[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0030] The following description, with reference to the accompanying drawings, outlines a device forgetting reminder method, apparatus, vehicle, storage medium, and application product according to embodiments of this application. Addressing the problems mentioned in the background section, this application provides a device forgetting reminder method. This method, by monitoring changes in power mode, electrical signals from multiple seats in a vehicle, and the quality factor of the in-vehicle wireless charging device, can determine whether a device has been forgotten. This improves the accuracy and reliability of the forgetting reminder function, enhancing user convenience and safety by promptly reminding the user.

[0031] Before introducing this application, the interactive system involving the forgetting reminder is described as shown in Figure 1. It mainly includes: an in-vehicle wireless charging module for mobile phones, a vehicle domain controller, a seat cushion module, and an in-vehicle communicator (referred to as BOX). When the power mode switches from ON to ACC power off, and the seat cushion module detects that a person has left the seat and opened the door to get out of the car, the mobile phone forgetting reminder function is automatically triggered. By detecting whether there is a pressure sensor signal in different seat cushion modules, the in-vehicle wireless charging module sends a signal of the item left behind to the in-vehicle remote communicator. The mobile phone remote APP then broadcasts a reminder to the user that there is an item left on the vehicle seat, ensuring the safety of the user's property.

[0032] Specifically, Figure 2 is a flowchart illustrating a device forgetting reminder method provided in an embodiment of this application.

[0033] As shown in Figure 2, the forgetting reminder method of this device includes the following steps:

[0034] In step S101, the state switching of the vehicle power mode is detected.

[0035] It is understood that the embodiments of this application can monitor the state changes of the vehicle power mode so as to trigger the forgetting reminder function under specific circumstances. As shown in Figure 3, the state switching includes: switching from the off state to the target state, switching from the off state to the on state; switching from the target state to the off state, switching from the target state to the on state; switching from the on state to the target state, and switching from the on state to the off state.

[0036] In one embodiment of this application, before detecting the state switch of the vehicle power mode, the method further includes: detecting the vehicle's gear and speed; if the gear is in the target gear and the speed is less than a preset speed, then detecting the state switch of the vehicle power mode.

[0037] The target gear can be neutral (N) or park (P), and the preset speed can be 4 km / h.

[0038] Specifically, in this application embodiment, the vehicle must meet a series of specific states before triggering the forgetting reminder function. These states ensure that the forgetting reminder function is activated only under appropriate circumstances. In actual execution, this application embodiment can detect the vehicle's gear and speed. The vehicle speed must be less than 4 km / h, thereby ensuring that the vehicle is stationary or moving very slowly, making it more likely that the power mode will be switched after parking. The gear should be in N or P gear, which conforms to the normal operation of the vehicle when parked.

[0039] Furthermore, the power system in this application can be in the VehpwrMod / Keysts = 0x1:ON state (key learned and powered on). This means the vehicle's power mode has been switched to "ON," indicating the vehicle is ready to start the engine. Here, 0x1 is a hexadecimal code representing the power mode as "ON." "Key learned and powered on" indicates that the vehicle has recognized and learned the key's presence, and the key has been used to power it. This is accomplished through the vehicle's smart key system, typically meaning the key is already inside the vehicle or close enough for the vehicle to detect its presence.

[0040] In step S102, when the state switching meets the preset conditions, the forgetting reminder function is triggered when the person in the vehicle gets off, and the electrical signals of multiple seats in the vehicle and the quality factor emitted by the vehicle wireless charging device are received.

[0041] The preset conditions include: the vehicle power mode switching from the ON state to the target state (ACC state) and / or the vehicle power mode switching from the OFF state to the target state.

[0042] Based on the above embodiments, if the vehicle's seat cushion module detects that a person has left (pressure sensor changes electrical signal NO1), the driver's door changes from closed to open, and the brake pedal is not pressed, the BDM controller starts to execute signal output, sends the power status VehpwrMod / Keysts = 0x1:ACC, and after a 1-second delay, the vehicle power switches to the accessory (ACC) state.

