[0002] With the continuous development of vehicle technology, passengers' demands for the driving and riding experience are also constantly increasing. For example, during actual vehicle operation, the intensity of sunlight on different areas of the vehicle changes due to the constantly changing direction of the vehicle and the direction of sunlight hitting the vehicle.

[0025] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] The following description sets forth many specific details to provide a full understanding of this application. The described embodiments are only some, not all, of the embodiments of this application.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0028] It should be further noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0029] In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and drawings of this application are used to distinguish similar objects, not to describe a specific order or sequence.

[0030] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0031] With the continuous development of vehicle technology, passengers' demands for the driving and riding experience are also constantly increasing. For example, during actual vehicle operation, the intensity of sunlight on different areas of the vehicle changes due to the constantly changing direction of the vehicle and the direction of sunlight hitting the vehicle.

[0032] If a certain area of ​​the vehicle is exposed to strong sunlight, the interior temperature will rise sharply, which will seriously affect the passenger's driving and riding experience.

[0033] Therefore, most vehicles are now equipped with sunlight sensors, whose photosensitive elements are used to collect the intensity of sunlight on the left and right sides of the vehicle. For example... Figure 1 The diagram shown illustrates the characteristics of a sunlight sensor. Figure 1 To understand the meaning of the curve, we need to first explain some technical terms:

[0034] In this embodiment, the driving deviation angle is the angle between the vehicle's driving direction and the projection of sunlight onto the ground plane. The solar altitude angle is the angle between sunlight and the projection of sunlight onto the ground plane.

[0035] exist Figure 1 In the coordinate system of the curve, the vertical axis represents the sunlight intensity value, and the horizontal axis represents the driving yaw angle. Assuming the solar altitude angle remains constant at 60°, the vehicle rotates one full circle in place, and the left and right sensors collect sunlight intensity values ​​at different driving yaw angles, resulting in... Figure 1 The data shows the changes in sunlight intensity (series 1 and series 2, where series 1 represents data collected by the right-side sunlight sensor and series 2 represents data collected by the left-side sunlight sensor). When the vehicle is directly facing the sun, the vehicle's directional deviation angle is 0°, and both sunlight sensors collect data at 85%. When L = 40°, the right-side sunlight sensor shows the lowest light intensity; when L = -40°, the left-side sunlight sensor shows the lowest light intensity.

[0036] Therefore, it can be concluded that when a vehicle travels in different directions, even if the sunlight intensity is the same, the sunlight intensity value collected by the sunlight sensor varies greatly. When the vehicle is traveling in different directions (such as with its back to the sun), the sunlight intensity value is very low, but the rear of the vehicle and the roof of the vehicle are still heated, resulting in a relatively large heat load on the vehicle. If the sunlight compensation is low when calibrating the vehicle's temperature control system, the interior of the vehicle will be too hot or too cold, causing a poor driving and riding experience for the passengers.

[0037] To solve the above problems, please refer to... Figure 2This application provides a vehicle temperature adjustment method. The vehicle temperature adjustment method is applied to a vehicle. The vehicle can be a gasoline-powered vehicle or a new energy vehicle; this application does not limit the specific type of vehicle.

[0038] The vehicle temperature adjustment method includes the following steps:

[0039] Step 101: Based on the vehicle's location and the current time, obtain the solar altitude angle and driving deviation angle.

[0040] In this embodiment, as Figure 3 As shown, the arrow points in the direction the vehicle is traveling. The line connecting the coordinate center and the sun represents the projection of sunlight onto the horizon. The yaw angle is denoted as L. Please refer to [further details needed]. Figure 4 Let H denote the solar altitude angle. Based on common sense, we know that the solar altitude angle is at its maximum at noon and at its minimum at sunrise or sunset.

[0041] Because the vehicle's location and the current time are constantly changing, the solar altitude angle and driving yaw angle are also constantly changing. Therefore, it is necessary to obtain the specific real-time values ​​of the solar altitude angle and driving yaw angle based on the vehicle's location and the current time.

[0042] In this embodiment, the driving deviation angle can be obtained through the cloud network. For example, the cloud network can calculate the driving deviation angle by combining the Global Positioning System (GPS) and astronomical algorithms or by using visual sensors and image recognition.

