[0002] With the continuous development of vehicle technology, passengers' requirements for vehicle driving experience are also increasing. For example, during the actual driving process of the vehicle, the direction of the vehicle and the direction of the sun's rays on the vehicle are constantly changing, so the intensity of the sun's rays on various areas of the vehicle also changes accordingly.

[0024] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the implementation methods of the present application and the features in the implementation methods can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present application. The described implementations are only part of the implementations of the present application, rather than all the implementations.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0027] It should be further noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0028] In this application, "at least one" means one or more, and "more" means two or more than two. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The terms "first", "second", "third", "fourth", etc. (if any) in the specification, claims and drawings of this application are used to distinguish similar objects, rather than to describe a specific order or sequence.

[0029] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0030] With the continuous development of vehicle technology, passengers' requirements for vehicle driving experience are also increasing. For example, during the actual driving process of the vehicle, the direction of the vehicle and the direction of the sun's rays on the vehicle are constantly changing, so the intensity of the sun's rays on various areas of the vehicle also changes accordingly.

[0031] At this time, if a certain area of ​​the vehicle is exposed to strong sunlight, the temperature inside the vehicle will rise sharply, which will seriously affect the passengers' driving experience.

[0032] Based on this, most vehicles are currently equipped with sunlight sensors, the photosensitive elements of which are used to collect the sunlight intensity on the left and right sides of the vehicle. Figure 1 The following is a characteristic diagram of the sunlight sensor. Figure 1 The meaning of the middle curve requires some explanation of professional terms: In this embodiment, the driving deviation angle is the angle between the driving direction of the vehicle and the projection of the sun's rays on the ground plane. The solar altitude angle is the angle between the sun's rays and the projection of the sun's rays on the ground plane.

[0033] exist Figure 1 In the coordinates of the curve, the ordinate represents the sunlight intensity value, and the abscissa represents the driving deviation angle. Assuming that the solar altitude angle remains unchanged, that is, 60°, the vehicle rotates in place for one circle, and the left and right sensors collect the sunlight intensity values ​​under different driving deviation angles, and obtain Figure 1 The sunlight intensity variation curve in (i.e., series 1 and series 2, where series 1 is the data collected by the right sunlight sensor and series 2 is the data collected by the left sunlight sensor). When the vehicle is facing the sun, the vehicle's driving direction deflection angle is 0, and the data collected by the two sunlight sensors are both 85%; when L=40°, the light intensity displayed by the right sunlight sensor is the lowest; when L=-40°, the light intensity displayed by the left sunlight sensor is the lowest.

[0034] From this, we can conclude that when the vehicle is traveling in different directions, although the sunlight intensity is the same, the sunlight intensity values ​​collected by the sunlight sensor vary greatly. When the vehicle is traveling in different directions (for example, facing away from the sunlight), the sunlight intensity value is very low, but the back of the vehicle and the roof of the vehicle are still heated, and the thermal load of the vehicle is relatively large. If the sunlight compensation is low when calibrating the temperature control system in the vehicle, the interior of the vehicle will be hotter or colder, resulting in a poor driving experience for the passengers in the vehicle.

[0035] To solve the above problems, please refer to Figure 2, the embodiment of the present application provides a vehicle temperature adjustment method. The vehicle temperature adjustment method is applied to a vehicle. The vehicle can be a fuel vehicle or a new energy vehicle, and the present application does not limit the specific type of the vehicle.

[0036] The vehicle temperature adjustment method comprises the following steps: Step 101: Obtain the solar altitude angle and the driving direction angle according to the vehicle's location and current time.

[0037] In this embodiment, if Figure 3 As shown in the figure, the direction of the arrow is the direction of the vehicle's travel, the line between the coordinate center and the sun represents the projection line of the sun's rays on the horizon, and the travel deviation angle is recorded as L. Figure 4 , and the solar altitude angle is recorded as H. Based on common sense, the solar altitude angle is the largest at 12 noon, and the solar altitude angle is the smallest at sunrise or sunset.

