Description

Technical Field

[0001] The present invention relates to the technical field of intelligent vehicle machines, and particularly relates to a vehicle-mounted wireless charging heat dissipation method, device, system and medium. Background Art

[0002] With the improvement of the performance of the vehicle power supply system and the electronic control unit, the modern vehicle electrical system can stably provide a voltage and power suitable for wireless charging. The vehicle electronic control unit can accurately manage the charging process to achieve overcharge, overcurrent and overheat protection, ensuring the safety and stability of charging. Vehicle-mounted wireless chargers have become a standard configuration in mainstream vehicle models. Users are increasingly concerned about the high-power wireless charging performance of mobile phones, and the experience of the heat dissipation performance of wireless charging mobile phones is also more obvious. Currently, the heat dissipation devices of some wireless chargers are realized by the heat dissipation fans installed on the wireless chargers. Usually, a temperature sensor is provided on the charging base of the wireless charger to detect the temperature of mobile devices such as mobile phones and tablets placed on the charging base, and then the rotation speed of the heat dissipation fan is controlled according to the temperature to achieve an intelligent heat dissipation effect. However, due to different manufacturing processes, the temperature rise situations of different brands of mobile devices in the market are very different, and the accuracy of the temperature detected by the temperature sensor depends on the placement position of the mobile device, resulting in the inability to accurately obtain the real-time temperature of each mobile device, so that the air volume output by the controlled heat dissipation fan does not match the actual heat dissipation requirement, resulting in poor heat dissipation effect. Summary of the Invention

[0003] In view of this, the present invention provides a vehicle-mounted wireless charging heat dissipation method, device, system and medium to solve the problem of poor heat dissipation effect of vehicle-mounted wireless charging.

[0004] In a first aspect, the present invention provides a vehicle-mounted wireless charging heat dissipation method applied to a wireless charging assembly. The method includes: obtaining a first control signal, which is generated according to the temperature information of a mobile device, and the temperature information is detected by a temperature detection element inside the mobile device and is the information sent by the mobile device; sending the first control signal to a first radiator to control the first radiator to dissipate heat from the mobile device.

[0005] According to the above technical means, the first control signal obtained by the wireless charging assembly is generated from the temperature information detected by the temperature detection element inside the mobile device, and this temperature information is directly sent by the mobile device, thereby ensuring the accuracy of the real-time temperature of the mobile device. Furthermore, the control signal generated according to the more accurate temperature of the mobile device is more accurate, so as to control the operation of the first radiator connected to the wireless charging assembly, making the heat dissipation effect of the first radiator better match the real-time temperature of the mobile device, and significantly improving the heat dissipation effect when the mobile device is wirelessly charged.

[0006] In some alternative embodiments, the obtaining of the first control signal includes: obtaining temperature information of the mobile device, where the temperature information is detected by a temperature detection component inside the mobile device and is information sent by the mobile device; generating the first control signal according to the temperature information.

[0007] According to the above technical means, the wireless charging assembly can obtain the temperature information into its own storage space, enabling the wireless charging assembly itself to execute the strategy of generating the first control signal.

[0008] In some alternative embodiments, the obtaining of the temperature information of the mobile device includes: receiving the temperature information sent by the mobile device, or receiving the temperature information sent by the in-vehicle computer, where the temperature information in the in-vehicle computer is sent by the mobile device.

[0009] According to the above technical means, the mobile device can directly establish a communication connection with the wireless charging assembly or with the in-vehicle computer, so that the temperature information of the mobile device can be transmitted to the in-vehicle computer through a private communication protocol, and then sent to the wireless charging assembly by the in-vehicle computer based on the vehicle CAN bus, or directly sent to the wireless charging assembly by the mobile device based on a custom communication protocol.

[0010] In some alternative embodiments, the obtaining of the first control signal includes: receiving the first control signal sent by the in-vehicle computer, where the first control signal is generated by the in-vehicle computer according to the temperature information, and the temperature information in the in-vehicle computer is sent by the mobile device.

[0011] According to the above technical means, the temperature information of the mobile device can be transmitted to the in-vehicle computer through a private communication protocol, so that the first control signal is generated by the in-vehicle computer and then sent to the wireless charging assembly through the CAN bus, avoiding the execution of a more complex strategy by a processor with lower performance in the wireless charging assembly, and enabling a better-performing in-vehicle computer to execute the control strategy, improving the control efficiency and balancing the allocation of in-vehicle computing resources.

[0012] In some alternative embodiments, the step of generating the first control signal according to the temperature information includes: determining the temperature range where the temperature information is located based on a plurality of preset temperature thresholds; if the current temperature range is not the highest temperature range, obtaining the target timing period, target control information, and target control coefficient of the current temperature range; generating a first control signal output within the current target timing period based on the target control information; at the end of the current target timing period, re-determining the temperature range where the temperature information is located based on a plurality of preset temperature thresholds; if the temperature information is still within the current temperature range and is greater than the temperature before the current target timing period, amplifying the target control information based on the target control coefficient, and generating a first control signal output within the next target timing period based on the amplified control information; if the temperature information is still within the current temperature range and is less than or equal to the temperature before the current target timing period, using the control signal output within the current target timing period as the first control signal output within the next target timing period.

