    摘要： Due to the reduction of a discharge amount of a mechanical oil pump by a lowering of the idling rotation speed, a slip in a hydraulic power transmission apparatus and a blow up of an electric motor for running due to a delay of the rising of the oil pressure upon the sudden start and the like are prevented. While avoiding the slip and the blow up, the idling rotation speed is lowered so as to make the engine noise small. When the return determination from the idling state is performed based on the shift operation from P to D, at step S5, a torque TMG2 of a second motor/generator MG2 is temporarily restricted. As a result, upon the sudden start from the idling state, even when the rising of the oil pressure delays, the second brake B2 engaged upon the starting is prevented from slipping, and the second motor/generator MG2 is prevented from blowing up. As a result, while avoiding the slip of the second brake B2 and the blow up of the second motor/generator MG2 due to the hydraulic response delay, an idling rotation speed N Eidl is lowered so that the engine noise can be reduced.

    摘要： The invention provides a rolling/sliding part that can elongate the service life and can increase the static load capacity to improve the indentation resistance to an indentation due to plastic deformation during rest and low-speed rotation. The rolling/sliding part is formed from a steel that contains C: 0.7 to 0.9% by weight and Cr: 3.2 to 5.0% by weight and has a surface layer portion of which surface is carburized. An area ratio of total precipitated carbide of the surface layer portion is set in the range of 15 to 25%. Of the total precipitated carbide present in the surface layer portion, 50% or more by area ratio of carbide is rendered a M7C3 type and/or M23C6 type. An average grain diameter and a maximum grain diameter of the surface layer portion are set in the range of 0.3 to 0.6 μm and at 4 μm, respectively. The surface hardness is set at 62 or more by Rockwell hardness C. A solid solution carbon amount in residual austenite of the surface layer portion is set in the range of 0.95 to 1.15% by weight.
