Abstract

Disclosed is a control device (10) for an automatic transmission installed in a vehicle capable of selecting a constant speed traveling mode, the control device comprising: a determination means (10B) that determines whether or not the vehicle is traveling on a ramp; a slope state-accommodating control means (10C) that, in cases where the vehicle is not traveling on a ramp, executes a first gear-shift control for selecting a predetermined gear shift stage in accordance with the vehicle state, and that, in cases where the vehicle is traveling on a ramp, executes a second gear-shift control for selecting, in accordance with the vehicle state, a lower gear shift stage compared to when the vehicle is not traveling on a ramp; a delaying means (10D) that, at the time of switching from the second gear-shift control to the first gear-shift control, shifts the gear up, stage by stage, at a predetermined time interval to a target gear shift stage; and a setting means (10E) that, when the vehicle is traveling in the constant speed traveling mode, makes the predetermined time interval shorter than when the vehicle is traveling in a mode other than the constant speed traveling mode.

Description

technical field [0001] The present invention relates to a control device for an automatic transmission equipped in a vehicle equipped with a constant speed travel mode. Background technique [0002] Patent Document 1 discloses a vehicle control device capable of realizing a first driving mode in which driving force control and automatic transmission shift control are performed based on driver's acceleration and deceleration operations, and setting a target running state (for example, a target vehicle speed). The second running mode (so-called constant speed running mode) in which driving force control and gear shift control are performed independently of the driver's acceleration and deceleration operations. In this control, in the second travel mode, by suppressing frequent execution of shifting, prevention of frequent shifting is realized. In addition, in the constant speed running mode, normally, when the vehicle speed deviates from a fixed vehicle speed range including ...