[0043] The combination of GPS and astronomical algorithms primarily utilizes GPS to obtain the vehicle's precise location (e.g., longitude, latitude, and time). Based on astronomical algorithms, and combining the current time, geographical location, and Earth's rotation and revolution parameters, the sun's position in the sky can be calculated, thus determining the direction of the sun's rays projected onto the horizon. This information, combined with the vehicle's driving direction information (obtained through GPS track estimation or other sensors), is used to calculate the driving yaw angle through vector operations and other methods.

[0044] The primary method using visual sensors and image recognition involves mounting cameras on vehicles to capture images including the sky and horizon. Image recognition technology then identifies the position of the sun and the horizon within the image. Based on the camera's mounting parameters (such as viewing angle and tilt angle) and the relative position of the sun and horizon in the image, the direction of the sunlight's projection onto the ground plane is calculated. Simultaneously, by combining this with information about the vehicle's direction of travel (e.g., determining the vehicle's direction of travel on the road through lane line recognition), the yaw angle can be calculated.

[0045] In other embodiments, the driving deviation angle can also be calculated based on a solar position sensor or an electronic compass and solar altitude angle measurement, and this application does not limit the calculation method of the driving deviation angle.

[0046] The solar altitude angle can be calculated using the following formula:

[0047] H=90°-|ab|

[0048] Where a is the latitude of the vehicle's location and b is the latitude of the subsolar point.

[0049] Step 102: Obtain the vehicle side area and light intensity data.

[0050] In this embodiment, the vehicle side area is the sum of the areas of multiple different regions of the vehicle, and the light intensity data characterizes the light intensity of sunlight irradiating the vehicle.

[0051] In this embodiment, the vehicle's various regions include a front region, a rear region, a left region, a right region, and a top region. Specifically, the front region is the area containing the windshield, the rear region is the area containing the rear windshield, the left region is the area containing the left front and left rear windows, the right region is the area containing the right front and right rear windows, and the top region is the area containing the roof.

[0052] Furthermore, in one embodiment, the vehicle side area includes a front side area and a rear side area. In another embodiment, the vehicle side area includes a left side area, a right side area, and a top surface area. In yet another embodiment, the vehicle side area includes a front side area, a rear side area, a left side area, a right side area, and a top surface area. Wherein, the front side area is the area of ​​the front region; the rear side area is the area of ​​the rear region; the left side area is the area of ​​the left side region; the right side area is the area of ​​the right side region; and the top surface area is the area of ​​the top region.

[0053] In this embodiment, the vehicle side area, including the front side area, rear side area, left side area, right side area, and top surface area, is used as an example for explanation.

[0054] In this embodiment, light intensity data can be collected by a photoelectric sensor installed on the vehicle, such as a sunlight sensor. In other embodiments, light intensity data can also be obtained by a solar intensity meter or a light intensity measuring instrument. This application does not limit the method of collecting light intensity data.

[0055] Step 103: Based on the vehicle side area, solar altitude angle, and driving deflection angle, obtain the direct sunlight rate.

[0056] In this embodiment, the direct sunlight exposure rate characterizes the magnitude of the heat load generated by the vehicle being irradiated by sunlight. To obtain the direct sunlight exposure rate, the direct sunlight exposure area needs to be calculated first. The direct sunlight exposure area is the sum of the projected areas of multiple sides of the vehicle when sunlight shines directly on each side of the vehicle. The projection direction is the direction that is perpendicular to the driving angle of the projection of the sunlight on the ground plane.

[0057] Specifically, the area directly illuminated by sunlight is obtained based on the vehicle's side area, the solar altitude angle, and the driving yaw angle; the quotient of the vehicle's side area and the area directly illuminated by sunlight is taken as the direct sunlight rate. In one embodiment, the area directly illuminated by sunlight includes the sum of the front and rear direct sunlight areas. In another embodiment, the area directly illuminated by sunlight includes the sum of the left, right, and top direct sunlight areas. In yet another embodiment, the area directly illuminated by sunlight includes the sum of the front, rear, left, right, and top direct sunlight areas. Among them, the front direct-sunlight area is the projected area of ​​the front region in the projection direction when the sun shines directly on the front region. Similarly, the rear direct-sunlight area is the projected area of ​​the rear region in the projection direction when the sun shines directly on the rear region. The left direct-sunlight area is the projected area of ​​the left region in the projection direction when the sun shines directly on the left region. The right direct-sunlight area is the projected area of ​​the right region in the projection direction when the sun shines directly on the right region. The top direct-sunlight area is the projected area of ​​the top region in the projection direction when the sun shines directly on the top region.

