    摘要： If the accelerator pedal condition is a power-on condition and the gearshift type is an upshift, or the accelerator pedal condition is a power-off condition and the gearshift type is a downshift, then a torque for engaging the next-gear-position gearshift means is established based on the engine torque to be transmitted from the engine to the next-gear-position gearshift means, and an inertia torque required to make the rotational speed of the input member of the next-gear-position gearshift means vary as desired with respect to the gearshift. If the accelerator pedal condition is a power-on condition and the gearshift type is a downshift, or the accelerator pedal condition is a power-off condition and the gearshift is an upshift, then the ratio between the rotational speeds of the input and output members of the next-gear-position gearshift means is detected. The torque for engaging the next-gear-position gearshift means is lowered after the gearshift is started until the detected rotational speed ratio reaches a predetermined value. After the detected rotational speed ratio has reached the predetermined value, the engaging torque is set to a vaslue large enough to engage the gearshift means.

    摘要翻译： 如果加速器踏板状态是开机状态，换挡类型是升档，或者加速踏板状态是断电状态，换档类型是降档，则用于接合下一档位换档 基于要从发动机传递到下一档位换档装置的发动机扭矩建立装置，并且使得使下一档位换档装置的输入构件的转速变化的惯性转矩变化 相对于换档。 如果加速器踏板状态是开机状态，换挡类型是降档，或者加速器踏板状态是断电状态，换档是升档，则输入和输出构件的转速之间的比率 检测到下一档位换挡装置。 在变速起动之后，下降档位换档装置的转矩降低，直到检测到的转速比达到预定值。 在检测到的转速比已经达到预定值之后，接合扭矩被设定为足够大以接合换档装置的马达。
