dSPACE Offers Virtual Pneumatics for Brakes and Suspension

November 3, 2013. Beginning in early 2014, dSPACE will offer simulation models for pneumatic brake and air suspension systems. 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 function simulation for passenger vehicles. ASM Pneumatics is suitable for developing and testing electronic brake systems (EBS), air-suspension electronic control units (ECUs), level control ECUs, and so on. ASM Pneumatics adds a complete realistic pneumatics system to the models for pas-senger 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.

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.
