[0050] The method embodiment provided in this embodiment can be executed on a terminal, a computer or a similar computing device. Taking running on a terminal as an example, Figure 1 is a hardware structure block diagram of a terminal for a control method of an in-vehicle wireless charger according to an embodiment of the present application. As Figure 1 shown, the terminal may include one or more ( Figure 1 only one is shown in the figure) processors 102 (the processor 102 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data.

[0052] The transmission device 106 is used to receive or send data via a network. Specific examples of the above-mentioned network may include a wireless network provided by a communication provider of the terminal. In one instance, the transmission device 106 includes a network adapter (abbreviated as NIC for Network Interface Controller), which can be connected to other network devices through a base station and thus communicate with the Internet. In one instance, the transmission device 106 can be a radio frequency (abbreviated as RF) module, which is used to communicate with the Internet wirelessly.

[0053] This embodiment provides a control method for an in-vehicle wireless charger. Figure 2 is a flowchart of a control method for an in-vehicle wireless charger according to an embodiment of the present application, as Figure 2 shown, this process includes the following steps:

[0054] Step S210, obtain the initial charging power corresponding to the terminal device to be charged; the initial charging power is the maximum safe charging power that the terminal device to be charged can currently accept.

[0055] First, the vehicle-mounted controller obtains the maximum safe charging power that the terminal device to be charged (such as a mobile phone, tablet, etc.) can currently accept as the initial charging power. This initial charging power is jointly determined by the battery state of the terminal device, the manufacturer's recommendations, and the charging ability of the wireless charger. Through this step, it is ensured that the power at the beginning of the charging process is safe and efficient, and at the same time, the charging speed can be maximized.

[0056] Step S220, control the in-vehicle wireless charger to charge the terminal device to be charged at the initial charging power.

[0057] The above in-vehicle wireless charger can start charging the terminal device to be charged according to the initial charging power determined in step S210. Specifically, the in-vehicle wireless charger can include a battery control module, a wireless charging control module, and a wireless charging board; the vehicle head unit controller sends the obtained initial charging power to the battery control module to prompt the battery control module how much power should be supplied to the wireless charging control module; the battery control module releases appropriate voltage power to the wireless charging control module, and starts to provide power support to the in-vehicle wireless charging board by the wireless charging control module; the wireless charging board receives the voltage power instruction indicating that wireless charging can be provided from the wireless charging control module, and starts charging the terminal device in response to this instruction.

[0058] Step S230, during the process of charging the terminal device to be charged, detect the first real-time temperature of the in-vehicle wireless charger and the second real-time temperature of the terminal device to be charged.

[0059] Among them, the vehicle head unit controller continuously detects the first real-time temperature of the in-vehicle wireless charger during the charging process, and obtains the second real-time temperature monitored by the terminal device itself uploaded to the cloud, so as to monitor the temperature changes of the in-vehicle wireless charger and the terminal device to be charged in real time during the charging process.

[0060] Step S240, in the case where it is detected that the first real-time temperature exceeds the preset first temperature threshold and / or the second real-time temperature exceeds the preset second temperature threshold, obtain the real-time charging power of the terminal device to be charged, and reduce the initial charging power to the first adapted charging power according to the first real-time temperature, the second real-time temperature, and the real-time charging power.

[0061] The above first temperature threshold refers to the temperature threshold that can be reached by the in-vehicle wireless charger when it is in a temperature stable state, and the above second temperature threshold refers to the temperature threshold that can be reached by the terminal device to be charged when it is in a temperature stable state; the first temperature threshold and the second temperature threshold can be set in advance according to the actual situation. For example, the first temperature threshold can be set to 26 °C, and the second temperature threshold can be set to 25 °C. If it is detected that the first real-time temperature of the in-vehicle wireless charger exceeds the preset first temperature threshold, or the second real-time temperature of the terminal device to be charged exceeds the preset second temperature threshold (or both at the same time), then perform the following operations.

[0062] Obtain the real-time charging power of the terminal device to be charged; comprehensively consider the first real-time temperature, the second real-time temperature, and the real-time charging power, calculate a first adapted charging power that ensures safety and is as efficient as possible, and reduce the initial charging power to the first adapted charging power, so that when the temperature is abnormal, overheating can be prevented by reducing the power, and at the same time, the charging efficiency can be maintained as much as possible.

[0063] It should also be supplemented and explained that, in this embodiment, in addition to dynamically adjusting the charging power of the in-vehicle wireless charger in the above manner to reduce the charging rate by reducing the charging power, methods such as refrigeration and cooling can also be combined to implement a reasonable temperature monitoring and management strategy, effectively reducing potential safety hazards caused by overheating.

[0064] Step S250: Control the in-vehicle wireless charger to continue charging the terminal device to be charged at the first adapted charging power.

