In one embodiment, a pull wire and a hitch angle sensor assembly include a spacer fixed between a hitch ball and a mounting surface on a vehicle. An element is rotatably coupled with the spacer about a vertical axis defined by the hitch ball, and connecting member secures the element to a trailer. A hall sensor is coupled with the spacer and senses a magnetic portion of the element to determine a hitch angle between the vehicle and trailer. This and other embodiments of the hitch angle sensor assembly may be used independently or in combination with other hitch angle sensors or systems to estimate the pull wire and hitch angle between the vehicle and trailer, which may be advantageously used for operation of the vehicle with a trailer backup assist system.
