Description

[0001] This invention relates to the field of vehicle lighting control, and more specifically, to a method, system, storage medium, and vehicle for controlling vehicle lighting. Background Technology

[0002] Currently, with the increasing demand for privacy from users, privacy glass is being used more and more in vehicles. The lower the transmittance of the glass, the lower the light transmittance of the interior high-mounted brake light. To meet the specified light intensity requirements, the number of LED (Light Emitting Diode) beads must be increased or LED beads with higher power must be selected to meet the light distribution requirements. This will result in the heat of the lamp not meeting the safety requirements, and an increase in lamp cost and weight.

[0003] Meanwhile, in order to meet the different user requirements, vehicles are usually equipped with privacy and non-privacy glass depending on the configuration. This results in the need to equip high-mounted brake lights with different configurations to adapt to different types of glass. This requires the development of two sets of high-mounted brake lights, which increases development and management costs. Consequently, the same light fixture has low adaptability to different glass transmittance.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0011] Furthermore, in response to the fact that the transmittance information is not affected by the target factors, the product of the transmittance information and the second calibration parameter is obtained to obtain the adjustment parameters for the high-mounted brake lamp.

[0012] Furthermore, based on the adjustment parameters, the high-mounted brake light is controlled, including: obtaining the electrical parameters for controlling the high-mounted brake light based on the adjustment parameters; and controlling the high-mounted brake light based on the electrical parameters.

[0013] According to another aspect of the present invention, a vehicle lighting control system is also provided, comprising: a body control module for acquiring transmittance information of vehicle glass; and a high-mounted brake light module for controlling the high-mounted brake light by providing illumination intensity corresponding to the type of driving light source based on the transmittance information, wherein the body control module and the high-mounted brake light module communicate through a controller local area network.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0026] Example 1

[0027] According to an embodiment of the present invention, an embodiment of a vehicle lighting control method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0028] Figure 1 This is a flowchart of a vehicle lighting control method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0029] Step S102: Obtain the transmittance information of the vehicle glass;

[0030] Specifically, the transmittance information mentioned above can be used to indicate the degree to which light can pass through the glass, and is generally expressed as a percentage.

[0031] Generally, the higher the transmittance of vehicle glass, the more light can pass through, making the interior of the car brighter; conversely, the lower the transmittance, the less light can pass through, making the interior of the car darker.

[0032] In one optional embodiment, during the process of controlling the vehicle lights, it is necessary to obtain the transmittance information of the vehicle glass, and then adjust the light intensity of the high-mounted brake light on the vehicle based on the transmittance information to achieve the light intensity under different transmittance.

[0033] In another optional embodiment, during the process of acquiring the transmittance information of the vehicle glass, the transmittance of the vehicle glass can be identified by the body controller to obtain the aforementioned transmittance information. Generally, for high-end privacy glass, the transmittance information identified by the body controller is lower, while for low-end non-privacy glass, the transmittance information identified by the body controller is relatively higher.

[0034] Step S104: Based on the transmittance information, determine the type of driving light source for the vehicle, wherein the type of driving light source is used to characterize the type of light source driven by the high-mounted brake lamp of the vehicle.

[0035] Specifically, the aforementioned high-mounted brake light is a brake light installed high at the rear of the vehicle, typically above the rear window, in the center of the roof. This installation aims to improve the visibility of the high-mounted brake light, making it easier for following vehicles to notice the braking signal and thus reducing rear-end collisions. It is higher than a regular brake light, making it more easily noticed by following vehicles. The high-mounted brake light illuminates during sudden or emergency braking, reminding following vehicles to slow down or maintain a safe distance.

[0036] The above-mentioned driving light source type can be used to refer to the type of light source driven by the high-mounted brake light in the vehicle. Generally, it can be a common LED light source or a laser light source. There is no specific limitation on the driving light source type here.

[0037] In one alternative embodiment, after obtaining the transmittance information of the vehicle glass, it is necessary to determine the type of the vehicle's driving light source based on the obtained transmittance information.

