Abstract
An automotive electric motor speed control system may include at least one electric motor adapted to cause a moveable element to move, a DC/DC power converter configured to output a voltage to the at least one electric motor that increases to a desired value and subsequently decreases to control the movement of the moveable element, and a controller configured to control the rate of voltage increase and voltage decrease output by the converter.
Claims18
An automotive seat system comprising:
- a moveable vehicle seat;
- at least one electric motor adapted to cause the seat to move;
- a DC/DC power converter;
- at least one switch electrically connected with the at least one motor and the converter;
- and
- a controller in communication with the converter, the converter configured to output a voltage ramp, under the command of the controller, to the at least one motor to control the acceleration or deceleration of the seat.
