A method of mitigating false warning on a vehicle having at least one side radar sensor, a steering wheel and a steering angle sensor comprises the at least one side radar sensor not detecting an object. The steering angle sensor detects that the steering wheel has moved such that the vehicle and the trailer are out of line. Warning arising from the at least one side radar sensor is suspended.

A vehicular trailering assist system includes a camera and an image processor operable to process image data captured by the camera. The vehicular trailering assist system iteratively predicts a plurality of predicted trailer angles based on a corresponding plurality of potential trailer beam lengths ranging between an upper dimension above a baseline trailer beam length and a lower dimension below the baseline trailer beam length and selects a trailer angle from the plurality of predicted trailer angles that least deviates from a current trailer angle determined via processing by the image processor of image data captured by the camera. The potential trailer beam length that corresponds to the selected trailer angle that least deviates from the determined current trailer angle is used in determining trailer angles for that trailer during future drives of the vehicle when towing that particular trailer.

A control system of a self-driving tractor can access sensor data to determine a set of trailer configuration parameters of a cargo trailer coupled to the self-driving tractor. Based on the set of trailer configuration parameters, the control system can configure a motion planning model for autonomously controlling the acceleration, braking, and steering systems of the tractor.

A trailer assembly with improved lateral support structure and steering system control of the axial wheels on a front elongated trailer and a rear elongated trailer to remain in a collinear following configuration to carry elongated loads extending over the extended lengths of the combination of the front elongated trailer and the rear elongated trailer and allow ready turning control.

The turning radius of a differentially steered vehicle towing a trailer is controlled when turning so that its turning radius is greater than a minimum allowable turning radius. The turning radius may be autonomously adjusted using a controller to monitor the instantaneous rotational speed differential between the driven wheels and increase or decrease the relative speed between the wheels when the instantaneous rotational speed differential exceeds a threshold rotational speed differential, indicating a turn which is too tight. Alternately, the turning radius may be controlled by the vehicle's operator, who receives a signal from the controller indicating that the vehicle's turning radius is less than the minimum allowable. The operator may then take action to enlarge the turning radius using manual controls.

A coupling device of the type envisaged between a first vehicle (A) with at least two axes and a second vehicle (B) with at least two axes with the first vehicle (A) arranged to precede the second vehicle (B), in particular for the application to convoys of automatically guided vehicles, includes a hinge coupling section associated with the first vehicle (A) and a drawbar section associated with the second vehicle (B), connected to each other with the possibility of rotation through the relative distal sections. The drawbar section has an arc-shaped guide arranged horizontally in front of the second vehicle (B) to extend from the right side to the left side thereof, a slider sliding along the arc-shaped guide and a telescopic arm integral with one end of the slider and rotatably connected to the other end to the coupling section. The coupling device also advantageously include a steering assistance mechanism suitable for a redundancy of the steering members (S) of the second vehicle (B) by setting a steering angle which is a function of the position of the slider along the arc-shaped guide. The coupling device allows the automatic guide system to control the position and trajectories of the vehicles without any substantial exchange of forces through the device and enters into operation to allow the safe stop of the convoy when there are anomalies in the operation of the automatic guide system.
