In an embodiment of the application, a data packet acquisition request is generated through the first vehicle-mounted terminal, and the acquisition request includes information of an un-downloaded data segment; the first vehicle-mounted terminal sends the acquisition request to the second vehicle-mounted terminal; the first vehicle-mounted terminal receives an un-downloaded data segment corresponding to the un-downloaded data segment information sent by the second vehicle-mounted terminal aiming at the acquisition request; the first vehicle-mounted terminal encapsulates the un-downloaded data segment and the downloaded data segment into a data packet, and the vehicle-mounted terminal is used as a data sharing node when the data packet is downloaded, so that the vehicle can obtain the data through other vehicle-mounted terminals in the process of downloading the data, wherein: data packages such as a vehicle-mounted terminal system software upgrading package and the like also improve the speed of the vehicle-mounted terminal in data downloading, reduce the flow cost of the vehicle-mounted terminal in data downloading during daily use, and improve the use experience of a user.
Next, the vehicle data sharing method in the present exemplary embodiment will be further described.
As described in the step S101, the first vehicle-mounted terminal generates a data packet obtaining request, where the obtaining request includes information of an un-downloaded data segment;
as an example, the first vehicle-mounted terminal generates information of an un-downloaded data segment according to a download progress, the download progress is a sequence number set of downloaded data segments, the first vehicle-mounted terminal screens out which data segments in a data packet have been downloaded according to the sequence number set, the part of the downloaded data segments is marked as downloaded data segments, the first server screens out the sequence number set of the data segments of the un-downloaded part in the data packet according to the sequence number set, generates information of the un-downloaded data segment according to the sequence number set of the un-downloaded data segment, and generates the acquisition request according to the information of the un-downloaded data segment.
It should be noted that the communication mode between the first vehicle-mounted terminal and the second vehicle-mounted terminal may be remote communication through a mobile network such as 4G, or may be short-range communication through WLAN or bluetooth, and generally is selected according to the distance between the vehicle-mounted terminals, where in the case of a short distance, a user may select to switch to the remote communication to obtain a data packet according to the actual communication situation;
as an example, when the distance between the vehicle-mounted terminals is 100 meters or more, the vehicle-mounted terminals are in long-distance communication, and at this time, the communication mode between the vehicle-mounted terminals can only be communication through a mobile network such as 4G and the like so as to perform data sharing; when the distance between the vehicle-mounted terminals is less than 100 meters, the short-distance communication is performed, wherein the short-distance communication is divided into two cases, when the distance between the vehicle-mounted terminals is 20-100 meters, the short-distance communication mode only supports the WLAN mode, and when the distance between the vehicle-mounted terminals is less than 20 meters, the short-distance communication mode simultaneously supports the WLAN and the Bluetooth.
In an embodiment, the mutual communication between the first vehicle-mounted terminal and the download server is also involved, and the step of generating the data packet obtaining request by the first vehicle-mounted terminal includes:
the first vehicle-mounted terminal initiates a search request to the download server, and the search request is used for searching the second vehicle-mounted terminal containing the un-downloaded data segment; the first vehicle-mounted terminal receives a search result fed back by the download server, wherein the search result comprises IP information of the second vehicle-mounted terminal; and the first vehicle-mounted terminal generates the acquisition request according to the IP information.
As an example, the download server is configured to send a data packet and IP information of the second vehicle-mounted terminal to the first vehicle-mounted terminal;
it should be noted that, when the download server sends the IP information of the second vehicle-mounted terminal, according to the distance between the second vehicle-mounted terminal and the first vehicle-mounted terminal, the second vehicle-mounted terminal and the first vehicle-mounted terminal support that kind of communication mode, but because there is an error relationship in the positioning information, there is a possibility that the actual distance between the second vehicle-mounted terminal and the first vehicle-mounted terminal is in the range supporting the short-distance communication mode, but the positioning distance exceeds the short-distance communication, after receiving the IP information of the second vehicle-mounted terminal, the first vehicle-mounted terminal obtains the information of the second vehicle-mounted terminal nearby through the WLAN module and the bluetooth module of the first vehicle-mounted terminal to perform position calibration of the second vehicle-mounted terminal, and further calibrate the communication mode between the second vehicle-mounted terminal and the first vehicle-mounted terminal.
As an example, after receiving the IP information of the second vehicle-mounted terminal fed back by the download server, the first vehicle-mounted terminal sends an inquiry signal through its WLAN module and bluetooth module to obtain the IP information of the vehicle-mounted terminal fed back by the vicinity inquiry, matches the IP information of the vehicle-mounted terminal with the IP information of the second vehicle-mounted terminal, and updates the communication support mode of the second vehicle-mounted terminal having the same IP information.
