Example one
Fig. 1 is a flowchart of a vehicle message processing method according to an embodiment of the present invention, where the present embodiment is applicable to a situation of acquiring vehicle data, and the method may be executed by a vehicle message processing apparatus, where the vehicle message processing apparatus may be implemented in a form of hardware and/or software, and the vehicle message processing apparatus may be configured in a vehicle. As shown in fig. 1, the method includes:
s110, obtaining a configuration file, wherein the configuration file is used for configuring a data range and a storage format of the vehicle message to be analyzed.
The configuration file may be stored in a removable storage medium, and the removable storage medium in this embodiment may be a usb disk, which is not limited in this embodiment. The configuration file may include configuration information such as a communication type, a communication number, a filtering storage type, a message identifier list, and a communication Name, where the communication Name is used when the configuration file is stored.
In this embodiment, the mobile storage medium is connected to the vehicle-mounted gateway controller through a USB hardware interface, and as shown in fig. 2, the vehicle-mounted gateway controller is used as a terminal node for vehicle communication, and is responsible for connecting all controllers and networks on the entire vehicle and requiring transmission of communication information of the CAN/LIN/Eth network. The vehicle-mounted gateway controller is integrated with a saving component, and the component is used for detecting whether a specific cfg file exists in a mobile storage medium in real time; when a saving component operated by the gateway controller detects a configuration file, analyzing the cfg file; after the analysis is passed, the communication name ID data specified in the cancontrollllerreraanetwork, control area network/LIN (local interconnect network)/Eth (Ethernet) network corresponding to the entire vehicle message to be analyzed is stored according to the configuration file described by the cfg file, and the ID data is stored in the mobile storage medium according to a specific storage format.
The vehicle-mounted gateway controller in this embodiment is provided with a USB interface, and then completes storage and uploading of a vehicle message through a local or remote configuration mode by using an internet access function of a TBox (Telematics, car box). The configuration mode can be divided into two modes, one mode is that the configuration file is directly placed in the U disk through a local USB; another way is to download the configuration file remotely, and download the configuration file through the cloud. The data of the whole vehicle message can be configured to be acquired by a local USB flash disk and uploaded to a remote TSP (telematics service provider) platform. Through a local or remote configuration mode, the gateway controller can finish the storage and uploading of the message of the whole vehicle.
Specifically, when the gateway controller is in an offline state, a user may perform local configuration in a manner of placing a configuration file on the usb disk, where the local configuration includes the following specific steps: firstly, a user obtains a configuration file through a local PC (personal computer) end, secondly, the user can upload a corresponding vehicle encryption configuration file through a PC webpage end of a TSP (short message service) platform, the TSP platform encrypts the obtained configuration file and provides a download link, then, after the user obtains the encrypted configuration file, the configuration file is placed in a U (universal serial bus) packing directory and connected with a gateway controller, the gateway controller identifies that a U disk is inserted and reads a root directory file, decrypts the root directory file by adopting a private key of a certificate in the gateway controller, after the legality of the configuration file is confirmed, a message recording function is started, finally, in the message recording process, message data are temporarily stored in a flash of the gateway controller, after 128k (temporary) data are recorded, the data are transferred to the U disk, and the encryption is carried out through the private key of the certificate before the storage.

And issued to the gateway controller. 4. And after receiving the configuration file issued by the platform, the gateway controller decrypts by using a private key in a certificate in the gateway controller. And after the legality of the configuration file is confirmed, the message recording function is started to be executed. 5. In the process of recording the message, the message data is temporarily stored in a flash of a gateway controller, the data is transferred to a U disk after 128k (temporary) data is recorded, and the data is encrypted by a private key of a certificate before being stored.
Correspondingly, the steps of remotely acquiring data are as follows: and 1, the TSP platform issues a remote acquisition instruction. 2.

In this embodiment, the platform legitimacy authentication process of the certificate is performed after the gateway controller is started, and first, whether the certificate exists needs to be verified, if so, whether the certificate is consistent with the information of the frame number VIN and the gateway controller serial number SN of the actual vehicle is judged according to the information of the frame number VIN and the gateway controller serial number SN in the certificate, and if so, message data is encrypted through a private key in the certificate and is reported to the TSP platform through a TBox. And then, confirming whether the message comprises the vehicle frame number VIN, the SN number of the gateway controller and the random code 16Byte, if so, the legality authentication of the platform passes, decrypting the data by a public key reserved by the TSP platform, confirming whether the vehicle information and the information recorded in the background are correct and valid, identifying the gateway controller connected this time as a valid controller after confirmation, encrypting the 16Byte random code reported by the previous gateway controller by the public key, sending the encrypted 16Byte random code to the gateway controller to serve as a confirmation message of the TSP platform, finally, decrypting the received feedback information by the gateway controller by using a local private key, comparing whether the 16Byte random code is consistent with the previously sent random code, and if so, the gateway controller considers the platform to be legal and can carry out normal communication to obtain a configuration file.
