[0036] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0037] With the rapid development of the global economy, the issue of fossil fuel transformation and replacement urgently needs to be addressed, and exploring technologies to solve energy and environmental problems has become one of the most popular research directions in the world today. Electric vehicles (EVs) are characterized by high energy efficiency and low pollutant emissions, possessing significant advantages in energy conservation, emission reduction, and reducing dependence on fossil fuels. However, the current development of EVs is constrained by numerous problems such as inadequate charging infrastructure and charging difficulties. Currently, EVs mainly use wired charging, which suffers from poor charging flexibility, poor user experience, and range anxiety in certain scenarios. To address these issues, Wireless Power Transmission (WPT) technology is currently under development. As EVs are rapidly evolving towards intelligence and connectivity, EVs with autonomous driving and automatic parking capabilities will become the mainstream direction for the future development of new energy vehicles. In this context, leveraging the characteristics and technological advantages of WPT can not only compensate for the shortcomings of wired conductive charging and solve charging problems but also improve the user's charging experience. However, ensuring the efficiency of wireless charging during the wireless charging process remains a critical issue that needs to be addressed.

[0038] The method provided in this application controls whether to wirelessly charge the vehicle when it is in an area supporting wireless charging, based on the vehicle's charging initiation information. Since the charging initiation information reflects the matching degree between the wireless charging receiver and the wireless charging transmitter, it can measure the wireless charging efficiency of the vehicle. Therefore, it ensures that wireless charging is only initiated when the required efficiency is met, thus guaranteeing the vehicle's wireless charging efficiency and avoiding energy waste caused by wireless charging when the efficiency is low.

[0039] Figure 1 This is a schematic diagram of a wireless charging process provided in an exemplary embodiment of this application. Figure 1As shown, when the vehicle 101 is parked within the wireless charging area 102, the vehicle controller of the vehicle 101 acquires the charging start information of the vehicle 101. The vehicle 101 is equipped with a wireless charging receiver, and the wireless charging area 102 is equipped with a wireless charging transmitter. The wireless charging area is a pre-defined area, such as an area pre-defined on a map. In some embodiments, the wireless charging area 102 is a parking space that supports wireless charging. The wireless charging receiver is used to receive charging energy from the wireless charging source, and the wireless charging transmitter is used to transmit charging energy from the wireless charging source. Optionally, the wireless charging receiver is equipped with a receiving coil 103, and the wireless charging transmitter is equipped with a transmitting coil 104. Optionally, the charging start information includes at least one of the following: effective alignment area, vehicle 101 battery information, vehicle 101 external environment information, vehicle 101 parking brake information, and wireless charging switch information. Optionally, the effective alignment area reflects the projected area of ​​the receiving coil 103 in the transmitting coil 104, such as the orthographic projection area. Battery information includes at least one of the following: battery temperature, battery current, battery voltage, and remaining charge of vehicle 101. External environment information includes at least one of the following: ambient temperature, ambient humidity, liveness detection information, and obstacle detection information of the external environment of vehicle 101. Parking brake information reflects the status of the parking brake of vehicle 101. Wireless charging switch information reflects whether the wireless charging function of vehicle 101 is activated.

[0040] Under at least one of the following conditions, the vehicle controller will control the vehicle 101 to receive charging energy from the wireless charging transmitter through the wireless charging receiver, thereby wirelessly charging the vehicle 101: the effective alignment area meets the first wireless charging condition, for example, the effective alignment area is greater than the area threshold; the battery information meets the second wireless charging condition, for example, the remaining power is less than the power threshold; the external environment information meets the third wireless charging condition, for example, there are no living beings or obstacles in the external environment of the vehicle 101; the parking brake information indicates that the parking brake of the vehicle 101 is in the braking state; and the wireless charging switch information indicates that the vehicle 101 activates the wireless charging function.

[0041] By controlling whether to wirelessly charge the vehicle when it is in an area supporting wireless charging, based on the vehicle's charging initiation information, the system can determine whether to wirelessly charge the vehicle. Since the effective alignment area in the charging initiation information can measure the wireless charging efficiency of the vehicle, it can ensure that wireless charging is only initiated when the wireless charging efficiency meets the requirements, thereby guaranteeing the vehicle's wireless charging efficiency and avoiding energy waste caused by wireless charging when the efficiency is low.

[0042] Figure 2This is a schematic flowchart illustrating a wireless charging method provided in an exemplary embodiment of this application. This method can be used in vehicles, such as a vehicle's onboard controller. Figure 2 As shown, the method includes:

[0043] Step 202: Obtain judgment information when the vehicle is parked.

[0044] An on-board controller is a controller integrated into a vehicle for managing vehicle components. In some embodiments, the on-board controller is a controller for managing components related to wireless charging of the vehicle. Optionally, in addition to managing components related to wireless charging, the on-board controller can also be used to manage other components of the vehicle, such as the vehicle's powertrain, safety systems, and comfort systems; this application does not impose limitations on this. In some embodiments, the on-board controller may be referred to as an on-board control module.

