Abstract
A control apparatus for a vehicular drive apparatus including an engine and a motor is provided. The control apparatus includes a controller that determines the operating point of the engine and the operating point of the motor based on the characteristic of the vehicular drive apparatus. When at least one of the operating point of the motor and the operating point of the engine is in at least one of a motor noise occurrence region and a gear noise occurrence region, the controller changes the at least one of the operating point of the motor and the operating point of the engine so that the at least one of the operating point of the motor and the operating point of the engine avoids the at least one of the motor noise occurrence region and the gear noise occurrence region. This suppresses at least one of motor noise and gear noise.
