[0040] For the convenience of understanding the embodiments of the present application, the embodiments of the present application will be explained first in detail in terms of the technical background and possible application scenarios:

[0041] With the continuous progress of electric vehicle technology, in-vehicle wireless charging function has been gradually applied and popularized in automobiles. From luxury models to entry-level models, most of them are equipped with this function. Wireless charging not only improves the convenience, aesthetics, efficiency and safety of in-vehicle charging. When driving out, there is no need to carry various charging cables, which can effectively avoid the messy situation of too many cables in the vehicle. At the same time, it also enhances the user experience. Moreover, the wireless charging module is usually designed exquisitely and beautifully, which can be used as a decorative element in the vehicle, improving the overall grade of the car.

[0042] At present, most in-vehicle wireless charging devices (hereinafter referred to as wireless charging devices) on the market are usually fixedly installed in parts such as the center console, the central storage box, and the armrest box. Users only need to place the mobile phone in the designated charging area to achieve wireless charging. However, this kind of wireless charging method is mostly fixed. The mobile phone (or other devices to be charged, such as smart watches, etc.) can be charged when placed in the charging area, and the charging stops when the mobile phone leaves the charging area. There is a lack of interaction with the driver, and the user experience is insufficient. The charging panels of most wireless charging devices are placed horizontally. In the case of vehicle turning, sudden acceleration or sudden deceleration, the mobile phone is likely to fall off the charging panel to the ground, which will distract the user's attention during driving and increase the driving risk. In addition, the current wireless charging function also lacks a function of reminding the user to take the mobile phone. When the user leaves the vehicle, the mobile phone may be left on the charging panel and the user forgets to take his own mobile phone, resulting in the user may miss important message notifications on the mobile phone, thus affecting the user experience.

[0043] In view of this, the embodiments of the present application provide a control method, device and electronic device for an in-vehicle wireless charging device, aiming to implement an intelligent control strategy for the in-vehicle wireless charging lifting mechanism. By adding a lifting mechanism to the wireless charging module and controlling the lifting mechanism to run corresponding strategies, the user experience of the wireless charging system is improved. The following further introduces the embodiments of the present application in combination with the application scenarios:

[0044] The technical solution provided by the embodiments of this application can be applied to the application scenario of intelligent driving. Exemplarily, the execution subject of the control method of the in-vehicle wireless charging device provided by the embodiments of this application can be a vehicle. Specifically, it can be the controller of the vehicle. This controller can be a Body Domain Controller (BDC), or other domain controllers, such as the Cockpit Domain Controller (CDC) of an intelligent vehicle, etc. In addition, it can also be an electronic control unit (ECU), an in-vehicle terminal, etc.; in some examples, the execution subject of the control method of the in-vehicle wireless charging device provided by the embodiments of this application can also be a server, such as a cloud server, a distributed server, etc. This embodiment does not particularly limit the specific execution subject of the above method, and only takes the BDC domain controller as an example for illustration.

[0045] Optionally, Figure 1 A possible system framework is shown, including an in-vehicle wireless charging device. This in-vehicle wireless charging device includes a Wireless Charging Module (WLCM) and an Electric Lift Machine (ELM). Among them, the WLCM can be used to detect the placement and removal of the mobile phone and realize automatic charging of the mobile phone. The ELM can realize the automatic lifting function of the WLCM. It also includes a BDC electrically connected to the in-vehicle wireless charging device. The BDC communicates with the WLCM through a Bluetooth Low Energy (BLE) module to respond to whether the WLCM detects the mobile phone. Among them, the BLE is connected to the WLCM through a Controller Area Network (CAN) line and connected to the BDC through BSCAN to realize communication between the BDC and the WLCM. And the BDC is connected to the ELM through a Local Interconnect Network (LIN) line to control the automatic lifting function of the ELM.