[0013] According to the above technical means, different temperature ranges are set for different temperatures for control. Among them, the control information corresponding to the higher temperature range can make the heat dissipation effect stronger. When the temperature falls within a certain range, the radiator is first started using the predefined target control information of that range. After a timing period, the temperature change of the mobile device is re-determined. If the temperature range where the temperature information of the mobile device is located does not change and the temperature rises slightly, the control signal is enhanced using the target control coefficient to enhance the heat dissipation effect. If the temperature range where the temperature information of the mobile device is located does not change and the temperature drops slightly, the control signal of the previous timing period is used to continue heat dissipation. Through this solution, an adaptive control method for a radiator is realized, which not only makes the heat dissipation effect more matched with the temperature of the mobile device, but also reduces the energy consumption of the radiator and the cost.

[0014] In some alternative embodiments, after re-determining the temperature range where the temperature information is located based on a plurality of preset temperature thresholds at the end of the current target timing period, it further includes: if the temperature information is in a higher temperature range and is not the highest temperature range, generating the first control signal based on the timing period, control information, and control coefficient of the higher temperature range; if the temperature information is in a lower temperature range, generating the first control signal based on the timing period, control information, and control coefficient of the lower temperature range.

[0015] According to the above technical means, if after a timing cycle, the temperature change of the mobile device is rejudged, and if the temperature range where the temperature information of the mobile device is located changes, the same control process as above is executed again through the control information and control coefficient of the new range, further improving the adaptive control ability of the radiator.

[0016] In some alternative embodiments, the step of generating the first control signal according to the temperature information further includes: if the current temperature range is the highest temperature range, stop charging; obtain the timing cycle and control information of the highest temperature range; generate the first control signal output within the timing cycle of the highest temperature range based on the control information of the highest temperature range; at the end of the current timing cycle of the highest temperature range, rejudge the temperature range where the temperature information is located based on multiple preset temperature thresholds; if the temperature information is still within the highest temperature range, repeat the step of generating the first control signal output within the timing cycle of the highest temperature range based on the control information of the highest temperature range; if the temperature information is in a lower temperature range, generate the first control signal based on the timing cycle, control information, and control coefficient of the lower temperature range.

[0017] According to the above technical means, if the temperature of the mobile hot standby reaches the preset highest temperature range, it means that the temperature of the mobile device is too high. At this time, charging should be stopped, and heat dissipation control should be carried out according to the timing cycle and control signal of the high temperature range to increase the cooling speed of the mobile device.

[0018] In a second aspect, the present invention provides a vehicle-mounted wireless charging heat dissipation method applied to a vehicle-mounted computer. The method includes: sending a temperature request to a mobile device; receiving the temperature information fed back by the mobile device in response to the temperature request, where the temperature information is detected by a temperature detection element inside the mobile device; generating a first control signal based on the temperature information; sending the first control signal to a wireless charging assembly so that the wireless charging assembly sends the first control signal to a first radiator to control the first radiator to dissipate heat from the mobile device.

[0019] According to the above technical means, the temperature information of the mobile device can be transmitted to the vehicle-mounted computer through a private communication protocol, so that the first control signal is generated by the vehicle-mounted computer and then sent to the wireless charging assembly through the CAN bus, so as to avoid a relatively low-performance processor in the wireless charging assembly from executing a more complex strategy, and instead, the control strategy is executed by a vehicle-mounted computer with better performance, improving the control efficiency and balancing the allocation of in-vehicle computing resources.

[0020] In some alternative embodiments, the method further includes: generating a second control signal based on the temperature information; and sending the second control signal to a second radiator to control the second radiator to dissipate heat from the mobile device.

[0021] According to the above technical means, in addition to the radiator directly connected to the wireless charging assembly, an additional independent second radiator can be deployed in the vehicle. The second radiator is directly controlled by the in-vehicle computer, so that the in-vehicle computer can generate a second control signal based on the temperature information and control the second radiator to dissipate heat from the mobile device through the second control signal, further expanding the application scenario of the wireless charging heat dissipation solution and improving the heat dissipation capacity.

[0022] In some alternative embodiments, a vehicle air conditioner outlet is provided near the charging base of the wireless charging assembly, and the second radiator is the vehicle air conditioner.

[0023] According to the above technical means, in the present invention, a vehicle air conditioner outlet is provided near the charging base of the wireless charging assembly, and the in-vehicle computer co-controls the air outlet of the air conditioner to dissipate heat for wireless charging. This not only realizes the heat dissipation function but also reduces the installation of the radiator. The heat dissipation solution can be implemented using the original equipment of the vehicle, reducing the manufacturing cost of the vehicle.

[0024] In some alternative embodiments, the step of generating the first control signal or the second control signal based on the temperature information includes: determining the temperature range where the temperature information is located based on a plurality of preset temperature thresholds; if the current temperature range is not the highest temperature range, obtaining the target timing period, target control information, and target control coefficient of the current temperature range; generating the first control signal or the second control signal output within the current target timing period based on the target control information; at the end of the current target timing period, re-determining the temperature range where the temperature information is located based on the plurality of preset temperature thresholds; if the temperature information is still within the current temperature range and greater than the temperature before the current target timing period, amplifying the target control information based on the target control coefficient and generating the first control signal or the second control signal output within the next target timing period based on the amplified control information; if the temperature information is still within the current temperature range and less than or equal to the temperature before the current target timing period, using the control signal output within the current target timing period as the first control signal or the second control signal output within the next target timing period.

