A coupling device for attaching a power lift of a tractor to an attachment includes a link mounting region having coupling units for the articulation of an upper link and two lower links of the power lift, and an apparatus mounting region for fixing the attachment. A coupling unit assigned to the upper link is movable in a translatory manner in a vertical direction running perpendicular to a transverse direction. The coupling units are movably disposed on a device base of the coupling device, and the coupling units assigned to the two lower links are movable in a translatory manner in the transverse direction.

A system for assisting in aligning a vehicle for hitching with a trailer includes an imaging system, a vehicle control system including at least one vehicle sensor, and a controller. The controller controls the vehicle using the vehicle control system to move the vehicle into an aligned position, where a hitch ball on the vehicle is aligned with the coupler, including monitoring a signal from the vehicle sensor and tracking a position of the coupler relative to the hitch ball in image data. When the signal indicates an unintended stopped vehicle state, the controller determines a distance from the hitch ball to the coupler. If the distance is above a predetermined threshold, the controller controls the vehicle control system to cause the vehicle to move. If the distance is below the predetermined threshold, the controller indicates the unintended stopped vehicle state to a driver of the vehicle.

A towing assist device includes an imaging device configured to capture a rear area from a towed vehicle when a towing vehicle moves backward, the towed vehicle being connected to the towing vehicle via a connector; a monitor device including a display screen configured to display a captured image which is captured by the imaging device, a touch screen function for detecting a touch position to the display screen; and a controller that is connected to the imaging device and the monitor device and is configured to control a display of the monitor device when the towing vehicle moves backward. The controller includes a display setting processing portion, a model display processing portion, a touch operation detection portion, and a movement direction model display processing portion.

A system and method for coupling a trailer. The system includes a base, a coupler, and an indicator. The indicator has a vertical portion and a horizontal portion. The vertical portion extends the horizontal portion to a plane where the horizontal portion is visible to a driver. The horizontal portion has a free end. When the free end is touching or adjacent to a trailer connector, then the trailer connector is aligned vertically over a trailer hitch. The trailer can be lowered, coupling the trailer to the vehicle.

An autonomous dock system for a vehicle, comprises a control system with instructions comprising steps for receiving a request to implement an autonomous dock routine. A vehicle speed and clutch position are calculated. A clutch position controller is commanded to maintain the calculated clutch position. An actual torque amount is iteratively detected as transferred across the clutch. A vehicle speed-control mechanism is commanded to maintain the calculated vehicle speed, and the actual vehicle speed is iteratively detected. When comparing the commanded vehicle speed to the detected actual vehicle speed indicates that the detected actual vehicle speed is below a speed threshold, and when the actual torque amount transferred across the clutch exceeds a torque threshold, the control system commands an increase in vehicle speed.