[0046] In this scenario, the BDC's control method for the lifting function of the ELM can calibrate the position of the ELM, enabling the lifting mechanism to be in the first calibration position in the initial state and in the second calibration position during the charging state. When the wireless charging panel detects a mobile phone, the BDC controls the lifting mechanism to descend from the first calibration position to the second calibration position, so that the wireless charging panel is placed in the accommodating cavity corresponding to the second calibration position to charge the mobile phone. Compared with the related art, where only the lifting function of the wireless charging panel is controlled, when there is a position deviation in the wireless charging panel (such as deviations caused by factors like structural shaking on complex roads or deviations due to long-term use, etc.), the wireless charging panel cannot descend to the corresponding position, resulting in the problem of the mobile phone falling off not being effectively solved. However, in the embodiments of the present application, by calibrating the position of the lifting mechanism and charging the mobile phone based on the calibrated structure, the above technical problems are effectively solved, improving driving safety. In addition, the BDC can also set functions such as anti-play protection, fault detection, and forgetting reminders to further improve the performance of in-vehicle wireless charging and enhance the user's interaction experience.

[0047] Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein.

[0048] Figure 2 The flowchart of the control method of the in-vehicle wireless charging device provided by the embodiments of the present application is shown. The in-vehicle wireless charging device includes a wireless charging panel and a lifting mechanism connected to the wireless charging panel. This method is executed by the BDC controller. As Figure 2 shown, this method may include steps S101 and S102.

[0049] Optionally, the number of the wireless charging panel and the lifting mechanism of the in-vehicle wireless charging device in this embodiment is not particularly limited. For example, Figure 3 the in-vehicle wireless charging device shown, Figure 3 the state of the in-vehicle wireless charging device may be that the lifting mechanism is in the initial state (corresponding to the first calibration position, when not charging). It may include two wireless charging panels ① and ②. ① is the wireless charging panel for the driver's seat, and ② is the wireless charging panel for the passenger seat. These two wireless charging panels can be respectively connected to corresponding lifting mechanisms (not shown). The BDC can control these two lifting mechanisms respectively. When a device to be charged (such as a mobile phone) is detected, it controls the lifting mechanism to descend into the accommodating cavity to prevent the mobile phone from falling off during driving. The specific control process Figure 2 is shown as:

[0050] Step S201: Calibrate the position of the lifting mechanism so that the lifting mechanism is in the first calibration position in the initial state and in the second calibration position in the charging state.

[0051] In this embodiment, the first calibration position and the second calibration position are respectively outside and inside the accommodation cavity. Among them, the first calibration position can be the virtual upper limit position 0x0stopin upperarea of the defined lifting mechanism, which is outside the accommodation cavity and can be flush with or slightly higher than the accommodation cavity; the second calibration position can be the virtual lower limit position 0X2stop in lowerarea of the defined lifting mechanism, which is inside the accommodation cavity. Optionally, as Figure 4 shown, the first calibration position and the second calibration position are at the corresponding virtual upper limit position (Upper area) and virtual lower limit position (Lower area), where the virtual upper limit position corresponds to the top dead center position (the highest position of the lifting mechanism), and the virtual lower limit position corresponds to the bottom dead center position (0 point, the lowest position of the lifting mechanism).

[0052] It should be noted that the first calibration position and the second calibration position can be adaptively determined in combination with the actual application. For example, the second calibration position can be adaptively determined in combination with the thickness of the device to be charged, so that the device to be charged sinks into the accommodation cavity in the charging state without exceeding the accommodation cavity.

[0053] Step S202: In response to the wireless charging panel detecting the device to be charged, control the lifting mechanism to descend from the first calibration position to the second calibration position, so that the wireless charging panel is placed in the accommodation cavity corresponding to the second calibration position to charge the device to be charged.