It should be noted that the data package may be an audio/video data package, a system upgrade package of the vehicle-mounted terminal, a navigation data package of the vehicle-mounted terminal, and an application software upgrade package deployed in the vehicle-mounted terminal,
the first vehicle-mounted terminal may correspond to a plurality of the second vehicle-mounted terminals, the second vehicle-mounted terminals corresponding to the first vehicle-mounted terminal are independent from each other, and the un-downloaded data segments contained in the second vehicle-mounted terminals corresponding to each of the first vehicle-mounted terminals are independent from each other;
as an example, the number of the second on-board terminals corresponding to the first on-board terminal a is two, and the second on-board terminal a1 and the second on-board terminal a2 are respectively the second on-board terminal a1 and the second on-board terminal a2, where the un-downloaded data segment a1 included in the second on-board terminal a1 and the un-downloaded data segment a2 included in the second on-board terminal a2 are independent of each other, the un-downloaded data segment a1 and the un-downloaded data segment a2 may be completely different, or the un-downloaded data segment a1 and the un-downloaded data segment a2 may mutually include a part of the same data, or the un-downloaded data segment a1 and the un-downloaded data segment a2 may be completely the same.
In an embodiment, the download server obtains the IP information of the second vehicle-mounted terminal by:
the download server acquires the download progress of the first vehicle-mounted terminal; the download server generates the un-downloaded data segment according to the download progress; and the download server matches the vehicle-mounted terminal containing the undelivered data segment according to the undelivered data segment.
As an example, the downloading progress may be that the first vehicle-mounted terminal downloads data segment information of the data packet; the download server obtains which data segments have been downloaded by the first vehicle-mounted terminal according to the download progress, the downloaded data segments of the part are downloaded data segments, the download server screens out the data segments of the part which is not downloaded in the data packet according to the obtained downloaded data segments, and the information of the un-downloaded data segments containing all or part of the data segments is generated according to the un-downloaded data segments of the part. The download server obtains the IP information of the vehicle-mounted terminal (namely, the second vehicle-mounted terminal) containing the un-downloaded data segment, wherein the second vehicle-mounted terminal can comprise the vehicle-mounted terminal containing all the un-downloaded data segment and/or the vehicle-mounted terminal containing part of the un-downloaded data segment.
In an embodiment, the method further comprises: the first vehicle-mounted terminal generates first interaction information for inquiring whether a user hides own IP information; the first vehicle-mounted terminal receives second interactive information fed back by a user; the first vehicle-mounted terminal judges whether the second interactive information is hidden; if yes, the first vehicle-mounted terminal hides own IP information and does not share the IP information to the download server; if not, the first vehicle-mounted terminal shares the IP information to the download server.
As an example, a user may set a vehicle-mounted terminal to be hidden or shared according to a need of the user, generally, when downloading a data packet for the first time, the vehicle-mounted terminal generates the first interaction information to inquire whether the user hides own IP information, and when setting for the first time, the user may select to keep a current selection result (hiding or sharing IP information) in a default state, or select to inquire each time downloading is performed; when the selection result is the default state, the user can modify the state of the vehicle-mounted terminal through setting. It should be noted that the operation of the user for modifying the state of the vehicle-mounted terminal is performed on the vehicle-mounted terminal in an information interaction manner, where the type of the interaction information may be a key, a touch screen, a gesture, or voice.
As described in the step S102, the first vehicle-mounted terminal sends the obtaining request to the second vehicle-mounted terminal;
it should be noted that the information of the un-downloaded data segment included in the acquisition request may be a sequence number of a data segment corresponding to the un-downloaded data segment.
As an example, the data packet may include 100 data segments, the sequence numbers of the data segments are sequentially 1 to 100, the information of the un-downloaded data segment included in the acquisition request may be a set of sequence numbers of the data segment corresponding to the un-downloaded part of the first vehicle-mounted terminal in the 100 data segments, it should be noted that, when the first vehicle-mounted terminal acquires the data segment of the data packet, it is not necessary to acquire the data segment sequentially according to the sequence number, and therefore, the sequence number of the un-downloaded data segment in the acquisition request may be a discontinuous data segment sequence number, such as: the data segment sequence numbers included in the get request include 20-25, and 35-45.
As described in step S103, the first vehicle-mounted terminal receives an un-downloaded data segment corresponding to the un-downloaded data segment information sent by the second vehicle-mounted terminal according to the obtaining request;
it should be noted that, the second vehicle-mounted terminal acquires the data segment with the same serial number as the part of the data segment in its own storage according to the serial number of the data segment in the acquisition request, generates the un-downloaded data segment from the part of the data segment, and sends the un-downloaded data segment to the first vehicle-mounted terminal, where the states (whether to share IP) of the vehicle-mounted terminals can be all vehicle-mounted terminals in the state of sharing IP information as the second vehicle-mounted terminal that sends the un-downloaded data segment.
It should be noted that, when the second vehicle-mounted terminal acquires the un-downloaded data segment, the first vehicle-mounted terminal may also acquire the un-downloaded data segment through the download server, and data acquisition between the two may be performed simultaneously without conflict.
