    • PROBLEM TO BE SOLVED: To provide a control device for a hybrid vehicle enabling improvement of fuel economy by enhancing thermal efficiency of an engine during catalyst warming-up in the single motor type hybrid vehicle.SOLUTION: During catalyst warming-up control, in a required driving force control part 84, to allow traveling to satisfy change in required driving force of a driver, output from an electric motor MG is changed and gear change of an automatic transmission 18 is performed. Thus while torque of an engine 12 is maintained at an approximately fixed level during traveling, the catalyst warming-up control can be performed appropriately. During the catalyst warming-up control, the catalyst device 58 is warmed up by increasing engine output Pe so as not to exceed exhaust gas purification capacity of a catalyst device 58, and so, thermal efficiency of the engine 12 is made higher than that of an engine having low engine output Pe. Due to this configuration, in a single motor type hybrid vehicle, thermal efficiency of the engine 12 during catalyst warming-up can be enhanced, so as to improve fuel economy.

    • PROBLEM TO BE SOLVED: To accurately determine a vehicular state regarding an engine operation state at the start of an engine whether a starting state of the engine is an automatic start or a loading start.SOLUTION: A determination means is switched based on whether the starting state of the engine 18 is the automatic start of the loading start when the vehicle state regarding the operating state of the engine 18 (for example, characteristics of a fuel F supplied by the engine 18) using an engine torque Tat the start of the engine. Thus, a determination means can accurately determine the vehicle state regarding the operating state of the engine 18 in accordance with whether the starting state is the automatic start or the loading start, for example in response to the fact that an output of the engine torque Tis different at the start of the engine depending on whether the starting state is the automatic start of the loading start.

    • PROBLEM TO BE SOLVED: To improve output response and fuel consumption of an engine during a VVT lead angle delay control for lagging operation of a variable valve mechanism than that at starting of the engine.SOLUTION: An ECU sets a second line L(2) as an engine operation line (S14) during the VVT lead angle delay control for inhibiting a lead angle in a valve opening period of an intake valve (YES in S12). The second line L(2) is an operation line set in consideration to the engine characteristics at VVT non-lead angle (minimum fuel consumption point and maximum torque). The ECU sets a first line L(1) as the engine operation line (S16) after the VVT lead angle delay control (NO in S12). The first line L(1) is an operation line set in consideration to the engine characteristics at the VVT lead angle.
