摘要： A variable valve timing controller adjusts valve timing of an intake valve and/or an exhaust valve by varying a motor speed relative to a camshaft. When an engine is running under a predetermined condition, an actual valve timing is calculated based on a cam angle signal and crank angle signal every when the cam angle signal is inputted. A final valve timing is calculated by adding a valve timing variation amount to the actual valve timing at the time the cam angle signal is outputted. The valve timing amount is periodically calculated based on a difference between a motor speed and a rotational speed of the intake camshaft. When the engine is running under another condition, only actual valve timing at the time the cam angle signal is outputted is calculated.

摘要： An engine valve operation timing control apparatus having a learning control function determines whether both of an actual phase difference angle and a target value between a crankshaft and a camshaft are almost constant for a predetermined time. When both of the actual phase difference angle and the target value become almost constant for the predetermined time, a control value is learned. A controller outputs the learned value to driving means to find a control value thereafter based on the learned value. As a result, the learning means learns the control value in correspondence with a rate of change of the actual phase difference angle and the control value found by the controller compensates for a disturbance factor. The learning operation is updated every time the actual phase difference angle and the target value converge to a constant value and is repeated when the convergence state continues.

摘要： A valve timing control apparatus for a valve timing adjusting unit that adjusts valve timing of an engine. The control apparatus learns a reference position. The control apparatus computes an actual phase based on the learned reference position. The control apparatus computes a target phase based on an engine operational state. The control apparatus controls a hydraulic actuator to perform a phase control based on a difference between the target phase and the actual phase. The control apparatus determines whether the lock mechanism is under an abnormal state. When the control apparatus determines that the lock mechanism is under the abnormal state, the control apparatus is prohibited from performing the phase control that uses the reference position.

摘要： An ECU executes a program including the step of stopping power supply to an electric motor if a phase of an intake valve is in a first region between the most retarded angle and CA. In the case where the phase of the intake valve is in the first region, the rotational speed of relative rotation between the output shaft of the electric motor and a sprocket is reduced at reduction gear ratio R thereby to vary the phase of the intake valve. In the case where the phase of the intake valve is in a second region between CA and the most advanced angle, the rotational speed of the relative rotation is reduced at reduction gear ratio R thereby to vary the phase of the intake valve.

摘要： In a variable valve timing apparatus in which a phase of an intake valve is changed at an amount of change according to a rotational speed of relative rotation between an electric motor as an actuator and a camshaft, the set upper limit value of the rotational speed of relative rotation and a coefficient Nθ of conversion from a required phase-change amount to the rotational speed of relative rotation ΔNm in each control period are set at smaller values at the time of engine stop than at the time of engine operation. As a result, the rotational speed of the electric motor in the VVT operation at the time of engine stop is reduced thereby reducing the operation sound of the variable valve timing apparatus.

摘要： When the engine speed is high (determination of YES at S100), actual intake valve phase 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. 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 by the VVT mechanism in accordance with the operation amount of actuator detected by a motor rotation angle signal is calculated successively, and based on an accumulation of the amount of change, the actual intake valve phase is calculated, and the actual valve timing is detected.

摘要： An ECU executes a program including the steps of: controlling, when the phase of an intake valve is a phase advanced relative to a threshold value CA (FF) (NO in S106), an electric motor operating an intake VVT mechanism by feedback control (S202); and controlling, when the phase of the intake valve is a phase retarded relative to the threshold value CA (FF) (YES in S106), the electric motor by feed-forward control (S200).

摘要： An ECU transmits a pulsed operation command signal, indicating operation commands for an electric motor used as a VVT actuator, to an electric-motor EDU. The electric-motor EDU 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, and the rotational speed command value based on the frequency of the operation command signal. The electric-motor EDU controls the electric motor 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.

摘要： At the time of reference position learning for ensuring accuracy in detecting a valve timing, an operation amount of an actuator is set such that intake valve phase changes to a position of most retarded angle as a reference phase. When the intake valve phase reaches the most retarded angle and the change in the intake valve phase stops (YES at S150), it is determined that the intake valve phase has reached the reference phase and the learning is terminated normally. If the learning operation does not end normally even after the time lapse from the start of learning exceeds a limit time Tlmt, the reference position learning is terminated forcibly (YES at S170), and power supply to the actuator is stopped. Thus, power consumption can be reduced and the apparatus can be protected at the time of reference position learning.