As an example, there are 3 second vehicle-mounted terminals forming a data sharing connection with the first vehicle-mounted terminal B, which are respectively the second vehicle-mounted terminals B1, B2, and B3, wherein the data downloaded by the first vehicle-mounted terminal B includes 100 data segments, the serial numbers of the currently undelivered data segments include 20-30, 50-73, and 95-100, the second vehicle-mounted terminal B1 includes the data segment with the serial number of 20-45, the second vehicle-mounted terminal B2 includes the data segment with the serial number of 45-60, and the second vehicle-mounted terminal B3 includes a complete data packet, and when the second vehicle-mounted terminal B1, B2, and B3 receives the acquisition request sent by the first vehicle-mounted terminal B, the second vehicle-mounted terminal B1 generates the undelivered data segment with the serial number of 20-30 and sends the undelivered data segment to the first vehicle-mounted terminal B; the second vehicle-mounted terminal B2 generates an un-downloaded data segment with the serial number of 50-60 parts and sends the un-downloaded data segment to the first vehicle-mounted terminal B; the second vehicle-mounted terminal B3 generates un-downloaded data segments of the data segments with the serial numbers of 20-30, 50-73 and 95-100 and sends the un-downloaded data segments to the first vehicle-mounted terminal B; meanwhile, the first vehicle-mounted terminal B can also obtain data segments with the serial numbers of 20-30, 50-73 and 95-100 from the download server.
As described in step S104, the first vehicle-mounted terminal encapsulates the un-downloaded data segment and the downloaded data segment into a data packet.
In an embodiment, the method further comprises:
after the first vehicle-mounted terminal encapsulates the un-downloaded data segment and the downloaded data segment into a data packet, the first vehicle-mounted terminal extracts a target secret key in the data packet; the first vehicle-mounted terminal judges whether the data packet is safe or not according to the target secret key; and if so, upgrading the first vehicle-mounted terminal according to the data packet.
As an example, each vehicle-mounted terminal presets a key set for verifying the security of the downloaded data packet, and the key set may include 10 keys, where the keys are deployed with unique and non-repeating key numbers.
It should be noted that the step of presetting the key set to the vehicle-mounted terminal specifically includes: the download server verifies the vehicle identification number of the vehicle corresponding to the vehicle-mounted terminal, the safety certificate of the vehicle corresponding to the vehicle-mounted terminal and the cduld information of the vehicle corresponding to the vehicle-mounted terminal; the download server judges whether the check result is correct or not; if the vehicle identification number, the safety certificate and the cduld information are all the same as the preset information, the verification result is correct; when the judgment result that whether the verification result is correct is judged to be yes by the download server, the download server generates the key group request; the security server generates a specified number of secret keys and numbers the secret keys according to the generation sequence (secret key numbers); the security server generates a key set by the key and the key numbers of the specified number, stores the key set in a key database, and sends the key set to the download server; and finally, the download server feeds the secret key group back to the vehicle-mounted terminal.
It should be noted that the target key is a key obtained by the download server through the security server when the data packet is generated.
In an embodiment, the method further involves data interaction between the first vehicle-mounted terminal and a security server, and the step of extracting the target key in the data packet by the first vehicle-mounted terminal includes:
the first vehicle-mounted terminal extracts an identifier of a preset secret key in the data packet, wherein the preset secret key is generated for the security server; the first vehicle-mounted terminal matches a corresponding target secret key from the secret key group according to the identifier of the preset secret key; wherein the key set is generated for the secure server; the set of keys includes a predetermined number of keys.
As an example, the manner of generating the preset key by the secure server is specifically as follows: the security server searches out a key set from the key database, the key set is deployed with 10 keys, the security server randomly selects one key from the 10 keys as a preset key, sends the preset key and a key number corresponding to the preset key to the download server, and deploys the preset key and the key number into the data package through the download server.
In an embodiment, the step of determining, by the first vehicle-mounted terminal, whether the data packet is secure according to the target key includes:
the first vehicle-mounted terminal extracts first verification information in the data packet, wherein the first verification information is generated by the download server according to a preset algorithm and the preset secret key; the first vehicle-mounted terminal generates second verification information according to the preset algorithm and the target secret key; the first vehicle-mounted terminal judges whether the first verification information and the second verification information are the same; if so, the first vehicle-mounted terminal judges that the data packet is safe; and if not, the first vehicle-mounted terminal judges that the data packet is unsafe.
As an example, the preset algorithm may be a hash algorithm (SHA 256), the first verification information is a digest sgin1 generated by a preset key through the hash algorithm (SHA 256), the second verification information is a digest sgin2 generated by a hash algorithm (SHA 256) on a target key found from the vehicle-mounted terminal through a key number of the preset key, and when the digest sgin1 and the digest sgin2 are the same, that is, the data package is safe, the first vehicle-mounted terminal is upgraded according to the data package; when the abstract sgin1 is different from the abstract sgin2, namely the data packet is unsafe, the first vehicle-mounted terminal refuses to upgrade according to the data packet.
For the device embodiment, since it is basically similar to the method embodiment, the description is simple, and for the relevant points, refer to the partial description of the method embodiment.
