    摘要： In a motor-driven shift position switching device, when the difference between a target position and the rotation position of a rotor has become smaller than a prescribed value in a motor feedback control, a transition is made to a deceleration control. A phase lead correction amount for correcting the phase lead of the current supply phase with respect to the rotor rotation phase is set in accordance with the rotor rotation speed. Thus, proper braking force suitable for the rotor rotation speed is exerted on the rotor and the rotor can be decelerated smoothly as it approaches the target position. Further, in the period when the current supply to the motor is kept off, the shift position switching determination ranges are set wider than in the period when the current supply to the motor is on.

    摘要： In an automatic transmission position control by a motor, it is determined whether the present instant belongs to a starting period, that is, the present instant is immediately after resetting of a control unit or application of power to it. If it is the starting period, an actual shift position that is detected from an output of an output shaft sensor for detecting a rotation position of a motor is set as an instructed shift position. With this measure, even if the control unit is reset for a certain reason while the vehicle is running, the instructed shift position is not changed in association with the resetting. This prevents trouble that the shift position is switched contrary to the intention of the driver, whereby the reliability of a position switching control can be increased.

    摘要翻译： 在由电动机进行的自动变速器位置控制中，判断当前时刻是属于起动时间段，即当前时刻是在控制单元重新设置之后立即还是施加电力。 如果是开始期间，则将从电动机的旋转位置检测出的输出轴传感器的输出检测出的实际换档位置设定为指示档位。 通过该措施，即使在车辆行驶时由于某种原因控制单元被复位，指示的换档位置也不会与复位相关联地改变。 这防止了与驾驶员的意图相反地切换换档位置的故障，从而可以提高位置切换控制的可靠性。

    摘要： A shift control system rotates an actuator to allow a wall of a detent plate and a roller of a detent spring to contact each other and then detects the position of contact so as to detect the position of the wall of the detent plate. After the wall position is determined, the actuator is driven in the direction opposite to the wall until the actuator reaches a position located before the wall position and distant therefrom by a predetermined amount, in order to cancel flexure or extension of the detent spring that is caused when the detent spring is pushed against the wall of the detent plate. Accordingly, such a situation where the shift position is moved by the recovery force of the detent spring can be avoided.

    摘要： A P-ECU controls an actuator which drives a shift control mechanism. An encoder signal acquisition unit acquires signals output from an encoder which detects a rotational angle of the actuator. A counter calculates a count value from the output signals of the encoder. An energization control unit controls energization to the actuator. A first phase-matching unit uses the Z-phase signal of the encoder to match the count value with energized phases so as to find a correspondence therebetween and a second phase-matching unit matches the count value with energized phases to find a correspondence therebetween without using the Z-phase signal of the encoder. If the first phase-matching unit detects an abnormality of the encoder, the second phase-matching unit subsequently performs phase matching.

    摘要： Presence/absence of a failure in a feedback control system of a motor is monitored. When a failure is detected in the feedback control system, the motor is driven by switching to an open-loop control. During the open-loop control, the motor is rotated by sequentially switching the motor current supply phase without feeding back encoder count information. The position count is incremented or decremented every time the current supply phase is switched. When the position count has reached a target count, it is determined that the rotor has reached a target position, whereupon the open-loop control is finished.
