SBW Steering Correction for Driver Intent in Autonomous Driving

The patent introduces a correction device as an intermediary component that receives the road wheel actuator's output and adjusts it based on detected driver steering intent. This mediator bridges the gap between the autonomous system's road wheel control and the driver's steering wishes, allowing the SBW system to maintain its platform versatility while accurately reflecting driver intent through the correction mechanism.

The correction device applies partial correction only when necessary - specifically during autonomous driving mode when driver steering input is detected. The system maintains the simple follow-up operation for normal conditions but adds excessive correction capability when needed, applying the correction amount based on detected driver intent to achieve smooth operation with minimal additional complexity.

The patent implements a feedback mechanism where the correction device continuously monitors driver steering wheel operations during autonomous driving and uses this information to adjust the road wheel actuator's output. This feedback loop recovers the lost driver intent information that would normally be transmitted through mechanical connection, allowing the system to maintain layout flexibility while restoring the critical feedback pathway through electronic sensing and correction.
