Abstract: In this paper, we present a review of the recent advances in hybrid vehicle powertrain architectural design. The paper begins with a discussion and categorisation of the various types of hybrid vehicles. The current leading technology is the one-mode design of the Toyota Hybrid System, and the intent of the state-of-the-art architectures is to improve upon the perceived weaknesses of the one-mode design. The proposed designs employ multi-regime architectures that allow for the transmission to operate in any one of series, parallel, or power-split configurations, depending upon the road load, driver demand, and control strategy. These new designs found in the literature are discussed and compared. The work allows further study and detailed modelling of the promising multi-regime architectures to be carried out.

Keywords: hybrid vehicles; power-split; vehicle modelling; vehicle simulation; powertrain design; vehicle design; transmission configurations; road load; driver demand; control strategy; multi-regime architectures.
