Abstract
An open/close body control system for a vehicle can stabilize outputs of a pair of electrically operated motors (M1, M2) which drive an open/close body for a vehicle. Speeds of the electrically-operated motor (M1, M2) are synchronously controlled such that predictive positions (XLt+1, XRt+1) of electrically-operated motor (M1, M2) after a lapse of a unit time gradually approach a target position (XTRG) calculated based on present positions (XLt, XRt) and a target speed (ΔXTRG) of the electrically-operated motors (M1, M2).
Claims5
A movable body control system for a vehicle comprising:
- at least two electrically-operated motors rotating drive shafts for supporting an open/close body by way of speed reduction mechanisms,
- a device indicating the rotational directions of motors,
- rotation sensors being provided to respective motors and generating pulse signals synchronized with the rotation of the motors,
- target speed setting means setting target speeds of respective motors,
- means for calculating positions and speeds of respective motors based on signals from the rotation sensors,
- means for calculating a target position after a lapse of a next unit time based on positions and the target speeds of respective motors,
- means for calculating predictive positions after a lapse of a next unit time based on positions and speeds of respective motors, and
- synchronous control means for determining output amounts of the motors by comparing the calculated target positions with the predictive positions.
A movable body control system for a vehicle comprising:
- at least a pair of electrically-operated motors for performing opening and closing operations of an open/close body for a vehicle,
- means for calculating a target position based on present positions of a pair of electrically operated motors,
- means for calculating predictive positions based on present positions and present speeds of a pair of electrically operated motors,
- means for calculating control positions based on signals from the predictive position calculating means and signals from target position calculating means, and
- synchronous control means for calculating speed control signals based on signals from control position calculating means and controlling speeds of a pair of electrically-operated motors based on the signals.
