Abstract:
Methods and apparatus are disclosed for vision-based determining of trailer presence. An example vehicle includes a camera to capture a plurality of frames. The example vehicle also includes a controller to calculate feature descriptors for a set of features identified in a first frame, compute respective match magnitudes between the feature descriptors of the first frame and for a second frame, calculate respective feature scores for each feature of the set of features, and determine if a trailer is present by comparing a feature score of a feature to a threshold.

Claim (Index 10):
The vehicle of  claim 9 , wherein the controller is to generate an indeterminate signal when the reference features do not satisfy the first set of thresholds and do not satisfy the second set of thresholds.
