The aim of this paper is to provide a dynamic model of the Toyota Hybrid System (THS) for simulation and control purposes in the case of fault of one of the electric machines. The two three-phase electric machines that are commonly used in THS are here replaced by two five-phase machines. The model of the whole system is realized by using the Power-Oriented Graphs modeling technique and includes the dynamics of the engine, electric machines, planetary gear, transmission and vehicle. A rule-based control strategy is used to operate the vehicle in different operation modes and a fault-tolerant control is applied in the case of electrical machine failure. Simulation results are given in both healthy and fault condition to show the effectiveness of the dynamic model and the robustness of the proposed control.

Abstract
The aim of this paper is to provide a dynamic model of the Toyota Hybrid System (THS) for simulation and control purposes in the case of fault of one of the electric machines. The two three-phase electric machines that are commonly used in THS are here replaced by two five-phase machines. The model of the whole system is realized by using the Power-Oriented Graphs modeling technique and includes the dynamics of the engine, electric machines, planetary gear, transmission and vehicle. A rule-based control strategy is used to operate the vehicle in different operation modes and a fault-tolerant control is applied in the case of electrical machine failure. Simulation results are given in both healthy and fault condition to show the effectiveness of the dynamic model and the robustness of the proposed control.
