Title:
ONBOARD CONNECTION SYSTEM AND ONBOARD SYSTEM DESIGN METHOD
Document Type and Number:
WIPO Patent Application WO/2023/167004
Kind Code:
A1
Abstract:
In the present invention, zone ECUs (10A) are respectively disposed in a plurality of areas (A1-A4) partitioned on a vehicle, and each zone ECU (10A) controls a first device (20) disposed in the same area. Independent ECUs (11, 12) are disposed, and each independent ECU (11, 12) controls a second device of a functional group (G1, G2) independent from control of the zone ECUs (10A) regardless of the partitioning of the areas. A central ECU (30) that manages the zone ECU (10A) of each area and the independent ECUs (11, 12) is disposed. Power source inputs of an onboard power source (35), the zone ECUs (10A), and the central ECU (30) are connected by first power source connection paths (41, 42), and power source inputs of the onboard power source (35) and the independent ECUs (11, 12) are connected by second power source connection paths (46, 47). The power source power to the second device is supplied from the independent ECUs.