[0038] Since the location of the vehicle and the current time are constantly changing, the sun altitude angle and the driving deflection angle are also constantly changing. Therefore, it is necessary to obtain the specific values ​​of the real-time sun altitude angle and the driving deflection angle based on the location of the vehicle and the current time.

[0039] In this embodiment, the driving deviation angle can be obtained through the network cloud. For example, the network cloud can calculate the driving deviation angle by combining the global positioning system (GPS) and astronomical algorithms or by visual sensors and image recognition.

[0040] Among them, the combination of GPS and astronomical algorithms mainly uses GPS to obtain the precise location of the vehicle (for example, longitude, latitude, time and other information). According to the astronomical algorithm, combined with the current time, geographical location and the rotation and revolution parameters of the earth, the position of the sun in the sky can be calculated, and then the projection direction of the sun's rays on the ground plane can be obtained. Combined with the vehicle's driving direction information (which can be obtained through GPS track calculation or other sensors), the driving deviation angle is calculated through methods such as vector operations.

[0041] The main method of visual sensors and image recognition is to install a camera on the vehicle to capture images containing the sky and the horizon. Through image recognition technology, the position of the sun in the image and the position of the horizon are identified. According to the installation parameters of the camera (such as viewing angle, tilt angle, etc.) and the relative position relationship between the sun and the horizon in the image, the projection direction of the sun's rays on the ground plane is calculated. At the same time, combined with the vehicle's driving direction information (for example, determining the vehicle's driving direction on the road through lane line recognition), the driving deviation angle can be calculated.

[0042] In other embodiments, the driving deviation angle may also be calculated based on a sun position sensor or an electronic compass and sun altitude angle measurement, and the present application does not limit the calculation method of the driving deviation angle.

[0043] The solar altitude angle can be calculated using the following formula: H=90°-|ab| Among them, a is the latitude of the vehicle's location, and b is the latitude of the sun's direct point.

[0044] Step 102: Acquire vehicle side area and light intensity data of the vehicle.

[0045] In this embodiment, the side area of ​​the vehicle is the sum of the areas of multiple different regions of the vehicle, and the light intensity data represents the light intensity of the vehicle when it is exposed to sunlight.

[0046] In this embodiment, the multiple different areas of the vehicle include a front area, a rear area, a left area, a right area, and a top area. The front area is the area where the front windshield is located, the rear area is the area where the rear windshield is located, the left area is the area where the left front window and the left rear window are located, the right area is the area where the right front window and the right rear window are located, and the top area is the area where the roof is located.

[0047] Furthermore, in one embodiment, the side area of ​​the vehicle includes the front area and the rear area. In another embodiment, the side area of ​​the vehicle includes the left area, the right area, and the top area. In yet another embodiment, the side area of ​​the vehicle includes the front area, the rear area, the left area, the right area, and the top area. Among them, the front area is the area of ​​the front area; the rear area is the area of ​​the rear area; the left area is the area of ​​the left area; the right area is the area of ​​the right area; and the top area is the area of ​​the top area.

[0048] In this embodiment, the vehicle side area includes five areas: front side area, rear side area, left side area, right side area and top surface area.

[0049] In this embodiment, the light intensity data can be collected by a photoelectric sensor arranged on the vehicle, for example, the photoelectric sensor can be a sunlight sensor. In other embodiments, the light intensity data can also be obtained by a pyranometer or a light intensity measuring instrument, and this application does not limit the collection method of the light intensity data.

[0050] Step 103: Obtain the light directness rate based on the vehicle side area, the sun altitude angle and the driving deflection angle.

[0051] In this embodiment, the direct light rate represents the magnitude of the heat load generated by the vehicle being irradiated by sunlight. In order to obtain the direct light rate, the direct light area needs to be calculated first, wherein the direct light area is the sum of the projection areas of multiple sides in the projection direction when the sunlight is directly irradiated on each side of the vehicle, and the projection direction is the direction that is at a driving deflection angle with the projection of the sunlight on the ground plane and is perpendicular to the driving deflection angle.

