An agricultural planter is configured to be moved over a supporting surface by a vehicle. The agricultural planter includes a frame and a planter assembly coupled to the frame. A first propulsion assembly is coupled to the frame at a first position with the first propulsion assembly having a first traction member configured to engage the supporting surface. A second propulsion assembly is coupled to the frame at a second position with the second propulsion assembly having a second traction member configured to engage the supporting surface. A drive assembly is operably coupled to at least one of the first or second propulsion assemblies and configured to drive at least one of the first or second traction members during operation of the planter assembly. The first traction member is configured to be driven independently of the second traction member.

A method is provided for controlling a hydraulic hybrid vehicle, the hydraulic hybrid vehicle including: a first pair of wheels and a second pair of wheels; an internal combustion engine connected to the first pair of wheels for propelling the hydraulic hybrid vehicle; and a hydraulic propulsion system including a first hydraulic machine connected to the second pair of wheels, the method including the steps of; receiving a signal indicative of a driving condition, including vehicle speed, of the hydraulic hybrid vehicle; comparing the vehicle speed of the driving condition of the hydraulic hybrid vehicle with an upper predetermined threshold speed limit; determining if the vehicle speed of the driving condition is higher than the upper predetermined threshold speed limit; and when the vehicle speed is higher than the upper predetermined threshold speed determining, based on the driving condition, control parameters for operating the first hydraulic machine; and controlling the control parameters of the first hydraulic machine for operating the first hydraulic machine. The invention also relates to a control unit and a hydraulic hybrid vehicle.

A hitch angle module determines a hitch angle based on an input from at least one of a vehicle rear camera and a hitch angle sensor. The hitch angle is an angle between a longitudinal centerline of a trailer and a longitudinal centerline of a vehicle. A trailer load sensor measures a load on a trailer hitch of the vehicle. A trailer wheel speed sensor measures a wheel speed of the trailer. A trailer dimension module determines at least one of a width of the trailer, a mass of the trailer, a drawbar length of the trailer, a height of the trailer, and a trailer hitching length of the vehicle based on at least one of the hitch angle, the trailer load, and the trailer wheel speed. The trailer hitching length is a distance from a rear axle of the vehicle to a distal end of the trailer hitch.

An electric moving device for vehicles, relating to the trailer area, having a base frame, a travelling mechanism, a steering handle mechanism, a driving mechanism and an electric control assembly. The base frame has a support frame and a connecting frame, and the connecting frame is disposed over the support frame. The travelling mechanism has roller wheels on the support frame, and the driving mechanism has a driver and a clutch system. The driver and clutch system are located on two sides of the support frame separately. The clutch system has an input end connected to the driver in a transmission way and an output end connected to the roller wheels in a transmission way. The steering handle mechanism is rotationally fixed to the base frame so the steering handle mechanism could deflect to the two sides of the travelling direction of the moving device for vehicles.
