A system according to the present disclosure includes an estimated hitch angle module, a measured hitch angle module, a corrected hitch angle module, and at least one of a driver assist module and an actuator control module. The estimated hitch angle module estimates a hitch angle, which is an angle between a longitudinal axis of a vehicle and a longitudinal axis of a trailer that is attached to the vehicle. The measured hitch angle module determines a measured hitch angle based on an input from a sensor. The corrected hitch angle module determines a corrected hitch angle based on the estimated and measured hitch angles. The driver assist module controls a user interface device to assist a driver of the vehicle based on the corrected hitch angle. The actuator control module controls an actuator of at least one of the vehicle and the trailer based on the corrected hitch angle.

In a control system for steering a combination with at least one electronic control unit, with a sensor apparatus for capturing the bend angle of the combination and with a display unit, the control unit has a memory region for storing a maximum reversible bend angle, a memory region for storing an upper bend angle change threshold value, and/or a memory region for storing a left hand bend angle range and a right hand bend angle range with reference to the zero line corresponding to a straight combination. A functional unit is designed to output a recommended action for moving forward on the display unit and/or for carrying out an autonomously executed forward movement, when the presence of at least one defined situation in relation to the values related to the bend angle stored in the memory region is ascertained through evaluation of the sensor apparatus.

The present invention relates to entering data into a trailer backup guidance system. In particular, the present invention relates to storing data in the components of a trailer backup guidance system corresponding to a plurality of trailer and vehicle combinations to better facilitate sharing those components across a plurality of trailers and vehicles.

A trailer has a frame having frame-members configured to support a container, at least a pair of traction devices rotatably mounted on the frame, and a tongue configured to be mounted on a transportation device or an implement being towed by a transportation device. The frame-members may have a three-point mount configured to support a container. The container may be configured to be interchangeable with another container. The container may be an element of a seeding apparatus, the seeding apparatus mountable on the frame-members of the frame. The trailer may have a steering mechanism for the traction devices, and may be convertible between steerable and non-steerable modes. The steering mechanism may be guidance controlled. A transverse distance between the traction devices may be adjustable and/or height of the frame in relation to the ground may be adjustable. The trailer provides greater flexibility of operation under a greater variety of conditions.

A method for controlling a wheel axle assembly of a vehicle. The vehicle comprises a vehicle body with a longitudinal axis extending in a longitudinal direction, a transversal axis extending in a transversal direction and a vertical axis extending in a vertical direction. The longitudinal axis, the transversal axis and the vertical axis are perpendicular to each other. The longitudinal direction corresponds to an intended direction of travel of the vehicle and the vertical direction being parallel to a vertical line when the vehicle is positioned on a flat horizontally extending surface. The vehicle body comprises a vehicle body centre plane extending along the longitudinal axis and the vertical axis and separating the vehicle body into two body halves.

Disclosed is a trailer including a bed portion. The bed portion includes a deck, a front extension, and a rear extension. The deck has a first end and a second end. The front extension is slideably engaged with the first end of the deck, and the rear extension is slideably engaged with the second end of the deck. The trailer is a double stretch trailer that is extendable from both ends of the deck. A towing system including a cab and the trailer is also disclosed.

A self-steering bogie for an elongate road vehicle having at least a first axle assembly at the front end of the vehicle and at least one trailing axle assembly disposed on the vehicle behind said first axle assembly. The trailing axle assembly is a set of tandem axles with associated wheels disposed below a structural frame of the vehicle, the bogie comprising a rotatable sub-frame borne on the set of tandem axles which supports the vehicle by means of a load bearing turntable. A rotational restraint assembly is mounted on the turntable and which in part interconnects the sub-frame, the structural frame and an upper portion of the turntable, the rotational restraint assembly having a plurality of compression air springs. The elongate road vehicle could be a truck and semitrailer where the trailing axle assembly is on the semitrailer, or a vehicle such as a bus.

A rear-wheel steering system suitable for use on an automated vehicle includes an object-detector, and actuator, and a controller. The object-detector is used to detect an object proximate to a host-vehicle. The actuator is used to adjust a rear-steering-angle of rear-wheels of the host-vehicle. The controller is in communication with the object-detector and the actuator. The controller is configured to determine a location of the object relative to the host-vehicle based on information from the object-detector, and operate the actuator to avoid the object when the host-vehicle moves.
