PROBLEM TO BE SOLVED: To provide a hybrid-vehicle control device capable of accurately and quickly determining sticking of a clutch.SOLUTION: A clutch rotational speed difference &Dgr;N is calculated when a hybrid-vehicle is in a series mode (S10, S12). It is determined whether an engagement-sticking determination timer t reaches or exceeds prescribed time t1 when the clutch rotational speed difference &Dgr;N is within a prescribed range R1 (S12, S14). Fuel cut is performed when the engagement-sticking timer t reaches or exceeds prescribed time t1 (S18). A clutch rotational speed difference &Dgr;N is calculated again (S20). It is determined that the clutch is engagement-stuck when the engagement-sticking timer t reaches or exceeds second prescribed time t2 and when the clutch rotational speed difference &Dgr;N is within a second prescribed range R2 (S22-S26). It is determined that the clutch is not engagement-stuck when the engagement-sticking timer t is less than the second prescribed time t2 and when the clutch rotational speed difference &Dgr;N is outside the second prescribed range R2 (S22, S28). |
