ANTI-PINCH LOGIC FOR DOOR OPENING ACTUATOR
First Claim
Patent Images
1. A vehicle door system, comprising:
- a vehicle structure having a door opening;
a door having a front edge portion that is rotatably mounted to the vehicle structure to close off the door opening when the door is in a closed position, the door including a rear edge portion that is opposite the front edge portion;
an anti-pinch sensor that is configured to detect a user'"'"'s hand if a user'"'"'s hand is positioned adjacent the door opening and/or adjacent an edge of the door;
an electrically-powered door actuator that can be actuated to partially open the door by shifting the door from a closed position to a partially open position to form a gap between the rear edge portion of the door and the vehicle structure such that a user can grasp the rear edge portion and pull the door to a fully open position, and wherein the electrically-powered door actuator can be actuated to shift the door from the fully open position towards the closed position;
a controller configured to;
1) cause the electrically-powered door actuator to generate a force tending to prevent the door from closing if the anti-pinch sensor detects a user'"'"'s hand; and
2) actuate the electrically-powered door actuator to shift the door from the fully open position towards the closed position.

Abstract
A vehicle door system includes a vehicle door and electrically-powered linear and rotary actuators. The vehicle door system also includes a pinch sensor. Upon receiving an open door command, a controller actuates the linear actuator and then actuates the rotary actuator to open the door. The controller also actuates the linear actuator to prevent closing of the door if the pinch-sensor detects an object in a door opening. The controller actuates the rotary actuator to close the door upon receiving a close door command.

9. A vehicle comprising:
-
a body having an opening; a movable door that selectively closes the opening; an electrically-powered actuator that opens and closes the door; an anti-pinch sensor configured to detect a user'"'"'s hand adjacent the door opening; and a controller that causes the electrically-powered actuator to generate a force that tends to prevent closing of the door when the anti-pinch sensor detects a user'"'"'s hand. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A vehicle door system comprising:
-
a door; electrically-powered linear and rotary actuators; a pinch sensor; and a controller configured to;
1) actuate the linear actuator followed by actuating the rotary actuator upon receiving an open door command;
2) actuate the linear actuator to prevent closing of the door if the pinch sensor detects a hand in a door opening; and
3) actuate the rotary actuator to close the door upon receiving a close door command. - View Dependent Claims (19, 20)
