This report provides an overview of recent technical solution adoption rates by fleets from detailed fleet surveys. Manufacturers’ contributions in terms of technology development, cost reduction, durability and refinement will also be discussed. OEM vehicle integration and product line offerings (standard, optional, and post-production upfits) are shared. All of this background will set the stage for a review of the proposed Greenhouse Gas Phase 2 regulations, the technologies expected to be utilized to meet the targets, and the hurdles the industry must successfully clear for profitable fleet use in commercial vehicle freight transportation. Fuel efficiency has always been important to fleets and as fuel costs have risen, a plethora of fuel efficient technologies have emerged. The industry also cares about sustainability and emissions reductions and now Greenhouse Gas regulations exist to further encourage development, integration and adoption of such technologies.

Meeting the challenges of today's competitive and customer oriented transportation environment requires quick actions. Navistar's Advanta Concept Truck was developed in a very short time period, barely two months from concept to show truck. A newly engineered model with a new technology engine and new interior contributed to the exciting product content. New technologies such as Solids Modeling and Rapid Prototyping made some of the features possible. Following several months of shows around the country, another challenge began. “Clones” and kit parts were made from the concept truck.

This paper describes a method of integrating an accelerator position sensor and an idle validation switch to optimize the coordination of these two functions in a vehicle throttle control system.
