[0031] See also Figure 1 , Figure 1 A flowchart of a control method for a lighting simulation system in an intelligent cockpit provided by an embodiment of the present invention; Figure 2Specifically, a control method for a lighting simulation system in an intelligent cockpit is applied to a car; the lighting simulation system 100 includes: a vehicle model 10, a lighting device 30, a sensing device, and a plurality of adjustment devices arranged in the vehicle model; the control method includes: S1: Get simulated lighting information; S2: Obtain the user's driving habits; S3: Setting up a lighting simulation environment according to the simulated lighting information; S4: controlling the lighting device to output lighting to the vehicle model according to the simulated lighting information; S5: Obtaining received light information of the sensing device; S6: judging whether the lighting simulation environment conforms to the user's driving habits according to the received lighting information; S61: If not, the control regulating device executes the first processing strategy; S62: If yes, the control regulating device performs a cyclic detection on the driving environment.

[0032] Preferably, the driving habits include the lighting brightness of the cab.

[0033] Preferably, the first processing strategy includes controlling the regulating device to adjust the feedback light of the regulating lamp group in the cab.

[0034] In combination with actual usage, first, the light information that needs to be simulated is collected, and a lighting simulation environment is set up based on the simulated light information to achieve a high degree of restoration of the simulated scene; then the user's driving habits are obtained, for example, whether sunglasses are worn during driving, whether a sun visor is needed in a strong light environment, etc.; then, according to the lighting information that needs to be simulated, the lighting device 30 is controlled to output light to the vehicle model 10, and the lighting information received by the sensing device located on the vehicle model 10 is used to determine whether the current lighting simulation environment meets the user's driving environment. If it does not meet the requirements, the adjustment device is controlled to make corresponding adjustments to the driving environment.

[0035] Further, obtain simulated lighting information, including: Get the user's driving itinerary; Get weather information during your driving trip; According to the driving itinerary and weather information, the external light information in the first time period in the future is predicted; Generate simulated lighting information based on external light information.

[0036] Preferably, the driving itinerary includes the destination of the current itinerary, the origin of the current itinerary, and the driving road conditions and driving terrain between the origin and the destination.

[0037] Specifically, the user's driving itinerary is used as the background for collecting simulated lighting information; weather information is obtained based on the user's starting point and destination, and the external light information during driving is predicted based on the road conditions and terrain between the starting point and the destination. The prediction results are used as the simulated lighting information in this environment.

[0038] Furthermore, the lighting simulation system 100 further includes: a guide rail 20, which is arranged around the vehicle model 10; and a lighting simulation environment is set up according to the simulated lighting information, including: Analyze the simulated lighting information to obtain a first parameter, wherein the first parameter includes: light intensity, light irradiation angle, and light color temperature; Calculate the pre-installation position of the lighting device on the guide rail according to the first parameter; installing at least one lighting device to a pre-installed position; At least one lighting device is controlled to output a first lighting to the vehicle model.

[0039] Preferably, the first illumination includes: a first light intensity, a first light irradiation angle and a first light color temperature.

[0040] Specifically, during driving, the vehicle is exposed to light from multiple angles; therefore, by analyzing the collected simulated lighting information and relying on the lighting simulation system, the light angle and light intensity exposed to the vehicle are calculated, and the installation position of each lighting device on the guide rail is calculated based on the light angle and light intensity, and at least one lighting device located at the installation position is controlled according to the first parameter to output the first light to the vehicle model 10.

[0041] Furthermore, before obtaining the light information received by the sensing device, the control method further includes: Acquire a first light output by the lighting device; Comparing the first illumination with the simulated illumination information to generate correction data; Executing a correction strategy on the lighting device according to the correction data; wherein the correction strategy includes adjusting the first illumination to the correction illumination according to the correction data; Controlling the lighting device to output corrected lighting to the model part; Among them, correcting the lighting includes correcting the light intensity, correcting the light irradiation angle and correcting the color temperature.

[0042] Specifically, before outputting illumination to the vehicle model 10, the first illumination output by the illumination device 30 is compared with the simulated illumination information, i.e., the actual output illumination of the illumination device 30 is obtained; correction data is generated by comparing the actual output illumination with the simulated illumination information, i.e., the actual output illumination of the illumination device 30 is verified to see whether there is a deviation from the simulated illumination information; the illumination device is controlled to output illumination to the vehicle model 10 again according to the correction data, until the output illumination corrected by the correction data fits the simulated illumination information, and then the illumination device 30 is controlled to output the corrected illumination to the vehicle model 10.

