Abstract: To address the challenges of coordinating computing power and implementing real-time control in distributed driver assistance systems for commercial vehicles,this paper proposes a design solution based on a central domain controller.At the hardware level,the solution adopts a dual-chip collaborative architecture consisting of SoC and MCU.At the software level,it employs technologies such as hierarchical decoupling,dynamic service loading,and functional safety integration.Through this hardware-software co-design approach,the system achieves efficient resource utilization and overcomes communication bottlenecks,thereby providing a new technical pathway to address resource wastage and real-time constraints in distributed systems.
