the instrument panel display information is mapped to the physical coordinates, and the to-be-guided area can be accurately circled, which enhances the accuracy of light spot positioning. Finally, according to the preset area light source configuration parameters, the brightness, color temperature, animation rhythm and other attributes of the to-be-guided area are quickly matched, so that the initial area light source configuration of the to-be-guided area corresponds to the hardware capability one by one, which avoids excessive or insufficient driving, and improves the light guiding accuracy of the multifunctional instrument display.

[0076] S3, based on the instrument panel light guide request, the multifunctional instrument panel is environment light source perception, and the environment light source intensity is obtained.

[0077] It can be understood that the environment light source intensity refers to the illumination intensity information of the environment around the multifunctional instrument panel.

[0078] It can be understood that the embodiments of the present application can capture the illumination intensity of the environment around the multifunctional instrument panel through the illumination intensity sensor, so as to obtain the environment light source intensity.

[0079] In detail, based on the instrument panel light guide request, the multifunctional instrument panel is environment light source perception, and the environment light source intensity is obtained, including:

[0080] Based on the instrument panel light guide request, the multifunctional instrument panel is environment light signal capture, and the original light signal is obtained;

[0081] The original light signal is photoelectric converted to obtain an analog voltage value;

[0082] Based on the analog voltage value, the light intensity is mapped to obtain the environment light source intensity.

[0083] It can be understood that the original light signal refers to the instantaneous value of the photocurrent or the photovoltage of the natural light or artificial light propagating in the space around the multifunctional instrument panel. The analog voltage value refers to the voltage waveform representation of the continuous time and continuous amplitude of the original light signal.

[0084] It can be understood that the embodiment of the application can converge the natural light or artificial light propagating in the space around the multifunctional instrument panel into the effective light-sensing surface of the sensing chip in the light intensity sensor through the optical window and the microlens array in the light intensity sensor, so as to obtain the original light signal. Secondly, the captured light energy in the original light signal can be converted into a measurable electrical signal, that is, an analog voltage value, by using the semiconductor photoelectric effect. Finally, by performing analog-digital conversion on the analog voltage value, a digital sampling value is obtained. By filtering and denoising the digital sampling value, a denoised sampling value can be obtained. Further, by performing linear calibration on the denoised sampling value, a calibrated brightness value can be obtained. By performing linear or nonlinear mapping on the calibrated brightness value, the light intensity around the multifunctional instrument panel, that is, the intensity of the ambient light source, can be obtained.

[0085] It can be understood that the embodiment of the application can capture the ambient light signal of the multifunctional instrument panel based on the instrument panel light guiding request to obtain the original light signal, which can ensure the real-time performance of light detection. Secondly, the original light signal can be converted into an analog voltage value, which can improve the readability and stability of the original light signal. Finally, by mapping the analog voltage value to the light intensity space, the conversion from the analog voltage value to the intensity of the ambient light source can be realized, which can improve the quantitative perception of the external light of the multifunctional instrument panel.

[0086] S4, based on the instrument panel light guiding request, performing carrier state sensing on the multifunctional instrument panel to obtain carrier state information.

[0087] It can be understood that the carrier state information refers to the carrier speed, carrier acceleration and other information of the multifunctional instrument panel.

[0088] It can be understood that the embodiment of the application can record the speed, acceleration and other data of the carrier of the multifunctional instrument panel according to the instrument panel light guiding request while obtaining the intensity of the ambient light source, so as to obtain the carrier state information.

[0089] S5, determining a carrier running mode based on the intensity of the ambient light source and the carrier state information.

[0090] It can be understood that the carrier running mode is determined by the running environment of the carrier of the multifunctional instrument panel. For example, when the running environment of the carrier of the multifunctional instrument panel is a tunnel, the carrier running mode can be a tunnel driving mode.

