[0071] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0072] With the rapid increase in the number of cars and the rapid development of the transportation and tourism industries, cars have become an indispensable means of transportation in modern life, and the resulting travel safety and comfort issues have received widespread attention. Among them, the illumination inside the car not only affects the driver's driving safety, but also affects the riding experience of the passengers in the car.

[0073] In the prior art, there is a kind of dimming glass, which is a new type of special photoelectric glass product with a sandwich structure that is formed by compounding a liquid crystal film between two layers of glass and gluing them together under high temperature and high pressure. After this dimming glass is applied to a car, the user can control the transparency and opacity of the glass by manually adjusting the on and off of the control voltage. However, controlling the transparency of the car glass by manual adjustment will affect driving safety. In addition, there is another dimming method in the prior art, which is to cover a layer of electroluminescent film on the surface of the glass, and change the transparency of the electroluminescent film by changing the control current, thereby completing the dimming. However, because it is covered on the surface of the glass, it is easy to cause damage or breakage.

[0074] Based on this, the embodiments of the present application provide a method, system, electronic device and storage medium for adjusting the interior light illumination, which automatically controls the transmittance of the dimming layer in the dimming glass to be dimmed according to the interior environment parameters and the exterior environment parameters, thereby realizing automatic adjustment of the interior light illumination.

[0075] See also Figure 1 , Figure 1 A flow chart of a method for adjusting the illumination in a vehicle provided in an embodiment of the present application. The adjustment method is applied to an adjustment system for the illumination in a vehicle, and the adjustment system includes an environmental parameter sensor, a microprocessor, a vehicle locator, and an operational amplifier. The microprocessor is connected to the environmental parameter sensor, the microprocessor, the vehicle locator, and the operational amplifier, respectively. Among them, the communication mode of the adjustment system can adopt a LIN communication mode to transmit data and commands, thereby avoiding the problem of communication congestion caused by multiple nodes of CAN communication.

[0076] like Figure 1 As shown, the adjustment method provided in the embodiment of the present application includes:

[0077] S101, the environmental parameter sensor collects the in-vehicle environmental parameters and the out-vehicle environmental parameters of the target vehicle, and sends the collected in-vehicle environmental parameters and the out-vehicle environmental parameters to the microprocessor.

[0078] Here, the target vehicle may be any vehicle that requires interior illumination adjustment, such as a passenger car, a subway, a high-speed train, or a bus.

[0079] In an implementation manner provided in the present application, the environmental parameter sensor includes a first light sensor, a second light sensor, and a temperature sensor.

[0080] When factors such as replacement convenience and procurement cost need to be considered, the light sensor can use two photoresistors to collect light values, and the temperature sensor can use a thermistor to collect temperature.

[0081] In another embodiment provided in the present application, the environmental parameter sensors collect the in-vehicle environmental parameters and out-vehicle environmental parameters of the target vehicle, including: collecting the outdoor light illumination of the target vehicle by the first light sensor; collecting the indoor light illumination of the target vehicle by the second light sensor; and collecting the indoor temperature of the target vehicle by the temperature sensor.

[0082] Here, the first light sensor is placed outside the target vehicle to collect vehicle light intensity, and can be specifically placed at any vertex or edge outside the glass to be dimmed.

[0083] For examples, see Figure 2 , Figure 2 A structural schematic diagram of the setting position of the environmental parameter sensor provided in this application; when the glass to be dimmed is a sunroof glass, the first light sensor is placed at the top corner end outside the sunroof glass (any top corner end is acceptable), and the second light sensor and the temperature sensor are placed in the sunroof operating area inside the vehicle.

[0084] S102: The vehicle-mounted locator collects the position data of the target vehicle and sends the collected position data to the microprocessor.

[0085] Here, the reason for collecting the location information of the target vehicle is to determine the area where the target vehicle is currently located, because different areas may correspond to different dimming solutions.

[0086] S103: The microprocessor selects target environmental parameters from the in-vehicle environmental parameters and the out-vehicle environmental parameters based on the position data and according to pre-set screening rules.

