摘要： In order to detect and prevent attacks in which the network is infested with unauthorized data to cause malfunction, the invention aims, on the basis of network cycle information, to detect errors and to prevent unauthorized data forwarding in a network system such as a vehicle-mounted network. This network device is provided with a communication unit which receives data, a time management unit which manages the reception time at which data is received, and a control unit which processes data. If, for received data used as a reference, first data is received having the same identifier and a reception interval shorter than a prescribed cycle, the control unit waits to receive data having the same identifier as the first data from the reception time of the received data used as a reference up until the prescribed cycle has elapsed, and if during this interval second data is received having the same identifier as the first data, the control unit determines that an error has occurred and performs cycle abnormality detection processing (see Fig. 1 ).

摘要： There is provided means enabling effective selection of a method of combining software assets in the development of software that is hierarchized and segmented into components. Control software 101 created with a control software development tool 102 includes an application 103 which executes a control calculation process, a connection layer 104 which connects software components with each other, and basic software 114. In conventional software configurations, combination of software components hierarchized in the basic software is described by a standard I/F 108, and thus it has been difficult to flexibly change the method of combining software components adapting to the design change of the software. In the present invention, flexible selection of the method of combining software components is made possible by using template description for the method of combining software components.

摘要： In order to correctly execute a control task in a FlexRay-based vehicle-mounted network system, data synchronization must be guaranteed by completing transmission/reception of all data within a communication cycle. The control task is called in synchronization with a communication cycle. Frames within a communication cycle are partitioned into a first-half slot group and a second-half slot group, each of which is a set of consecutive frames. During the slots of the first-half slot group, a data transmission/reception unit writes transmission frames of the second-half slot group and reads the reception frames of the second-half slot group. During the slots of the second-half slot group, the transmission/reception unit writes the transmission frames, and reads the reception frames, of the first-half slot group.
摘要翻译：为了在基于FlexRay的车载网络系统中正确执行控制任务，必须通过在通信周期内完成所有数据的发送/接收来保证数据同步。与通信周期同步地调用控制任务。通信周期内的帧被划分为前半时隙组和后半时隙组，每个时隙组是一组连续帧。在前半时隙组的时隙期间，数据发送/接收单元写入后半时隙组的发送帧，并读取后半时隙组的接收帧。在第二半时隙组的时隙期间，发送/接收单元写入前半个时隙组的发送帧并读出接收帧。
