Improving Fuel Economy and Acceleration by Electric Turbocharger Control for Heavy Duty Long Haulage
Todays vehicle industry is converging more to the use of three phase electrical
architectures, due to hybridization. This paper investigates the potential of using an electric
turbocharger in a long haulage application during highway driving. A charge sustainable control
strategy is developed and implemented, tuned and evaluated on a heavy duty truck model. The
benefits of using an electrical turbocharger on a heavy duty diesel truck, from a long haulage
perspective, are evaluated. By calibrating the implemented controller, long haulage driving
routes can be charge sustainable and consume less fuel than a conventional truck with fix
turbine geometry.
