CONTROL DEVICE OF HYBRID VEHICLE

To further expand an electric traveling region by suppressing the consumption of electric charges stored in an electric-traveling main power accumulation device, in a hybrid vehicle.SOLUTION: A control device of a hybrid vehicle controls the hybrid vehicle which comprises: a traveling electric motor 4 which can supply drive forces to drive wheels 62; an internal combustion engine 1 which can supply the drive force to a generator 2; a motoring electric motor 2 which can supply the drive force to the internal combustion engine 1; a main power accumulation device 3 which stores power, and can supply the power to the electric motor 4 and the electric motor 2; and an auxiliary power accumulation device 7 which stores power, and can supply the power to an electric load 8 other than the electric motor 4 and the electric motor 2. When starting the stopped internal combustion engine 1, the control device 0 supplies the power to the motoring electric motor 2 from both the main power accumulation device 3 and the auxiliary power accumulation device 7 at only an initial stage of motoring for rotationally driving the internal combustion engine 1 by the motoring electric motor 2, and after that, the control device is transited to a state for supplying the power to the motoring electric motor 2 from the main power accumulation device 3.SELECTED DRAWING: Figure 1 【課題】ハイブリッド車両にあって、電気走行用の主蓄電装置に蓄えた電荷の消費を抑制して電気走行領域をより拡大する。【解決手段】駆動輪６２に駆動力を供給できる走行用電動機４と、発電機２に駆動力を供給できる内燃機関１と、内燃機関１に駆動力を供給できるモータリング用電動機２と、電力を蓄えるとともに電動機４及び電動機２に電力を供給できる主蓄電装置３と、電力を蓄えるとともに電動機４及び電動機２以外の電気負荷８に電力を供給できる補助蓄電装置７とを具備するハイブリッド車両を制御するものであって、停止した内燃機関１を始動するにあたり、モータリング用電動機２により内燃機関１を回転駆動するモータリングの初期のみ、主蓄電装置３及び補助蓄電装置７の両方からモータリング用電動機２に電力を供給し、しかる後主蓄電装置３からモータリング用電動機２に電力を供給する状態へと移行する制御装置０を構成した。【選択図】図１