[0025] In some alternative embodiments, after re-determining the temperature range where the temperature information is located based on a plurality of preset temperature thresholds at the end of the current target timing period, the following steps are further included: If the temperature information is in a higher temperature range and not in the highest temperature range, generate the first control signal or the second control signal based on the timing period, control information, and control coefficient of the higher temperature range; If the temperature information is in a lower temperature range, generate the first control signal or the second control signal based on the timing period, control information, and control coefficient of the lower temperature range.

[0026] In some alternative embodiments, the step of generating the first control signal according to the temperature information further includes: If the current temperature range is the highest temperature range, stop charging; Obtain the timing period and control information of the highest temperature range; Generate the first control signal or the second control signal output within the timing period of the highest temperature range based on the control information of the highest temperature range; At the end of the current timing period of the highest temperature range, re-determine the temperature range where the temperature information is located based on a plurality of preset temperature thresholds; If the temperature information is still in the highest temperature range, repeat the step of generating the first control signal or the second control signal output within the timing period of the highest temperature range based on the control information of the highest temperature range; If the temperature information is in a lower temperature range, generate the first control signal or the second control signal based on the timing period, control information, and control coefficient of the lower temperature range.

[0027] In a third aspect, the present invention provides a vehicle-mounted wireless charging heat dissipation device applied to a wireless charging assembly. The device includes: a control signal acquisition module, configured to acquire a first control signal, where the first control signal is generated according to the temperature information of a mobile device, and the temperature information is information detected by a temperature detection element inside the mobile device and sent by the mobile device; a control sending module, configured to send the first control signal to a first radiator to control the first radiator to dissipate heat from the mobile device.

[0028] In a fourth aspect, the present invention provides a vehicle-mounted wireless charging heat dissipation device applied to a vehicle-mounted computer. The device includes: a requested temperature module, configured to send a temperature request to a mobile device; a temperature receiving module, configured to receive the temperature information fed back by the mobile device in response to the temperature request, where the temperature information is detected by a temperature detection element inside the mobile device; a control signal generation module, configured to generate a first control signal based on the temperature information; a control forwarding module, configured to send the first control signal to a wireless charging assembly so that the wireless charging assembly sends the first control signal to a first radiator to control the first radiator to dissipate heat from the mobile device.

[0029] Fifth aspect, the present invention provides a vehicle-mounted wireless charging and heat dissipation system, including a vehicle computer, a wireless charging assembly, and a mobile device; the vehicle computer, the wireless charging assembly, and the mobile device are communicatively connected to each other; the wireless charging assembly includes a first computer instruction for executing the method according to any one of the first aspect; the vehicle computer includes a second computer instruction for executing the method according to any one of the second aspect.

[0030] Sixth aspect, the present invention provides a computer-readable storage medium, on which computer instructions are stored, and the computer instructions are used to cause a computer to execute the method according to any one of the first aspect and the second aspect.

[0031] The technical solution provided by the present invention has the following advantages:

[0032] (1) According to the above technical means, the first control signal obtained by the wireless charging assembly is generated from the temperature information detected by the internal temperature detection element of the mobile device, and this temperature information is directly sent by the mobile device, thus ensuring the accuracy of the real-time temperature of the mobile device. Furthermore, the control signal generated based on the more accurate temperature of the mobile device is more accurate, thereby controlling the operation of the first radiator connected to the wireless charging assembly, so that the heat dissipation effect of the first radiator has a higher matching degree with the real-time temperature of the mobile device, significantly improving the heat dissipation effect during wireless charging of the mobile device.

[0033] (2) According to the above technical means, the wireless charging assembly can obtain the temperature information into its own storage space, enabling the wireless charging assembly itself to execute the strategy of generating the first control signal.

[0034] (3) According to the above technical means, the mobile device can directly establish a communication connection with the wireless charging assembly or with the vehicle computer, so that the temperature information of the mobile device can be transmitted to the vehicle computer through a private communication protocol, and then sent to the wireless charging assembly by the vehicle computer based on the vehicle CAN bus, or directly sent to the wireless charging assembly by the mobile device based on a custom communication protocol.

[0035] (4) According to the above technical means, the temperature information can be transmitted from the mobile device to the vehicle computer through a private communication protocol, so that the first control signal is generated by the vehicle computer and then sent to the wireless charging assembly through the CAN bus, avoiding the execution of relatively complex strategies by the processor with lower performance in the wireless charging assembly, and instead, the control strategy is executed by the vehicle computer with better performance, improving the control efficiency and balancing the allocation of in-vehicle computing resources.

