Provided is a vehicle drive assisting apparatus capable of allowing a driver to recognize a road surface condition which can be used for reference in steering following wheels or a road surface condition which can be used for reference in turning. Such vehicle-drive assisting apparatus includes a wheel position storing section storing a position of a wheel when a vehicle effects traveling, a road surface information acquiring section acquiring road surface information indicating a road surface condition of a road surface on which the vehicle has traveled, and a display image generating section generating a display image of the road surface information stored and relating to the wheel position on a displaying unit provided in the vehicle.

A system and apparatus that reduces tire scrub on a truck and or trailer during turns. The system minimizes the redistribution of the load among the tires thereby spreading the load of the trailer or truck among the tires avoiding unnecessary overloading. The system operates without operator intervention and is capable of operating automatically on trailers, without control signals from the truck.

Disclosed are a control device and a control method for a damping force variable damper. The control device includes: a damping force setting part setting a damping force target value generated in each damping force variable damper based on lateral acceleration, yaw rate and vehicle speed of the vehicle; a driving current setting part setting a driving current generated in each damping force variable damper based on the damping force target value; and a cornering state judgment part determining the cornering status of the vehicle based on at least one of the lateral acceleration, steering angle, yaw rate and roll angle. When it is determined that the vehicle is in the initial cornering state, the rear wheel damping force target value of the vehicle is set to be higher than the front wheel damping force target value of the vehicle.

Methods for configuring a suspension system for a vehicle are disclosed such that the suspension system has zero scrub radius and zero bump steer. The method details the specific steps required to achieve these goals.

A multi-axle transport trailer having a plurality of axles includes a suspension comprising air bags associated with each axle, the air bags in communication with an air source, wherein air bags associated with different axles are capable of having different air pressures therein. The trailer further optionally includes a steering system associated with at least one axle, the axle including a tie rod connected between wheels on both ends of the axle, the steering system comprising cylinders configured to articulate the wheels, and a sensing device configured to monitor movement of the tie rod and facilitate actuating the cylinders to turn the wheels.

A work vehicle with the cylinder cushioning arrangement includes two frame members coupled together with two hydraulic cylinders that are cross-coupled to each other. Each of the two hydraulic cylinders includes a flow-restricted port (at either its rod end or the cylinder end) that throttles hydraulic fluid flow.
