AI Technical Summary
The existing vehicle electronic and electrical architecture has a complex wiring harness layout and excessively long wiring harnesses, making it difficult to achieve efficient end-to-end signal transmission and resulting in high communication latency, which cannot meet the real-time requirements of intelligent driving.
The closed-loop bus architecture connects the central integrated controller and gateway devices to the ring network, and transmits signals and power through a shared cable, reducing the number of wiring harnesses and the difficulty of laying out the system. The identification module and channel management module enable on-demand signal conditioning and fault detection, avoiding multiple protocol conversions.
It effectively reduces the length of wiring harnesses and the space occupied by the layout, reduces communication latency, improves the response speed and communication stability of controlled electrical devices, enhances fault resistance, and simplifies the network configuration process for electrical devices.
