METHOD OF CONTROL OF GEARBOX Russian patent published in 2014 - IPC F16H61/02 F16H59/44 F16H59/48

Abstract RU 2514623 C2

FIELD: transport.

SUBSTANCE: set of inventions relates to automotive gearbox control and to carrier. Proposed method consists in changing from 1^st gear whereat carrier acceleration is negative to 2^nd gear whereat carrier acceleration is positive or zero. Downshift comprises gearshift mid stage between 1^st and 2^nd gears. Engine maximum rpm at every mid stage exceeds maximum engine rpm at previous gearshift mid stage. Proposed system comprises control unit. Control unit allows fulfilling the jobs of above described method. Transport facility incorporates above described system.

EFFECT: decreased fuel consumption and gearshift strokes.
