US ARMY COMMON POWERTRAIN CONTROLLER DEVELOPMENT FOR AVDS EFI ENGINE APPLICATION IN M88 VEHICLE

by John Yancone; Jamey Cates; Dan Pace; Paul Kruchko

Abstract

This paper outlines the results from an ongoing collaborative development effort to apply a new powertrain controller in a real combat vehicle application. Specifically, TARDEC and L3T CPS have partnered to demonstrate a production viable electronically controlled fuel injected (EFI) version of the AVDS 1790 diesel engine, used in the M88 HERCULES vehicle. Highlights of the development project focus on coordinated engineering activity involving the following key enablers. • The neXtECU jointly developed by ETAS and TARDEC, custom engineered to become a common powertrain controller for use on the Army’s future family of combat vehicles • Engine control software jointly developed by TARDEC and L3T to perform EFI fuel system controls and auxiliary powertrain functions using the neXtECU • AVDS 8CR 1050 hp engine with L3T design modifications to incorporate a derivative of a commercially available EFI fuel system.
