The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

As shown in fig. 1, a schematic structural diagram of an embodiment of a charging control system provided in the present application may include a plurality of transmitting coils 101 disposed in a vehicle, a control module 102, a detection module 103 connected to the control module 102, and a power supply module 104 connected to the plurality of transmitting coils 101 and the control module 102, respectively.

The detection module 103 may detect first position information of the receiving coil in the terminal device, and send a first detection result to the control module 102;

the control module 102 may determine a target transmitting coil whose distance from the receiving coil meets a preset condition from among the plurality of transmitting coils 101 based on the first detection result of the detection module 103, and control the power supply module 104 to supply power to the target transmitting coil;

the target transmit coil may transfer power to the receive coil to charge the terminal device.

In this embodiment, the charging control system may be applied to a vehicle, and may charge a terminal device in the vehicle, such as a wearable device, where the wearable device may be, for example, a smart watch, an electronic wristband, or the like. Wherein the terminal device may be provided with a receiving coil therein, and the vehicle interior may be provided with a plurality of transmitting coils. The transmitting coil may be provided at a steering wheel, door panel, etc. in the vehicle interior, and there are various implementations, which will be described in the following embodiments. The number of the transmitting coils may be set to 3, 5, 10, etc., without limitation.

The transmitting coil may transmit electrical energy to the receiving coil by means of magnetic resonance to charge the terminal device. When the magnetic resonance technology is used for charging, the resonance frequency of 6.87Mhz can be adopted, so that the interference to other electronic equipment and the radiation injury to human bodies are avoided. The charging process is not described in detail.

When charging using magnetic resonance techniques, the charging efficiency is typically related to the frequency, the structure of the transmit and receive coils, and the distance between the transmit and receive coils. In this embodiment of the present application, the frequency and the coil structure are generally fixed, and in this case, in order to improve the charging efficiency, a transmitting coil whose distance from the receiving coil meets a preset condition may be selected from a plurality of transmitting coils, and may be referred to as a target transmitting coil, so as to perform charging.

In this embodiment, the charging control system may include a detection module, which may detect position information of the receiving coil, and may be referred to as first position information. The detection module may be implemented as a locator component, may directly determine the location information of the receiving coil, may also be implemented as a sensor component, may determine the location information of the receiving coil based on an acquired image containing the terminal device, based on image analysis, etc.

The charging control system also comprises a control module connected with the detection module. The control module may be implemented as a microprocessor, which may be integrated in a controller of the vehicle. The detection module may send a first detection result including the first position information to the control module, so that the control module may learn the first position information of the receiving coil.

Optionally, the control module may further acquire location information of each of the plurality of transmitting coils, so as to perform distance calculation with the receiving coil.

As an alternative implementation, the transmitting coils may be arranged at fixed positions in the vehicle, such as preset positions on the door panel, etc., at which time the control module may obtain the position information of each transmitting coil. As an alternative implementation, the position of the transmitting coil may also be changed, e.g. provided on the steering wheel, turned along with the steering wheel, etc., in which case the position information of the transmitting coil may also be detected and obtained, as will be described in the following embodiments.

After the control module obtains the first position information of the receiving coil, the distances between the receiving coil and the plurality of transmitting coils can be calculated respectively, and the transmitting coil corresponding to the distance meeting the preset condition is determined and used as the target transmitting coil.

As an alternative implementation, the preset condition may be that the distance is minimum. At this time, the control module may select a transmitting coil corresponding to the minimum distance therefrom as the target transmitting coil. As another alternative implementation, the preset condition may also be that the distance is smaller than the preset distance. At this time, the control module may use the transmitting coil corresponding to a distance less than the preset distance as the target transmitting coil. The preset distance may be, for example, 5cm, 7cm, etc., without limitation. Alternatively, the distance between the plurality of transmitting coils and the receiving coil may be smaller than a preset distance, and at this time, the control module may use any transmitting coil as the target transmitting coil.

After the target transmitting coil is determined, the control module may control charging of the receiving coil with the target transmitting coil. Specifically, the charging control system further comprises a power supply module respectively connected with the control module and the plurality of transmitting coils. The power supply module can be realized as a power supply assembly or a power management assembly, and is connected with the power supply module of the vehicle to convert the electric energy provided by the power supply module into the electric energy provided for the transmitting coil, so that the power supply module is not limited. The control module can control the power supply module to supply electric energy to the target transmitting coil so that the target transmitting coil can transmit the electric energy to the receiving coil in a magnetic resonance mode to wirelessly charge the terminal equipment.