[0036] (5) According to the above technical means, different temperature ranges are set for different temperatures for control. Among them, the control information corresponding to the temperature range with a higher temperature can make the heat dissipation effect stronger. When the temperature falls within a certain range, first, the radiator is started using the target control information predefined for this range. After a timing cycle, the temperature change of the mobile device is judged again. If the temperature range where the temperature information of the mobile device is located does not change and the temperature rises slightly, the control signal is enhanced using the target control coefficient to enhance the heat dissipation effect. If the temperature range where the temperature information of the mobile device is located does not change and the temperature drops slightly, the control signal of the previous timing cycle is continued for heat dissipation. Through this solution, an adaptive control method for the radiator is realized, which not only makes the heat dissipation effect more matched with the temperature of the mobile device, but also reduces the energy consumption of the radiator and the cost.

[0037] (6) According to the above technical means, if after a timing cycle, the temperature change of the mobile device is judged again. If the temperature range where the temperature information of the mobile device is located changes, the same control process as above is executed again through the control information and control coefficient of the new range, further improving the adaptive control ability of the radiator.

[0038] (7) According to the above technical means, if the temperature of the mobile hot standby reaches the preset highest temperature range, it means that the temperature of the mobile device is too high. At this time, charging should be stopped, and the timing cycle and control signal of the high temperature range are used for heat dissipation control to increase the cooling speed of the mobile device.

[0039] (8) According to the above technical means, the temperature information can be transmitted from the temperature information of the mobile device to the in-vehicle computer through a private communication protocol. Thus, the first control signal is generated by the in-vehicle computer and sent to the wireless charging assembly through the CAN bus, so as to avoid the relatively complex strategy being executed by the processor with lower performance in the wireless charging assembly, and the control strategy is executed by the in-vehicle computer with better performance, improving the control efficiency and balancing the allocation of in-vehicle computing resources.

[0040] (9) According to the above technical means, in addition to the radiator directly connected to the wireless charging assembly, an additional independent second radiator can also be deployed in the vehicle. The second radiator is directly controlled by the in-vehicle computer. Thus, the in-vehicle computer can generate a second control signal according to the temperature information and control the second radiator to dissipate heat for the mobile device through the second control signal, further expanding the application scenario of the wireless charging heat dissipation solution and improving the heat dissipation ability.

[0041] (10) According to the above technical means, an air outlet of a vehicle-mounted air conditioner is arranged near the charging base of the wireless charging assembly of the present invention. The in-vehicle computer controls the air outlet of the air conditioner through linkage to dissipate heat for the wireless charging, which not only realizes the heat dissipation function, but also reduces the installation of the radiator. The heat dissipation solution can be realized by using the original equipment of the vehicle, and the manufacturing cost of the vehicle is reduced. Description of the Drawings

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0053] According to an embodiment of the present invention, an embodiment of a vehicle-mounted wireless charging heat dissipation method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0054] In this embodiment, a vehicle-mounted wireless charging heat dissipation method is provided, which is applied to a wireless charging assembly. Figure 1 It is a flowchart of a vehicle-mounted wireless charging heat dissipation method according to an embodiment of the present invention. The process includes the following steps:

[0055] Step S101: Obtain a first control signal, which is generated according to the temperature information of the mobile device. The temperature information is detected by a temperature detection element inside the mobile device and is the information sent by the mobile device.

[0056] Step S102: Send the first control signal to a first radiator to control the first radiator to dissipate heat from the mobile device.

[0057] Specifically, the wireless charging assembly refers to the overall wireless charging device including a wireless charging base, a wireless charging circuit, and a wireless charging processor. The first radiator refers to a radiator directly connected to the wireless charging assembly circuit and controlled by the wireless charging assembly, including but not limited to a cooling fan, liquid cooling, oil cooling, etc. If it is a cooling fan, the heat dissipation capacity of the radiator can be improved by increasing the fan speed. If it is a liquid radiator, the heat dissipation capacity of the radiator can be improved by increasing the liquid flow rate.

[0058] In an embodiment of the present invention, a wireless charging assembly obtains a first control signal, which is used to control a first radiator to control the rotation speed, flow rate, etc. according to a predetermined strategy, so as to achieve a predetermined heat dissipation effect. Among them, the temperature information source of the first control signal does not come from the temperature sensor equipped on the wireless charging assembly, but from the mobile device itself, such as the temperature detection function built in a mobile phone or a tablet computer. Thus, mobile devices such as mobile phones and tablets send out the temperature information detected by themselves through wireless communication, and then generate a first control signal according to the temperature information sent by the mobile device. The first control signal can be generated by the wireless charging assembly processor executing a generation strategy internally according to the temperature information, or can be a first control signal generated by an in-vehicle computer receiving the temperature information of the mobile device, or can also be a first control signal generated by the mobile device itself according to the temperature information. As long as the final first control signal can reach the wireless charging assembly and be forwarded by the wireless charging assembly to the first radiator, the present invention does not specifically limit the generation location of the first control signal. The first control signal can be a duty cycle signal, a current signal, a voltage signal, etc. The specific signal type is related to the type of the radiator to be controlled and the control method, and the embodiments of the present invention do not make specific limitations.

