Description

Technical Field

[0001] The present application relates to the field of vehicle intelligent technology, and more specifically, to a method, device, vehicle and computer-readable storage medium for reminding a person to forget a device. Background Art

[0002] At present, the application of mobile phone wireless charging technology in automobiles has become very popular, and many vehicles are equipped with mobile phone wireless charging devices. However, vehicle users tend to forget their mobile phones placed on the mobile phone wireless charging devices for charging when leaving the vehicle.

[0003] Therefore, there is an urgent need for a device forgotten reminder method that can detect whether a mobile phone is still forgotten in the car with low power consumption after the vehicle is turned off. Summary of the invention

[0004] In response to the above needs, the present application proposes a device forgotten reminder method, device, vehicle and computer-readable storage medium.

[0005] In a first aspect, an embodiment of the present application provides a device forgotten reminder method, which is applied to a vehicle, wherein the vehicle includes a wireless charging device, and the wireless charging device is provided with a wireless charging area. The method includes: if it is detected that the vehicle is in an off state, performing a metal object detection operation on the wireless charging device; if the detection result of the metal object detection operation is that there is a metal object in the wireless charging area, issuing a device forgotten reminder to the vehicle user.

[0006] In the second aspect, an embodiment of the present application also provides a device for reminding a user of a forgotten device, which is applied to a vehicle. The vehicle includes a wireless charging device, and the wireless charging device is provided with a wireless charging area. The device includes a detection module and a sending module. The detection module is used to perform a metal object detection operation on the wireless charging area if it is detected that the vehicle is in an ignition-off state; the sending module is used to send a device forgotten reminder to the vehicle user if the detection result of the metal object detection operation is that there is a metal object on the wireless charging area.

[0007] In a third aspect, an embodiment of the present application further provides a vehicle, characterized in that the vehicle includes: a wireless charging device, the wireless charging device being provided with a wireless charging area; one or more processors; a memory; one or more applications, wherein one or more applications are stored in the memory and configured to be executed by one or more processors, and one or more programs are configured to execute the above method.

[0008] In a fourth aspect, an embodiment of the present application further provides a computer-readable storage medium, which stores a program code executable by a processor, and when the program code is executed by the processor, the processor executes the above method.

The detection result of the presence of a metal object on the wireless charging area is obtained through the metal object detection operation, and a device forgotten reminder is issued based on the detection result. Since the metal object detection only requires a very small current to pass through the wireless charging device to obtain the detection result, the energy consumption required to detect whether a device is forgotten on the wireless charging device when the vehicle uses a battery to power the wireless charging device after the ignition is turned off is greatly reduced, and the power management of the vehicle after the ignition is turned off is optimized.

[0019] In order to make those skilled in the art better understand the present application scheme, the technical scheme in the present application embodiment will be clearly and completely described below in conjunction with the drawings in the present application embodiment. Obviously, the described embodiment is only a part of the present application embodiment, rather than all the embodiments. The components of the present application embodiment usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiment of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0020] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] In the existing vehicle forgotten reminder scheme, it is generally to determine whether the mobile phone is still present through the status of the wireless charging device after the vehicle is turned off. For example, if the status of the wireless charging device is charging or fully charged, it is determined that the mobile phone is still on the charging plate. However, this requires that the vehicle still needs to provide sufficient power to the wireless charging device when the engine is turned off to keep it in a rechargeable state. In addition, in order to improve the charging efficiency, the charging power of the wireless charging device is mostly above 45W. When the vehicle is turned off, the vehicle itself will cut off the high-voltage power input and switch to battery power supply. In order to avoid the situation where the battery is low and the vehicle cannot be started, the vehicle side will strictly limit the power of each electrical appliance after the high voltage is cut off. Therefore, if the battery is still used to provide high power to the wireless charging device to keep it in a rechargeable state when the engine is turned off, it is not conducive to power saving and power management when the vehicle is turned off.

