    Abstract: PROBLEM TO BE SOLVED: To provide a control device for a variable valve mechanism capable of performing control to maintain a stable combustion state even in cold condition.
    SOLUTION: The number of valve stop cranking times i and the number of cycle times j are set based on engine water temperature, intake air temperature, actual compression ratio, and cranking rotating speed (step 101). When it is determined that the number of the cycle times j is larger than 0, a valve stop cranking cycle is started (step 103). Concretely, i valve stop crankings are started in a state of closing intake and exhaust valves and inhibiting ignition by an ignition plug. When the step 103 ends, processing returns to the step 101.

    Abstract: PROBLEM TO BE SOLVED: To solve a problem of degradation in vehicle power performance caused by delay in responsiveness of an engine output displacement variable mechanism resulting in continuing a period wherein power actually output is smaller than required power for a while, when an operation point is changed between different operation lines, in a conventional hybrid vehicle including an engine output variable mechanism and having a plurality of engine operation lines. SOLUTION: When the engine operation point is changed from a first operation line to a second operation line, firstly, an operation point outputting the required power on the first operation line is used as a target operation point. The engine operation point is controlled to be moved toward the target operation point along the first operation line, and thereby the required power is quickly output regardless of delay in responsiveness of the engine output variable mechanism. Then the operation point is controlled to be moved on an equal power line of the required power and to be changed according to the responsiveness of the engine output variable mechanism.

    Abstract: PROBLEM TO BE SOLVED: To smoothly switch power from a motor to an engine in a direct coupled type hybrid vehicle. SOLUTION: An engine 3, a motor generator 5 and an automatic transmission 7 are connected and these are controlled by a hybrid ECU 11. A complete explosion estimating part 17 estimates that the engine 3 starts to generate positive torque when the engine 3 is started. The estimation is performed by engine speed, fuel injection and an ignition processing. A power switching control part 19 switches power from the motor generator 5 to the engine 3 based on the estimation result. Preferably, a motor output is reduced by moderating. Preferably, a feedback control is performed for the motor output so as to prevent engine speed from lowering below a prescribed value. Engine torque after the engine 3 starts to generate positive torque is estimated and the motor output may be reduced so as to cancel the engine torque.
