S202: the internal communication module transmits control information to the core processing module.
The internal communication module is used for communication between sensors and/or actuators in the vehicle, and can transmit control information generated when the sensors and/or the actuators work to the core processing module.
S203: and the core processing module performs intranet isolation processing on the control information.
The core processing module performs intranet isolation processing on the received control information so as to protect the intranet network security of the vehicle and prevent the vehicle from being attacked by the intranet network.
In one possible design, the possible implementation manner of the intranet isolation processing of the control information by the core processing module includes:
the core processing module may first perform tag classification on the control information, for example, identify a GroupID corresponding to the control information, where the identified GroupID has internal IC communication, vehicle network communication, and so on, implement tag classification, and verify whether the tag of the control information is consistent with the control operation corresponding to the control information. And then the core processing module adopts an encryption algorithm to carry out confidentiality isolation on the control information so as to store the control information redundantly, and the integrity of the control information in end-to-end (E2E) transmission among the control units is ensured. For example, the data protocol supported by the control information may include a field CRC, timeout, counter, a CRC cyclic redundancy check for checking whether the control information transmission process is altered or transmission error; the Timeout is used for calculating the time interval of the two messages before and after the periodic message when the control information is transmitted between the control units, comparing the time interval with a preset value, and further judging the communication state of the processor communication module; the counter provides sequential control of control information for detecting out-of-order PDUs or repeatedly received PDUs, such as data frames of a data link layer or data packets of a network layer, data segments of a transport layer, and higher level data, etc. For control information, conventional control information may be performed using CRC (cyclic redundancy check) or other simple rules to improve usability and efficiency of control information.
The intranet isolation processing of the core processing module can be performed on all control information communicated with the interior of the vehicle, and can also support the identity authentication and encryption transmission of the control information transmission parties. For encryption transmission, the authentication mode among the nodes in the vehicle can be a symmetrical encryption mode, the adopted encryption algorithm can be AES128 or SM1/SM4, the identity authentication can be carried out through ciphertext communication of random numbers before the control information communication, and key control information can be communicated through the ciphertext.
In one possible design, an encryption module may be used to implement an encryption algorithm on the control information to ensure information security and improve the security of the vehicle information management system.
S204: the control information after the internal network isolation processing is transmitted to the control unit by the core processing module through the processor communication module, so that the control unit performs vehicle control.
The core processing module performs intranet isolation processing on the received control information, and then transmits the control information subjected to intranet isolation processing to the control unit through the processor communication module, so that the control unit performs vehicle control according to the received control information, and vehicle information interaction is realized.
According to the vehicle-mounted information management method, interaction is achieved through the internal communication module when each sensor and/or each actuator in the vehicle work, and control information is generated. The internal communication module transmits the control information to the core processing module, the core processing module performs intranet isolation processing on the received control information, and the control information after the intranet isolation processing is transmitted to the control unit through the processor communication module, so that the control unit performs vehicle control according to the control information.
