Hybrid electric vehicle’s (HEV’s) use electric motors and combustion engines to provide their required power. Power transmission in hybrid electric vehicle is accomplished through various configurations, including series, parallel and series-parallel. In these vehicle’s, the control strategy determines the share of the electric motor and combustion engine in the supply of power required by the car. Therefore the role of the electronic control unit in hybrid electric vehicle is very important. One of the main challenges in designing such unit is investigating the accuracy of its performance and the control strategy implementation on an electronic hardware via repeatable and comprehensive tests. In this thesis, a hardware-in-the-loop simulation is presented for testing of the electronic control unit for hybrid electric vehicles. In order to locate the controller in the hardware in the loop simulating using the forward model is required. Therefore initially the forward simulation of the parallel hybrid electric vehicle has been done and then to verify the model, the results are compared with the advisor software. The results showed that the simulation of the parallel hybrid electric vehicle is done correctly.
Also in order to model the driver in forward automobile simulation, two models of PI and backward model, is presented. Comparing the results of both models shows that the PI model produces more accurate results than the backward model.
In the next step, an electric assist control strategy and the implementing this strategy on the electronic hardware is described. At the end, in order to verify the implementation, the controller is placed in the hardware in the loop test. The results of the hardware in the loop test indicate that the control strategy is implemented correctly on the hardware.