[0045] The vehicles described in this application include at least one of the following: unicycles, two-wheeled vehicles, three-wheeled vehicles, four-wheeled vehicles, and vehicles with more than one wheel. The drive system of the vehicles includes at least one of front-wheel drive, rear-wheel drive, and four-wheel drive. The power source of the vehicles includes at least one of gasoline, electricity, hydrogen, and hybrid power. In some embodiments, the vehicles described in this application include, but are not limited to, gasoline-powered vehicles, pure electric vehicles, plug-in hybrid electric vehicles, hybrid electric vehicles, range-extended hybrid electric vehicles, gasoline-powered motorcycles, electric motorcycles, and electric bicycles.

[0046] The vehicle is equipped with a wireless charging receiver, which receives charging energy for wireless charging. Optionally, the wireless charging receiver includes a receiving coil, which receives charging energy based on the principle of electromagnetic induction to achieve the wireless charging process.

[0047] A vehicle being in a parked state refers to a state in which the vehicle remains stationary. Optionally, in a parked state, the vehicle may have its power supply disconnected or maintained; this application does not impose any restrictions on this.

[0048] The determination information is used to determine whether the vehicle's parking location is within a wireless charging area. The wireless charging area is a pre-defined area containing a wireless charging transmitter that emits charging energy. In some embodiments, the wireless charging area is a parking space that supports wireless charging, such as a parking space equipped with a wireless charging transmitter. Optionally, the wireless charging transmitter includes a transmitting coil, which emits charging energy based on the principle of electromagnetic induction to achieve the wireless charging process.

[0049] In some embodiments, the wireless charging area is a pre-defined area on a map. In this case, the determination information includes the location of the wireless charging area on the map and the location of the vehicle's parking position on the map. If the vehicle's location on the map is within the area where the wireless charging area is located, the vehicle controller can determine that the vehicle's parking position is within the wireless charging area.

[0050] In some embodiments, the wireless charging area is a pre-defined area for transmitting a preset signal, which is a pre-set signal transmitted only within the wireless charging area. In this case, the determination information includes the preset signal. When the vehicle is parked, it continuously receives signals transmitted from the outside. When the vehicle controller receives the preset signal, it can determine that the vehicle's parking position is within the wireless charging area.

[0051] It should be noted that the above description of the pre-setting method and judgment information for the wireless charging area is for illustrative purposes only and is not intended to limit the method provided in this application. It is understood that there are other methods besides those described above for setting the pre-setting method and judgment information for the wireless charging area, and this application does not limit these. For example, a camera is installed within the wireless charging area to capture images of the area. If a vehicle is present in the captured image and is parked, the camera will notify the vehicle via wireless equipment that it has entered the wireless charging area.

[0052] Step 204: If the vehicle's parking location is determined to be within the wireless charging area based on the judgment information, obtain the vehicle's charging start information.

[0053] The charging start-up information includes the matching degree between the wireless charging receiver and the wireless charging transmitter. This matching degree is related to the wireless charging efficiency between the wireless charging receiver and the wireless charging transmitter. For example, the matching degree is positively correlated with the wireless charging efficiency between the wireless charging receiver and the wireless charging transmitter.

[0054] In some embodiments, the degree of matching includes the alignment between the wireless charging receiver and the wireless charging transmitter, such as the alignment between the receiving coil in the wireless charging receiver and the transmitting coil in the wireless charging transmitter. A higher degree of alignment results in higher wireless charging efficiency between the wireless charging receiver and the wireless charging transmitter; conversely, a lower degree of alignment results in lower wireless charging efficiency.

[0055] Step 206: If the matching degree meets the first wireless charging condition, control the vehicle to receive charging energy from the wireless charging transmitter through the wireless charging receiver.

[0056] The first wireless charging condition is set based on the degree of matching required to meet wireless charging efficiency. When the matching degree meets the first wireless charging condition, the wireless charging efficiency between the wireless charging receiver and the wireless charging transmitter is greater than an efficiency threshold. Optionally, the first wireless charging condition is set by vehicle technicians. Optionally, wireless charging efficiency is used to measure the proportion of charging energy emitted by the wireless charging transmitter and received by the wireless charging receiver during the wireless charging process.

[0057] Optionally, the alignment degree includes the percentage of alignment between the receiving coil in the wireless charging receiver and the transmitting coil in the wireless charging transmitter. The alignment percentage reflects the proportion of the receiving coil that is aligned with the transmitting coil; this aligned portion is the part of the receiving coil capable of receiving the charging energy emitted by the transmitting coil. When the alignment percentage is greater than a certain threshold, the vehicle controller will control the vehicle to receive charging energy from the wireless charging transmitter through the wireless charging receiver, thereby achieving wireless charging of the vehicle.

