Preferably, the obtaining of the authentication key sent by the charging terminal may include:
receiving a key acquisition request sent by a wireless charging device;
and transmitting an authentication key to the wireless charging device in response to the key acquisition request.
In practical application, the key acquisition request can be displayed in a key input box of an APP page of the charging terminal, and the user can input the authentication key in the key input box and send the authentication key, so that the wireless charging device can acquire the authentication key.
Step S102, judging whether the authentication key is matched with a first preset key, if so, executing step S103.
And S103, wirelessly charging the charging terminal through a charging electromagnetic field generated by the wireless charging device, and simultaneously realizing communication between the charging terminal and the whole vehicle through a digital signal modulated in the charging electromagnetic field.
The permission corresponding to the first preset secret key can wirelessly charge the charging terminal, and can also realize communication between the charging terminal and the whole vehicle by means of the wireless charging device.
In the embodiment, the digital signal is modulated in the charging electromagnetic field for the wireless charging of the charging terminal by the wireless charging device, and the communication between the charging terminal and the whole vehicle can be realized while the wireless charging is carried out by the modulated digital signal. For example, during wireless charging, the wireless charging device sends an alternating electromagnetic field of 100-205 KHz to wirelessly charge the charging terminal, and simultaneously, 2KHz digital signals can be modulated in the electromagnetic field to realize communication between the charging terminal and the whole vehicle.
According to the technical scheme provided by the embodiment of the invention, when the relative position of the wireless charging device on the whole vehicle and the charging terminal meets the charging requirement, the authentication key sent by the charging terminal is obtained, when the authentication key is the first preset key, the charging terminal is charged wirelessly, and meanwhile, the communication between the charging terminal and the whole vehicle is realized through the wireless charging device. Therefore, the technical scheme provided by the embodiment not only realizes the charging function of the wireless charging device on the charging terminal, but also realizes the interactive communication between the charging terminal except for charging and the whole vehicle.
Referring to fig. 2, fig. 2 is a flowchart of another implementation of a communication interaction method between a charging terminal and a vehicle according to an embodiment of the present invention, where the method includes:
