and the elastic frame management component is used for receiving the elastic frame request, filtering the similar elastic frames and then performing elastic frame operation according to the current elastic frame state, wherein the elastic frame operation comprises the steps of hiding the current elastic frame, generating the elastic frame, loading the elastic frame and displaying the elastic frame.
3. The internet of vehicles module of claim 1, further comprising:
and the time synchronization component is used for controlling the time synchronization of each controller at the vehicle end by the time connected with the network.
4. A car networking access method using the car networking module of any one of claims 1-3, comprising:
the method comprises the steps of authenticating the Internet of vehicles service to obtain an access token corresponding to the Internet of vehicles service;
and after the localization of the access token is completed, performing parameter verification on the Internet of vehicles service request, adding the parameters passing the verification into the Internet of vehicles service request queue, waiting for request processing, and feeding back the request processing result to the requester.
5. The Internet of vehicles access method of claim 4, wherein authenticating the Internet of vehicles service to obtain the access token corresponding to the Internet of vehicles service comprises:
acquiring a client certificate, a root certificate and a client key, and exchanging certificates with a server where the Internet of vehicles service is located to complete authentication;
and after the authentication is passed, initializing a network access channel, and then accessing an access token providing interface in the Internet of vehicles service to obtain an authentication state and a corresponding Internet of vehicles service access token.
6. The internet of vehicles access method of claim 4, wherein the parameter verification of the internet of vehicles service request, the addition of the verified parameter to the internet of vehicles service request queue, the waiting for the request processing, and the feedback of the request processing result to the requesting party comprises:
the parameter of the Internet of vehicles request is checked, if the parameter passes the check, the parameter is standardized, the standardized parameter is added into an Internet of vehicles service request queue, and the request is waited to be processed;
and if the request processing fails, putting the request into the Internet of vehicles service request queue again, and waiting for the next processing until the request processing is successful.
7. A computer device, comprising: memory, processor and computer program stored on the memory and executable on the processor, characterized in that the processor implements the steps of the method of any of claims 4 to 6 when executing the computer program.
8. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the steps of the method of any one of claims 4 to 6.
