Arnold NextG Blogspot | How Safety-by-Wire™ Secures Autonomous Driving

The PAVE Europe White Paper (2025) puts it clearly: “The key to public acceptance of autonomous vehicles lies in demonstrable safety – through testing, regulations, and robust safety design.”

Safety-by-Wire™ – Making Redundancy a Design Principle

With its NX NextMotion platform, Arnold NextG has created a vehicle control system built entirely for safety. At its core: fail-operational architecture – a system that continues to operate safely even when individual components fail.

Safety-by-Wire™ introduces a new class of safety-critical architecture with these core features:

• Multilayer redundancy: Steering, braking, and propulsion are independently and redundantly secured
• Intelligent signal logic: Only validated sensor input is accepted and executed
• Real-time fault isolation: Faulty components are immediately disconnected from the system
• Predictive fallback strategies: The system anticipates issues before they become safety-critical

The result: a control platform that’s not only safe – but provably safe under real-world conditions.

Trust Comes From Standards – Not Promises

Safety is measurable. That’s why NX NextMotion is aligned with the world’s most rigorous standards for functional safety and cybersecurity:

• ISO 26262 ASIL D – Maximum functional safety for automotive systems
• ISO 21434 & UNECE R155 – Certified cybersecurity and operational resilience
• FMVSS & ECE compliance – Designed for global homologation and deployment

These certifications aren’t marketing—they are engineering-level proof that this platform delivers on safety where it matters most.

One System, Multiple Components – Unified by Safety

The system overview reflects the full Safety-by-Wire™ concept in action:

• The NX NextMotion core unit at the heart of vehicle control
• A force feedback steering motor with integrated wheel, enabling precision tactile response
• A touch-based HMI display, optimized for safe driver interaction
• Certified wiring harnesses ensuring EMC and signal reliability
• A road wheel actuator that translates digital signals into millisecond-level mechanical control
• And in the background: three certificates validating the system’s global readiness

Together, these elements form a platform designed not just for autonomy – but for autonomy you can trust.

Conclusion: Safety Is Not a Feature – It’s the Starting Point

Autonomous mobility can only scale if its system architecture earns trust – technically, regulatorily, and societally. With Safety-by-Wire™, Arnold NextG delivers a fully validated, modular, and production-ready solution for safe driverless mobility.

Safety isn’t the goal. It’s the foundation.
