step S110, acquiring a current state of the vehicle-mounted wireless charging device, where the current state includes a charging state and a standby state.
In this embodiment, the in-vehicle wireless charging device mainly includes three states: off state, charging state, standby state. When the vehicle-mounted wireless charging device is successfully connected with the wireless charging mobile phone, the vehicle-mounted wireless charging device is in a charging state, and when the vehicle-mounted wireless charging device is powered on but is not connected with the equipment to be charged, the vehicle-mounted wireless charging device is in a standby state.
When the vehicle-mounted wireless charging device is in a charging state and a standby state, foreign object detection needs to be performed on the vehicle-mounted wireless charging device.
Step S120, based on the current state, determines a detection object for which foreign matter detection is directed.
In this embodiment, different foreign object detection strategies may be implemented based on different states of the in-vehicle wireless charging device. In the present application, different foreign object detection strategies are directed to different detection objects.
Specifically, when the in-vehicle wireless charging apparatus is in a standby state, the detection object may be a device to be charged and a metallic foreign object, thereby determining whether the device to be charged needs to be charged and whether there is an influence of the metallic foreign object. When the vehicle-mounted wireless charging device is in a charging state, because the vehicle-mounted wireless charging device is connected with the equipment to be charged, whether the equipment to be charged exists or not can be avoided, and only whether a metal foreign body exists or not is detected, so that the influence of the metal foreign body on the wireless charging process is avoided.
In this embodiment, corresponding detection methods may also be adopted for different detection objects.
Step S130, detecting whether the detection object exists in a preset range.
In practice, the preset range may be a charging area of the wireless charging apparatus, so that whether a metallic foreign object exists in the charging area of the wireless charging apparatus and whether a device to be charged exists can be detected.
In this embodiment, the metal foreign object detection may be implemented by any feasible method in the prior art, such as: q value detection method, infrared detection method, etc., and the present invention is not particularly limited thereto.

Therefore, in the embodiment of the invention, the alarm prompt is executed only when the equipment to be charged and the metal foreign matter exist in the preset range.
In the embodiment of the invention, a detection object for foreign matter detection is determined by acquiring the current state of vehicle-mounted wireless charging; detecting whether the detection object exists in a preset range or not; and when the detection result of the detection object is a preset result, executing alarm prompt. In the embodiment of the invention, the corresponding foreign matter detection strategy is executed by judging the current state of the vehicle-mounted wireless charging, the alarm prompt is executed only when the detection result is the preset result, and the alarm prompt can not be executed under other conditions, so that the energy consumption can be reduced.

In this embodiment, step S220 may specifically include: determining that the detection object is a metal foreign object in the charging state; in the standby state, it is determined that the detection object includes the metallic foreign matter and a device to be charged.
Specifically, when the in-vehicle wireless charging apparatus is in a standby state, the detection object may be a device to be charged and a metallic foreign object, thereby determining whether the device to be charged needs to be charged and whether there is an influence of the metallic foreign object. When the vehicle-mounted wireless charging device is in a charging state, because the vehicle-mounted wireless charging device is connected with the equipment to be charged, whether the equipment to be charged exists or not can be detected, and whether a metal foreign body exists or not is detected, so that the influence of the metal foreign body on the wireless charging process is avoided.
Step S230, detecting a quality factor Q value of the transmitting end of the wireless charging device; and if the Q value is reduced and is smaller than the preset threshold value, determining that the metal foreign matters exist in the preset range.
In this embodiment, the presence or absence of a foreign metal in a predetermined range is determined by a Q value detection method. And under the condition that the Q value is reduced and is smaller than a preset threshold value, representing that the metal foreign matters exist in a preset range, and obtaining a detection result of the metal foreign matters. Wherein the preset threshold is preset in advance by a technician.

Step S260, when the detection result of the detection object is not the preset result, no alarm prompt is executed; and/or when the detection result of the detection object is that the equipment to be charged exists but no foreign matter exists, performing wireless charging on the equipment to be charged.
In this embodiment, when the detection result is not the preset result, the alarm prompt is not executed. And, when detecting that the device to be charged exists within the preset range but no foreign object exists, specifically, may be: the Q value is larger than or equal to the preset value, the equipment to be charged is matched with the vehicle-mounted wireless charging device, and under the condition, the connection between the equipment to be charged and the vehicle-mounted wireless charging device can be established so as to wirelessly charge the equipment to be charged.
In the embodiment of the invention, a detection object for foreign matter detection is determined by acquiring the current state of vehicle-mounted wireless charging; detecting whether the detection object exists in a preset range or not; and when the detection result of the detection object is a preset result, executing alarm prompt. In the embodiment of the invention, the corresponding foreign matter detection strategy is executed by judging the current state of the vehicle-mounted wireless charging, so that the alarm prompt is executed only when the detection result is the preset result, and the alarm prompt can not be executed under other conditions, thereby avoiding frequent alarm caused by the existence of foreign matters in the wireless charging device in the standby state, reducing the energy consumption of the vehicle and improving the user experience.
In this embodiment, when the vehicle-mounted wireless charging apparatus is in a standby state and there is no device to be charged, even if there is a foreign object in the charging area of the vehicle-mounted wireless charging apparatus, the foreign object alarm is not generated. And only when the charging area of the vehicle-mounted wireless charging device has the equipment to be charged and the metal foreign bodies, the alarm prompt is executed. Therefore, frequent alarming caused by the existence of metal foreign matters when the vehicle-mounted wireless charging equipment is in a standby mode is avoided.
