Description

Technical Field

[0001] This invention belongs to the field of automotive technology. Specifically, this invention relates to a vehicle ventilation method, system, and vehicle. Background Technology

[0002] With the development of intelligent vehicles, the requirements for cabin comfort and energy efficiency are constantly increasing. Most existing vehicle ventilation systems use overall air volume control, which cannot control the airflow in zones according to the area exposed to sunlight, resulting in uneven heating and cooling in some areas and high energy consumption.

[0003] Meanwhile, existing sunlight sensors have a single function, only used to detect light intensity to trigger the automatic start of air conditioning or adjust the total air volume. They do not have the ability to identify areas, cannot accurately determine the specific location of sunlight, and cannot provide accurate signals for zoned air control.

[0004] A vehicle ventilation method is provided, particularly concerning improving ventilation efficiency to enhance passenger comfort. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention provides a vehicle ventilation method, the purpose of which is to improve ventilation efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a vehicle ventilation method, comprising: The vehicle interior lighting area and light intensity signals are acquired by multiple light sensing units distributed in different areas of the vehicle. The central controller unit module receives the illumination area and illumination intensity signals, and outputs speed control commands to the independent speed-regulating fans according to the illumination area and illumination intensity signals; An independent speed-regulating fan located in the air duct of the vehicle's air outlet receives the speed regulation command and adjusts its speed according to the command. The light sensing unit, central controller unit module, and independent speed-regulating fan are powered by a solar power module.

[0007] The vehicle ventilation control method further includes: The distribution signal of people inside the vehicle is obtained through position pressure sensors; The central controller unit module combines the illumination area and illumination intensity signals with the distribution signals of people inside the vehicle to output speed control commands to the independent speed-regulating fans in the corresponding areas of the people.

[0008] The step of outputting speed control commands to the independently speed-controlled fan based on the illumination area and illumination intensity signals specifically includes: The central controller unit module controls the independent speed-regulating fan corresponding to the area with high light intensity to run at high speed, and controls the independent speed-regulating fan corresponding to the area with low light intensity to run at low speed or turn off.

[0009] The vehicle ventilation control method further includes: The central controller unit module monitors the energy storage capacity of the solar power supply module. When the energy storage capacity is lower than a preset threshold, it reduces the power of each of the independent speed-regulating fans.

[0010] The vehicle ventilation control method further includes: When the vehicle is locked, the central controller unit module uses the solar power module to supply power and control the independent speed-regulating fan to run at low speed.

[0011] The present invention also provides a vehicle ventilation system, comprising: Solar power module; A regional illumination detection module, which includes multiple light sensing units distributed in different areas of the vehicle; An air outlet regulation module, comprising multiple independently speed-controlled fans, each fan being positioned within the air duct of the vehicle's air outlet; and The central controller unit module is electrically connected to the area illumination detection module, the solar power supply module, and the air outlet adjustment module, respectively. The central controller unit module receives the signal from the light sensing unit and outputs speed adjustment commands to the independent speed-regulating fan.

[0012] The plurality of light sensing units are at least divided into a left light detection channel, a right light detection channel, a front windshield light detection channel, and a rear windshield light detection channel.

[0013] The solar power supply module includes a photoelectric converter, an energy storage component, and a voltage regulator, and the photoelectric converter and the energy storage component are both electrically connected to the voltage regulator. The photoelectric conversion element has a flexible or semi-flexible structure and is disposed on the roof, the surface of the panoramic sunroof, or the area of ​​the windshield sun visor.

[0014] The energy storage component is an energy storage capacitor or a lithium battery.

[0015] The vehicle ventilation system also includes a position pressure sensor, which is electrically connected to the central controller unit module.

[0016] The present invention also provides a vehicle including the aforementioned vehicle ventilation system.

