Technical Field

[0001] The present invention relates to the technical field of in-vehicle data communication, and particularly relates to a device and method for adjusting the vehicle-cloud communication address of remote diagnosis. Background Art

[0002] In the existing in-vehicle data communication technology, a separate communication interface is usually set up by the platform, and after the remote diagnosis command at the vehicle end is executed, the result is fed back to the platform through a preset platform address.

[0003] The existing in-vehicle data communication technology has poor flexibility. If the platform function is upgraded or the server is changed, resulting in the need to adjust the interface address, it is necessary to push updates to all vehicles in the market, and the change cost is too high. At the same time, the existing in-vehicle data communication technology has a single function and only supports public network communication or private network communication, making it difficult to achieve a quick switch between the public network and the private network.

[0004] Therefore, there is an expectation for a solution that can achieve a quick change of the platform communication address without updating the vehicle-end application, support a quick switch between the public network and private network communication methods between the vehicle and the cloud, and be compatible with the public network and private network communication of different vehicles.

[0065] The present invention will be described in more detail below through specific embodiments.

[0066] Embodiment 1

[0067] As Figure 1 shown, this embodiment provides a remote diagnostic vehicle cloud communication address adjustment device and a method performed in the device. The specific implementation process includes:

[0068] The technical solution of this embodiment is realized through the mutual cooperation of the remote diagnostic platform and the TBOX side. First, the vehicle cloud communication protocol is extended, and the platform communication interface address is sent to the vehicle side as part of the command. Secondly, two-way authentication is deployed between the vehicle side and the platform to avoid the vehicle or the platform server being attacked due to the leakage of the interface address;

[0069] The remote diagnostic platform mainly consists of a vehicle diagnostic page module, a command issuing module, a file management module, and an information security module; the vehicle diagnostic page module is mainly responsible for page buttons, and the user selects and inputs necessary information on the page according to his own diagnostic target;

[0070] After the user's operation is completed, the file management module determines whether the command executed by the user involves file transfer. When the security level of the executed task is relatively high and a security library file is required, or when the remote diagnostic platform needs to receive files uploaded from the TBOX, the file management module will give the remote diagnostic platform interface address to the command issuing module according to the task type and the public network and private network setting information of the remote diagnostic platform; in order to achieve the rapid switching of the public network and private network interface addresses, the file management module has deployed both a public network communication interface and a private network communication interface;

[0071] After receiving the user operation instruction and the interface address passed by the file management module, the command issuing module will edit this information into a command according to the vehicle cloud protocol and send it to the TBOX; since the vehicle TBOX versions in the market are not synchronized and the public network and private network interface addresses used by different vehicles are also different, the command issuing module will send both the private network address and the public network address, and at the same time attach a network selection flag bit. When the network selection flag bit = 1, the private network is used, and when the network selection flag bit = 0, the public network is used;

[0072] Finally, there is an information security module in the remote diagnosis platform. There is a risk of leakage when the interface address is passed to the vehicle terminal. Therefore, whether it is a public network address or a private network address, when the TBOX initiates a request to download the security library or a request to upload the TBOX log, it needs to pass the security authentication of the remote diagnosis platform before it is allowed to continue executing the task, so as to avoid maliciously calling the interface address to steal the security library file or transmit illegal information to the remote diagnosis platform;

[0073] On the TBOX side, it mainly involves a command receiving module, a command parsing module, a command execution module, a result returning module, and an information security module; due to the risk of interface address leakage, the command sender needs to pass the security authentication of the vehicle terminal before receiving the command, so as to avoid hackers forging diagnostic commands to attack the vehicle;

[0074] After the command receiving module receives the command, it hands it over to the command parsing module for parsing. For the old version of the TBOX, the TBOX can only parse out the public network address, and the remote diagnosis platform retains the public network interface address, so the function of the old version of the TBOX is not affected. For the new version of the TBOX, the TBOX can normally parse out the public network address, private network address, and network usage flag bit contained in the command, and provide the parsing result to the command execution module;

[0075] The command execution module will judge whether it is necessary to download the security library file according to the task type. Since the security library file involves the secure access of each controller and has a high confidentiality level, in order to reduce the risk of leaking the security library file through the TBOX, when the TBOX needs to use the security library file, it will call the public network / private network interface address to temporarily download the file according to the network usage flag bit, and immediately destroy it after the task is completed; for the task of log uploading type, it is the TBOX that calls the upload interface to transmit the log to the file management module; after the task is completed, the TBOX returns the execution result to the remote diagnosis platform, and the remote diagnosis platform displays the result on the page.

[0076] In the remote diagnosis vehicle-cloud communication address adjustment device in this embodiment, the platform communication interface address is sent to the TBOX side as part of the command, avoiding the update of the TBOX side when the interface address is changed. The TBOX side and the remote diagnosis platform have the ability of public network transmission and private network transmission, and can quickly switch between public network / private network communication methods. Both the TBOX side and the remote diagnosis platform will perform security authentication on the message source, and have high information security robustness.

[0077] The above has described the embodiments of the present invention. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
