Intelligent commutation pulse detection system to control electric D.C. motors used with automobile accessories |
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.
