Abstract

An automotive vehicle includes a closure frame defining an opening, and a closure for selectively covering the opening. The closure has a plurality of positions including a closed position, an open position, and an intermediate position between the closed position and the open position. The vehicle also includes an actuator configured to move the closure among the plurality of positions. The vehicle additionally includes an optical sensor disposed proximate the closure. The vehicle further includes a controller. The controller is configured to automatically control the actuator to move the closure from the closed position to the open position in response to a closure open request and no feature being detected by the optical sensor, and to automatically control the actuator to move the closure from the closed position to the intermediate position in response to a closure open request and a feature being detected by the optical sensor.

Claims

1. An automotive vehicle comprising:

a closure frame defining an opening to the vehicle;

a closure arranged relative the closure frame to selectively cover the opening, the closure having a plurality of positions including a closed position, an open position, and an intermediate position between the closed position and the open position;

an actuator configured to move the closure among the plurality of positions;

at least one optical sensor disposed proximate the closure and configured to sense a region proximate the closure; and

a controller configured to automatically control the actuator to move the closure from the closed position to the open position in response to a closure open request and no object or person being detected by the optical sensor, and to automatically control the actuator to move the closure from the closed position to the intermediate position in response to a closure open request and an object or person being detected by the optical sensor.

2. The automotive vehicle of claim 1, wherein the controller is further configured to determine a feature height associated with the object or person, and wherein a location of the intermediate position relative to the open position and the closed position is based on the feature height.

3. The automotive vehicle of claim 2, wherein the controller is further configured to classify the object or person as a person, and wherein in response to the object or person being classified as a person, the location of the intermediate position corresponds to a closure height being a predefined distance above the feature height.

4. The automotive vehicle of claim 2, wherein the controller is further configured to classify the object or person as an object above the vehicle, and wherein in response to the object or person being classified as an object above the vehicle, the location of the intermediate position corresponds to a closure height being a predefined distance below the object.

5. The automotive vehicle of claim 1, wherein the optical sensor includes a backup video camera disposed on the closure.
