In one embodiment, a steering system for an agricultural implement system includes a first actuating cylinder configured to rotate a first track relative to an implement frame where the first actuating cylinder is connected to a first frame of the first track, and a second actuating cylinder configured to rotate a second track relative to the implement frame where the second actuating cylinder is connected to a second frame of the second track. The steering system also includes a first fluid control conduit extending to a cap end of the first actuating cylinder, a second fluid control conduit extending between a rod end of the first actuating cylinder and a rod end of the second actuating cylinder, a third fluid control conduit extending to a cap end of the second actuating cylinder, and a steering control valve in fluid communication with the first and third fluid control conduits.

A trailer recognition device of a vehicle includes: a sensor sensing a distance value between the vehicle and a rear object; a controller detecting whether a trailer is connected, depending on an internal signal of the vehicle and the distance value and predicting a first hitch angle based on a vehicle model and a second hitch angle based on the sensor to generate a control signal; and a trailer mode controller controlling a trailer mode of the vehicle in response to the control signal.

A system for assisting a vehicle in reversing a trailer includes a vehicle steering system, a vehicle sensor outputting a vehicle velocity and a trailer sensor outputting a trailer yaw rate. The system further includes a controller controlling the vehicle steering system in reversing the trailer to cause a control parameter based on the trailer yaw rate and the vehicle velocity to converge toward a predetermined value.

The present disclosure relates to a method for steering a vehicle. A corresponding vehicle includes two steerable axles VA1 and HA1 each with an angle sensor, wherein a rear axle HA1 in an all-wheel mode is synchronously steered with the front axle VA1 in the opposite direction, this being designated as a 44 steering system. The vehicle further includes a control device for setting the steering angle of the axles based on the data provided by angle sensors.

A system for assisting in reversing of a vehicle-trailer combination includes a vehicle steering system and a controller. The controller outputs a steering signal to the steering system to maintain the vehicle-trailer combination along a straight backing path and determines a straight-backing offset of a hitch angle in the vehicle-trailer combination as a proportion of an integral of a measured characteristic of the vehicle-trailer combination that varies from a desired zero value.

A driver assistance device according to an embodiment includes a coupling angle acquirer that acquires a coupling angle between a towing vehicle and a towed vehicle coupled to the towing vehicle; and a notifier that issues a given notification in the towing vehicle when the towing vehicle is driven with the towing vehicle and the towed vehicle differing in orientation at a given value or more based on the coupling angle, the towing vehicle moves in a given distance or less while maintaining a steering angle, and the steering angle of the towing vehicle enables the towing vehicle and the towed vehicle to be placed in a serial state with the towing vehicle and the towed vehicle substantially matching with each other in orientation.

A transport trailer having a chassis and at least one floor platform mounting to the chassis and configured to transport a load. The at least one floor platform comprises at least one main plate and a metal sheet mounting to the main plate. The at least one main plate is fabricated from a porous metal material.

A vehicle, a single-wheelset/double-wheelset trackless train and a tracking and steering control method therefor are provided in the invention. The method includes the following steps. During traveling of the vehicle, steering information of the vehicle is continually collected by the controller. Information about a guiding front wheel turning angle, a controlled rear wheel turning angle, a vehicle body position angle, an included angle between vehicle bodies, and a vehicle travel time and speed is collected; an interval for data collection is determined according to a distance between a guiding front wheel and a controlled rear wheel; and when the controlled rear wheel travels to a certain point near a front wheel travel track, the controlled rear wheel is controlled to travel in a travel direction same as that when the front wheel travels to the point. According to the rear wheel tracking and steering control method, the objective that a controlled rear wheel operates in a manner of highly approaching a guiding front wheel track can be achieved; and the higher a data collection frequency is, the higher a track fitting degree of the front wheel and the rear wheel is.

An articulated vehicle assembly comprising a master vehicle having a master steering system and an onboard sensor arrangement configured to monitor at least said master steering system; a slave vehicle having a slave steering system and an onboard actuator arrangement configured to manipulate at least said slave steering system; an articulation system for articulating in a queue the master and the slave vehicles along a common longitudinal axis; and a processing unit configured to receive input signals from the onboard sensor arrangement and produce corresponding output signals to the onboard actuator arrangement to manipulate said slave steering system so as to maintain the master vehicle and the slave vehicle aligned along the common longitudinal axis, at least when the master vehicle performs a turn on a horizontal plane.

Provided are self-powered actively steerable converter dollies (SPASCDs) for long combination vehicles (LCVs), LCVs utilizing SPASCDs, and methods of operating such LCVs. These SPASCDs could be used with conventional tractors and/or specifically configured tractors. A SPASCD may include an electrical drive, which can generate power (e.g., to charge SPASCD's battery) or generate torque using the electrical power stored in SPASCD's battery (e.g., to assist the tractor during acceleration or going uphill). The SPASCD also comprises steerable wheels and a steering component, configured to change the steering angle of the steerable wheels. The steering angle may be changed in response to various inputs, such as the steering angle of the tractor's front steerable wheels, the steering angle of the steerable wheels of another trailer in the same LCV, sensor inputs, and the like. This steering feature allows change the track of the SPASCD, e.g., to follow the tractor's track.
