[0027] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0028] The present application provides a method for remote flashing of a vehicle controller. The method is implemented based on a remote flashing system for a vehicle controller and is mainly used to remotely flash the vehicle controller during testing at the vehicle development stage. The vehicle controller remote flashing system includes a server and a recorder. The server is connected to the recorder in communication. The recorder is configured on the vehicle side as a test tool and is connected to the vehicle controller in communication. The recorder is equipped with the UDS (Unified Diagnostic Services) protocol. Figure 1 The remote flashing method of the vehicle controller includes the following steps: S10: The server receives the original flash process file and the original file to be flashed uploaded by the user.
[0029] The file formats of the original flash process file and the original file to be flashed can be recognized and processed by the server. For example, the original flash process file can be a PROF file or a CAN flash process script. Correspondingly, the server is configured with INCA software that can use the PROF file, or VECTOR software that can use the CAN flash process script. The original file to be flashed can be a hex file, which can also be recognized and used by the server.
[0030] Exemplarily, the user may upload the pre-prepared original flashing process file and the original file to be flashed to the server through a user terminal connected to the server through communication.
[0031] S20: The server generates a flash configuration file and a file to be flashed that can be used by the recorder based on the original flash process file and the original file to be flashed. The flash configuration file records basic configuration information and flash control instructions for the flash.
[0032] For example, since the file formats of the original flash process file and the original file to be flashed cannot be directly recognized by the recorder, after receiving the original flash process file and the original file to be flashed, the server will respectively identify and process the original flash process file and the original file to be flashed, thereby obtaining a flash configuration file and a file to be flashed that can be used by the recorder. Among them, the flash configuration file records the basic configuration information of the flash and the flash control instructions.
[0033] Further, see Figure 2 , step S20 may include the following processing: S201: The server parses the original flash process file to obtain basic configuration information.
[0034] For example, the original flash process file uploaded by the user records the basic configuration information of the flash, such as CAN communication baud rate, host address, slave address, whether the CAN FD protocol (Controller Area Network Flexible Data Rate) is supported, etc. The server can obtain the above basic configuration information by parsing the original flash process file.
[0035] S202: The server generates a flash control instruction for the recorder based on the flash process defined in the original flash process file.
[0036] Exemplarily, the original flash process file also defines a flash process, and the server can identify the flash process and gradually translate it into flash control instructions for the recorder.
[0037] S203: The server generates a flash configuration file that can be used by the recorder.
[0038] Exemplarily, the server can generate a flash configuration file that can be used by the recorder based on the identified basic configuration information of the flash and the translated flash control instructions. For example, the flash configuration file can be a file in JSON format, which can be directly used by the recorder.
[0039] S204: The server converts the original file to be flashed into a file to be flashed that can be recognized by the recorder.
[0040] Exemplarily, the format of the original file to be flashed can be converted to obtain a file to be flashed that can be recognized by the recorder. For example, the format of the original file to be flashed can be a hex file, and the format of the file to be flashed obtained after the format conversion can be a bin file.
[0041] S30: The server sends the flash configuration file and the file to be flashed to the recorder.
[0042] Exemplarily, the server may send the generated flash configuration file and the file to be flashed to the recorder.
[0043] S40: The recorder flashes the vehicle controller based on the flash configuration file and the file to be flashed.
[0044] For example, after receiving the flash configuration file and the file to be flashed, the recorder will trigger the flash task for the connected vehicle controller. The recorder can write the file to be flashed into the vehicle controller by executing the flash control instruction, thus completing the flash of the vehicle controller.
[0045] Furthermore, during the execution of step S40, the recorder can also report the flashing status to the server in real time, such as flashing progress, flashing success, flashing failure, flashing interruption, etc. By checking the flashing status on the server, the engineer can perform corresponding processing in time.
[0046] Furthermore, in order to ensure data security, the process of flashing the vehicle controller based on the flashing configuration file and the file to be flashed by the recorder includes a security access service process. Figure 3 , the secure access service process includes the following steps: S401: The recorder sends a safety verification request to the vehicle controller.
[0047] Exemplarily, in the security access service process, the vehicle controller needs to be unlocked first, so the recorder sends a security verification request to the vehicle controller.
[0048] S402: After receiving the seed fed back by the vehicle controller, the recorder sends the seed to the server.
[0049] For example, after receiving the security verification request, the on-board controller will feedback a seed to the recorder, and the recorder will send the received seed to the server.
[0050] S403: The server parses the received seed and generates a key.
[0051] Exemplarily, the server stores a decryption file and is configured with a program that can call the decryption file. After receiving the seed, the server runs the program and calls the decryption file, thereby converting the seed into a key.
[0052] S404: The server sends the key to the recorder.
[0053] Exemplarily, the server may send the generated key to the recorder.
[0054] S405: The recorder unlocks the vehicle controller based on the key.
[0055] Exemplarily, the recorder unlocks the onboard controller based on the received key.
[0056] Furthermore, in order to reduce the possibility of the encryption algorithm being cracked, before the above step S404, the following processing is also included: The server encrypts the key.
[0057] Exemplarily, the server encrypts the key.
[0058] Furthermore, the encryption process mentioned above may be an asymmetric encryption process, and the server uses the public key to encrypt the generated key.
[0059] On this basis, in step S404, the key sent to the recorder is the encrypted key. At this time, step S405 in the above includes the following contents: The recorder decrypts the encrypted key.
[0060] Exemplarily, after receiving the encrypted key, the recorder can decrypt it. In the case where the encryption process is an asymmetric encryption process, the recorder can use the private key for decryption.
[0061] The recorder sends the decrypted key to the on-board controller to unlock the on-board controller.
[0062] Exemplarily, the recorder sends the decrypted key to the onboard controller to unlock the onboard controller.
[0063] Furthermore, in order to ensure the security of the flash configuration file and the file to be flashed sent by the server, the following processing may be further included before step S30: The server encrypts the flash configuration file and the file to be flashed.
[0064] In this case, before step S40, the following processing may also be included: The recorder decrypts the encrypted flash configuration file and the file to be flashed.
[0065] The embodiment of the present application provides a method for remote flashing of a vehicle controller. On the one hand, by uploading the original flashing process file and the original file to be flashed to the server, the server automatically parses the original flashing process file and the original file to be flashed, generates a flashing configuration file and a file to be flashed that can be used by the recorder, and sends them to the recorder, so that the recorder can directly use the flashing configuration file and the file to be flashed to complete the flashing of the vehicle controller, which solves the technical problem that the original flashing process file cannot be universal and requires manual secondary development of a new flashing process file, thereby improving efficiency. On the other hand, by placing the decryption file in the server, decrypting the seed in the server, and then sending the obtained key to the recorder, the problem that the decryption file cannot be shared on different platforms is solved.

[0075] Furthermore, the recorder is also used to send a security verification request to the vehicle controller during the process of flashing the vehicle controller based on the flashing configuration file and the file to be flashed, and after receiving the seed feedback from the vehicle controller, send the seed to the server.
[0076] The server also includes: The decryption module 530 is used to parse the received seed and generate a key.
