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： A control system for use with a bidirectional motor connected to a motorized vehicle accessory to move the accessory a distance from a first position to a second position. The control system includes a detector responsive to control signals emitted from the motor during rotation, where the control signals indicate the amount of motor rotation. The control system also includes a memory that stores information used to represent the position of the accessory. Additionally, this control system includes a controller responsive to the memory and the detector. The controller provides an output signal to operate the motor based on the distance between a first position and a second position of the accessory as well as control signals that indicate the amount of motor rotation. The controller includes an adjustment routine that determines a correction factor that is applied to the output signal to compensate for inaccuracies in control signal detection.
