[0020] The above and / or additional aspects and advantages of the present invention will become apparent and be readily understood from the description of the embodiments in conjunction with the following drawings, where:

[0021] Figure 1 is a flowchart of a control method for a vehicle wireless charging panel according to an embodiment of the present invention;

[0022] Figure 2 is a schematic structural diagram of a control device for a vehicle wireless charging panel according to an embodiment of the present invention. Detailed Embodiments

[0023] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0024] The following references Figure 1 - Figure 2Describe a control method, device, vehicle, and storage medium for a vehicle wireless charging panel according to an embodiment of the present invention.

[0025] Figure 1 It is a flowchart of a control method for a vehicle wireless charging panel according to an embodiment of the present invention. As Figure 1 shown, a control method for a vehicle wireless charging panel includes the following steps:

[0026] Step S1: When the wireless connection between the wireless charging terminal and the vehicle wireless charging panel is successful, obtain the first identification information and temperature information of the wireless charging terminal.

[0027] Specifically, the wireless charging terminal includes, but is not limited to, mobile terminals such as mobile phones, tablets, and laptop computers. When the wireless charging terminal is placed on the vehicle wireless charging panel, the coil built into the vehicle wireless charging panel will sense the change in capacitance and establish a communication connection with the wireless charging terminal by demodulating the ASK (Amplitude Shift Keying) data packet sent by the wireless charging terminal. After the wireless connection between the wireless charging terminal and the vehicle wireless charging panel is successful, the vehicle wireless charging panel obtains the first identification information and temperature information of the wireless charging terminal. Specifically, the first identification information of the wireless charging terminal includes, but is not limited to, the VID (Vendor ID) code, product serial number, and the maximum input power required by the wireless charging terminal of the wireless charging terminal. The vehicle wireless charging panel provides wireless charging services and cooling services to the wireless charging terminal according to the obtained first identification information and temperature information of the wireless charging terminal.

[0028] Step S2: If the first identification information is the identification information in the preset identification library, determine that the control strategy for the charging temperature of the wireless charging terminal is the first control strategy, where the first control strategy includes the corresponding relationship between different temperature information and the rotation speed of the fan.

[0029] Specifically, the preset identification library includes, but is not limited to, device parameters of calibrated wireless charging terminals, such as the model of the wireless charging terminal. When the wireless connection between the wireless charging terminal and the vehicle wireless charging panel is successful, the vehicle wireless charging panel obtains the first identification information of the wireless charging terminal and compares the first identification information with the device parameters stored in the preset identification library. If the first identification information is the identification information in the preset identification library, the first control strategy for the charging temperature of the wireless charging terminal is determined. Specifically, since different models of wireless charging terminals have different characteristics and requirements during wireless charging, in the embodiments of the present invention, the model of the wireless charging terminal is identified, and the temperature during charging of the wireless charging terminal is controlled according to the temperature information of different models of wireless charging terminals during charging, so that the rotation speed of the fan is adapted to the temperature of the wireless charging terminal under the control of the first control strategy, avoiding serious overheating of the wireless charging terminal during the charging process, thereby achieving a better cooling effect and higher charging efficiency. It can be understood that the preset identification library is calibrated in advance and stored in the controller of the vehicle wireless charging panel.

[0030] Step S3: Determine the rotation speed of the fan according to the temperature information and the first control strategy.

[0031] Specifically, the rotation speed of the fan is determined according to the temperature information and the first control strategy, so that the rotation speed of the fan is adapted to the charging temperature of the wireless charging terminal, so as to reduce the charging temperature of the wireless charging terminal to a suitable temperature under the first control strategy through the blowing of the fan. It can be understood that when the wireless charging terminal is charging, too high a charging temperature will reduce the charging efficiency of the wireless charging terminal. In the embodiments of the present invention, the rotation speed of the fan is controlled according to the targeted control strategy, and then the charging temperature of the wireless charging terminal is controlled, improving the heat dissipation effect of the fan and the charging efficiency of the wireless charging terminal.

[0032] In an embodiment of the present invention, after obtaining the first identification information of the wireless charging terminal, it further includes: if the first identification information is not the identification information in the preset identification library, determining that the control strategy for the charging temperature of the wireless charging terminal is the second control strategy; determining the rotation speed of the fan according to the second control strategy to control the charging temperature of the wireless charging terminal.

