摘要:
A control device of a vehicle includes a first electric motor; a differential mechanism having a rotating element coupled to the first electric motor, a rotating element that is an output rotating member coupled to drive wheels in a power transmittable manner, and a rotating element coupled to a non-rotating member by actuation of a lock mechanism; and a second electric motor coupled to the drive wheels in a power transmittable manner. During motor running for running with output torques from the first electric motor and the second electric motor used together in an actuated state of the lock mechanism, a drive torque shared by the first electric motor is made smaller in a requested drive torque when a rotation speed of a pinion making up the differential mechanism is higher.

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.

A hybrid drive system includes an engine; at least one rotating electric machine, wherein the engine and the at least one rotating electric machine are capable of driving a vehicle; and a controller. The controller starts a load limit control that limits a load exerted to the rotating electric machine when a temperature of the rotating electric machine exceeds a load limit start temperature; detects a loading state or a towing state of the vehicle; and determines the load limit start temperature based on the loading state or the towing state detected.

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 control device includes drive-force source start control means for switching start modes of an engine depending on a vehicle condition to achieve an appropriate start mode for the engine depending on the vehicle condition, so that for instance a contracted drive range by a second electric motor can be avoided.
摘要:
The present invention provides a control device for a vehicular drive apparatus with a structure of enabling the suppression of gearshift shock occurring during concurrent shifting executed of a first shifting portion and a second shifting portion. When the concurrent shifting are executed around the same time in which a down shift in one of a differential portion (first shifting portion) and an automatic shifting portion (second shifting portion) and an upshift in the other of them are executed, a first electric motor is caused to control a rotation speed of a second rotary element (sun gear). Thus, a shifting progress state upon the concurrent shifting is controlled. This causes shifting directions i.e., variation of the engine rotation speed in shifting of a shifting mechanism to be set in a unidirectional, enabling the suppression of gearshift shock.

A control method for a vehicular drive apparatus that includes a driving power source that includes an engine and a motor, and a shift portion provided in a power transmission path from the driving power source to a drive wheel, includes staring the engine by executing an engine speed control that increases an engine speed to a predetermined engine speed or higher, and executing an engine torque generation control that generates engine torque by supplying fuel and igniting the fuel at the predetermined engine speed or higher. In the case where the controller determines that the period during which the shift of the shift portion is performed overlaps the period during which the engine is started, the engine is started by executing the engine speed control during the shift of the shift portion, and executing the engine torque generation control after the shift of the shift portion is completed.
