During the production controller and software development process, one particularly critical step is controller and software verification. There are various ways to perform this verification.  One common method is to use an RT-LAB based TestDrive (hardware-in-the-loop) bench to emulate powertrain hardware for development and validation of powertrain controllers and software.

A key component of an HIL bench is the plant dynamics model used to emulate the external environment of a modern controller, such as engine (ECM), transmission (TCM) or powertrain controller (PCM). This is the algorithms and their software implementation can be exercised to confirm the desired results.

By developing a transmission plant dynamics model, test cases can be created to validate targeted areas of the control software for confirmation of the expected results from software release to release. This is especially important when algorithm/software development timing is aggressive and the management of development activities in a global work environment requires high quality, and timely test results.

This presentation presents development of a 6-speed automatic transmission plant dynamics model for execution on the hardware-in-the-loop (HIL) test bench, for validation of production transmission controls software. The modelling method, model validation, and application in an HIL test environment are described in detail.