Detailed Implementation

[0019] To make the technical problems, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, in the following embodiments, the terms "first," "second," "third," "fourth," "fifth," and "sixth" do not represent an absolute distinction in structure and / or function, nor do they represent a sequential execution order, but are merely for the convenience of description.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] The technical concept of this invention includes: With the continuous advancement of automotive intelligence and new energy, cabin comfort and energy efficiency have become important indicators for measuring vehicle performance. As a key component in regulating the cabin microclimate, the performance of the vehicle ventilation system directly affects the actual experience of drivers and passengers. However, existing vehicle ventilation systems still have many shortcomings in terms of refined control and energy saving, mainly reflected in the following aspects: First, the air control method is singular, unable to achieve accurate zoned adjustment. Traditional vehicle air conditioning or ventilation systems mostly adopt an overall air volume control mode, which can only adjust the total air volume of the entire system, and cannot individually adjust the air volume of corresponding locations according to the specific areas exposed to sunlight. In actual driving or parking scenarios, sunlight often only illuminates local areas inside the vehicle, resulting in higher temperatures in the illuminated areas and more suitable temperatures in the un-illuminated areas, easily leading to the phenomenon of "local overheating and local undercooling," reducing driving and passenger comfort. At the same time, the high air volume operation used to balance the overall temperature also causes unnecessary energy consumption. Second, the integration of solar energy applications with ventilation systems is not deep enough. Existing vehicle-mounted solar panels are mostly limited to replenishing the vehicle's main battery or driving a single ventilation fan for overall vehicle ventilation, failing to achieve zoned airflow control. Furthermore, the lack of coordination between solar power supply and sunlight sensing systems prevents dynamic adjustment of ventilation power based on sunlight conditions, resulting in limited energy savings. This is particularly problematic for new energy vehicles, where traditional ventilation systems directly consume battery power, significantly impacting driving range with prolonged operation. Thirdly, sunlight sensors have limited functionality. Existing vehicle-mounted sunlight sensors primarily detect overall sunlight intensity to trigger automatic air conditioning activation or adjust total airflow, but lack spatial area recognition capabilities, failing to accurately determine the specific location of sunlight and thus providing insufficient signal support for zoned airflow control. Fourthly, their structural design is flawed, leading to poor adaptability. Existing vehicle ventilation fans are often single-piece structures, bulky and requiring modifications to the original vehicle's air duct structure during installation, making construction difficult and hindering independent control of individual air outlets. Simultaneously, the installation method of the solar panels is not adequately adapted to the curved surface of the vehicle body, resulting in low solar energy utilization and impacting the overall energy-saving performance of the system.

[0023] In existing technologies, a method and device for intelligent ventilation during parking are disclosed. This method involves installing a fan on the roof, detecting the interior temperature and rainfall, and activating front and rear fans to circulate air inside and outside the vehicle when thresholds are reached. However, this solution cannot direct airflow to the passenger area, resulting in energy waste. Furthermore, existing technologies also disclose a method for controlling air conditioning vents by collecting light intensity and infrared imaging signals from different passenger areas. However, this method does not incorporate solar panels for energy saving, and its vent fans cannot be adjusted according to the actual needs of the passengers. The technical solution of this invention is as follows: Firstly, such as Figures 1 to 4As shown, an embodiment of the present invention provides a vehicle ventilation system, including: Solar power module; The area illumination detection module 100 includes multiple light sensing units distributed in different areas of the vehicle; An air outlet regulating module 300 includes multiple independently speed-regulating fans C02, each fan C02 being disposed within an air duct C03 at the vehicle's air outlet; and The central controller unit module 400 is electrically connected to the area light detection module 100, the solar power supply module, and the air outlet adjustment module 300, respectively. The central controller unit module 400 receives signals from the light sensing unit and outputs speed adjustment commands to the independent speed-regulating fan C02.

[0024] Specifically, the vehicle ventilation system provided in this invention aims to solve the technical problems of existing vehicle ventilation systems, such as the inability to perform zoned airflow control, high energy consumption, and insufficient integration of solar energy application with zoned airflow control. The vehicle ventilation system of this invention achieves independent speed adjustment of the air outlet fans through zoned sunlight sensing, allowing air to be delivered to corresponding sunlight areas, improving ventilation, solving the problem of large local temperature differences, and enhancing driving comfort. Furthermore, it employs an independent power supply module 200 and is equipped with an energy storage component S02, utilizing solar energy for independent power supply without consuming the vehicle's power battery, significantly reducing energy consumption and thus extending the vehicle's driving range.