[0091] In detail, the determination of the carrier running mode based on the intensity of the ambient light source and the carrier state information comprises:

[0092] grading quantization of the intensity of the ambient light source to obtain a light intensity level;

[0093] based on the carrier state information, performing state label matching to obtain a target state label;

[0094] Based on the illumination intensity level and the target state label, a rule base retrieval is performed to obtain a carrier running mode.

[0095] It can be understood that the illumination intensity level refers to a discrete gear obtained after quantization of the ambient light source intensity level, for example, multiple gears such as extremely dark, dark, medium, bright, and extremely bright. The target state label refers to a discrete gear set obtained after quantization of each state information level in the carrier state information, for example, the speed information can be quantized into multiple gears such as extremely fast, fast, medium, slow, and extremely slow, and the acceleration information can be quantized into multiple gears such as extremely large, large, medium, small, and extremely small. When the carrier state information indicates that the speed information is slow and the acceleration information is extremely small, the target state label can be “slow and uniform speed”.

[0096] It can be understood that in the embodiments of the present application, the ambient light source intensity can be quantized into a corresponding illumination intensity level according to a pre-set mapping rule of the light source intensity and the light intensity level, for example, when the ambient light source intensity is 0-50 lx, the illumination intensity level is set to “extremely dark”, when the ambient light source intensity is 50-500 lx, the illumination intensity level is set to “dark”, when the ambient light source intensity is 500-5000 lx, the illumination intensity level is set to “medium”, when the ambient light source intensity is 5000-25000 lx, the illumination intensity level is set to “bright”, and when the ambient light source intensity is greater than 25000 lx, the illumination intensity level is set to “extremely bright”.

[0097] Secondly, in the embodiments of the present application, the carrier state information can also be quantized into a corresponding state level according to a pre-set mapping rule of the carrier state information and the state level, and a plurality of state levels can be collected to obtain a target state label.

[0098] Finally, the running mode corresponding to the above-mentioned illumination intensity level and the target state label is retrieved from the pre-constructed rule base, so as to obtain the carrier running mode, for example, when the illumination intensity level is dark and the target state label includes “straight driving”, “low speed”, and “uniform speed”, it can be known through rule base retrieval that the carrier is in tunnel driving, and therefore the carrier running mode can be a tunnel running mode.

[0099] It can be understood that the embodiments of the present application quantize the continuous ambient light source intensity into discrete levels, so that the multifunctional instrument panel can quickly understand the external illumination intensity. Secondly, the carrier state information is used to complete the state label matching, and the carrier state information is mapped into a target state label, which can ensure that the light guide configuration of the multifunctional instrument panel corresponds to the driving scene of the carrier in real time. Finally, the rule base pre-constructed according to the illumination intensity level and the target state label is queried, and the carrier running mode can be obtained, which facilitates the multifunctional instrument panel to make light guide decisions, thereby improving the light guide efficiency and accuracy of the multifunctional instrument panel.

[0100] S6, based on the carrier operation mode, performing configuration adjustment on the initial regional light source configuration to obtain a target regional light source configuration.

[0101] It can be understood that the target regional light source configuration refers to the real light source configuration information of the to-be-guided light region after environmental correction.

[0102] It can be understood that the target regional light source configuration is obtained by performing configuration adjustment on the initial regional light source configuration based on the carrier operation mode, including:

[0103] performing light brightness configuration prediction on the to-be-guided light region based on the carrier operation mode to obtain a regional light brightness configuration;

[0104] extracting light brightness configuration information from the initial regional light source configuration to obtain an initial regional light brightness configuration;

[0105] performing brightness parameter adjustment on the initial regional light source configuration based on the regional light brightness configuration and the initial regional light brightness configuration to obtain the target regional light source configuration.

[0106] It can be understood that the regional light brightness configuration refers to a combination of light brightness parameters such as brightness, color temperature, and color saturation of the to-be-guided light region on the multifunctional instrument panel. The initial regional light brightness configuration refers to the default brightness, color temperature, and other light brightness parameters of the to-be-guided light region before considering the surrounding environmental factors of the multifunctional instrument panel.

