Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
To make the objects, technical solutions and advantages of the present application more clear, the following description is made by way of specific embodiments with reference to the accompanying drawings.
The application scenario of the intelligent key authentication method provided by the embodiment of the application includes that the intelligent key and a lifting mechanism arranged in a vehicle. The lifting mechanism is used for placing the intelligent key and interacts with the intelligent key after the intelligent key is successfully authenticated. Intelligent key and elevating system can be fixed through magnetism the mode of inhaling, under the fixed state, intelligent key and elevating system are mutual through 4 metal contact structures, wherein two metal contacts are used for elevating system to charge for intelligent key, two other metal contacts are used for data communication between intelligent key and the elevating system, communication mode can adopt UART (Universal Asynchronous Receiver/Transmitter, general Asynchronous Receiver/Transmitter) serial port communication, communication content includes equipment authentication, vehicle condition data, key accuse car instruction etc..
The lifting mechanism can be arranged around a Head Unit System (HUT) in the vehicle or between two air conditioning ports in the middle of the center console. When the intelligent key is not placed, the lifting mechanism is in a lifting state, and the surface of the lifting mechanism is flush with the inner decoration of the whole vehicle. After placing intelligent key and the two completion communication authentication, elevating system drives the automatic decline of vehicle key, descends to the right place after, intelligent key surface and whole car interior trim parallel and level.
Referring to fig. 1, it shows a flowchart of an implementation of the smart key authentication method provided in the embodiment of the present application, and the method is detailed as follows:
in S101, when the smart key is connected to the elevating mechanism on the vehicle, the smart key transmits its own identification information to the elevating mechanism.
After the intelligent key is connected with the lifting mechanism on the vehicle, the intelligent key and the lifting mechanism need to be communicated for legality authentication, and at the moment, the intelligent key sends identification information of the intelligent key to the lifting mechanism. The identification information of the smart key can distinguish the smart key from other keys or other devices, and the smart key can be uniquely identified through the identification information.
In S102, if the lifting mechanism receives the identification information of the smart key for the first time within a first preset period, the lifting mechanism acquires the identification information of the vehicle, generating a first authentication request based on the identification information of the vehicle and the identification information of the smart key, and sending the first authentication request to a TSP (Telematics Service Provider); and the TSP carries out authentication based on the first authentication request, and if the authentication is successful, first authentication success information is sent to the lifting mechanism.
The duration of the first preset period may be set according to actual requirements, and may be, for example, one day, five days, ten days, one month, and the like, which is not limited herein.
The purpose of setting the first preset period is to: in a first preset period, if the intelligent key and the lifting mechanism are authenticated for the first time, authentication needs to be carried out through the TSP, and after the authentication for the first time is successful, the lifting mechanism can store identification information of the intelligent key, so that in the first preset period, when the intelligent key and the lifting mechanism are authenticated again, the authentication can be completed through the identification information of the intelligent key stored locally in the lifting mechanism, and the operation is convenient and fast. In order to enhance the safety of the vehicle system, when the next first preset period starts, the smart key and the lifting mechanism still need to be authenticated through the TSP when the smart key and the lifting mechanism are authenticated for the first time. The TSP can be a background system of the Internet of vehicles and is the core of the Internet of vehicles.
If the lifting mechanism receives the identification information of the intelligent key for the first time in the first preset period, the lifting mechanism can acquire the identification information of the vehicle through the gateway after receiving the identification information sent by the intelligent key, and generate a first authentication request according to the received identification information of the intelligent key and the acquired identification information of the vehicle. The first authentication request carries identification information of the smart key and identification information of the vehicle. The identification information of the vehicle can distinguish the vehicle from other vehicles and the like, and the vehicle can be uniquely identified through the identification information.
After generating the first authentication request, the lifting mechanism sends the first authentication request to the TSP, so that the TSP can perform authentication based on the first authentication request, if the authentication is successful, first authentication success information is generated, and the first authentication success information is sent to the lifting mechanism to prompt the lifting mechanism that the communication authentication between the lifting mechanism and the intelligent key is successful; if the authentication fails, first authentication failure information is generated and sent to the lifting mechanism to prompt the lifting mechanism that the communication authentication between the lifting mechanism and the intelligent key fails.
