Abstract:
Reducing energy consumption in transportation is not only a globally responsible
goal for impacting climate change but also a growing consumer demand. For the
emerging mobility as a service market, energy consumption is important for both
the fleet owner and the customer of a carsharing service. However, designing an
appropriate powertrain architecture that meets the technical specifications
needed to appeal to both stakeholders is challenging. The emergence of viable
Connected and Automated Vehicle (CAV) technology in recent years holds great
promise in enhancing vehicle capabilities in terms of energy consumption and
drive quality that would appeal to this market, particularly in a hybrid
vehicle. This article presents two P4 parallel hybrid charge sustaining
powertrain architectures proposed for the EcoCAR Mobility Challenge (EcoCAR)
competition and the effects of implementing CAV technology in these
architectures. Focus is placed on the models used to simulate the vehicle
dynamics, and how the modeling affects the energy consumption in simulation for
a given drive cycle with the chosen Energy Consumption Minimization Strategy
(ECMS). The simulated models are validated by the use of real-vehicle data from
the Environmental Protection Agency (EPA) [1]. Energy consumption results show a promising fuel economy of 28.9
and 29.7 miles per gallon (mpg) for the two proposed architectures for the
hybridized vehicle. The performance of the Society of Automotive Engineers
(SAE)-defined drive quality metrics is evaluated for future robust hybrid
vehicle and CAVs control strategy development. The CAV control strategy is
presented with a discussion of its impact on drive quality and energy
consumption with the use of vehicle-to-infrastructure technology for the chosen
hybrid control strategy. This article details the implementation of CAV
technology alongside a hybrid control strategy to decrease the fuel consumption
of a Chevrolet Blazer with integrated hybrid components.
