[0038] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. 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.

[0040] The embodiments in the application and the features in the embodiments can be combined with each other without conflict.

[0041] Embodiment one

[0042] The embodiment one of the application introduces an intelligent control method of automobile sunroof based on solar energy.

[0043] An intelligent control method of automobile sunroof based on solar energy, comprising:

[0044] Obtaining the illumination intensity and the illumination angle, and judging whether the automobile sunroof solar energy reaches the maximum power point tracking;

[0045] When the maximum power point tracking is reached, obtaining the real-time temperature in the car;

[0046] When the obtained real-time temperature in the car is greater than the preset temperature, applying voltage to the automobile sunroof, adjusting the color of the dimming glass layer of the automobile sunroof, increasing the light reflection area of the dimming glass layer of the automobile sunroof, and reducing the temperature in the car;

[0047] When the obtained temperature in the car is not greater than the preset temperature, adjusting the sunshade curtain of the automobile sunroof to reduce the light area of the automobile sunroof.

[0048] The embodiment is based on the technology of converting solar energy into electric energy by the whole vehicle. The sunlight can be offset by a part of heat by the photovoltaic semiconductor assembly, and the temperature of the sky screen is reduced. At the same time, the voltage obtained based on the solar energy is inverted into 12V voltage by the maximum power point tracking (MPPT) control module. The intelligent ventilation request is sent to the MPPT by the CEM (vehicle body controller) in the whole vehicle control system, so that the automobile has the memory intelligent ventilation function. When the whole vehicle is in the power-off state, the temperature in the vehicle is obtained by the temperature sensor. When the obtained temperature in the vehicle is greater than the preset temperature, the air conditioner is driven by the enable signal of the TMM under the action of the MPPT control module, so as to realize the cooling of the vehicle. When the MPPT control module detects that the vehicle is unblocked (the automobile door is opened or the trunk is opened or the sunroof is opened or the window is opened) or the temperature in the vehicle is not greater than the preset temperature, the intelligent ventilation function is exited, and the TBOX (smart networking) sends information to the cloud. Since the MPPT and the TBOX communicate through the CAN bus, when the MPPT does not detect the IGN power, the information is sent to the TBOX. The TBOX receives the signal request and feeds back the request message to the network. At this time, other devices in the vehicle do not receive the corresponding message information to ensure the sleep state. The user APP sends the signal to the cloud platform through 5G. The cloud platform sends the information to the TBOX. The TBOX sends the information to the MPPT control module through the CAN bus. Based on the MPPT control module, the sunshade curtain of the automobile sky screen is adjusted. The sunshade curtain motor is driven, so that the sunshade curtain can offset another part of light of the automobile sky screen, and the light area of the automobile sky screen is reduced.

[0049] When the temperature sensor detects that the temperature in the vehicle is greater than the preset temperature, the voltage is applied to the automobile sky screen based on the MPPT control module, the color of the dimming glass layer of the automobile sky screen is adjusted, the light reflection area of the dimming glass layer of the automobile sky screen is increased, and the temperature in the vehicle is reduced. According to the obtained detection temperature in the vehicle and the preset temperature, the voltage is applied to the automobile sky screen. The size of the applied voltage is determined according to the size of the outdoor temperature detected by the TEMS (outdoor temperature sensor). The glass atoms in the automobile sky screen react based on the electric field effect. The automobile sky screen displays different colors when different voltages are applied, so as to realize the adjustment of the color of the dimming glass layer of the automobile sky screen.

[0050] It should be noted that in the process of judging whether the solar energy of the automobile sky screen reaches the maximum power point tracking, the solar cell panel is charged according to the light intensity and the light angle, the utilization rate of solar energy is adjusted by the linear curve algorithm, the color of the automobile sky screen and the position of the sunshade curtain of the automobile sky screen are adjusted, so as to obtain the maximum power point tracking. The adjustment of the MPPT is shown in Table 1.

[0051] Table 1 Corresponding relationship between time and MPPT

[0052]

[0053] AsFigure 4 As shown in Table 2, the MPPT detects the indoor temperature, compares the detected temperature with a preset threshold, applies a certain voltage to the sunroof, causes the sunroof glass atoms to react by using the electric field effect, and the sunroof displays different colors according to the applied voltage, resists the ultraviolet rays outside the vehicle, and reduces the temperature in the passenger compartment of the cab.

[0055]

[0056] It should be noted that the preset temperature is determined according to the vehicle model and the geographical environment in which the vehicle is located.

[0057] In the embodiment, the automobile sunroof sunshade curtain is arranged in the vehicle and matches the position of the automobile sunroof; the automobile sunroof sunshade curtain comprises a sunshade curtain roller and a sunshade curtain that can be rolled on the sunshade curtain roller; a sunshade curtain motor is arranged in the sunshade curtain roller, and the sunshade curtain is rolled by controlling the forward and reverse rotation of the sunshade curtain motor; based on the rolling of the sunshade curtain controlled by the motor, this belongs to the prior art known to those skilled in the art, and will not be described in detail in the embodiment.

[0058] As shown in Figure 1 When the vehicle is in the powered state, the user sends a request for the memory intelligent ventilation function to the MPPT control module through the large-screen intelligent ventilation virtual button; when the vehicle is in the OFF state, the air conditioner is automatically switched to the external circulation mode; when the MPPT control module detects that the indoor temperature is greater than the preset temperature through the temperature sensor, the air conditioner speed module is driven under the action of the MPPT control module, and the blower operates at the second speed, thereby cooling the vehicle interior; the MPPT control module wakes up the TBOX through the CGW (gateway) network, the TBOX sends information to the background, and other devices of the vehicle are not awakened; the background sends information to the user APP through the base station, and the user APP displays the working state, working time, voltage, current and other information in real time;

[0059] When the MPPT control module detects that the vehicle is unblocked (the automobile door is opened or the trunk is opened or the sunroof is opened or the window is opened) or the indoor temperature is not greater than the preset temperature, the intelligent ventilation function is exited, and the blower stops operating; under the action of the MPPT control module, the sunshade curtain motor is driven through the SRF (sunshade curtain controller), so that the sunshade curtain can offset part of the light of the sunroof and reduce the light area of the automobile sunroof.

[0060] When the temperature sensor acquires the indoor temperature greater than the preset temperature, the sunroof intelligent control module receives a signal, applies a voltage to the sunroof, the dimming glass layer changes color, reduces the light receiving area, increases the light reflecting area, and reduces the indoor temperature.

[0061] In the embodiment, the structure of the automobile sunroof is as shown in Figure 2As shown, including glass, photovoltaic semiconductor components, light curtain and light control glass layer.

[0062] The pin diagram of the MPPT control module used in the embodiment is as shown in the figure. Figure 3

[0063] The embodiment adjusts the state of the curtain in real time by monitoring the temperature in the vehicle, drives the sunshade curtain motor to cover the curtain, adjusts the light color of the glass layer of the curtain, reduces the light reflection efficiency by using solar technology, maximizes the use scene of the curtain, reduces the temperature in the vehicle, and improves the user experience.
