The dynamic, predictive information system and method assigns shipping assets (drivers-tractors-trailers) from carriers to transport orders by shippers. Computer databases hold shipping asset data. Specific transport orders are electronically joined to specific driver-tractor-trailer combinations. A search and sort routine produces resulting records based upon proximity, trailer type, proximity of the joined driver-trailer combination, carrier service region and pick-up and delivery date constraints. The sort is by price or performance indicators which are pre-selected shipper ranges matched to historical shipping data from carriers. The system books the carrier, the driver-tractor-trailer combination and the shipper to transport order with an electronic communications phase. In a truck lane scenario, the system joins a specific driver and a specific tractor and a non-specific trailer to a specific transport order. GPS data and electronic shipping document data from PDAs with the drivers is logged into the system and is viewable by the participants.

The invention relates to a method for determining a set steering angle β0 of steered wheels of a vehicle comprising a tractor and a trailer that is articulated with regard to the tractor. This method makes it possible to produce a set value that can be used for various purposes. This set value can thus be used for controlling an actuator acting upon the steering angle or for being communicated in order to inform the driver. According to the invention, during reversing maneuvers: based on a target point C via which the driver would like the path of the vehicle to pass, an angle set value ?c between the axes of the trailer and of the tractor is determined according to said target point C and to the dimensions of the vehicle, and; the set steering angle β of the steered wheels is determined according to a servo-system causing the measured angle ? between the axis of the trailer and the tractor to tend toward said angle set value ?c.

An air drag reduction apparatus includes left and right panels and top and bottom panels for mounting to the rear doors of a tractor trailer along the top, bottom and side edges thereof. Hinges are interposed between the panels and the doors so that the panels can pivot about the hinges between an extended drag-reducing position and a collapsed position generally adjacent the rear doors. Stop devices releasably secure the panels in the extended position, and biasing devices such as tensioning springs are operative to bias the panels outwardly and rearwardly to the extended position and are further operative to permit the panels to pivot between the extended position towards and to the collapsed position upon impact and contact from an external object occurring and then return to the extended position substantially immediately upon contact ceasing thereby significantly reducing the impact damage. The apparatus also includes a ramp and wheel arrangement to facilitate opening and collapsing of the panels. The apparatus of the invention also includes an outwardly extending panel protection member projecting from the lower corner of the panel in a position for being contacted by external objects during movement of the vehicle to thereby prevent direct contact between an external object and the panel and cause the panel to move toward its collapsed position

An aerodynamic base drag reduction apparatus and method for bluff bodies, such as tractor-trailer trucks, utilizing a pair of lift surfaces extending to lift surface tips and located alongside the bluff body such as on opposing left and right side surfaces. In a flowstream substantially parallel to the longitudinal centerline of the bluff body, the pair of lift surfaces generate a pair of counter-rotating trailing vortices which confluence together in the wake of the bluff body in a direction orthogonal to the flowstream. The confluence draws or otherwise turns the flowstream, such as the flowstream passing over a top surface of the bluff body, in and around behind a trailing end of the bluff body to raise the pressure on a base surface at the trailing end and thereby reduce the aerodynamic base drag.

An apparatus that provides an electronic image of areas around sides and rear of a large tractor trailer rig produced on a weatherproof screen that is located on the lower portion of the driver's side mirror. One (1) camera would be located on the rear of the trailer in a center mounted position, while another camera would be located on a passenger side near the front of the vehicle so that it can see the entire side of the vehicle. The cameras would be equipped with fixed wide-angle lenses. The video signal from each camera would be routed to an automatic switcher that displays each signal for a pre-determined time or allows for the manual selection of either camera on a permanent basis. The video signal is then displayed on the weatherproof monitor portion of the side view mirror. In such a manner the truck driver can look at the mirror and the monitor in order to see all three (3) sides of the vehicle at once. This feature eliminates looking in various directions to check for obstructions while backing up or changing lanes.
