The University of Delaware (UD) has been conducting a very successful Fuel Cell Hybrid Bus Program since 2005 to research, build and demonstrate fuel cell powered buses and hydrogen refueling stations in Delaware. The buses have been shown to be reliable, safe, and efficient while producing zero emissions. Several tangible benefits from the UD Fuel Cell Bus Program can be leveraged for the proposed work. First, the project has developed a powerful Matlab/Simulink based simulation tool called LFM to simulate the performance of the buses on a variety of driving schedules looking at key outputs such as hydrogen consumption, battery state-of-charge, and fuel economy. Second, the project has already developed a one-way cellular link between the buses and a server in the lab for real-time analysis and fault-detection, which the project proposes to convert to a two-way communication to optimize both the transportation system and the vehicle's control system in real-time. The project will use this fleet of fuel cell hybrid buses and the LFM simulation tool to analyze and solve many problems related to urban traffic congestion. The project will also conduct simulations with other hybrid vehicle types and recruit voluntary drivers with such vehicles for validation studies. A traffic model will be set up to simulate and find the optimal route for individual vehicles based on historical and real time traffic data which can reduce congestion and save fuel. Then, a two way communication system between sever and bus will be developed to exchange vehicle data and navigation suggestions. Finally, optimization model will be developed to generate the optimal power control strategy for the hybrid bus to improve fuel economy and fuel cell durability under a variety of traffic and weather conditions. |
