[0030] With the rapid development of electronic technology and the accelerated advancement and popularization of autonomous driving, the number of electrical components inside vehicles, the complexity of network communication, and the proportion of assisted driving and intelligent driving have all increased significantly. Existing distributed electrical architecture systems can no longer meet the current needs of in-vehicle electrical systems. Currently, mainstream vehicle propulsion domains, such as gateway control domains, can only serve as information interaction centers between in-vehicle sensors and actuators, resulting in low information security and an inability to solve the problems of information interaction between the inside and outside of the vehicle, as well as information interaction between high-computing units within the vehicle.

[0047] The interaction information generated by the interactive object and the vehicle of different communication types interacting with each other can be transmitted through each communication module of the same communication type in the external communication module 11. For example, the interactive object supports Bluetooth communication, and when the interactive object supporting Bluetooth communication interacts with the vehicle, the Bluetooth module 115 is used to transmit the interaction information. As can be seen, the external communication module 11 can be provided with each module of different communication types, so that the interactive object and the vehicle of different communication types can interact, and then the communication module of the corresponding communication type is used to transmit the interaction information to the core processing module 12.

[0068] In a possible design, the possible implementation manner of the core processing module performing external network isolation processing on the interaction information includes:

[0069] The core processing module first identifies and authenticates the received interaction information to establish a rule-based access control method. The rule-based access control method may, for example, only allow interaction information configured with a communication hardware device ID to access, and reject data access for non-configured IDs. Then, the interaction information is authorized with corresponding process operation permissions, and a secure memory running environment of the corresponding process is constructed, and a log system is used to record all operations of the external communication module for backtracking security attack behaviors, improving the security protection system, and achieving the purpose of external network isolation processing on the interaction information.

[0070] S103: The core processing module transmits the interaction information after external network isolation processing to the control unit through the processor communication module for vehicle control.

[0071] The core processing module performs external network isolation processing on the received interaction information, and then transmits the interaction information after external network isolation processing to the control unit through the processor communication module, so that the control unit performs vehicle control according to the received interaction information, and realizes the interaction of off-vehicle information.

[0072] In a possible design, before the core processing module transmits the interaction information after external network isolation processing to the control unit through the processor communication module, the method further includes:

Then the core processing module uses an encryption algorithm to isolate the confidentiality of the control information, stores redundantly, and ensures the integrity of the control information during end-to-end (E2E) transmission between control units. For example, the data protocol supported by the control information can contain fields CRC, timeout, counter, CRC cyclic redundancy check is used to check whether the control information transmission process is changed or transmission error; Timeout is used to control the time interval of the two messages before and after the calculation of the periodic message during the transmission of the control information between the control units, compared with the preset value, and then the communication state of the processor communication module is judged; counter provides sequence control of control information, which is used to detect out-of-order PDU or repeated PDU, such as data frames of the data link layer or data packets of the network layer, data segments of the transport layer, and higher layer data, etc. For control information, CRC (cyclic redundancy check) or other simple rules can be used for regular control information to improve the availability and efficiency of control information.

[0085] The internal network isolation processing of the core processing module can be performed on all control information communicated with the vehicle, and can also support identity authentication and encrypted transmission of both parties of the control information transmission.
