Run time safety analysis for automotive systems in an open and adaptive environment.

Cooperative vehicles are no longer fiction. A key factor is the abilityfor vehicles to exchange information with their environment. The shared informationcan be used to realize new functionalities, from virtual traffic lights toemergency braking, thus with potential to increase safety and efficiency of vehiclesystems. However, external information has inherent uncertainties and thisposes a threat to safety. In this paper we will discuss how to handle these uncertaintiesby use of dynamic safety contracts. We propose an extension toAUTomotive Open System Architecture (AUTOSAR) which consists of a safetymanager which actively enforces the safety rules described in such safetycontract. We also propose to integrate the architecture of an IntelligentTransport System (ITS) station tightly to AUTOSAR. It is our hypothesis thatsuch architecture provides a viable platform for run time safety assessment. Futureresearch work is to evaluate what kind of safety assessments our systemcan be able to handle
