The further improvement lies in that: in the fourth step, the targeted message pushing and service comprises vehicle maintenance, upgrading, specific activity information, video and audio data preferred by the client and comprehensive column searching.
The further improvement lies in that: in the fifth step, the encrypted data A is bound with the VIN and the appkey of the vehicle.
The further improvement lies in that: in the sixth step, the TBOX system compares the generated encrypted data B with the transmitted encrypted data A, if the data are the same, the authenticity and the integrity of the data are determined, if the data are different, the data are tampered, and the tampering information is fed back to the manufacturer platform TSP for manual investigation.
The further improvement lies in that: and seventhly, displaying the single OTA upgrading information suggestion on a large screen of the vehicle-mounted audio-video host computer, and performing OTA upgrading on the audio-video host computer and other parts by selecting of a user.
The invention has the beneficial effects that: the invention utilizes the uniqueness of the VIN and the uniqueness of the appkey to establish an independent communication channel, collects the operation data of the vehicle and the user, utilizes big data analysis to obtain the information suitable for the maintenance, the upgrade and the specific activity of the vehicle, the information suitable for the audio-visual data of the client, the information of searching comprehensive column and the like, directionally pushes, can directionally push different information and services to different clients, improves the service experience of the client, saves the maintenance cost after sale, utilizes a 4G network to be wirelessly connected with a factory TSP platform, the 4G network is based on an SIM card, the SIM card is internally provided with a safety encryption chip, can encrypt the independent communication channel by inputting the key of the safety encryption chip in a key management main server, prevents the data from leaking, and can identify whether the data is falsified by comparing the pushed encryption data A and the received encryption data B, and is safer.