In S103, if the lifting mechanism does not receive the identification information of the smart key for the first time within the first preset period, the lifting mechanism compares the currently received identification information of the smart key with the identification information of the smart key stored therein, and if the currently received identification information of the smart key is consistent with the identification information of the smart key stored therein, it is determined that the communication authentication between the smart key and the lifting mechanism is successful.
In this embodiment, in a first preset period, if the lifting mechanism does not receive the identification information of the smart key for the first time, the lifting mechanism may compare the identification information sent by the smart key with the identification information of the smart key stored locally, if the identification information sent by the smart key is consistent with the identification information of the smart key, the authentication is successful, and if the identification information sent by the lifting mechanism is inconsistent with the identification information of the smart key, the authentication is failed.
Since the same vehicle may be bound with a plurality of smart keys, the number of pieces of identification information of the smart keys stored in the elevating mechanism may be plural. When the lifting mechanism compares the currently received identification information of the intelligent key with the identification information of the intelligent key stored by the lifting mechanism, if the currently received identification information of the intelligent key is consistent with one of the identification information of all the intelligent keys stored by the lifting mechanism, the authentication is successful, and if the currently received identification information of the intelligent key is inconsistent with the identification information of all the intelligent keys stored by the lifting mechanism, the authentication is failed.
In the embodiment, in a first preset period, after the first authentication between the intelligent key and the lifting mechanism is successful, when the authentication is performed again, the local authentication is directly performed through the lifting mechanism without performing the authentication through the remote TSP, so that the authentication speed can be increased; and every time the first preset period is passed, when the intelligent key and the lifting mechanism are authenticated, remote authentication needs to be carried out through the TSP, and the safety of the vehicle system can be improved.
After the communication authentication between the intelligent key and the lifting mechanism is successful, the intelligent key and the lifting mechanism can be communicated with each other to realize some linkage functions. For example, after the communication authentication between the intelligent key and the lifting mechanism is successful, the lifting mechanism can be controlled to descend, so that the lifting mechanism performs descending operation, and after the intelligent key and the lifting mechanism descend in place, the surface of the vehicle key is flush with the interior trim, so that the vehicle key is prevented from being mistakenly touched, and the reliable connection between the vehicle key and the lifting mechanism is ensured. After the communication authentication between the intelligent key and the lifting mechanism is successful, the screen of the vehicle can be linked through the lifting mechanism, so that the display screen of the intelligent key and the screen of the vehicle play linked animation, and the technological sense and the attractiveness are increased.
In the embodiment, after the smart key is connected with the lifting mechanism on the vehicle, the smart key sends identification information of the smart key to the lifting mechanism, the lifting mechanism receives the identification information of the smart key for the first time in a first preset period according to whether the identification information of the smart key is received by the lifting mechanism for the first time, communication authentication is performed in different modes, if the identification information of the smart key is received by the lifting mechanism for the first time in the first preset period, a first authentication request is generated and sent to the TSP, authentication is performed through the TSP, if the identification information of the smart key is not received by the lifting mechanism for the first time in the first preset period, the received identification information of the smart key is compared with the locally stored identification information of the smart key, so that the purpose of authentication can be achieved, communication authentication between the smart key and the lifting mechanism in the vehicle can be achieved, communication between the smart key and the lifting mechanism can be facilitated, and some linkage functions can be achieved.
In some embodiments, the S102 may further include:
if the lifting mechanism receives the identification information of the intelligent key for the first time in the first preset period, the lifting mechanism stores the identification information of the intelligent key which is successfully authenticated this time after receiving the first authentication success information.
After receiving the first authentication success information, the lifting mechanism confirms that the first authentication with the intelligent key is successful in a first preset period, stores the identification information of the intelligent key, and can also send the authentication success information to the intelligent key so that the intelligent key can display the authentication success information on a display screen of the intelligent key to prompt a user.
After receiving the first authentication failure information, the lifting mechanism confirms that the communication authentication between the lifting mechanism and the intelligent key fails, and sends the authentication failure information to the intelligent key, so that the intelligent key displays the authentication failure information on a display screen of the intelligent key to prompt a user.
In the embodiment, after the lifting mechanism is successfully communicated with the intelligent key for the first time in the first preset period, the identification information of the intelligent key successfully authenticated at this time is stored, so that when the lifting mechanism is communicated with the intelligent key again for authentication in the first preset period, authentication can be performed according to the locally stored information, and the authentication speed can be increased.
