An image processor is operable to process image data captured by the camera to determine if an object is present in the region that is swept by the hatch to determine if the hatch may collide with the detected object when the hatch is being opened/closed. Responsive to determination of a potential collision of the hatch with a detected object, the vehicle hatch control system may stop movement of the hatch and/or may move the hatch to a holding position. ## Claims ### Claim 1 A vehicle hatch control system, said vehicle hatch control system comprising: a camera disposed at a rear portion of a vehicle equipped with said vehicle hatch control system, said camera having a rearward field of view that encompasses a region at the rear of the equipped vehicle that is swept by a hatch of the equipped vehicle as the hatch is opened and closed via a powered hatch opening/closing system of the equipped vehicle;

an image processor operable to process image data captured by said camera to determine if an object is present in the region that is swept by the hatch to determine if the hatch may collide with the detected object when the hatch is being opened and/or closed; wherein said hatch comprises one of a liftgate of the equipped vehicle, a deck lid of the equipped vehicle and a rear door of the equipped vehicle; wherein, responsive to determination of a potential collision of the hatch with a detected object in the path of travel of the hatch when the hatch is closing, said vehicle hatch control system is operable to position the hatch at a partially open position; and wherein said vehicle hatch control system is operable to generally maintain the hatch at the partially open position, and wherein said vehicle hatch control system is operable to generally maintain the hatch at the partially open position when the equipped vehicle is being driven. ### Claim 15 (depends on 14) The vehicle hatch control system of claim 14, wherein said vehicle hatch control system is operable to position the hatch at the partially open position in response to a user input. ### Claim 16 (depends on 15) The vehicle hatch control system of claim 15, wherein said user input comprises identification of a gesture of the user. ### Claim 17 A vehicle hatch control system, said vehicle hatch control system comprising: a camera disposed at a rear portion of a vehicle equipped with said vehicle hatch control system, said camera having a field of view that encompasses a rear storage region of the equipped vehicle that is enclosed by a hatch of the equipped vehicle when the hatch is closed; wherein said hatch comprises one of a liftgate of the equipped vehicle, a deck lid of the equipped vehicle and a rear door of the equipped vehicle; an image processor operable to process image data captured by said camera to determine if an object is present in the rear storage region and to determine if the detected object would contact the hatch as the hatch is moved from an opened position to a fully closed position; wherein, responsive to the determination of the detected object in the rear storage region and the potential contact of the hatch with the detected object, said vehicle hatch control system is operable to move the hatch to a partially open position where a gap is established between the hatch and the detected object; and wherein said vehicle hatch control system is operable to control the hatch to generally maintain the gap between the hatch and the detected object when the equipped vehicle is being driven. ### Claim 18 (depends on 17) The vehicle hatch control system of claim 17, wherein said vehicle hatch control system moves the hatch and establishes the gap responsive to an input, and wherein said input comprises at least one of (i) actuation of a powered hatch opening/closing system, (ii) manual closing of the hatch, (iii) a user input and (iv) identification of a gesture of a user at the rear of the equipped vehicle. ### Claim 19 (depends on 17) The vehicle hatch control system of claim 17, wherein said image processor is operable to determine if an object is present in a region that is swept by the hatch as the hatch is opening to determine if the opening hatch may collide with an exterior object when the hatch is being opened, and wherein, responsive to determination of a potential collision of the hatch with a detected exterior object, said vehicle hatch control system is operable to stop movement of the opening hatch so that an opening gap is established between the hatch and the detected exterior object. ### Claim 20 (depends on 19) The vehicle hatch control system of claim 19, wherein said vehicle hatch control system is operable to at least one of (i) adjust the position of the hatch to maintain the opening gap when a height of the vehicle changes and (ii) continue opening movement of the hatch responsive to a determination that the path of travel of the hatch is clear.
