ASM Truck Trailer Pneumatics Model

The ASM Truck Trailer Pneumatics Model demonstrates the handling and behavior of automotive ASM pneumatic components using the ASM Truck Trailer Demo model 

as background. The model includes air supply, air brakes and air suspension for truck and trailer. This allows typical applications such as ABS braking or level control.

A complete overview over all ASM pneumatic components can be found in the product documentation of ASM Pneumatics.

Installation

1. Please get an ASM Truck Trailer demo model from the dSPACE installation and download the ASM_TruckTrailer_Pneumatics .zip-file for your dSPACE release linked below.

2. The .zip-file contains the ASM_TruckTrailer_Pneumatics.slx, a suitable go file and all initialization files required for parameterizing the pneumatics system of the truck trailer variants for a truck with full trailer and a truck with semi-trailer. Extract the complete .zip folder.

3. Copy the content of the extracted folder into the Simulation folder of the ASM Truck Trailer Demo project.

4. When you do this, you must confirm that the files already saved to the destination folder can be replaced.

5. Now the ASM Truck Trailer Pneumatics Model can be used in MATLAB like all other ASM demo models.

Attention:

Additionally, in case the downloaded .zip file has been created for an older release than the release the Truck Trailer demo project has been created in, some adjustments to the asm_xxx_ini.m files in the subfolders of the folders %root path%\_TruckFullTrailer\IniFiles and %root path%\_TruckSemiTrailer\IniFiles may be necessary. So, if there are issues when executing the go.m file, make sure, that the asm_xxx_ini.m files list all initialization files and only those in the folder they are members from.

Parametrization

1. A ModelDesk parameterization project is already included in the ASM Truck Trailer demo and can be reconfigured for the ASM Truck Trailer Pneumatics demo model. After the ModelDesk project has been opened, the simulation model file of the ModelDesk project must be changed to ASM_TruckTrailer_Pneumatics.slx. Afterwards, all ASM Pneumatics components can be parameterized using ModelDesk.

Attention:

While changing the simulation model file ModelDesk parses the selected model and updates the project tree of the parameter set according to the ASM library blocks it has found in the model. Especially, it adds entries for the additional library blocks for modelling the air brake and the air suspension that are not part of the default Truck Trailer demo model. Therefor, it uses default parameters that – under certain circumstances - may differ from those defined in the ini files in the Simulation folder. So, if there are issues with the simulation results after downloading parameters from or using the Generate ini files… function in ModelDesk, make sure, that the parameters in ModelDesk and in the ini files in the Simulation folder are consistent.
