摘要： PROBLEM TO BE SOLVED: To detect correctly battery short-circuit and disconnection when a driving transistor turns on, in a linear solenoid driving-gear which obtains prescribed displacement according to the magnitude of a driving current.
SOLUTION: A current flowing in the linear solenoid is detected. When the current value is at most a constant value, the battery short-circuit or the disconnection is detected. In order to evade erroneous detection at the time of load current ramping, mask time when the battery short-circuit or the disconnection is not detected is installed. For example, when a linear solenoid driving circuit is built in an electronic control device for an automobile, various adverse influence such as deterioration of operability and adverse influence on environment can be evaded.

摘要： PROBLEM TO BE SOLVED: To provide a position controller capable of reducing energy loss after convergence to a target position.
SOLUTION: In a worm gear 7 that is a power transmission device, efficiency wherein external force applied to a variable wing 1a becomes force moving a motor 2 is small as compared to efficiency wherein drive force of the motor 2 that is an actuator becomes force moving the variable wing 1a. A control means 5 controls a position of the variable wing 1a by the drive force of the motor, and keeps outputting the drive force balancing with the external force after arrival at the target position. The control means 5 restricts magnitude of the drive force of the motor after the variable wing 1a arrives at the target position.

摘要： PROBLEM TO BE SOLVED: To provide a positional change control device, for shortening a time before start of movement or solving a problem of blocking of the movement. SOLUTION: Driving force to be applied to a movable object is calculated by a normal method and is defined as a first driving force, and a second driving force is calculated by a different method. Before positional change is detected, the second driving force is added to the driving force firstly applied, or the movable object is driven by using the second driving force as an alternative for the former. After the positional change is detected, the movable object is driven by the first driving force. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To solve problems such as breakage of a component due to a high-speed collision of a turbocharger blade to a stopper and biting of a gear resulting in a failure of reverse-rotation because of irregular operation of a motor caused when a position detection value does not reach a target position during an encoder abnormal condition time in a position controller designed for driving the motor on the basis of positional information detected by a two-phase encoder for bringing an object to the target position or to a target angle.
SOLUTION: This position controller is provided with a means which determines that the encoder is in an abnormal condition and inhibits the operation of an actuator when the counter value of an encoder does not change more than two counts continuously for a fixed time in spite of driving of the actuator. When the encoder counter value does not change irregularly because of an abnormal condition of the encoder, this is detected and the motor driving is stopped. In this way, breakage of the component due to a high-speed collision of the turbocharger blade to the stopper or biting of the gear disabling reverse rotation can be prevented.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that a dynamic range becomes extremely narrow when occasion demands because a positioning error is integrated in case of controlling the position by motor drive, and to prevent an error of controlling the position by the motor by carrying out initialization and prevent the mechanical resistance of a motor position control device from increasing. SOLUTION: In a control method of a motor which opens or closes the passage hole of an intake air introduction path to a turbocharger of an automobile by means of movable vanes via an adjustable link by output of the rotary shaft, rotation of the motor is controlled to the halt position in such a direction as to close the movable vanes by the motor and to the halt position in such a direction as to open the movable vanes. The halt position is regarded as a motor operation criterion opening point. The motor is made to be operable between both the halt positions. Rotation of the motor is so controlled that the passage hole of the intake air introduction path may be opened at a target opening degree. COPYRIGHT: (C)2004,JPO&NCIPI
