AUTOMATED TRANSMISSION CONTROL OPTIMISATION, SPECIFICALLY FOR TRUCK AUTOMATED TRANSMISSION Russian patent published in 2015 - IPC F16H59/14 F16H61/02 

Abstract RU 2539614 C2

FIELD: transport.

SUBSTANCE: invention relates to automated transmission control method intended specifically for truck automated transmission which is connected with driving engine in which method data and/or signals are transmitted to automated transmission controller by means of interface. When pre-specified event occurs time-predicted unstable profile of driving engine torque for this event is transmitted to automated transmission controller. Automated transmission controller sets and/or determines gear shift strategy based on this transmitted data. In order to control gear shifting operations and/or to prevent erratic operation of gearing the transmission controller determines based on transmitted driving engine torque profile whether gear shifting operation should be initiated or not, specifically if current torque is sufficient to initiate shifting operation to achieve required engine behaviour.

EFFECT: invention is aimed to simplify and improve the method.
