Abstract

In the presented work, the vehicle propulsion controller (VPC) for parallel hybrid truck model has been modified to manage auxiliary power in advance based on the forthcoming traffic information. To simulate standard and real world conditions, constant highway driving cycles and real world driving cycles with different terrain types have been used to show the impact of looking-ahead control strategy on managing energy storage system and fuel economy improvement. The results revealed that the proposed looking-ahead control strategy for parallel hybrid truck has substantial contribution in preparing the system for forthcoming power demand. Fuel economy change for the model with looking-ahead control strategy has been improved from 0.5 to 3% for different terrain types comparing to the same parallel hybrid truck model without looking-ahead strategy. Furthermore, reducing equipment sizes while maintaining adequate power and improved fuel economy was one of the potential findings from the proposed model.
