Title:
RELAY DEVICE SYSTEM
Document Type and Number:
Japanese Patent JP2020053780
Kind Code:
A
Abstract:
To provide a relay device system capable of increasing the redundancy of communication between inside-vehicle and outside-vehicle when relaying communication from outside a vehicle to an ECU mounted in the vehicle.SOLUTION: A relay device system S mounted on a vehicle 1 includes: a wireless relay device 100 for wirelessly communicating with a communication device provided outside the vehicle; a plurality of wired relay device 20 connected with the wireless relay device in a ring; and an inside-vehicle network 3 formed in a ring by a communication line that connects the wireless relay device and the plurality of wired relay devices. The plurality of wired relay devices include an ECU communication unit for communicatively connecting with ECUs 31, 32, and 33 for controlling an on-vehicle device mounted on the vehicle. The wireless relay device and the plurality of wired relay devices communicate via an in-vehicle network by two routes of clockwise and anticlockwise.SELECTED DRAWING: Figure 1
