HIL and RCP tools for embedded controller development in hybrid vehicles

Electronic control units (ECUs) that control the energy flow through a hybrid powertrain have played a major role in the success of this technology. Hardware-in-the-Loop (HIL) simulation is a testing process that has proven to be an industry standard for ECU testing and validation. This paper briefly reviews the state-of-the-art technology in HIL testing of hybrid electric vehicles (HEVs). The lessons learned from real-world challenges faced during ECU testing and proven solutions to such problems are also discussed. In addition rapid control prototyping (RCP) related to motor control and controls development, on a hybrid ECU, is discussed.
