Abstract

The development of hybrid vehicles is one of the current approaches to improve fuel efficiency. California Polytechnic State University San Luis Obispo's current platform is a diesel-hydraulic series hybrid. This thesis provides a MATLAB based model and simulation for this platform to be used as a development tool. The model is highly configurable and the code employs parallel processing to allow for rapid simulation of a range of inputs. A best-efficiency control strategy is implemented to select between operational modes containing optimized engine and hydraulic system parameters during the simulation. Results from the simulations are comparable to results from similar simulations.
