Arrangement for controlling a driving engine when changing,to a higher gear,a step-change gearbox located downstream in the force path

摘要

An arrangement and method for controlling a driving engine-in the sense of reducing the torque when changing, to a higher gear, a step-change gearbox located downstream in the force path,-generates a gear-change recognition signal for the recognition of the gear-changing procedure and determining the beginning of the reduction exclusively by analysis of the variation of the engine rotational speed suppresses that signal on the appearance of rotational speed variations not caused by gear changing.