[0058] In some embodiments, the vehicle is further equipped with an on-board charger, which is used to charge the vehicle based on the charging energy received by the wireless charging receiver, for example, by converting the charging energy received by the wireless charging receiver into current for charging the vehicle's battery. In some embodiments, the on-board charger may be referred to as an on-board charging module. The vehicle controller establishes an electrical connection with the on-board charger and the wireless charging receiver. During the wireless charging process, the vehicle controller controls the wireless charging receiver to receive charging energy from the wireless charging transmitter and controls the on-board charger to charge the vehicle using the received charging energy, thereby realizing the wireless charging process. Optionally, the wireless charging transmitter may continuously provide wireless charging energy or provide wireless charging energy intermittently. The vehicle controller and the wireless charging transmitter can also establish a communication connection, through which the vehicle controller can control the wireless charging transmitter to provide wireless charging energy. Optionally, through the communication connection, the vehicle controller can also control the amount of wireless charging energy provided by the wireless charging transmitter.

[0059] In summary, the method provided in this embodiment controls whether to wirelessly charge the vehicle based on its charging initiation information when the vehicle is in an area supporting wireless charging. Since the charging initiation information reflects the matching degree between the wireless charging receiver and the wireless charging transmitter, it can measure the wireless charging efficiency of the vehicle. Therefore, it ensures that wireless charging is only initiated when the required efficiency is met, thus guaranteeing the vehicle's wireless charging efficiency and avoiding energy waste caused by charging when the efficiency is low.

[0060] Figure 3 This is a schematic flowchart illustrating a wireless charging method provided in an exemplary embodiment of this application. This method can be used in vehicles, such as a vehicle's onboard controller. Figure 3 As shown, the method includes:

[0061] Step 302: Obtain judgment information when the vehicle is parked.

[0062] An onboard controller is a controller integrated into a vehicle for managing vehicle components. In some embodiments, the onboard controller is a controller for managing components related to wireless charging of the vehicle. Optionally, in addition to managing components related to wireless charging, the onboard controller can also manage other components of the vehicle. The vehicles in this application include at least one of unicycles, two-wheeled vehicles, three-wheeled vehicles, four-wheeled vehicles, and vehicles with more than one wheel. The drive type of the vehicle includes at least one of front-wheel drive, rear-wheel drive, and four-wheel drive. The power source of the vehicle includes at least one of gasoline, electricity, hydrogen, and hybrid power. In some embodiments, the vehicles in this application include, but are not limited to, gasoline-powered vehicles, pure electric vehicles, plug-in hybrid electric vehicles, hybrid electric vehicles, range-extended hybrid electric vehicles, gasoline-powered motorcycles, electric motorcycles, and electric bicycles.

[0063] The vehicle is equipped with a wireless charging receiver, which receives charging energy for wireless charging. Optionally, the wireless charging receiver includes a receiving coil, which receives charging energy based on the principle of electromagnetic induction to achieve the wireless charging process.

[0064] The vehicle being parked refers to the vehicle remaining stationary. Optionally, in the parked state, the vehicle may disconnect its power supply or maintain a power supply; this application does not impose limitations on this. The determination information is used to determine whether the vehicle's parking location is within a wireless charging area. The wireless charging area is a pre-defined area, within which a wireless charging transmitter is installed. The wireless charging transmitter is used to transmit charging energy for wireless charging. In some embodiments, the wireless charging area is a parking space that supports wireless charging, such as a parking space equipped with a wireless charging transmitter. Optionally, the wireless charging transmitter is equipped with a transmitting coil, and the wireless charging transmitter transmits charging energy based on the principle of electromagnetic induction through the transmitting coil to achieve the wireless charging process. In some embodiments, the wireless charging area is a pre-defined area on a map. In some embodiments, the wireless charging area is a pre-defined area for transmitting a preset signal, which is a pre-defined signal transmitted only within the wireless charging area.

[0065] Step 304: If the vehicle's parking location is determined to be within the wireless charging area based on the judgment information, obtain the vehicle's charging start information.

[0066] The charging start-up information includes at least one of the following: the matching degree between the wireless charging receiver and the wireless charging transmitter, the vehicle's battery information, the vehicle's external environment information, the vehicle's parking brake information, and the vehicle's wireless charging switch information. In some embodiments, the on-board controller obtains the above-mentioned charging start-up information through components in the vehicle connected to it.

[0067] The aforementioned matching degree is related to the wireless charging efficiency between the wireless charging receiver and the wireless charging transmitter. In some embodiments, the wireless charging receiver has a receiving coil, and the wireless charging transmitter has a transmitting coil. The matching degree includes the effective alignment area of ​​the receiving coil of the wireless charging receiver. The effective alignment area reflects the projected area of ​​the receiving coil in the transmitting coil. For example, if the wireless charging area is a parking space, the transmitting coil is located on the ground side, and the receiving coil is located at the bottom of the vehicle's battery, the effective alignment area reflects the area occupied by the receiving coil when projected vertically onto the ground within the transmitting coil.

[0068] In some embodiments, the receiving coil has multiple first detection units, and the transmitting coil has multiple second detection units. The effective alignment area is the area occupied by the target detection unit among the multiple first detection units in the receiving coil. The target detection unit is the detection unit among the multiple first detection units that has passed the detection process. The detection process involves the first detection unit sending a detection signal to the second detection unit and receiving a response signal from the second detection unit based on the detection signal. In some embodiments, during the detection process, all first detection units send detection signals, and each of the multiple second detection units sends a corresponding response signal after receiving the detection signal. If a first detection unit receives a feedback signal from any second detection unit, then that first detection unit can be determined as the target detection unit.

