Title:

AUTOMATIC TRANSMISSION CONTROL DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/125402

Kind Code:

A1

Abstract:

This automatic transmission control device, which is provided with a gear change control means (24) for downshifting by releasing a first frictional engagement element (H/C) that was engaged at a pre-gear change gear position, is provided with: an engine characteristic-determining means (FEA) for determining whether or not engine torque is in a prescribed region in which the change (∆T) in engine torque with respect to a change (∆APO) in accelerator pedal opening angle is smaller than other regions and the engine torque and engine rotation speed are within prescribed ranges; a driving state-determining means (FSA) for determining whether or not the accelerator pedal is in a prescribed operating state in which the accelerator pedal opening angle (APO) is at least a prescribed value (APOC) and the absolute value of the accelerator pedal opening rate (∆APO) is at or below a prescribed value (∆APO2); and a kick-down-prohibiting means (FKDP) for prohibiting downshifting when engine torque is determined to be within the prescribed region by the engine characteristic-determining means (FEA) and the accelerator pedal is determined to be in the prescribed operating state by the driving state-determining means (FSA).
