摘要： PROBLEM TO BE SOLVED: To prevent the degradation of the durability and the damage of a motor due to overheating and detect abnormality earlier in an internal combustion engine in which a valve timing is varied by using the motor as the drive source. SOLUTION: An ECU 30 estimates a motor current (drive current for a motor 26) according to a target motor rotational speed, an actual motor rotational speed, and an engine rotational speed. When the estimated motor current exceeds a set value corresponding to a heating limit current value, the varied amount of the target motor rotational speed (corrected amount of rotational speed F/B) output from the ECU 30 to an EDU 31 is limited to limit the motor current controlled for duty by the EDU 31 for suppressing the heating of the motor 26. The variable valve timing device 18 is determined for presence or absence of abnormality according to the deviation between a target cam stem phase and an actual cam stem phase considering that the response of a variable valve timing control is delayed by limiting a motor current when the variable valve timing device 18 is diagnosed for abnormality while a motor current limiting treatment is performed.

摘要： PROBLEM TO BE SOLVED: To provide a vapor fuel treatment apparatus in which purging of a large flow rate of a vapor fuel compatible with suppressing of pressure pulsation with drive of valve members opening/closing flow passages in which the vapor fuel flows.SOLUTION: An ECU 10 calculates a target purge flow rate of a fluid including a vapor fuel to be introduced to an engine 20. The ECU 10 calculates a total maximum flow rate that is a total of a flow rate of the fluid flowing through a first passage 64 in the case where a first valve member 71 is opened most and a flow rate of the fluid flowing through a second passage 65 in the case where a second valve member 81 is opened most. The ECU 10 performs PWM control on a first electromagnetism drive valve 70 and a second electromagnetism drive valve 80 in such a manner that a flow rate of a sum of the flow rate of the fluid flowing through the first passage 64 and the flow rate of the fluid flowing through the second passage 65 is matched with the calculated target purge flow rate. When the calculated target purge flow rate is less than the calculated total maximum flow rate, the ECU controls to make falling timing of a first driving command signal different from falling timing of a second driving command signal.

摘要： PROBLEM TO BE SOLVED: To promptly detect an abnormal condition such that a lock pin is not normally projected, in a variable valve timing apparatus with an intermediate lock mechanism.SOLUTION: If a lock request occurs in a period before learning of a reference phase (for example intermediate lock phase) is completed, a change amount in a VCT phase (valve timing) is monitored, and it is determined that the VCT phase has passed through the intermediate lock phase when the change amount in the VCT phase becomes greater than a "determination value". Here, the "determination value" is set to a value greater than a design value of a phase difference between the most retarded phase (or most advanced phase) and the intermediate lock phase by a range of a product variation of the phase difference or greater. Consequently, it is accurately determined whether the VCT phase has passed through the intermediate lock phase during lock control, by determining whether the change amount in the VCT phase becomes greater than the "determination value", and the abnormal condition such that the lock pin 58 is not normally projected can be detected promptly.

摘要： PROBLEM TO BE SOLVED: To improve responsiveness of valve timing control with respect to change of a control signal (duty value) of an oil pressure regulating valve of a variable valve timing apparatus. SOLUTION: The duty value is calculated based on a deviation of target valve timing and actual valve timing. In a map used when the duty value is converted to a current value, a change rate (control gain) of the current value with respect to the duty value is set to be increased in a current value region corresponding to a dead band (in the vicinity of the current value in which a working fluid supply flow rate becomes approximately zero) and to be reduced in a current value region corresponding to outside of the dead band. Thus, even when the duty value is changed in the vicinity of a holding duty value in which the working fluid supply flow rate becomes approximately zero, flow rate responsiveness in the dead band region of the oil pressure regulating valve with respect to the change of the duty value can be improved, and responsiveness of valve timing control with respect to the change of the duty value can be improved.

摘要： PROBLEM TO BE SOLVED: To improve the response characteristic of valve timing control to a variations in control signal (duty value) for a oil-pressure control valve of a variable valve timing device. SOLUTION: The duty value is computed in accordance with the deviation of target valve timing and actual valve timing, and the duty value is vibrated at a specified amplitude. At this time, the amplitude of the duty value is set at more than a half of the width of a region (dead band) where the responsiveness of valve timing to the variations in the duty value is extremely slow. Consequently, it is possible to change the valve timing favorable in responsiveness against the variations in the duty value (vibration central value) when changing the duty value (vibration central value) from a holding duty value (neighborhood of the center of the dead band) in accordance with variations of the target valve timing as it is possible to extend a vibration range of the duty value to a region favorable in responsiveness outside the dead band even when the vibration central value of the duty value is in the neighborhood of the center of the dead band.