[0069] Optionally, the battery information includes at least one of the vehicle's battery temperature, battery current, battery voltage, and remaining charge. In some embodiments, the vehicle's battery includes at least one of a power battery and a non-power battery. The power battery is used to provide electrical power to the vehicle's engine, while the non-power battery is used to provide electrical power to components other than the vehicle's engine, such as at least one of a battery providing power to the air conditioning, a battery providing power to an in-vehicle terminal, or a battery providing power to an emergency call system.

[0070] Optionally, the vehicle's external environment information includes at least one of the following: ambient temperature, ambient humidity, liveness detection information, and obstacle detection information. Liveness detection information reflects the presence of a living being, such as a human or animal, within a preset range outside the vehicle. Obstacle detection information reflects the presence of obstacles, such as pillars, boxes, or cabinets, within a preset range outside the vehicle. In some embodiments, liveness detection information and / or obstacle detection information are detected using cameras, lidar, millimeter-wave radar, or similar devices installed in the vehicle.

[0071] Optionally, the vehicle's parking brake information is used to reflect the state of the vehicle's parking brake, such as whether it is in a braking state or a non-braking state. The parking brake can be understood as a handbrake, electronic handbrake, or parking brake. In some embodiments, when the parking brake is in a braking state, the vehicle's electronic parking brake (EPB) is in a clamped state; when the parking brake is in a non-braking state, the vehicle's EPB is in a released state.

[0072] Optionally, the vehicle's wireless charging switch information is used to indicate whether the vehicle's wireless charging function is activated. In some embodiments, the vehicle's wireless charging switch information is controlled by controls displayed on the vehicle's onboard terminal screen and / or by physical buttons on the vehicle; this application does not impose any limitations on this.

[0073] Step 306: If the charging start information meets the wireless charging conditions, control the vehicle to receive charging energy from the wireless charging transmitter through the wireless charging receiver.

[0074] The effective alignment area in the charging start-up information corresponds to a first wireless charging condition, which includes an area threshold. This area threshold is less than or equal to the area of ​​the receiving coil. Optionally, the first wireless charging condition is set by vehicle technicians. In some embodiments, when the effective alignment area is greater than the area threshold, the vehicle controller controls the vehicle to receive charging energy from the wireless charging transmitter via the wireless charging receiver. When the effective alignment area is the area occupied by the target detection unit among multiple first detection units in the receiving coil, and the occupied area is greater than the area threshold, the vehicle controller controls the vehicle to receive charging energy from the wireless charging transmitter via the wireless charging receiver.

[0075] In some embodiments, when the effective alignment area of ​​the receiving coil is less than or equal to an area threshold, the vehicle controller controls the vehicle to move to the target location. This is achieved when the effective alignment area of ​​the receiving coil at the target location is greater than the area threshold. In some embodiments, the wireless charging area is a parking space, and different parking spaces correspond to preset target locations. These target locations are preset for vehicles of different sizes. For example, a first target location is set for small cars, a second target location for medium-sized cars, and a third target location for large cars. After a vehicle enters a parking space supporting wireless charging, it reports its size information to the server. Based on the target parking space the vehicle has entered, the server determines the first, second, and third target locations corresponding to that parking space. Then, based on the vehicle's size information, the server determines the vehicle's size, thereby identifying the target location corresponding to the vehicle's size from among the first, second, and third target locations, and sending it to the vehicle. In some embodiments, the preset target locations for parking spaces are set by parking space technicians based on the position of the transmitting coil within the parking space, for example, based on the center position of the transmitting coil. In some embodiments, the onboard controller controls the vehicle to move in a random direction. During the movement, it continuously acquires the effective alignment area. If the effective alignment area gradually decreases during movement in the first direction, the vehicle is controlled to return to its starting point in the first direction and move in a second direction different from the first direction. If the effective alignment area gradually increases during movement in the first direction, the vehicle continues to move until the effective alignment area begins to decrease. This process is then repeated until the effective alignment area exceeds an area threshold.

[0076] The vehicle's battery information in the charging start-up information corresponds to a second wireless charging condition. Optionally, the second wireless charging condition includes at least one of a battery temperature threshold, a battery current threshold, a battery voltage threshold, and a remaining charge threshold. Optionally, the second wireless charging condition is set by vehicle technicians. In some embodiments, the on-board controller controls the vehicle to receive charging energy from the wireless charging transmitter through the wireless charging receiver when one or more of the following conditions are met: the vehicle's battery temperature is less than the battery temperature threshold; the vehicle's battery current is less than the battery current threshold; the vehicle's battery voltage is less than the battery voltage threshold; and the vehicle's remaining charge is less than the remaining charge threshold.