[0043] When the vehicle-mounted wireless charging module reads the power status signal and the occupant departure signal sent by the BDM control and seat cushion module from the vehicle's CAN bus, the conditions for triggering the forgotten reminder function are met. The vehicle needs to monitor the electrical signals on multiple seats and the quality factor (Q value) emitted by the vehicle-mounted wireless charging device to determine if any device has been forgotten.

[0044] In step S103, it is determined whether there is a forgotten target device based on the electrical signal and / or quality factor, and a forgetting reminder is given for the forgotten target device.

[0045] It is understood that the embodiments of this application can determine whether there is a forgotten charging device (such as a mobile phone) in an infinite area of ​​the vehicle based on the quality factor, and can determine whether there is a forgotten object (such as a heavy object that meets certain conditions) on the seat of the vehicle based on the electrical signal.

[0046] In one alternative implementation, the electrical signal is a pressure sensing signal provided by the seat in the vehicle. The signal strength of this pressure sensing signal is correlated with the weight borne by the seat. This correlation can be implemented as at least one of a linear function, a quadratic function, an exponential function, a logarithmic function, etc. This application does not limit the type of function fitted to the correlation. Furthermore, the signal strength of the pressure sensing signal and the weight borne by the seat can be positively or negatively correlated.

[0047] Furthermore, multiple piezoelectric sensors are deployed on the seat, each providing a pressure sensing signal. When the electrical signal meets the prompting conditions, a reminder is sent to the forgotten target device.

[0048] The indications include: the matrix elements in the piezoelectric signal matrix do not exhibit axial or centrosymmetric distribution characteristics; the values ​​of the matrix elements in the piezoelectric signal matrix are the signal strengths of the pressure sensing signals, and the matrix positions of the pressure sensing signals are determined based on the positions of the piezoelectric sensors within the seat. For example, assuming a seat with nine piezoelectric sensors arranged in three rows and three columns, the piezoelectric signal matrix is ​​three rows and three columns in size. The pressure sensing signal provided by the piezoelectric sensor located in the upper left corner of the seat is the value of the element in the first row and first column of the piezoelectric signal matrix. When the matrix elements do not exhibit axial or centrosymmetric characteristics, the weight load on the seat is unevenly distributed, significantly different from the characteristic of a person sitting in the center of the seat. This allows us to determine that the weight load on the seat is the target device.

[0049] And / or, the indication conditions include that the number of first matrix elements in the piezoelectric signal matrix exceeds a first threshold, and the matrix value of the first matrix element is a first value, which indicates that the pressure received by the piezoelectric sensor is empty or less than a first preset pressure. If the number of first matrix elements in the piezoelectric signal matrix exceeds the first threshold, the weight borne by the seat is a relatively small item compared to the size of the seat, significantly different from the weight covering most of the seat when a person is seated, thus determining that the weight borne by the seat is a forgotten target device.

[0050] When the vehicle-mounted wireless charging module reads the power status VehpwrMod / Keysts=0x1:ACC and the driver's side no-driver signal NO1 from the vehicle's CAN bus, it starts Q-value detection to check if there is a mobile device above the module. If a mobile device is detected, it will issue a reminder.

[0051] Furthermore, if no mobile device is detected, the in-vehicle wireless charging module in this embodiment will not send a mobile device alert signal to the host. If the seat cushion module detects one or more items left on top of the vehicle, it sends an electrical signal Y1 to the in-vehicle wireless charging module. The wireless charging module then sends a heavy object-forgottenFunSts signal to the BOX. Upon receiving this signal, the BOX will remotely alert the user via a mobile app to the presence of a heavy object in the vehicle, preventing potential property loss.