[0025] In embodiments of the present invention, such as Figure 1 As shown, the solar power module is the energy source for the entire system, providing stable operating power to the area illumination detection module 100, the central controller unit module 400, and the independent speed-regulating fan C02, enabling them to operate independently of the vehicle's main power supply or in conjunction with the vehicle's main power supply to reduce overall vehicle energy consumption. The solar power module includes a photoelectric converter S01, an energy storage component S02, and a voltage regulator S03. Both the photoelectric converter S01 and the energy storage component S02 are electrically connected to the voltage regulator S03. Specifically, the photoelectric converter S01 is installed on the vehicle and converts the received solar radiation energy into electrical energy.

[0026] Furthermore, the photoelectric conversion component S01 has a flexible or semi-flexible structure, allowing it to be installed conformally to the curved surface of the vehicle body. The photoelectric conversion component S01 is a solar panel, and its installation location is preferably chosen on the roof, the surface of the panoramic sunroof, or the area of ​​the windshield sun visor. These areas receive the most sunlight during daily vehicle use and parking, ensuring that the photoelectric conversion component S01 absorbs sunlight to the maximum extent and improves photoelectric conversion efficiency.

[0027] In this embodiment of the invention, the power of the photoelectric converter S01 is designed to match the total power of the independent speed-regulating fan C02 and the energy storage requirements, ensuring that it can directly provide sufficient driving power to the system when there is sufficient sunlight. However, since the intensity of sunlight is greatly affected by weather, time, and environmental shading, the power output of the photoelectric converter S01 often fluctuates. Therefore, an energy storage component S02 is provided in the system. The energy storage component S02 is connected to the photoelectric converter S01 and is used to store the excess power converted by the photoelectric converter S01. When there is sufficient sunlight and the system power consumption is low, the excess power is stored in the energy storage component S02; when there is insufficient sunlight or the system enters high-load operation, the energy storage component S02 releases power to maintain the normal operation of the system. In this embodiment of the invention, the energy storage component S02 can be an energy storage capacitor or a small-capacity lithium battery. Energy storage capacitors have the advantages of fast charging and discharging speed and long life, and are suitable for frequent charge and discharge cycles; small-capacity lithium batteries have higher energy density and can provide longer-lasting power support. In practice, the choice can be made based on the vehicle's actual space and energy consumption requirements.

[0028] In this embodiment of the invention, the voltage regulator S03 is a voltage-stabilizing circuit connected between the photoelectric converter S01, the energy storage component S02, and the system load. The system load includes the area illumination detection module 100, the central controller unit module 400, and the independent speed-regulating fan C02. The function of the voltage regulator S03 is to convert the unstable electrical energy output from the photoelectric converter S01 or the electrical energy output from the energy storage component S02 into a stable DC voltage. This stable voltage can adapt to the operating voltage requirements of the independent speed-regulating fan C02 and the central controller unit module 400. By setting up the voltage regulator S03, damage to electronic components caused by voltage fluctuations is avoided, ensuring the stable operation of each module under complex lighting conditions.

[0029] In this embodiment of the invention, the area illumination detection module 100 is used to identify the sunlight exposure in different areas inside the vehicle, thereby providing corresponding control signals to the central controller unit module 400. For example... Figure 2 As shown, the area illumination detection module 100 mainly includes multiple light sensing units distributed in different areas of the vehicle. These light sensing units employ a multi-channel photosensitive sensor array structure. To achieve high-precision identification of the illumination area inside the vehicle, the multiple light sensing units are divided into at least a left-side illumination detection channel, a right-side illumination detection channel, a front windshield illumination detection channel, and a rear windshield illumination detection channel. Through this multi-channel array arrangement, the system possesses direction recognition capabilities, accurately determining whether sunlight enters the vehicle from the front, rear, left, or right side.

