The Symbiosis – Why Drive-by-Wire and Autonomy Are Inseparable
Two Technologies. One Mission: Full Control Without the Driver.
Autonomous driving means: no human input. But how does a vehicle steer, brake, or accelerate without a human hand or foot?
The answer is simple yet radical: Drive-by-Wire is the foundational layer. Without it, autonomous vehicles would be paralyzed. Every decision – stop, swerve, accelerate – must be executed instantly, precisely, and safely.
The AD Stack Needs a Body
An autonomous vehicle consists of three core layers:
- Sensing – perceives the environment (camera, LiDAR, radar)
- AI & AD Stack – processes and decides
- Drive-by-Wire – executes the commands
Remove Layer 3 and everything else is just theory. The smartest algorithm means nothing without a reliable, safe path to the brakes or steering. It’s like a brain with no muscles.
Why Fail-Safe Isn’t Enough
Most legacy systems are fail-safe – they shut down when something goes wrong. Autonomous driving needs more: fail-operational.
- A backup instantly takes over if one ECU or sensor fails – no loss of control
- Communication is dual-redundant via separate channels
- Actuators are designed with isolated power supplies and redundancy
That’s exactly what NX NextMotion delivers – certified, validated, and field-proven.
Bottom Line: Only Drive-by-Wire Makes Autonomy Roadworthy
Whether it's measuring grip on black ice, swerving at 90 km/h, or braking precisely in urban traffic – only Drive-by-Wire can execute these maneuvers safely and legally.
NX NextMotion isn’t optional – it’s the cornerstone of true autonomous mobility.
Teleoperated driving combines state-of-the-art control technology with real-time communication. But how does it actually work? And what are the technical requirements?
