  • Gear shifter
    Patent number: 10145465
    Abstract: A gear shifter performs an abutment learning, having a reference value learner that sets a reference value of a position signal when abutting a drive object to a stopper, and reduces warpage by (i) an all phase power supply supplying to the electric current to all of the plural phase coils of the direct current motor, and (ii) by reducing an amount of the electric current supplied to the coils, and by decreasing a pressing force of the drive object pressing the drive object against the stopper. The reference value determined at a warpage diminish time enables a reduction of variation of the reference value due to an influence of the warpage, thereby setting a robust reference value to account for an environmental condition such as a temperature change, for an accurate shift operation of the gear shifter.

  • Shift position switching device
    Patent number: 10144282
    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.

  • Shift range control apparatus
    Patent number: 10138999
    Abstract: A control circuit switches over a shift range by controlling driving of a motor to rotationally drive a detent plate. A current detection circuit detects a current value corresponding to a driving current supplied to drive the motor. A current increase check part performs check processing to check whether the current value detected by the current detection circuit has increased. A motor rotation stop part stops rotation of the motor when the current increase check part determines that the current has increased. A reverse driving part reverses the rotation direction of the motor and rotationally drives the motor after stopping of the motor by the motor rotation stop part.

  • SHIFT RANGE CONTROLLER
    Publication number: 20180283545
    Abstract: A shift range controller includes a target speed setter that sets a target motor speed for a motor based on an angle deviation between a current rotation position of the motor and a target rotation position based on a requested shift range. A requested duty calculator calculates a requested duty as a drive control amount for driving the motor based on the target motor speed. The target speed setter receives a feedback of the requested duty, and changes the target motor speed at a deceleration time based on the feedback of the requested duty. By changing the target motor speed based on the requested duty, the target motor speed is optimized for responding to impediment-causing factors such as temperature and friction. In such manner, the shift range switching responsiveness is improved.

  • Shift range control apparatus
    Patent number: 10088043
    Abstract: A PWM control part rotationally drives a motor based on a PWM control value. A rotation speed control part controls a rotation speed of the motor. A rotation angle detection part detects a rotation angle of the motor. A reference position learning part controls the motor to rotate at a constant rotation speed until a detent plate stops at a limit position of a movable range and learns a reference position of the motor. A current detection circuit detects a current value corresponding to a driving current. A current limitation part limits a current supplied to the motor. A PWM control value limitation part controls the PMW control value to be equal to or smaller than a PWM limitation value, which is a predetermined value. A relation check part checks whether a relation between a current value detected by the current detection circuit and the PWM control value is inappropriate.

  • Range-switching control device
    Patent number: 10060527
    Abstract: During changing of a shift range (for example, from P-range to NotP-range), an SBW-ECU determines whether it is in a range-change delay condition (a switching completion time of the shift range is delayed than a normal switching completion time). When it is determined that it is in the range-change delay condition, it is determined whether a target range should be changed to a safer range (for example, P-range). As a result, when it is determined that the target range should be changed to the safer range, the target range is changed to the safer range. Thereby, even if a driver determines that the shift range cannot be changed before the switching completion of the shift range and the driver gets off the vehicle, the shift range can be changed to the safer range (P-range).

  • Motor controller having a power-saving control, and a motor control system including the motor controller
    Patent number: 9843277
    Abstract: A motor controller that is configured to switch power supply phases of the motor, to perform a limit-position abutment control by rotating the motor to a movable limit of a movable range of the rotation object to learn a reference position of the motor, perform a power-saving return control afterwards, in which a power supply to the motor is stopped, thereby returning a rotation position of the motor toward a target rotation position, and stop the rotation of the motor by simultaneously supplying power to a preset phase of the motor, when the rotation position of the motor reaches the target rotation position. In such manner, the power consumption as well as the heat generation of the motor are reduced for returning the rotation position of the motor to a preset rotation position after the abutment control of the motor.

  • Range switchover apparatus
    Patent number: 9806664
    Abstract: When electric power supply is started, an initial driving operation is performed to switch over a power supply phase of a motor in open-loop control. Initial learning processing is performed to learn a phase deviation correction value for the power supply phase relative to a count value of a pulse signal of an encoder. As a restraint caused by a shape of a detent mechanism, the motor need be rotationally driven so that a detent lever does not move in a negative direction beyond a bottom position of a P-range in the initial driving operation. In a case of performing the initial learning processing in the P-range in consideration of this restraint, the initial learning processing is performed by setting a rotation direction of the motor.
