摘要: A method and apparatus for synchronous communication in a control system is disclosed. Within a first time interval, a first source task is executed to broadcast a first destination task, within a second sequential time interval, the first destination task is communicated over a channel to a first destination, and within a third sequential time interval, the first destination task is consumed. Within the first time interval, a second source task may be executed to broadcast a second destination task, within the second sequential time interval, the second destination task may be communicated over the channel to a second destination, and within the third sequential time interval, the second destination task may be consumed. The first source task is allowed to be scheduled ahead of the second source task, and the second source task is allowed to be scheduled ahead of the first source task.

摘要: A brake control system for brake by wire applications having a dual fail-silent pair controller architecture. The system utilizes two supervisory controllers and a shared monitoring controller to achieve the dual fail-silent pair configuration. The brake control system also features a mechanism whereby the monitoring controller ensures the fail-silent operation of the brake control units in the event of certain undesired events occurring within the system by assuming control of the affected brake control units. The control system further assures that no single event, including an event related to the monitoring controller, causes loss of more than half the braking functionality. The control system also features additional redundancy with regard to the brake command signals by sharing a separate unprocessed brake command signal with each of the supervisory controllers and the monitoring controller.
