PROBLEM TO BE SOLVED: To provide a power generation control device of a hybrid vehicle which can suppress that an operation sound of an electric load becomes large abruptly at a start of power generation, and can suppress that an occupant feels discomfort.SOLUTION: When it is determined that the charge of a first power accumulator 30 is necessary when an EV traveling mode which is performed by an HCU 10 during the supply of power to a general load 37 is released, and an engine 2 is restarted by an ISG 20, a power generation control device of a hybrid vehicle acquires a target power generation amount on the basis of an electric load amount of the general load 37, and generates power by the ISG 20 so as to obtain the target power generation amount. An ECM 11 has a plurality of different first and second modes for obtaining the target power generation amount, and selects an arbitrary mode from the first mode and the second mode according to a set value of the electric load amount of the general load 37.SELECTED DRAWING: Figure 1
【課題】発電開始時に電気負荷の作動音が急激に大きくなることを抑制することができ、乗員に不快感を与えることを抑制できるハイブリッド車両の発電制御装置を提供すること。【解決手段】一般負荷37に電力を供給中にHCU10によって実施されているEV走行モードが解除され、ISG20によってエンジン2を再始動する場合に、第1蓄電装置30の充電が必要と判断したら、一般負荷37の電気負荷量に基づいて目標発電量を求め、目標発電量となるようにISG20によって発電を実施する。ECM11は、目標発電量に到達させるための複数の異なる第1モードおよび第2モードを有し、一般負荷37の電気負荷量の設定値に応じて第1モードおよび第2モードから任意のモードを選択する。【選択図】図1