[0038] Generally, when the transmittance information is low, the light transmittance of the high-mounted brake light inside the vehicle is also low. During emergency braking, following vehicles have difficulty clearly detecting the braking signal. Therefore, to improve the light transmittance of the high-mounted brake light, the vehicle's drive light source type needs to be determined to be a light source with high light intensity and low heat dissipation. Conversely, when the transmittance information is high, the light transmittance of the high-mounted brake light inside the vehicle is also high. During emergency braking, following vehicles can clearly detect the braking signal. Therefore, the vehicle's drive light source type should be determined to be a general drive light source.

[0039] It should be noted that when the transmittance information is low, in order to improve the light transmittance of the high-mounted brake light inside the vehicle, it is inevitable to increase the light intensity of the high-mounted brake light. At the same time, the high-mounted brake light will also generate more heat. Therefore, it is necessary to determine that the type of driving light source of the vehicle is a type of light source with high light intensity and low heat dissipation.

[0040] Step S106: Determine the adjustment parameters for the high-position brake lamp based on the type of driving light source;

[0041] Specifically, the aforementioned adjustment parameters can be used to represent parameters for adjusting the illumination intensity of the high-mounted brake light.

[0042] In one alternative embodiment, after determining the type of driving light source for the vehicle, it is necessary to determine the adjustment parameters for the high-mounted brake lamp based on the different types of driving light sources. Generally, due to the differences in driving light source types, the light intensity adjustment parameters for different types of driving light sources in the high-mounted brake lamp will differ.

[0043] Optionally, if the vehicle's drive light source is determined to be a type of light source with high light intensity and low heat dissipation, then during the process of adjusting the light intensity of the high-mounted brake light using adjustment parameters, even slight parameter adjustments can easily cause large fluctuations in light intensity. Conversely, if the vehicle's drive light source is determined to be a general drive light source, then during the process of adjusting the light intensity of the high-mounted brake light using adjustment parameters, it is difficult for parameter adjustments to cause large fluctuations in light intensity. Therefore, given a fixed adjusted light intensity, the adjustment parameters for different types of drive light sources will differ.

[0044] For example, when the adjusted light intensity meets 10W, if the vehicle's drive light source type is a type of light source with high light intensity and low heat dissipation, the adjustment parameter for the high-mounted brake light is a1; if the vehicle's drive light source type is a general drive light source, the adjustment parameter for the high-mounted brake light is a2, where a1 < a2.

[0045] Step S108: Control the high-position brake light based on the adjustment parameters.

[0046] Specifically, after determining the adjustment parameters for the high-mounted brake light, the high-mounted brake light can be controlled based on these parameters. Generally, it is necessary to determine the control parameters for the high-mounted brake light based on the adjustment parameters, and then control the high-mounted brake light using these control parameters. These control parameters can be used to represent the control parameters in the control circuit corresponding to the high-mounted brake light.

[0047] In summary, this method involves acquiring the transmittance information of vehicle glass; determining the type of driving light source for the vehicle based on this transmittance information, where the driving light source type characterizes the type of light source driving the high-mounted brake lamp; determining the adjustment parameters for the high-mounted brake lamp based on the driving light source type; and controlling the high-mounted brake lamp based on these adjustment parameters. It is noteworthy that by using different glass transmittance information to determine the driving light source type of the high-mounted brake lamp in the vehicle, and then determining the adjustment parameters for different types of driving light sources, the high-mounted brake lamp can be controlled by adjusting these parameters. This achieves the goal of adjusting the corresponding adjustment parameters based on different glass transmittances, thereby reducing costs and increasing efficiency. This improves the adaptability of the high-mounted brake lamp to different glass transmittances, thus solving the technical problem of low adaptability of the high-mounted brake lamp to different glass transmittances in related technologies.

[0048] Optionally, based on transmittance information, the type of driving light source for the vehicle is determined, including: in response to transmittance information being less than a preset transmittance, determining the type of driving light source as a laser light source; and in response to transmittance information being greater than or equal to a preset transmittance, determining the type of driving light source as a light-emitting diode light source.

