AI Technical Summary

Technical Problem

Existing automotive control systems face communication delays and safety risks due to reliance on central computing platforms (CCP) or direct connections to CCPs, which can compromise vehicle safety in case of failures.

Method used

A vehicle control system with a central controller connected directly to vehicle components within different functional domains via dedicated networks, allowing for unified and coordinated control, reduced communication delays, and enabling components to share information and perform backup functions in case of central controller failure.

Benefits of technology

This system reduces communication delays, enhances safety by ensuring basic vehicle functions are maintained even in central controller failures, and lowers system costs by minimizing harness length and redundant communication.