[0059] According to the above technical means, the first control signal obtained by the wireless charging assembly is generated from the temperature information detected by the internal temperature detection element of the mobile device, and the temperature information is directly sent by the mobile device, so as to ensure the real-time temperature accuracy of the mobile device. Furthermore, the control signal generated according to the more accurate temperature of the mobile device is more accurate, so as to control the operation of the first radiator connected to the wireless charging assembly, so that the heat dissipation effect of the first radiator has a higher matching degree with the real-time temperature of the mobile device, and significantly improves the heat dissipation effect during wireless charging of the mobile device. In addition, this method does not require a temperature sensor to be installed on the wireless charging assembly, nor does it require a specific placement position for mobile devices such as mobile phones, increasing the flexibility of the wireless charging scenario.

[0060] In some alternative embodiments, the above step S101 includes:

[0061] Step a1: Receive the temperature information sent by the mobile device, where the temperature information is detected by the internal temperature detection element of the mobile device;

[0062] Step a2: Generate a first control signal according to the temperature information.

[0063] Specifically, in the embodiments of the present invention, the wireless charging assembly directly establishes a communication connection with the mobile device. When the wireless charging assembly detects that the mobile device is placed on the charging stand and establishes a communication connection with it, the mobile device will send the temperature information detected inside it to the wireless charging assembly in real time. The wireless charging assembly directly obtains the temperature information of the mobile device and generates a first control signal according to the temperature information according to a predetermined control signal generation strategy, so as to control the operation of the first radiator.

[0064] It should be noted that since there are a very large variety of brands of mobile devices such as mobile phones, and the manufacturing processes of manufacturers of different brands are different, and the wireless charging function is a general function, the standard communication protocol (Qi protocol) for wireless charging between the mobile device and the wireless charging assembly does not support the function of the mobile device sending temperature information to the wireless charging assembly within the current industry standards. Therefore, the ability to implement the above steps a1 to a2 requires the mobile device manufacturer to customize the standard communication protocol (Qi protocol) during the production of the mobile device to make it support sending data of this type of temperature information, ensuring that the temperature information detected by the mobile device can be correctly sent to the wireless charging assembly.

[0065] In some alternative embodiments, the above step S101 further includes:

[0066] Step b1, receiving the temperature information sent by the vehicle-mounted computer, where the temperature information in the vehicle-mounted computer is sent by the mobile device, and the temperature information is detected by the temperature detection element inside the mobile device;

[0067] Step b2, generating a first control signal according to the temperature information.

[0068] Specifically, as Figure 2 shown, in the embodiments of the present invention, the wireless charging assembly and the mobile device establish a communication connection only based on the standard communication protocol (Qi protocol), and the mobile device also establishes a communication connection with the vehicle-mounted computer through a custom private protocol such as Bluetooth and WIFI. When the wireless charging assembly detects that the mobile device is placed on the charging stand and establishes a communication connection with it, the wireless charging assembly only charges the mobile device based on the Qi protocol. And the mobile device sends the temperature information detected inside it to the vehicle-mounted computer in real time, and the vehicle-mounted computer then forwards the temperature information to the wireless charging assembly through the in-vehicle CAN bus, so that the wireless charging assembly obtains the temperature information of the mobile device, and then generates a first control signal according to the temperature information according to a predetermined control signal generation strategy, so as to control the operation of the first radiator.

[0069] Through the above optimization means, manufacturers of mobile devices such as mobile phones do not need to perform customized development on the standard communication protocol (Qi protocol). The wireless charging assembly and the mobile device can still adopt standardized software production, enabling the wireless charging assembly on the vehicle to freely adapt to mobile devices of any brand. Also, since it is easier for the mobile device to communicate with the in-vehicle computer through a private protocol, after establishing a wireless communication connection between the in-vehicle computer and the mobile device, the in-vehicle computer can simply request the temperature information of the mobile device. The solution provided by the embodiments of the present invention not only realizes the transmission function of temperature information, but also reduces the development tasks of customization and personalization. There is no need to consider the custom modification of the Qi protocol, improving the standardization degree of wireless charging heat dissipation, enabling mobile devices of any brand to accurately send temperature information to the wireless charging assembly through the in-vehicle computer after accessing the wireless charging assembly.

[0070] In some alternative embodiments, the above step S101 further includes:

[0071] Step c1, receiving a first control signal sent by the in-vehicle computer, where the first control signal is generated by the in-vehicle computer according to the temperature information, and the temperature information in the in-vehicle computer is sent by the mobile device.

[0072] Specifically, as Figure 3 shown, in the embodiments of the present invention, the wireless charging assembly and the mobile device establish a communication connection only based on the standard communication protocol (Qi protocol), and the mobile device establishes a communication connection with the in-vehicle computer through a private protocol customized through channels such as Bluetooth and WIFI. When the wireless charging assembly detects that the mobile device is placed on the charging base and establishes a communication connection with it, the wireless charging assembly charges the mobile device only based on the Qi protocol. The mobile device sends the temperature information detected inside it to the in-vehicle computer in real time. The in-vehicle computer will generate a first control signal according to the temperature information according to a predetermined control signal generation strategy, and then forward the first control signal to the wireless charging assembly through the CAN bus in the vehicle, so that the wireless charging assembly can directly forward the first control signal to the first radiator.

