摘要： Control information from a plurality of applications 1000 is written into a shared memory 101 as needed. A communication part 105 transmits the control information written in the shared memory 101 to a DHM 200 in each transmission cycle which is constant. In a management table, a plurality of allowable delay times is defined, the allowable delay time being a delay time allowable at an urgent transmission of the control information. A transmission timing notification part 106 divides a transmission cycle into time slots each of which is equal to or shorter than the shortest allowable delay time defined in the management table. The communication part 105 transmits the control information in the shared memory 101 to the DHM 200 before arrival of the transmission cycle, in a unit of time slot.

摘要： An increase in the number of signal lines of a control apparatus for controlling devices of an automobile can be prevented and safety of the automobile can be secured. An in-vehicle communication system includes an input DHM that obtains device data from an input device, a BCM that generates control data for controlling an output device based on a value of the device data, and an output DHM that controls the output device according to the control data. The input DHM is composed of duplexed input control blocks, duplexed input shared memories, and an input NW control block. The BCM is composed of a BCM_NW control block, duplexed BCM shared memories for different intended uses, and duplexed arithmetic blocks. The output DHM is composed of an output NW control block, duplexed output shared memories, duplexed output control blocks, and a matching circuit.

摘要： When a fixed-cycle transmission timing arrives, a fixed-period communication processing section transmits data in a shared memory to a BCM. An event table storage section stores an event table that indicates a condition of data to be transmitted by an event communication processing section and a permitted delay time, which is the period of time permitted starting from when the data satisfying the condition is extracted, until the data is transmitted. An event detecting section extracts the data in the shared memory satisfying the condition indicated by the event table. The event communication processing section transmits to the BCM the data extracted by the event detecting section, before the arrival of the transmission timing of the fixed-period communication processing section, and by the timing at which the permitted delay time elapses from the time of the data extraction by the event detecting section.
