Clutches TRIZ Cases
- Clutch Touch Point Detection via Drag Torque Correction
A clutch control module calculates drag torque from input shaft speed and acceleration to correct the touch point detection range.
- Dual-Clutch Transmission Hydraulic Control for Fast Shifting
Filling the second clutch hydraulic system to a touch point during preselection reduces shifting time while minimizing wear.
- Clutch Torque Profile for Smooth Engine Start
Strictly monotonically increasing clutch torque profiles eliminate dead time and abrupt torque buildup during internal combustion engine restarts.
- Clutch Torque Control for AMT Micro-Slip Transitions
PID controller resets clutch torque feedback when release is detected, preventing fuel-cut stops and reengagement collisions.
- Hybrid Vehicle Engine Starting Control via Clutch Slip
A hybrid vehicle engine starting system manages clutch slip to initiate combustion without driver disruption.
- Clutch Control Segmentation for Diesel Starting Noise
Dividing clutch control into low and full load speed ranges resolves aggressive torque spikes and noise during supercharged diesel engine starts.
- Hybrid Vehicle Power Transmission Device Friction Sliding Member
A hollow elastic sliding member generates frictional resistance between gear teeth to suppress vibration in hybrid vehicle power transmission systems.
- Vehicle Clutch Control Torque Prediction for Slippage Prevention
Controller estimates input torque changes from pedal position to adjust clutch actuator force, preventing slippage during sudden acceleration.
- Clutch Pedal Vibration Damping via Integrated Valve Piston
An integrated valve piston blocks oil passages without a separate stopper, eliminating ultrasonic welding complexity while maintaining sealability.
- Hydraulic Actuation Device for Multi-Clutch Transmissions
A hydraulic actuation device coordinates pump drive and proportional throttle valves to control clutch pressure circuits.
- Torque Converter One-Way Clutch Seizure Detection via Speed Ratio
A control system calculates the speed ratio between driving and output shafts to detect seized one-way clutch conditions in torque converters.
- Opposed High Pressure Hydraulic Brake System Thermal Management
Opposed hydraulic brake system raises fluid boiling point via above-atmospheric pressure and ceramic coatings, preventing vaporization under high heat.
- Vehicle Gear Change Control Device Torque Feedback
A gear change control device manages clutch engagement through real-time torque sensing.
- Clutch Torque Control for Slippery Road Starting
A clutch torque control system modifies accelerator sensitivity to manage power delivery during vehicle starts.
- Electromechanical Assembly Shaft Damping for Bearing Wear Reduction
Elastomer damping element inside female shaft exerts axial force on male shaft to preload rear bearing, reducing spline wear and noise from misalignment.
- Sealing Element for Wing Actuator Shafts
An integrated sealing element with lugs engaging shaft recesses simplifies assembly while ensuring reliable sealing against lubricants.
- Air Conditioning Compressor Clutch Slippage Control
Direct RPM monitoring prevents engine stall from torque overload while minimizing electrical energy consumption through dynamic clutch force adaptation.
- Differential Locking Clutch Control via Dynamic Current Reduction
A differential locking clutch control system reduces electric power delivery to the clutch motor after initial engagement.
