    • PROBLEM TO BE SOLVED: To provide a device for control of a hybrid vehicle with an engine and a motor mounted thereon as drive sources, which prevents reduction in fuel economy and reduces gear noise.SOLUTION: When a vehicle is in a gear-noise region, if the amount of lubricant oil Lsum1 (a value regarding the amount of lubricant oil in a trans-axle) to a gear noise site is equal to or smaller than a determination value Llimit 1, it is determined that the amount of lubricant to the gear noise site is insufficient, and the engine is controlled on the basis of a first operation line (that preferentially reduces gear noise) M1, thereby reducing gear noise. When the amount of the lubricant oil Lsum1 is larger than the determination value Llimit 1 and there is a sufficient amount of lubricant oil to the gear noise site, the engine is controlled on the basis of a second operation line M2 close to an optimum operation line, to thereby improve the fuel economy.

    • 【課題】デフリングギヤの回転に伴って回転駆動される機械式のオイルポンプを備える車両用動力伝達装置において、オイルの供給経路を構成するパイプを延ばすことなく所定のベアリングの潤滑が可能な構造を提供する。【解決手段】第2オイルポンプP2から吐出されたオイルがオイルパイプ95を通って吐出孔108から吐出されると、そのオイルがオイルガイド110を通ってキャッチタンク90に導かれる。これより、オイルパイプ95をベアリング47aまで延ばすことなくオイルをベアリング47aに供給することができ、オイルパイプ95の製造性の悪化を抑制することができる。また、キャッチタンク90およびオイルガイド110は、ケーシング40に設けられるリブ91、111によって形成されることから、容易に形成することができる。よって、コストアップを抑制しつつ、ベアリング47aを潤滑することができる。【選択図】図3

    • PROBLEM TO BE SOLVED: To provide a control device for improving a fuel consumption rate in a hybrid vehicle that executes abnormal noise reduction control according to the torque of a motor.SOLUTION: In the hybrid vehicle, as a range of a torque command value of a second motor generator, the range being a condition for executing abnormal noise reduction control for preventing abnormal noise (gear rattle) in a power transmission system, when rotation speed deviation ΔNe obtained by subtracting a target engine rotation speed Netarget from a real engine rotation speed Nereal is "0" or a positive value, the range is set to be smaller in such a manner that the abnormal noise reduction control is not started until the torque command value of the second motor generator becomes comparatively lower, thereby improving the fuel consumption rate. Meanwhile, when the rotation speed deviation is a negative value, the range is set to be larger as the value is smaller, and the abnormal noise reduction control is started at timing at which the torque command value of the second motor generator is comparatively higher, thereby preventing the generation of abnormal noise.
