    • Providing a control apparatus for a vehicular drive system, which is configured to implement a torque reduction control during a shifting action of an automatic transmission, and which permits reduction of the size and cost of an electric circuit including a smoothing capacitor.An electricity-generation-amount-variation restricting region A01 is predetermined such that a point of a vehicle running state lies in the electricity-generation-amount-variation restricting region A01 prior to a moment of determination to perform a shifting action of the automatic transmission, and electricity-generation-amount-variation restricting means 96 implements an electricity-generation-amount-variation restricting control to restrict a rate of increase of a total amount of an electric energy generated by first and second electric motors MG1 and MG2, to a predetermined upper limit value LTGN, when the point of the vehicle running state has moved into the electricity-generation-amount-variation restricting region A01. Accordingly, it is possible to prevent an abrupt increase of the total amount of the electric energy generated by the first and second electric motors MG1 and MG2 prior to a torque reduction control to be implemented during the shifting action of the automatic transmission 22. As a result, the amount of a surplus electric energy can be reduced, so that a required electrostatic capacity of the inverter smoothing capacitor 66 can be reduced. Namely, the size and cost of an electric power source control circuit 60 including the inverter smoothing capacitor 66 can be reduced.
    • 提供一种用于车辆驱动系统的控制装置,其被配置为在自动变速器的换档动作期间执行转矩降低控制,并且允许减小包括平滑电容器的电路的尺寸和成本。 发电量变化限制区域A01是预定的,使得车辆行驶状态点位于发电量变化限制区域A01之前,在确定之前执行自动变速器的换档动作 ,发电量变化限制机构96实施发电量变化限制控制,将由第一和第二电动机MG1,MG2产生的电力的总量的增加率限制为 当车辆行驶状态的点已经移动到发电量变化限制区域A01中时,预定的上限值LTGN。 因此,可以防止在自动变速器22的变速动作期间实施转矩降低控制之前由第一和第二电动机MG1和MG2产生的电能的总量的突然增加。作为 结果,可以减少剩余电能的量,从而可以减少逆变器平滑电容器66所需的静电电容。 也就是说,可以减小包括逆变器平滑电容器66的电力源控制电路60的尺寸和成本。
