摘要：
A control device diagnoses the operation of a bus arbiter that mediates bus usage requests output by multiple devices in the control device to satisfy both responsiveness and safety. A diagnostic module, implemented as an external diagnostic module, monitors signals related to the arbiter mediation and, if an abnormality caused by a signal sticking condition or an abnormality in a mediation control unit is detected, stops data transfer safely to prevent safety data from being output incorrectly.
摘要（中）：
控制装置诊断总线仲裁器的操作，其调节由控制装置中的多个装置输出的总线使用请求以满足响应性和安全性。 实施为外部诊断模块的诊断模块监视与仲裁者中介相关的信号，如果检测到信号粘连状况或中介控制单元异常引起的异常，则可以安全地停止数据传输，以防止安全数据成为 输出不正确。
