Power transmission apparatus for vehicle |
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.