[0030] like Figure 2As shown, the left-side light detection channel consists of light-sensing units arranged in the left-side area of ​​the vehicle. Specifically, the left-side light detection channel includes a second light-sensing unit A02 located on the left-side A-pillar and a fourth light-sensing unit A04 located on the left-side C-pillar. These light-sensing units work together to detect sunlight entering through the left-side window of the vehicle. When sunlight shines from the left, the light-sensing units in the left-side area will detect a higher light intensity, while the light-sensing units in the right-side area will detect a relatively lower light intensity. By comparing the signal differences between the left and right light-sensing units, the system can accurately determine that the sunlight is coming from the left.

[0031] like Figure 2 As shown, the right-side illumination detection channel consists of light-sensing units arranged in the right-side area of ​​the vehicle. Specifically, the right-side illumination detection channel includes a first light-sensing unit A01 located on the right-side A-pillar and a third light-sensing unit A03 located on the right-side C-pillar. These light-sensing units work together to detect sunlight entering through the right-side window of the vehicle. When sunlight shines from the right, the light-sensing units in the right-side area will detect a higher light intensity, while the light-sensing units in the left-side area will detect a relatively lower light intensity. By comparing the signal differences between the left and right light-sensing units, the system can accurately determine that the sunlight is coming from the right.

[0032] like Figure 2 As shown, the windshield illumination detection channel consists of light sensing units arranged in the windshield area of ​​the vehicle. Specifically, the windshield illumination detection channel includes a fifth light sensing unit A05 located on the dashboard 600, capable of detecting sunlight entering from the windshield. When sunlight shines from the front, the light sensing units in the front area will detect higher light intensity, while the light sensing units in the rear area will detect relatively lower light intensity. By comparing the signal differences between the front and rear light sensing units, the system can accurately determine that the sunlight is coming from the front.

[0033] like Figure 2 As shown, the rear window light detection channel consists of light sensing units arranged in the rear windshield area of ​​the vehicle. Specifically, the rear window light detection channel includes a sixth light sensing unit A06 located at the rear of the roof, capable of detecting sunlight entering from the rear windshield. When sunlight shines from behind, the light sensing units in the rear window area will detect a higher light intensity, while the light sensing units in the front area will detect a relatively lower light intensity. By comparing the signal differences between the front and rear light sensing units, the system can accurately determine that the sunlight is coming from behind.

[0034] In this embodiment of the invention, the light sensing unit is installed in an area that does not obstruct the driver's field of vision and can comprehensively detect the interior lighting. For example, the light sensing units are distributed on the dashboard 600, the roof, both sides of the A-pillars, and both sides of the C-pillars. This distribution method can capture light entering the vehicle through the window glass from multiple angles, detecting not only light intensity but also the specific location and duration of sunlight exposure. The light sensing unit converts the detected light location, light intensity, and duration of exposure into electrical signals in real time. To achieve efficient signal transmission, the area lighting detection module 100 communicates with the central controller unit module 400 via a CAN bus or LIN bus. The CAN bus or LIN bus has high anti-interference capability and real-time performance, ensuring that the lighting signal is stably and quickly transmitted to the central controller unit module 400 in the complex automotive electromagnetic environment.

[0035] The central controller unit module 400, acting as the brain of the vehicle's ventilation system, is responsible for data processing and command issuance. The central controller unit module 400 is electrically connected to the area illumination detection module 100, the solar power supply module, and the air outlet adjustment module 300. In terms of signal acquisition, the central controller unit module 400 receives signals from the light sensing unit in the area illumination detection module 100, indicating the light position, light intensity, and illumination duration. Simultaneously, to further improve the targeted nature of ventilation and the comfort of occupants, such as... Figure 2 As shown, the vehicle ventilation system of this embodiment of the invention also includes a position pressure sensor, which is electrically connected to the central controller unit module 400. The position pressure sensor is typically installed inside the vehicle seat to identify the distribution area of ​​occupants. The position pressure sensor also transmits the occupant distribution signal to the central controller unit module 400 via a CAN bus or LIN bus.

[0036] In terms of data processing and command output, the central controller unit module 400, based on its built-in control strategy, comprehensively analyzes the light intensity signal and the personnel distribution signal to determine the specific needs of the high-temperature areas and personnel locations within the vehicle. Subsequently, the central controller unit module 400 outputs pulse width modulation (PWM) speed control commands to the corresponding independent speed-regulating fans C02. Through the precisely output PWM signals, the central controller unit module 400 can independently control the speed of each independent speed-regulating fan C02, realizing the airflow control logic that directs airflow towards the sunlit areas, thereby improving ventilation and ultimately enhancing passenger comfort.

