Sensor-based force feedback as an enabling technology for safe, real-time-capable steer-by-wire architectures at Level 5 autonomy.
Initial Situation: The Gap in Today’s Steer-by-Wire Systems
The automotive industry is rapidly advancing toward a future of fully autonomous driving. A core requirement for this is steer-by-wire technology—the complete decoupling of the steering wheel from mechanical linkages. But despite progress in sensors, AI, and control software, a critical piece is still missing: physical feedback.
Human drivers intuitively perceive subtle changes in road surface, grip levels, and traction. Autonomous systems, in contrast, lack this tactile perception. Many existing force feedback systems merely simulate resistance—without any reference to real-world road conditions.
Objective: Develop a Real-Time, Physical Force Feedback System
Arnold NextG set out to close this gap with the development of a force feedback system that:
At the heart of the solution is Arnold NextG’s patented force feedback technology. It converts real-time sensor data into actual steering forces, rather than simulating effects via algorithms.
Key features include:
Market Comparison: Where Other Systems Fall Short
Application Scenario: Autonomous Driving with Hidden Hazards
Use Case: Ice on a Bridge – Undetected by Cameras
A fully autonomous vehicle crosses a bridge in winter. Visual sensors detect no anomaly. The system calculates standard grip—until it begins to skid.
With Arnold NextG:
The Arnold NextG system is designed for seamless integration into OEM steer-by-wire environments. It offers:
Results: A New Benchmark in Intelligent Steering Feedback
Arnold NextG enables:
This case study proves: autonomous vehicles must physically sense their environment—not just simulate it. Arnold NextG bridges the gap between perception and action by delivering true tactile input for a new era of drive-by-wire mobility.

Objective: Develop a Real-Time, Physical Force Feedback System
Arnold NextG set out to close this gap with the development of a force feedback system that:
- Provides true, physical road feedback in real time
- Reacts dynamically and adaptively to road and vehicle conditions
- Is fully integrable into modern steer-by-wire platforms
- Enables the tactile intelligence required for safe autonomous driving at Level 5
At the heart of the solution is Arnold NextG’s patented force feedback technology. It converts real-time sensor data into actual steering forces, rather than simulating effects via algorithms.
Key features include:
- Sensor-based detection of surface structure, rolling resistance, and acceleration
- Direct physical feedback transmission to the steering actuator
- Adaptive steering feel based on environment, vehicle dynamics, and driver intent
- Full compliance with automotive safety standards including redundancy and fail-operational capability
Market Comparison: Where Other Systems Fall Short
- a) Electric Power Steering (e.g., Tesla, Bosch)
- Static feedback: No dynamic response to road changes
- Software-driven: No physical connection to the road
- b) Gaming Direct-Drive Systems
- Overdone, artificial effects
- Not suitable for real-world safety-critical automotive environments
- c) Software-Only Level-5 Concepts (e.g., Mobileye)
- No physical realism: Cameras and LiDAR see, but don’t feel
- Invisible hazards lead to dangerous assumptions
Application Scenario: Autonomous Driving with Hidden Hazards
Use Case: Ice on a Bridge – Undetected by Cameras
A fully autonomous vehicle crosses a bridge in winter. Visual sensors detect no anomaly. The system calculates standard grip—until it begins to skid.
With Arnold NextG:
- The system immediately detects grip loss via rolling resistance sensors
- Force feedback identifies the traction anomaly
- Steering and braking behavior are adjusted in real time
- The vehicle remains stable, the critical situation is avoided
The Arnold NextG system is designed for seamless integration into OEM steer-by-wire environments. It offers:
- Standardized API interfaces for backend integration
- CAN compatibility for vehicle networking
- Redundant architecture for safety-critical functionality
- Scalability for multiple vehicle classes
Results: A New Benchmark in Intelligent Steering Feedback
Arnold NextG enables:
- Realistic, adaptive steering behavior
- Safe autonomous operation in challenging road conditions
- Significant reduction in decision-making errors due to missing physical input
- Higher system reliability and overall safety performance
This case study proves: autonomous vehicles must physically sense their environment—not just simulate it. Arnold NextG bridges the gap between perception and action by delivering true tactile input for a new era of drive-by-wire mobility.
