摘要

面对未来汽车电子安全系统中应用软件组件密度的增加和可靠性要求的提高所带来的挑战，需要一种能够在运行时监控单个应用软件组件的可靠性软件服务，以提高整个系统的可靠性。本文提出了一个软件看门狗服务的应用，提供心跳监控和程序流检查。软件看门狗集成在汽车安全电子软件平台中。最后给出了基于Matlab/Simulink的模型设计，并在硬件在环验证器中对软件看门狗服务进行了评估。

Application of Software Watchdog as a Dependability Software Service for Automotive Safety Relevant Systems

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.