[0037] In this embodiment of the invention, the air outlet adjustment module 300 is the system's execution component, such as... Figure 1 and Figure 3As shown, the air outlet regulating module 300 includes multiple independently speed-controlled fans C02, each of which is an electric fan driven by a motor. The independently speed-controlled fans C02 are housed within the air duct C03 of the vehicle's air outlet. During installation, the independently speed-controlled fans C02 are positioned between the blades of the vehicle's air outlet and the main air conditioning duct C03. To avoid affecting the normal operation of the original vehicle's air outlet and without damaging or altering the structure of the original air duct C03, the outer diameter of the independently speed-controlled fans C02 matches the inner diameter of the air duct C03, achieving an embedded installation. Furthermore, the independently speed-controlled fans C02 are fixed inside the air duct C03 by mounting brackets C04. Multiple mounting brackets C04 are provided to ensure stability even under vibration conditions during vehicle operation.

[0038] Each independently speed-regulating fan C02 can independently respond to the adjustment commands of the central controller unit module 400, achieving stepless speed regulation from 0-100% to meet the airflow needs of different users. In actual operation, the air outlet regulation module 300 has two working states: one is to work in conjunction with the original vehicle air conditioning system. When the original vehicle air conditioning is on, the independently speed-regulating fan C02 can operate as a booster fan, increasing the speed to accelerate the airflow in the corresponding area, thereby pressurizing the airflow and rapidly reducing the temperature in that area; the other is to operate independently. When the original vehicle air conditioning is off, such as when the vehicle is parked or to further conserve the vehicle's power battery, the independently speed-regulating fan C02 can operate independently powered by electricity provided by the solar power module, directly drawing in air from outside or inside the vehicle for circulation, achieving ventilation and cooling.

[0039] In addition, the central controller unit module 400 also monitors the power status of the energy storage component S02 in the solar power module in real time, so as to automatically adjust the system operation strategy when the power is insufficient, and ensure the continuous and stable operation of the vehicle ventilation system.

[0040] Secondly, such as Figure 4 As shown, based on the vehicle ventilation system provided in the above embodiments, this invention provides a vehicle ventilation method, including the following steps: S1. Acquire the light area and light intensity signal inside the vehicle through multiple light sensing units distributed in different areas of the vehicle; S2, the central controller unit module 400 receives the illumination area and illumination intensity signals, and outputs speed control commands to the independent speed-regulating fan C02 according to the illumination area and illumination intensity signals; S3. The independent speed-regulating fan C02 located in the air duct C03 at the vehicle's air outlet receives the speed regulation command and adjusts the speed according to the speed regulation command.

[0041] Among them, such as Figure 1As shown, the light sensing unit, the central controller unit module 400, and the independent speed-regulating fan C02 are powered by a solar power module.

[0042] Specifically, in step S1 above, when the vehicle starts or sunlight reaches a preset intensity, the components of the vehicle's ventilation system automatically start. The area light detection module 100, the solar power supply module, and the central controller unit module 400 are simultaneously powered on, while the independent speed-regulating fan C02 is in standby mode.

[0043] At this time, multiple light sensing units distributed in different areas of the vehicle acquire signals of the illuminated area and light intensity inside the vehicle. The light sensing units convert the detected light intensity, location, and duration into electrical signals, which are then transmitted to the central controller unit module 400 via the CAN bus or LIN bus.

[0044] The central controller unit module 400 has a built-in control strategy. In step S2 above, it outputs a speed control command to the independent speed-regulating fan C02 based on the illumination area and illumination intensity signal, specifically including: The central controller unit module 400 controls the independent speed-regulating fan C02 corresponding to areas with high light intensity to run at high speed, thereby accelerating the cooling rate of these high-temperature areas. Simultaneously, it controls the independent speed-regulating fan C02 corresponding to areas with low light intensity to run at low speed or shut down, to avoid unnecessary heat transfer and energy waste. This control strategy ensures that cool air can be directly delivered to areas where people are located and which are exposed to direct sunlight.

