The objective of this proposed Phase I study is to examine and evaluate primarily though simulation tools such as CADSI and more specific higher level DTI developed programs, the advantages of integrating leading edge subsystems into a modular trailer concept compatible with future AAN requirements. The concept proposed is a logistically flexible, high mobility trailer platform utilizing active suspension/in-wheel drive swing arm modules with hybrid electric power and a control system that will provide an autonomous platform where an intelligent system determines desired steering, braking and power commands. The study will investigate the hierarchical control methodology, performance and logistical utility gain of using a umbilical power control cable system that will couple vehicles and trailers together in a combination of variants and provide dynamic control and appropriate movement of coupled vehicles as they relate to each other. Performance optimization of the Integrated suspension/drive swing arm module and fuzzy logic controls will be explored and independent in-wheel propulsion drive configurations will also be selected for simulation and study. This concept has the potential to achieve greater trailer performance levels in mobility, and logistics. The information and preliminary design produced will provide a solid foundation for a successful phase II program.
Benefits: It is expected that the new technologies examined in this program when applied to the proposed modular trailer concept could yield substantial performance breakthroughs for utilization of independent electric drive for traction control and skid steer capability, and an advanced suspension to increase load capacity and high mobility. These technologies developed and validated during the HMT program should be equally applicable to commercial, recreational and military interest. Once matured the commercial and recreational markets should drive future technology advancements for the military to further reducing operating and support cost of mobility for the military.