[0107] It can be understood that in the embodiments of the present application, the historical light brightness parameters corresponding to the carrier operation mode of the multifunctional instrument panel can be determined according to historical experience, that is, the regional light brightness configuration, and then the initial regional light brightness configuration in the initial regional light source configuration can be adjusted according to the regional light brightness configuration, that is, the complete target regional light source configuration can be obtained. For example, when the carrier operation mode of the multifunctional instrument panel is a tunnel operation mode, according to the historical data recorded by the multifunctional instrument panel, it can be known that the multifunctional instrument panel needs strong light source brightness, that is, the regional light brightness configuration is a high-brightness parameter configuration.

[0108] It can be understood that according to the carrier operation mode, the historical light brightness configuration of the to-be-guided light region is queried, the ideal brightness and color temperature of the to-be-guided light region in the carrier operation mode scenario can be quickly locked, secondly, the default parameters related to light brightness are extracted from the initial regional light source configuration to form the initial regional light brightness configuration, which is convenient for comparison with the regional light brightness configuration, and finally, based on the regional light brightness configuration and the initial regional light brightness configuration, the brightness parameter adjustment is performed on the initial regional light source configuration, so that the obtained target regional light source configuration not only meets the user's demand, but also meets the current environment of the carrier, thereby the multifunctional instrument panel not only saves energy consumption, but also maintains readability.

[0109] The light brightness configuration of the region is obtained by predicting the light brightness configuration of the region to be guided light based on the carrier operation mode.

[0110] The historical light guiding data is obtained.

[0111] The historical light source configuration matching item is obtained by matching the carrier operation mode, the region to be guided light and the historical light guiding data.

[0112] The light brightness configuration of the region is obtained by extracting the light brightness from the historical light source configuration matching item.

[0113] It can be understood that the historical light guiding data refers to the light brightness parameter information of each region in various environments stored in the past year or month before the current time node. The historical light source configuration matching item refers to the light brightness parameter information of the region to be guided light in the environment represented by the carrier operation mode.

[0114] It can be understood that before the embodiment of the present application, the multifunctional instrument panel will record the light guiding data of itself to form light guiding storage data. It needs to be known that the light guiding data recorded by the multifunctional instrument panel includes the region information of the multifunctional instrument panel, the carrier operation mode and the light source configuration parameters of each region. Therefore, the historical light guiding data can be obtained by querying the database storing the light guiding storage data. Secondly, the corresponding information of the carrier operation mode of the multifunctional instrument panel at the current time node, the region to be guided light and the historical light guiding data is matched, and when the carrier operation mode of the multifunctional instrument panel at the current time node, the region to be guided light and the historical light guiding data are matched successfully, the light source configuration parameters in the matched historical light guiding data are taken as the historical light source configuration matching item. If the carrier operation mode of the multifunctional instrument panel at the current time node, the region to be guided light cannot find the same data item in the historical light guiding data, it is not necessary to adjust the initial region light source configuration. Finally, when the carrier operation mode of the multifunctional instrument panel at the current time node, the region to be guided light and the historical light guiding data are matched successfully, the data related to the light brightness parameter in the historical light source configuration matching item is read, and the light brightness configuration of the region can be obtained.

[0115] The embodiment of the application can accurately match the most suitable light source configuration of the to-be-guided light region in the carrier running mode, that is, the historical light source configuration matching item, by obtaining historical light guide data, and after obtaining the historical light guide data, performing mode matching on the carrier running mode and the historical carrier running mode in the historical light guide data, and performing data matching on the to-be-guided light region and the historical light guide region in the historical light guide data, thereby reducing the light source adjustment of the to-be-guided light region and improving the display accuracy of the multifunctional instrument. Further, the historical light source configuration matching item is subjected to light extraction to obtain a regional light configuration, so that the optimized light parameters under similar conditions can be quickly and accurately applied to the to-be-guided light region before application, thereby enhancing the display efficiency of the multifunctional instrument panel.

