Abstract
A vehicle includes a liftgate system with a vertically-opening liftgate and a power actuator responsive to a user opening command for opening the liftgate to a variable opening height. The vehicle has an active sensor adapted to detect objects and their respective distances within a detection zone and a camera adapted to capture a search image with a field-of-view showing objects in the detection zone. In response to the user opening command, a controller 1) performs facial recognition on the search image to detect image locations containing a face of each respective person visible in the search image, 2) identifies distances for each respective person according to coincidence with the detected objects, 3) determines a user height according to the respective image location and distance of at least one respective person visible in the search image, and 4) sets the variable opening height in response to the user height.