[0022] See also Figure 1 , Figure 1 A flowchart of a device forgotten reminder method shown in an embodiment of the present application is shown. The method is applied to Figure 7 The vehicle 700 shown includes a wireless charging device 710, and the wireless charging device 710 is provided with a wireless charging area. The method includes:

[0023] S101: If it is detected that the vehicle is in an ignition-off state, a metal object detection operation is performed on the wireless charging device.

[0024] The vehicle may be an electric vehicle or a fuel vehicle, such as a car, a bus, or a truck. The wireless charging device on the vehicle is used to wirelessly charge the user's electronic devices, which may include mobile phones, tablet computers, and other devices that support wireless charging. Specifically, the wireless charging device converts electromagnetic wave energy into electrical energy through electromagnetic induction energy coupling between the transmitting coil and the receiving coil in the electronic device, and continuously supplies power to the electronic device. The wireless charging device 710 is provided with a wireless charging area, and the transmitting coil of the wireless charging device is provided in the wireless charging area. The electronic device to be charged can be placed in the wireless charging area, thereby charging the electronic device.

[0025] It can be understood that the wireless charging device is powered by the vehicle. The ignition system of the vehicle generally has the following gears: ACC, ON and OFF. The ACC gear means that some of the electrical equipment of the vehicle, such as lights and audio, are powered on. The ON gear means that the vehicle engine and all the lines of the vehicle are connected. The OFF gear means that the engine is turned off. Further, when the vehicle is in the ACC gear or the ON gear, it indicates that the vehicle is in a waiting state or a starting state. At this time, the wireless charging equipment is connected to the power supply and the power input is provided by the high voltage. When the vehicle is in the OFF gear, it indicates that the vehicle is in a flameout state. At this time, the vehicle cuts off the high voltage input and supplies power to certain electrical appliances on the vehicle from the battery. As an implementation method, when it is detected that the vehicle is in a flameout state, the state of the vehicle at the last moment is obtained. If the state of the vehicle at the last moment is the waiting state (ACC gear), it indicates that the vehicle is switched from the waiting state (ACC state) to the flameout state; if the state of the vehicle at the last moment is the starting state (ON gear), it indicates that the vehicle is switched from the starting state (ON state) to the flameout state. At this time, it is judged that the vehicle is detected to be in a flameout state, and a metal object detection operation is performed on the wireless charging device.

[0026] As an implementation mode, performing a metal object detection operation on a wireless charging device may refer to detecting whether there is a metal object on the wireless charging area of ​​the wireless charging device. Furthermore, a quality factor (Q value) detection method may be used to detect whether there is a metal object on the wireless charging area of ​​the wireless charging device. Specifically, the Q value is calculated by measuring the power transmission efficiency between the transmitting coil of the wireless charging device and the receiving coil of the electronic device. Thus, during the process of the wireless charging device sending electromagnetic waves, the Q value may be detected to determine whether there is a metal object within the electromagnetic wave transmission range. When the Q value exceeds a preset threshold, it is determined that there is a metal object on the wireless charging area of ​​the wireless charging device. The preset threshold may be set to the Q value measured when there is no metal object on the wireless charging area of ​​the wireless charging device. In this way, once there is a metal object on the wireless charging area, the detection result may be output, making the metal object detection result more sensitive. The preset threshold may also be set to the Q value measured when a mainstream electronic device on the market is placed on the wireless charging area of ​​the wireless charging device. In this way, the metal object detection result may be prevented from being misreported due to interference from some non-electronic equipment metal objects such as keys, thereby improving the accuracy of the metal object detection result.

[0027] As an implementation method, the presence of metal objects in the wireless charging area can be detected by detecting the magnetic field strength of the wireless charging area of ​​the wireless charging device. Specifically, when the wireless charging area is powered on, the direct current provided by the vehicle is rectified into a high-frequency alternating current. The alternating current will generate an alternating magnetic field due to electromagnetic induction, and the metal objects will generate an induced magnetic field in the alternating magnetic field, thereby interfering with the original alternating magnetic field. Therefore, when a change in the magnetic field strength in the wireless charging area is detected, it can be determined that there is a metal object in the wireless charging area of ​​the wireless charging device.