[0033] Specifically, if the first identification information is not the identification information in the preset identification library, it is considered that there is no preset control strategy for the charging temperature of the wireless charging terminal corresponding to the first identification information, and the control strategy for the charging temperature of the wireless charging terminal is determined as the second control strategy, that is, the default control strategy, to be applicable to the wireless charging terminal without a corresponding control strategy for the charging temperature of the wireless charging terminal. It can be understood that when the second control strategy controls the charging temperature of the wireless charging terminal, it cannot adjust the rotation speed of the fan in real time according to the real-time charging temperature of the wireless charging terminal, and the control process is relatively rough.

[0034] In one embodiment of the present invention, determining the rotation speed of the fan according to the temperature information and the first control strategy includes: determining the temperature range where the temperature information is located; according to the temperature range, querying the preset temperature range - fan rotation speed gear correspondence mapping table in the first control strategy to obtain the fan rotation speed gear corresponding to the temperature range, wherein the temperature range - fan rotation speed gear correspondence mapping table includes at least one set of correspondences between the temperature range and the fan rotation speed gear, and at least one set of correspondences between the temperature range and the fan rotation speed gear includes at least the correspondence between the temperature range and the fan rotation speed gear; controlling the rotation speed of the fan according to the fan rotation speed gear.

[0035] Specifically, in the embodiment of the present invention, by conducting a single-variable experiment on temperature, the heat dissipated by the wireless charging terminal per unit time during charging is measured. The time interval from the start of charging to the wireless charging terminal reaching the highest temperature is divided into multiple temperature ranges. The larger the temperature range, the higher the gear of the fan. Accordingly, the fan rotation speed gears corresponding to different temperature ranges are set to balance the heat generated by the wireless charging terminal during charging and the heat dissipated by the fan.

[0036] In a specific embodiment, after determining the temperature range where the temperature information is located, querying the temperature range - fan rotation speed gear correspondence mapping table preset in the first control strategy can obtain the fan rotation speed gear corresponding to the temperature range. The vehicle wireless charging panel controls the rotation speed of the fan according to the fan rotation speed gear corresponding to the temperature range to reduce the overheated temperature of the wireless charging terminal during charging, improve the heat dissipation effect of the fan and the charging efficiency of the wireless charging terminal, and at the same time reduce power consumption and noise.

[0037] In one embodiment of the present invention, obtaining the temperature information of the wireless charging terminal includes: determining that the wireless charging terminal is in a connected state with the vehicle-mounted communication device, wherein the vehicle-mounted communication device includes vehicle-mounted Bluetooth or vehicle-mounted Wifi; obtaining the temperature information of the wireless charging terminal through the vehicle-mounted communication device.

[0038] Specifically, the in-vehicle communication device includes, but is not limited to, in-vehicle Bluetooth or in-vehicle Wi-Fi. For the convenience of understanding, the in-vehicle Bluetooth is taken as an example in the embodiments of the present invention. When it is determined that the wireless charging terminal is in a connected state with the in-vehicle Bluetooth, the temperature information of the wireless charging terminal is obtained through the in-vehicle Bluetooth, so as to determine the control strategy for the charging temperature of the wireless charging terminal based on the temperature information, so that the rotation speed of the fan can be adapted to the charging temperature of the wireless charging terminal, improving the charging efficiency of the wireless charging terminal and saving electric energy. In some other embodiments, when it is determined that the wireless charging terminal is not in a connected state with the in-vehicle Bluetooth, at this time, the charging temperature of the wireless charging terminal cannot be transmitted through the in-vehicle Bluetooth, and the control strategy for the charging temperature of the wireless charging terminal cannot be determined based on the temperature information of the wireless charging terminal. At this time, the control strategy for the charging temperature of the wireless charging terminal is determined as the second control strategy, so that when the wireless charging terminal is not in a connected state with the in-vehicle Bluetooth, the charging temperature of the wireless charging terminal can still be reduced through the second control strategy.

[0039] In an embodiment of the present invention, before obtaining the temperature information of the wireless charging terminal through the in-vehicle communication device, it further includes: obtaining the second identification information of the wireless charging terminal through the in-vehicle communication device; determining that the first identification information and the second identification information are the same.

[0040] Specifically, the second identification information is obtained by the in-vehicle communication device and transmitted to the vehicle wireless charging panel when the wireless charging terminal is in a connected state with the in-vehicle communication device, including but not limited to the VID code and product serial number of the wireless charging terminal. When the wireless connection between the wireless charging terminal (for example, the first wireless charging terminal) and the vehicle wireless charging panel is successful, if the second identification information obtained through the in-vehicle communication device is not the identification information of the wireless charging terminal connected to the vehicle wireless charging panel, that is, the wireless charging terminal connected to the in-vehicle communication device is another wireless charging terminal (for example, the second wireless charging terminal), then the vehicle wireless charging panel cannot obtain the charging temperature of the current wireless charging terminal (that is, the first wireless charging terminal) through the in-vehicle communication device, and thus cannot determine the control strategy for the charging temperature of the wireless charging terminal based on the temperature information of the wireless charging terminal. Therefore, before obtaining the temperature information of the wireless charging terminal through the in-vehicle communication device, it is necessary to obtain the second identification information of the wireless charging terminal through the in-vehicle communication device and determine that the first identification information and the second identification information are the same, so as to further improve the accuracy of the temperature control of the wireless charging terminal and the charging efficiency of the wireless charging terminal.