[0043] In a specific example, a sensing device is set on the illumination surface of the lighting device 30, the first light output by the lighting device 30 is collected by the sensing device, and the first light is compared with the simulated light information to generate correction data of the first light. After multiple comparisons and fittings, until the corrected light output by the lighting device 30 fits the simulated light information, the lighting device 30 is controlled to output the corrected light to the vehicle model 10.

[0044] Preferably, at least one sensing device is disposed on a plane 5 cm away from the surface of the lighting device 30, which serves as a measuring point of a single lighting device 30; at this time, the light emitted by other lighting devices 30 has the least impact on the measured point.

[0045] Furthermore, at least one sensing device is arranged on the outer surface of the vehicle model 10, which is recorded as a first collection area; after controlling the lighting device to output correction light to the vehicle model, the control method further includes: Controlling the sensing device to collect the correction light in the first collection area to obtain first collection data; Comparing the first collected data with the corrected illumination to obtain first comparison information; Calculating a first light change parameter according to the first comparison information; The first light variation parameter includes: a natural light loss rate.

[0046] Specifically, after the output light of the lighting device 30 is calibrated, multiple sensing devices arranged on the outer surface of the vehicle model 10 are controlled to collect the corrected light, which is recorded as the first collected data; the first collected data is compared with the corrected light to calculate the first light change parameter in the process of propagating to the vehicle surface.

[0047] Preferably, the first light variation parameter is the natural light loss rate.

[0048] In simple terms, when the output illumination of the lighting device 30 matches the simulated illumination information, the natural loss rate of the light during the propagation process is calculated by collecting the corrected illumination.

[0049] In a specific example, the lighting simulation system has 52 lighting devices arranged in a matrix on the guide rail, represented by a matrix Y; ; Wherein, Z1 represents a first lighting device, Z2 represents a second lighting device, Z3 represents a third lighting device, and so on, for a total of 52 lighting devices 30; Then the surface brightness of these 52 lighting devices, that is, the corrected illumination of the lighting devices, is represented by the matrix C: ; Wherein, L1 represents the light luminance of the first lighting device, L2 represents the light luminance of the second lighting device, L3 represents the light luminance of the third lighting device, and so on, for a total of 52 light luminances of the lighting devices 30; The lighting simulation system is equipped with the same number of sensing devices corresponding to 52 lighting devices, which is represented by matrix B: ; Among them, S1 is the brightness of light collected by the first sensor, S2 is the brightness of light collected by the second sensor, S3 is the brightness of light collected by the third sensor, and so on, a total of 52 brightness values ​​collected by sensors; It should be noted that the light illuminance S1 collected by the first sensor is not equal to the light illuminance L1 of the first lighting device; similarly, Sn≠Ln, n∈{1, 2, 3...52}; From the surface brightness of the 52 lighting devices to the outer surface of the vehicle model 10 where the 52 sensing devices are located, the light intensity will be attenuated, and the light intensity measured by each sensing device is obtained by superimposing the light intensity components of the 52 lighting devices 30; then there will be a light change parameter from the surface of the lighting device 30 to the sensing device, that is, according to the first comparison information between the first collected data and the corrected light, the first light change parameter is calculated; wherein, the first light change parameter is represented by the relationship matrix A: ; The light variation parameter from each lighting device 30 to any sensing device can be represented by a ij To indicate, i indicates the corresponding lighting device, j indicates the corresponding sensing device; for example, a 11 represents the light change parameter from the first lighting device to the first sensing device, a 12 represents a parameter of light change from the first lighting device to the second sensing device, and so on; Therefore, the relationship between the lighting device 30 and the sensing device is shown in Formula 1; Formula 1: Right now ; Among them, m=52.

[0050] Since multiple groups of light illumination of the lighting device 30 are required when performing light fitting, multiple groups of matrices C are involved; therefore, the above formula 1 can be adjusted to the following formula 2: Formula 2: ; Right now ; Among them, k represents the current number of experimental groups, that is, the matrix C has a total of k groups of values ​​of "L1 to L52".

[0051] For example, when taking the surface brightness data of the first group of lighting devices, the matrix C （k） Represented as C （1） ; ; At the same time, substituting C1 into formula 2, we get: .

[0052] From this, we can get the natural loss rate of light when natural light shines on the outer surface of the vehicle during actual driving, that is, matrix A.

