[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] An embodiment of the present application provides a control method for a louvered sunroof control system in a vehicle to solve the problems that due to the complex driving conditions of the vehicle and the particularity of the vehicle sunroof structure, as an essential key component, the slide rail has a high cost, is easily damaged, and there will be abnormal noises and deformations after the slide rail is assembled with the vehicle, resulting in frequent replacement of the slide rail.

[0048] Please refer to Figure 1 , the louvered sunroof control system in the vehicle at least includes: a drive motor 1, a drive rack 3, a controller (not shown in the figure), and a plurality of fan blades 2; the controller is connected to the drive motor 1, and the drive motor 1 and each fan blade 2 are respectively engaged with the drive rack 3 through corresponding gears.

[0049] The drive motor 1 is controlled by the controller. The drive motor 1 drives the gear to rotate to cause the drive rack 3 to generate a displacement. The displacement of the drive rack 3 further drives the gear corresponding to the fan blade 2 to rotate, thereby controlling the rotation angle of the fan blade 2.

[0050] In practice, in order to ensure tooth profile matching and smooth meshing, the module ratio of the gear and the drive rack 3 is 1; since the main function of the gear and the drive rack 3 in the present application is to drive the louvered fan blades to rotate, and the application environment of the louvered fan blades in the present application is a vehicle. Considering the application environment and manufacturing cost, materials such as aluminum alloy, polyvinyl chloride, cloth, fiberglass, and carbon fiber can be selected to make the fan blades 2. Further, since the fan blades 2 are all made of materials with relatively low density, the load-bearing capacity required for the teeth of the gear and the drive rack 3 is relatively low, and the module of the gear and the drive rack 3 can be set to a smaller value.

[0051] In one embodiment, in order to reduce the manufacturing cost, gears can be provided only on one side of the fan blade 2, as Figure 1 shown.

[0052] Similarly, in combination with Figure 1, in order to ensure good fixing effect of each louver blade 2 in the louvered sunshade control system, it can be fixed through the blade fixing bracket 4. The fixing blade bracket 4 can be set according to the size of the louver blade, and no specific limitation is made in this application, all within the protection scope of this application.

[0053] In practical applications, in order to achieve high-precision control, the drive motor 1 can be a stepper motor; of course, it is not limited to this, and it can also be other existing motors, such as servo motors, ultrasonic motors, etc., which can be determined according to the application environment and user requirements, all within the protection scope of this application.

[0054] Exemplarily, taking the stepper motor as an example, in order to ensure high transmission efficiency, precision and stability in the cooperation between the motor and the gear, a key connection can be adopted between the stepper motor and the corresponding gear.

[0055] It should be noted that the louvered sunshade control system in the vehicle provided in this application adopts a gear and rack meshing connection structure, which has higher stability, is convenient for maintenance and replacement, and has lower cost, solving the problems of the existing skylight mechanism using a slide rail, such as high cost, easy damage, and abnormal noise and deformation generated after the slide rail is assembled with the vehicle, resulting in frequent replacement of the slide rail.

[0056] It should also be noted that with the increasing requirements for the stability of vehicle electronic components, the opening of the existing skylight curtain often requires a long response time and a slow execution time, and once the sunshade is opened, only the displacement size of the curtain can be controlled to control the light entering effect of some positions inside the vehicle, lacking the control of the overall light intake inside the vehicle, which affects the riding experience of the driver and passengers. While the louvered sunshade control system of this application can adjust the rotation angle of the louver blades through the transmission rack 3 to achieve different degrees of light entering effects, improving the riding experience of the driver and passengers.

[0057] Based on the above louvered sunshade control system in the vehicle, another embodiment of this application also provides a control method for the louvered sunshade control system in the vehicle, which is applied to the controller in the louvered sunshade control system. Please refer to Figure 2 , and this method mainly includes the following steps:

[0058] S101. Determine the solar altitude angle of the vehicle.

[0059] Among them, the solar altitude angle of the vehicle is the solar altitude angle at the current position of the vehicle.

