PROBLEM TO BE SOLVED: To make it possible to properly switch an EV traveling mode, series HEV traveling mode, and parallel HEV traveling mode according to a driver's intention of making much account of power performance, fuel economy, or the like.SOLUTION: If a driver wants to drive while making much account of power performance, a domain within which a series HEV traveling mode is selected is made narrower than it is in a normal driving mode because a limit of the domain is changed from an SP1 switching line for normal driving to an SP2 switching line. Accordingly, a transition is swiftly made from an EV driving mode to a parallel HEV driving mode, and drivability improves. If the driver wants to drive while making much account of fuel economy, the domain within which the series HEV driving mode is selected is made wider than it is in the normal driving mode because the limit of the domain is changed from the SP1 switching line for normal driving to an SP3 switching line. Accordingly, a time or the number of occasions during or on which the driver drives in the series HEV driving mode increases. Therefore, an engine 12 can be actuated at an optimal running point while being unsusceptible to a vehicle speed V, and fuel economy improves.

    【課題】動力性能重視や燃費重視等の運転者の意図に応じてEV走行モード、シリーズHEV走行モード、およびパラレルHEV走行モードが適切に切り換えられるようにする。【解決手段】運転者が動力性能を重視した走行を望んでいる場合、シリーズHEV走行モードが選択される範囲がノーマル時のSP1切換線からSP2切換線に変更されてノーマル時よりも狭められるため、EV走行モードからパラレルHEV走行モードへ速やかに移行するようになり、ドラビリ性能が向上する。また、運転者が燃費を重視した走行を望んでいる場合には、シリーズHEV走行モードが選択される範囲がノーマル時のSP1切換線からSP3切換線に変更されてノーマル時よりも広くされるため、シリーズHEV走行モードで走行する時間や機会が多くなり、車速Vに影響されることなくエンジン12を最適な運転点で作動させることが可能で、燃費が向上する。【選択図】図3
