    Abstract: A valve timing controller has a case which defines a fluid chamber therein. A magnetic viscosity fluid is enclosed in the fluid chamber. The magnetic viscosity fluid including magnetic particles and its viscosity varies according to a magnetic field applied thereto. A coil and a control circuit applies magnetic field to the magnetic viscosity fluid to variably control a viscosity thereof. A brake rotor is rotatably accommodated in the fluid chamber and receives a brake torque from the magnetic viscosity fluid according to the viscosity thereof. A phase adjusting mechanism is connected to the brake rotor for adjusting a relative rotational phase between the crankshaft and the camshaft according to the brake torque. When it is estimated that the engine will be started, the coil is energized to generated heat in the magnetic viscosity fluid.

    Abstract: An electric power supply driver executes duty control of turning on and off of a selected switching element to supply electric power to a corresponding stator coil in a case where an actual rotational direction and a target rotational direction of a motor shaft coincide with each other. Furthermore, the driver sets an on-duty ratio of the selected switching element below a lower limit value, which is at least required to rotate the motor shaft through the power supply to each corresponding stator coil in a case where the actual rotational direction and the target rotational direction do not coincide with each other.

    Abstract: A valve timing controller has the drive circuit which performs a feedback control of the energization to the electric motor based on the target rotation speed and the actual rotation speed of the electric motor, and rotates the electric motor to the target rotation direction. An invalid switch part of the drive circuit suspends the feedback control at the time of change of the target rotation direction.

    Abstract: A closed-loop control for a cam phase adjustment mechanism includes gain terms that are adaptively adjusted to optimize the rate of response of the control to changes in the desired cam phase. The rate of response of the cam phase adjustment mechanism is sampled under specified operating conditions or during certain repeated engine events that involve a change in the desired cam phase, and the deviation of the measured rate of response from the nominal rate of response is determined and used to adjust the closed-loop control gains for restoring the nominal response.
