  The existing chassis electromechanical system architecture is not "safe" because each sub-function is sensed independently and control decisions are difficult to coordinate, so it is not "safe"; the electronic and electrical architecture is too redundant, and the manufacturing and matching costs are expensive, so it is difficult to talk about "efficient", for the pain point, Dr. Wei It is said that the significance of realizing the construction of the chassis domain control system lies in: realizing the integration and signal fusion of the chassis sensing system, the unified real-time solution of the dynamic vector observation and the differential equation system; Realize high-response model adjustment; the multi-objective chassis domain hierarchical coordination control mechanism based on intelligent game realizes balanced optimization and coordinated control of multiple execution systems; reduces the development and matching cost of the executive layer, and performs secondary verification on the intelligent driving domain to ensure Vehicle functional safety level and running quality.

  Talking about the architecture logic of the software and hardware of domain control technology, Dr. Wei said that the current logic of the software architecture is: sensor signal processing → driver intention recognition → finite state machine arbitration game, and the corresponding implementation methods are dynamic state observation, 15DOF Online solution, multi-objective optimization and coordinated control. The hardware architecture design should be considered from the design of the underlying security information flow, the upper-level security information flow design, the domain controller main control chip index, and the hierarchical architecture of the system security information flow. The specific solution implementation plan and rigorous technical logic have won the recognition of the audience in the field.

  When visiting the Yingchuang booth, which is full of friends, in the face of your friends' questions, Yu Miaoyu, the business manager of Yingchuang Huizhi, has been answering all kinds of questions for the visiting friends, and exchanged contact information with you, hoping to have more information with you. many exchanges.
