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).
Counterfeit components and manipulation of electronic control unit coding are two growing problems for automakers. Counterfeiting can result in significant financial loss annually and possible safety risks. Code manipulation (chip tuning) is both a safety and liability issue.
To help control the problem, Infineon Technologies is launching a series of automotive microcontrollers (MCUs) with hardware-based security features, including a protected secret key and encryption engines. Intended for power train and chassis applications, the new devices include a “Secure Hardware Extension” (SHE). The hardware extension addresses security functions described by the “HIS” (Manufacturers’ Software Initiative) Working Group on Security, members of which include Audi, BMW, Daimler, Porsche and Volkswagen.

It’s impossible to tell from outside Toyota what is causing their reliability issues but there is reason to suspect that the cause has to do with network complexity. Cars are complex, networked systems. Frequently a single function – like braking – involves multiple computers, or electronic control units (ECUs), as well as a lot of application software, communication software stacks, and operating systems.

Today’s automotive challenges are similar to those experienced in the telecommunications industry more than ten years ago. New technologies, such as hybrid-electric and fuel cell vehicles, are hotbeds of research and development activity comparable to what we saw during the evolution of cell phones into multimedia devices. In the same way that the telecomm industry faced power and chip size limitations, automotive designers are being stretched to include more and more technology into what used to be basically a mechanical device.
