In an engine start-up device, engine start-up means 94 starts up an engine 8 upon altering a start-up method of the engine 8 for a shifting of an automatic shifting portion 20 relative to a start-up method of the engine 8 for a non-shifting of an automatic shifting portion 20. Thus, an operation to start-up the engine 8 is avoided from adversely affecting the shifting of the automatic shifting portion 20. The operation to start-up the engine 8 begins to be executed during the shifting of the automatic shifting portion 20, enabling further improved response in acceleration required by a driver than that achieved when the operation is commenced after the automatic shifting portion 20 has completed the shifting.

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 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.

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.

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.

An oil return structure for a vehicle drive apparatus includes a hydraulic control apparatus disposed below an oil supply target device to which oil for lubricating and cooling is supplied; and an oil pan that retains the oil that is supplied to the oil supply target device is provided below the hydraulic control apparatus, wherein a bypass oil path is formed in a body of the hydraulic control apparatus, the bypass oil path being structured in order to guide the oil from the oil supply target device from an upper surface of the body, inside the body and then discharge the oil from a side surface of the body.
摘要:
A control device for a vehicular drive system controls an engine rotation speed (NE) in a way not to exceed an engine upper limit rotation speed (NELIM). The engine upper limit rotation speed is altered depending on a second electric motor rotation speed (NM2) such that a second electric motor increasing possible rotation speed (NM2max), influenced with the engine upper limit rotation speed (NELIM), is altered depending on the second electric motor rotation speed (NM2). Consequently, when the second electric motor rotation speed (NM2) is relatively high, the engine upper limit rotation speed (NELIM) can be lowered, and the second electric motor increasing possible rotation speed (NM2max) can be altered to a lower level for suppressing an increase in rotation speed of a second electric motor (M2). Thus, the second electric motor is improved in durability thereof.
