Abstract-Toyota Hybrid System (THS) is used in the current bestselling hybrid vehicle on the market-the Toyota Prius. This hybrid system contains a power-split planetary gear system which combines the benefits of series and parallel hybrid vehicles. In this paper, we developed a dynamic model of the THS powertrain and then apply it for model-based control development. Two control algorithms are introduced: one based on the stochastic dynamic programming method, and the other based on the equivalent consumption minimization strategy. Both approaches determine the engine power based on the overall vehicle efficiency and apply the electrical machines to optimize the engine operation. The performance of these two algorithms is assessed by comparing against the dynamic programming results, which are non-causal but provide theoretical benchmarks for other implementable control algorithms.

The mechanical hybrid vehicle: an investigation of a flywheel-based vehicular regenerative energy capture system. Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 222(11), pp. 2087-2101. doi: 10.1243 This is the accepted version of the paper.This version of the publication may differ from the final published version. Abstract: Capturing braking energy by regeneration into an on board energy storage unit, offers the potential to reduce significantly the fuel consumption of vehicles. A common technique is to generate electricity in the motors of a hybrid electric vehicle when braking, and use this to charge an on board electrochemical battery. However, such batteries are costly, bulky and generally not amenable to fast charging as this affects battery life and capacity. In order to overcome these problems, a mechanical energy storage system capable of accepting and delivering surges of power is proposed and investigated. A scale physical model of the system, based around a flywheel, a planetary gear set and a brake, was built and operated in a laboratory. Tests showed that the proposed system could be used to store and provide braking energy between a flywheel and a vehicle, the latter emulated by an air-drag dynamometer. This validated the operating principle of the system and its computational model. Further, a computational analysis of a full size vehicle incorporating the mechanical energy storage system was conducted. The results showed that the utilisation of this system in a vehicle, when compared to a conventional vehicle, led to reductions in emissions and fuel consumption.
