Furthermore, uneven road surfaces, speed bumps, and off-road driving can cause vehicle vibrations, leading to electronic devices bouncing or colliding with the charging panel, resulting in interrupted wireless charging or damage to the phone.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0049] This application embodiment adds an electromagnetic positioning ring to the charging plane of the vehicle-mounted wireless charging device, thereby achieving positioning, anti-slip, and fixation of electronic devices during wireless charging. This reduces problems such as misalignment of the electronic device with the charging coil of the wireless charging device, and phone bumps and charging interruptions caused by road bumps. To better understand the vehicle-mounted wireless charging control method of this application embodiment, the application scenario of the control method is first described.

[0050] Figure 1 This is a schematic diagram of the structure of a wireless charging device provided in an embodiment of this application. Figure 1 As shown, the wireless charging device 100 can be installed inside a vehicle and includes a charging panel 110, a charging coil 120, and an electromagnetic positioning ring 130. The charging coil 120 and the electromagnetic positioning ring 130 are disposed on the charging panel 110, and the electromagnetic positioning ring 130 and the charging coil 120 are installed together.

[0051] Figure 2 This is a schematic diagram of the structure of an electronic device 200 requiring wireless charging, as provided in an embodiment of this application. Figure 2 As shown, taking a mobile phone as an example, the electronic device 200 may include a wireless charging induction coil 210 and a magnet 220 disposed on the surface of the electronic device. The magnet 220 may be integrated into the mobile phone along with the wireless charging induction coil 210, or it may be externally disposed on the surface of the electronic device.

[0052] based on Figure 1The wireless charging device 100 shown in the vehicle and Figure 2 The electronic device 200 shown, Figure 3 A schematic diagram illustrating the principle of wireless charging in an embodiment of this application is provided. For example... Figure 3 As shown, when the vehicle's wireless charging device 100 is working, the charging coil 120 converts electrical energy into magnetic energy, and the wireless charging induction coil 210 of the electronic device 200 converts magnetic energy into electrical energy, thereby realizing the wireless transmission of electrical energy.

[0053] Compared to related technologies for in-vehicle wireless charging of electronic device 200, this embodiment adds an electromagnetic positioning ring 130 to the wireless charging device 100. Since magnets 220 are provided on the surface of electronic device 200, the electromagnetic positioning ring 130 can determine the position of electronic device 200 through electromagnetic interaction with it. For example, by changing the magnetic field strength of the electromagnetic positioning ring 130, functions such as positioning, anti-slip, and fixation of electronic device 200 can be achieved. This improves the stability of wireless charging of electronic device 200 under various driving conditions in the vehicle.

[0054] Additionally, this embodiment may include a vehicle road recognition device 300, which can be positioned in front of the vehicle to identify the road conditions on which the vehicle is located. The vehicle road recognition device 300 can communicate with the wireless charging device 100, sending the collected road information to the wireless charging device 100. The wireless charging device 100 then analyzes the received road information to determine the road conditions on which the vehicle is located. The vehicle road recognition device 300 can be an in-vehicle image acquisition device, such as an in-vehicle 360-degree video surveillance system; this embodiment does not limit this to a specific type.

[0055] Please see Figure 4 , Figure 4 This is a schematic diagram of a vehicle-mounted wireless charging control system provided in an embodiment of this application. The control system may include the wireless charging device 100 described above.

[0056] The wireless charging device 100 may include a charging panel 110, a charging coil 120, and an electromagnetic positioning ring 130. The electromagnetic positioning ring 130 includes a controller 131, a magnetic coil 132, and a magnetic core 133. The controller 131 is connected to the magnetic coil 132 and controls the current in the magnetic coil 132. The magnetic coil 132 is arranged around the magnetic core 133.

