Abstract
Based on a count value held by a transmission counter, an information multiplex apparatus forms multiplexed transmission data by selecting or dividing at least part of each of two or more information items, based on the respective sizes of the two or more information items, a counter period of the transmission counter, and a transmission margin degree.
Claims18
An electronic control apparatus comprising:
- two or more information items to be updated at respective predetermined timings;
- an information multiplex apparatus that multiplexes the two or more information items;
- a transmission circuit that periodically transmits multiplexed transmission data outputted by the information multiplex apparatus;
- and
- a transmission counter that counts the number of transmissions transmitted by the transmission circuit,
- wherein based on a count value held by the transmission counter, the information multiplex apparatus forms the multiplexed transmission data by selecting or dividing at least part of each of the two or more information items, based on respective sizes of the two or more information items, a counter period of the transmission counter, and a transmission margin degree,
- wherein the electronic control apparatus further comprising:
- a reception circuit that receives the multiplexed transmission data transmitted by the transmission circuit;
- an information division apparatus that divides reception data received by the reception circuit;
- two or more information buffers in which the divided reception data items are stored;
- and
- two or more information processing apparatuses that obtain the two or more information buffers in two or more different periods,
- wherein the information multiplex apparatus multiplexes the two or more information items in such a way that each of all reception data items stored in the two or more information buffers is updated in an interval shorter than a period in which the two or more information processing apparatuses obtain the respective stored reception data items from the two or more information buffers, and
- wherein when the information division apparatus receives an error detection information, the information multiplex apparatus holds reception data stored in the information buffer.
