Abstract: An automotive internal combustion engine electronic control unit for performing safety-related functions with a predetermined automotive safety integrity level, including: a microcontroller and an integrated circuit distinct from and communicating with the microcontroller. The microcontroller performs one or more safety-related functions with the same automotive safety integrity level as required to the automotive engine electronic control unit. The integrated circuit performs one or more safety-related functions with an automotive safety integrity level that is lower than that of the microcontroller. The integrated circuit performs, for each performed safety-related function, a corresponding diagnosis function for detecting failures in the performance of the safety-related function. The microcontroller performs, for each performed diagnosis function, a corresponding monitoring function for monitoring performance of the corresponding diagnosis function by the integrated circuit to detect failures that may compromise the diagnostic capability of the diagnosis function.
Abstract translation: 一种用于执行具有预定的汽车安全完整性级别的安全相关功能的汽车内燃机电子控制单元，包括：微控制器和与微控制器不同的通信的集成电路。 微控制器执行与汽车发动机电子控制单元所要求的相同的汽车安全完整性水平的一个或多个与安全相关的功能。 集成电路执行一个或多个与安全相关的功能，其汽车安全完整性级别低于微控制器。 对于每个执行的安全功能，集成电路执行用于检测安全功能的执行中的故障的相应诊断功能。 对于每个执行的诊断功能，微控制器执行相应的监视功能，用于通过集成电路监视相应诊断功能的性能，以检测可能危及诊断功能的诊断能力的故障。
