METHOD AND SYSTEM FOR GENERATING AND USING VIRTUAL KEY OF VEHICLE

The invention relates to a method and system for generating and using a virtual key of a vehicle. The method comprises: presetting relevant keys and/or certificates in an onboard communication control module, a vehicle owner's terminal and a TSP; determining, by the TSP, whether a request of the vehicle owner's terminal for a virtual key is valid, and returning a URL of the virtual key to an authorization terminal if the request is valid, the authorization terminal invoking the virtual key from the TSP based on the URL of the virtual key; encrypting, by the authorization terminal, the virtual key, and sending the encrypted virtual key to the onboard communication control module; and reading, decrypting and verifying, by the onboard communication control module, the virtual key, and executing an instruction related to the virtual key when the verification succeeds. According to the invention, a vehicle owner can use a virtual key without relying on a network during an unlocking process, or authorize relatives and friends to use virtual keys and grant them certain permissions, or it is also possible for a TSP to authorize a service person to perform a permission-customizing operation within a specific time period.