[0045] In step S3 above, the independent speed-regulating fan C02 located in the air duct C03 at the vehicle's air outlet receives speed regulation commands from the central controller unit module 400 and adjusts its speed accordingly. Since each independent speed-regulating fan C02 receives commands independently, the airflow at each air outlet can be adjusted differently, reaching varying levels. If the original vehicle air conditioning is on, the independent speed-regulating fan C02 works in conjunction with the original air conditioning system to pressurize and deliver air, improving cooling efficiency. If the original vehicle air conditioning is off, the independent speed-regulating fan C02 operates independently using electricity provided by the solar power module, achieving ventilation and cooling, and improving passenger comfort.

[0046] The vehicle ventilation control method of this invention further includes: The distribution signal of the occupants inside the vehicle is obtained through a position pressure sensor; this signal is also transmitted to the central controller unit module 400. The central controller unit module 400 combines the illumination area and intensity signals with the distribution signals of people inside the vehicle to output speed control commands to the independent speed-regulating fan C02 in the corresponding area of ​​the person.

[0047] In this embodiment of the invention, in order to adapt to different usage scenarios and energy states, the central controller unit module 400 has multiple control modes, including automatic mode, energy-saving mode and parking ventilation mode.

[0048] In step S3 above, when the control mode is automatic, the central controller unit module 400 receives real-time illumination information from the zone illumination detection module and personnel distribution information from the position pressure sensor, automatically determines the high-temperature zone and personnel location, and automatically outputs a PWM speed control signal to control the corresponding independent speed-regulating fan C02 to execute the corresponding speed. Specifically, when the illumination intensity is greater than 500W / m², 2 When the light intensity is less than 500W / m, the central controller unit module 400 controls the corresponding area's miniature independent speed-regulating fan C02 to run at a high speed of 4m / s to accelerate cooling; when the light intensity is less than 500W / m 2 When the system is in operation, the corresponding micro independent speed-regulating fan C02 operates at a low speed of 1-3m / s or shuts off to avoid wasting energy. This controls the airflow to the sunlit area, improving ventilation and thus enhancing passenger comfort. In this mode, the system operates fully automatically without manual intervention, maximizing driving and riding comfort.

[0049] In step S3 above, when the control mode is energy-saving mode, since the system relies on the solar power module for power, the power of the energy storage component S02 will gradually decrease when encountering continuous cloudy or rainy weather or insufficient sunlight. The central controller unit module 400 monitors the energy storage power of the solar power module in real time. When the energy storage power is lower than a preset threshold, the system automatically enters energy-saving mode, reducing the power of each independent speed-regulating fan C02. In energy-saving mode, the central controller unit module 400 automatically reduces the power of each independent speed-regulating fan C02, for example, by reducing the duty cycle of the PWM signal, prioritizing ventilation needs in areas with direct sunlight and passengers, and shutting down or running fans in other areas at very low speeds. This mode ensures that the system can still maintain the comfort of the main areas inside the vehicle when power is limited, and avoids sudden system shutdown due to power depletion.

[0050] The vehicle ventilation control method of this invention further includes: When the vehicle is locked, the central controller unit module 400 uses the solar power module to supply power and control the independent speed-regulating fan C02 to run at low speed.

[0051] In step S3 above, when the control mode is parking ventilation mode, after the occupants leave the vehicle while it is locked, the interior temperature rises sharply under direct sunlight, and harmful gases such as formaldehyde are released from materials like plastics and leather. At this time, the system enters parking ventilation mode. While the vehicle is locked, the central controller unit module 400 uses a solar power module to control the independent speed-regulating fan CO2 to run at a low speed of 1-2 m / s. Since it does not consume the vehicle's battery power, this mode can operate for extended periods, allowing air circulation between the vehicle interior and exterior, effectively reducing the high temperature inside the vehicle after prolonged exposure to sunlight and minimizing the release of harmful gases like formaldehyde. When the occupants return to the vehicle, they will enjoy a more comfortable and healthier cabin environment, while also reducing the cooling load on the air conditioning system after the vehicle is started.

