Gearing Control TRIZ Cases

By detecting shuttle motion and setting target braking force and pump or motor displacement, this case improves direction-switching response while suppressing shock.

Re-estimating shift phase timing during a gear-change transient shortens alternate shifts and reduces torque interruption.

Selecting a start gear from the target speed helps vehicles accelerate from standstill with fewer shifts, reducing power loss and improving response.

Display exposure and UI inputs shift with gear state and autonomous driving status to reduce gaze dispersion and improve input accuracy.

Conditional safe-state checking avoids abrupt power cuts, preserves operating data, and supports functional restart in drive train control.

Transmission sensor feedback detects early vibration and adjusts torque or gear ratio to suppress tractor power hopping.

Nonlinear torque allocation between offgoing and oncoming clutches suppresses shift torque surges and improves vehicle drivability.

An adjustable speed threshold lets work vehicles switch forward and reverse faster while limiting shocks and excess deceleration.

Buffer timing based on wheel acceleration and vehicle speed delays differential lock engagement to improve traction while reducing wear.

By integrating lost motion into the shift shaft, this case delays load transfer to the drive plate for smoother shifting and more flexible layout.

When the hydrostatic transmission fails, engine power is rerouted through the planetary gear path to keep drive wheels moving without major redesign.

A regulation portion constrains movable member tilt in an inhibitor switch, cutting contact sliding resistance and wear for better reliability.

Temporary service brake pressure is built and held during shift out of park to prevent roll on inclines and reduce parking brake wear.

A plunger pump and motor replace gear and friction drives to deliver stepless speed change, pivot steering, and longer axle service life.

A monitored dual control path verifies clutch and direction inputs before gear engagement to prevent sudden tractor starts.

An electromagnetic parking brake and neutral tow mode let a utility vehicle roll manually when low battery or failures block normal brake release.

Clutch control adjusts torque transfer as driveline play changes, reducing impact forces during acceleration and deceleration.

Return-line pressure is converted into hydraulic oil temperature through control valve behavior, cutting sensor count and maintenance.

Threshold-based clutch control adjusts for deceleration and switching time to engage hydraulic motors smoothly and cut audible torque.

A common tank line and check valve stabilize hydraulic pressure at both shift-rod ends to prevent mispositioning and improve shift quality.

By integrating the shift sensor with the shift shaft, this case detects gear input without a long shift rod, saving space in straddle-type vehicles.

Wear-adaptive speed regulation matches clutch and coupling tooth engagement, cutting clutch time while preserving coupling reliability and comfort.

A common tank line and shared valve unit stabilize hydraulic pressure, prevent air ingress, and keep selector rod gear positions precise.