[0052] Specifically, based on the side area of ​​the vehicle, the sun altitude angle and the driving deflection angle, the direct light area is obtained; the quotient of the side area of ​​the vehicle and the direct light area is taken as the direct light rate. In one embodiment, the direct light area includes the sum of the direct light area on the front side and the direct light area on the rear side. In another embodiment, the direct light area includes the sum of the direct light area on the left side, the direct light area on the right side and the direct light area on the top surface. In yet another embodiment, the direct light area includes the sum of the direct light area on the front side, the direct light area on the rear side, the direct light area on the left side, the direct light area on the right side and the direct light area on the top surface. Among them, the front direct area is the projection area of ​​the front area in the projection direction when the sun is directly shining on the front area. Similarly, the back direct area is the projection area of ​​the back area in the projection direction when the sun is directly shining on the back area. The left direct area is the projection area of ​​the left area in the projection direction when the sun is directly shining on the left area. The right direct area is the projection area of ​​the right area in the projection direction when the sun is directly shining on the right area. The top direct area is the projection area of ​​the top area in the projection direction when the sun is directly shining on the top area.

[0053] In this embodiment, the light direct illumination area includes the sum of the front direct illumination area, the rear direct illumination area, the left direct illumination area, the right direct illumination area and the top direct illumination area as an example for description.

[0054] The following is the specific calculation process of the front direct area, the rear direct area, the left direct area, the right direct area and the top direct area.

[0055] (1) The calculation steps of the front direct area include: Get the first inclination angle, where the first inclination angle is the angle between the area where the front windshield is located and the ground plane. Figure 4 , the first inclination angle is recorded as α. Based on the front area, the first inclination angle, the sun altitude angle and the driving deflection angle, the front direct area is obtained.

[0056] In this embodiment, The product of is taken as the front direct area, where S1 is the front area.

[0057] (2) The calculation steps of the rear direct area include: A second inclination angle is obtained, wherein the second inclination angle is the angle between the area where the rear windshield is located and the ground plane. Based on the rear side area, the second inclination angle, the sun altitude angle and the driving deflection angle, the rear side direct illumination area is obtained.

[0058] In this embodiment, The product of is taken as the rear side direct area, where S2 is the rear side area and β is the second inclination angle.

[0059] (3) The calculation steps for the left direct area include: Based on the left side area, the sun altitude angle and the driving deflection angle, the left side direct illumination area is obtained.

[0060] In this embodiment, The product of is taken as the left direct area, where S3 is the left area.

[0061] (4) The calculation steps for the direct area on the right side include: Based on the right side area, the sun altitude angle and the driving deflection angle, the right side direct illumination area is obtained.

[0062] In this embodiment, The product of is taken as the right direct area, where S4 is the right area.

[0063] (5) The calculation steps of the top surface direct area include: Based on the top surface area and the sun altitude angle, the top surface direct area is obtained.

[0064] In this embodiment, The product of is taken as the direct area on the right side, where S5 is the top surface area.

[0065] In this embodiment, + + + + The sum of S1+S2+S3+S4+S5 is taken as the direct area of ​​light. The quotient of the direct area of ​​light and the sum of S1+S2+S3+S4+S5 is taken as the direct rate of light.

[0066] In this embodiment, when the light directness rate is greater, it means that the area of ​​the vehicle directly exposed to the sun's rays is larger, the area of ​​the vehicle heated by the sun is larger, and the heat load generated by the vehicle being exposed to the sun's rays is larger; conversely, when the light directness rate is smaller, it means that the area of ​​the vehicle directly exposed to the sun's rays is smaller, the area of ​​the vehicle heated by the sun is smaller, and the heat load generated by the vehicle being exposed to the sun's rays is smaller.

[0067] Step 104: Correct the light intensity data using the light directness to obtain corrected light intensity data.

[0068] The light intensity data is corrected using the direct light rate to obtain accurate light intensity data, which is convenient for adjusting the operating data of the vehicle's temperature control system based on the corrected light intensity data, thereby improving the passenger's driving experience. The specific correction process is described in detail in the subsequent steps, and will not be repeated here to avoid repetition.

[0069] Step 105: Adjust the operating data of the temperature control system in the vehicle based on the corrected light intensity data.

