dSPACE adds simulation models for pneumatic brake and air suspension systems
October 30, 2013 by John Day
The ASM Pneumatics model library, which will become part of the dSPACE Automotive Simulation Models (ASM) product family, enables realistic brake simulation for commercial vehicles, and comfort functions for passenger vehicles.
ASM Pneumatics is ideal for developing and testing electronic brake systems (EBS), air suspension electronic control units (ECUs), level control ECUs, etc. ASM Pneumatics adds a complete realistic pneumatics system to the models for passenger vehicles (ASM Vehicle Dynamics), trucks (ASM Truck) and trailers (ASM Trailer).
The pneumatics model features click-to-select configurations for simulating air brake and air suspension systems. The graphical tool ModelDesk makes it easy to assign application-specific parameters. All the models, parameter sets and simulations can be handled seamlessly in one tool. This results in smooth, integrated data handling from offline simulation to hardware-in-the-loop (HIL) simulation.
Components of the Model
The ASM Pneumatics model includes all the components that are typical of real pneumatics systems, such as a compressor, tanks, valves and brake chambers. The model also supports fallback functionality for reverting to a purely mechanical brake system. Additionally, ASM Pneumatics supports the sequential addition of several trailers from the ASM library, so that road trains can be constructed and equipped with pneumatic brake systems.
