An apparatus includes a base frame, first and second bins, first and second hydraulic assemblies, and a computer controller. The first hydraulic assembly is configured to selectively raise and lower the first bin relative to the base frame. The second hydraulic assembly is configured to selectively raise and lower the second bin relative to the base frame. The first and second hydraulic assemblies are individually actuable, and their actuation is coordinated by the controller. In another aspect, a method for transferring product using an apparatus includes inputting to a computer controller a first threshold rate of change in weight signals of a weight sensor; relaying a plurality of weight signals from the weight sensor to the controller; calculating a determination by the controller at least in part on whether the threshold rate of change has been exceeded; and automating actuation of a hydraulic assembly based on the determination.

Disclosed are a power assisted towing mode control method and system for ecofriendly vehicles. The power assisted towing mode control method is executed to control a power assisted towing mode between a first vehicle as a towing vehicle and a second vehicle as a towed vehicle, and includes determining, by the first vehicle, whether or not an accelerator pedal amount exceeds a threshold value, calculating, by the first vehicle, driver request torque based on the accelerator pedal amount, calculating, by the first vehicle, motor allowable torque based on the driver request torque, receiving, by the second vehicle, the motor allowable torque and calculating motor dischargeable torque based on the motor allowable torque, and performing, by the second vehicle, motor torque output based on the motor dischargeable torque.

A tow configuration may include a tow vehicle and first and second trailers. The intermediate trailer hitch angle with the tow vehicle is controlled with one objective being to improve the off-tracking performance of the other trailer. The hitch angle may be controlled through steerable wheels at the intermediate trailer or through wheel differential steering at the intermediate trailer.

Systems and methods for a virtually coupled modular transportation system. A first module and a second module, in each for transporting a payload, comprise non-physically coupled vehicle sections. In an embodiment, a controller determines a target orientation between modules. In another embodiment, at least one position detection device determines an actual orientation between modules. A motor in at least one module may receive signals from the controller to position the modules in the target orientation. A plurality of wheels on each module may receive an independent amount of torque to position the modules. In another embodiment, at least one module comprises a rechargeable electric motor.

Systems and methods are provided for coordinating and controlling power flow during in-flight bidirectional energy transfer events between an electrified vehicle, one or more charging trailers, and optionally, one or more electrified recreational vehicles. The systems and methods may prioritize energy transfers between each connected energy unit based on various parameters, including but not limited to in-transit travel logistics, environmental information, time of day, etc. Charge energy may be transferred to the appropriate power source to meet customer needs with varying levels of priority according to an energy transfer prioritization control strategy that is derived from the various inputs that are considered.

A linkage system includes at least one adapter and a connector. Each adapter includes a clamp configured to attach to a frame of a wheelchair. Each adapter includes a pivot angle limiter configured to attach to the clamp. The pivot angle limiter includes a top plate and a bottom plate, each having a central hole through which a pivot shaft is insertable to define a pivot axis for a connector to rotate about. The pivot angle limiter includes first and second barriers, each extending between the top plate and the bottom plate. The first and second barriers define a maximum pivot angle that has a vertex at the pivot axis. The at least one adapter may include a first adapter connected to one end of the connector and to a first wheelchair, and a second adapter connected to an opposite end of the connector and to a second wheelchair.

A trailer, in particular a utility trailer, for road vehicles on which an extendable current collector or an electrical contact element for an inverted current collector is placed.

The invention relates to a lane guidance system (10) for guiding and stabilising a vehicle axle along a lane, comprising a Watt linkage arrangement for connecting, in relatively movable manner, the vehicle axle to an underside (x) of a chassis, wherein the Watt linkage arrangement has at least two Watt linkages (20) which correspond in their guide direction (F) and are arranged in the transverse direction (Q), wherein the Watt linkage arrangement has a guide element (30) for guiding the vehicle axle along a straight line in the guide direction (F). According to the invention, the Watt linkages (20) are fastened, by means of their longitudinal ends (22, 24), to the guide element (30) and to the chassis, wherein the guided vehicle axle is a trailer axle (A) of a semitrailer.
