1. A control apparatus of a vehicular drive system, comprising:
- an electric differential portion that has a differential mechanism which has a first element that is connected to an engine, a second element that is connected to a first electric motor, and a third element that is connected to a transmitting member, the differential mechanism distributing output from the engine to the first electric motor and the transmitting member;
a shifting portion that is provided in a power transmitting path between the transmitting member and a driving wheel;
a power storage device that supplies power which is used to drive the first electric motor or charges power which is generated by the first electric motor; and
a charging/discharging-restricted shift control apparatus that makes a determination to perform a shift in the shifting portion such that less power is charged to the power storage device or discharged from the power storage device when charging or discharging of the power storage device is restricted than when charging or discharging of the power storage device is not restricted, when a shift is performed in the shifting portion by controlling the rotation speed of the first electric motor.

Abstract
In a control apparatus of a vehicular drive system, a charging/discharging-restricted shift control apparatus makes a determination to perform a shift in a shifting portion such that less power is charged to a power storage device or discharged from a power storage device when charging or discharging of the power storage device is restricted than when charging or discharging of the power storage device is not restricted.

19. A control method for a vehicular drive system that includes i) an electric differential portion that has a differential mechanism which has a first element that is connected to an engine, a second element that is connected to a first electric motor, and a third element that is connected to a transmitting member, the differential mechanism distributing output from the engine to the first electric motor and the transmitting member, ii) a shifting portion that is provided in a power transmitting path between the transmitting member and a driving wheel, and iii) a power storage device that supplies power which is used to drive the first electric motor or charges power which is generated by the first electric motor, the control method comprising:
making a determination to perform a shift in the shifting portion such that less power is charged to the power storage device or discharged from the power storage device when charging or discharging of the power storage device is restricted than when charging or discharging of the power storage device is not restricted, when a shift is performed in the shifting portion by controlling the rotation speed of the first electric motor.