[0041] In a specific embodiment, the second identification information of a wireless charging terminal (for example, denoted as the second wireless charging terminal) obtained through a vehicle-mounted communication device such as vehicle-mounted Bluetooth is compared with the first identification information of the wireless charging terminal (for example, denoted as the first wireless charging terminal) obtained by the vehicle wireless charging panel to determine whether the first wireless charging terminal and the second wireless charging terminal are the same wireless charging terminal. Specifically, when the first identification information is the same as the second identification information, it is considered that the first wireless charging terminal and the second wireless charging terminal are the same wireless charging terminal, that is, the wireless charging terminal placed on the vehicle wireless charging panel and the wireless charging terminal connected to the vehicle-mounted Bluetooth are the same wireless charging terminal. Therefore, the step of obtaining the temperature information of the wireless charging terminal through the vehicle-mounted communication device and determining the charging temperature of the wireless charging terminal based on the temperature information can be executed to specifically control the rotation speed of the fan, thereby precisely controlling the charging temperature of the wireless charging terminal and improving the heat dissipation effect of the fan and the charging efficiency of the wireless charging terminal. In other embodiments, when the first identification information and the second identification information are different, it is considered that the first wireless charging terminal and the second wireless charging terminal are not the same wireless charging terminal, that is, the wireless charging terminal placed on the vehicle wireless charging panel and the wireless charging terminal connected to the vehicle-mounted Bluetooth are not the same wireless charging terminal. At this time, the wireless charging terminal cannot transmit the temperature information of the wireless charging terminal through the vehicle-mounted Bluetooth, and the control strategy for determining the charging temperature of the wireless charging terminal is the second control strategy to reduce the charging temperature of the wireless charging terminal through the second control strategy to roughly control the charging temperature of the wireless charging terminal.

[0042] In an embodiment of the present invention, obtaining the second identification information or temperature information of the wireless charging terminal through the vehicle-mounted communication device includes: sending a second identification information input request or a temperature information input request to the wireless charging terminal through the vehicle-mounted communication device, so that the wireless charging terminal sends the encrypted second identification information or temperature information to the vehicle head unit controller. After the vehicle head unit controller decrypts the encrypted second identification information or temperature information through the key information sent by the wireless charging terminal, the decrypted second identification information or temperature information is sent to the vehicle network bus through the vehicle-mounted communication device; obtaining the second identification information or temperature information through the network bus.

[0043] Specifically, when obtaining the second identification information or temperature information of the wireless charging terminal through the in-vehicle communication device, the in-vehicle communication device, such as in-vehicle Bluetooth, will actively send a second identification information input request or a temperature information input request to the wireless charging terminal. After receiving the second identification information input request or the temperature information input request, the wireless charging terminal will send the encrypted second identification information or temperature information to the vehicle head unit controller to ensure the security during the information transmission process. After decrypting the second identification information or temperature information, the vehicle head unit controller will send the decrypted second identification information or temperature information to the vehicle's network bus through in-vehicle Bluetooth, that is, convert the decrypted second identification information or temperature information into a CAN (Controller Area Network) signal and send it to the CAN bus. The vehicle wireless charging panel will intermittently capture the network bus to obtain the second identification information or temperature information through the network bus.

[0044] In an embodiment of the present invention, the second control strategy includes: obtaining vehicle speed information; controlling the rotation speed of the fan according to the vehicle speed information.

[0045] Specifically, the vehicle speed information includes the driving speed of the vehicle. During the charging process of the wireless charging terminal, heat dissipation is carried out through the fan. Since the noise generated by the fan motor will increase as the rotation speed of the fan increases, when the rotation speed of the fan is relatively large, it is easy to generate a relatively large fan motor noise. At this time, if the vehicle speed is relatively small and the in-vehicle noise is relatively large, it will reduce the user experience and affect driving safety. Therefore, when determining the rotation speed of the fan using the second control strategy, it is necessary to control the rotation speed of the fan according to the vehicle speed information to improve driving safety and enhance the user experience. By obtaining the vehicle speed information and controlling the rotation speed of the fan to increase as the driving speed of the vehicle increases, or decrease as the driving speed of the vehicle decreases, the rotation speed of the fan can be adapted to the driving speed of the vehicle. When the vehicle speed is relatively large, the noise of the vehicle driving can cover the noise of the fan motor, effectively enhancing the user experience and driving safety, and at the same time reducing the temperature of the wireless charging terminal during charging.