[0070] In some embodiments, the temperature control system may be an air conditioner, and the operating data of the temperature control system may include the air volume and the air temperature. In other embodiments, the temperature control system may also be a heating device or a cooling device, and the operating data of the temperature control system may also include the air angle, etc. This application does not limit the type of temperature control system and the specific type of operating data.

[0071] 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.

[0072] For the adjustment of air volume, please refer to Table 1: For adjustment of the outlet air temperature, please refer to Table 2: From Table 1, it can be seen that when the ambient temperature of the vehicle is 10 degrees and the corrected light intensity data is 200, the existing air volume needs to be increased by 3%. From Table 2, it can be seen that when the ambient temperature of the vehicle is 10 degrees and the corrected light intensity data is 1000, the existing air temperature needs to be reduced by 1°.

[0073] It should be noted that the data in Table 1 and Table 2 are for illustration only and do not limit the content of this application. Corresponding adjustment rules can be set according to the actual adjustment requirements of the operating data. At the same time, if the operating data also includes other data besides the air volume and air temperature, corresponding adjustment rules can also be set for other data.

[0074] Compared with the related art, the embodiments of the present application have at least the following advantages: According to the location of the vehicle and the current time, the accurate solar altitude angle and driving deflection angle of the vehicle at different locations can be obtained in real time. Then, using the side area of ​​the vehicle, the solar altitude angle and the driving deflection angle, the light directness can be calculated to accurately reflect the heat load of the vehicle exposed to sunlight when the vehicle is at its current location. When the light directness is large, it indicates that the heat load of the vehicle exposed to sunlight is large; when the light directness is small, it indicates that the heat load of the vehicle exposed to sunlight is small. In this way, the light intensity data is corrected based on the light directness, and the real light intensity of the vehicle when exposed to sunlight can be obtained. Finally, the corrected light intensity data adjusts the operating data of the temperature control system in the vehicle, thereby improving the driving experience of passengers.

[0075] See also Figure 5 , Figure 5 Another flow chart of the vehicle temperature adjustment method provided in the embodiment of the present application. 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 when one side of the vehicle is irradiated by sunlight, and the second light intensity is the light intensity when the other side of the vehicle is irradiated by sunlight.

[0076] In this embodiment, two sunlight sensors (referred to as the first sensor and the second sensor) are arranged on the top of the vehicle, and the first sensor and the second sensor are respectively located on opposite sides of the top position where the central rearview mirror is located. The first sensor is used to collect the light intensity of the left side of the vehicle irradiated by sunlight (referred to as the first light intensity), and the second sensor is used to collect the light intensity of the right side of the vehicle irradiated by sunlight (referred to as the second light intensity).

[0077] In other embodiments, the two sunlight sensors may also be located on opposite sides of the skylight, where one sunlight sensor is used to collect the first light intensity and the other is used to collect the second light intensity. The present application does not limit the specific positions of the two sunlight sensors.

[0078] The specific steps of correcting the light intensity data by using the direct light rate to obtain the corrected light intensity data include: Step 201: Calculate the intensity difference between the first light intensity and the second light intensity.

[0079] In this embodiment, the intensity difference is an absolute value of the difference between the first light intensity and the second light intensity.

[0080] Step 212: When the intensity difference is greater than a preset difference, calculate the intensity average of the first illumination intensity and the second illumination intensity and the illumination difference.

[0081] In this embodiment, the illumination difference is the difference between the first illumination intensity and the second illumination intensity. It is detected whether the intensity difference is greater than the preset difference. If it is detected that 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 light directness to obtain a third illumination intensity. The preset difference can be 200, 300 or 400, and the specific value of the preset difference can be set according to the specific correction requirements.

[0082] When the intensity difference is greater than the preset difference, it indicates that the sunlight is shining on the vehicle from the side. In order to obtain accurate illumination intensity data, the first illumination intensity and the second illumination intensity need to be corrected. The intensity mean is (TL+TR) / 2, and the illumination difference is TL-TR.

[0083] Step 213: Correct the first illumination intensity based on the intensity mean, the illumination difference and the illumination directness to obtain a third illumination intensity.