[0077] The vehicle's external environment information in the charging start-up information corresponds to a third wireless charging condition. Optionally, the third wireless charging condition includes at least one of an ambient temperature threshold, an ambient humidity range, the absence of living beings in the external environment, and the absence of obstacles in the external environment. Optionally, the third wireless charging condition is set by vehicle technicians. In some embodiments, when one or more of the following conditions are met, the on-board controller will control the vehicle to receive charging energy from the wireless charging transmitter through the wireless charging receiver: the ambient temperature of the external environment is lower than the ambient temperature threshold; the ambient humidity of the external environment is within the ambient humidity range; the liveness detection information reflects that there are no living beings within a preset range outside the vehicle; and the obstacle detection information reflects that there are no obstacles within a preset range outside the vehicle.

[0078] The vehicle's parking brake information in the charging start information corresponds to a fourth wireless charging condition. Optionally, the fourth wireless charging condition includes the vehicle's parking brake being in a braking state. In some embodiments, when the parking brake information indicates that the parking brake is in a braking state, the on-board controller controls the vehicle to receive charging energy from the wireless charging transmitter through the wireless charging receiver.

[0079] The wireless charging switch information for the vehicle in the charging start-up information corresponds to a fifth wireless charging condition. Optionally, the fifth wireless charging condition includes enabling the vehicle's wireless charging function. In some embodiments, when the wireless charging switch information indicates that the vehicle's wireless charging function is enabled, the on-board controller will control the vehicle to receive charging energy from the wireless charging transmitter through the wireless charging receiver.

[0080] In some embodiments, the wireless charging area is a dedicated parking space supporting wireless charging, which belongs to the vehicle owner. An alignment pattern is painted in the dedicated parking space, and a chassis camera facing the ground is installed on the lower surface of the vehicle's chassis. The position of the alignment pattern in the dedicated parking space is determined based on the camera's capture area when the vehicle is parked in the aligned position. When the vehicle is parked in the aligned position, the chassis camera can capture the complete alignment pattern. The alignment position is determined based on the vehicle's parking position in the dedicated parking space when the effective alignment area equals the area of ​​the receiving coil. Optionally, the charging start information also includes an image captured by the chassis camera. If the similarity between the captured image and the alignment pattern is greater than a similarity threshold (e.g., the pattern in the captured image overlaps with the alignment pattern), the vehicle controller will control the vehicle to receive charging energy from the wireless charging transmitter through the wireless charging receiver. A similarity threshold between the captured image and the alignment pattern can indicate that the effective alignment area is greater than an area threshold. It should be noted that the scheme of receiving charging energy from the wireless charging transmitter through the wireless charging receiver based on the captured image can be implemented separately from or in combination with the wireless charging conditions mentioned above, and this application does not impose any restrictions on this.

[0081] In some embodiments, the wireless charging area is a dedicated parking space supporting wireless charging. This dedicated parking space belongs to the vehicle owner and is marked with an alignment pattern. A reversing camera is installed at the rear of the vehicle. The vehicle stores a first image, which is the image captured by the reversing camera in the alignment pattern when the vehicle is parked in the aligned position. The alignment position is the vehicle's parking position in the dedicated parking space when the effective alignment area equals the area of ​​the receiving coil. Optionally, the process of parking the vehicle in the alignment position to obtain the first image is controlled by the vehicle's driver. Optionally, after obtaining the first image, when the vehicle controller determines that the vehicle is parked in the dedicated parking space, the reversing camera will capture a second image. If the second image captured by the reversing camera is inconsistent with the first image, the vehicle controller will guide the vehicle to move in the direction of travel until the second image captured by the reversing camera is completely consistent with the first image. Optionally, during the process of guiding the vehicle's movement, the on-board controller acquires a first reference image corresponding to the alignment pattern in the first captured image and a second reference image corresponding to the alignment pattern in the second captured image, and analyzes the distortion of the second reference image compared to the first reference image. Based on the distortion and the vehicle's current position, the on-board controller determines the alignment position within the designated parking space, thereby determining the vehicle's direction of travel from its current position to the alignment position. After determining the direction of travel, the on-board controller guides the vehicle to move in that direction, ensuring that the vehicle is parked in the alignment position, thus guaranteeing that the effective alignment area equals the area of ​​the receiving coil.

[0082] It should be noted that the wireless charging conditions provided in this embodiment can be implemented separately. For example, meeting any one of the wireless charging conditions can trigger the vehicle to receive charging energy from the wireless charging transmitter via the wireless charging receiver. The wireless charging conditions can also be implemented in combination. For example, meeting two or more of the wireless charging conditions will trigger the vehicle to receive charging energy from the wireless charging transmitter via the wireless charging receiver. For example, if the matching degree meets the first wireless charging condition and the battery information meets the second wireless charging condition, the vehicle will receive charging energy from the wireless charging transmitter via the wireless charging receiver. Another example is if the matching degree meets the first wireless charging condition and the external environment information meets the third wireless charging condition, the vehicle will receive charging energy from the wireless charging transmitter via the wireless charging receiver. Yet another example is if the matching degree meets the first wireless charging condition and the parking brake information indicates that the parking brake is in a braking state, the vehicle will receive charging energy from the wireless charging transmitter via the wireless charging receiver. In some embodiments, if one or more of the wireless charging conditions are not met during the wireless charging process, the wireless charging process will stop. Additionally, the wireless charging process will stop if the vehicle leaves the wireless charging area.

