Abstract
A system for controlling a displacement drive of a motor vehicle includes a manually operable actuator movable over a fixed stroke between a first end position and a second end position. The actuator is biased to a neutral position centrally located between the first and second end positions and provides a signal representative of position of the actuator. A controller receives the signal from the actuator and produces commands for a reversible DC electric motor of the displacement drive device. The commands vary speed of the drive motor based on the position of the actuator such that the speed of the drive motor is zero at the neutral position, increases in one direction as the actuator moves toward the first end position, and increases in the other direction as the actuator moves toward the second end position.
