Design and Implementation of an Integrated Development Environment Consisting of Engine Rapid Control Prototyping and Real Time Vehicle Simulation

To meet the ever increasing requirements for engines and vehicles in the areas of performance, fuel economy and emission, and reduce product development time, we see the need for an integrated development environment which combines engine rapid control prototyping (RCP) capability with real-time vehicle simulation capability using an engine dynamometer in the test cell. Design and implementation of such a system with the ADX universal high-speed system controllers are described. An application example of simulating an FTP-75 cycle in the test cell while the engine is under ADX control is presented. This system moves a lot of work from the whole vehicle environment to the engine test cell environment, and is a powerful tool for quick development and testing of control algorithms as well as calibration.