[0083] In some embodiments, the vehicle is further equipped with an on-board charger, which is used to charge the vehicle based on the charging energy received by the wireless charging receiver, for example, by converting the charging energy received by the wireless charging receiver into current for charging the vehicle's battery. The on-board controller establishes an electrical connection with the on-board charger and the wireless charging receiver. During wireless charging, the on-board controller controls the wireless charging receiver to receive charging energy from the wireless charging transmitter and controls the on-board charger to charge the vehicle using the received charging energy, thereby realizing the wireless charging process. Optionally, the wireless charging transmitter may continuously provide wireless charging energy or provide it intermittently. The on-board controller and the wireless charging transmitter can also establish a communication connection, through which the on-board controller can control the wireless charging transmitter to provide wireless charging energy. Optionally, through the communication connection, the on-board controller can also control the amount of wireless charging energy provided by the wireless charging transmitter.

[0084] Wireless charging of the vehicle can be achieved by controlling the vehicle's onboard controller to receive charging energy from the wireless charging transmitter via the wireless charging receiver. In some embodiments, the vehicle's battery includes a power battery and a non-power battery. The power battery provides power to the vehicle's engine, while the non-power battery provides power to components other than the engine, such as at least one of the following: a battery providing power to the air conditioner, a battery providing power to the vehicle's onboard terminal, or a battery providing power to an emergency call system. When wireless charging is triggered, the vehicle's power battery and / or non-power battery can be charged. In some embodiments, the onboard controller obtains a first predicted power consumption of the power battery over a preset future time period and a second predicted power consumption of the non-power battery over the same preset time period. Optionally, the first predicted power consumption is determined based on the power battery's power consumption over a historical period, and the second predicted power consumption is determined based on the non-power battery's power consumption over a historical period. If the first predicted power consumption is greater than the remaining power of the power battery, the vehicle controller will control the charging of the power battery; if the second predicted power consumption is greater than the remaining power of the non-power battery, the vehicle controller will control the charging of the non-power battery; if the first predicted power consumption is greater than the remaining power of the power battery and the second predicted power consumption is greater than the remaining power of the non-power battery, the vehicle controller will control the charging of both the power battery and the non-power battery simultaneously.

[0085] In summary, the method provided in this embodiment controls whether to wirelessly charge the vehicle based on its charging initiation information when the vehicle is in an area supporting wireless charging. Since the charging initiation information reflects the matching degree between the wireless charging receiver and the wireless charging transmitter, it can measure the wireless charging efficiency of the vehicle. Therefore, it ensures that wireless charging is only initiated when the required efficiency is met, thus guaranteeing the vehicle's wireless charging efficiency and avoiding energy waste caused by charging when the efficiency is low.

[0086] The method provided in this embodiment further ensures accurate wireless charging efficiency by determining whether to wirelessly charge the vehicle based on whether the effective alignment area is greater than an area threshold. It also ensures the safety of the wireless charging process by determining whether to wirelessly charge the vehicle based on its battery information, its external environment information, and its parking brake information, ensuring wireless charging occurs when the vehicle is parked and braked.

[0087] It should be noted that this application may display prompt interfaces, pop-ups, or output voice prompts before and during the collection of user-related data (such as external environmental information in this application). These prompt interfaces, pop-ups, or voice prompts are used to inform the user that their relevant data is being collected. This ensures that the application only begins the steps related to collecting user-related data after receiving confirmation from the user regarding the prompt interface or pop-up; otherwise (i.e., without receiving confirmation from the user), the steps to collect user-related data end, meaning no user-related data is collected. In other words, all user data collected in this application is collected with the user's consent and authorization, and the collection, use, and processing of relevant user data must comply with the relevant laws, regulations, and standards of the relevant countries and regions.

[0088] It should be noted that the order of the method steps provided in the embodiments of this application can be appropriately adjusted, and the steps can also be added or removed as appropriate. Any method variations that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the protection scope of this application, and therefore will not be elaborated further.

[0089] In some embodiments, the method provided in this application is applied to a wireless charging system, which includes a wireless charging transmitter, a wireless charging receiver, an on-board controller, and an on-board charger. The wireless charging receiver, on-board controller, and on-board charger are installed in a vehicle and connected wirelessly or via a wired connection. In some embodiments, the wireless charging transmitter and the on-board controller have a communication connection. In some embodiments, the wireless charging transmitter may be referred to as a Ground Assembly (GA), the wireless charging receiver as a Vehicle Assembly (VA), the on-board controller as an On-board Control Module, and the on-board charger as an On-board Charging Module.

