1. A door assist system for a vehicle comprising:
- an actuator configured to control a position of a door about a hinge assembly;
an interference sensor configured to generate a detection signal indicating an obstruction in a plurality of detection regions along a radial extent of the door; and
a controller operating to;
control the actuator in response to the detection signal from the interference sensor, anddetect the obstruction at a plurality of thresholds based on the detection signal from each of the detection regions, wherein each of the thresholds controls a sensitivity of the controller indicating the obstruction in each of the detection regions and the sensitivity of the detection regions increases as the detection regions increase in proximity to the hinge assembly.

10. A vehicle door system comprising:
-
a plurality of proximity sensors disposed along at least one of a perimeter door seal and a perimeter door opening seal of a door, the proximity sensors configured to generate a detection signal, wherein each of the plurality of proximity sensors is configured to detect an obstruction in one of a plurality of detection regions positioned along a radial extent of the door relative to a hinge assembly; an actuator configured to control a position of the door; an angular position sensor configured to identify an angular position of the door; and a controller controlling the actuator based on the angular position of the door and the detection signal, wherein each of the detection regions comprises a sensitivity, and wherein a first region of the detection regions has a higher sensitivity than a second region of the detection regions, and the second region is further from the hinge assembly than the first region. - View Dependent Claims (11, 12, 13)