[0065] Among them, the in-vehicle wireless charger continues to charge the terminal device to be charged at the first adapted charging power, and during this process, the vehicle-mounted computer controller continues to monitor the temperature and charging status for further adjustment if necessary.

[0066] In the related art, the wireless charging function directly provides the highest voltage and cannot adapt to the current status of the terminal device, resulting in damage to the battery life and the lifespan of the terminal device due to high-power charging. Based on this, in the above control method of the in-vehicle wireless charger, when the terminal device and / or the charging board is overheated, the charging power of the charging board is adjusted by combining the temperature and the real-time charging power, so that the in-vehicle wireless charger can not only charge the terminal device quickly and effectively during the charging process, but also respond to changes in temperature and power in a timely manner, ensuring the safety of the terminal device and the charger. Moreover, by dynamically adjusting the charging power, a balance point is found between charging efficiency and safety, thus realizing a control method for an adaptable variable-voltage wireless charging board and solving the problem that the use of an in-vehicle wireless charger is likely to damage the battery life of the terminal device.

[0067] In some of these embodiments, the above-mentioned obtaining the initial charging power corresponding to the terminal device to be charged may further include the following steps:

[0068] Obtain the vehicle-mounted computer database stored on the cloud server; based on the vehicle-mounted computer database, obtain the historical charging data for the terminal device to be charged, and determine the initial charging power according to the historical charging data.

[0069] The above-mentioned vehicle-mounted computer database refers to a database used to store relevant data of the currently applied vehicle model and the charging data of the user terminal device on this model of vehicle. In order for the vehicle-mounted computer controller to pull the relevant data in the vehicle-mounted computer database in real time, in this embodiment, the vehicle-mounted computer database is stored in the cloud server.

[0070] Specifically, in the in-vehicle computer database, find the historical charging data table related to the terminal device to be charged. For example, the historical charging data of the device can be queried according to the unique identifier of the terminal device (such as device ID, license plate number, etc.). The historical charging data should include detailed information such as the amount of electricity, charging time, charging voltage, and charging current for each charge.

[0071] Conduct statistical analysis on the queried historical charging data, including the number of charges, average charging time, average charging power, etc., and then analyze the charging habits and charging requirements of the terminal device. Finally, based on the historical charging data and the charging requirements of the terminal device, use a suitable algorithm or model to determine the initial charging power. For example, machine learning algorithms can be considered to train the historical data to predict a more accurate initial charging power, or the threshold range of the initial charging power can be set according to empirical rules or industry standards.

[0072] In practical applications, the charging power can be dynamically adjusted according to the real-time charging status and charging requirements of the terminal device. For example, a higher charging power is adopted when the battery level is low to quickly replenish the power, and the charging power is reduced when the battery is nearly fully charged to protect the battery life.

[0073] Through the above embodiments, it is possible to obtain the data in the in-vehicle computer database stored on the cloud server and determine the initial charging power of the terminal device to be charged based on these data, which helps to improve the charging efficiency and protect the battery life.

[0074] In some of these embodiments, the control method of the above in-vehicle wireless charger further includes the following steps:

[0075] During the charging process of the terminal device to be charged, obtain the second real-time temperature uploaded by the terminal device to the terminal database; the second real-time temperature is the real-time temperature of the terminal device to be charged, and the terminal database is stored on the cloud server. Among them, the terminal device to be charged can use devices such as its own installed battery management module and temperature sensor to monitor its own temperature in real time and upload the second real-time temperature monitored during the charging process to the terminal database, so that the in-vehicle computer controller can pull the second real-time temperature from the terminal database stored in the cloud in real time.

[0076] Through the above embodiments, both the terminal database and the in-vehicle computer database are stored on the cloud server, so that the terminal device and the in-vehicle computer data are no longer linked but completely synchronized, avoiding the link time-consuming between different databases. At the same time, the data in the database is uniformly distributed from the cloud, avoiding the theft of data during the security blank period caused by the link.

[0077] In some of these embodiments, when it is detected that the first real-time temperature exceeds a preset first temperature threshold and / or the second real-time temperature exceeds a preset second temperature threshold, the real-time charging power of the terminal device to be charged is obtained, and based on the first real-time temperature, the second real-time temperature, and the real-time charging power, the initial charging power is reduced to a first adapted charging power. The method may further include the following steps:

[0078] Obtain the battery health of the terminal device to be charged, and determine the second temperature threshold according to the battery health; when it is detected that the first real-time temperature exceeds the first temperature threshold and / or the second real-time temperature exceeds the second temperature threshold, obtain the real-time charging power of the terminal device to be charged, and based on the first real-time temperature, the second real-time temperature, the real-time charging power, and the battery health, reduce the initial charging power to a first adapted charging power.

