Abstract
A vehicle is provided having an automatic swinging side door with an actuator for opening and closing the door. A controller has an algorithm for moving the actuator, a sensor for detecting an obstacle via contact with the door; and a sensor for detecting the obstacle without contact with the door. The controller interrupts movement of the door when the obstacle is detected. The door has a measurable and selectable opening angle. A hydraulic pump actuates the actuator using fluid pressure, and a hydraulic fuse monitors flow through a bypass valve to detect the contact. A method of opening a side-swinging vehicle door includes recording a door opening angle; detecting a door operating mode, opening the door when one mode is detected; closing the door when a second mode is detected; and opening the door to the recorded angle when a third mode is detected.