[0058] In this embodiment, the example is taken as the sum of the direct light area, including the front direct light area, the rear direct light area, the left direct light area, the right direct light area, and the top direct light area.

[0059] The following is a detailed calculation process for the direct sunlight area on the front, rear, left, right, and top surfaces.

[0060] (1) The calculation steps for the front direct radiation area include:

[0061] Obtain the first tilt angle, where the first tilt angle is the angle between the area containing the windshield and the ground plane. Please also consider... Figure 4 Let the first tilt angle be denoted as α. Based on the front area, the first tilt angle, the solar altitude angle, and the driving deflection angle, the front direct sunlight area is obtained.

[0062] In this embodiment, The product of is the front direct area, where S1 is the front area.

[0063] (2) The calculation steps for the direct area behind the object include:

[0064] Obtain the second tilt angle, which is the angle between the area containing the rear windshield and the ground plane. Based on the rear area, the second tilt angle, the solar altitude angle, and the driving deflection angle, obtain the rear direct sunlight area.

[0065] In this embodiment, The product of is the rear direct area, where S2 is the rear area and β is the second tilt angle.

[0066] (3) The calculation steps for the area directly exposed on the left side include:

[0067] The area directly exposed on the left side is obtained based on the area on the left, the solar altitude angle, and the driving deflection angle.

[0068] In this embodiment, The product of is the area directly irradiated on the left, where S3 is the area on the left.

[0069] (4) The calculation steps for the right-side direct sunlight area include:

[0070] The right-side direct sunlight area is obtained based on the area on the right side, the solar altitude angle, and the driving deflection angle.

[0071] In this embodiment, The product of is the area directly irradiated on the right, where S4 is the area on the right.

[0072] (5) The calculation steps for the direct sunlight area on the top surface include:

[0073] The direct sunlight area of ​​the top surface is obtained based on the top surface area and the solar altitude angle.

[0074] In this embodiment, The product of is the area directly radiated on the right, where S5 is the area of ​​the top surface.

[0075] In this embodiment, + + + + The sum of these sums is taken as the area directly illuminated by the light. The quotient of the area directly illuminated by the light and the sum of S1+S2+S3+S4+S5 is taken as the directness of the light.

[0076] In this embodiment, a higher light directness indicates a larger area of ​​the vehicle directly exposed to sunlight, a greater area of ​​the vehicle heated by the sun, and a greater heat load generated by the sun's radiation. Conversely, a lower light directness indicates a smaller area of ​​the vehicle directly exposed to sunlight, a smaller area of ​​the vehicle heated by the sun, and a smaller heat load generated by the sun's radiation.

[0077] Step 104: Correct the light intensity data using the light directness to obtain the corrected light intensity data.

[0078] The illuminance data is corrected using the light directivity to obtain accurate illuminance data. This allows for subsequent adjustments to the vehicle's climate control system based on the corrected illuminance data, thereby improving the passenger's driving and riding experience. The specific correction process is described in detail in subsequent steps and will not be repeated here to avoid repetition.

[0079] Step 105: Based on the corrected light intensity data, adjust the operating data of the vehicle's interior temperature control system.

[0080] In some embodiments, the temperature control system can be an air conditioner, and the operating data of the temperature control system can include the air volume and the air temperature. In other embodiments, the temperature control system can also be a heating device or a cooling device, and the operating data of the temperature control system can also include the air outlet angle, etc. This application does not limit the type of temperature control system or the specific type of operating data.

[0081] In this embodiment, the ambient temperature of the vehicle is obtained, and the air outlet temperature and air outlet volume are adjusted based on the ambient temperature and the corrected light intensity data.

