    摘要： A control device for hybrid vehicle is provided with property alter means 88 that is operative based on whether or not an EV running mode is set and alters a given property used for determining demanded output torque TOUTt of a transmission mechanism by referring to an accelerator opening Acc. This suppresses occurrence of engine startup to meet a requirement for the EV running mode to be initiated. The property alter means alters the given property such that during an EV running mode turn-on state, demanded output torque TOUTt determined based on the accelerator opening Acc has a lower value than that set for an EV running mode turn-off state. That is, this causes a drop in sensitivity of demanded output torque TOUTt determined based on the accelerator opening Acc. Thus, the occurrence of engine startup induced upon depressive operation of an accelerator pedal during the EV running mode is suppressed.

    摘要： A power transmission apparatus for a vehicle includes a main drive power source; a first shift unit that has an input shaft connected to the main drive power source; a second shift unit; at least one electric motor connected to a rotating element of the first shift unit or a rotating element of the second shift unit so that the rotational speed of the electric motor is changed in accordance with a gear-shift of the first shift unit or the second shift unit, and that is able to control the rotational speed of the main drive power source by changing its rotation; and a control unit that executes control so that the direction in which the rotational speed of the main drive power source is changed is maintained constant throughout a gear-shift, when the gear-shift is a simultaneous gear-shift in which the gear-shift of the first shift unit and the gear-shift of the second shift unit are performed simultaneously and a gear ratio of the first shift unit and a gear ratio of the second shift unit are changed in opposite directions. With the control executed by the control unit, it is possible to effectively suppress occurrence of shift shock.

    摘要： When the power transmitting path in an automatic shifting portion (20) is interrupted, a Co-lock control is executed to allow a differential portion (11) to be placed in a non-differential or nearly non-differential state with rotary elements (RE1 to RE3) kept in a unitary rotation. Thus, an engine (8), a first electric motor (M1) and a second electric motor (M2) rotate at an identical or nearly identical speed. Then, for the purpose of controlling the second electric motor (M2) at a rotation speed below a permit rotation speed, it may suffice for the first and second electric motors (M1) and (M2) to be driven in a direction to lower relevant rotation speeds while monitoring any one of an engine rotation speed, a first-motor rotation speed and a second-motor rotation speed. This allows such a control to be easily executed, thereby preventing the second electric motor from reaching a high speed rotation.
