Abstract: A shift position switching device for shifting gears in association with a shift position. The device includes a shift mechanism switching between shift positions using a drive power of a motor, an encoder outputting pulse signals in sync with a rotation of the motor, and a controller rotating the motor to a target rotation position corresponding to an intended gear. The controller rotates the motor toward a dead-end on a first shift position side of the shift mechanism while observing a motor rotation speed or an acceleration of rotation of the motor based on the outputted pulse signals of the encoder. Also, the controller learns, as a reference position on the first shift position side, a first rotation position of the motor.

Abstract: An output shaft includes a shaft hole with which a shaft is fittable, rotates by torque output from a motor, and outputs torque to the shaft. A magnet holder includes a holder hole with which the shaft is fittable and is rotatable together with the shaft. A magnet is disposed on the magnet holder. An angle sensor is capable of detecting magnetic flux from the magnet and outputs a signal corresponding to a rotation angle of the magnet holder. A play amount between the shaft and the shaft hole is set to a first predetermined value or larger. A play amount between the shaft and the holder hole is set to a second predetermined value or smaller.

Abstract: A motor control apparatus includes a motor that rotates a controlled object, an encoder that outputs a pulse signal in synchronization with a rotation of the motor, and a control section that performs a feedback control so as to rotate the motor to the target rotational position. The control section includes a stopping and holding control portion. The stopping and holding control portion performs a stopping and holding process in which the stopping and holding control portion supplies electric current to the motor so as to stop and hold the motor for a current-supply holding time. The stopping and holding control portion sets the current-supply holding time on the basis of a rotation speed of the motor just before the stopping and holding process.

Abstract: An accelerator device includes a pedal lever, a reaction force adjuster and a controller. The pedal lever operates according to a stepping operation. The reaction force adjuster is driven by an actuator, and is capable of adjusting a reaction force that is a force in a direction of pushing back the pedal lever. The controller includes a target operation amount setting unit and a drive control unit. The target operation amount setting unit sets a target operation amount, which is an operation amount of the pedal lever according to a vehicle speed. The drive control unit controls a drive of the actuator. The controller controls the reaction force according to the target operation amount so that the operation amount of the pedal lever is within a target range when switching from an automatic drive to a manual drive.

Abstract: A rotary actuator used in a shift-by-wire system of a vehicle includes: a motor; an output shaft arranged parallel to a rotation shaft of the motor; and a deceleration mechanism that decelerates rotation of the motor and transmits it to the output shaft. The deceleration mechanism includes a drive gear provided over a rotation axis of the rotation shaft and a driven gear provided over a rotation axis of the output shaft to mesh with the drive gear. The driven gear is a separate member from the output shaft and is loosely fitted to the output shaft.

Abstract: A motor control apparatus that controls rotation of a rotor of an electric motor powered from an electric power source includes a learning portion that executes an initial drive learning process, and a controller that executes a normal drive operation to sequentially change an exciting phase of the electric motor based on a count value of a counter which is corrected by a correcting portion such that the rotor is rotated to a target position after an initial drive operation is finished. The learning portion re-executes the initial drive learning process after a predetermined condition is satisfied, when the initial drive learning process is failed.

Abstract: A SBW-ECU prohibits driving of an electric motor by turning off power supply to the motor by a drive prohibition device, when a diagnosis part of a by-wire control circuit determines that a shift-by-wire system is abnormal or a monitor circuit determines that the by-wire control circuit is abnormal. In this case, the motor is stopped from rotating by execution of power supply phase fixation processing, by which a power supply phase of the motor is fixed without switchover, when the motor is driven to rotate at the time of determination of abnormality of the shift-by-wire system. Then the prohibition device prohibits driving of the motor by stopping the power supply to the motor.
