Abstract
Methods, apparatus, systems and articles of manufacture are disclosed for payload estimation and fault detection using hitch integrated sensors. An example apparatus includes a pin orientation determiner to determine a first orientation of a first pin and a second orientation of a second pin, the first pin and the second pin disposed within a hitch and calculate a relative orientation of the first pin and the second pin based on the first orientation and the second orientation. The example apparatus further includes a hitch condition detector to determine if a physical change has occurred in the hitch by comparing the relative orientation to an installation orientation of the first pin and the second pin.