[0116] S7, adjusting the light source of the to-be-guided light region based on the backlight array information and the target region light source configuration to obtain a target guided light region.

[0117] It can be understood that the target guided light region refers to a uniform and required light spot region actually presented on the multifunctional instrument panel after the light source adjustment.

[0118] In detail, the adjusting the light source of the to-be-guided light region based on the backlight array information and the target region light source configuration to obtain a target guided light region comprises:

[0119] performing region analysis on the to-be-guided light region to obtain a region function;

[0120] performing data capture based on the region function to obtain original function data;

[0121] performing light guide processing on the to-be-guided light region based on the backlight array information, the target region light source configuration and the original function data to obtain a target guided light region.

[0122] It can be understood that the region function refers to the function represented by the data displayed by the to-be-guided light region. The original function data refers to the carrier data corresponding to the region function, for example, speed, acceleration, remaining oil quantity and the like.

[0123] It can be understood that in the embodiments of the present application, a correspondence table describing the function corresponding to each region is pre-stored, so that the region analysis of the to-be-guided light region can be realized by querying the correspondence table, the function corresponding to the to-be-guided light region is determined, and the region function is determined. Secondly, after the region function is determined, the data required by the region function is recorded, so that the data acquisition can be realized. For example, when the region function is a speed display function, the carrier speed data of the multifunctional instrument panel needs to be recorded to obtain the original function data. Finally, after the original function data to be displayed is determined, the light source data of the to-be-guided light region can be adjusted according to the backlight array information and the target region light source configuration, so that the light guiding of the to-be-guided light region is realized, and the target guided light region can be obtained.

[0124] It can be understood that the embodiments of the present application abstract the to-be-guided light region as a region function by region analysis of the to-be-guided light region, and then capture data according to the region function to obtain original function data, so that the region light guiding can determine the data to be displayed. Further, based on the backlight array information, the target region light source configuration and the original function data, the to-be-guided light region is guided to obtain the target guided light region, so that the light spots in the target guided light region are uniform and low in consumption, thereby improving the light guiding efficiency of the multifunctional instrument panel.

[0125] The method comprises:

[0126] Generating a region light guiding instruction based on the target region light source configuration, the to-be-guided light region and the original function data;

[0127] Reading the array state of the backlight array information to obtain a current light source capability table;

[0128] Based on the region light guiding instruction and the current light source capability table, the to-be-guided light region is regionally dimmed to obtain the target guided light region.

[0129] It can be understood that the region light guiding instruction is an instruction for controlling the light guiding effect of the to-be-guided light region. The current light source capability table is a table showing the capability of the backlight array, wherein the table records the performance of each light source in the backlight array under the current environmental conditions, such as maximum brightness, color temperature range, etc.

[0130] It can be understood that the embodiment of the application can generate the area light guide instruction for controlling the light guide effect of the area to be light guided by integrating the target area light source configuration, the area to be light guided and the original function data into a data packet. Secondly, the array state reading of the backlight array information can be realized by reading the current state of each light source in the backlight array information. The current state can be the performance of each light source in the backlight array under the current environmental condition. The performance of each light source in the backlight array under the current environmental condition, i.e. the current light source capability table, can be determined. Finally, the performance state of each light source in the backlight array can be adjusted according to the area light guide instruction and the performance of each light source under the current environmental condition shown in the current light source capability table, so as to realize the area dimming of the light guide area. It should be known that the target light guide area can be obtained when the area to be light guided can meet the requirements of the area light guide instruction.

[0131] It can be understood that the embodiment of the application generates accurate area light guide instructions according to the target area light source configuration, the area to be light guided and the original function data. The brightness, color temperature and animation rhythm information can be solidified into executable instruction streams, so as to ensure that the user demand and the display content correspond one by one. Secondly, the current light source capability table can be obtained by reading the array state in the backlight array information, so as to facilitate real-time mastering of the performance information of each light source in the backlight array. Therefore, the dimming range of each light source in the backlight array can be determined when the light guide is performed in the area to be light guided. Finally, the dimming capability of each light source in the backlight array is constrained by taking the area light guide instruction as a reference and taking the current light source capability table, and the area to be light guided is dimmed. The spot uniformity and power consumption of the target light guide area can be optimized at the same time, so as to improve the light guide efficiency of the multifunctional instrument panel.