[0057] Please see Figure 5 , Figure 5This is a schematic diagram of a controller 131 provided in an embodiment of this application. The controller 131 is connected to a magnetic coil 132 and is used to adjust the current in the magnetic coil 132. Due to the interaction between the magnetic field generated by the current passing through the wire and the magnetic core 133, the magnetic coil 132 and the magnetic core 133 can adjust the magnetic attraction force according to the current magnitude. The magnetic core 133 creates a closed magnetic path within the magnetic field. When current passes through the magnetic coil 132, a magnetic field is generated around the current according to Ampere's law. This magnetic field passes through the magnetic core 133, forming a strong magnetic field.

[0058] Figure 6 This is a schematic diagram of the structure of a magnetic core 133 provided in an embodiment of this application. Figure 6 As shown, the material of the magnetic core 133 can be nickel-zinc ferrite, manganese-zinc ferrite, or other iron oxide mixtures suitable for making magnetic cores and with fast demagnetization. It can be composed of multiple arc-shaped magnetic core units, forming an overall circular shape. The magnetic core units are evenly arranged, with the number of units ranging from 8 to 36. A set of these units is wound around each magnetic core unit in a manner where the axis is perpendicular to the vehicle charging panel 110, and the north-south direction of the magnetic poles of all magnetic core units is consistent. As an example, polyimide film, polytetrafluoroethylene, or other insulating materials can be used as the insulating layer, and copper or aluminum, or other materials with good conductivity, can be used as the wires.

[0059] Since the magnetic core 133 is made of a material with high magnetic permeability, this strong magnetic field interacts with the magnetic material of the core to generate a magnetic attraction force. The magnitude of the magnetic attraction force changes according to the magnetic field strength, which is proportional to the magnitude of the current. Therefore, in this embodiment, the controller 131 can control the operating current of the magnetic coil 132 based on an electrical signal, such as a current signal, to adjust the magnetic field strength formed by the interaction between the magnetic core 133 and the magnetic coil 132. Then, the operating mode of the electromagnetic positioning coil 130 is determined based on the magnetic field strength.

[0060] The electromagnetic positioning ring 130 exerts different magnetic attraction forces on electronic devices in different operating modes. Specifically, the stronger the magnetic field, the stronger the magnetic attraction force. Conversely, the weaker the magnetic field, the weaker the magnetic attraction force. For example, the electromagnetic positioning ring 130 can include a positioning mode, an anti-slip mode, and a fixed mode. The positioning mode positions the electronic device with only a small magnetic force. The anti-slip mode prevents the electronic device from sliding, requiring a strong magnetic force, and is typically suitable for smooth surfaces. The fixed mode uses a larger magnetic force to fix the electronic device to the charging panel 110, and is typically suitable for bumpy surfaces. Therefore, the magnetic field strength in the positioning mode is less than that in the anti-slip mode, and vice versa.

[0061] Based on the above-described vehicle-mounted wireless charging control system, the control method for vehicle-mounted wireless charging according to the embodiments of this application will be described in detail below. Figure 7 This is a flowchart illustrating a control method for in-vehicle wireless charging provided in an embodiment of this application. Figure 7 As shown, the control method may include steps 701-702, which will be described in detail below.

[0062] Step 701: Determine the control parameters of the vehicle's wireless charging device based on the vehicle's driving status.

[0063] Step 702: Control the working state of the wireless charging device according to the control parameters.

[0064] In this embodiment, the vehicle's driving state refers to its current state, which may include, but is not limited to, the vehicle's current driving state and the road conditions of the road on which the vehicle is currently traveling. Since the wireless charging device in this embodiment also includes an electromagnetic positioning ring, it can perform adsorption operations on electronic devices with different magnetic field strengths. Therefore, based on different driving states, the control parameters of the vehicle's wireless charging device can be determined. These control parameters refer to the parameters by which the wireless charging device performs the adsorption operation on the electronic device. As an example, the control parameters of the wireless charging device can be electrical signals. Based on these electrical signals, the adsorption force of the electromagnetic positioning ring on the electronic device can be determined, thereby determining the working state of the wireless charging device. The working state of the wireless charging device refers to the adsorption force of the wireless charging device on the electronic device. Specifically, the wireless charging device generates an adsorption force on the electronic device through the electromagnetic positioning ring. Therefore, the working state of the wireless charging device corresponds to the working mode of the electromagnetic positioning ring. The working modes of the electromagnetic positioning ring include, but are not limited to, the aforementioned positioning mode, anti-slip mode, and fixed mode.

