摘要： A vehicular drive system switchable between a continuously-variable and step-variable shifting states, and a control device for controlling the vehicular drive system so as to reduce a shifting shock of an automatic transmission included in the drive system, which takes place due to an overlap control involving a switching control of the drive system and a shifting control of the automatic transmission.Execution-timing control means 82 is provided to command switching control means 50 and step-variable shifting control means 54 to sequentially execute a switching control by the switching control means to switch transmission mechanism 10 between an electrically established continuously-variable shifting state and a step-variable shifting state, and a shifting control by the step-variable shifting control means to shift an automatic transmission portion 20, even when an overlap control involving the switching control and the shifting control is required, whereby the switching and shifting controls can be rapidly completed. Since the transmission mechanism 10 is not switched during the shifting control of the automatic transmission portion 20, the input speed of the automatic transmission portion 20 will not change due to the switching control, apart from a change of the input speed as a result of the shifting control, making it possible to prevent the complicated shifting control and reduce the consequent shifting shock.

摘要： There is provided a control device for a vehicular power transmitting apparatus of equipped with a differential portion is provided for suppressing a durability decrease of the differential portion or component parts related thereto upon preventing a rotary element of the differential portion from reaching a high-speed rotation. Rotation-stop determining means 72 makes a query as to whether the first rotary element RE1 is lowered in a rotation speed to be stopped during an engine drive mode. If the answer is YES and differential-portion rotation speed determining means 74 makes a positive determination, then engaging-element control-executing means 78 executes engaging element control. This allows a third rotary element RE3 of the differential portion 11, connected to drive wheels 38 via an engaging element of an automatic shifting portion 20, to approach a state available to freewheel. This prevents a second rotary element RE2 and a first electric motor M1 from reaching high-speed rotations caused by a decrease in rotation speed of the first rotary element RE1 in a stop direction and a differential action of the differential portion 11. This enables the prevention of a durability decrease of a power distributing mechanism 16 and the first electric motor M1.

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.

摘要： A transmission mechanism including a switching clutch or brake that is switchable between a continuously-variable shifting state and a step-variable shifting state, and has both an advantage of improved fuel economy provided by a transmission, the speed ratio of which is electrically variable, and an advantage of high power transmitting efficiency provided by a gear type power transmitting device constructed for mechanical transmission of power. While a clutch-to-clutch shifting action of an automatic transmission portion is in a tie-up state, a differential portion is placed in a continuously-variable shifting state by switching control, and engine speed is changed under the control of hybrid control, so as to prevent a drop of the engine speed for thereby reducing a shock of the shifting action, unlike in a non-continuously-variable shifting state of the differential portion in which the engine speed is directly influenced by the tie-up state.
