    摘要： In a system and method of controlling an automatic transmission that includes a lowest gear-stage friction element and has a lowest gear stage having a largest gear ratio and a gear stage other than the lowest gear stage, the lowest gear stage being established through engagement of the lowest gear-stage friction element, the gear stage other than the lowest gear stage being established while the lowest gear-stage friction element is kept in disengagement, a temperature of working oil in the automatic transmission is sensed, and use of the lowest gear stage is inhibited and use of the gear stage other than the lowest gear stage is allowed when the sensed temperature of the working oil is lower than a predetermined temperature as a predetermined extremely low temperature at which an engagement failure of the lowest gear-stage friction element is caused.

    摘要： There is provided a control apparatus for a vehicular automatic transmission which reliably inhibits switching between ranges caused by an erroneous operation of a shift lever and enables a vehicle to continue running normally without interfering with the operation of returning the shift lever to a normal position. When the shift lever is switched to a reverse range in a state in which a flag Flag_D_high indicative of a forward high vehicle speed assumes "1", this operation is determined as being an erroneous operation, and gear shift to a reverse gear position is inhibited from being accomplished. When the shift lever is switched to a forward range in a state in which a flag Flag_R_high indicative of a reverse high vehicle speed assumes "1", this operation is determined as being an erroneous operation, and gear shift to a forward gear position is inhibited from being accomplished. When the shift lever is returned to the previous range while accomplishment of gear shift to the reverse gear position or the forward gear position is inhibited, the inhibition is terminated to provide normal control, so that the vehicle can continue to run normally in the range suited to the driving condition before the erroneous operation.