[0090] The vehicle controller is used to acquire judgment information when the vehicle is parked. This judgment information determines whether the vehicle's parking position is within a wireless charging area, which is a pre-defined area containing a wireless charging transmitter. The vehicle controller also acquires charging initiation information when the judgment information confirms the vehicle is within the wireless charging area. This charging initiation information includes the matching degree between the wireless charging receiver and the wireless charging transmitter, which is related to the wireless charging efficiency between them. Furthermore, if the matching degree meets a first wireless charging condition, the vehicle controller controls the wireless charging receiver to receive charging energy from the wireless charging transmitter and controls the vehicle charger to charge the vehicle using this energy.

[0091] For example, Figure 4 This is a schematic diagram of a wireless charging system provided in an exemplary embodiment of this application. Figure 4 As shown: In some embodiments, the wireless charging transmitter is located on the ground side and connected to the single-phase power grid 401. The wireless charging transmitter includes a rectifier and filter circuit, a high-frequency inverter circuit, a signal control circuit, a primary-side compensation circuit, and a transmitting coil. For example... Figure 4 The diagram shows a rectifier bridge 402, a multiphase interleaved power factor corrector (PFC) 403, a multiphase interleaved buck converter 404, a full-bridge inverter 405, a primary-side LCC compensation network 406, a primary-side controller 407, and a transmitting coil 408. The wireless charging transmitter's function is to rectify the AC power from the grid side into DC power, and then convert it into high-frequency AC power through a high-frequency inverter circuit. This high-frequency AC power can generate a changing magnetic field through the primary-side coil, using the alternating magnetic field to transmit electrical energy to the vehicle (wireless charging receiver). In some embodiments, the wireless charging receiver is located in the lower housing of the vehicle's power battery and includes a receiving coil, a rectifier circuit, a power regulation circuit, a signal control circuit, and the vehicle's power battery. For example... Figure 4 The receiver coil 409, secondary-side controller 410, secondary-side LCC compensation network 411, open-circuit protection circuit 412, rectification and filtering circuit 413, and battery pack 414 are shown. For example, Figure 5 This is a schematic diagram of a receiving coil and a transmitting coil provided in an exemplary embodiment of this application. Figure 5As shown, the wireless charging receiver captures the alternating magnetic field generated by the wireless charging transmitter through the receiving coil 409. Based on the principle of electromagnetic induction, an induced electromotive force is generated in the receiving coil 409, which is then rectified and filtered to charge the vehicle's power battery. In some embodiments, the vehicle control module is used to control the signal interaction between the wireless charging transmitter (primary-side controller 407), the wireless charging receiver (secondary-side controller 410), and the vehicle charging module. For example, it controls the wireless communication unit between the wireless charging transmitter and the wireless charging receiver, and the Controller Area Network (CAN) network between the various vehicle modules to recharge the vehicle's power battery system. In some embodiments, the vehicle charging module receives the high-frequency AC power output from the wireless charging receiver, and after rectification, power regulation, compensation network, and filtering circuitry, outputs high-voltage DC power matching the power battery to recharge it.

[0092] In some embodiments, the on-board control module acquires vehicle charging start-up information (e.g., external environmental information and the operating status of the vehicle's internal wireless charging system), and, when the charging start-up information meets the wireless charging conditions, sends charging control commands to the wireless charging transmitter, wireless charging receiver, and on-board charging module to wirelessly charge the vehicle. In some embodiments, the on-board control module controls the operating status of the wireless charging transmitter, wireless charging receiver, and on-board charging module through charging control commands, thereby controlling their operating status based on information related to the operating environment of the wireless charging system when the charging start-up information meets the wireless charging conditions. In some embodiments, the on-board control module includes a wireless transmitter controller, a wireless receiver controller, and a charging controller that interacts with the vehicle. It accurately locates and matches the transmitting coil of the wireless charging transmitter and the receiving coil of the wireless charging receiver, and dynamically interacts with the vehicle's high-voltage charging system to control the on-board wireless charging system to charge the vehicle's power battery.

[0093] In some embodiments, during the process of the vehicle control module controlling the vehicle to wirelessly charge, it acquires the "AutoParking" signal from the vehicle's intelligent driving system (integrating functions such as automatic parking, memory parking, and autonomous valet parking) to determine whether the vehicle's parking position is within the wireless charging area and whether the coils of the wireless charging transmitter and receiver are effectively coupled (effective alignment area). For example, when the "AutoParking_OK" signal is received, indicating that the vehicle's parking position is within the wireless charging area, a charging enable command "Enable-Wireless_Charging" is sent to the wireless charging transmitter, wireless charging receiver, and vehicle charging module. During this process, the vehicle control module also dynamically collects and monitors the vehicle's charging status (charging start information) in real time through the vehicle's built-in vision, LiDAR, voltage, and current sensors, realizing two-way intelligent interaction between the vehicle wireless charging system and the vehicle, and providing reasonable and effective charging control and fault diagnosis data for the wireless charging system.

[0094] For example, Figure 6 This is a schematic diagram of a wireless charging process provided in an exemplary embodiment of this application. (In conjunction with...) Figure 6 The following describes the wireless charging process for vehicles:

[0095] (1) When the remaining charge (State of Charge, SoC) of the vehicle's power battery is less than 10%, or when the local / network wireless charging enable signal "Enable-Wireless_Charging" flag is "1", the wireless charging system will start to confirm the alignment information (whether the effective alignment area is greater than the area threshold) through the detection unit. If the alignment status flag is "0" (alignment invalid), "Location-Match_Fail" will be reported to the vehicle control module, and the vehicle control module will issue a stop wireless charging command to stop the execution of wireless charging action.

