Abstract:
1. A control device of a vehicular automatic transmission, comprising: a neutral control unit that brings an engaging device provided in a power transmission path between an engine and driving wheels into a slipping state or a release state when a certain neutral control condition is satisfied while a shift lever is placed in a running position, so as to restrict power transmission through the power transmission path and reduce an idling load of the engine; a neutral-control cancellation control unit that engages the engaging device so as to increase a torque transmission capacity thereof when a certain neutral control cancellation condition is satisfied during neutral control under which the engaging device is in the slipping state or the release state; and an oil pressure holding unit that holds an engaging pressure of the engaging device at a constant pressure level for a given period of time, when an accelerator pedal is depressed while the engaging device is engaged so as to increase the torque transmission capacity thereof; wherein the given period of time for which the engaging pressure of the engaging device is held at the constant pressure level is a period starting at a point in time at which depression of the accelerator pedal is started.
