Hybrid electric vehicle with hydrogen fueled internal combustion engine could be an interim between current vehicles and fuel cell vehicles which are thought to be more of far term reality. This paper introduces the hydrogen engine powered parallel hybrid electric vehicle developed by Texas Tech University Advanced Vehicle Engineering Lab. It presents the innovative use of LabVIEW Real-Time controllers to develop the prototype vehicle powertrain control system. Then it discusses the hydrogen engine control issues and presents the development of the engine control unit by LabVIEW FPGA. Vehicle communication issues among the distribution management system are presented. The vehicle test results are also shown in this paper.

Texas Tech University's FutureTruck team has converted a stock 2002 Ford Explorer™ to a fuel cell powered hybrid-electric vehicle to enter into the 2002 FutureTruck Challenge. The internal combustion engine was replaced with a Honeywell manufactured hydrogen fuel cell. The fuel cell requires hydrogen, oxygen, and de-ionized (DI) water systems to produce power. Two AC induction motors drive the vehicle and there are two 270VDC nickel metal hydride (NiMH) battery packs to store energy. Water, heat, air and small amounts of hydrogen are the only emissions of the vehicle, which is the main benefit of the conversion. The team also sought to maintain, as much as possible, the comforts and performance options a driver would enjoy on a stock vehicle.
