Manual to power controller for vehicle door moveable between open and closed positions
First Claim
1. A manual to power controller for a power-moveable object of an automotive vehicle, comprising:
- a direct-current electric motor for power-moving a power-moveable object mounted on an automotive vehicle;
detection means for detecting both a magnitude and a direction of an electromotive force induced in a coil of said motor;
said induced electromotive force resulting from a movement of said power-moveable object relative to a vehicle body with said motor de-energized; and
control means for rotating said motor in a desired rotational direction depending upon both the magnitude and the direction of said induced electromotive force to power move said power-moveable object with said motor energized.

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.
