Virtual Development of Control Unit Functions for Fully Variable Valve Timing
Model-based testing of real electronic control units on hardware-in-the-loop simulators has become an established standard method for function development of combustion engines. Using a control for a continuously variable valve lift as an example, this article from dSpace describes a completely integrated development procedure covering everything from model-based controller design, including early validation on developers' own PCs, to electronic control unit tests on a hardware-in-the-loop simulator.
Integrated Development Procedure
Tougher requirements on fuel consumption and the introduction of stricter emission regulations are necessitating new systems and controls for combustion engines. For example, new control concepts for spark-ignition engines promise similar high potential fuel savings to those provided by diesel engines. The new concepts include new combustion processes such as HCCI, variable valve control timing, and variable valve lift, in which continuously variable valve...