[0054] In this embodiment, by adding a lifting mechanism to the wireless charging device, when the wireless charging panel detects a device to be charged such as a metal mobile phone, the BDC controls the wireless charging panel to automatically descend to a certain position, reaching the virtual lower limit position 0X2stop in lowerarea, so that the wireless charging panel charges the wireless charging panel in the accommodation cavity. Optionally, the wireless charging panel can use an induction coil to detect the device to be charged. When the device to be charged is placed on the charging panel, the induction coil will generate an electromagnetic field, thereby detecting whether there is a device to be charged.

[0055] Through the above technical solution, compared with the related art, merely by controlling the lifting function of the wireless charging panel, when there is a position deviation in the wireless charging panel (such as the deviation caused by factors such as the structure shaking on complex roads or the deviation caused by long-term use, etc.), the wireless charging panel cannot descend to the corresponding position, resulting in the problem that the anti-drop function of the mobile phone cannot be effectively solved. The lifting control method after position calibration in this embodiment can effectively solve the problem that the anti-drop function of the device to be charged fails due to the inability of the wireless charging panel to descend to the corresponding position when there is a position deviation in the wireless charging panel, effectively improving driving safety.

[0056] In this embodiment, considering that the reason for the deviation generated by the lifting mechanism mainly comes from the large number of uses, the position calibration of the lifting mechanism is realized by obtaining the number of movements of the lifting mechanism to reduce the number of position calibration times. For example Figure 5 As shown, the method provided in this embodiment may further include step S501, and step S201 is further divided into step S201a.

[0057] Step S501: Obtain the number of movements of the lifting mechanism.

[0058] Optionally, each time the lifting mechanism moves, it can be recorded in the BDC, such as in the Electrically Erasable Programmable Read-Only Memory (EEPROM) of the BDC.

[0059] Step S201a: When the number of movements reaches the first preset number, perform position calibration on the lifting mechanism.

[0060] It should be noted that those skilled in the art can adaptively determine the first preset number in combination with actual applications. For example, it can be set to 4000 times. When the recorded number of movements of the lifting mechanism reaches 50 times, perform position calibration on the lifting mechanism.

[0061] In some embodiments, in addition to performing the position calibration function on the lifting mechanism in combination with the number of movements of the lifting mechanism, position calibration can also be performed under other conditions. For example, by obtaining the current road condition information, when the road slope is large or the vehicle is driving in other non-stable road conditions and the user has a charging requirement, perform position calibration on the lifting mechanism.

[0062] Through the above technical solution, while ensuring that the wireless charging device is not affected by position deviation, unnecessary position calibration processes can be reduced, and the wireless charging efficiency can be improved.

[0063] In some embodiments, to further improve the position calibration efficiency, the method may further include the following steps: calibrating the first calibration position and the second calibration position as the stop state positions; calibrating the positions other than the first calibration position and the second calibration position as the motion state positions; the above step S301 of obtaining the number of movements of the lifting mechanism may be implemented in the following manner: obtaining the number of movements of the elevator according to the recording result of the change of the lifting mechanism from the stop state position to the motion state position.

[0064] Optionally, taking the initial state of the lifting mechanism as the virtual upper limit position 0x0 stop in upper area as an example, when the position state of the wireless charging lifting mechanism changes from (0x0 stop in upper area or 0X2 stop in lower area) to (0x1 normal moving or 0x3 init moving) (i.e., from stop to non-stop), the BDC records that the movement count is incremented by 1 and stores this count in the BDC EEPROM. When the accumulated number of times is greater than 400 times (it can be other values), by sending an "initialization instruction" to the lifting mechanism, the ELM is made to perform a position calibration action to ensure that there is not too much deviation in the position of the ELM during continuous up and down movements.

[0065] Through the above technical solution, by calibrating the stop state position and the motion state position, the number of movements of the lifting mechanism can be quickly identified, thereby improving the efficiency of position calibration.

