    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： 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.

    摘要： Before an amount of play in a rotation transmitting system is learned, for selecting a gear range, an overshooting control process is performed to cause the angular displacement of a motor to overshoot a target gear range position and then reverse the electric motor. The angular displacement of the motor overshoots the target get gear range position by an overshooting amount that is identical to am amount by which the electric motor is reversed. The overshooting amount is set to a maximum value of a designed amount of play in the rotation transmitting system After the amount of play is learned, for selecting a gear range, a target count is established in view of the learned amount of play and the direction in which the motor rotates, and the motor is stopped at a position where an encoder pulse count coincides with the target count without performing the overshooting control process.