[0065] In summary, this application embodiment determines the control parameters of the vehicle's wireless charging device based on the vehicle's driving status to control the device's operating state. Since the vehicle's wireless charging device has magnetic attraction, it can support electronic devices. Therefore, by controlling the operating state of the wireless charging device based on the road conditions and the vehicle's own driving status, electronic devices requiring wireless charging can be stably placed on the device, improving the stability of in-vehicle wireless charging.

[0066] In this embodiment, the wireless charging device may include an electromagnetic positioning coil, and the control parameters may include the electrical signal of the electromagnetic positioning coil. Therefore, in step 702, the electrical signal value of the electromagnetic positioning coil can be determined according to the vehicle's driving status. As an example, the electrical signal may include the operating current of the magnetic coil.

[0067] In this embodiment, the driving state can include the vehicle's current driving state and the road condition of the road the vehicle is currently traveling on. The driving state can include the vehicle being in motion or parked. The driving state can be determined based on the vehicle's speed sensor. When the vehicle's speed sensor reading is less than a set value, for example, when the vehicle's current speed is 0, the vehicle can be determined to be parked. The road condition of the road the vehicle is currently traveling on can be determined based on information sent by the vehicle's road recognition device. For example, it can be determined whether the road is currently bumpy based on images detected by the vehicle's road recognition device, LiDAR, or radar detection signals. Similarly, it can also be determined based on the vehicle's sensor information. For example, the travel of the suspension springs can be obtained based on the suspension displacement sensor. Whether the road is bumpy can be compared based on a set threshold. If it is greater than the set threshold, the road can be determined to be bumpy; if it is less than or equal to the set threshold, the road can be determined to be smooth. For example, if the suspension spring travel is greater than a set travel, the current road is bumpy. Conversely, if the suspension spring travel is less than or equal to the set travel, the current road is smooth. As an example, the vehicle status data in this embodiment can all be acquired based on sensors that communicate with the controller. Examples of determining electrical signal values ​​based on different vehicle states are given below.

[0068] Taking the driving state as an example, in step 702, when the vehicle's driving state is detected to be parked, the electrical signal value is determined as the first electrical signal value. The first electrical signal value is an electrical signal value that can be used to adjust the potential of the wirelessly charged electronic device. In the parked state, the electronic device can perform wireless charging based on a smaller electrical signal value.

[0069] Taking road conditions as an example, in step 702, when the road condition is detected to be smooth, the electrical signal value is determined as the second electrical signal value. This second electrical signal value is designed to prevent the wirelessly charged electronic device from slipping. The second electrical signal value is greater than the first electrical signal value, meaning it is a medium-sized electrical signal value. At this second electrical signal value, the electronic device can maintain charging stability by reducing the possibility of slippage, and it also reduces the likelihood of the electronic device sliding on the wireless charging device due to vehicle movement, thus improving the efficiency of wireless charging.

[0070] When a bumpy road condition is detected, the electrical signal value is determined as the third electrical signal value. This third electrical signal value is one that can hold the wirelessly charging electronic device in place. The third electrical signal value is greater than the second electrical signal value; that is, the third electrical signal value is larger. At this third electrical signal value, the wireless charging device can hold the wirelessly charging electronic device in place, thereby reducing the impact and bounce of the electronic device caused by road bumps, thus addressing the stability and safety considerations of wireless charging.

[0071] It should be noted that the specific implementation of the control electrical signal value based on driving status described above is only an example. The vehicle-mounted wireless charging control system based on the embodiments of this application can also determine the electrical signal for the controller to control the magnetic coil based on various vehicle driving states, thereby changing the adhesion of the wireless charging device to electronic devices and improving the stability of wireless charging of electronic devices under various driving states.
