A control apparatus for a rear wheel steering system is provided to control the rear wheel steering system by calculating a target rear wheel steering angle using sensors included in a parking assist system. The control apparatus includes a first sensor and a second sensor spaced apart from each other and mounted on a rear portion of a vehicle, a determiner configured to determine whether a trailer is mounted at a rear side of the vehicle using the first sensor or the second sensor, and a controller configured to control the rear wheel steering system according to a target rear wheel steering angle calculated using the first and second sensors when it is determined that the trailer is mounted at the rear side of the vehicle.

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.

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 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.

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 multi-axle transport trailer having a plurality of axles includes a suspension comprising air bags associated with each axle, the air bags in communication with an air source, wherein air bags associated with different axles are capable of having different air pressures therein. The trailer further optionally includes a steering system associated with at least one axle, the axle including a tie rod connected between wheels on both ends of the axle, the steering system comprising cylinders configured to articulate the wheels, and a sensing device configured to monitor movement of the tie rod and facilitate actuating the cylinders to turn the wheels.

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.