[0049] Specifically, the aforementioned preset transmittance can be used to represent the preset glass transmittance, which can be 30% or 31%. There is no specific limitation on the preset transmittance here, and it can be adjusted according to the actual situation.

[0050] The aforementioned laser source is a monochromatic, coherent, and high-brightness light source generated by the electromagnetic radiation of a laser. Laser sources have the characteristics of narrow spectral width, high brightness, good directionality, and strong coherence.

[0051] The aforementioned light-emitting diode (LED) light source is a device that generates light through the recombination of electrons and holes in solid semiconductor materials. It features high efficiency, low power consumption, long lifespan, and fast response.

[0052] Generally, laser light sources have higher brightness and power than LED light sources, and have higher beam quality; while LED light sources have relatively lower brightness and power. Laser light sources typically have a smaller emission angle and a more concentrated beam; while LED light sources have a larger emission angle and a more scattered beam.

[0053] In one optional embodiment, during the process of determining the type of driving light source for a vehicle based on transmittance information, in response to the transmittance information being less than a preset transmittance, that is, the transmittance information being less than a preset glass transmittance, indicating that the transmittance information is small, the type of driving light source is determined to be a laser light source, so that the high-mounted brake light can emit high-intensity light through the laser light source, thereby ensuring that the following vehicle can quickly detect the braking signal of this vehicle when the vehicle brakes in an emergency.

[0054] In another optional embodiment, in response to the transmittance information being greater than or equal to a preset transmittance, indicating that the transmittance information is greater than or equal to a preset glass transmittance, indicating that the transmittance information is large, the driving light source type is determined to be a light-emitting diode light source, so that the high-mounted brake lamp emits light of normal intensity through the light-emitting diode light source, thereby ensuring that the following vehicle can quickly detect the braking signal of this vehicle when the vehicle brakes in an emergency.

[0055] In summary, by determining whether the transmittance information meets the preset transmittance, the type of driving light source is determined, thus enabling the configuration of different driving light source types for the same luminaire.

[0056] Optionally, the type of driving light source of the vehicle is determined to be a light-emitting diode (LED) light source. Based on the type of driving light source, the adjustment parameters for the high-mounted brake lamp are determined, including: determining a first calibration parameter for calibrating the LED light source; and obtaining the product of transmittance information and the first calibration parameter to obtain the adjustment parameters for the high-mounted brake lamp.

[0057] Specifically, the aforementioned first calibration parameter can be used to represent the parameter for calibrating the intensity of the light-emitting diode light source in the high-mounted brake lamp.

[0058] In one optional embodiment, when the vehicle's driving light source type is determined to be a light-emitting diode (LED) light source, in the process of determining the adjustment parameters for the high-mounted brake lamp based on the driving light source type, it is necessary to determine a first calibration parameter for calibrating the LED light source, and then obtain the adjustment parameters for the high-mounted brake lamp by multiplying the transmittance information and the first calibration parameter.

[0059] In another optional embodiment, in the process of determining the first calibration parameter for calibrating the LED light source, the calibration parameter of the LED light source can be calibrated multiple times. By screening the multiple light source intensities obtained after calibration, the target calibration parameter corresponding to the target light source intensity with the largest intensity and the smallest heat dissipation can be determined, and then the target calibration parameter can be determined as the first calibration parameter mentioned above.

[0060] Optionally, the vehicle's driving light source type is determined to be a laser light source. Based on the driving light source type, adjustment parameters for the high-mounted brake lamp are determined, including: determining a second calibration parameter for calibrating the laser light source; and obtaining the adjustment parameters for the high-mounted brake lamp based on transmittance information and the second calibration parameter.

[0061] Specifically, the aforementioned second calibration parameter can be used to represent the parameter for calibrating the intensity of the laser source in the high-mounted brake lamp, wherein the second calibration parameter is less than the first calibration parameter.

[0062] In one optional embodiment, if the vehicle's drive light source type is determined to be a laser light source, in the process of determining the adjustment parameters for the high-mounted brake lamp based on the drive light source type, it is necessary to determine a second calibration parameter for calibrating the laser light source, and then obtain the adjustment parameters for the high-mounted brake lamp based on the transmittance information and the second calibration parameter.

