Abstract : Powertrain controllers are automotive applications that bring real-time constraints on software treatments based on the angular position of tooth in the motor. Theses constraints depend on the engine speed and can be as short as 100μsec. A time-triggered approach provides a predictable and reproducible execution of real-time systems but cannot cope with so tight constraints and does not allow to directly specifying the temporal behavior of the system based on angles. The contribution of this work is to present how the ability of the PharOS technology to combine several time domains (time and angle triggered) allows designing and executing powertrain controllers in a deterministic way on multi-core architectures. To this end, we present a prototype of a subset of a powertrain controller from Delphi based on PharOS.
