Gearing Control TRIZ Cases

A spring-pretensioned latch separates holding from readjustment, allowing reliable locking and temperature-driven release without coil energization.

Visual shift guidance recommends the correct pre-start gear in a bottom-neutral transmission, preventing unnecessary shifts that accelerate clutch wear.

Rotational position sensing times dog-clutch engagement to avoid tooth-on-tooth contact, reducing transmission wear and shift noise.

A timed override keeps the vehicle stop-hold function active when a cancel switch is held by external causes, preventing unintended creep.

The controller delays vehicle travel until the auxiliary power source can back up the main source, preventing steer-by-wire power loss.

Multiple eLSD torque requests are arbitrated to track yaw targets, limit wheel slip, and improve vehicle stability during critical events.

A learned environmental coefficient stabilizes electromagnetic valve control at engine startup while limiting valve and transmission operation.

Driving-force-based neutral switching time helps prevent erroneous shifts during travel while preserving fast response when cutoff is needed.

A non-linear feedforward model controls hydrostatic pump pressure and displacement for smoother torque-speed mode switching and lower latency.

Adaptive shift-point control uses battery and drive-state feedback to keep tractive force steady during powershift gear changes.
