1. A detection system for detecting an object in relation to a movable door, said detection system comprising:
- an object detection sensor located on a movable door for sensing an object within a sensing zone, said object detection sensor being adjustable to vary the size of the sensing zone;
a door position sensor for sensing position of the door relative to at least one of open and closed door positions; and
a controller operable coupled to the object detection sensor and the door position sensor and adapted to adjust the sensor to vary the size of the sensing zone of the object detection sensor as a function of the sensed door position.

Abstract
A non-contact detection system and method for detecting obstructions in relation to a powered door on a vehicle such that contact with the door may be prevented. The detection system includes an object detection sensor located on the powered door for sensing an object within an adjustable sensing zone. A door position sensor senses position of the door relative to at least one of an open and closed door position. A controller adjusts the sensing zone of the object detection sensor as a function of the sensed door position.

10. An object detection system for detecting an object in relation to a movable powered door on a vehicle, said detection system comprising:
-
an object detection sensor located on a movable powered door on a vehicle for sensing an object within a sensing zone, said object detection sensor having a sensitivity that is adjustable to vary the size of the sensing zone; a door position sensor for sensing position of the movable powered door; and a controller operably coupled to the object detection sensor and the door position sensor and including means for adjusting the sensitivity of the object detection sensor as a function of the sensed door position to thereby vary the size of the sensing zone, wherein the controller further changes movement of the powered door when an object is sensed in the sensing zone. - View Dependent Claims (11, 12, 14, 15, 16, 17)

18. A method of detecting an object in relation to a movable door, said method comprising the steps of:
-
locating a object detection sensor on the movable door, said object detection sensor having a sensing zone and being adjustable to vary the size of the sensing zone; sensing position of a movable door relative to at least one of open and closed door positions; adjusting the sensor to determine the size of the sensing zone as a function of the sensed door position to create an adjusted sensing zone; and sensing the presence of an object within the adjusted sensing zone. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