[0063] In another optional embodiment, in the process of determining the second calibration parameter for calibrating the laser source, the calibration parameter of the laser source can be calibrated multiple times. By screening the multiple light source intensities obtained after calibration, the target calibration parameter corresponding to the target light source intensity with the largest intensity and the smallest heat dissipation can be determined, and then the target calibration parameter can be determined as the second calibration parameter mentioned above.

[0064] In a third alternative embodiment, under the same control parameters, the intensity of the light-emitting diode light source is less than that of the laser light source. Therefore, in the process of calibrating the light intensity of different driving light source types using calibration parameters, different calibration parameters need to be matched for different driving light source types. And through experiments, it is determined that the first calibration parameter for calibrating the light-emitting diode light source is greater than the second calibration parameter for calibrating the laser light source.

[0065] Optionally, based on transmittance information and a second calibration parameter, the adjustment parameters for the high-mounted brake light are obtained, including: determining whether the transmittance information is affected by a target factor; in response to the transmittance information being affected by the target factor, obtaining the transmittance information affected by the target factor; obtaining the sum of the transmittance information and the transmittance information affected by the target factor; obtaining the product of the sum and the second calibration parameter to obtain the adjustment parameters for the high-mounted brake light.

[0066] Specifically, the target factors mentioned above can be used to represent factors that affect glass transmittance. These can be weather factors such as fog, rain, and snow, or factors such as the thickness, color, and coating of vehicle glass. No specific limitations are imposed on the target factors here.

[0067] Generally, the greater the thickness of the glass, the lower the transmittance may be. For example, thicker glass may block some light, thus affecting the transmittance. Different colored glass will also affect the transmittance of light. For example, dark glass will absorb more light, resulting in lower transmittance. Some vehicle glass may be coated with special coatings, such as heat-insulating coatings or sound-insulating coatings, which will also affect the transmittance.

[0068] The aforementioned information on transmittance can be used to represent the impact of the aforementioned target factors on the transmittance of vehicle glass.

[0069] Generally, the presence of the aforementioned target factors will lead to a decrease in the transmittance of vehicle glass.

[0070] In one optional embodiment, during the process of obtaining the adjustment parameters for the high-mounted brake light based on the transmittance information and the second calibration parameter, it can be determined whether the transmittance information is affected by the target factor. If the transmittance information is affected by the target factor, it indicates that the transmittance information of the glass may decrease, resulting in a decrease in the visibility of the light source of the high-mounted brake light. Therefore, it is necessary to obtain the transmittance information corresponding to the target factor, and then sum the transmittance information and the transmittance information, and multiply the summation result with the second calibration parameter to obtain the adjustment parameters of the high-mounted brake light corresponding to the product.

[0071] In another optional embodiment, during the process of obtaining the influence transmittance information corresponding to the target factor, the target factor can be sensed by a sensor monitoring module, and the sensed information can be uploaded to a central processing unit for information processing to obtain the influence transmittance information corresponding to the target factor. For example, if a smoke sensor detects smoke in the vehicle, the smoke concentration detected by the sensor can be uploaded to the central processing unit for data processing to obtain the influence transmittance information generated by the smoke.

[0072] Optionally, in response to the fact that the transmittance information is not affected by the target factor, the product of the transmittance information and the second calibration parameter is obtained to obtain the adjustment parameter for the high-position brake lamp.

[0073] Specifically, in response to the fact that the transmittance information is not affected by the target factor, indicating that the transmittance information of the glass is unaffected, the product of the transmittance information and the second calibration parameter can be obtained, and the product can be used as the adjustment parameter for the high-mounted brake light.

[0074] Optionally, controlling the high-mounted brake light based on adjustment parameters includes: obtaining electrical parameters for controlling the high-mounted brake light based on the adjustment parameters; and controlling the high-mounted brake light based on the electrical parameters.

[0075] Specifically, the aforementioned electrical parameters can be used to represent the parameters corresponding to the control circuit in the high-mounted brake light, that is, voltage parameters or current parameters. By adjusting the control circuit through electrical parameters, the control of the high-mounted brake light can be achieved.