[0079] Among them, for the terminal device to be charged, different battery health levels have different tolerances for charging voltage and temperature. Therefore, in this embodiment, the charging voltage and temperature most suitable for the current state of the terminal device can be adjusted according to the voltage and temperature tolerance levels represented by the current battery health of the user terminal device.

[0080] In some of these embodiments, during the charging of the terminal device to be charged, the control method of the in-vehicle wireless charger further includes the following steps:

[0081] Obtain the vehicle computer database stored on the cloud server; based on the vehicle computer database, obtain the device usage habit data and historical charging data for the terminal device to be charged; calculate the charging habit data according to the historical charging data; when it is detected that the device usage habit data is greater than a preset usage duration threshold and / or the charging habit data is greater than a preset charging times threshold, obtain the charging power in the preset fast charging mode, and determine a second adapted charging power based on the charging power in the preset fast charging mode; adjust the initial charging power to the second adapted charging power; control the in-vehicle wireless charger to continue charging the terminal device to be charged at the second adapted charging power.

[0082] It should be noted that different terminal devices have different usage habits and charging habits, and the applicable charging methods are also different. Specifically, based on the comparison results between the statistically obtained device usage habit data and the usage duration threshold, and the comparison results between the statistically obtained charging habit data and the charging times threshold, it is determined whether the current terminal device user is a heavy user. The usage duration threshold and the charging times threshold can be set in advance. More specifically, if it is detected that the device usage habit data is greater than the usage duration threshold and / or the charging habit data is greater than the charging times threshold, it indicates that the terminal device user is a heavy user. For example, if the continuous usage time each time is more than 1 hour, there will be phenomena such as continuous power consumption, rapid increase in device temperature, and frequent charging. At this time, a fast charging method that protects the terminal device is adopted for the terminal device to protect the battery life of the terminal device as much as possible.

[0083] In some of these embodiments, determining the second adaptive charging power based on the charging power in the preset fast charging mode includes:

[0084] Obtain the current core task for the terminal device to be charged, and detect the task type of the current core task; based on the task type and the charging power in the preset fast charging mode, determine the second adaptive charging power.

[0085] Among them, the task types of the current core task may include: entertainment browsing type, work processing type, and security type. Specifically, if it is detected that the content of the current core task of the user's operation on the terminal device to be charged is a task belonging to the entertainment browsing type such as browsing web content or listening to music, a charging mode with battery protection as the main and charging speed as the auxiliary is determined. Then, based on this charging mode and combined with the charging power in the preset fast charging mode, the initial charging power is adjusted to the second adaptive charging power. If it is detected that the content of the current core task of the terminal device to be charged is a task belonging to the work task type such as normal work processing, a charging mode with a 50% share of speed and battery protection is set, and based on this charging mode and the charging power in the preset fast charging mode, the charging power output by the in-vehicle wireless charger is dynamically adjusted. If the detected current core task is a task type related to security such as health emergency, a charging mode with speed as the main and battery health as the auxiliary is set, and the charging power is dynamically adjusted.

[0086] Through the above embodiments, a method of dynamically adjusting the charging strategy according to the device usage habit, charging habit, and the user's current core task is realized, further improving the adaptability of the in-vehicle wireless charger to different application scenarios.

[0087] In some of these embodiments, the above control method of the in-vehicle wireless charger further includes:

[0088] Obtain the in-vehicle ambient temperature; during the process of controlling the in-vehicle wireless charger to charge the to-be-charged terminal device at the initial charging power or the first adapted charging power, control the in-vehicle refrigeration device to cool the in-vehicle wireless charger and / or the to-be-charged terminal device according to the first real-time temperature, the second real-time temperature and the in-vehicle ambient temperature.

[0089] To ensure temperature stability, during the charging process, the first real-time temperature of the in-vehicle wireless charger, the second real-time temperature of the to-be-charged terminal device, and the in-vehicle ambient temperature can also be monitored and detected to ensure that the first real-time temperature is stable within a first stable temperature range of about 26°C, the second real-time temperature is stable within a second stable temperature range of 15°C to 25°C, and the in-vehicle ambient temperature is stable within a third stable temperature range of about 26°C.

[0090] Among them, if it is detected that the first real-time temperature, the second real-time temperature, and / or the in-vehicle ambient temperature exceed the corresponding temperature thresholds, it indicates that the temperature of the in-vehicle wireless charger and / or the to-be-charged terminal device exceeds the optimal temperature at this time, or the in-vehicle ambient temperature is too high, which is likely to cause both the wireless charging device and the terminal device to be affected by heat, resulting in a decrease in heat dissipation efficiency. Therefore, the air direction can be adjusted by controlling in-vehicle refrigeration devices such as air conditioners to cool the in-vehicle wireless charger and / or the to-be-charged terminal device. Or, in another embodiment, the refrigerant can also be shunted through the co-driver's refrigerator refrigeration device in the vehicle to cool the wireless charging board in direct contact with the terminal device.

