Mechanical Steering TRIZ Cases
- Mechanical Steering Wheel End Stops for Steer-by-Wire Tactile Feedback
Mechanical stops couple to the steering wheel shaft to restore tactile end feedback in steer-by-wire systems and support safer operation.
- Steer-by-Wire Road-Excitation Feedback Optimization
Steer-by-wire vehicles can lose distinct road feedback; measured tie-rod excitation is matched to a target progression to reduce vibration overlap.
- Steer-by-Wire Steering With Separate Redundant Sensor Links
Separate links carry redundant steering-angle data to the steering unit for plausibility checks, supporting functional safety with less control-unit complexity.
- Steering System Force Feedback With Dual-Phase Torque Switching
Dual phase systems switch force-feedback drive paths to prevent torque jumps, reduce component stress, and preserve steer-by-wire feedback.
- Steering Actuator Magnetic Sensing for Lower-Complexity SBW
Replacing LVDT sensing with a magnet and magnetic sensor simplifies steering-angle detection and reduces sensor size and unit cost in SBW.
- Steer-By-Wire Steering Redundancy for Failure Safety
Redundant sensors, actuators, and independent power paths maintain steering control when individual steer-by-wire components fail.
- Steering Control Unit Wake-Up Using Rotor Position Sensing
Rotor position sensing replaces noisy low-speed back-EMF monitoring to improve steering control unit wake-up reliability.
- Steering Input Stopper Geometry for Neutral Position Consistency
Asymmetric restriction geometry and nut alignment prevent mounting shifts, maintaining equal left and right limit tire steer angles.
- Steer-by-Wire Feedback Actuator Relocation Frees Steering Space
This steer-by-wire case uses external or bulkhead actuator mounting to preserve restoring torque while easing steering-column packaging.
- Steer-by-Wire Torque Modulation for Smaller Control Motors
Periodic torque modulation simulates stronger steering feedback with a smaller motor.
- Steering System Angle-Torque Feedback for Small-Range Precision
This case uses segmented angle ranges and different ratios to improve steering precision and driver feedback.
- Steer-by-Wire Mode Switching with Gradual Turning Current Control
A steer-by-wire controller gradually adjusts turning current during virtual-to-normal switching to prevent abnormal sounds and vibrations.
- Hydraulic Steering Control Paths for Fault-Tolerant Valve Actuation
Separate steering and switching paths use sensors and switches to prevent incorrect movements when control components fail.
- Handwheel Force Feedback Actuator With Variable Spring Preload
An electric motor and worm gear adjust spring preload for steer-by-wire feedback while reducing motor size and system cost.
- Steering Column Housing Segmentation for Differential Sealing
This steering column case uses segmented housings with higher control-unit sealing than sensor protection to balance reliability and cost.
- Steering Actuator Housing With Circumferential Recess for Flexible Coupling
A circumferential recess and adapted PCB support linear or rotational actuator movement in compact steering units.
- Steer-by-Wire Coupling Wear Detection Through Frequency Analysis
The control unit analyzes steering oscillation spectra to classify coupling wear and adapt parameters for accurate haptic feedback.
- Steer-by-Wire Dual Actuation for Fail-Safe Steering Forces
This steer-by-wire case uses parallel electric motors and hydraulic units to widen steering-force range and maintain fail-safe operation.