[0096] (2) When the SoC of the vehicle's power battery is below 10%, or when the local / network wireless charging enable signal "Enable-Wireless_Charging" flag is "1", the wireless charging system will start to confirm the alignment information through the position detection unit. If the alignment status flag is "1" (alignment is valid), "Location-Match_OK" will be reported to the vehicle control module. The vehicle control module will issue a wireless charging command, and the vehicle charging module will perform the wireless charging action.

[0097] (2-1) When the effective alignment area of ​​the wireless charging transmitter and the wireless charging receiver 601 meets the area threshold A, and the wireless charging soft switch of the in-vehicle display (In-Vehicle Infotainment Unit (IHU) 602) meets state B (on), and the EPB 603 meets state C (clamped), wireless charging will be triggered. The vehicle control module will send a wireless charging wake-up signal "Wireless_Charging_Wakup" to the wireless charging transmitter, wireless charging receiver 601, voltage control unit (VCU) 604, battery management system (BMS) 605 and other controllers, and simultaneously report the "Start_Wireless_Charging" status to VCU 604. After receiving the signal, VCU 604 sends a "Wireless_Charging_Request" command to BMS 605. After BMS 605 passes the self-test, it simultaneously performs pre-charging and closes the high-voltage relay, and the vehicle enters the normal wireless charging process.

[0098] (2-2) When the effective alignment area of ​​the wireless charging transmitter and the wireless charging receiver 601 meets the area threshold A, or the wireless charging soft switch of the vehicle display meets state B' (closed) and the EPB 603 meets state C' (released), the wireless charging system will maintain real-time monitoring and report the "Wireless_Charging_Monitor" status to the VCU 604. After receiving the status, the VCU 604 sends the "Wireless_Charging_RequestPause" command to the BMS 605. After completing the self-test, the BMS 605 enters the waiting state and reports the "Charging_Waiting" status to the VCU 604. When the wireless charging system meets the wireless charging conditions, the vehicle re-enters the normal wireless charging process according to the charging strategy described in (2-1).

[0099] (3) During the wireless charging process in (2-1), if any one or more of the following conditions are not met: effective alignment area between the wireless charging transmitter and receiver 601, wireless charging soft switch on the vehicle display screen, or EPB status, the vehicle control module will immediately stop sending the wireless charging wake-up signal "Wireless_Charging_Wakup" and stop waking up the controllers such as the wireless charging transmitter, receiver 601, VCU 604, and BMS 605. The wireless charging system will enter the "Wireless_Charging_Standby" state. If the above fault conditions are restored to normal within 20 minutes (inclusive), the wireless charging fault counter will be cleared, and the flag bit will be "0". At this time, the wireless charging system can recover automatically and send the wireless charging wake-up signal "Wireless_Charging_Wakup" again to the controllers such as the wireless charging transmitter, receiver 601, VCU 604, and BMS 605. At the same time, the "Start_Wireless_Charging" status will be reported to the VCU. After receiving the status, VCU 604 sends a "Wireless_Charging_Request" command to BMS 605. BMS 605 simultaneously performs self-test, pre-charge, and closes the high-voltage relay, allowing the vehicle to re-enter the normal wireless charging process. If the above fault condition lasts for more than 20 minutes, the wireless charging fault counter (Wireless_Charging fault-Counter) continues counting with its flag set to "1". The wireless charging system enters a sleep state, no longer monitoring whether the wireless charging condition has recovered. Simultaneously, the system exits the wireless charging state, switching the local / network wireless charging enable signal "Enable_Wireless_Charging" to "Disable_Wireless_Charging". Afterwards, when the vehicle again uses the local / network wireless charging enable signal "Enable_Wireless_Charging" with its flag set to "1", or after a power cycle, the wireless charging system can again execute the charging processes corresponding to (2-1) and (2-2). Additionally, regarding the interaction process of other modules in the wireless charging system, for example... Figure 6The interaction processes between the Temperature Management Module (TMM) 606 and the water pump 607, the interaction processes between the Charge Module & DC-DC Converter (CMDC) 608 and the VCU 604, and the interaction processes between the Central Electronic Module (CEM) and the VCU 604 can be found in the following diagrams. Figure 6 As shown.

[0100] In conclusion, this application can effectively alleviate the range anxiety problem of new energy electric vehicles, especially when there is sufficient solar irradiance and duration and no charging equipment is available to recharge the vehicle's power battery. It can significantly increase the driving range of new energy electric vehicles, improve the user's driving experience, and has extremely high market application value.

[0107] In an optional design, the control module 702 is used to control the vehicle to move to a target position when the effective alignment area is less than or equal to the area threshold; wherein the effective alignment area corresponding to the receiving coil when the vehicle moves to the target position is greater than the area threshold.
