To make both gear shift in which gear shift shock is suppressed by controlling input torque from a power source and maintenance of required acceleration by a driver compatible, without slipping a friction element.SOLUTION: The power train control device comprises at least a motor 3 as a power source. An automatic speed changer 4 at an output side of the motor 3 comprises: a maintenance-side friction element 40 whose fastening force can be maintained during speed change; a fastening-side friction element 50 which can be switched from a released state into a fastened state; and a releasing-side friction element 80 that can be switched from the fastened state to the released state, and further has control means 200 that controls fastening/releasing of the friction elements 50 and 80 and controls the motor 3. The control means 200 controls rotation of the fastening-side friction element 80 while maintaining the vehicle at required acceleration by a driver, by controlling the motor 3 in a state where the fastening-side friction element 80 and the releasing-side friction element 50 are released, during predetermined speed change, so as to fasten the fastening-side friction element 80 at timing at which the rotation is made at predetermined rotation speed.SELECTED DRAWING: Figure 5
【課題】摩擦要素をスリップさせることなく、動力源からの入力トルクの制御によって変速ショックが抑制された変速と、ドライバの要求加速度の維持を両立させる。【解決手段】パワートレインの制御装置は、動力源として少なくともモータ3を備え、該モータ3の出力側の自動変速機4は、変速時に締結力が維持される維持側摩擦要素40と、解放状態から締結状態に切り換えられる締結側摩擦要素50と、締結状態から解放状態に切り換えられる解放側摩擦要素80とを備え、これらの摩擦要素50、80の締結解放制御と、モータ3の制御とを行う制御手段200を有し、該制御手段200は、所定の変速時に、締結側摩擦要素80および解放側摩擦要素50を解放した状態で、モータ3を制御することによって、車両をドライバ要求加速度に維持しつつ締結側摩擦要素80の回転を制御し、該回転が所定回転数になるタイミングで締結側摩擦要素80を締結させる。【選択図】図5