[0073] Through the above technical means, considering that the processor of the wireless charging assembly often has low performance and low efficiency in executing the radiator control program, it is avoided that the processor with low performance of the wireless charging assembly executes a more complex strategy, and the control strategy is executed by the in-vehicle computer with better performance, improving the control efficiency and balancing the allocation of computing resources in the vehicle.

[0074] Specifically, in some alternative embodiments, the step of generating the first control signal according to the temperature information includes:

[0075] Step d1, determining the temperature range where the temperature information is located based on a plurality of preset temperature thresholds;

[0076] Step d2: If the current temperature range is not the highest temperature range, obtain the target timing period, target control information, and target control coefficient of the current temperature range;

[0077] Step d3: Generate a first control signal output within the current target timing period based on the target control information;

[0078] Step d4: At the end of the current target timing period, re-determine the temperature range where the temperature information is located based on multiple preset temperature thresholds;

[0079] Step d5: If the temperature information is still within the current temperature range and greater than the temperature before the current target timing period, amplify the target control information based on the target control coefficient, and generate a first control signal output within the next target timing period based on the amplified control information;

[0080] Step d6: If the temperature information is still within the current temperature range and less than or equal to the temperature before the current target timing period, use the control signal output within the current target timing period as the first control signal output within the next target timing period.

[0081] Specifically, in the embodiments of the present invention, different temperature ranges are divided by multiple preset temperature thresholds to achieve adaptive control of different heat dissipation effects of the radiator. Among them, each temperature range includes three parameters: a timing period, control information, and a control coefficient. The timing period is the cycle time for outputting the first control signal. Within each timing period, the output first control signal will not change. Whenever a timing period ends, it is necessary to determine whether to adjust the magnitude of the first control signal according to the latest temperature information of the mobile device, so as to control the first radiator through the adjusted first control signal in the next timing period. The control information is the data directly determining the magnitude of the first control signal. For example, assuming the first radiator is a cooling fan, the control information can be a duty cycle signal, and corresponding first control signals are generated through different duty cycle signals to control the rotation speed of the cooling fan. The control coefficient is a proportional coefficient used to adjust the control information. If the heat dissipation effect of the radiator is not good, the control information can be increased through the control coefficient so that the output first control signal increases, thereby improving the heat dissipation effect of the first radiator.

[0082] According to the technical means provided by the embodiments of the present invention, first, it is determined which temperature range the temperature information sent by the mobile device falls into, and then the corresponding target timing period, target control information, and target control coefficient are read. After that, when first entering this range, first generate a corresponding first control signal according to the target control information to control the radiator, and at the same time start timing with the target timing period. When the timing ends, the first cycle ends, and it is determined again based on multiple preset temperature thresholds which temperature range the temperature information is in. If the latest temperature information still falls within the current temperature range, then detect the change trend of the latest temperature information compared with the previous cycle, whether it increases or decreases. If the latest temperature information increases compared with the previous cycle, indicating that the heat dissipation effect is not good, then amplify the target control information based on the target control coefficient, and generate the first control signal output within the next target timing period based on the amplified control information to improve the heat dissipation effect of the radiator, such as increasing the rotation speed of the cooling fan. If the latest temperature information decreases compared with the previous cycle, indicating that the heat dissipation is effective, then do not change the first control signal output within the current target timing period, and directly use it as the first control signal output within the next target timing period to continue controlling the first radiator.

[0083] In some alternative embodiments, after step d4, the following is further included:

[0084] Step d7, if the temperature information is in a higher temperature range and not in the highest temperature range, then generate a first control signal based on the timing period, control information, and control coefficient of the higher temperature range;

[0085] Step d8, if the temperature information is in a lower temperature range, then generate a first control signal based on the timing period, control information, and control coefficient of the lower temperature range.

[0086] Specifically, when a timing cycle ends, it is determined again based on multiple preset temperature thresholds which temperature range the temperature information is in. If the temperature of the mobile device becomes higher and falls into a higher temperature range (not the highest range), the embodiments of the present invention generate a first control signal based on the timing period, control information, and control coefficient of the higher temperature range. If the temperature of the mobile device becomes lower and falls into a lower temperature range, the embodiments of the present invention generate a first control signal based on the timing period, control information, and control coefficient of the lower temperature range. Among them, the strategy for generating the first control signal in the higher temperature range and the lower temperature range is the same as the principle described in steps d1 - d6 above, and will not be elaborated here.

[0087] In some alternative embodiments, the step of generating a first control signal according to the temperature information further includes:

[0088] Step d9, if the current temperature range is the highest temperature range, then stop charging;

[0089] Step d10: Obtain the timing period and control information of the highest temperature range;

[0090] Step d11: Generate a first control signal output within the timing period of the highest temperature range based on the control information of the highest temperature range;

[0091] Step d12: At the end of the current timing period of the highest temperature range, re-determine the temperature range where the temperature information is located based on multiple preset temperature thresholds;

[0092] Step d13: If the temperature information is still within the highest temperature range, repeat the step of generating the first control signal output within the timing period of the highest temperature range based on the control information of the highest temperature range;

[0093] Step d14: If the temperature information is in a lower temperature range, generate a first control signal based on the timing period, control signal, and control coefficient of the lower temperature range.

