Modelling feature interactions in the automotive domain

We propose to use model checking to detect feature interactions in a set of features under design for an automotive embedded system. In this paper, we present (1) the characteristics of the feature interaction problem in the automotive domain that make model checking an appropriate detection technique; (2) our proposal for a general, systematic definition of feature interactions for this domain based on the set of actuators in the vehicle influenced by the features; and (3) our solutions to two modelling issues that arise when creating a description in SMV of the behaviour of an integrated set of automotive features designed in MATLAB's STATEFLOW.