[0091] Through the above embodiments, the temperature of the in-vehicle wireless charger, the ambient temperature, and the terminal device are coordinated in a three-way temperature linkage, maintaining the temperature control of the in-vehicle wireless charger to meet the vehicle body's own requirements, so as to avoid spontaneous combustion caused by high temperature. At the same time, it can also ensure a pleasant ambient temperature and an appropriate charging temperature for the terminal device, thereby avoiding the problems of further damaging the terminal device battery or causing the terminal device to become an ignition point.

[0092] In some of these embodiments, reducing the initial charging power to the first adapted charging power according to the first real-time temperature, the second real-time temperature, and the real-time charging power may further include the following steps:

[0093] Send the first real-time temperature, the second real-time temperature, and the in-vehicle ambient temperature to the in-vehicle screen for display; in response to the control instruction received by the in-vehicle screen, reduce the initial charging power to the first adapted charging power according to the first real-time temperature, the second real-time temperature, the in-vehicle ambient temperature, and the real-time charging power.

[0094] Among them, the collected first real-time temperature data, second real-time temperature data, in-vehicle ambient temperature data, and power data are displayed on the in-vehicle screen so that the driver or passenger can intuitively see the current temperature status and charging progress. The in-vehicle screen provides a user interface (UI) that allows users to view the current status and send control instructions. When the user sends a control instruction through the touch screen or other means, according to the received control instruction and the current first real-time temperature, second real-time temperature, second real-time temperature, and real-time charging power, the corresponding power adjustment algorithm is executed. This algorithm comprehensively considers factors such as temperature safety thresholds, battery health status, charging efficiency, and user preferences, and calculates the first adapted charging power. Finally, according to the calculated first adapted charging power, the output power of the in-vehicle wireless charger is adjusted.

[0095] The adjusted charging power and new temperature data are continuously collected in real time and displayed on the in-vehicle screen, and the temperature and charging status are continuously monitored to ensure the safety and efficiency of the entire charging process. Through the above embodiments, the interaction between the terminal device for transmitting data and the in-vehicle screen is realized, further improving the application flexibility.

[0096] The present application will be described and illustrated below in conjunction with specific embodiments. Figure 3 It is a flowchart of another control method for an in-vehicle wireless charger according to an embodiment of the present application, as Figure 3 shown, and this process includes the following steps:

[0097] Step S301, the terminal device sends the configuration data such as the highest charging voltage, the best charging temperature, and humidity that are most suitable for itself, which are calculated in real time, to the cloud server. Among them, the terminal device can calculate this type of configuration data through the battery management function installed on itself.

[0098] Step S302, the cloud server sends the configuration data to the vehicle-mounted controller that the terminal device is currently riding in or about to ride in. This step can be achieved through positioning or IP address.

[0099] Step S303, the vehicle-mounted controller sends the received highest charging voltage to the battery control module, indicating how much power the battery control module should supply to the wireless charging control module.

[0100] Step S304, the battery control module releases the appropriate voltage power to the wireless charging control module and starts to provide power support to the wireless charging board.

[0101] Step S305, the wireless charging board receives the voltage power instruction from the wireless charging control module that can provide wireless charging and starts to charge the terminal device.

[0102] Step S306, during the charging process, the first real-time temperature of the wireless charging pad itself can be transmitted back to the vehicle head unit controller through the original circuit.

[0103] Step S307, the terminal device uses the wireless charging pad to charge, and uploads the second real-time temperature of the terminal device during the charging process to the terminal database stored in the cloud server.

[0104] Step S308, the vehicle head unit controller reads the data in the terminal database and the vehicle head unit database from the cloud server, and obtains the first real-time temperature, the second real-time temperature, and the optimal charging temperature of the terminal device.

[0105] Step S309, the vehicle head unit controller transmits the first real-time temperature, the second real-time temperature, and the ambient temperature to the in-vehicle screen for display at the same time, and the screen prompts the current temperature.

[0106] Step S310, detect whether the first real-time temperature, the second real-time temperature, and the in-vehicle ambient temperature are in a temperature stable state. If so, continue to monitor the real-time temperature.

[0107] Step S311, if the judgment result of the above step S310 is no, the in-vehicle screen provides operation buttons to remind the user whether to continue charging when the temperature of the wireless charging pad and the terminal device exceeds the optimal temperature. Among them, the operation buttons include a first button of "Yes (air conditioner cools down)", and a second button of "No (stop charging and continue charging after natural cooling)".

[0108] Step S312, synchronize the operation instruction received by the in-vehicle screen to the air conditioner control system and execute according to the instruction selected by the user. Among them, if the operation instruction is the first operation instruction triggered by the user clicking the first button, the air conditioner control system realizes the three-party temperature through refrigeration; if the operation instruction is the second operation instruction triggered by the user clicking the second button, the refrigeration operation is not executed.
