Solutions for Testing Hybrid Powertrains

The rapid increase in development activities on hybrid powertrains is creating unique challenges for the management of powertrain development facilities and the test equipment suppliers to these facilities. In this article, the integration of the powertrain engineering design phase, the control and electric power management activities and the test facility, and vehicle based powertrain development phases including the use of hardwarein- the-loop (HIL) is reviewed. The specifi c powertrain features of both current and future hybrid powertrains are reviewed and the subsequent test equipment and test process requirements are translated down to specific equipment and operational solutions.
