Performance Evaluation of an Eco-driving Controller for Fuel-Cell Electric Trucks in Real-World Driving Conditions
Range anxiety in current electric vehicles is a challenging problem, especially for commercial vehicles with heavy payloads. Development of electrified propulsion system with multiple power sources such as fuel cell is an active area of research. Optimal speed planning and energy management, referred to as eco-driving, can substantially reduce the energy consumption of commercial vehicles, regardless of the powertrain architecture. Eco-driving controllers can leverage look-ahead route information such as road grade, speed limits, and signalized intersections to perform velocity profile smoothening, resulting in reduced energy consumption . In hybrid powertrain architectures, such as fuel cell electric vehicles, eco-driving also has an impact on the energy management, as it alleviates the variability of fuel cell power demand increasing the overall electric range of the vehicle.
