摘要： In a control device for a vehicular power transmitting device, if engine torque TE generated with using a fuel other than a basic fuel by an internal combustion engine (8) connected to a shifting mechanism (10) for power transmitting capability, exceeds torque TES generated with using a basic fuel, a downshift is initiated at a lower accel-opening than that at which the downshift is initiated with using the basic fuel. That is, the shifting is performed at a shift point enabling the suppression of a torque increase in consideration of an increase in engine torque TE generated by the internal combustion engine, thereby preventing rotary elements of the shifting mechanism (10) from reaching high-speed rotations during a transition in downshift. This minimizes a drop in durability of the shifting mechanism (10).

摘要： This invention relates to a control device for a vehicular power transmitting device. The control device has shifting-point altering means 108 operative such that when a second electric motor M2 is operated with priority to obtain a charging efficiency and/or electric power generating efficiency, a shifting point for a vehicle to run under a decelerating state (during a coast running state) is altered to a point on a higher vehicle speed than that at which a shifting point for a running-performance-conscious state is set. Therefore, when the second electric motor M2 is operated with priority for generating electric power, a downshift is initiated at a high vehicle speed than that at which the downshift is initiated at a shifting point for a running-performance-conscious state. This increases a rotation speed NM2 of the second electric motor M2, resulting in an increase in regeneration amount (electric power generation amount) of the second electric motor M2.