[0052] When the vehicle is turned off and there is no sunlight, and the energy stored in the solar power module is depleted to the minimum protection voltage, the central controller unit module 400 automatically shuts down all modules and stops operating to protect the energy storage component S02 from over-discharge damage.

[0053] The vehicle ventilation system and method of this invention have the following advantages: First, it achieves precise control of zoned sunlight perception and airflow. By employing a multi-channel photosensitive sensor array as the zoned sunlight detection module 100, it can accurately and effectively identify the specific areas, intensity, and duration of sunlight exposure inside the vehicle. Combined with the occupant distribution signal obtained from the position pressure sensor, the central controller unit module 400 can control the independent speed-regulating fans C02 in the corresponding areas to perform differentiated speed adjustments. This airflow control logic, which directs airflow towards the sunlit areas, can solve the problems of large local temperature differences and poor comfort inside the vehicle, resulting in high utilization of cool air, improved ventilation, and ultimately, enhanced passenger comfort. Secondly, a solar power module is installed to achieve independent power supply, which can significantly reduce energy consumption. By installing flexible or semi-flexible photovoltaic conversion components S01 in high-sunlight areas such as the roof, together with energy storage components S02 and voltage regulators S03, a power supply system independent of the vehicle's main power supply is constructed. In automatic mode, energy-saving mode, and even parking ventilation mode, the system can prioritize or fully utilize solar power without consuming the vehicle's power battery. This not only solves the technical problem of high energy consumption in traditional ventilation systems affecting driving range, but also achieves green and energy-saving cabin environment management.

[0054] Third, the structural design is reasonable, with strong adaptability and compatibility. The independent speed-regulating fan C02 in the air outlet adjustment module 300 is cleverly designed as an embedded structure, directly installed in the air duct C03 of the vehicle's air outlet. Its outer diameter matches the inner diameter of the air duct C03, and it is located between the air outlet blades and the main air duct C03. This design does not require modification to the original vehicle air duct C03 structure, does not affect the normal use of the original vehicle's air outlet, has low installation difficulty, and is compatible with various vehicle models.

[0055] Fourth, it can intelligently switch between multiple modes to meet the needs of various scenarios. The central controller unit module 400 has built-in multiple control modes, such as automatic, energy-saving, and parking ventilation, which can intelligently switch according to vehicle status, lighting conditions, and battery level. Especially in parking ventilation mode, it uses solar energy to drive the fan to run at low speed, lowering the interior temperature and expelling harmful gases in advance, greatly improving the user's experience when getting into the car. The system also supports coordinated pressurization and air supply with the original vehicle air conditioning or independent operation, offering rich functionality and strong practicality.

[0056] Thirdly, embodiments of the present invention also provide a vehicle including a vehicle ventilation system with the above-described structure. The vehicle is a new energy vehicle, and this vehicle ventilation system can be referred to... Figures 1 to 4 Further details will not be elaborated here. Since the vehicle of the present invention includes the vehicle ventilation system described in the above embodiments, it possesses all the advantages of the aforementioned vehicle ventilation system.

[0057] In practical applications, this vehicle can not only use solar energy or a cooperating onboard power source to drive an independently speed-regulating fan C02 for directional cooling during driving, based on the direction of sunlight and the distribution of passenger seating, thus improving ventilation and enhancing passenger comfort; it can also collect solar energy using photoelectric conversion components S01 on the vehicle body surface when parked, independently driving the ventilation system without starting the vehicle engine or consuming power from the battery, thereby achieving cooling and ventilation inside the vehicle.

[0058] By applying the aforementioned vehicle ventilation system, the vehicle not only improves driving comfort but also significantly reduces overall vehicle energy consumption, with energy savings reaching 30% to 60%, effectively extending the driving range of new energy vehicles. Furthermore, because the independent speed-regulating fan C02 adopts an embedded design and is compatible with the original vehicle's air duct C03, the system has a simple structure, requires no major modifications to the original vehicle structure, is low-cost, easy to mass-produce, and has extremely high market application value.
