The trailer backup assist system may also include a steering input device, such as a rotatable knob, that is movable between a plurality of positions that each provide a desired curvature of the trailer. In addition, the trailer backup assist system may include a controller that determines an offset of the desired curvature when the knob is stationary in a central position. The control then generates a steering command for the vehicle to guide the trailer on the desired curvature, taking into consideration the offset.

A battery power system for a plug-in hybrid or electric tractor trailer employs a battery module which is carried by the trailer. A cable communicates with the battery module and connects with a connector on the cab for supplying power to power the electric motor of the cab. The cab can be disconnected from the trailer while the battery module on the trailer is charged. The cab can then be driven by the electric motor powered by the battery supply of the cab.

A remote and portable, hybrid power system comprising one or more of the following components: a solar system, batteries, a back-up generator, a wind energy system, and a communications system. The components are disposed on a platform that is portable and transportable to the remote location by a truck or other transportation vehicle.

A trailer backup assist system, according to one embodiment, includes a state estimator that determines a current position of a trailer relative to a plurality of waypoints. A trajectory planner may then incrementally generate a path from the current position to the plurality of waypoints. The trajectory planner has a first mode that generates first and second circular trajectories tangent to one another connecting between the current position and a waypoint of the plurality of waypoints. A second mode of the trajectory planner generates the second circular trajectory between the current position and the waypoint after the trailer traverses the first circular trajectory. Also, a third mode of the trajectory planner switches to the first operating mode when the trailer reaches the waypoint for guidance to a subsequent waypoint. A curvature controller guides the trailer based on a curvature of the respective first or second circular trajectories.

The invention provides for a high occupancy or heavy-duty vehicle with a battery propulsion power source, which may include lithium titanate batteries. The vehicle may be all-battery or may be a hybrid, and may have a composite body. The vehicle battery system may be housed within the floor of the vehicle and may have different groupings and arrangements.