In some embodiments, the "TSP performs authentication based on the first authentication request in S102, and if the authentication is successful, sends the first authentication success information to the elevator mechanism", and may include:
and the TSP checks the first authentication request with the pre-stored verification information, if the first authentication request is in accordance with the pre-stored verification information, the TSP determines that the communication authentication between the intelligent key and the lifting mechanism is successful, and sends first authentication success information to the lifting mechanism.
The authentication information pre-stored in the TSP may include identification information of the vehicle and identification information of the smart key, which are bound to each other. The pre-stored verification information can be that when the vehicle is produced, in the matching process of the vehicle and the intelligent key, the production line data reading equipment binds the identification information of the vehicle and the identification information of the intelligent key and uploads the binding information to the production system server. And the production system server sends the identification information of the bound vehicle and the identification information of the intelligent key to the TSP. The TSP stores the received identification information of the bound vehicle and the identification information of the smart key as the pre-stored authentication information.
And when the first authentication request is verified to be consistent with the prestored verification information, the TSP generates first authentication success information and sends the first authentication success information to the lifting mechanism so as to prompt the lifting mechanism that the communication authentication between the lifting mechanism and the intelligent key is successful. And when the first authentication request is inconsistent with the pre-stored verification information in verification, the TSP generates first authentication failure information and sends the first authentication failure information to the lifting mechanism so as to prompt the lifting mechanism that the communication authentication between the lifting mechanism and the intelligent key fails.
In some embodiments of the present invention, the, the pre-stored verification information comprises pre-stored identification information of the intelligent key and pre-stored identification information of the vehicle;
the TSP checks the first authentication request and prestored verification information, and if the first authentication request is consistent with the prestored verification information, the TSP determines that the communication authentication between the intelligent key and the lifting mechanism is successful, and the method comprises the following steps:
and the TSP analyzes the first authentication request to obtain the identification information of the intelligent key carried by the first authentication request and the identification information of the vehicle carried by the first authentication request, and if the identification information of the intelligent key carried by the first authentication request is consistent with the pre-stored identification information of the intelligent key and the identification information of the vehicle carried by the first authentication request is consistent with the pre-stored identification information of the vehicle, the communication authentication between the intelligent key and the lifting mechanism is determined to be successful.
The pre-stored identification information of the intelligent key and the pre-stored identification information of the vehicle are in a binding relationship.
In this embodiment, the TSP may determine that the communication authentication between the smart key and the lifting mechanism is successful when the identification information of the smart key carried in the first authentication request is consistent with the identification information of the pre-stored smart key, and the identification information of the vehicle carried in the first authentication request is consistent with the identification information of the pre-stored vehicle; and when the identification information of the intelligent key carried by the first authentication request is inconsistent with the pre-stored identification information of the intelligent key, or the identification information of the vehicle carried by the first authentication request is inconsistent with the pre-stored identification information of the vehicle, determining that the communication authentication between the intelligent key and the lifting mechanism fails.
Since the identification information of the same vehicle may be bound to the identification information of a plurality of smart keys, the identification information of the smart key carried by the first authentication request is consistent with the identification information of the pre-stored smart key, and the method may include: the identification information of the smart key carried by the first authentication request is consistent with one of the prestored identification information of all the smart keys bound with the identification information of the vehicle. The inconsistency between the identification information of the smart key carried in the first authentication request and the identification information of the pre-stored smart key may include: the identification information of the intelligent key carried by the first authentication request is inconsistent with the pre-stored identification information of all intelligent keys bound with the identification information of the vehicle.
In some embodiments, sending the first authentication request to the TSP includes:
the lifting mechanism sends the first authentication request to a T-BOX (telematics BOX) of the vehicle;
the T-BOX sends the first authentication request to the TSP.
The T-BOX is used as a vehicle communication module and can be used as a communication tool between the lifting mechanism and the TSP for forwarding communication data between the lifting mechanism and the TSP.
In some embodiments, the identification information of the key fob includes a Media Access Control Address (MAC) of the key fob; the Identification information of the Vehicle includes a Vehicle Identification Number (VIN) of the Vehicle.
The MAC of the smart key is unique and fixed, so that the MAC can be used as identification information of the smart key. Since the VIN of the vehicle is unique and fixed, it can be used as the identification information of the vehicle.
