| description | To suppress delay in progress of down-shift while suppressing deterioration in energy efficiency, when determining the down-shift during regenerative control.SOLUTION: When down-shift is determined during execution of regenerative control, the down-shift can be started so that a progress stage of the down-shift is set to a preparation stage, which can shorten delay time in the down-shift more in comparison with a case where starting of the downs-shift can be delayed until an absolute value of a torque difference between a target value and an actual value of regenerative braking torque is equal to a predetermined torque difference or lower. Further, even when the preparation stage is completed, the completed preparation stage is maintained until the absolute value of the torque difference is equal to the predetermined torque difference or lower and a torque phase is started and the down-shift is progressed after the absolute value of the torque difference falls below the predetermined torque difference, which enables the actual value of the regenerative braking torque to get close to the target value, in the preparation stage in which shift-shock is suppressed from occurring even if the actual value of the regenerative braking torque is increased.SELECTED DRAWING: Figure 2
【課題】回生制御中にダウンシフトを判断した際に、エネルギー効率の低下を抑制しつつダウンシフトの進行の遅れを抑制する。【解決手段】回生制御が行われているときにダウンシフトを判断した場合には、ダウンシフトの進行段階を準備段階とするようにダウンシフトが開始させられるので、回生制動トルクの目標値と実際値とのトルク差の絶対値が所定トルク差以下になるまでダウンシフトの開始自体を遅延させることに比べてダウンシフトの遅延時間を短縮することができる。又、準備段階が完了させられても、トルク差の絶対値が所定トルク差以下になるまでは準備段階が完了した状態で維持させられ、トルク差の絶対値が所定トルク差以下になってからトルク相が開始させられてダウンシフトが進行させられるので、回生制動トルクの実際値が増加させられても変速ショックが発生し難い準備段階において、回生制動トルクの実際値が目標値に近づけられる。【選択図】図２ |
