Abstract:
PROBLEM TO BE SOLVED: To provide a control device of a vehicular automatic transmission capable of reducing slip-down of a vehicle, in down-shift after the vehicle is stopped on an uphill road.SOLUTION: In execution of down-shift during stop of a vehicle on an uphill road, compared to a case where the vehicle does not stop on the uphill road, by performing control to perform delivery of torque between engagement devices to be gripped alternately on a tie-up side, since force in a lock direction acts on a rotation member in an automatic transmission, slip-down of the vehicle can be suppressed.SELECTED DRAWING: Figure 3
