Abstract
A manual to power controller suitable for a vehicle door such as preferably a sliding door comprises a direct-current electric motor for power-moving the vehicle door, and at least one door movement detection circuit for detecting both a magnitude and a direction of an electromotive force induced in a coil of the DC motor. The induced electromotive force results from a movement of the vehicle door relative to the vehicle body with the motor de-energized. Also provided is a microcomputer for rotatively controlling the motor in a desired rotational direction depending upon both the magnitude and the direction of the induced electromotive force to power move the vehicle door with the motor energized.