[0087] Here, the microprocessor may be a processor of the KEA128 series. It should be noted that the KEA series MCU (microcontroller unit) is a highly scalable 32-bit ARM Cortex-M0+ MCU portfolio for the automotive market. The series is optimized for cost-sensitive applications, offering low pin count options and extremely low power consumption. The KEA series MCU uses a 2.7-5.5V power supply and focuses on excellent EMC / ESD robustness, making it ideal for a wide range of applications, from body applications, security companion chips, or general sensor nodes. In automotive body applications, the KEA series MCU is an excellent choice for entry-level body controllers or gateway modules, window / sunroof / moonroof controllers, immobilizers, or seat / mirror controllers.

[0088] In one embodiment provided in the present application, based on the location data, according to pre-set screening rules, the target environmental parameters are screened out from the in-vehicle environmental parameters and the out-vehicle environmental parameters, including: based on the location data, determining whether the target vehicle is located in a high-cold area or a high-heat area; wherein the location range of the high-cold area and the location range of the high-heat area are pre-set; when it is determined that the target vehicle is located in a high-cold area, the outside light illuminance, the inside light illuminance and the inside temperature are determined as target environmental parameters; when it is determined that the target vehicle is located in a high-heat area, the outside light illuminance and the inside light illuminance are determined as target environmental parameters.

[0089] Here, when the acquired position data is within the position range of the high-cold area, it is determined that the target vehicle is located in the high-cold area; when the acquired position data is within the position range of the high-heat area, it is determined that the target vehicle is located in the high-heat area.

[0090] The location range of high-cold areas and high-heat areas can be adaptively delineated. Taking China as an example, the area north of the Qinling-Huaihe line can be defined as a high-cold area, and the area south of the Qinling-Huaihe line can be defined as a high-heat area.

[0091] S104. The microprocessor determines a target adjustment position of a dimming layer in a target glass to be dimmed of the target vehicle based on the target environmental parameter and a preset environmental parameter threshold value and according to a preset dimming rule, generates a dimming indication signal based on the determined target dimming position, and sends the dimming indication signal to an operational amplifier.

[0092] Here, the target glass to be dimmed is a double-layer dimming glass filled with dye liquid crystal molecules, and different adjustment gears correspond to different transmittances of the dimming layer. The preset dimming rule is a rule for recording the corresponding relationship between the target environmental parameters and the preset environmental parameter threshold and the adjustment gear.

[0093] The target glass to be dimmed may be a windshield, a skylight, a door glass, etc.

[0094] In an embodiment provided in the present application, the determining, based on the target environmental parameter and the preset environmental parameter threshold, according to the preset dimming rule, the target adjustment gear of the dimming layer in the target glass to be dimmed of the target vehicle includes:

[0095] When the target vehicle is located in a high-heat area, the target illuminance is obtained by subtracting the illuminance inside the vehicle from the illuminance outside the vehicle; determining whether the target illuminance is greater than a first preset illuminance threshold, and determining whether the illuminance outside the vehicle is greater than a second preset illuminance threshold; when either one is no, dimming is not performed; when both are yes, dimming is performed.

[0096] The dimming process may include: when the target light illumination is greater than a first preset light illumination threshold and is less than or equal to a third preset light illumination threshold, determining a preset first gear as a target adjustment gear of the dimming layer; when the target light illumination is greater than the third preset light illumination threshold and is less than or equal to a fourth preset light illumination threshold, determining a preset second gear as a target adjustment gear of the dimming layer; when the target light illumination is greater than the fourth preset light illumination threshold and is less than or equal to a fifth preset light illumination threshold, determining a preset third gear as a target adjustment gear of the dimming layer; when the target light illumination is greater than the fifth preset light illumination threshold, determining a preset fourth gear as a target adjustment gear of the dimming layer.

