Abstract: When the engine speed is high (determination of YES at S100), actual intake valve phase (IV(q)) is calculated based on rotation phase difference between rotation angles of crankshaft and camshaft, detected by using a crank angle signal and a cam angle signal, and actual valve timing is detected therefrom (S110). When the engine speed is low (determination of NO at S100) and the crank angle signal and cam angle signal are unstable, an amount of change in camshaft rotation phase (dIV(q)) by the VVT mechanism in accordance with the operation amount of actuator detected by a motor rotation angle signal is calculated successively (S120), and based on an accumulation of the amount of change (dIV(q)), the actual intake valve phase (IV(q)) is calculated, and the actual valve timing is detected (S130).

Abstract: In the case where an intake valve has its phase in a first region between a most retarded angle and CA(1), the rotational speed of relative rotation between an output shaft of an electric motor and a sprocket is reduced at a reduction gear ratio R(1) to change the phase of the intake valve. In the case where the intake valve has its phase in a second region between CA(2) and a most advanced angle, the rotational speed of relative rotation is reduced at a reduction gear ratio R(2) to change the phase of the intake valve. As long as the rotational direction of relative rotation is the same, the phase of the intake valve is changed in the same direction for both of the first region between the most retarded angle and CA(1) and the second region between CA(2) and the most advanced angle.

Abstract: An ECU (4000) transmits a pulsed operation command signal (SGl), indicating operation commands for an electric motor (2060) used as a VVT actuator, to an electric-motor EDU (4100). The electric-motor EDU (4100) recognizes the combination of the direction in which the actuator should be operated (actuator operation direction) and the control mode based on the duty ratio of the operation command signal (SGI), and the rotational speed command value based on the frequency of the operation command signal (SGI). The electric-motor EDU (4100) controls the electric motor (2060) according to the control commands. The duty ratio indicating the combination is set such that even if the duty ratio is falsely recognized, a false recognition concerning the actuator operation direction is prevented, such false recognition causing the valve phase to change in an undesirable direction, and even if the actuator operation direction is falsely recognized, the rate of change in the phase is restricted.

Abstract: An engine has a variable valve actuation mechanism that varies lift characteristics of an intake valve. An idle speed control apparatus has a control section for controlling an intake air amount of the engine in an idle state for adjusting an actual engine speed to a target engine speed. The control section sets a control amount related to control of the intake air amount in correspondence with the lift characteristics, which are varied by the variable valve actuation mechanism. Accordingly, the engine speed in the idle state is effectively controlled in correspondence with changes of the lift characteristics.