In this embodiment, the charging control system may include a plurality of transmitting coils disposed in a vehicle, a control module, a detection module connected with the control module, and a power supply module connected with the plurality of transmitting coils and the control module, where the detection module may detect first position information of a receiving coil in the terminal device, and the control module may determine, from the plurality of transmitting coils disposed in the vehicle, a target transmitting coil whose distance from the receiving coil meets a preset condition based on the detected first position information, so as to control the power supply module to supply electric energy to the target transmitting coil, and transmit the electric energy to the receiving coil by using the target transmitting coil, and charge the terminal device. Through utilizing the inside target transmitting coil of arranging of vehicle to transmit the electric energy to receiving coil, realize carrying out wireless charging to terminal device, need not to utilize the wire to connect the power and charge, simplified the operation that charges, improved the convenience of charging, and target transmitting coil is based on the receiving coil's that detects the position information that obtains, and the determined transmitting coil that accords with the preset condition with receiving coil's distance, has improved wireless charging efficiency.

The following describes the manner in which the transmitting coil is disposed in the vehicle interior. The plurality of transmitting coils may be sleeved on a grip portion of a steering wheel in the vehicle and/or on at least one door panel of the vehicle.

As an alternative implementation, a plurality of transmitting coils may be sleeved on different positions of the grip portion of the steering wheel. The distance between different transmitting coils may be the same or different, and is not limited.

Alternatively, the plurality of transmitting coils may be vertically sleeved on the grip portion of the steering wheel.

Optionally, the plurality of transmitting coils may be sleeved on the holding portion of the steering wheel according to respective preset inclination angles. As shown in fig. 2a, a schematic diagram of one embodiment of the transmitting coil disposed on the steering wheel is shown. The transmitting coils A1, A2 and A3 are respectively sleeved on different positions of the steering wheel holding part, and the inclination angles are different, namely, the axial directions of the transmitting coils are different, so that the multi-position and multi-angle setting is realized, and the setting flexibility of the transmitting coils is improved.

As another alternative implementation, a plurality of transmit coils may be disposed on at least one door panel. Taking four doors in a vehicle as an example, the transmitting coils can be arranged on at least one of the main frame door plate, the auxiliary driving door plate, the left rear door plate and the right rear door plate, and the number of the transmitting coils on one door plate can be set according to actual needs without limitation.

Alternatively, the plane of at least one transmitting coil provided on the same door panel may be identical to the plane of the door panel. As shown in fig. 2b, a schematic view of one embodiment of the door panel is provided for the transmitting coil. The transmitting coils B1, B2 and B3 are respectively arranged on the main frame door plate, the plane where the transmitting coils are positioned is consistent with the plane where the main frame door plate is positioned, namely, the axes of the transmitting coils are oriented the same and are perpendicular to the plane where the main frame door plate is positioned, so that the multi-position arrangement is realized.

As a further alternative implementation mode, a plurality of transmitting coils can be sleeved on the holding part of the steering wheel and arranged on at least one door plate, the inclination angles of the transmitting coils sleeved on the holding part of the steering wheel can be different, the plane of the transmitting coils on the same door plate can be consistent with the plane of the door plate, the multi-position multi-angle setting is realized, and the setting flexibility of the transmitting coils is further improved.

In practical applications, the position of the transmitting coil sleeved on the holding part of the steering wheel of the vehicle will change along with the movement of the steering wheel. At this time, the detection module may further detect third position information corresponding to each of the plurality of transmitting coils, and send the second detection result to the control module. The control module may determine, from the plurality of transmitting coils, a target transmitting coil whose distance from the receiving coil meets a preset condition based on the first detection result and the second detection result of the detection module.

Alternatively, the first position information may include a center point position of the receiving coil, and the third position information may include a plane position and an axis position where the transmitting coil is located.

The control module may determine, for any one of the transmit coils, a first sub-distance between a center point position of the receive coil and a plane position of the transmit coil, and a second sub-distance between the center point position of the receive coil and an axis of the transmit coil, and determine a distance between the transmit coil and the receive coil based on the first sub-distance and the second sub-distance.