[0097] For example, the first preset illuminance threshold can be set to 1500 lux, the second preset illuminance threshold can be set to 8000 lux, the third preset illuminance threshold can be set to 4000 lux, the fourth preset illuminance threshold can be set to 7000 lux, and the fifth preset illuminance threshold can be set to 12000 lux. The first preset gear is that the liquid crystal flip rate in the target glass to be dimmed is 25%, that is, the glass transmittance is 80%; the second preset gear is that the liquid crystal flip rate in the target glass to be dimmed is 50%, that is, the glass transmittance is 65%; the third preset gear is that the liquid crystal flip rate in the target glass to be dimmed is 75%, that is, the glass transmittance is 40%; the fourth preset gear is that the liquid crystal flip rate in the target glass to be dimmed is 100%, that is, the glass transmittance is 15%.

[0098] When the target vehicle is located in a high-cold area, the target illuminance is obtained by subtracting the illuminance inside the vehicle from the illuminance outside the vehicle; determine whether the target illuminance is greater than a first preset illuminance threshold, whether the illuminance outside the vehicle is greater than a second preset illuminance threshold, and whether the temperature inside the vehicle is greater than a preset temperature value; when any one of them is no, dimming is not performed; when all three are yes, dimming is performed.

[0099] The dimming process may include: when the target light illumination is greater than a first preset light illumination threshold and is less than or equal to a third preset light illumination threshold, determining a preset first gear as a target adjustment gear of the dimming layer; when the target light illumination is greater than the third preset light illumination threshold and is less than or equal to a fourth preset light illumination threshold, determining a preset second gear as a target adjustment gear of the dimming layer; when the target light illumination is greater than the fourth preset light illumination threshold and is less than or equal to a fifth preset light illumination threshold, determining a preset third gear as a target adjustment gear of the dimming layer; when the target light illumination is greater than the fifth preset light illumination threshold, determining a preset fourth gear as a target adjustment gear of the dimming layer.

[0100] For example, the preset temperature value may be set to 25 degrees Celsius.

[0101] S105, the operational amplifier changes and adjusts the driving voltage of the dimming layer in the target glass to be dimmed according to the dimming indication signal, so that the adjustment gear position of the dimming layer in the target glass to be dimmed is the target adjustment gear position, thereby completing the adjustment of the interior light illumination.

[0102] Here, the operational amplifier model in question is the OPA547. It should be noted that this is a low-cost, high-voltage / high-current operational amplifier that is ideal for driving a variety of loads. The laser-trimmed monolithic integrated circuit provides excellent low-level signal accuracy and high output voltage and current. The OPA547 operates with single or dual supplies for design flexibility. In single-supply operation, the input common-mode range extends below ground. The OPA547 has internal protection to prevent overtemperature conditions and current overloads. In addition, the OPA547 is designed to provide accurate, user-selected current limits. Unlike other designs that use a "power" resistor in series with the output current path, the OPA547 senses the load indirectly. This allows the current limit to be adjusted from 0mA to 750mA with a control signal from 0 to 150μA. This is easily accomplished using a resistor / potentiometer, or digitally controlled using a voltage output or current output DAC. The enable / status (E / S) pin provides two functions. The input on the pin not only disables the output stage to effectively disconnect the load, but also reduces the quiescent current to save power. The E / S pin output can be monitored to determine if the OPA547 is in thermal shutdown.

[0103] In an embodiment provided in the present application, the dimming layer in the target glass to be dimmed is pre-divided into at least one dimming zone, and the operational amplifier changes and adjusts the driving voltage of the dimming layer in the target glass to be dimmed according to the dimming indication signal, including: the operational amplifier changes and adjusts the driving voltage of at least one target dimming zone in the dimming layer in the target glass to be dimmed according to the dimming indication signal; wherein the dimming indication signal includes an indication signal of the at least one target dimming zone.

[0104] Here, by partitioning the dimming layer in advance, more accurate illumination adjustment in the vehicle can be achieved, and the needs of passengers in different positions can be met to a greater extent. The dimming indication signal includes the indication signal of the at least one target dimming zone, which is used to tell the operational amplifier which specific dimming zone in the dimming layer to dim. The indication signal of the target dimming zone can be preset, or generated in response to a user's selected operation.

