The BMW Hydrogen 7, currently in development, is a hybrid vehicle designed to combine the pleasure of driving a BMW with the benefits of practically emission-free mobility. This paper discusses the challenge of developing engine simulators for the Hydrogen 7, as well as the solution: a complete HIL testing environment for engines designed by National Instruments.


For software development tasks, set up and safeguarding of the engine control units for the BMW model platform was adapted to the hydrogen requirements and the HIL delivery was improved through the use of industrialized processes. The availability of HIL system solutions first used with the Hydrogen 7 project was also used to improve the HIL supply for other BMW power train projects.
