Description

Technical Field

[0001] This application relates to the field of intelligent adjustment technology for sunshades, and in particular to a method, system, storage medium, and vehicle for adjusting sunshades. Background Technology

[0002] With the upgrading of road traffic and changes in weather, vehicles often need to drive on roads with varying lighting conditions, such as under bridges, in tunnels, and at sunset. However, direct sunlight can cause blind spots for drivers. Therefore, vehicles are usually equipped with sun visors, which have the functions of protecting against ultraviolet rays and reflecting light to reduce glare caused by sunlight. To a certain extent, sun visors can protect the driver's and passengers' vision, improve driving safety, and reduce the temperature inside the vehicle.

[0003] However, manually adjusting the sun visor while moving between bright and dark environments may distract the driver, posing a potential danger to driving safety and, in severe cases, endangering the lives of the driver and passengers. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a method, system, storage medium, and vehicle for automatically adjusting a sunshade based on the angle of light.

[0005] Specifically, this application provides a method for adjusting a light-shielding plate, including the following steps:

[0006] S100: Real-time acquisition of the incident light angle, and acquisition of the initial light angle based on the incident light angle.

[0007] S200: Obtain the initial voltage value corresponding to the initial light angle. After the initial voltage value changes to the adjustment voltage value, calculate the adjustment light angle based on the initial light angle, the initial voltage value, and the adjustment voltage value.

[0008] S300: Adjust the light shield to the complementary angle of the light angle according to the light angle adjustment.

[0009] The described sunshade adjustment method enables the sunshade to automatically adjust to the corresponding position according to changes in the angle of light, effectively reducing driving safety hazards caused by light problems; it requires no manual intervention, so that the driver does not need to frequently adjust the sunshade during driving, reducing interference and operational burden during driving; it can also maintain suitable lighting in the cockpit, thereby providing a better driving and riding experience; at the same time, it can also reduce the interior temperature by reasonably adjusting the position of the sunshade, reduce the use of air conditioning, and improve energy efficiency.

[0010] Step S100 includes: when the incident light angle is equal to a preset light angle threshold, the incident light angle is determined as the initial light angle.

[0011] Obtain the initial light angle for subsequent calculations and adjustments.

[0012] Step S200 includes: converting the initial voltage value and the adjusted voltage value into an initial voltage digital signal and an adjusted voltage digital signal, respectively; and calculating the adjusted light angle based on the initial light angle, the initial voltage digital signal, and the adjusted voltage digital signal.

[0013] The initial voltage value and the adjusted voltage value are both converted into corresponding digital signals because digital signals can be represented in a discretized way. Compared with continuous analog signals, digital signals are easier to process, store and transmit. Furthermore, converting continuous voltage values ​​into discrete values ​​makes the numerical processing process more reliable and stable.

[0014] Then it was calculated that adjusting the angle of the light was for the subsequent adjustment of the light shield.

[0015] Step S300 includes:

[0016] A drive signal is output according to the adjusted light angle to adjust the light shield to the complementary angle of the adjusted light angle.

[0017] It should be noted that the angle of light adjustment + the angle of light shield adjustment = 90°.

[0018] Converting the adjustment of the light angle into a drive signal is to control and drive the actuator's light shield to achieve the required angle adjustment.

[0019] Among them, the driving signal is a digital signal. Using digital signals to control the light shield can achieve accurate and reliable angle adjustment.

[0020] Based on the same concept, this application also provides a light-shielding plate adjustment system, the system comprising:

[0021] First acquisition module: used to acquire the incident light angle and acquire the initial light angle based on the incident light angle.

[0022] The second acquisition module is used to acquire the corresponding initial voltage value based on the initial light angle.

[0023] Calculation module: used to calculate the adjustment light angle based on the initial light angle, the initial voltage value, and the adjustment voltage value after the initial voltage value changes to the adjustment voltage value.

[0024] Drive module: used to adjust the light shield to a complementary angle to the light angle according to the light angle adjustment.

[0025] The computing module includes:

[0026] Analog-to-digital conversion unit: used to convert the initial voltage value and the adjusted voltage value into an initial voltage digital signal and an adjusted voltage digital signal, respectively, after the initial voltage value changes to the adjusted voltage value.

[0028] The system also includes:

[0029] Power supply module: used to supply power to the first acquisition module, the second acquisition module, the analog-to-digital conversion unit, the calculation unit, the signal output unit, and the drive unit.

[0030] The sun visor adjustment system enables the sun visor to automatically adjust to the appropriate position according to changes in the angle of light, effectively reducing driving safety hazards caused by light problems; reducing interference and operational burden during driving; and maintaining suitable lighting in the cockpit, thereby providing a better driving and riding experience; at the same time, it can also reduce the interior temperature by reasonably adjusting the position of the sun visor, reducing the use of air conditioning and improving energy efficiency.

[0031] The driving module includes:

[0032] Signal output unit: used to output a drive signal based on the calculation result of the calculation unit.

[0033] Drive unit: used to adjust the light shield to a complementary angle to the angle of the adjusted light according to the output result of the signal output unit.

