An automatic transmission controller for a vehicle has an insufficient gear shifting time determining device that determines whether a gear shifting time for shifting performed by disengagement of two engaging elements and engagement of two engaging elements is insufficient; and a double engage/disengage prohibiting device that prohibits the gear shift after the disengagement of two engaging elements and engagement of two engaging elements when the insufficient shifting time determining device determines that the gear shifting time for shifting after the disengagement of two engaging elements and engagement of two engaging elements is insufficient.

A diagnostic system for an automatic transmission is provided in which a microcomputer determines that torque that can drive the driving wheels of the vehicle is not transmitted to an output shaft of the automatic transmission when the vehicle is stopped and the ignition key is operated to the OFF position, and performs forced energization of solenoids of solenoid valves associated with respective friction devices of the transmission, while monitoring current passing through the solenoid valves. If the current monitored does not match the current for energizing any of the solenoids, the microcomputer determines that the corresponding solenoid valve is at fault. Thus, the diagnostic system appropriately determines the presence of a fault of each solenoid valve for controlling the hydraulic pressure to each friction device, with increased flexibility and freedom.

When shifting an automatic transmission into a higher gear, it is determined that an inertia phase has started when an input rotation speed of the automatic transmission has started to decrease. Here, if throttle opening amount reduction control is being performed to reduce the output torque of the engine when it is determined that the inertia phase has started, it is highly likely that that determination is erroneous because that control causes the input rotation speed of the automatic transmission (i. e. , the engine speed) to decrease. When it is highly likely that the determination that the inertia phase has started is erroneous in this way, learning of a hydraulic pressure command value is prohibited. As a result, erroneous learning of the hydraulic pressure command value can be prevented.

A shift control device is provided with a structure wherein when a driver selects a manual shift mode, an appropriate shift level is set as an initial shift level in conformity to a driver's will to have or not to have a drive-force source braking effect. When a shift lever is operatively moved to an S-position to select an S-mode, depending on whether a stay time in a position “D” continuing for a certain time period or more (step S), a shift mode switching or a manual shift mode direct-selecting is determined, and then an initial shift level is individually determined for a shift mode switching (YES in step S) and a manual shift mode direct-selecting (NO in step S). This determines appropriate initial shift level in conformity to the driver's will to have the drive-force source braking effect in the shift mode switching and that not to have the drive-force source braking effect in the manual shift mode direct-selecting.

An ECU for a vehicle equipped with an automatic transmission includes a detection unit that detects a position of a transmission selection member manipulated by a driver; a determination unit that determines whether a gear step is abnormal when a preset time has elapsed after the transmission selection member is shifted from a drive position to a neutral position. The ECU further includes a control unit that controls the automatic transmission such that if the transmission selection member is shifted from the neutral position to the drive position when the gear step has been determined to be abnormal, a shock generated by the engagement of the frictional engagement elements is reduced.