[0084] Further, it is detected whether the first light intensity is greater than the second light intensity. When it is detected that 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 obtained using formula 1: Formula 1: Among them, TL is the first light intensity, TR is the second light intensity, γ is the light directness, and TL1 is the third light intensity.

[0085] When it is detected that the first light intensity is not greater than the second light intensity, it indicates that the sunlight is shining on the right side of the vehicle, and the third light intensity is obtained using Formula 2: Formula 2: In this way, no matter the sunlight illuminates the vehicle from the left or right side, the accurate third light intensity can be obtained.

[0086] Step 214: Correct the second illumination intensity based on the intensity mean, the illumination difference, and the light directness to obtain a fourth illumination intensity.

[0087] Similarly, when it is detected that the first light intensity is greater than the second light intensity, the fourth light intensity is obtained using Formula 3: Formula 3: Wherein, TR1 is the fourth light intensity.

[0088] When it is detected that the first light intensity is not greater than the second light intensity, the fourth light intensity is obtained using Formula 4: Formula 4: In this way, no matter the sunlight illuminates the vehicle from the left side or the right side, the accurate fourth light intensity can be obtained.

[0089] Step 222: When the strength difference is not greater than the preset difference, detect whether the driving deflection angle is greater than the preset deflection angle.

[0090] When the intensity difference is not greater than the preset difference, it indicates that the sunlight shines 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.

[0091] By detecting whether the driving deflection angle is greater than a preset deflection angle, it is determined whether the sunlight is irradiating the front side of the vehicle or the rear side of the vehicle. The preset deflection angle is 90 degrees.

[0092] Step 223: When it is detected that the driving deflection angle is greater than the preset deflection angle, the first light intensity is corrected based on the first preset coefficient, the first light intensity, the second light intensity and the light directness to obtain a fifth light intensity.

[0093] When it is detected that the driving deflection angle is greater than the preset deflection angle, it indicates that the sunlight is irradiating the rear side of the vehicle. The fifth light intensity is obtained using the following formula 5: Formula 5: Among them, K1 is the first preset coefficient, and the specific value of K1 can be set and changed according to the requirements of correction. This application does not limit the specific value of K1.

[0094] Step 224: correct the second illumination intensity based on the second preset coefficient, the first illumination intensity, the second illumination intensity and the light directness to obtain a sixth illumination intensity.

[0095] In this embodiment, the sixth light intensity is obtained using the following formula 6: Formula 6: Among them, K2 is the second preset coefficient, and the specific value of K2 can be set and changed according to the correction requirements. This application does not limit the specific value of K2.

[0096] It should be noted that the specific values ​​of the first preset coefficient and the second preset coefficient can be adjusted according to the difference between the actual first light intensity and the second light intensity and the revised fifth light intensity and the sixth light intensity during the calibration process.

[0097] Step 233: When it is detected that the driving deflection angle is not greater than the preset deflection angle, the first light intensity is used as the fifth light intensity, and the second light intensity is used as the sixth light intensity.

[0098] When it is detected that the 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, the embodiment of the present application can directly use the first light intensity as the fifth light intensity and the second light intensity as the sixth light intensity.

[0099] Compared with the related art, the embodiments of the present application have at least the following advantages: First, detect whether the intensity difference between the first light intensity and the second light intensity is greater than the preset difference, so as to determine whether the sunlight is irradiated on the side, front or back of the vehicle. If the sunlight is irradiated on the left side of the vehicle, the third light intensity and the fourth light intensity are calculated according to Formula 1 and Formula 3. If the sunlight is irradiated on the right side of the vehicle, the third light intensity and the fourth light intensity are calculated according to Formula 2 and Formula 4. If the sunlight is irradiated on the rear side of the vehicle, the fifth light intensity and the sixth light intensity are calculated according to Formula 5 and Formula 6. If the sunlight is irradiated on the front side 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, the corrected and accurate light intensity data can be obtained, which is convenient for the subsequent use of the corrected light intensity data to adjust the operating data of the temperature control system to improve the driving experience of passengers.
