A transmission model for hardware-in-the-loop powertrain control system software development

Powertrain control systems engineers are increasingly being asked to deliver high quality products faster, under stricter emissions and fuel economy regulations as well as meet higher customer expectations. In order to meet these demands, control engineers are turning to computer-aided tools that support rapid development of quality products, such as hardware-in-the-loop (HIL) systems. In the paper, a transmission model that has been developed for the Visteon Powertrain HIL Project is described. The transmission model is used to verify the on-board diagnostics (OBD-II) and transmission control logic.
