The present application relates to a method and apparatus for generating a graphical user interface indicative of a vehicle underbody view including a LIDAR operative to generate a depth map of an off-road surface, a camera for capturing an image of the off-road surface, a chassis sensor operative to detect an orientation of a host vehicle, a processor operative to generate an augmented image in response to the depth map, the image and the orientation, wherein the augmented image depicts an underbody view of the host vehicle and a graphic representative of a host vehicle suspension system, and a display operative to display the augmented image to a host vehicle operator. A static and dynamic model of the vehicle underbody is compared vs the 3-D terrain model to identify contact points between the underbody and terrain are highlighted.

Method and apparatus for invisible vehicle underbody view

An economical to manufacture and simple to install and remove gas charged fluid pressure accumulator including a cup-shaped accumulator body with an integral dome at one end and an integral in-turned annular lip at the other end, a piston slidably disposed in the accumulator body, and an external screw thread on the accumulator body. The accumulator body is screwed into a threaded counterbore until the annular lip bears against a bottom wall of the counterbore with a fluid port of the manifold inside of the projection of the lip on the bottom wall. A seal ring in a groove in the bottom wall of the counterbore bears against the annular lip to seal the chamber of the accumulator defined between the bottom wall and the piston.
