Title: Torque control apparatus and control method for vehicle driving unit

Abstract: The prevention of the occurrence of a shock during acceleration is enabled without impairing acceleration response as to a control apparatus for a vehicle driving unit. By changing a control amount of a specific one or specific ones of the plurality of the control elements when a torque-up request is issued, the output torque of the vehicle driving unit is increased toward a target output torque. In this case, a torque gradient upon changing the control amount of the specific one or the specific ones of the control elements is estimated and calculated on the basis of a current output torque of the vehicle driving unit according to a calculation rule formulated in advance. The control amounts of the respective control elements including the specific one or the specific ones of the control elements are set such that the estimated torque gradient coincides with a predetermined target torque gradient.
