Assessing the use of RT-Java in automotive time-triggered applications

Abstract

Distributed embedded real-time systems are becoming widely used in several areas of application, including automotive systems. Most of these applications have severe timing constraints and are safety critical. A key component in distributed embedded real-time systems is to ensure a deterministic and reliable communication among distributed embedded systems. Especially in the automotive area, which is considering the possibility of replacing the major part of mechanical and/or hydraulic systems for electronic systems, the importance of a correct behavior in the electronic communication system plays a key role. This paper presents an platform-based embedded real-time system design methodology which can be used in automotive embedded real-time system design. The use of the proposed method is demonstrated through a steer-by-wire case study implemented using a Java platform.
