    摘要： A method of dynamically allocating a task or a signal on a statically allocated and embedded software architecture of a vehicle includes identifying a faulty component. The faulty component may include a software component, a hardware component or a signal or communications link between components. Once the faulty component is identified, any tasks performed by or signals associated with the faulty component are identified, and the tasks performed by or the signals associated with the faulty component are re-allocated to an embedded standby component so that performance of the re-allocated task and/or signal for future system operations is performed by the standby component.

    摘要： A vehicular distributed embedded real-time controller area network system includes ECUs functioning in an event-triggered mode for initiating transmission of a message to a communication bus. Each ECU includes a sending buffer for storing message. A bus controller interfaces with the ECUs and manages the transfer of messages to and from the communication bus. The transfer of messages onto the communication bus is executed by the bus controller on a periodic basis. The bus controller is unavailable to receive a message from an ECU when a previous message stored within a memory of the bus controller is awaiting transmission on the communication bus. The bus controller is available to receive a message from an ECU when the memory is empty. Messages are stored in the sender buffer when the bus controller is unavailable. A respective message within the sender buffer is transferred to the bus controller when the bus controller is available.

    摘要： A vehicular distributed embedded real-time controller area network system includes ECUs that function in an event-triggered mode to initiate a transmission of the message to the communication bus. Each ECU includes a sender buffer for storing the generated message. A bus controller interfaces with the ECUs and manages the transfer of messages to and from the communication bus. The transfer of messages onto the communication bus is executed by the controller area network controller on an interrupt basis. The bus controller being unavailable to receive a message from the ECU when a previous message stored within a memory of the bus controller is awaiting transmission on the communication bus. The bus controller is available to receive a message from the ECU when the memory is empty. The sender buffer stores messages received from the electronic control unit when the bus controller is unavailable. The ECU further includes a traffic shaping module for selectably delaying a transfer of messages to the bus controller.

    摘要： A method is provided for synchronizing time in an unsynchronized vehicle controller area network system. A master control unit receives a global time from a time synchronization source. The master control unit estimates a respective time delay in transmitting messages by electronic control units on each controller area network bus. The time delay is a difference between a time when a message is generated by a respective electronic control unit for transmission on a respective controller area network bus and a time when the message is transmitted on the respective controller area network bus. The global time is adjusted for each respective controller area network bus based on the estimated time delays associated with each respective controller area network bus. Global time messages from the master control unit are transmitted to each electronic control unit that include the adjusted global times for an associated controller area network bus.
