Vehicular drive control apparatus and control method of vehicular drive system

A vehicular drive control apparatus comprising:

• an electric differential portion that functions as an electric differential device and which has i) a differential mechanism that distributes output from an engine to a first electric motor and a transmitting member, and ii) a second electric motor that is connected to the transmitting member,
• a shifting portion that constitutes a portion of a power transmitting path from the transmitting member to the driving wheel;
• an apply device that is provided in the shifting portion and selectively transmits drive torque of the transmitting member to an input rotating member of the shifting portion;
• a shift operation executing device which is shifted between a non-drive position or non-drive range that places the power transmitting path in a power transmission-interrupted state and a drive position or drive range that places the power transmitting path in a power transmittable state;
• and
• a transmitting member rotation speed controlling portion which, when the shift operation executing device is shifted from the non-drive position or non-drive range into the drive position or drive range, controls the rotation speed of the transmitting member such that a predetermined rotation speed difference or predetermined rotation speed ratio is obtained between the rotation speed of the transmitting member and the rotation speed of the input rotating member of the shifting portion.

A control method of a vehicular drive system that includes an electric differential portion that functions as an electric differential device and which has i) a differential mechanism that distributes output from an engine to a first electric motor and a transmitting member, and ii) a second electric motor that is connected to the transmitting member;

• a shifting portion that functions as an automatic transmission and constitutes a portion of a power transmitting path from the transmitting member to the driving wheel;
• an apply device that is provided in the shifting portion and selectively transmits drive torque of the transmitting member to an input rotating member of the shifting portion;
• and a shift operation executing device which is shifted between a non-drive position that places the power transmitting path in a power transmission-interrupted state and a drive position that places the power transmitting path in a power transmittable state, the control method comprising:
• controlling, when the shift operation executing device is shifted from the non-drive position into the drive position, the rotation speed of the transmitting member such that a predetermined rotation speed difference or predetermined rotation speed ratio is obtained between the rotation speed of the transmitting member and the rotation speed of the input rotating member of the shifting portion.
