Title:
RELAY DEVICE, COMMUNICATION SYSTEM, TRANSMISSION METHOD AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/051833
Kind Code:
A1
Abstract:
For an ECU bus (14a), a control unit (36) of this relay device (10) calculates the ECU bus occupancy ratio, that is, the ratio per unit time occupied by transmission time during which data is transmitted. Next, on the basis of the calculated ECU bus occupancy ratio, the control unit (36) determines a transmission amount per unit time of partial data, which is part of update data for updating a computer program. A second communication unit (34a) repeatedly transmits the partial data over the ECU bus (14a) in the transmission amount per unit time determined by the control unit (36).
