Abstract
A control apparatus for a hybrid vehicle, having an engine, an electric motor, and an automatic transmission which is placed in a selected speed position with engagement of selected at least one of coupling devices, includes: an input torque control portion controlling the electric motor for controlling an input torque transmitted to the automatic transmission during a shifting action of the automatic transmission, based on output torque of the engine and torque transmitted through the coupling devices, such that a value representing a rotating state of an automatic transmission input rotary member coincides with a target value. The input torque control portion controls the input torque to be not smaller than a predetermined lower limit, when a running state of the hybrid vehicle is switched from a power-on state to a power-off state during a shift-down action of the automatic transmission in the power-on state.
