Abstract
(EN)

PROBLEM TO BE SOLVED: To suppress transmission shock during shifting of a transmission while suppressing overcharge of an electricity storage device.

SOLUTION: In the automobile, a first motor, an engine, and a drive shaft are connected to a sun gear, a carrier, and a ring gear of a planetary gear mechanism, and the drive shaft is connected to a second motor via the transmission. In control of the engine, the two motors, and the transmission, when upshifting the transmission in a state of outputting positive torque from the second motor, and torque transmitted to the drive shaft from the second motor declines (when a flag F1 for determining a torque phase is a value 1), by reducing a target rotational frequency Ne* of engine, and reducing a torque command Tm1* (negative torque) of the first motor, direct transmission torque directly transmitted from the engine to the drive shaft via the first motor is increased, and a torque command Tm2* added with positive predetermined torque Tup is set such that electric power generated by the first motor following the increase of the direct transmission torque is used in the second motor (S200-S260).

【課題】蓄電装置が過充電するのを抑止しつつ変速機を変速する際の変速ショックを抑制する。
【解決手段】遊星歯車機構のサンギヤ,キャリア,リングギヤに第1モータ,エンジン,駆動軸が接続されると共に変速機を介して駆動軸に第2モータが接続された自動車において、第2モータから正のトルクが出力されている状態で変速機をアップシフトする際に第2モータから駆動軸へ伝達されるトルクが低下するとき(トルク相を判定するフラグF1が値1のとき)、エンジンの目標回転数Ne*を減少させて第1モータのトルク指令Tm1*(負のトルク)を小さくすることにより第1モータを介してエンジンから駆動軸に直接伝達される直達トルクを大きくしこれに伴って第1モータで発電される電力が第2モータで消費されるよう正の所定トルクTupを上乗せしたトルク指令Tm2*を設定して(S200〜S260)、エンジンと二つのモータと変速機とを制御する。