Fig. 2c shows a schematic diagram of an embodiment of determining the distance of a transmitting coil from a receiving coil. As shown in fig. 2c, the transmitting coils A1, A2 and A3 are respectively sleeved on the holding part of the steering wheel according to respective preset inclination angles, and the receiving coil O is located in a terminal device (not shown in the figure).

The first position information detected and obtained by the detection module may include a center point position of the receiving coil O, and the third position information may include positions of the planes (not shown) and axes l1, l2, and l3 where the transmitting coils A1, A2, and A3 are located, respectively.

For the transmitting coil A1, the control module may determine a first sub-distance d1 between the center point position of the receiving coil O and the plane position of the transmitting coil A1, and a second sub-distance d2 between the center point position of the receiving coil O and the axis l1 of the transmitting coil A1.

The control module may then determine a distance between the transmit coil A1 and the receive coil O based on the first sub-distance d1 and the second sub-distance d 2. For example, the first sub-distance d1 and the second sub-distance d2 may be added, and the sum may be used as the distance between the transmitting coil A1 and the receiving coil O. For another example, the first sub-distance d1 and the second sub-distance d2 may be weighted to obtain the distance between the transmitting coil A1 and the receiving coil O. The weight coefficient m corresponding to the first sub-distance, the second sub-distance d2 and the corresponding weight coefficient n can be set according to the actual scene. By setting the weight coefficient, the accuracy of the distance between the transmitting coil and the receiving coil can be improved.

For the transmitting coil A2 and the transmitting coil A3, the control module may determine a first sub-distance between the center point position of the receiving coil O and the plane position of the transmitting coil A2, determine a second sub-distance between the center point position of the receiving coil O and the axis l2 of the transmitting coil A2, determine a distance between the transmitting coil A2 and the receiving coil O based on the first sub-distance and the second sub-distance, and determine a second sub-distance between the center point position of the receiving coil O and the axis l2 of the transmitting coil A3 based on the first sub-distance and the second sub-distance, which are not repeated.

Then, the control module can determine a transmitting coil corresponding to the distance meeting the preset condition as a target transmitting coil.

For a plurality of transmitting coils sleeved on the steering wheel holding part according to respective preset inclination angles, the distance between the transmitting coils and the receiving coils is determined together based on the sub-distance relation between the central point of the receiving coils and the plane where each transmitting coil is located and the sub-distance relation between the central point of the receiving coils and the axes of each transmitting coil, so that the distance determination accuracy is improved.

In the above manner of determining the distance between the transmitting coil and the receiving coil, each transmitting coil is sleeved on the holding part of the steering wheel, and at this time, the planes of the transmitting coils are inconsistent and the axial directions are different, so that the relationship between the sub-distance of the central point of the receiving coil to the plane of the transmitting coil and the relationship between the central point of the receiving coil to the axis of the transmitting coil are determined together. In practical application, when the transmitting coils are arranged on the door panels, the planes of the transmitting coils on the same door panel are consistent with the plane of the door panel, and the axial directions are perpendicular to the plane of the door panel, namely the axial lines are parallel to each other. At this time, the distance between the transmitting coil and the receiving coil may also be determined in different manners.

In practice, the position of the transmitting coil provided on the door panel is usually fixed. At this time, the control module may directly obtain fourth position information corresponding to each of the plurality of transmitting coils, and determine, from the plurality of transmitting coils, a target transmitting coil whose distance from the receiving coil meets a preset condition based on the first detection result and the fourth position information of the detection module.

Alternatively, the fourth location information may include a center point location of each of the transmitting coils.

The control module may determine, for any one of the transmit coils, a distance of a center point position of the receive coil from a center point position of the transmit coil as a distance of the transmit coil from the receive coil.

Fig. 2d shows a schematic diagram of another embodiment of determining the distance of a transmitting coil from a receiving coil. As shown in fig. 2d, the transmitting coils B1, B2 and B3 are disposed on the same door panel, the planes of the transmitting coils B1, B2 and B3 are all identical to the plane of the door panel, the axes are all perpendicular to the plane of the door panel, and the receiving coil O is located in a terminal device (not shown).

The first position information detected and obtained by the detection module may include a center point position of the receiving coil O, and the fourth position information may include respective center point positions of the transmitting coils B1, B2, and B3.

