The project was about modeling and simulation of Series Parallel Hybrid Electrical Vehicle using the MATLAB/Simulink as the based software. Based on the vehicle's real specification and right components sizing, a SPHEV Simulink model was developed and simulated to observe and study the operations of SPHEV under various driving conditions. The model developed was a forward looking model utilizing the driver model controller to request for power demand. The controller would execute the power demand and choose which mode to be used. Since the SPHEV was a combination of series and parallel modes, a good control strategy was required to ensure the vehicle was operating at the right mode depends on the driving situation. The simulation of SPHEV model was based on Urban Dynamometer Driving Schedule (UDDS) reference drive cycle and it was successfully simulated. xPC Target as a powerful tool is used to rapidly implementing real time control system on a DC Motor. The xPC Target control system consist of three major components which are Host PC, Target PC and hardware. The motor is used as hardware of xPC Target as well as to represent the SPHEV system. The motor controller which has been designed in Host PC is compiled and downloaded to the Target PC which is running in real time operating system. The operating system will execute the controller and control the hardware. Variation of motor's load which also corresponds to variations of driving range in the SPHEV system will contribute to different speed of motor. The acquired speed is used by the controller to compensate with errors occur during the implementation.
