Dual-motor electric powertrain offers the independent control and less energy consumption in plug in hybrid electric vehicle model. The component sizing and control strategy are play the important role in dynamic control, power management and energy saving. The proposed system vehicle architecture comprises the dual motor, downsized engine and synchronizer. For optimizing the dynamic load sharing with the dual-motor powertrain configuration, rule-based fuzzy logic control strategy is implemented. The variable load will be managed by the way of selecting different transmission topologies using fuzzy logic control strategy. This dual-motor architecture configuration is simulated using Simulink software. Single motor propulsion drive control is engaged for all driving pattern except the peak load condition. In peak load, such as acceleration mode and high-speed mode, the dual-motor power transmission is engaged. The powertrain configuration is test at different dynamic and load conditions. As a result, it shows the better drivability, high efficiency and extended driving range.