[0028] S102: If the detection result of the metal object detection operation is that there is a metal object on the wireless charging area, a device forgotten reminder is issued to the vehicle user.

[0029] In this embodiment, if the detection result of the metal object detection operation is that there is a metal object in the wireless charging area, the vehicle control system issues a device forgotten reminder to the vehicle user. Specifically, the vehicle control system may issue a reminder message based on the metal object detection result, so that the audio device receives the reminder message and sends a voice broadcast reminder to the user, or the instrument panel display receives the reminder message and sends a text reminder to the user. The vehicle control system may also cause the electronic device itself to emit a sound or vibration reminder through an app on the electronic device that connects the device to the vehicle.

[0030] It is understandable that the metal object detection operation does not require the wireless charging device to be maintained in a charging state, but only requires the wireless charging device to be powered on, and the Q value detection or magnetic field detection method can be used to detect the Q value change or magnetic field change of the wireless charging device to determine whether there is a metal object in the wireless charging area of ​​the wireless charging device. When there is a metal object in the wireless charging area, it is determined that the vehicle user has forgotten the device in the wireless charging area and a reminder is issued, so that the vehicle does not need to maintain the wireless charging device in a charging state after the engine is turned off, which greatly reduces the power consumption of the wireless charging device and is more conducive to power management after the vehicle is turned off. In addition, since the power consumption required for metal object detection is very low, the vehicle can continuously detect whether there is a device forgotten in the vehicle and issue a reminder for a long time while using the battery to power the vehicle's electrical appliances, thereby improving the relevant functional experience.

[0031] Therefore, the present application provides a device forgotten reminder method, which is applied to a vehicle, wherein the vehicle includes a wireless charging device, and the wireless charging device is provided with a wireless charging area. The method includes: if it is detected that the vehicle is in an off state, performing a metal object detection operation on the wireless charging device; if the detection result of the metal object detection operation is that there is a metal object in the wireless charging area, issuing a device forgotten reminder to the vehicle user. The detection result of the presence of a metal object in the wireless charging area is obtained through the metal object detection operation, and a device forgotten reminder is issued based on the detection result. Since the metal object detection only requires a very small current to pass through the wireless charging device to obtain the detection result, the energy consumption required for detecting whether a device is forgotten on the wireless charging device when the vehicle uses a battery to power the wireless charging device is greatly reduced, and the power management after the vehicle is turned off is optimized.

[0032] See also Figure 2 , Figure 2 A flowchart of another device forgotten reminder method shown in an embodiment of the present application is shown, which is applied to a vehicle, and the method includes:

[0033] S201: If it is detected that the vehicle is in an ignition-off state, obtain the magnetic field strength in the wireless charging area.

[0034] As an implementation method, the magnetic field strength in the wireless charging area can be measured by building a fluxmeter or electromagnetic potentiometer into the wireless charging device. Specifically, if the moment when the power supply of the wireless charging device is detected to be changed to the vehicle battery is taken as the initial moment, the magnetic field strength in a wireless charging area can be obtained at the initial moment, and the presence of a metal object can be judged based on the magnetic field strength obtained at the initial moment, thereby shortening the time for obtaining the metal object detection result and thus improving the reminder speed of the device forgetting reminder; the magnetic field strength in the wireless charging area can also be continuously obtained within a preset time after the initial moment, and the presence of a metal object can be judged based on the magnetic field strength obtained within the preset time, thereby improving the accuracy of the metal object detection result and thus improving the accuracy of the device forgetting reminder.

[0035] S202: If the magnetic field strength is not within a rated magnetic field strength range, it is determined that a metal object is detected in the wireless charging area.