[0053] Furthermore, at least one sensing device is arranged in the cab of the vehicle model 10, which is recorded as a second collection area; after calculating the first light change parameter, the control method further includes: controlling the sensing device to collect the correction light in the second collection area to obtain second collection data; Comparing the second collected data with the corrected illumination to obtain second comparison information; Calculating a second light change parameter according to the second contrast information; The second light variation parameter includes: light propagation loss rate.

[0054] Specifically, continuing to take the above 52 lighting devices as an example, 52 sensing devices are also provided in the cab of the vehicle model 10. After knowing the natural light loss rate under natural conditions, the light in the cab of the vehicle model 10 is collected and compared with the correction light, the second light change parameter after the light passes through the vehicle model 10 can be obtained, that is, the light propagation loss rate of the light from the outside to the vehicle cabin; wherein, the second light change parameter is represented by the relationship matrix Q: ; The light change parameter from each lighting device to any sensing device can be represented by qij, where i represents the corresponding lighting device, and j represents the corresponding cab sensing device; for example, q11 represents the light change parameter from the first lighting device to the first cab sensing device, q12 represents the light change parameter from the first lighting device to the second cab sensing device, and so on; Therefore, the relationship between the lighting device 30 and the sensing device in the cab is shown in Formula 3; Formula 3: ; Right now ; Among them, m=52.

[0055] Similar to Formula 2, Formula 3 can also be adjusted to the following Formula 4; Formula 4: ; Right now ; Among them, k represents the current number of experimental groups, that is, the matrix C has a total of k groups of values ​​of "L1 to L52".

[0056] Furthermore, after calculating the second variation parameter, the control method further includes: obtaining the light attenuation degree according to the first light variation parameter and the second light variation parameter; Calculate the control parameters of the control device according to the light attenuation degree; Adjust the driving environment according to the control parameters.

[0057] Specifically, by comparing the matrix A and the matrix Q, it is possible to obtain the light change after the light passes through the vehicle model 10, that is, the light attenuation from the vehicle surface to the vehicle cabin; thus, the driving environment in the cab is appropriately adjusted according to the control parameters so that the driving environment in the cab meets the driver's driving habits. Further, the illumination output of the lighting device is calculated according to the first light change parameter, the second light change parameter and the illumination change difference.

[0058] For example, matrix A is a known quantity, according to formula 1: ; Inverse matrix C through matrix A.

[0059] Specifically, ; ; ; That is, the first change parameter, that is, matrix A, is verified by inversely solving matrix C.

[0060] Similarly, the second change parameter, ie, the matrix Q, can also be verified by inversely solving the matrix C, which will not be further illustrated.

[0061] Furthermore, the regulating device includes a front windshield located at the vehicle model; adjusting the driving environment according to the regulating parameters includes: Calculate the actual lighting environment in the cab based on the corrected lighting and the difference in lighting change; Comparing the actual lighting environment with the driving habits to generate second comparison information; The regulating device is controlled to execute the second processing strategy according to the second comparison information.

[0062] Preferably, the second processing strategy includes controlling the regulating device to adjust the light transmittance of the front windshield according to the regulating parameters.

[0063] Furthermore, the illumination simulation system 100 further includes: a protection module; the control method further includes: judging whether there is a sudden change in light during the driving journey according to weather information and the driving journey; If yes, the control protection module issues a warning to the user and controls the adjustment device to execute the third processing strategy according to the control parameters; The third processing strategy includes turning on all vehicle lighting devices or adjusting the sun visor to a shielding state.

[0064] For example, the lighting simulation environment is driving in a mountainous area. The lighting conditions during driving are predicted based on the actual weather information collected. For example, if the vehicle is about to enter a shaded area in the mountainous area, a valley, or is about to encounter cloud cover, the protection module will issue an early warning to the user, reminding the driver to pay attention to light changes and be mentally prepared in advance.

[0065] Furthermore, if it is detected that the light is about to dim, the light transmittance of the vehicle's front windshield will be adjusted accordingly based on the first collected data and the second collected data, and the driver will be reminded to turn on the lights.

[0066] Furthermore, when a sudden change in light causes excessive light, the adjustment device will automatically adjust the sun visor to a blocked state to reduce the stimulation of strong light to the driver's eyes; at the same time, the current control parameters are calculated based on the first collected data and the second collected data, and the adjustment device is controlled to adjust the transmittance of the front windshield to reduce the intensity of light entering the vehicle.

[0067] Further, if Figure 2As shown, the present invention also provides a lighting simulation system for an intelligent cockpit, which can implement any of the above-mentioned control methods.
