Target-based prototyping system applied to fuel control

We describe a target-based rapid prototyping system, MotoHawk, for controls development, vehicle or engine calibration, and fleet testing. MotoHawk features the capability of controlling various types of engines (gasoline and diesel engines from single-cylinder to multi-cylinder), auto-code generation of Simulink/Stateflow models to a family of production Electronic Control Units (ECUs), and a calibration interface incorporated in the models. Finally, an illustrative example of a MotoHawk application, the design and implementation of a fuel control strategy for gasoline engines, is discussed in detail.