[0094] Specifically, in the embodiment of the present invention, if the temperature range into which the temperature information falls is not the highest temperature range, the radiator can be controlled based on the strategy described in the above steps d1 to d6. If the temperature range into which the temperature information falls is the highest temperature range, first, charging needs to be stopped to prevent the battery temperature from rising further. Then, a first control signal is generated based on the control information and timing period corresponding to the highest temperature range. Compared with other temperature ranges, the difference is that no control coefficient is set for the highest temperature range, and the control information of the highest temperature range is defaulted to the control signal with the strongest heat dissipation effect and cannot be further increased. Thus, after one timing period, if the temperature information does not drop to a lower temperature range, the step of repeatedly generating the first control signal based on the control information of the highest temperature range is used to control the operation of the radiator.

[0095] According to the above technical means, different temperature ranges are set for different temperatures for control. Among them, the control information corresponding to the temperature range with higher temperature can make the heat dissipation effect stronger. When the temperature falls within a certain range, first, the radiator is started using the predefined target control information in this range. After a timing cycle, the temperature change of the mobile device is judged again. If the temperature range where the temperature information of the mobile device is located has not changed and the temperature has risen slightly, the control signal is enhanced using the target control coefficient to enhance the heat dissipation effect. If the temperature range where the temperature information of the mobile device is located has not changed and the temperature has dropped slightly, the control signal of the previous timing cycle is continued for heat dissipation. Through this solution, an adaptive control method for a radiator is realized, which not only makes the heat dissipation effect more matched with the temperature of the mobile device, but also reduces the energy consumption of the radiator and the cost. If after a timing cycle, the temperature change of the mobile device is judged again, and if the temperature range where the temperature information of the mobile device is located has changed, the same control process is executed again through the control information and control coefficient of the new range, further improving the adaptive control ability of the radiator. In addition, if the temperature of the mobile device reaches the preset highest temperature range, it means that the temperature of the mobile device is too high. At this time, charging should be stopped, and heat dissipation control should be carried out using the timing cycle, control signal, and control coefficient of the high temperature range according to the foregoing strategy to increase the temperature reduction speed of the mobile device.

[0096] According to the adaptive control strategy of the above steps d1 to d10, for the convenience of understanding the solution, in a specific application scenario embodiment, the control strategy of the cooling fan can be described as follows:

[0097] Taking the mobile device with wireless charging as an example of a mobile phone, the strategy of the cooling fan is described below with four temperature ranges as an example. The parameter names of each temperature range are specifically as follows:

[0098] The first temperature range: greater than or equal to the first threshold and less than the second threshold, the first duty cycle, the first timing, and the first coefficient;

[0099] The second temperature range: greater than or equal to the second threshold and less than the third threshold, the second duty cycle, the second timing, and the second coefficient;

[0100] The third temperature range: greater than or equal to the third threshold and less than the fourth threshold, the third duty cycle, the third timing, and the third coefficient;

[0101] The fourth temperature range: greater than or equal to the fourth threshold, the fourth duty cycle, the fourth timing.

[0102] Among them, the duty cycle is used for the initial air volume intensity of the radiator when entering this temperature range. Through the adjustment of the duty cycle, it corresponds to the control information of each temperature range in the foregoing embodiment.

[0103] The first to fourth timings refer to the timing cycles of each temperature range.

[0104] The first to fourth coefficients refer to the control coefficients used to adjust the duty cycle size after the heat dissipation timer overflows.

[0105] As Figure 4 shown, when the temperature of the mobile phone starts to rise slowly, the temperature information of the mobile phone first falls within the first temperature range, and then the fan speed is controlled according to the first duty cycle, and the first timing starts. After the first timing overflows, the latest temperature information of the mobile phone is judged. If the temperature of the mobile phone has risen compared with that before the first timing overflow but has not reached the second threshold, the first duty cycle is increased according to the first coefficient and then the timing starts again, so as to enhance the heat dissipation intensity; if the temperature of the mobile phone rises to the second threshold, it enters the second temperature range for control (in this embodiment, the temperature rises slowly as an example, so the temperature rises from the first temperature range to the second temperature range. In actual application, it may also be that the temperature rises rapidly, and the temperature is directly greater than the third threshold within the first timing time, so it directly enters the third temperature range for control).

[0106] After entering the second temperature range, the initial duty cycle for controlling the fan speed of the heat dissipation fan is the second duty cycle, and the second timing starts. After the second timing overflows, if the temperature of the mobile phone has risen compared with that before the second timing overflow but has not reached the third threshold, the second duty cycle is increased according to the second coefficient and then the timing starts again, so as to enhance the heat dissipation intensity. If the temperature of the mobile phone reaches the third threshold, it enters the third temperature range;

[0107] After entering the third temperature range, the initial duty cycle for controlling the fan speed of the heat dissipation fan is the third duty cycle, and the third timing starts. After the third timing overflows, if the temperature of the mobile phone has risen compared with that before the third timing overflow but has not reached the fourth threshold, the third duty cycle is increased according to the third coefficient and then the timing starts again, so as to enhance the heat dissipation intensity. If the temperature of the mobile phone reaches the fourth threshold, it enters the fourth temperature range;

[0108] After entering the fourth temperature range, first stop charging the wireless charging assembly, and then control the fan speed of the heat dissipation fan to be the fourth duty cycle, and start the fourth timing. After the fourth timing overflows, if the temperature of the mobile phone has not dropped below the fourth threshold, restart the fourth timing and control the fan speed again through the fourth duty cycle.