[0052] As another possible implementation, the power mode switches from OFF to ACC. When the user unlocks the vehicle and opens the door, the conditions for switching the power mode from OFF to ACC are met, and VehpwrMod / Keysts=0x1:ACC will be sent. If the user places their phone in the wireless charging area at this time, the vehicle's wireless charging module will detect the phone with its Q value. However, since the driver's seat cushion module detects the presence of the driver, the forget reminder function will not be triggered at this time, and the charging mode will only be entered.

[0053] In addition, when the vehicle-mounted wireless charging module reads the power status signal and the personnel departure signal sent by the BDM control and seat cushion module from the vehicle's CAN bus, and the vehicle-mounted wireless charging module detects that a mobile phone is placed above the controller, the conditions for triggering the forgetting reminder function are met. The vehicle-mounted wireless charging module sends the corresponding ID message DVD_SET_CWC_PhoneforgottenFunSts to the host. When the host receives the message sent by the vehicle-mounted wireless charging module, it selects whether to announce 'the mobile device is still in the vehicle' based on the status (the forgetting reminder is turned off when the value is 1, and turned on when the value is 2).

[0054] It should be noted that all in-vehicle wireless charging modules use electromagnetic induction as their charging principle. The operating frequency of these modules is similar to, almost identical to, the frequency at which the BDM controller searches for the vehicle key. To avoid issues where the vehicle cannot find the key, when the power mode is ACC and the key has been learned, the BDM controller's key-finding function is only triggered when the user presses the brake pedal. Simultaneously, it sends key-finding signals SmartSystemWarning2_2 / SmartSystemWarning2_0 / SmartSystemWarning1_1 (this signal is only sent when the vehicle's power mode is ON; this signal indicates a non-OFF state, key-finding operation with the door closed; if the key is not found, an alarm will sound to remind the user). In one example, when the in-vehicle wireless charging module detects any of these signals on the vehicle's CAN bus, it disables the forget-the-key reminder function and enters sleep mode to prevent the key-finding signal from mistakenly triggering the forget-the-key reminder function. In another example, when the vehicle wireless charging module detects any of the above signals on the vehicle's CAN bus, it disables the charging function of the charging module to prevent the electromagnetic induction signal of the charging module from interfering with the key finding operation and to avoid the vehicle falsely reporting a key not found fault.

[0055] In one embodiment of this application, determining whether a forgotten target device exists based on a quality factor includes: identifying the range of variation of the quality factor; if the range of variation reaches a preset threshold, then determining that a forgotten target device exists in the target area of ​​the vehicle-mounted wireless charging device.

[0056] The change in the Q value can be used to determine whether a device supporting wireless charging (such as a mobile phone) is placed in the charging area. By monitoring the range of Q value changes, it is possible to identify whether a target device has been left behind in the charging area. The preset threshold can be set based on the baseline Q value and the expected range of change, without specific limitations, such as setting a negative threshold. In actual implementation, this embodiment can continuously monitor the Q value. When no device is placed, the baseline Q value is recorded. When the Q value changes, the range of change is recorded. The range of change is compared with the preset threshold. When the Q value drops to a certain level, it indicates that a device has been placed in the charging area.

[0057] In one embodiment of this application, reminding a forgotten target device includes: controlling a vehicle to perform an optical reminder action; and / or controlling a vehicle to perform an acoustic reminder action; and / or pushing forgotten information of the target device to a preset terminal.

[0058] It is understood that the reminder method of this application can be an optical reminder device, such as flashing car lights; it can also be an acoustic reminder device that emits an alarm sound, such as the beeping sound of a device built into the vehicle; or it can send the forgotten information related to the target device to a preset terminal (such as a mobile phone), so that the user can view the information of all devices left in the car on the mobile phone and promptly remind the user to take appropriate action.

[0059] The device forgetting reminder method proposed in this application can determine whether a device has been forgotten by monitoring changes in power mode, electrical signals of multiple seats in the vehicle, and the quality factor of the in-vehicle wireless charging device. This improves the accuracy and reliability of the forgetting reminder function and enhances user convenience and safety by timely reminders.