[0060] In one example, the specific process of step S101, determining the solar altitude angle of the vehicle, is as Figure 3 shown, and mainly includes steps S201 and S202:

[0061] S201. Obtain the time information and geographical location information of the vehicle.

[0062] Among them, the time information includes at least the current date and current time of the vehicle, and the geographical location information includes at least the current latitude of the vehicle.

[0063] In practical applications, the specific process of step S201, obtaining the time information and geographical location information of the vehicle is as Figure 4 shown, mainly including steps S301 and S302:

[0064] S301. Obtain the message bus information of the vehicle.

[0065] Among them, the message bus information of the vehicle is the information transmitted on the message bus in the vehicle, including the information sent by all the controllers connected to the message bus on the vehicle.

[0066] Since the controller in the louvered sunroof control system is connected to the message bus of the vehicle, the information sent by other controllers in the vehicle to the message bus can be obtained through the message bus.

[0067] Among them, other controllers in the vehicle can be controllers in the powertrain control system, chassis and safety system, body electronics system, infotainment and network system, new energy vehicle control system or advanced driver assistance system, which can be determined according to the application environment and user requirements.

[0068] S302. Obtain the time information and geographical location information of the vehicle according to the message bus information.

[0069] Since the message bus information of the vehicle includes the message information of other controllers in the vehicle, and the message information sent by different controllers in the vehicle carries the time information and geographical location information of the vehicle, the time information and geographical location information of the vehicle can be obtained by parsing the message bus data.

[0070] In practice, the time information and geographical location information of the vehicle can be obtained through other information sensors and vehicle networking devices of the vehicle, such as the current date T1, the current time T2 (unit: hour) and the latitude L1; and the heading angle K of the vehicle can be obtained through the networked navigation control.

[0071] It should be noted that according to the existing technical level, the time information and geographical location information of the vehicle are relatively easy to obtain and the data values are relatively accurate, and there is no need to use an additional controller to obtain them, which can save control costs to a certain extent.

[0072] S202. Obtain the solar altitude angle of the vehicle according to the time information and geographical location information.

[0073] In one example, the specific implementation process of step S202, obtaining the solar altitude angle of the vehicle according to the time information and the geographical location information, is as follows Figure 5 and mainly includes steps S401 and S402:

[0074] S401. Obtain the declination angle and the solar hour angle of the vehicle according to the current date and the current time of the vehicle.

[0075] In practical applications, the declination angle of the vehicle can be calculated according to the current date of the vehicle.

[0076] Specifically, the declination angle δ of the vehicle can be calculated by formula 1:

[0077] δ = 23.44° × sin(360 / 365 × (T1 + 10)) (formula 1); where T1 represents the current date of the vehicle.

[0078] In practical applications, the solar hour angle of the vehicle can be calculated according to the current time of the vehicle.

[0079] Specifically, the solar hour angle H of the vehicle can be calculated by formula 2:

[0080] H = 15° × (T2 - 12) (formula 2); where T2 represents the current time of the vehicle.

[0081] S402. Obtain the solar altitude angle of the vehicle according to the current latitude, the declination angle and the solar hour angle of the vehicle.

[0082] In practical applications, the solar altitude angle h of the vehicle can be calculated by the following formula:

[0083] h = arcsin(sin(L1) ⋅ sin(δ) + cos(L1) ⋅ cos(δ) ⋅ cos(H)); where L1 represents the current latitude of the vehicle.

[0084] S102. Obtain the target rotation angle of the fan blade according to the heading angle of the vehicle, the target solar light input amount and the solar altitude angle.

[0085] Among them, the target solar light input amount is the solar light input amount required by the vehicle.

[0086] In practical applications, the driver or the passenger can realize the irradiation area range of the light inside the vehicle according to their own needs, preset the light input amount inside the vehicle (0 - 100%) through the central control multimedia module of the vehicle, and send this signal to the message bus. The controller in the louvered sunroof control system can obtain it from the message bus, so as to obtain the target solar light input amount.