[0109] As Figure 5 shown, when the temperature of the mobile phone drops slowly, assume that it is first in the fourth temperature range and the fourth timing starts. After the fourth timing overflows, if the temperature of the mobile phone has decreased compared with that before the fourth timing overflow but is still in the fourth temperature range, the fourth duty cycle remains unchanged, and the timing and heat dissipation are restarted; if the temperature of the mobile phone drops below the fourth threshold but is greater than or equal to the third threshold, it enters the third temperature range.

[0110] After entering the third temperature range, the initial duty cycle for controlling the rotational speed of the cooling fan is the third duty cycle, and the third timing starts. If the temperature of the mobile phone decreases compared to before the overflow of the third timing but is still within the third temperature range after the overflow of the third timing, the third duty cycle remains unchanged, and the timing and heat dissipation are restarted. If the temperature of the mobile phone drops below the third threshold but is greater than or equal to the second threshold after the overflow of the third timing, it enters the second temperature range.

[0111] After entering the second temperature range, the initial duty cycle for controlling the rotational speed of the cooling fan is the second duty cycle, and the second timing starts. If the temperature of the mobile phone decreases compared to before the overflow of the second timing but is still within the second temperature range after the overflow of the second timing, the second duty cycle remains unchanged, and the timing and heat dissipation are restarted. If the temperature of the mobile phone drops below the second threshold but is greater than or equal to the first threshold after the overflow of the second timing, it enters the first temperature range.

[0112] After entering the first temperature range, the initial duty cycle is the first duty cycle, and the first timing starts. When the timing overflows, if the temperature of the mobile phone decreases compared to before the overflow of the first timing but is still within the first temperature range, the timing and heat dissipation are restarted. If it is less than the first threshold, the heat dissipation stops.

[0113] In this embodiment, a vehicle-mounted wireless charging heat dissipation method is also provided, which is applied to a vehicle-mounted computer, as Figure 6 shown. The process includes the following steps:

[0114] Step S601, sending a temperature request to the mobile device;

[0115] Step S602, receiving the temperature information fed back by the mobile device in response to the temperature request, where the temperature information is detected by a temperature detection element inside the mobile device;

[0116] Step S603, generating a first control signal based on the temperature information;

[0117] Step S604, sending the first control signal to the wireless charging assembly, so that the wireless charging assembly sends the first control signal to the first radiator to control the first radiator to dissipate heat from the mobile device.

[0120] Step e1, generating a second control signal based on the temperature information;

[0121] Step e2, sending the second control signal to the second radiator to control the second radiator to dissipate heat from the mobile device.

[0122] In some alternative embodiments, a vehicle air-conditioning air outlet is provided near the charging base of the wireless charging assembly, and the second radiator is the vehicle air conditioner.

[0123] Specifically, according to the above technical means, in addition to the radiator directly connected to the wireless charging assembly, an additional independent second radiator can be deployed inside the vehicle, including but not limited to an independent fan, water cooling, etc. The second radiator is directly controlled by the vehicle computer, so that the vehicle computer can generate a second control signal according to the temperature information and control the second radiator to dissipate heat for the mobile device through the second control signal, further expanding the application scenario of the wireless charging heat dissipation solution and improving the heat dissipation capacity. In addition, in an alternative application scenario, the second radiator is the vehicle air conditioner. In the present invention, a vehicle air-conditioning air outlet is provided near the charging base of the wireless charging assembly, and the vehicle computer controls the air outlet of the air conditioner through linkage to dissipate heat for wireless charging, which not only realizes the heat dissipation function, but also reduces the installation of the radiator. The heat dissipation solution can be implemented using the original equipment of the vehicle, reducing the vehicle manufacturing cost.

[0129] Step f5, if the temperature information is still within the current temperature range and greater than the temperature before the current target timing period, amplifying the target control information based on the target control coefficient, and generating the first control signal or the second control signal output within the next target timing period based on the amplified control information;

[0130] Step f6, if the temperature information is still within the current temperature range and less than or equal to the temperature before the current target timing period, using the control signal output within the current target timing period as the first control signal or the second control signal output within the next target timing period.

[0132] Step f8, if the temperature information is in a lower temperature range, generate a first control signal or a second control signal based on the timing period, control information, and control coefficient of the lower temperature range.

[0133] Step f9, if the current temperature range is the highest temperature range, stop charging;

[0134] Step f10, obtain the timing period and control information of the highest temperature range;

[0135] Step f11, generate a first control signal or a second control signal output within the timing period of the highest temperature range based on the control information of the highest temperature range;

[0136] Step f12, at the end of the current timing period of the highest temperature range, re-determine the temperature range where the temperature information is located based on multiple preset temperature thresholds;