[0036] Among them, the rated magnetic field strength range refers to the range obtained after the rated magnetic field strength is floated above and below the deviation value. Furthermore, the magnetic field strength when no metal objects are placed on the wireless charging area can be measured when the vehicle leaves the factory, and the magnetic field strength can be used as the rated magnetic field strength. The deviation value can be measured by placing other metal objects other than commonly used electronic devices on the wireless charging area for multiple times and taking the average value to eliminate the interference of metal debris on the magnetic field. Furthermore, after the power supply of the wireless charging device is changed to the vehicle battery, the magnetic field strength on the wireless charging area is obtained, and the obtained magnetic field strength is compared with the rated magnetic field strength range. If the magnetic field strength is not within the rated magnetic field strength range, it can be explained that there is a metal object in the wireless charging area, that is, the device is forgotten, when the interference of metal debris is eliminated.

[0037] S203: If the detection result of the metal object detection operation is that there is a metal object on the wireless charging area, a device forgotten reminder is issued to the vehicle user.

[0038] The implementation of step S203 may refer to the implementation of step S102 in the above embodiment, and will not be described in detail here.

[0039] Therefore, the present application provides a device forgotten reminder method, which is applied to a vehicle, wherein the vehicle includes a wireless charging device, and the wireless charging device is provided with a wireless charging area. The method includes: if it is detected that the vehicle is in an ignition-off state, obtaining the magnetic field strength on the wireless charging area, and if the magnetic field strength is not within the rated magnetic field strength range, determining that a metal object is detected on the wireless charging area, and if the detection result of the metal object detection operation is that a metal object exists on the wireless charging area, issuing a device forgotten reminder to the vehicle user. By detecting the magnetic field strength on the wireless charging area and comparing it with the rated magnetic field strength range to obtain the detection result, it is possible to determine the presence of a metal object on the wireless charging area while eliminating the interference of metal debris, and greatly reduce power consumption.

[0040] See also Figure 3 , Figure 3 A flowchart of another device forgotten reminder method shown in an embodiment of the present application is shown, which is applied to a vehicle, and the method includes:

[0041] S301: If it is detected that the vehicle is in an ignition-off state, obtain the magnetic field strength in the wireless charging area.

[0042] S302: If the magnetic field strength is not within the rated magnetic field strength range, determine the starting time; determine whether the magnetic field strength in the wireless charging area is continuously detected to be not within the rated magnetic field strength range within a first preset time period after the starting time; if so, determine that a metal object is detected in the wireless charging area.

[0043] Specifically, if the magnetic field strength obtained at the initial moment when it is detected that the power supply of the wireless charging device is changed to the vehicle battery is not within the rated magnetic field strength range, then this moment is determined as the starting moment, and the magnetic field strength on the wireless charging area is continuously obtained within the first preset time after the starting moment. If the magnetic field strength on the wireless charging area is not within the rated magnetic field strength range within the first preset time, it is determined that a metal object is detected in the wireless charging area. Further, the first preset time can be set by the user, so as to avoid the situation where the user has the habit of resting in the vehicle after turning off the engine and still places the mobile phone on the wireless charging device to charge, and the device forgotten reminder issued disturbs the user. In addition, by determining that a metal object is detected in the wireless charging area when the magnetic field strength is not within the rated magnetic field strength range during the continuous period, it can also avoid the problem of other metal objects other than electronic devices interfering with the magnetic field of the wireless charging device at a certain moment and causing false alarms.

[0044] S303: If the detection result of the metal object detection operation is that there is a metal object on the wireless charging area, a device forgotten reminder is issued to the vehicle user.

[0045] The specific implementation of step S301 and step S303 may refer to the relevant implementation of the above embodiment, and will not be described in detail here.

