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).

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.

The hydraulic control apparatus includes a separating plate that is interposed between an upper valve body and a lower valve body. The separating plate and the lower valve body provide a projecting portion that projects toward a discharge opening side of the oil pump with respect to the upper valve body. A first oil feed path is provided at the projecting portion, is formed between the separating plate and the lower valve body, and receives the hydraulic oil from the oil pump and guides the hydraulic oil to an upper valve body disposition side.

In a vehicular power transmitting apparatus provided with an electrically-controlled differential portion in which controlling an operating state of an electric motor controls a differential state of a differential mechanism, a control device for starting up a drive force source in an appropriate mode depending on a vehicle condition can be provided.

The present invention relates to a control device for a vehicle power transmitting apparatus. The vehicle power transmitting apparatus includes an electrically controlled differential portion of which differential state is controlled between a rotation speed of an input shaft to which power of an engine is input and a rotation speed of an output shaft by controlling an operational state of an electric motor connected to a rotary element of a differential mechanism, and a shifting portion constructing a part of a power transmitting path. The control device includes a correspondence controlling unit for controlling the engine or the vehicle power transmitting apparatus to allow the shifting portion to be shifted when a command for shifting by a manual shift operation is issued in an operating region restricting the shifting of the shifting portion.

A control apparatus for a vehicular power transmitting apparatus includes, in series, i) a differential portion which is provided with a differential mechanism having a differential function with respect to an input shaft and an output shaft, in which the differential mechanism is switched between a differential state and a non-differential state, and ii) a stepped shifting portion that shifts between a plurality of gears in a stepped manner. During a shift with a switch between the differential state and the non-differential state in the differential portion, the control apparatus either maintains the gear at that time or shifts into a gear that is adjacent to that gear.
