Drive by Wire Steering Kit: Precision Electronic Control for Modern Vehicles
Core Technology: Bidirectional Control Architecture
Position-Force Feedback System
Dual-Sensor Integration:
- Torque sensors (0.1N·m accuracy) capture driver input, while angle sensors (0.5° resolution) monitor steering wheel position.
- Current sensors optimize motor power delivery, ensuring 90% energy efficiency-critical for EV battery preservation.
Bidirectional Control Loop: Processes driver torque and vehicle speed data (via CAN bus) to generate real-time road feedback (e.g., tire grip, road texture) through the steering wheel module, maintaining natural driving feel.

System Modules: Engineered for Reliability
Steering Wheel Module
Haptic Feedback Design: Employs brushless motors to simulate road vibrations, with customizable feedback profiles (e.g., sport mode for enhanced resistance).
Redundant Sensors: Dual torque/angle sensors ensure 99.9% fault detection, critical for autonomous driving safety.
SBW System Controller
Real-Time Processing: 32-bit MCU processes 20+ sensor inputs within 50ms, adjusting steering assist based on vehicle dynamics (e.g., reducing assist at high speeds for stability).
CANopen Protocol: Seamlessly integrates with vehicle ECUs for data exchange (steering angle, assist torque).
Steering Execution Module
Direct-Actuator Design: Electric motors drive steering knuckles with 1500N·m peak torque, enabling 0.1° precision in wheel orientation-ideal for lane-keeping assist.
IP67 Protection: Dust-tight and water-resistant (1m submersion), reliable in all weather conditions.
