Device for automatically controlling the closure of a sliding door for a vehicle

A device for automatically controlling the open-close of a vehicular sliding door comprising:

• a drive source,
• a slide door adapted to be open-close movable by means of a slide door open-close mechanism so supported as to be able to open and close along a side of a vehicle,
• a clutch means for intermittently transferring a drive force of the drive source to the slide door open-close mechanism,
• a vehicular slant judgement means for detecting a direction in which the slide door moves due to its weight, and for detecting a slant of the vehicle based on the detected direction, and for judging whether or not the vehicle is stopped on a level ground or an upward slope based on the detected slant;
• and
• a slide door control means for controlling the drive source and the clutch means, in order to control the drive force transferred to the slide door open-close mechanism,
• wherein the slide door control means controls the clutch means to release its connection between the drive source and the door open-close mechanism when the slide door is just before its full-open position while the slide door is full-open controlled, and controls the drive source and the clutch means in order to make the slide door stop just before its full-open position when the vehicular slant judgement means judges that the vehicle is stopped on a level ground or an upward slope.
