Abstract: This invention provides an improved variable cam phaser for an automobile engine equipped with a controller capable of enabling execution of a given phase angle varying command in a shortened response time. The variable cam phaser has two control rotors which are arranged coaxial with a camshaft and rotatable relative to each other under the influence of two electromagnetic actuators and driven by the crankshaft of the engine. The variable cam phaser also has a relative phase angle varying mechanism for varying the relative phase angle of the camshaft relative to the crankshaft. When the two electromagnetic actuators are simultaneously energized, the two control rotors are held mutually unrotatable. However, when the braking torque of one actuator is reduced, the control rotor associated with that actuator is rotated relative to the other control rotor to immediately start the execution of the command.

Abstract: [Problems to be Solved]In the valve opening and closing timing controlled by an ECU, since the responsivity of a phase varying apparatus becomes low and the valve opening and closing timing cannot be appropriately controlled in the state of low engine rpm, desired engine characteristics cannot be obtained. Therefore, it is a problem to be solved by the present invention to provide a method and an apparatus for controlling a phase varying apparatus capable of obtaining the considerably high responsiveness of the phase varying apparatus under condition of low engine rpm.[Solution]The above problem can be solved by a phase control method for controlling a phase varying apparatus constituted so as to calculate an estimated relative angle value one step later by the Kalman filter using a relative angle calculated from rotational velocity values of the associated shafts in the current step and a command value to an electromagnetic clutch in the current step, input the estimated relative angle value to a sliding mode controller as a feedback signal, calculate a command value to the electromagnetic clutch one step later based on the value of the feedback signal and output the command signal.

Abstract: A planetary carrier supports a geared rotor from an inside in a radial direction, and receives a radial load in a first region, which is offset to one end from a center position in an axial direction. A ball bearing roller supports the planetary carrier from an outside in the radial direction in a second region, which is offset to an other end from the center position. The ball bearing roller is a single-row ball bearing roller that has an outer ring supported by a drive rotor, an inner ring which supports the planetary carrier, and a plurality of rolling elements which are rotatably installed in a single row to be in contact with and between the outer and the inner rings. The geared rotor is tilted relative to the axial direction, and contacts a driven rotor in the axial direction. An angle of the geared rotor relative to the axial direction is set to be smaller than a maximum allowable angle at which the inner ring is allowed to be tilted relative to the axial direction.
