Abstract
변속중에 토크 상태 기간 및 관성 상태 기간 각각으로 적정한 라인압 설정을 진행한다. 토크 TQe 및 관성 토크 TQi를 각기에 산출하는 (S3, S4), 그리고 변속중의 토크 상태에 있어서는 엔진출력 토크 TQe를 기어 열 입력 토크 TQ로 간주한다(S8). 한편, 업 시프트에 있어서 관성 상태에 있어서는 엔진출력 토크 TQe와 관성토크 TQi의 가산치를 기어 열 입력 토크 TQ로 한다(S9). 또, 다운 시프트에서 관성상태에 있어서는 엔진출력 토크 TQe에서 관성토크 TQi를 감산한 값을 기어 열 입력 토크 TQ로 한다(S11). 그리고 상기 기어 열 입력 토크 TQ를 라인압 PL로 전환하여 라인압 제어를 진행한다(S12).During shifting, an appropriate line pressure setting is performed for each of the torque state period and the inertia state period. The engine output torque TQe is regarded as the gear train input torque TQ in the torque state in which the torque TQe and the inertia torque TQi are respectively calculated (S3, S4), and during the shifting operation (S8). On the other hand, in the inertia state in the upshift, the added value of the engine output torque TQe and the inertia torque TQi is set as the gear heat input torque TQ (S9). In the inertia state in the downshift, the gear heat input torque TQ is obtained by subtracting the inertia torque TQi from the engine output torque TQe (S11). Then, the gear train input torque TQ is switched to the line pressure PL to perform line pressure control (S12).