[0082] For adjustments to the airflow, please refer to Table 1:

[0083]

[0084] For adjusting the outlet air temperature, please refer to Table 2:

[0085]

[0086] Table 1 shows that when the ambient temperature of the vehicle is 10 degrees Celsius and the corrected illuminance is 200, the existing airflow needs to be increased by 3%. Table 2 shows that when the ambient temperature of the vehicle is 10 degrees Celsius and the corrected illuminance is 1000, the existing airflow temperature needs to be decreased by 1 degree Celsius.

[0087] It should be noted that the data in Tables 1 and 2 are for illustrative purposes only and do not limit the content of this application. Adjustment rules can be set according to the actual needs for adjusting the operating data. Furthermore, if the operating data includes data other than air volume and air temperature, corresponding adjustment rules can also be set for these other data.

[0088] Compared with related technologies, the embodiments of this application have at least the following advantages:

[0089] Based on the vehicle's location and current time, the accurate solar altitude angle and yaw angle can be obtained in real time for different vehicle positions. Then, using the vehicle's side area, solar altitude angle, and yaw angle, the direct sunlight intensity (RSI) can be calculated, accurately reflecting the heat load the vehicle receives from sunlight at its current location. A higher RSI indicates a higher heat load from sunlight, while a lower RSI indicates a lower heat load. Thus, by correcting the irradiance data based on RSI, the true irradiance of the vehicle can be obtained. Finally, the corrected irradiance data is used to adjust the vehicle's climate control system, thereby improving the passenger experience.

[0090] Please see Figure 5 , Figure 5 This is another schematic flowchart illustrating the vehicle temperature adjustment method provided in this application embodiment. This embodiment is a detailed description of step 104. The light intensity data includes a first light intensity and a second light intensity. The first light intensity is the light intensity of sunlight irradiating one side of the vehicle, and the second light intensity is the light intensity of sunlight irradiating the other side of the vehicle.

[0091] In this embodiment, two sunlight sensors (denoted as the first sensor and the second sensor) are installed on the top of the vehicle, and the first sensor and the second sensor are located on opposite sides of the top position of the central rearview mirror. The first sensor is used to collect the light intensity of sunlight shining on the left side of the vehicle (denoted as the first light intensity), and the second sensor is used to collect the light intensity of sunlight shining on the right side of the vehicle (denoted as the second light intensity).

[0092] In other embodiments, the two sunlight sensors may also be located on opposite sides of the skylight, with one sunlight sensor used to collect a first light intensity and the other used to collect a second light intensity. This application does not limit the specific location of the two sunlight sensors.

[0093] The specific steps for correcting illuminance data using ray directness to obtain corrected illuminance data include:

[0094] Step 201: Calculate the intensity difference between the first light intensity and the second light intensity.

[0095] In this embodiment, the intensity difference is the absolute value of the difference between the first light intensity and the second light intensity.

[0096] Step 212: If the intensity difference is greater than the preset difference, calculate the average intensity of the first light intensity and the second light intensity, as well as the light difference.

[0097] In this embodiment, the illumination difference is the difference between the first illumination intensity and the second illumination intensity. The system detects whether the intensity difference is greater than a preset difference. If the intensity difference is greater than the preset difference, the first illumination intensity is corrected based on the first illumination intensity, the second illumination intensity, and the directness of light, to obtain the third illumination intensity. The preset difference can be 200, 300, or 400; the specific value of the preset difference can be set according to the specific correction requirements.

[0098] If the intensity difference is greater than a preset difference, it indicates that the sunlight is hitting the vehicle from the side. To obtain accurate light intensity data, the first and second light intensities need to be corrected. The average intensity is (TL+TR) / 2, and the light difference is TL-TR.

[0099] Step 213: Correct the first illumination intensity based on the mean intensity, illumination difference, and direct illumination rate to obtain the third illumination intensity.

[0100] Furthermore, it is determined whether the first light intensity is greater than the second light intensity. When the first light intensity is greater than the second light intensity, it indicates that the sunlight is shining on the left side of the vehicle. The third light intensity is then obtained using Formula 1.

