One Controller, Six Core Functions — The Brain of Your Electric Vehicle
The Rawsuns 6-in-1 Vehicle Domain Controller (ICCU) is a highly integrated domain computing unit that consolidates Vehicle Control (VCU), Telematics Box (TBOX), EV Charging Controller (EVCC), Instrument Cluster (ICL), In-Vehicle Infotainment (IVI), and Thermal Management System (TMS) into a single, compact enclosure. Designed for next-generation electric vehicles, it eliminates distributed ECU complexity, reduces wiring harness cost, and delivers unified, intelligent control across the entire vehicle platform.
Six Core Functions at a Glance
| Module | Core Responsibility |
| VCU (Vehicle Control) | Torque coordination, drive mode management, signal acquisition (16× analog, 12× digital, PWM), powertrain state machine |
| TBOX (Telematics) | Remote monitoring, geofencing, stolen-vehicle tracking, OTA, 4G/GNSS communication |
| EVCC (Charging Control) | CCS2/GB-T charging protocol stack, charge session management, authentication & parameter negotiation |
| ICL (Instrument Cluster) | 7″ 1280×720 color LCD drive via LVDS+SerDes, tell-tale management, anti-tamper odometer |
| IVI (Infotainment) | Android OS on SoC, 10.1″ touch display, Bluetooth 5.0, Wi-Fi, multimedia, navigation |
| TMS (Thermal Management) | Multi-point NTC monitoring, intelligent fan PWM control, 3-tier thermal protection, cross-module coordination |
Why ICCU
- Radical Integration: Replaces 6+ distributed ECUs with a single domain controller — cuts wiring harness weight, reduces connectors, simplifies vehicle architecture.
- Dual-Chip Safety Architecture: Automotive-grade lockstep MCU (ASIL B/D) handles all safety-critical vehicle control; application SoC (D211DBV) runs Android/IVI at QM level. FFI-compliant isolation between safety and compute subsystems.
- Advanced Display Pipeline: LVDS 4-lane + SerDes (AIX915x/AIX916) transmission over FARKRA to 7″ 1000-lumen instrument display — long-distance, EMI-resistant, automotive-proven.
- Comprehensive Connectivity: 4× CAN FD (500k/250k), 1× LIN, 2× USB 2.0, 4G LTE, GNSS (multi-constellation), Wi-Fi 5, Bluetooth 5.0+, 2× CVBS camera input.
- Rich I/O Resources: 16× analog inputs (0–5V, incl. 90V HV sensing), 12× digital inputs, 2× PWM in/out, 8× high-side drivers (0.1–3A), 1× low-side, 2× H-bridge (charging lock), 2× analog out (0–10V/4–20mA).
- Intelligent Thermal Management: Real-time NTC monitoring across battery, motor, controller, cabin; adaptive fan speed control; 3-tier protection (normal/warning/protection); remote OTA optimization via TBOX.
- RPAS Reverse Assist: 4–8 ultrasonic sensors, 0.3–2.5m detection, visual+audio alerts, auto-activation below 10 km/h.
- Ruggedized Design: IP67/IP6K9K enclosure, aluminum alloy housing, −40°C to +85°C operation, 500h salt spray resistance, 5000m altitude, vibration/shock certified.
