摘要： Displacement of a mechanical element is accurately detected by a simple and inexpensive structure. To provide displacement detecting device including: a mechanical element capable of being displaced; a magnet connected to the mechanical element and magnetized in displacement direction of the mechanical element; and a magnetic sensor for detecting a magnetic flux generated by the magnet and outputting a sensor output corresponding to a detected magnetic-flux value, so as to detect displacement of the mechanical element in accordance with the sensor output. In one embodiment, a Hall element is used as the magnetic sensor and the magnet longer than distance of movement of the mechanical element is used. Thus, an output having a linear relation with displacement of the mechanical element is obtained, and detection of the displacement is easily implemented. The displacement detecting device can be applied to an actuator of intake/exhaust valves of an engine. In another embodiment, a magnetic material provided between the Hall element and a spring to reduce the disturbance caused by the spring. Moreover, a transfer shaft connected to the intake/exhaust valve is made of a non-magnetic material or a material having characteristics close to the non-magnetic material to reduce the effect of leakage flux.

摘要： A controller for an electromagnetic actuator comprises a pair of springs acting on opposite directions, and an armature connected to the springs. The armature is held in a neutral position given by the springs when the armature is not activated. The actuator also comprises a pair of electromagnets for driving the armature between two end positions. In response to a release of the armature held in one of the end positions, the controller applies brake to the armature according to a load condition of the armature. In high-load conditions, the valve can surely be opened without additional electric power. In low-load conditions, the armature is prevented from colliding with a yoke of the electromagnet. The application of brake includes over-excitation operation, flywheel operation and suspension of power supply. In the over-excitation operation, voltage is applied to the electromagnet corresponding to one of the end positions from which the armature is released for a first period. The first period may be determined according to a load condition of the armature. After the first period elapses, flywheel current is supplied to the electromagnet for a second period. After the second period elapses, power supply to the electromagnet is suspended. Appropriate combination of over-excitation operation, flywheel operation and suspension of power supply allows the braking force to be adjusted according to a load condition of the armature.

摘要： An electromagnetic actuator is equipped with two springs which act in opposite directions, and an armature that is connected to the springs and is supported in an unactivated state in a neutral position provided by the two springs. The armature is coupled to a mechanical element such as a valve of an engine. The actuator includes a pair of electromagnets that drive the armature between a first terminal position and a second terminal position, and a power supply device that controls the voltage supplied to the electromagnet attracting the armature to a constant voltage when the armature is driven from one of the terminal positions to the other terminal position. The voltage supplied to the electromagnets is maintained at a constant value and the larger current flows in the larger is the gap between the armature and the yoke and smaller is the counter electromotive force.

摘要： In an alternate energization process for alternately energizing a valve closing electromagnet and a valve opening electromagnet periodically, one of the valve opening electromagnet and the valve closing electromagnet is de-energized and thereafter the other electromagnet is de-energized at a time delayed by a predetermined time Toff. The alternate energization process is finished when the displaced position of a valve head which is detected by a displacement sensor has reached a predetermined position Vinit while the valve opening electromagnet is being energized. Thereafter, the valve opening electromagnet is continuously energized to seat the valve head in a closed position (initial position) from the time when the displaced position of the valve head has reached a predetermined position Vstart.

摘要： A controller for an electromagnetic actuator comprises a pair of spring acting in opposite directions, and an armature coupled to a mechanical element. The armature is connected to the springs and held in a neutral position given by the springs when the actuator is not activated. The actuator includes a pair of electromagnets for driving the armature between two end positions. The controller includes voltage application means for applying voltage to an electromagnet providing one end position for a first predetermined period so as to attract the armature to the end position. The controller also includes a peak current detector for detecting the peak of current flowing through the electromagnet in the first predetermined period. In accordance with the peak value, a decision means decides the application period of voltage that is to be applied to the electromagnet after the first application period has elapsed. Thus, the armature can make a stable seating at a controlled speed without generating substantial noise.

摘要： An electromagnetic valve controller estimates a dead time based on predetermined parameters. A dead time for the current cycle is determined based on the estimated dead time. The controller measures a dead time in the previous cycle. The controller determines a deviation between the dead time measured in the previous cycle and the dead time estimated in the previous cycle. The deviation is added to the dead time estimated in the current cycle to determine the dead time for the current cycle. The controller further determines a target de-energization timing indicating when to execute a valve timing command. The dead time determined for the current cycle is offset or subtracted from the target de-energization timing to determine an actual de-energization timing. An electromagnet of the valve is de-energized in accordance with the actual de-energization timing.

摘要： A valve timing control system for an internal combustion engine is provided which is capable of ensuring reliable holding of a valve by an actuator, and attaining energy saving by efficient operation of the actuator. The valve timing control system controls valve-closing timing of a valve opened by a cam provided on a camshaft, by temporarily holding the valve. A response delay of the actuator is predicted as a response delay prediction value. Output timing is set in which a drive signal for driving the actuator is output, according to the predicted response delay prediction value. Holding timing is controlled in which the valve is held by the actuator, by outputting the drive signal to the actuator, based on the set output timing.

摘要： An electromagnetic valve unit in an internal combustion engine is controlled by determining a difference between the output of a displacement sensor when a valve head is in an open position and the output of the displacement sensor when the valve head is in a closed position in each period of an opening and closing action of the valve head. The difference corresponds to a full displacement of the valve head between the open position and the closed position. The electromagnetic valve unit is also controlled by establishing, using the difference, a threshold for the output of the displacement sensor which corresponds to a predetermined displaced position of the valve head which is determined based on a proportion of the full displacement, and controlling energization of the valve-opening electromagnet and/or the valve-closing electromagnet depending on whether the output of the displacement sensor has reached the threshold or not upon the opening and closing action of the valve head immediately after the threshold is established.