For the transmitting coil B1, the control module may determine a distance D1 of the center point position of the receiving coil O from the center point position of the transmitting coil B1 as a distance of the transmitting coil B1 from the receiving coil O. For the transmitting coil B2, the control module may determine a distance D2 of the center point position of the receiving coil O from the center point position of the transmitting coil B2 as a distance of the transmitting coil B2 from the receiving coil O, and for the transmitting coil B3, the control module may determine a distance D3 of the center point position of the receiving coil O from the center point position of the transmitting coil B3 as a distance of the transmitting coil B3 from the receiving coil O.

Then, the control module can determine a transmitting coil corresponding to the distance meeting the preset condition as a target transmitting coil.

For a plurality of transmitting coils arranged on the same door plate, the distance between the center points of the transmitting coils and the receiving coils is directly determined, and the distance is used as the distance between the transmitting coils and the receiving coils, so that the distance determination process is simplified, and the processing efficiency is improved.

In practical application, in order to further improve the charging efficiency of the transmitting coil, the target transmitting coil can be controlled to rotate after being determined. As shown in fig. 3, which is a schematic structural diagram of another embodiment of the charging control system, the system may further include a driving module 105 connected to the plurality of transmitting coils and the control module 102, respectively.

Wherein the control module may be further configured to drive the target transmitting coil to rotate within a preset rotation angle range through the driving module 105 based on the second position information between the target transmitting coil and the receiving coil.

In this embodiment, the inside of the door panel and/or the inside of the grip portion of the steering wheel may be provided with a cavity for placing the transmitting coil and the driving module, the transmitting coil and the driving module may be provided inside the cavity, and the transmitting coil may be rotatable inside the cavity. The transmitting coil arranged in the inner cavity of the door plate rotates to enable an included angle to be formed between the plane where the transmitting coil is located and the plane where the door plate is located, and the transmitting coil arranged in the inner cavity of the holding part of the steering wheel rotates to enable the axis direction of the transmitting coil to be changed. The rotation angle range of the transmitting coil may be set in advance. The driving module may be implemented as a universal connector, etc., without limitation.

The control module may control rotation of the target transmit coil based on second position information between the target transmit coil and the receive coil. The second position information may include information of a connecting line between the center of the target transmitting coil and the center of the receiving coil, specifically, the control module may use a connecting line between the center of the target transmitting coil and the center of the receiving coil, and an included angle between axes of the target transmitting coil is minimum as a rotating target, and control the target transmitting coil to rotate within a preset rotation angle range through the driving module, so that an axis direction of the target transmitting coil approaches to a direction of the central connecting line to the greatest extent, and charging efficiency is improved.

In practical application, when a plurality of transmitting coils are sleeved on the holding part of the steering wheel, the detection module can comprise a first detector and a second detector. As shown in the schematic diagrams of fig. 3 or 4, the first detector 1031 and the second detector 1032 may be respectively connected to the control module 102.

The first detector may be for detecting a center point position of a receiving coil in the terminal device;

the second detector may be configured to detect a planar position and an axis position of the plurality of transmit coils, respectively.

There are a number of implementations of the first detector.

As an alternative implementation, the first detector may comprise an ultra wideband UWB positioning module, which may detect the location of the center point of the receiving coil in the terminal device.

As another alternative implementation, the first detector may include a camera sensor, where the camera sensor may collect an image of the vehicle, and the image may include a terminal device, and obtain a center point position of a receiving coil in the terminal device based on image analysis.

The second detector may also have a variety of implementations.

As an optional implementation manner, the second detector may also include a camera sensor, where the camera sensor may collect an image in the vehicle, and the image may include a steering wheel, and obtain, based on image analysis, a position of a sleeved area corresponding to the transmitting coil in a grip portion of the steering wheel, and further determine, based on a preset inclination angle of the transmitting coil, a plane position and an axis position corresponding to the transmitting coil at the position.

As another alternative implementation manner, the second detector may include a steering wheel angle positioning module, where the steering wheel angle positioning module may detect steering wheel angle information corresponding to the plurality of transmitting coils, and the steering wheel angle information may be used to determine a plane position and an axis position where the transmitting coils are located.