[0046] In an embodiment of the present invention, when the wireless connection between the wireless charging terminal and the vehicle wireless charging panel is successful, the method further includes: receiving a control instruction for limiting the charging power sent by the wireless charging terminal; adjusting the oscillation frequency of the coil in the vehicle wireless charging panel to a preset frequency to limit the charging power of the wireless charging terminal.

[0047] Specifically, since different wireless charging terminals can accept different maximum charging powers, when the wireless charging terminal detects that the current temperature is too high, it will send a control instruction to limit the charging power to the vehicle wireless charging panel to prevent the wireless charging terminal from overheating or even being damaged due to excessive charging power during charging. In the embodiment of the present invention, by obtaining the control instruction sent by the wireless charging terminal to limit the charging power, the oscillation frequency of the coil in the vehicle wireless charging panel is adjusted, and by adjusting, the oscillation frequency of the coil in the wireless charging panel is set to a preset frequency to limit the charging power of the wireless charging terminal, thereby protecting the hardware facilities of the wireless charging terminal and improving the charging efficiency of the wireless charging terminal.

[0048] According to the control method of the vehicle wireless charging panel in the embodiment of the present invention, when the wireless connection between the wireless charging terminal and the vehicle wireless charging panel is successful, the first identification information and temperature information of the wireless charging terminal are obtained. If the first identification information is the identification information in the preset identification library, it is determined that the control strategy for the charging temperature of the wireless charging terminal is the first control strategy, where the first control strategy includes the corresponding relationship between different temperature information and the rotation speed of the fan. According to the temperature information and the first control strategy, the rotation speed of the fan is determined to control the charging temperature of the wireless charging terminal, improving the heat dissipation effect of the fan and the charging efficiency of the wireless charging terminal while reducing power consumption and noise. Further, when determining the rotation speed of the fan using the first control strategy, the rotation speed of the fan is controlled according to the vehicle speed information to mask the noise of the fan motor, which can effectively improve the user experience and driving safety. Further, it is determined that the first identification information and the second identification information are the same, further improving the accuracy of the wireless charging terminal temperature control and the charging efficiency of the wireless charging terminal; further, the second identification information or temperature information of the wireless charging terminal is obtained through the vehicle-mounted communication device, and the encrypted second identification information or temperature information is sent to the vehicle-mounted controller. After the vehicle-mounted controller decrypts the encrypted second identification information or temperature information using the key information sent by the wireless charging terminal, the decrypted second identification information or temperature information is sent to the vehicle network bus through the vehicle-mounted communication device to ensure the security of the information transmission process; further, the rotation speed of the fan is controlled according to the vehicle speed information to balance the heat generated by the wireless charging terminal during charging and the heat dissipated by the fan, and is conducive to reducing power consumption and noise; further, when the wireless charging terminal detects that the current temperature is too high, the charging power of the wireless charging terminal is limited, protecting the hardware facilities of the wireless charging terminal.

[0049] A further embodiment of the present invention also discloses a control device for a vehicle wireless charging panel. The vehicle wireless charging panel includes a fan, and when the wireless charging terminal charges through the vehicle wireless charging panel, the fan is used to dissipate heat from the wireless charging terminal. Figure 2Schematic structural diagram of a control device for a vehicle wireless charging panel according to an embodiment of the present invention, as Figure 2 shown, the control device 10 of the vehicle wireless charging panel includes: an acquisition module 11, a determination module 12, and a control module 13. Among them, the acquisition module 11 is configured to acquire first identification information and temperature information of the wireless charging terminal when the wireless connection between the wireless charging terminal and the vehicle wireless charging panel is successful; the determination module 12 is configured to determine the first identification information and temperature information of the wireless charging terminal when the first identification information is the identification information in the preset identification library, where the first control strategy includes the correspondence between different temperature information and the rotation speed of the fan; the control module 13 determines the rotation speed of the fan according to the temperature information and the first control strategy.

[0050] In an embodiment of the present invention, after acquiring the first identification information of the wireless charging terminal, the determination module 12 is further configured to: if the first identification information is not the identification information in the preset identification library, determine that the control strategy for the charging temperature of the wireless charging terminal is the second control strategy; determine the rotation speed of the fan according to the second control strategy to control the charging temperature of the wireless charging terminal.