[0066] Figure 6 It is a schematic flowchart of another control method of the in-vehicle wireless charging device provided by the embodiments of the present application. On the basis of the above implementation, in this embodiment, after the BDC controls the lifting mechanism to descend to charge the device to be charged, when the device to be charged is removed, it automatically rises to the corresponding calibration position for the user's next charging, and by locking the lifting mechanism under certain conditions, the anti-play protection function of the wireless charging device is realized, thereby reducing the loss of the lifting mechanism. Specifically, in addition to the above steps S101 and S102, this embodiment further includes steps S601 and S602 after the above step S102.

[0067] Step S601: In response to the wireless charging panel not detecting the device to be charged, control the lifting mechanism to rise from the second calibration position to the first calibration position.

[0068] In this embodiment, when the wireless charging panel does not detect the device to be charged, the BDC automatically raises the lifting mechanism to the first calibration position through control, which does not affect the normal use functions of the positions where the wireless charging device is installed (such as the center console, the central storage box, etc.), and is convenient for the user's next charging.

[0069] Step S602: When the number of times of switching between detecting the device to be charged and not detecting the device to be charged by the wireless charging panel reaches a second preset number within a preset time period, and the lifting mechanism is currently at the second calibration position, lock the lifting mechanism.

[0070] Based on the above automatic lifting function, when the placement position of the device to be charged (such as a mobile phone) is not appropriate enough (such as placed at the edge of the wireless charging panel), it may cause the wireless charging panel to jump back and forth between detecting the mobile phone and not detecting the mobile phone. In order to prevent the mobile phone from not being placed in the middle position of the wireless charging panel, resulting in the wireless charging panel continuously detecting the presence and absence of the mobile phone, the lifting mechanism will continuously perform descending and ascending actions back and forth. Such continuous actions are likely to damage the motor and lifting function of the wireless charging lifting mechanism (such as being prone to jamming), and at the same time affect the user experience. In this embodiment, by monitoring that the number of times of switching between detecting the device to be charged and not detecting the device to be charged reaches the second preset number, and when the lifting mechanism is at the virtual lower limit position, the lifting mechanism is locked, so as to achieve anti-play protection during the wireless charging process, thereby reducing the loss of the lifting mechanism and improving the user experience at the same time.

[0071] It should be noted that those skilled in the art can adaptively set the second preset number and the preset time period according to the actual application. For example, the second preset number can be set to 50 times.

[0072] Further, on the basis of the above anti-play protection (i.e., thermal protection), in order to improve the system's discrimination between user operations and the deviation of the mobile phone placement, a counting function is added. When the BDC is in the ON gear, it can monitor that the lifting mechanism (such as the motor of the lifting mechanism) moves every 0.7 seconds (0x1 normal moving or 0x3 init moving), and the thermal protection counter is incremented by 2. When it stops moving every 0.7 seconds (0x0 stop in upper area or 0X2 stop in lower area), the counter is decremented by 1. When it is detected that the wireless charging lifting mechanism is stationary for more than 6 seconds, the count is cleared. If the counter exceeds 50 (the minimum value of the counter is 0) and the wireless charging lifting mechanism is in the descending position, the BDC no longer sends a movement lifting instruction to the ELM, and enters the anti-play protection to prevent the wireless charging lifting mechanism from lifting and lowering back and forth. During this process, the counting function and the count clearing function are added, which can improve the system's discrimination of the user's intentional operations and the deviation of the placement position of the mobile phone.

[0073] In some embodiments, after the lifting mechanism is locked, in order not to affect the normal use of the user, it is automatically unlocked in the following manner. Specifically, after the lifting mechanism is locked in the above steps, the following steps may further be included: when it is first determined that there is no device to be charged on the wireless charging panel, the locking of the lifting mechanism is released, and the lifting function of the lifting mechanism is restored; or, when the power is reset, the locking of the lifting mechanism is released, and the lifting function of the lifting mechanism is restored.

