摘要： A shift controller for an automatic transmission capable of automatically shifting up in a manual mode is provided. In the shift controller, a hysteresis between an automatic upshift line and a downshift permission line is set to be smaller as the accelerator opening degree decreases. As a result, when the accelerator opening degree is larger and therefore hunting is more likely to occur, it is possible to avoid an excessively small time interval between a downshift and an upshift. On the other hand, when the accelerator opening degree is smaller and therefore hunting is less likely to occur, a manual downshift permission region can be expanded to a higher rotational speed region, whereby a driver's manual downshift request can be satisfied in a higher vehicle speed region.

摘要： An automatic shift control is executed in an automatic transmission with 5 shift speeds of range hold type in the highest gear stage of a shift range at the manual shift mode. Upon selection of a shift mode from the automatic shift mode to the manual shift mode, the shift range at the manual shift mode is selected in accordance with the vehicle speed detected at the automatic shift mode. If the vehicle speed is in the low-speed range, the shift range 3 is selected. If the vehicle speed is in the medium-speed range, the shift range 4 is selected. If the vehicle speed is in the high-speed range, the shift range 5 is selected.

摘要： A control device for a vehicular automatic transmission which can realize a shifting with quickened response with suppressing a turbine blow-up during the shifting is provided. When a response in hydraulic pressure control by a hydraulic pressure control circuit 42 fails to satisfy a preset predetermined determining criterion, a shifting response is prevented from improving, in comparison to a case where the determining criterion is satisfied. Under a relatively low response of the hydraulic pressure control by the hydraulic pressure control circuit 42 due to air mixture to working oil, a control to inhibit a high-response shifting or the like is performed, so that a turbine blow-up caused by a delayed response of hydraulic pressure can be prevented. Thus, the control device for the vehicular automatic transmission can be provided, which can realize the shifting with quickened response, with suppressing the turbine blow-up during the shifting.

摘要： A control apparatus for a multi-speed automatic transmission which is equipped with a manual shift mode that allows a speed step to be shifted up or down manually by an operation of a driver of the vehicle is provided. The control apparatus permits a downshift to be manually performed, provided that during the manual mode, one of vehicle speed, engine rotation speed, and turbine rotation speed of the multi-speed automatic transmission is less than or equal to a downshift permission criterion value that is set according to the speed step achieved by the downshift. The control apparatus corrects the downshift permission criterion value by a speed-value-increasing correction amount that is computed according to the situation of travel of the vehicle. The control apparatus includes a speed-value-increasing correction amount computation portion that computes the speed-value-increasing correction amount separately for each of numbers of steps over which downshifts occur.
