Control Devices TRIZ Cases
- Automated Steering With Differential Braking for Stable Obstacle Evasion
A mixed controller coordinates steering and differential braking to evade obstacles quickly while keeping the vehicle controllable for smooth driver takeover.
- Hybrid Power Gauge Interface for Low-Burden Vehicle State Display
A unified hybrid power gauge combines electric and combustion power into one moving indicator to cut key presses and reduce driver cognitive load.
- Vehicle Speed Estimation Under Wheel Slip and Pitching
Switching acceleration limit modes during wheel slip improves estimated vehicle speed accuracy despite pitching-induced sensor deviation.
- Crosswalk-Aware Driving Assistance Zone Expansion for Early Detection
When a crosswalk is detected, the assistance zone expands outward to cover the full crossing and reduce pedestrian detection delay.
- Vehicle Following Control With Speed-Based Coasting Switch
Switching from distance control to speed control at higher lead-vehicle speeds cuts repeated coasting and powering changes to save energy.
- Hybrid Driving Architecture with Alignment Modules for Task Coordination
Alignment modules bridge human-defined and AI-defined interfaces to improve task coordination, interpretability, and update flexibility in automated driving.
- Autonomous Vehicle Shoulder Stop Zone Selection for Minimal Risk Maneuvers
When abnormalities occur in autonomous driving, the vehicle pre-identifies shoulder candidate zones and selects a minimal-risk stop position.
- Vehicle Risk Control for Narrow-Road Overtaking Scenarios
When an oncoming vehicle may pass a slow mover on a narrow road, control thresholds are relaxed to trigger earlier braking and cut contact risk.
- Automated Driving Activation via Adaptive Assistance Thresholds
Adaptive assistance thresholds and intervention tuning help establish automated driving conditions with less driver distraction and smoother autonomy handoff.
- Automated Vehicle Behavior Mode Control Under Module Failures
Predefined behavior modes let an automated vehicle switch around failed modules and keep control within safe boundary conditions.
- Launch Torque Reduction Control for Consistent Gear Shifts
Driver-set torque reduction is executed automatically during gear shifts to cut wheel slip and improve launch repeatability.
- Vehicle Side-Velocity Control for Low-Speed MPC Accuracy
Using left and right side velocity data, this case improves low-speed vehicle MPC accuracy and steering precision without relying on overall vehicle speed.
- In-Vehicle Commute Classification for Vehicle Type and User Role
Motion, driving pattern, and cabin sound data are fused with ML models to identify vehicle type and user role for continuous driving monitoring.
- Steering Wheel Paddle Control for Dynamic Shift and Speed Modes
A mode-selectable paddle switch lets the ECU switch between shift and speed control, reducing driver workload when road conditions change.
- Dual Automated Driving Control Switching After False End Commands
Redundant automated driving control waits before handover to manual mode, allowing fault-based switching and avoiding premature control loss.
- Vehicle Control Arbitration for Smooth Actuator Response
By restricting feedback control when actuators cannot respond, this vehicle controller avoids abrupt acceleration changes and preserves ride comfort.
- Autonomous Vehicle Trajectory Validation With Learned Divergence Metrics
Machine-learned divergence weighting helps autonomous vehicle trajectory validation separate material from immaterial deviations at scale.
- Engine Speed Slip Target Control for Split-Friction Differentials
Wheel speed feedback lowers the engine slip target under split-friction conditions to balance driven wheels and preserve tractive force.
- Vehicle Control Handover Based on Driver Skill and Road Difficulty
Transfers driving authority only when road conditions and driver skill indicate a smoother manual takeover with lower risk of abrupt braking or turning.
- Vehicle Longitudinal Motion Arbitration for Unified Request Control
A centralized arbitration and profile generation layer unifies multi-feature motion requests to cut duplicate torque conversions and improve drive quality.
- Blind-Spot Collision Warning Using Lateral TTC Prediction
Lateral warning zones, heading-angle checks, and TTC thresholds help detect blind-spot targets crossing into the ego-vehicle path.
- Vehicular Radar-Camera Lane Prediction During Camera Dropout
Radar road-edge sensing predicts lane position when camera markings disappear, helping maintain accurate vehicle control.
- Lens Shading Correction Using Radial and Non-Radial Calibration
A two-stage radial and Bezier-based non-radial correction flow flattens residual shading and improves wide-angle image stitching.
