Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail each embodiment of the present invention with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

The embodiment of the application provides an unlocking circuit, which is applied to a vehicle. As shown in fig. 1, the unlocking circuit of the present embodiment includes a controller 110, a door lock device 120, and a plurality of elastic wave sensors 130, wherein the controller 110 is connected to the door lock device 120 and the plurality of elastic wave sensors 130, respectively. The elastic wave sensors 130 may be respectively disposed at different positions of the vehicle. In practical applications, the outer shell of the vehicle (including the door, window, front and rear covers, etc.) may be divided into a plurality of regions, and one elastic wave sensor 130 may be disposed in each region. In order to ensure the appearance, the plurality of elastic wave sensors 130 may be provided in different doors, and one elastic wave sensor 130 may be installed in each door. The elastic wave sensors 130 may be disposed in the vehicle door, the front door, and the rear door, which is not limited in this embodiment. The leads of elastic wave sensor 130 at various locations of the vehicle may be connected to controller 110 through wiring slots.

Each elastic wave sensor 130 is configured to acquire an elastic wave signal generated when the vehicle region is knocked by an external force, and output the elastic wave signal to the controller 110 for storage. The elastic wave sensor 130 includes, but is not limited to, a piezoelectric sensor, a strain sensor, and the like. The piezoelectric sensor may be a piezoelectric ceramic sensor, a piezoelectric film sensor, a piezoelectric crystal sensor, or other sensor having a piezoelectric effect. The controller 110 may be a vehicle-mounted controller, and after receiving the elastic wave signal, the controller may determine the external force striking position and the striking frequency corresponding to each striking position according to the elastic wave signal, and send an unlocking instruction to the door lock device 120 according to a comparison result between the striking position and the corresponding striking frequency and the preset door opening information. Specifically, the controller 110 may determine the knocking position of the external force according to the installation position of the elastic wave sensor corresponding to the received elastic wave signal, for example, if the elastic wave signal is transmitted to the controller 110 from the elastic wave sensor installed in the left rear door, it may be determined that the knocking position is at the left rear door. The controller 110 may also determine the knocking position according to the characteristics of the received elastic wave signal, and in this way, the characteristics of the elastic wave signal received by the controller 110 after each position is subjected to knocking can be learned through a machine in advance. After determining the tap positions, the controller 110 may determine the tap times corresponding to each position according to the number of times of the elastic wave signal transmitted by each position.

After determining the tapping positions and the tapping times corresponding to each tapping position, the controller 110 may compare the tapping positions and the tapping times with the preset door opening information. For example, the preset door opening information is that the left rear door is knocked twice, and the left front door is knocked once. The tap position determined by the controller 110 and the number of taps corresponding to each tap position are the same as the preset door opening information, and a door opening command is transmitted to the door lock position 120. It is worth mentioning that when performing the comparison, the sequence of the taps is also considered, for example, the tap sequence of the user is: the left front door is knocked once, the left rear door is knocked twice, although the knocking positions and the knocking times corresponding to each knocking position are the same as the preset door opening information, the knocking sequence is different from the preset door opening information, the knocking sequence and the preset door opening information are also considered to be different, and subsequent unlocking operation cannot be carried out.

As shown in fig. 2, the unlocking circuit may further include a first image collector 140, and the first image collector 140 is connected to the controller 110. Before sending the unlock instruction, the controller 110 may activate the first image collector 140 to obtain an image of a preset area of the vehicle to capture an image of a person currently knocking the vehicle, and compare the image with a preset user image to determine whether the person currently knocking the vehicle is a valid user of the vehicle. If the comparison result between the image and the preset user image is the same, and the determined knocking position and the corresponding knocking times are the same as the comparison result of the preset door opening information, the current vehicle knocking person is considered to be a legal vehicle user, and the controller 110 can send an unlocking instruction at this moment.

As an example, as shown in fig. 3, the unlocking circuit may further include a digital key controller 150, and the digital key controller 150 is connected to the controller 110. Before sending the unlock command, the controller 110 may start the digital key controller 150 to obtain the user identity credential from the target terminal, and send the identity credential to the first target device for identity authentication. If the identity authentication is passed and the comparison result of the determined knocking position and the corresponding knocking times is the same as the preset door opening information, the controller 110 can send an unlocking instruction at this time. The target terminal can be an intelligent terminal (digital key APP client) carried by a user, such as a mobile phone, a watch and the like. When the target terminal approaches the vehicle, both can establish a connection relationship, and the digital key controller 150 can directly obtain the user identity credential based on the connection. Preferably, the vehicle is connected to the target terminal through BLE, and the digital key controller 150 obtains the identity credential from the target terminal through BLE. The first target device may be a digital key cloud platform or a local server. It should be noted that the digital key controller 150 and the controller 110 may be physically independent, and the digital key controller 150 may also be a module of the controller 110, which is not limited in this embodiment.

For one embodiment, the unlocking circuit may further include a second image collector 160, and the second image collector 160 is connected to the controller 110. When the controller 110 sends the unlocking instruction, the second image collector 160 may be started to obtain an image in a preset area of the vehicle, and the image is sent to the second target device, so as to retain information of a door opener each time, and thus, the evidence obtaining is completed. The second target device 160 may be a digital key cloud platform and/or a digital key APP client. The digital key APP client is often an intelligent terminal carried by a user, such as a mobile phone, a watch, and the like.

The embodiment of the application also provides a vehicle, which comprises the unlocking circuit in the embodiment.

It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