[0101] Formula 1:

[0102] Where TL is the first illuminance, TR is the second illuminance, γ is the direct irradiance, and TL1 is the third illuminance.

[0103] When the first light intensity is detected to be no greater than the second light intensity, it indicates that the sunlight is shining on the right side of the vehicle. The third light intensity is then obtained using Formula 2:

[0104] Formula 2:

[0105] In this way, the vehicle can obtain an accurate third light intensity regardless of whether the sunlight shines on it from the left or the right.

[0106] Step 214: Correct the second illumination intensity based on the mean intensity, illumination difference, and direct light intensity to obtain the fourth illumination intensity.

[0107] Similarly, when the first light intensity is detected to be greater than the second light intensity, the fourth light intensity is obtained using Formula 3:

[0108] Formula 3:

[0109] TR1 represents the fourth light intensity.

[0110] When the first light intensity is detected to be no greater than the second light intensity, the fourth light intensity is obtained using Formula 4:

[0111] Formula 4:

[0112] In this way, the fourth light intensity can be accurately obtained regardless of whether the sunlight shines on the vehicle from the left or the right.

[0113] Step 222: If the strength difference is not greater than the preset difference, check whether the driving deviation angle is greater than the preset deviation angle.

[0114] If the intensity difference is not greater than the preset difference, it indicates that the sunlight is shining on the vehicle from the front or the back. In order to obtain accurate light intensity data, the first light intensity and the second light intensity need to be corrected.

[0115] By detecting whether the driving deviation angle is greater than a preset deviation angle, it is determined whether the sunlight is shining on the side directly in front of the vehicle or on the rear of the vehicle. The preset deviation angle is 90 degrees.

[0116] Step 223: When the driving deviation angle is detected to be greater than the preset deviation angle, the first light intensity is corrected based on the first preset coefficient, the first light intensity, the second light intensity and the direct light intensity to obtain the fifth light intensity.

[0117] If the detected deviation angle is greater than the preset deviation angle, it indicates that sunlight is illuminating the rear of the vehicle. The fifth illuminance is obtained using the following formula 5:

[0118] Formula 5:

[0119] Wherein, K1 is the first preset coefficient, and the specific value of K1 can be set and changed according to the needs of the correction. This application does not limit the specific value of K1.

[0120] Step 224: Based on the second preset coefficient, the first light intensity, the second light intensity, and the direct light intensity, the second light intensity is corrected to obtain the sixth light intensity.

[0121] In this embodiment, the sixth illumination intensity is obtained using the following formula 6:

[0122] Formula 6:

[0123] K2 is the second preset coefficient. The specific value of K2 can be set and changed according to the needs of the correction. This application does not limit the specific value of K2.

[0124] It should be noted that the specific values ​​of the first and second preset coefficients can be adjusted according to the difference between the actual first and second light intensities and the revised fifth and sixth light intensities during the calibration process.

[0125] Step 233: If the detected driving deviation angle is not greater than the preset deviation angle, the first light intensity is used as the fifth light intensity, and the second light intensity is used as the sixth light intensity.

[0126] If the detected driving deviation angle is not greater than the preset deviation angle, it indicates that the sunlight is shining on the front side of the vehicle. Therefore, in this embodiment, the first light intensity can be directly used as the fifth light intensity, and the second light intensity can be used as the sixth light intensity.

[0127] Compared with related technologies, the embodiments of this application have at least the following advantages:

[0128] First, the difference between the first and second light intensities is checked to see if it exceeds a preset difference, thus determining whether the sunlight is shining on the side, front, or rear of the vehicle. If the sunlight is shining on the left side of the vehicle, the third and fourth light intensities are calculated using formulas 1 and 3. If the sunlight is shining on the right side of the vehicle, the third and fourth light intensities are calculated using formulas 2 and 4. If the sunlight is shining on the rear of the vehicle, the fifth and sixth light intensities are calculated using formulas 5 and 6. If the sunlight is shining on the front of the vehicle, the first light intensity is directly used as the fifth light intensity, and the second light intensity is used as the sixth light intensity. In this way, accurate corrected light intensity data can be obtained, which can be used to adjust the operating data of the temperature control system to improve the passenger's driving experience.