[0132] It should be known that in order to protect the display effect of the target light guide area, the embodiment of the application can adjust the brightness of the target light guide area according to the spot uniformity of the target light guide area after obtaining the target light guide area, so as to make the display effect of the multifunctional instrument panel more prominent.

[0133] In detail, after the target light guide area is obtained by adjusting the light source of the area to be light guided based on the backlight array information and the target area light source configuration, the method further comprises:

[0134] Verifying the light path of the target light guide area to obtain the spot uniformity;

[0135] Based on the spot uniformity, error compensation is performed to obtain a corrected brightness instruction;

[0136] Based on the corrected brightness instruction, the brightness of the target light guide area is corrected to obtain a corrected light guide area.

[0137] It can be understood that the spot uniformity refers to the uniformity of the brightness distribution of the spot in the target light guide area. The corrected brightness instruction refers to an instruction for adjusting the brightness of the light source of the target light guide area. The corrected light guide area refers to the target light guide area whose spot uniformity is improved after brightness correction.

[0138] It can be understood that the embodiments of the present application can evaluate the spot uniformity of the target light guide area by calculating the light intensity difference between adjacent sensors, wherein the adjacent sensors refer to two sensors adjacent in position among the multiple sensors for detecting the light intensity distribution in the target light guide area. Further, if the light intensity difference is less than a preset threshold, it is considered that the spot uniformity is good and no brightness compensation is needed. If the light intensity difference is equal to or greater than the preset threshold, it is considered that the spot uniformity is poor and brightness compensation needs to be performed on the area where the adjacent sensors are located. Accordingly, a corrected brightness instruction can be generated. Finally, according to the corrected brightness instruction, brightness compensation can be achieved by adjusting the driving current or changing the pulse width modulation duty cycle of the area where the adjacent sensors are located, thereby achieving the effect of brightness correction and converting the target light guide area into a corrected light guide area.

[0139] It can be understood that the embodiments of the present application can verify the light path of the target light guide area by calculating the light intensity difference between adjacent sensors, and capture the spot uniformity of the target light guide area in real time, so that the multifunctional instrument panel can locate the place where the brightness difference exists in the target light guide area in real time. Further, a corrected brightness instruction can be generated according to the potential brightness difference in the target light guide area, and the target light guide area can be corrected in brightness according to the corrected brightness instruction to obtain a corrected light guide area, which can reduce the brightness difference of the corrected light guide area, thereby making the light guide effect of the multifunctional instrument panel more prominent.

[0140] The present application can comprehensively understand the layout and characteristics of the backlight array in the multifunctional instrument panel by acquiring the backlight array information of the multifunctional instrument panel. Further, the instrument panel signal receiving port can receive the instrument panel light guide request sent by the signal sending port, and analyze the instrument panel light guide request to accurately acquire the to-be-light-guided area and the initial light source configuration, thereby providing a basis for display adjustment of the multifunctional instrument panel. In addition, based on the instrument panel light guide request, the multifunctional instrument panel can perform ambient light source sensing to obtain the ambient light source intensity, and can perform carrier state sensing to obtain the carrier state information. Then, the carrier running mode can be determined according to the ambient light source intensity and the carrier state information, so that the multifunctional instrument panel can dynamically adjust the light source configuration according to the carrier running mode, thereby obtaining a target area light source configuration more suitable for the carrier running mode. Finally, based on the backlight array information and the target area light source configuration, the light source of the to-be-light-guided area can be adjusted to achieve uniform and efficient target light guide effect, thereby improving the light guide accuracy of the multifunctional instrument panel and improving the user experience.
