A trailer angle measurement assembly that measures an angle of a trailer relative to a tractor includes a mounting base, an armature, a roller wheel and a rotary encoder. The mounting base is configured to be selectively coupled to the trailer. The armature is rotatable coupled to the mounting base around a pivot. The roller wheel is rotatably coupled to the armature and is positioned for rotatable engagement with the trailer. The rotary encoder measures rotation of the roller wheel and generates a signal based on the measured rotation indicative of an angular position of the trailer relative to the tractor.

A wheel-end assembly for a vehicle enabling the direct measurement of the wheel-end position. The wheel-end assembly includes a knuckle having a kingpin bore and a kingpin disposed within the kingpin bore. The knuckle is at least partially rotatable about a longitudinal axis of the kingpin. A knuckle cap assembly is coupled with the kingpin bore adjacent to an end of the kingpin. In addition, a sensor is coupled with the knuckle cap assembly which measures a position of the kingpin relative to the sensor.

A trailer angle identification system includes an imaging device configured to capture an image. A controller is configured to receive steering angle data corresponding to a steering angle of a vehicle, receive vehicle speed data corresponding to a vehicle speed, and estimate an angle of the trailer relative to the vehicle by processing the image, the steering angle data, and the vehicle speed data in at least one neural network.

The present document relates to a steering sensor assembly comprising an axle housing and a kingpin rotatably mounted on the axle housing, wherein the kingpin features a through hole extending through the kingpin. The steering sensor assembly further comprises a mounting member connected to the axle housing and at least partially disposed in the through hole extending through the kingpin, and a steering sensor comprising a first sensor portion coupled to the kingpin and a second sensor portion coupled to the mounting member.

An apparatus for measuring the steering angle of a wheel assembly including a suspended wheel mount and at least one suspension arm, the apparatus including a reference bracket, a rotating bracket and an angle sensor, the reference bracket and the rotating bracket each respectively including a measurement end and a mounting end, wherein the measurement ends of the reference and rotating brackets are rotatably coupled about a rotation coupling point such that the brackets can rotate with respect to one another, wherein the mounting end of the rotating bracket is coupled with the suspended wheel mount and the mounting end of the reference bracket is coupled with the suspension arm, and wherein the mounting end of the reference bracket is positioned on a plane defined by a steering axis of the suspend-wheel mount and a rotation axis between the suspension arm and the suspended wheel mount.

A vehicle system for determining a road wheel angle of a vehicle includes sensors configured to detect vehicle parameters including at least a steering rack load on a steering rack of the vehicle, and a control module in communication with the sensors. The control module is configured to calculate a kingpin torque based on the sensed steering rack load and a wheel-to-body displacement of the vehicle, determine a roll steer angle based on the wheel-to-body displacement of the vehicle, determine a road wheel angle of the vehicle based on the roll steer angle and the kingpin torque, and generate a signal indicative of the road wheel angle to control at least one vehicle control system. Other example vehicle systems and methods for determining a road wheel angle of a vehicle are also disclosed.

A kink angle sensor arrangement for a vehicle combination includes a connecting element with a longitudinal center axis, a first articulation piece on the connecting element, and a second articulation piece for connection to a towing or towed vehicle. The first articulation piece is configured to be mounted rotatably on the second articulation piece such that the first articulation piece can twist about a second axis of rotation with respect to the second articulation piece. The arrangement includes a first coupling piece configured to be detachably mechanically connected to a second coupling piece to prevent twisting of the first coupling piece with respect to the second coupling piece, and a sensor system configured to detect a rotated position and/or a rotational movement of the first articulation piece, and to generate and output a sensor signal characterizing the rotated position and/or the rotational movement of the first articulation piece.
