This paper describes a novel model based real time simulation approach to test, validate and calibrate electronic controllers for Hybrid Electric Vehicle (HEV) applications. The performance of the Hybrid Control Unit (HCU) needs to be evaluated on multiple vehicle attributes such as fuel economy, acceleration and drivability objectives. The multi attribute evaluation requires a higher level of detail for the vehicle simulation model where the energy flow and drivetrain dynamics are represented accurately. Given the high mechatronic content and the strong interactions among the various controllers in HEVs, it becomes necessary to simulate many of the vehicle controllers on the real time platform. The higher fidelity vehicle model coupled with the realistic behavior model of the controller network poses challenges in setting up the real-time Hardware In the Loop (HIL) test platform where the vehicle level attributes can be studied. The real time simulation setup process, its challenges and the methods used to overcome these challenges are described in this paper.