[0076] In one alternative embodiment, during the process of controlling the high-mounted brake light based on the adjustment parameters, electrical parameters for controlling the high-mounted brake light can be obtained based on the adjustment parameters, and the high-mounted brake light can be controlled through the electrical parameters.

[0077] Generally, since the adjustment parameter reflects the light intensity of the high-mounted brake light, the larger the adjustment parameter, the larger the corresponding electrical parameter.

[0078] Figure 2This is an optional flowchart for determining transmittance information according to an embodiment of the present invention. For example... Figure 2 As shown, firstly, the vehicle's glass transmittance information is identified through the BCM (Body Control Module); then, it is determined whether the glass transmittance information is less than or equal to 30%; if the glass transmittance information is greater than 30%, the driving light source type is determined to be an LED light source, and the LED light source in the high-mounted brake light is driven, and the light source intensity is adjusted through PWM (Pulse Width Modulation) to obtain the adjusted light intensity = glass transmittance * first calibration parameter; if the glass transmittance information is less than or equal to 30%, it is determined whether there are target factors affecting transmittance; if there are target factors affecting transmittance, the driving light source type is determined to be a laser light source, and the light source intensity is adjusted through PWM to obtain the adjusted light intensity = (glass transmittance + affected transmittance) * second calibration parameter; if there are no target factors affecting transmittance, the driving light source type is determined to be a laser light source, and the light source intensity is adjusted through PWM to obtain the adjusted light intensity = glass transmittance * second calibration parameter.

[0079] Figure 3 This is an optional circuit diagram for controlling lights according to an embodiment of the present invention. Figure 3 As shown, this includes a driver module and a light board module. In the driver module: PIN1 is KL30, the positive terminal for battery power; PIN4 is GND (ground); PIN5 is KL15, the signal for starting the vehicle; PIN2 is CANH, used to receive high-level CAN (Controller Area Network) signals; and PIN3 is CANL, used to receive low-level CAN signals. The MCU (Main Control Unit) is the core control unit of the vehicle's electronic system, responsible for managing and controlling various vehicle functions and systems.

[0080] The internal control system circuit of the lamp includes a CAN transceiver module, an MCU main control chip, a driver chip, and a driver light source. The lamp receives power signals from the vehicle and communicates via CAN, transmitting the signals to the MCU. The MCU processes the signals and sends corresponding commands to the driver chip, which then drives the laser light source to turn on and off. The lamp is connected to the vehicle's battery, ensuring a constant power input whether the vehicle is operating or not. In addition, the CAN transceiver module can also receive and transmit commands from the MCU.

[0081] In summary, the vehicle headlight controller obtains the vehicle's glass transmittance information through the body controller and transmits the transmittance information to the high-mounted brake light. The high-mounted brake light, in combination with different glass transmittance information, provides different driving light source intensities to meet the light intensity requirements under different glass transmittance conditions.

[0085] The vehicle body control module 41 is used to acquire the transmittance information of the vehicle glass;

[0086] Specifically, the aforementioned body control module 41 can perform CAN communication to obtain the transmittance information of the vehicle's glass. For example... Figure 4 As shown, the body control module includes a logic operation module and a CAN transceiver module, wherein the logic operation module is implemented through an MCU.

[0087] The high-mounted brake light module 42 is used to provide the illumination intensity corresponding to the type of drive light source based on transmittance information, and to control the high-mounted brake light. The vehicle body control module and the high-mounted brake light module communicate through a controller local area network.

[0088] Specifically, the aforementioned high-mounted brake light module 42 can perform CAN communication to provide the light intensity corresponding to the type of drive light source based on transmittance information, and control the high-mounted brake light.

[0089] In one alternative embodiment, such as Figure 4 As shown, after obtaining the transmittance information of the vehicle glass, the body control module 41 can communicate through the controller local area network to transmit the transmittance information to the high-mounted brake light. After receiving the transmittance information, the high-mounted brake light module 42 provides the light intensity corresponding to the type of driving light source and controls the high-mounted brake light through the light intensity.