[0046] Therefore, an embodiment of the present application provides a device forgotten reminder method. When the magnetic field strength in the wireless charging area is not within the rated magnetic field strength range, the method first determines the starting time, and judges whether the magnetic field strength in the wireless charging area is continuously detected to be not within the rated magnetic field strength range within a first preset time after the starting time, that is, the presence of metal objects in the wireless charging area is continuously detected within the first preset time, and then obtains the detection result of the metal object detected in the wireless charging area, thereby improving the accuracy of the metal object detection result, reducing the false alarm rate, and enhancing the functional experience.

[0047] See also Figure 4 , Figure 4 A flowchart of another device forgotten reminder method shown in an embodiment of the present application is shown, which is applied to a vehicle, and the method includes:

[0048] S401: If it is detected that the vehicle is in an ignition-off state, obtain the working mode of the wireless charging device.

[0049] The wireless charging device has two working modes: idle mode and charging mode. The charging mode refers to the state where the wireless charging device is charging the electronic device or the electronic device is fully charged, and the idle mode refers to the state where the wireless charging device is not charging the electronic device. As an implementation method, the working mode of the wireless charging device can be determined by detecting the current value and voltage value in the transmitting coil of the wireless charging device.

[0050] S402: If the working mode is the idle mode, turn off the wireless charging device.

[0051] It is understandable that if the wireless charging device is in idle mode before the vehicle is turned off, it means that there is no electronic device on the wireless charging device before the vehicle is turned off. Therefore, there is no need to start metal object detection when the vehicle is turned off. Directly turning off the wireless charging device can save battery power and optimize power distribution.

[0052] S403: If the working mode is the charging mode, perform a metal object detection operation on the wireless charging area.

[0053] S404: If the detection result of the metal object detection operation is that there is a metal object on the wireless charging area, a device forgotten reminder is issued to the vehicle user.

[0054] The implementation of steps S403 and S404 may refer to the implementation of steps S101 and S102 in the above embodiment, and will not be described in detail here.

[0055] Therefore, the present application provides a device forgotten reminder method. If it is detected that the vehicle is in an ignition-off state, the working mode of the wireless charging device is obtained. If the working mode of the wireless charging device is an idle mode, the wireless charging device is turned off. The metal object detection operation is performed on the wireless charging area only when the working mode is a charging mode. The metal object detection operation is selectively performed in combination with the working mode of the wireless charging device before the vehicle is turned off. This not only saves energy consumption, but also avoids the problem of false alarms caused by detecting other metal objects during metal object detection when there is no device charging, thereby improving the functional usage experience.

[0056] See also Figure 5 , Figure 5 A flowchart of another device forgotten reminder method shown in an embodiment of the present application is shown, which is applied to a vehicle, and the method includes:

[0057] S501: If it is detected that the vehicle is in an ignition-off state, a metal object detection operation is performed on the wireless charging area.

[0058] The implementation of step S501 may refer to the above embodiment and will not be described in detail here.

[0059] S502: If the detection result of the metal object detection operation is that there is a metal object in the wireless charging area, obtain the main driver door status, and the main driver door status includes an open state and a closed state.

[0060] Among them, the vehicle control system can obtain the signal of the main driver's door being opened to determine whether the main driver's door is in an open state or a closed state. Furthermore, when the detection result of the metal object detection operation is that there is a metal object in the wireless charging area, the status of the main driver's door before and after this moment is obtained, so as to determine whether to issue a device forgotten reminder based on the status of the main driver's door.

[0061] As an implementation method, the state of the main driver's door can be obtained in the following ways: for a door with a mechanical switch, when the door is closed, the switch will trigger and close the circuit, and the state of these switches can be detected to determine whether the door is closed; or, a magnetic sensor is installed between the door and the body, and when the door is closed, the sensor will sense the change of the magnetic field, and the signal of the magnetic sensor can be detected to determine whether the door is closed. Alternatively, a micro switch is installed on the door, and when the door is closed, the switch will be pressed, and the state of the micro switch can be detected to determine whether the door is closed. Alternatively, for a vehicle using a vehicle bus system, the vehicle bus system can monitor the state of the door, and obtain the data of the door switch state by reading the information of the vehicle bus system. Alternatively, a camera or other visual sensor is used to monitor the position and state of the door in real time, and image processing and analysis can be used to determine whether the door is closed. The above methods can be used alone or in combination to obtain more accurate door state detection results, and the specific method to be selected is determined according to actual needs and vehicle design.

