"Hardware In the Loop" (HIL) Real Time SimulationBest possible fuel consumption, emissions and driveability of a complete power train can only be achieved by maximum electronic system integration of the engine, transmission and other vehicle subsystems in the electronic powertrain and/or drive train management.
As electronic systems are commonly used to control engine, transmission and many other vehicle functions, the control of the components and the interaction between the components become more complex. Simple trial and error methods in the application of electronic control systems may lead to component damage and considerable time loss when performed on engine and transmission test beds.
Testing networks of electronic controllers in a safe environment is a must. Just combining individually developed electronic control subsystems may cause a lot of problems.
The following subtasks and field applications can be performed:
 | ECU / TCU testing: checking functionality | | Testing of (new) data sets and control parameters | | Creating the controller architecture, testing the controller networks (CAN) | | Function development: new control functions for vehicle or components (engine, transmission, aftertreatment), diagnosis | | Establishing and testing the communication between the controller systems (e.g. for CAN or similar bus based systems) | | Creating, programming and testing of operating strategies including development of limp-home strategies | | Pre-calibration of vehicle management systems and other vehicle subsystems | | Automated pre-calibration: HIL system allows programming of automatic procedures that can fill up e.g. engine control maps, OBD tests etc. |
