Vehicle Sub-Unit Features TRIZ Cases
- Bowed Shutter Grille Flow Control Assembly
Bowed shutters nest within curved grilles via gooseneck hinges, eliminating gaps that increase aerodynamic drag and reduce fuel efficiency.
- Vehicle Power Transfer Device Clutch Engagement Control
Electronic control unit executes gradual reduction control on motor rotation angle to lower average current while maintaining friction clutch engagement.
- Dissimilar Metal Joining via Intermediary Layer Welding
An intermediary metal layer welded through clearance openings prevents galvanic corrosion and simplifies manufacturing by standardizing weld schedules.
- Asymmetric Shift Cam Indexing for AMT Torque Reduction
An asymmetric index cam adjusts rotation angles to reduce torque requirements in automated manual transmissions.
- Differential Lock Control Reducing Wear via Speed Feedback
A differential lock control unit uses speed feedback to manage activation timing and prevent unnecessary cycling.
- Motor Output Control for Vehicle Turning Drivability
A motor control device limits differential torque between left and right electric motors to maintain vehicle turning performance.
- Adaptive Steering Wheel Torque Detection for Uneven Roads
A driver activity detection system adjusts torque thresholds based on road surface conditions to monitor steering wheel engagement accurately.
- AWD Driveline Sleeve for Locking Differential and Torque Distribution
Integrated sleeve mechanism merges disconnect and locking functions to minimize driveline losses while maintaining equal torque delivery.
- Filler Neck Housing Sealing and Mounting Arrangement
Segmented carrier simplifies mounting while elastic lips seal enlarged openings to prevent leakage.
- Drowsy Driving Detection via Eye Movement and Steering Torque Analysis
Processor detects slow eye movement and steering torque changes to identify driver drowsiness.
- Electric Brake System Hydraulic Control for Regenerative Braking Stability
Hydraulic control unit distributes braking force across wheels using segmented circuits, resolving instability from regenerative braking energy recovery.
- Motor Vehicle Body Structure Rear Shock Absorber Mounting
A motor vehicle body structure uses a raising part to connect the shock absorber cup to the reinforcing side member.
- Coolant Passage Connection Structure Tapered Water Deflection
Tapered connection member redirects water away from face seal members, preventing salt accumulation that corrodes casings and degrades seal integrity.
- Drivetrain Vent Relocation Tube Prevents Lubricant Expulsion
Relocating the vent intake prevents lubricant expulsion during operation, maintaining air pressure equalization across varying road grades.
- Variable Neutral Point Torque Control for Hybrid Vehicle Mode Transitions
A control system divides accelerator pedal strokes at a variable neutral point to manage regenerative braking torque setpoints based on vehicle speed.
