To face the challenges resulting from the increasing density of application software components and higher dependability requirements of the future safety systems in the automotive electronics, a dependability software service to monitor individual application software components in runtime is required in order to improve the overall system dependability. This paper proposes the application of a Software Watchdog service providing heartbeat monitoring and program flow checking. The Software Watchdog is integrated in a software platform for the automotive safety electronics. A model-based design with Matlab/Simulink and an evaluation of this Software Watchdog service in a hardware-in-the-loop validator are also given.
Index Terms:
Software Watchdog, heartbeat monitoring, program flow checking, automotive dependable software platform and software services
