CASTT

Through the Center for Automotive Systems Technologies and Testing (CAST), Luleå University of Technology aims to first of all support automotive winter testing in Northern Sweden.

To succeed in this task, the center relies on the university’s areas of leading research and most importantly on the cooperation between those areas.

The EIS Architecture group works on applying the Timber modeling approach to car systems. A multi-paradigm simulation environment is under development, with the aim to provide a tool for observing Timber models in the context of their environment expressed in Simulink. E.g.,  co-simulation of Timber models of control with vehicle dynamics.

In this project we also develop TinyTimber (TT), a C interface to a light-weight Timber Real-Time kernel.

TT allows legacy code to be migrated into the pure reactive design paradigm of Timber. Through the use of TT, the programmer is provided; concurrent reactive objects, state protection, synchronous and asynchronous messages, together with event based, deadline driven scheduling. In this way, TT aims to combine the benefits of minimalistic operating systems (such as tinyOS) with the real-time properties of fully fledged operating systems such as Real-Time Linux, requiring machines magnitudes larger than nodes typical for wireless embedded systems.

Ongoing work includes:

    porting TinyTimber to various embedded platforms

    performance evaluation of TinyTImber to other minimalistic operating systems and kernels
    implementing control algorithms in TinyTimber for steering the HALDEX 4wd system in a real production vehicle.
