Co-simulation of Buses Equipped with Hybrid and Electric Drive Systems
7.1
Development of Co-simulation Models CRUISE—TruckMaker
The CRUISE—TruckMaker interface is based on the co-simulation process of the models for drive systems developed in the AVL CRUISE application, which equip the vehicle models developed in the IPG TruckMaker application [1]. If a AVL CRUISE powertrain is chosen in the vehicle data set TruckMaker starts the AVL CRUISE simulation program during the initialization phase of the Test Run simulation. A TruckMaker working directory is created over main menu File—Project Folder—Create Project (Fig. 7.1). Selecting TruckMaker working directory over main menu: File—Project Folder—Select. Preparing a AVL CRUISE powertrain for TruckMaker co-simulation requires the introduction of several new components in AVL CRUISE (TM-Car and Hub component) as well as usage of system GUI feature and SAM calculation task. On AVL CRUISE side the preparation for co-simulation are [1]: • Building model with specific components—modules for co-simulation (TM-Car and Hub module); • Using system/sub-system to switch between AVL CRUISE stand-alone simulation and co-simulation with TruckMaker; • Setup SAM calculation task of co-simulation; • Some special modules needed for AVL CRUISE stand-alone simulation must be excluded in co-simulation model (Vehicle, Cockpit, Monitor, etc.). On TruckMaker side the preparation for co-simulation are: • Creating CRUISE working directory inside a directory TruckMaker; • Copying and renaming the calculation kernel file (CRUISE\bin\CRUISE_m.dll in TruckMaker\lib\CRUISENT.dll); • Selecting AVL CRUISE powertrain and Project Folder for co-simulation. © Springer International Publishing Switzerland 2016 B.O.

Fig. 7.1 Defining a new project as new project
On both AVL CRUISE and TruckMaker the preparations for co-simulation are: • Harmonizing SimParameters and Memory Management. The model with interface for co-simulation defined in AVL CRUISE corresponding to the powertrain will be loaded in IPG TruckMaker in order to equip the vehicle model simulated in this application. From the Powertrain menu of the vehicle configuration system (Vehicle Data Set) in IPG TruckMaker, the AVL CRUISE option is chosen, following that through selection, the project model for co-simulation built in AVL CRUISE will open on the Project line of command. The new models built for co-simulation are presented in Fig. 7.2 (bus equipped with thermal engine), Fig. 7.3 (hybrid bus), respectively in Fig. 7.4 (electric bus), the data entered will then be connected and defined [2]. The TM-Car component defines the interface in co-simulation between AVL CRUISE powertrain models calculated by SAM calculation task and TruckMaker simulation package [1]. The interface component is exchanging the information between AVL CRUISE and TruckMaker and the
