Abstract: A system and method for utilizing multiple driver stations in a track vehicle is described. A primary driver station can utilize controls with hybrid drive by wire (DbW) functionality (i.e. hydro-mechanical and electric control). A secondary driver station and a tertiary driver station can utilize controls with DbW (i.e. electronic) control systems. The secondary and tertiary driver stations can be adapted for autonomous driving. The invention also includes a method of transfer between driver stations with safeguards for safety and reliability.

Abstract: There is disclosed an energy absorption device comprising a plurality of pillars mountable to a ceiling of a hull, each pillar having a fixed portion and a movable portion, the movable portion slidable relative to the fixed portion; a deformable material disposed between the fixed portion and movable portion such that the deformable material resist the sliding movement of the movable portion in one direction; the deformable material further adapted to permanently deform when a blast energy is directed towards the ceiling; and a seat assembly attached to the movable portion, the seat assembly adapted for an occupant.