[0074] In this embodiment, when it is first determined that there is no device to be charged (no mobile phone) on the wireless charging panel, it may be that when the wireless charging panel has not detected a mobile phone for a certain period of time (such as 15 s, or other set time), the BDC determines based on the fact that the wireless charging panel has not detected a mobile phone within 15 s, indicating that the user has taken the mobile phone from the wireless charging panel and ended the charging behavior this time. By touching here to lock, the lifting mechanism restores the automatic lifting function.

[0075] In this embodiment, the power reset may be the state where the BDC power is switched to the OFF gear. When the method provided in this embodiment is applied to other devices, it corresponds to the reset of the power supply of that device, or it may also be the power reset of the wireless charging device, or the vehicle power reset, etc.

[0076] Optionally, for the above unlocking function, after the anti-play protection is triggered for only 1 second and the bracket is in the lowered position, when the wireless charging panel detects that there is a mobile phone once and then becomes without a mobile phone, or the BDC is switched to the power OFF gear, the normal lifting of the ELM can be restored.

[0077] In addition to the above unlocking methods, in some embodiments, other methods may also be used for unlocking. For example, by receiving a user instruction, it is unlocked passively based on the user instruction (such as when the user sends an unlocking instruction to the BDC, the BDC releases the locking of the lifting mechanism based on the unlocking instruction), and so on.

[0078] Through the above technical solution, after the lifting mechanism enters the anti-play protection state, the lifting function of the lifting mechanism can be quickly restored.

[0079] Figure 7 It is a schematic flowchart of another control method for an in-vehicle wireless charging device provided by an embodiment of the present application. On the basis of the above embodiments, considering that when the lifting mechanism fails, it will affect the performance of the wireless charging function. In order to facilitate the vehicle end to troubleshoot the faults of the lifting mechanism, the BDC causes a fault in the lifting mechanism and sets it to the corresponding fault state so that the user can troubleshoot the faults of the lifting mechanism. Specifically, in addition to the above steps S101 and step S102, the method provided in this embodiment may further include the following step S701:

[0080] Step S701: Perform a fault detection on the lifting mechanism, and when a fault is detected in the lifting mechanism, set the fault status code of the lifting mechanism to the corresponding fault status; wherein, the fault includes a system fault and / or a power supply fault.

[0081] In this embodiment, the BDC performs a fault detection on the lifting mechanism, mainly including the detection of system faults and power supply faults of the lifting mechanism.

[0082] Optionally, for the detection of system faults of the lifting mechanism, fault detection can be performed through the control information with the lifting mechanism (such as when the power supply is normal, the lifting mechanism does not respond to the BDC's descending instruction) or the initialization state (such as the initialization state is abnormal denoraml). Or, when a system fault is detected, set the fault status corresponding to the system fault code (Diagnostic Trouble Code, DTC) of the ELM. Further, when the BDC schedules that the lifting mechanism has no system fault and the initialization state is noraml, it can be set as a historical fault and can be cleared through a diagnostic instrument or 40 power-on and power-off cycles.

[0083] Optionally, for the detection of power supply faults of the lifting mechanism, it can include that when there is an open circuit fault or a voltage fault in the lifting mechanism, when there is an open circuit fault or a voltage fault, set the ELM electrical fault DTC. When the BDC schedules that the ELM has no open circuit fault and voltage fault, it is set as a historical fault and cleared through a diagnostic instrument or 40 power-on and power-off cycles.

[0084] Exemplarily, Figure 8 It shows the simultaneous detection of system faults and power supply faults of the lifting mechanism. In some embodiments, other fault detections can also be performed on the lifting mechanism, such as the detection of whether the lifting speed meets the standard, etc. This embodiment does not make special limitations on this.

[0085] Through the above technical solution, by performing a fault detection on the lifting mechanism and setting the corresponding fault code status according to the detection result, the self-diagnosis function of the wireless charging device is realized, and it is convenient for users to troubleshoot faults of the lifting mechanism, improving the performance of the wireless charging device.

