Central Domain Controller
The central computing unit of the vehicle E/E architecture
Overview
The Central Domain Controller (CDC) integrates engine management (EMS), transmission control (TCM) and vehicle control (VCU) into a single computing node for next-generation E/E architectures. Hanruijing builds it on a domestic multi-core automotive-grade MCU platform, covering powertrain domain through zonal control.
It supports CAN FD, automotive Ethernet and OTA updates on an AUTOSAR layered software stack, customizable to the OEM communication matrix and functional safety target up to ASIL-D.
Key Functions
Multi-domain integration
Converges powertrain, chassis and body functions to cut ECU count, harness length and vehicle weight.
Domestic multi-core MCU
Domestic automotive-grade multi-core MCU with headroom for complex control algorithms and multi-task scheduling.
High-speed in-vehicle network
CAN FD, LIN and automotive Ethernet with routing, gateway and UDS diagnostics.
OTA & cyber security
Secure boot, firmware signature verification and OTA updates for lifecycle iteration.
ASIL-D functional safety
ISO 26262 process with fault monitoring, safe-state transition and degraded operation.
Calibration & diagnostics loop
XCP/CCP calibration, UDS diagnostics and DTC management for OEM integration and aftersales.

Why It Wins
Lower vehicle BOM
Centralized architecture replaces distributed ECUs, reducing controller count and harness length.
Shorter development cycle
Reuse of proven software modules and calibration data significantly cuts re-development time.
Supply-chain autonomy
Domestic core chips and components eliminate import shortage and lead-time risk.
Volume-proven
The platform is in production on Dongfeng and VinFast programmes.
