Steering By Wire System

Core Design: Bidirectional Control for Natural Interaction

Dual-Module Architecture

Steering Wheel Force Feedback Module:

• Combines angle sensors (0.2° resolution), torque sensors (0.5N·m accuracy), and a road-feel motor to capture driver input and simulate real-world feedback (e.g., tire grip, road texture).
• Reducer mechanism ensures smooth force transmission, with a 5:1 gear ratio for precise response to small steering adjustments.

Steering Execution Module:

• Receives angle signals via CAN bus and drives wheel actuators with 0.1° positional accuracy, ensuring instant alignment with driver intent.
• Integrates current sensors to monitor motor load, critical for calculating road resistance and adjusting assist levels.

Position-Controlled Feedback Loop

Real-Time Synchronization: Compares steering wheel angle (driver input) with front-wheel angle (actual movement), correcting discrepancies within 50ms to maintain 99.5% tracking accuracy.

Speed-Adaptive Assist: Reduces assist torque at high speeds (≥80km/h) for stable lane keeping and increases it at low speeds (≤30km/h) for effortless parking-adapting to 80+ driving scenarios.

Enhanced Driving Experience

Customizable Road Feel: Luxury vehicles can offer 3+ feedback modes (comfort, sport, eco) via software tuning, adjusting resistance levels to match driver preferences.

Reduced Vibration: Advanced damping algorithms in the road-feel motor cut steering wheel vibrations by 40% compared to mechanical systems, improving comfort on rough roads.

Space & Energy Efficiency

30% More Cabin Space: Eliminates traditional steering columns and linkages, freeing room for EV battery placement or ergonomic interior designs.

50% Lower Power Consumption: Brushless motors in the execution module achieve 92% energy efficiency, extending EV range by up to 7% compared to hydraulic systems.

Safety-Ready Design

Dual Redundancy: Features backup sensors and power paths (ASIL-B compliant), ensuring 99.9% fault tolerance-critical for autonomous driving readiness.

IP67 Protection: Dust-tight and water-resistant (1m submersion), reliable in all weather conditions (e.g., heavy rain, dusty off-road trails).

Passenger Cars & High-Performance Models

Urban Commuters: Light assist (2–4N·m torque) reduces driver fatigue during stop-start traffic, with quick 2.5-turn lock-to-lock for tight maneuverability.

Sports Cars: Firm feedback (6–8N·m torque) in sport mode enhances cornering precision, translating road surface changes into intuitive steering responses.

Light Commercial Vehicles

Delivery Vans: High-torque execution (1500N·m peak) handles loaded turns effortlessly, while speed-sensitive assist improves stability at highway speeds.

Electric Buses: Modular design fits diverse chassis layouts, with CAN bus integration for seamless communication with vehicle control systems.

Rigorous Testing Protocols

10,000-Hour Endurance Test: Simulates 150,000km of driving to validate motor and sensor durability (98% failure-free rate).

Thermal & Vibration Tests: Operates reliably from -40°C to +85°C and withstands 50G vibrations, ideal for global climates.
