Abstract

The invention provides a shift control system of an automatic transmission, which is not set to a selected mode at a selection time point of setting to one of manual modes, but is set to the selected mode by a subsequent fixed operation. A shift control system (100) for an automatic transmission (300) capable of being set to an automatic shift mode or a manual shift mode according to the present invention has: a first manual mode in which a shift stage is switched and held by inputting a manual shift instruction using shift switches (42, 44); and a second manual mode in which the transmission mode is restored to the automatic transmission mode when a restoration condition is satisfied after the transmission stage is switched. The shift control system is provided with a mode selection module (56) for selecting and setting one of a first manual mode and a second manual mode in advance, and the mode selected in advance is changed from one of the first manual mode and the second manual mode to the other or from the other to one to set the automatic transmission to the automatic shift mode.

Description

technical field [0001] The invention relates to a speed change control system of an automatic transmission. Background technique [0002] Existing automatic transmissions can be set to a parking gear used when the vehicle is parked, a reverse gear used when the vehicle is reversed, a neutral gear used when the driving force is not transmitted to the vehicle, and a forward gear (automatic) that can automatically switch gears. shift mode). [0003] On the other hand, for example, in order to be able to start in second gear, it is required to manually switch the gear stage of the automatic transmission to travel. In order to meet this demand, for example, Patent Document 1 proposes a control device for an automatic transmission provided with a manual mode (manual transmission mode). When the control device of the automatic transmission is set to the manual mode, the shift stage can be upshifted or downshifted by, for example, a shift switch provided on the steering wheel. Th...
