  • Patent number: 11396942
    Abstract: A shift range control device includes a signal receiver, an abnormality monitor, and a drive controller. The signal receiver acquires an encoder signal from an encoder capable of outputting three or more phase encoder signals having different phases. The abnormality monitor monitors an abnormality of the encoder. The drive controller controls drive of a motor by switching an energized phase of a motor winding so that a rotation position of the motor becomes a target rotation position according to a target shift range. When the abnormality of the encoder is detected, the driver controller drives the motor by faulty phase identification control to identify a faulty phase that is a phase in which an abnormality of the encoder signal occurs, and a normal phase in which the encoder signal is normal.

  • Publication number: 20210301916
    Abstract: To provide such a shift apparatus that, at the time of electrically applying a reaction force to a rotation operation of the shift apparatus, a driver is not disabled to perform intended range switching when the application of the reaction force continues. If reaction force application means continues application of a reaction force for a predetermined time or more, reaction force application control means suppresses the application of the reaction force by the reaction force application means. When the reaction force application means has trouble, the driver may want to intentionally switch a range. In this case, the driver's intention to perform an operation is hindered. However, if application of a reaction force is suppressed when the application of the reaction force is continued for a predetermine time, it is possible to avoid the operation by the driver from being hindered.

  • Patent number: 11092237
    Abstract: A shift range control apparatus controls switching of a shift range by controlling driving of a motor, and includes a signal acquisition unit and a drive control unit. The signal acquisition unit acquires rotation angle signals output from a rotation angle sensor. The rotation angle signals respectively represents three or more phases different from each other. The drive control unit controls the driving of the motor to cause a rotational position of the motor to reach a target rotational position corresponding to a target shift range. The drive control unit changes from an energization pattern in a normal state to an energization pattern and continues the driving of the motor, in response to detecting a fault of the rotation angle signal during the switching of the shift range.

  • Publication number: 20200400232
    Abstract: A shift range control apparatus controls a shift range switching system that switches shift ranges by controlling driving of a motor. This control apparatus calculates a motor angle based on a motor rotation angle signal, acquires an output shaft signal based on a rotation position of an output shaft from an output shaft sensor, sets a target rotation angle based on a target shift range and the output shaft signal, and controls driving of the motor such that the motor angle becomes the target rotation angle. The control apparatus sets the target rotation angle to a target limit value, in response to the target rotation angle that is set based on the output shaft signal being a value at which rotation occurs that is further toward a back side in a rotation direction than the target limit value that is set based on shift ranges before and after switching.