[0105] In another embodiment provided in the present application, the adjustment system also includes an analog-to-digital converter, and the sending of the collected in-vehicle environmental parameters and outside-vehicle environmental parameters to the microprocessor includes: the environmental parameter sensor sends the collected analog signals of the in-vehicle environmental parameters and outside-vehicle environmental parameters to the analog-to-digital converter; the analog-to-digital converter performs analog-to-digital conversion based on the received analog signals of the in-vehicle environmental parameters and outside-vehicle environmental parameters, and transmits the converted digital signals of the in-vehicle environmental parameters and outside-vehicle environmental parameters in a specific digital form to the microprocessor for processing.

[0106] Here, the analog-to-digital converter may use a signal converter of the ADC121S101 model. It should be noted that this is a low-power, single-channel CMOS 12-bit analog-to-digital converter with a high-speed serial interface. Unlike the traditional practice of specifying performance only at a single sampling rate, the ADC121S101 is fully specified in a sampling rate range of 500ksps to 1Msps. The converter is based on a successive approximation register architecture with an internal sample-and-hold circuit.

[0107] In another embodiment provided in the present application, the adjustment system also includes a digital-to-analog converter, and sending the dimming indication signal to the operational amplifier includes: the microprocessor sending the dimming indication signal in the form of a digital signal to the digital-to-analog converter; the digital-to-analog converter performing digital-to-analog conversion on the dimming indication signal in digital form to obtain a dimming indication signal in analog form, and sending the dimming indication signal in analog form to the operational amplifier.

[0108] Here, the digital-to-analog converter may adopt a signal converter of the LTC2641 model. It should be noted that the LTC2641 provides 16-bit performance (±1LSB INL and ±1LSB DNL) over the entire temperature range. The unbuffered DAC output results in a low supply current of 120μA and a low offset error of ±1LSB. The LTC261 has a reference input range of 2V to VDD. VOUT swings from 0V to VREF. For bipolar operation, the LTC2641 includes matching scaling resistors used with an external precision operational amplifier to produce ±VREF output swings at RFB. The LTC2641 uses a simple SPI / MICROWIRE-compatible 3-wire serial interface operable with a clock frequency of up to 50MHz and can be directly connected with an optocoupler for applications requiring isolation.

[0109] In another embodiment provided in the present application, the regulation system further includes a power monitor, and the regulation method further includes: the power monitor monitors the operating power of the regulation system, obtains a monitoring result, and sends the monitoring result to the microprocessor.

[0110] Here, the monitoring results can be directly fed back to the backend or on-board personnel so that abnormal monitoring results can be processed in a timely manner.

[0111] In another implementation manner provided in the present application, the regulation system further includes a power supply module, and the regulation method further includes: the power supply module provides a working voltage for the regulation system.

[0112] Here, the power supply module can use a step-down DC power supply model LMZM23600. The LMZM23600 integrated inductor module is designed for space-constrained industrial applications and provides fixed output voltage options of 5V and 3.3V and adjustable (ADJ) output voltage options in the range of 2.5V to 15V. The LMZM23600 supports an input voltage range of 4V to 36V and can provide an output current of up to 500mA. All aspects of the LMZM23600 are optimized for space-constrained, performance-driven, low-EMI industrial applications. The open-drain power-normal output provides a true indication of the system status without the need for additional monitoring components, saving cost and board space. Seamless transitions between PWM and PFM modes and a no-load power supply current of only 30μA ensure high efficiency and excellent transient response over the entire load current range.

[0113] In addition, the regulation system also includes a reset module, which can reset the entire system in the event of an operation error or crash of the regulation system, thereby ensuring long-term stable operation of the system.

[0114] The adjustment system also includes a flash memory module, which provides storage of preset parameters and cache space for subsequent upgrades.

[0115] Thus, the technical solution disclosed in the present application has the following advantages compared with the prior art: an automatic dimming system is realized by the cooperation of three sensors, thus avoiding the cumbersome manual triggering mode; a more stable and accurate automatic dimming processing mechanism can be realized by building in two sets of programs for different regions; false triggering and insensitivity can be effectively avoided by adding a power monitor; more accurate in-vehicle light intensity adjustment can be achieved by setting adjustment gears and zone adjustments; and the service life is increased by adopting double-layer dimmable glass filled with dye liquid crystal molecules.
