Steering Linkages TRIZ Cases
- Parking Trajectory Planning Using Single-Wheel Rotation
Single-wheel rotation trajectory planning cuts gear shifts in narrow parking spaces by precomputing rotation start points and path segments.
- Steer-by-Wire Control for Lane Guidance and Haptic Steering Feedback
Independent steering wheel and wheel actuator control improves lane keeping while preserving driver haptic feedback in steer-by-wire vehicles.

- Six-Wheeled Active Caster Layout for Omni-Directional Stability
Active-caster middle wheels enable omni-directional travel while suspension improves balance, traction, and slip control on rough terrain.
- Rear Steering Recovery Control After Front Steering Failure
When front steering fails, rear-wheel steering rotates and redirects the vehicle to a safe destination with coordinated braking and drivetrain control.
- Rear-Wheel Steering Neutral Control for Sharp Steering Stability
Sensor-based rear-wheel steering switches to neutral control during sharp steering to avoid unstable mode changes and stabilize vehicle response.
- In-Wheel Steering Pulley Layout for Driven-Pulley Clearance
A dual-stage pulley layout creates more space above the driven pulley while keeping in-wheel steering compact and belt tension balanced.

A CFRP knuckle uses press-fit metal bushings, grooves, and bonding to cut weight while reinforcing ball-joint connection strength and durability.
- Vehicle Steering Control with Dynamic Modeling for Smooth Startup
Real-time vehicle modeling improves trajectory tracking under load changes while easing startup steering transitions for better driver comfort.
- Dual-Knuckle Suspension Structure for In-Wheel Motor Torque Steer
A rotation-restricted bushing and dual-knuckle layout curb kingpin offset and torque steer from in-wheel motors during driving and braking.
- In-Wheel Motor Suspension Layout for Large-Angle Steering
A pivot-mounted steering section removes tie rods to preserve cabin space, maintain wheel alignment, and enable zero-turn driving.
- In-Wheel Driving Module Layout for Limitless Steering Angle
A segmented steering and power layout enables 90°+ wheel angles, better durability, and compact packaging for full-flat vehicle mobility.
- Steering Reaction Force Control for Safer Lane Changes
Steering resistance is reduced during safe lane changes, but kept at standard force when a rear vehicle is approaching to lower contact risk.
- Steer-By-Wire Control Unit Partitioning for Lower-Cost Redundancy
Different-complexity control units split high- and low-level steering tasks to preserve steer-by-wire redundancy at lower cost.
- Hybrid Caster-Articulating Steering for Tight Turns on Turf
A single-lever hybrid steering layout blends caster and articulation to tighten turns, reduce turf damage, and improve hillside stability.
- Corner Module Architecture for Independent Wheel Control in EVs
A modular corner unit separates drive, steering, and suspension to cut transmission loss and improve independent wheel control in in-wheel EVs.
- Double-Wishbone Chassis Geometry for Brake Dive Resistance
Forward-inclined parallel control arm axes help a utility vehicle chassis resist brake dive and pitching while improving stability and steering return.
- Side-by-Side Vehicle Layout for a Lower Center of Gravity
Lower-mounted powertrain and lightweight frame materials reduce center of gravity, improving side-by-side vehicle stability on rugged terrain.
- Vehicle Ground Contact Load Estimation Using Acceleration Correction
Using acceleration-based correction, this case estimates vehicle ground contact load accurately while avoiding costly rolling and pitching sensors.
- Corner Module Bush Structure for 360-Degree Steering Vibration Isolation
Stacked upper and lower bushes with different hardnesses isolate steering vibration while preserving wheel rigidity for independent wheel steering.
- Integrated Vehicle Corner Module for In-Wheel Drive and Steering
An integrated corner module combines in-wheel drive, braking, suspension, and inclined-axis steering to cut power-transfer loss and packaging complexity.
- Steering Angle Estimation Using Yaw Acceleration and Rear Wheel Speeds
Rear wheel speeds, yaw rate, and Kalman-filtered yaw acceleration improve sensorless steering angle accuracy and response under slip.
- Rear-Wheel Steering Stick-Slip Detection and Limited Motor Control
Detects rear-wheel steering stick-slip from position and motor-current gaps, then limits motor operation to cut noise and shock.
- Joystick Steering Feedback Control for Four-Wheel Independent Steering
Sensors, PD/PI control, and a disturbance observer stabilize joystick steering by compensating lateral force and yaw effects.
- Steering Knuckle Layout for Higher Ground Clearance
By relocating the hub outside the control arm mounts, this knuckle raises ground clearance while preserving factory steering geometry and reducing wear.
- Cooperative Parking Control With RWS Failure-Adaptive Routing
RWS-aware parking control detects rear wheel steering failure, switches route strategy, and keeps remote parking efficient and usable.
- Steering Wheel Actuator Eddy Current Damping for Feedback Failure
Eddy current damping adds steering axle resistance when feedback fails, limiting abrupt steer-by-wire wheel input and stabilizing control.
- Vehicle Wind Compensation Control for Sustained Crosswinds and Gusts
Separating feedforward control for sustained crosswinds from feedback control for gusts helps maintain vehicle stability.
- Vehicle Steering Control Using Engine Speed Backup Signals
When ground speed data fails, engine speed and throttle input maintain steering assist and correct torque offset for more stable vehicle control.
- Steer-By-Wire Yaw Rate Control During Deceleration Turns
Adaptive gain control changes yaw rate response during deceleration and turning to improve steering easiness and accuracy in steer-by-wire vehicles.