[0086] Figure 9It is a schematic flowchart of another control method for an in-vehicle wireless charging device provided by an embodiment of the present application. Considering that the current wireless charging system usually lacks the function of reminding users to pick up the device to be charged (such as a mobile phone). When the user leaves the vehicle, the mobile phone may be left on the charging panel and forgotten to be taken away, which may cause the user to miss important message notifications on the mobile phone, thus affecting the user's charging experience. Therefore, this embodiment provides a forgetting reminder function for the wireless charging device. Specifically, in addition to the above steps S101 and S102, after step S102, this embodiment may further include step S901:

[0087] Step S901: When the vehicle equipped with the in-vehicle wireless charging device meets a preset condition, generate a prompt message for reminding the user to pick up the device to be charged; wherein, the preset condition includes at least one of the following: the driver's door of the vehicle is in an open state; the driver's seat belt buckle of the vehicle is in an unfastened state; the vehicle is in a parking gear state; the in-vehicle wireless charging device is in a charging state.

[0088] Optionally, the preset condition can be a prerequisite for generating the prompt message, and a trigger condition for the driver's seat being empty can be set. Here, the driver's seat being empty in this embodiment means that the driver's seat changes from being occupied to unoccupied, which can be detected by a weight sensor on the driver's seat or other means and transmitted to the BDC.

[0089] Exemplarily, as shown in Figure 10 When the prerequisite conditions (a&b&c&d&e) are met: a. The BDC is in the ON gear (e.g., BCM_PowerStatusFeedback == 0x2); b. The driver's door is in an open state; c. The driver's seat belt buckle status is "Unbuckle" (e.g., SrsDrvrBucSwtSts = 0x1); d. The vehicle is in the P gear (e.g., VcuGearPosn = 0x1); e. The wireless charging area on the driver's side is in a charging state || the wireless charging area on the passenger's side is in a charging state; determine whether the trigger condition is reached: the driver's seat status changes from occupied to unoccupied. If so, execute the logic and output: a. Send "Mobile phone forgotten reminder" as "Remind" to the Cockpit Domain Controller (CDC) (e.g., BDC_PhoneInCarRemind == 0x1) (it can be in 3 cycles). Among them, the reminder method can be that the CDC controls the horn to sound continuously for 5 times to remind the user that the mobile phone is left on the charging board.

[0090] In some embodiments, the preconditions may also be other combinations of the above a, b, c, d, and e, or any one of them. The preconditions of a&b&c&d&e above are only taken as one example of this application. In addition, those skilled in the art can also adaptively determine other preset conditions in combination with actual applications, and this embodiment does not make special limitations on this.

[0091] Through the above technical solutions, when the user is about to leave the vehicle, a reminder for the device to be charged can be realized, effectively avoiding the problem that the user misses important message notifications on the mobile phone, and improving the user's charging experience and interaction experience.

[0173] In summary, in this embodiment, by adding a lifting mechanism to the wireless charging module, when the wireless charging panel detects a metal mobile phone, the wireless charging panel will automatically descend to a certain position, reaching the virtual lower limit position. When the mobile phone is removed, the wireless charging panel will automatically rise to a certain position, reaching the virtual upper limit position. When the number of movements of the position state of the wireless charging lifting mechanism from the stopped state to the non-stopped state reaches the preset number, by performing a position calibration action on the lifting mechanism, it can effectively ensure that the position of the lifting mechanism will not have a large deviation during the continuous up and down process, thus effectively solving the problem that it is difficult to prevent the mobile phone from falling off during charging due to position deviation and other problems; by setting an anti-play protection function to reduce the loss caused by the frequent lifting of the lifting mechanism; by the fault self-diagnosis function of the wireless charging lifting mechanism, improving the wireless charging performance and the fault troubleshooting function; by setting a forgetting reminder function to remind the user to pick up the device to be charged in time when about to leave, improving the user experience.
