To provide a control device for a transmission system for a vehicle including an electrical differential part for controlling a differential state between the rotational speed of an input shaft coupled to an engine and the rotational speed of an output shaft by controlling the operating state of an electric motor and a transmission part that is arranged in a power transmission path between the electric differential part and a driving wheel, the control device preventing the rotational speed of the engine from reaching the high rotational speed of the engine when the transmission part performs shift.
This control device of a transmission system of a vehicle includes an engine upper limit setting means 86 for prelimiting an upper value NMAX of an engine rotational speed NE when the engine rotational speed NE is increased under torque-down control by a first motor M1 and a second motor M2 when an automatic transmission part 20 performs shift. Thus, it is possible to suppress an increase in the engine rotational speed NE, and to prevent the engine rotational speed NE from reaching the high rotational speed of the engine.
