Abstract:
1. A control apparatus for an automatic transmission in which a first frictional clutching element which is engaged at a first gear shift stage and which is released at a second gear shift stage is equipped, the control apparatus comprising: automatic transmission means for executing a gear shift to a gear shift stage automatically set on a basis of a traveling state; manual transmission means for executing the gear shift to the gear shift stage set through a manual operation; inertia phase determining means for determining a start of an inertia phase during the gear shift from the first gear shift stage to the second gear shift stage; and change mind gear shift determining means for inhibiting the gear shift from the second gear shift stage to the first gear shift stage and continuing the gear shift from the first gear shift stage to the second gear shift stage, when, during the gear shift from the first gear shift stage to the second gear shift stage, a request of the gear shift from the second gear shift stage to the first gear shift stage by means of the automatic transmission means has occurred during a time duration from a time at which a gear shift command from the first gear shift stage to the second gear shift stage is issued to a time at which the inertia phase is started and suspending the gear shift from the first gear shift stage to the second gear shift stage and allowing the gear shift from the second gear shift stage to the first gear shift stage, when, during the gear shift from the first gear shift stage to the second gear shift stage, another request of the gear shift from the second gear shift stage to the first gear shift stage by means of the manual transmission means has occurred during the time duration from a time at which the gear shift command from the first gear shift stage to the second gear shift stage is issued to a time at which the inertia phase is started.
