1. An interference sensor for a vehicle door comprising:
- a door opening seal;
an array of proximity sensors forming a portion of the seal, each of the proximity sensors configured to detect an obstruction in one of a plurality of sensory regions comprising a first sensory region comprising a first sensory threshold and a second sensory region comprising a second sensory threshold, the sensory regions extending from a hinge assembly interconnecting the vehicle door to a vehicle body, wherein the first sensory region is located closer to the hinge assembly than the second sensory region and the first sensory threshold is lower than the second sensory threshold; and
a processor in communication with the proximity sensors and configured to detect the obstruction of a motion of the vehicle door in the sensory regions, wherein the processor is configured to;
receive a detection signal from the array of proximity sensors,detect the obstruction in response to the detection signal exceeding at least one of the first sensory threshold and the second sensory threshold, andoutput a control signal in response to the detection of the obstruction, the control signal being configured to control the motion of the vehicle door.

Abstract
A door assist system for a vehicle is disclosed. The system comprises an actuator configured to control a position of the door about a hinge assembly. An interference sensor forms a portion of a door opening seal and is configured to detect an obstruction in a plurality of detection regions. The system further comprises a controller configured to control the actuator in response to a detection signal from the interference sensor.
