Abstract:
A control apparatus for a vehicular power transmitting system including an electrically controlled differential portion having an electric motor, and an automatic transmission portion, the control apparatus including shift control portion operable upon determination that a jump shift-down action of the automatic transmission portion directly to a target gear position while skipping at least one intermediate gear position should take place and upon inhibition of the jump shift-down action, to generate a shifting command to perform the jump shift-down action when total jump-shift-down-action time required for the jump shift-down action is shorter than total sequential-shift-down-operation time required for a sequential shift-down operation consisting of a shift-down action to each intermediate gear position and a shift-down action from the last intermediate gear position to the target gear position, and a shifting command to perform the sequential shift-down operation when the total jump-shift-down-action time is not shorter than the total sequential-shift-down-operation time.