[0062] S503: If the main driver's door is in the open state, a device forgotten reminder is issued to the vehicle user.

[0063] Among them, the main driver's door state is open state can mean that when the detection result of the metal object detection operation is obtained that there is a metal object on the wireless charging area, the main driver's door state is open state, which means that the car door is open, and sending a device forgotten reminder to the vehicle user can help the user find that the device is forgotten before leaving the vehicle. Furthermore, the main driver's door state can be obtained again before the metal object detection result is obtained. If the main driver's door state is closed, it means that the user has opened the car door, and the reminder can be more accurately based on the user's action.

[0064] S504: If it is detected that the state of the main driver's door is switched from the open state to the closed state, a metal object detection operation is performed on the wireless charging area again.

[0065] After the device forgotten reminder has been issued to the vehicle user based on the metal object detection result and the main driver's door status, the main driver's door status can continue to be obtained. If it is detected that the main driver's door status is switched from an open state to a closed state, the metal object detection operation is performed on the wireless charging device again to determine whether the user has taken the electronic device away. The implementation method of performing the metal object detection operation can refer to the above embodiment and will not be repeated here.

[0066] S505: If there is still a metal object on the wireless charging area, determine the duration of the device forgetting reminder.

[0067] Among them, the method of judging whether there is still a metal object in the wireless charging area can refer to the above embodiment. As an implementation mode, if the main driver's door state is switched from the open state to the closed state, and the detection result of performing the metal object detection operation on the wireless charging area again is that there is still a metal object in the wireless charging area, the method of issuing the device forgotten reminder can be that the vehicle audio equipment issues a prompt sound, and the device forgotten reminder is continuously issued during the continuous reminder duration. Furthermore, the prompt sound volume at this time can be higher than the prompt sound issued by the device forgotten reminder when the detection result of the first metal object detection operation is that there is still a metal object in the wireless charging area, so as to remind the user who leaves the vehicle that the device is forgotten.

[0068] S506: If the duration of the continuous reminder is longer than a second preset duration, stop outputting the device forgetting reminder.

[0069] Among them, the second preset time length can be set by the user. When the continuous reminder time length is greater than the second preset time length, the output device forgets to remind that the vehicle has been forgotten, which can save vehicle energy.

[0070] Therefore, in an embodiment of the present application, if it is detected that the vehicle is in an ignition-off state, the metal object detection result is combined with the main driver's door state to issue a device forgotten reminder. Since the change in the main driver's door state indicates the state of the vehicle user, for example, whether he is still in the vehicle or has left the vehicle, after determining that there is a metal object on the wireless charging area of ​​the wireless charging device, the device forgotten reminder is further issued in combination with the vehicle user's state, so that the device forgotten reminder is more in line with the user's actual state, thereby improving the function usage experience.

[0071] See also Figure 6 , Figure 6 The structure block diagram of a device forgotten reminder device proposed in one embodiment of the present application is shown, which is applied to Figure 7 The vehicle 700 shown includes a wireless charging device 710, and the wireless charging device 710 is provided with a wireless charging area. The apparatus 600 includes:

[0072] The detection module 601 is used to perform a metal object detection operation on the wireless charging area if it is detected that the vehicle is in an ignition-off state.

[0073] The sending module 602 is used to send a device forgotten reminder to the vehicle user if the detection result of the metal object detection operation is that there is a metal object on the wireless charging area.

[0074] Optionally, the detection module 601 is further configured to obtain the magnetic field strength in the wireless charging area, and if the magnetic field strength is not within a rated magnetic field strength range, it is determined that a metal object is detected in the wireless charging area.