[0087] In one embodiment, in step S102, according to the heading angle of the vehicle, the target solar light intake, and the solar altitude angle, the target rotation angle of the fan blades is obtained. The specific implementation process of the target solar light intake, which is the solar light intake required by the vehicle, is as follows Figure 6 shown, and mainly includes steps S501 and S502:

[0088] S501. Determine the range interval to which the heading angle belongs. Different range intervals correspond to different rotation angle calculation formulas.

[0089] In practical applications, the heading angle can be divided into four range intervals, namely: 0°≤K<90°, 90°≤K<80°, 180°≤K<70°, 270°≤K≤360°. The rotation angle calculation formulas corresponding to each interval are as follows:

[0090] ;

[0091] , , where K represents the heading angle, h represents the solar altitude angle, P represents the target solar light intake, and W represents the rotation angle.

[0092] It should be noted that the angle of the fan blades in the tiled state is 0°, and the solar light intake is 0.

[0093] S502. According to the heading angle, the target solar light intake, and the solar altitude angle, use the rotation angle calculation formula corresponding to the range interval to which the heading angle belongs to calculate, and obtain the target rotation angle of the fan blades.

[0094] In practice, the target rotation angle of the fan blades is the angle at which the fan blades rotate when the light intake of the vehicle is the target solar light intake.

[0095] After knowing the rotation angle calculation formula corresponding to the range interval to which the heading angle belongs, the heading angle, the target solar light intake, and the solar altitude angle can be substituted into the corresponding rotation angle calculation formula to obtain the target rotation angle of the fan blades.

[0096] It should be noted that since the heading angle corresponds to different rotation angle calculation formulas in different range intervals, the rotation angle calculation formula corresponding to the range interval to which the heading angle belongs can be dynamically selected according to the heading angle, the target solar light intake, and the solar altitude angle for calculation, so as to obtain the target rotation angle of the fan blades, thereby improving the control accuracy of the solar light intake and further improving the riding comfort.

[0097] S103. Control the drive motor to rotate the fan blades to the target rotation angle.

[0098] In practice, after learning the target rotation angle of the fan blade, the driving motor can be controlled to rotate, thereby driving the driving rack to displace, so that the fan blade rotates to the target rotation angle, thereby meeting the requirement of the target solar light input amount.

[0099] It should be noted that the above control method of the louvered sunroof control system in the vehicle can be executed when the controller in the louvered sunroof control system is in the on state; after adjusting the fan blade to the target rotation angle, the controller in the louvered sunroof control system can be controlled to be in the sleep state and woken up when the light input amount needs to be adjusted next time.

[0100] Based on the above, the control method of the louvered sunroof control system in the vehicle provided in this embodiment is applied to the controller in the louvered sunroof control system. The louvered sunroof control system at least includes: a driving motor, a driving rack, a controller, and a plurality of fan blades; the controller is connected to the driving motor, and the driving motor and each fan blade are respectively meshed with the driving rack through corresponding gears. The method includes: determining the solar altitude angle of the vehicle; obtaining the target rotation angle of the fan blade according to the heading angle of the vehicle, the target solar light input amount, and the solar altitude angle, where the target solar light input amount is the solar light input amount required by the vehicle; controlling the driving motor so that the fan blade rotates to the target rotation angle. The louvered sunroof control system adopts a gear and rack meshing connection structure, which has higher stability, is convenient for maintenance and replacement, has a lower cost, and can control the solar light input amount according to different requirements in combination with the position of the vehicle, solving the problems of the existing sunroof mechanism using a slide rail, such as high cost, easy damage, and abnormal noise and deformation generated after the slide rail is assembled with the vehicle, resulting in frequent replacement of the slide rail.

[0101] It is worth noting that the control method provided in this application can control the light input amount in the vehicle according to different requirements of passengers or drivers in combination with the position of the vehicle, so as to achieve different light input effects, with simple control, convenient for passengers to operate, short response and execution time of the mechanism, and greatly improving the driving safety and riding comfort of passengers.