[0034] The signal output unit is responsible for converting the angle of the adjusted light into a driving signal suitable for the operation of the drive unit. The drive unit then performs the specific rotation task and controls and adjusts the light shield according to the driving signal to achieve the required adjustment angle.

[0035] The signal output unit and the drive unit work together to achieve precise motion control and drive of the light-shielding plate.

[0036] Based on the same concept, this application also provides a storage medium, which is a type of computer-readable storage medium, wherein the computer-readable storage medium stores computer instructions for causing a computer to perform the aforementioned light-shielding plate adjustment method.

[0037] Based on the same concept, this application also provides a vehicle that includes at least the system of the aforementioned sunshade adjustment method.

[0038] Compared with the prior art, the beneficial effects of this application are as follows:

[0039] This application calculates the adjusted light angle based on the initial light angle, initial voltage value, and adjusted voltage value, thereby adjusting the sun visor to a complementary angle to the adjusted light angle. This application effectively reduces driving safety hazards caused by lighting issues; reduces interference and operational burden during driving; and maintains suitable lighting in the cockpit, providing a better driving and riding experience. Simultaneously, it can lower the interior temperature by reasonably adjusting the position of the sun visor, reducing air conditioning usage and improving energy efficiency.

[0042] This application provides a sun visor adjustment method, system, storage medium, and vehicle to solve the technical problem in the prior art where manually adjusting the sun visor distracts the driver and thus poses a potential danger to driving safety.

[0043] The following detailed description, in conjunction with specific embodiments and accompanying drawings, describes a method, system, storage medium, and vehicle for adjusting a sunshade according to this application.

[0044] Example 1:

[0045] Please see Figure 1 This application provides a method for adjusting a light-shielding plate, comprising the following steps:

[0046] S100: Real-time acquisition of the incident light angle, and acquisition of the initial light angle based on the incident light angle.

[0047] Step S100 includes: when the incident light angle is equal to a preset light angle threshold, the incident light angle is determined as the initial light angle.

[0048] In this embodiment, incident light is received by a photosensitive receiver. When the angle of the incident light received by the photosensitive receiver is equal to a preset light angle threshold, the incident light angle at this time can be regarded as the initial light angle.

[0049] The preset angle threshold is equal to 90°, at which point the incident light is perpendicular to the light shield; assuming the initial light angle is θ, the angle of the light shield is φ; θ + φ = 90°.

[0050] S200: Obtain the initial voltage value corresponding to the initial light angle. After the initial voltage value changes to the adjustment voltage value, calculate the adjustment light angle θ1 based on the initial light angle θ, the initial voltage value, and the adjustment voltage value.

[0051] It should be noted that any change in the initial voltage value can be considered as the adjusted voltage value.

[0052] Step S200 includes: converting the initial voltage value and the adjusted voltage value into an initial voltage digital signal Vx and an adjusted voltage digital signal Vx1, respectively; and calculating the adjusted light angle based on the initial light angle, the initial voltage digital signal Vx, and the adjusted voltage digital signal Vx1.

[0053] The photosensitive receiver can generate voltage changes based on the intensity of the received light. A microcontroller converts the initial voltage value and the adjusted voltage value into an initial voltage digital signal Vx and an adjusted voltage digital signal Vx1, respectively; then, according to... It is possible to obtain and adjust the angle θ1 of the light.

[0054] Converting voltage values ​​into corresponding digital signals offers numerous advantages. First, digital signals are easier to process, store, and transmit. By converting continuous voltage values ​​into digital signals, more reliable and stable numerical processing can be achieved. Furthermore, digital signals can be sampled and quantized, thereby improving the reliability and accuracy of signal processing. Second, digital signals have stronger noise immunity, which enhances signal instruction and reliability. In addition, the high resolution and precision of digital signals allow for more accurate representation of voltage values, resulting in more precise calculation results.

[0055] S300: Adjust the light shield to the complementary angle φ1 of the light angle θ1 according to the light angle θ1.

[0056] Step S300 includes:

[0057] A drive signal is output according to the adjusted light angle to adjust the light shield to the complementary angle φ1 of the adjusted light angle θ1.

[0058] The microcontroller then outputs a drive signal based on the calculated adjustment light angle θ1, and sends the drive signal to the motor drive module, so that the motor drive module drives the motor to rotate the light shield to the complementary angle φ1 of the adjustment light angle θ1.

[0063] The preset angle threshold is equal to 90°. At this time, the incident light is perpendicular to the light shield, and the photosensitive receiver can receive the change in light.

[0064] The second acquisition module is used to acquire the corresponding initial voltage value based on the initial light angle.

[0065] The second acquisition module is also a photosensitive receiver, which can generate voltage changes based on the intensity of the received light.

[0066] When light shines on a photosensitive receiver, the photosensitive material will experience a change in resistance or current, which can be obtained by measuring the voltage or current.

[0067] It should be noted that the voltage value output by the photosensitive receiver varies depending on the intensity of the light.
