Steering Linkages TRIZ Cases
- Vehicle Steer-by-Wire Control for Stationary Wheel Return
A vehicle steering controller returns steered wheels toward straight ahead after zero speed, reducing tire wear and actuator loads.
- Electric Power Steering Control With Torque-Adaptive Friction Compensation
Torque-dependent friction compensation balances subtle steering feel with target-angle tracking during combined assist and angle control.
- Steer-By-Wire Actuator Control for Road-Rut Escape
When steering torque reaches a threshold, operator input cancels actuator output limits so wheels can escape road ruts without mechanical damage.
- Vehicle Lateral Motion Control with Dynamic Steering Limits
Rigid steering limits can hinder emergency maneuvering; dynamic thresholds use track deviation and vehicle state to stabilize lateral control.
- Steering Control Device With Gradual Torque Reduction for Stops
Gradually reducing steering and turning actuator torque before energization cutoff suppresses stop-related twisting and vibration.
- Steering Assistance Control with Road-Cant Torque Correction
Road surface cant and left-right steering differences are addressed with speed-cant maps that correct steering target torque.
- Rear Wheel Steering Controller for Power-Off Restarts
When a moving vehicle powers off, the controller commands the rear steering actuator to zero displacement for smooth restart behavior.
- Vehicle Yaw Control With Driver-Adaptive Steering Compensation
A yaw control unit detects vehicle speed, steering range, and input amount to compensate limited driver motion without hardware changes.
- Independent-Wheel Steering Mechanism Without Mechanical Linkage
Separate driving devices steer each wheel without a complex linkage, reducing steering-mechanism weight and space while supporting coordinated deflection.
- Steer-by-Wire Steering Synchronization by Deviation Range
Deviation-based synchronization aligns the steering wheel and turning wheels while limiting unnecessary rotation and driver discomfort.
- Steering System Resonance-Band Limiting Control
When steering-related frequency enters a resonance band, angle-limiting control helps prevent unstable vehicle behavior.
- Agricultural Automatic Steering Encoder Feedback for Manual Transfer
Encoder position and rate feedback detects manual steering intent without torque sensing, reducing false disengagements in agricultural vehicles.
- Steer-by-Wire Reaction Force Estimation for Quiet Tactile Feedback
A rack-force estimator switches simulated and bilateral motor control to filter road noise while preserving necessary steering feedback.
