    Abstract: PURPOSE:To improve the accuracy of the compensating control between cylinders in a device to control the control parameters of an engine so that the fluctuation between cycles of the generated torque of the specified cylinder of the multi-cylinder internal combustion engine may be the target value. CONSTITUTION:In a control device 31 of an engine 21, the step 211 makes a judgement if or not the torque fluctuation control is being executed. The steps 212 and 213 make a judgement if or not the torque fluctuation value DTRQISM to be used in the torque fluctuation control routine is a value close to the target torque fluctuation quantity KTH. The step 215 makes a judgement if or not DTRQISM is far deviated from the KTH value. When a judgement is made that the value DTRQISM is converged to the value close to the value KTH(Steps 214,217), the compensating coefficient computation between cylinders after the step 218 and subsequent steps are executed. When the value DTRQISM is not converged to the value close to KTH(Step 215), the counter CCPSFB is cleared (Step 216) to complete this routine.

    Abstract: PROBLEM TO BE SOLVED: To provide an engine control device improving accuracy of ignition timing in undetermined engine speed when an engine is started in an early stage.
    SOLUTION: In this engine control device, engine ignition timing determined based on a reference rotational position and an Ne signal corresponding to a missing tooth part from a crankshaft sensor is corrected with respect to a delay in a response according to the engine speed. When early start-up is performed by an economical running system (ST1), it is determined that it is before first ignition (ST2), and the engine speed is not determined (ST3), a preset value based on a correction value with respect to the delay in the response according to cranking speed when the engine is restarted, with an environmental temperature condition satisfied, is read from an ECU (ST4), and the correction value with respect to the delay in the response according to the engine speed when determining the first ignition timing in restarting the engine is set to the preset value (ST5).

    Abstract: PROBLEM TO BE SOLVED: To reduce torque shock generated on a driving shaft in association with start and stop of an internal combustion engine. SOLUTION: An air-fuel ratio is set to a lean condition, a throttle valve opening is set to a value SVP1, a timing advance FT is set to the latest timing FT1, and an intake valve timing is set to the latest timing VT1 so as to operate an engine by a target engine speed Ne* without a torque output, and the engine is started by a start torque from a motor MG1. At this time, a motor MG2 is controlled so as to cancel the start torque outputted to a ring gear connected to the driving shaft. After start, the air-fuel ratio is set as a stoichiometric value, the throttle valve opening, the timing advance, and the intake valve timing are gradually increased toward an optimal value, the output torque from the engine is set as a target torque Te*, and also the sum of torque outputted from the engine to the ring gear is set as a target torque Tr* by controlling the motor MG2.

    Abstract: PURPOSE:To relax influence of deposit attached on a means for detecting combustion pressure by making control to more quickly set a finishing timing of a sampling period for calculating a combustion variable quantity as engine rotational speed is lower based on an engine condition. CONSTITUTION:Combustion pressure in a specified cylinder in an internal combustion engine M1 is detected by a means m2, and also the variable quantity of the detected combustion pressure is calculated by a means M3. A combustion variation quantity corrective coefficient at the specified cylinder or all the cylinders for matching a calculation value of the combustion variable quantity to a target value, is calculated by a means M4. An engine control parameter for each cylinder is controlled in its correcting by a means M5 based on the combustion variation quantity corrective coefficient. In this case, the condition of the internal combustion engine M1 is detected by a means M6. A finishing timing of a sampling period for calculating the combustion variation quantity is controlled by means M7 to be more quickly set as the engine rotational speed is lower based on the detected engine condition. Consequently, influence of deposit attached to the means M2 is made hard to be received.
