Retrofit DBW for Safe ADAS & Autonomous R&D.
Neyon is Gahan AI's family of retrofit Drive-By-Wire systems — steering, throttle, brake, and shifter — available in CAN-based and electromechanical configurations. CAN and ROS 2 interface, CARLA / DriveSim vehicle model integration, and HIL bench setup for a complete Sim → HIL → Road R&D pipeline.
Neyon in Action
Retrofit drive-by-wire in action — steering, throttle, and brake actuation on a real passenger vehicle platform.
CAN-Based vs Electromechanical
Two DBW configurations for different vehicle types and research requirements.
| Metric | CAN-Based DBW | Electromechanical DBW |
|---|---|---|
| Steering Actuation Latency | <50 ms | <100 ms |
| Braking Response | <50 ms | <100 ms |
| Throttle Latency | <50 ms | <100 ms |
| Steering Error | <1° | <2° |
| Brake Repeatability | ±1% | ±5% |
Two Variants. One DBW Stack.
From low-speed campus robotics to full L2+ public road R&D — Neyon scales to your platform.

Multi-Layer Safety Design
Neyon is designed for public-road ADAS R&D — every actuation channel has both hardware and software safety layers with graceful degradation.
Hardware Safety Layer
- Hardware E-Stop — physical stop on all channels
- Driver Override Detection — immediate handover to human
- Watchdog Timer — failsafe on comms loss
- Redundant Power Rails — actuation isolated from compute
Software Safety Layer
- Heartbeat Monitoring — ROS 2 / CAN node health checks
- Actuator Limits — configurable caps on all axes
- Fault State Machine — graceful degradation on failure
- Data Logging & Replay — full recording for post-analysis
Sim → HIL → Road
Develop in CARLA / DriveSim with the Neyon DBW vehicle model, validate on the HIL bench, then deploy on road. Reduces R&D risk at every stage.