In some embodiments, the smart key authentication method further comprises:
after the intelligent key is connected with the vehicle control mobile terminal, the intelligent key sends identification information of the intelligent key to the vehicle control mobile terminal;
if the vehicle control mobile terminal receives the identification information of the intelligent key for the first time in a second preset period, the vehicle control mobile terminal acquires the identification information of the vehicle bound by the vehicle control mobile terminal, generates a second authentication request based on the identification information of the vehicle bound by the vehicle control mobile terminal and the received identification information of the intelligent key, and sends the second authentication request to the TSP; the TSP carries out authentication based on the second authentication request, and if the authentication is successful, second authentication success information is sent to the vehicle control mobile terminal;
if the vehicle control mobile terminal does not receive the identification information of the intelligent key for the first time in the second preset period, the vehicle control mobile terminal compares the currently received identification information of the intelligent key with the identification information of the intelligent key stored by the vehicle control mobile terminal, and if the currently received identification information of the intelligent key is consistent with the identification information of the intelligent key stored by the vehicle control mobile terminal, the vehicle control mobile terminal determines that the communication authentication between the intelligent key and the vehicle control mobile terminal is successful.

In this embodiment, the smart key can authenticate and communicate with the lifting mechanism in the vehicle, and can also authenticate and communicate with the vehicle control mobile terminal provided with the APP associated with the vehicle, so that the vehicle is controlled by the vehicle control mobile terminal to realize some linkage functions.
The purpose of setting the second preset period is similar to that of setting the first preset period. The purpose of setting the second preset period is that in the second preset period, if the intelligent key and the vehicle control mobile terminal are authenticated for the first time, authentication needs to be performed through TSP, after the authentication for the first time is successful, identification information of the intelligent key can be stored in the vehicle control mobile terminal, so that in the second preset period, when the intelligent key and the vehicle control mobile terminal are authenticated again, the authentication can be completed directly through the identification information of the intelligent key locally stored in the vehicle control mobile terminal, and the operation is convenient and fast. In order to enhance the safety of the vehicle system, when the next second preset period starts, the smart key and the vehicle control mobile terminal still need to be authenticated through the TSP when the smart key and the vehicle control mobile terminal are authenticated for the first time.
The duration of the second preset period may be set according to actual requirements, for example, the duration may be one day, five days, ten days, one month, and the like, which is not limited herein. The duration, the starting time and the ending time of the second preset period and the first preset period can be the same or different.
In this embodiment, after the intelligent key is connected with the car accuse mobile terminal who installs car accuse APP, the intelligent key needs to communicate legitimacy with car accuse mobile terminal and certifies, and at this moment, the intelligent key sends the identification information of self to car accuse mobile terminal.
If the vehicle control mobile terminal receives the identification information of the intelligent key for the first time in the second preset period, the vehicle control mobile terminal can acquire the identification information of the vehicle bound by the login account of the installed vehicle control APP after receiving the identification information sent by the intelligent key, and generates a second authentication request according to the received identification information of the intelligent key and the acquired identification information of the vehicle. The second authentication request carries identification information of the smart key and identification information of the vehicle.
And after the vehicle control mobile terminal generates a second authentication request, the second authentication request is sent to the TSP so as to facilitate information verification of the TSP.
And when the second authentication request is in check consistency with the pre-stored verification information, the TSP generates second authentication success information and sends the second authentication success information to the vehicle control mobile terminal to prompt the vehicle control mobile terminal that the communication authentication between the TSP and the intelligent key is successful, wherein the second authentication success information can be displayed in the vehicle control APP. And when the second authentication request is inconsistent with the pre-stored verification information, the TSP generates second authentication failure information and sends the second authentication failure information to the vehicle control mobile terminal so as to prompt the vehicle control mobile terminal that the communication authentication between the TSP and the intelligent key fails, wherein the second authentication failure information can be displayed in the vehicle control APP.
The process of the TSP verifying the second authentication request and the pre-stored verification information is similar to the process of the first authentication request and the pre-stored verification information, and is not repeated.
After receiving the second authentication success information, the vehicle control mobile terminal confirms that the vehicle control mobile terminal and the intelligent key are successfully authenticated for the first time in a second preset period, stores the identification information of the intelligent key, and can also send the authentication success information to the intelligent key so that the intelligent key can display the authentication success information on a display screen of the intelligent key to prompt a user.