Fig. 2e shows a schematic view of an embodiment of a steering wheel angle. As shown in fig. 2e, the current position of the transmitting coil (which may include the corresponding current center point position, the current plane position, the current axis position, etc.) may be determined based on the initial position (which may include the initial center point position, the initial plane position, the initial axis position, etc.) of the transmitting coil set on the steering wheel and the steering wheel angle a, which is not described in detail.

In an actual driving scene, taking an example that the terminal device is an intelligent watch worn by a driving user, the position of a receiving coil in the intelligent watch can be changed at any time in the process that the driving user controls a steering wheel, and at the moment, the distance between the receiving coil and each transmitting coil can be changed no matter the transmitting coil is arranged on a door plate or the steering wheel. Therefore, the detection module can detect the first position information of the receiving coil and/or the third position information of the transmitting coil in real time, and the control module can determine and change the target transmitting coil in real time and control the power supply module to supply power to the target transmitting coil.

Of course, to avoid frequent determination and modification of the target transmit coil, in some embodiments, the charge control system may also include a timer;

the control module may be further configured to determine a target transmit coil from the plurality of transmit coils having a distance from the receive coil that meets a preset condition for a preset time set by the timer. The preset time may be, for example, 350ms, 500ms, etc., without limitation.

By setting the interval time, the occupation of data processing resources is reduced while the charging efficiency is ensured, and the reasonable setting of the charging efficiency and the data processing resources is realized.

Optionally, the detection module may also detect the first position information of the receiving coil and/or the third position information of the transmitting coil at intervals of a preset time set by the timer, and send a detection result to the control module, so as to reduce detection resource occupation.

As shown in fig. 4, which is a schematic structural diagram of another embodiment of the charging control system, the system further includes a display module 106 connected to the control module 102, and the detection module includes a third detector 1033 in addition to the first detector 1031 and the second detector 1032, and the third detector 1033 may be connected to the plurality of transmitting coils 101.

Wherein the third detector 1033 may be configured to detect an operating state of the target transmitting coil and send a third detection result to the control module 102;

the control module 102 may also be configured to determine the operational information of the target transmit coil based on the third detection result of the third detector 1033, and control the display module 106 to display the operational information of the target transmit coil.

The operating state of the target transmit coil may include, for example, output power, operating time duration, operating failure, etc. The third detector may detect it and send a third detection result to the control module. The third detector may be implemented as a detection circuit or the like without limitation.

The control module can determine the operation information corresponding to the target transmitting coil, such as output power value, operation duration information, fault information and the like, and control the display module to display, so that a user can clearly determine the charging condition.

The display module may be implemented as a display screen, display interface, etc., and may be integrated into a display component of the vehicle, such as an instrument panel, etc. The display module can display the operation information in different modes such as characters, patterns, colors and the like, and is not limited.

Optionally, the display module may further include a trigger control, such as a switch button, a virtual key, such as a determination key, a return key, etc., to support user interaction, so as to control the charging process. For example, in response to a user's trigger operation of the off button, a control signal to stop charging may be generated, so that the control module may control the power supply module to stop supplying power to the target transmitting coil.

Optionally, the third detector 1033 may also be used to detect obstacle information between the target transmitting coil and the receiving coil, and send a fourth detection result to the control module 102.

The control module 102 may be further configured to re-determine a target transmitting coil having a distance from the receiving coil that meets a preset condition from the remaining plurality of transmitting coils in the case where an obstacle exists between the target transmitting coil and the receiving coil based on the fourth detection result of the third detector 1033, and control the power supply module 104 to supply power to the re-determined target transmitting coil.

The obstacle information may include a conductor such as a metal, and the third detector may be implemented as a metal detector, etc., without limitation.

The control module may determine whether an obstacle exists between the target transmitting coil and the receiving coil based on the fourth detection result, e.g., if the fourth detection result is empty, it is determined that no obstacle exists, etc. And under the condition that the existence of the obstacle is judged, the target transmitting coil is redetermined, and the power supply module is controlled to supply power to the redetermined target transmitting coil, so that the influence on the power transmission with the receiving coil caused by the overhigh temperature of the system is avoided.

As shown in fig. 5, a schematic structural diagram of another embodiment of the charging control system further includes a communication module 107 connected to the control module 102.

The communication module 106 may establish a connection with the terminal device, and send the power demand information of the receiving coil in the terminal device to the control module 102;

the control module 102 may also be configured to control operation of the power module 104 based on the power demand information.
